技术领域Technical field

本发明涉及通信技术领域，更为具体地说，涉及一种电源信号复合缆。The present invention relates to the field of communications technologies, and more particularly to a power signal composite cable.

背景技术Background technique

随着数据通信技术和信息技术的高速发展，网络对综合布线***的性能要求越来越高。目前的网络布线***中，电缆与信号缆采用分别铺设的模式会造成线缆密集无序，线缆铺设成本高，铺设施工复杂等弊端，因此越来越不适应新技术发展的布线要求。取而代之的电源信号复合缆越来越多地应用到网络布线***中。电源信号复合缆指的是信号缆中增加了绝缘导体形成的集信号线和输电线为一体的线缆。电源信号复合缆能够同时解决设备用电和信号传输问题，保留信号缆特性的同时还能够满足电缆的相关要求。With the rapid development of data communication technology and information technology, the performance requirements of the network for integrated wiring systems are getting higher and higher. In the current network cabling system, the cable and signal cable are separately laid in a mode that causes cable intensive disorder, high cable laying cost, complicated laying and other disadvantages, and thus is increasingly unsuitable for the wiring requirements of new technology development. Instead, power signal composite cables are increasingly being used in network cabling systems. The power signal composite cable refers to a cable in which the signal conductor and the power transmission line formed by the insulated conductor are integrated into the signal cable. The power signal composite cable can solve the problem of power consumption and signal transmission of the equipment at the same time, and retain the characteristics of the signal cable while meeting the relevant requirements of the cable.

目前，电源信号复合缆仅仅作为电和信号的传输载体，通过与之对接的外接设备实现信息的采集、发送、交互等功能。在对接过程中，电源信号复合缆需要通过截断、对接、分路等物理操作实现与外接设备的对接。此操作比较繁琐，导致现场的布线施工效率低。而且，电源信号复合缆与外接设备对接过程中，外接设备需要额外的固定装置和空间，而且外接设备一旦固定到位后不易调整和挪动，这导致整个综合布线***缺乏足够的柔性。At present, the power signal composite cable is only used as a transmission carrier for electric and signal, and realizes functions of collecting, transmitting, and interacting with information through an external device that is connected thereto. In the docking process, the power signal composite cable needs to be connected to the external device through physical operations such as cutting, docking, and splitting. This operation is cumbersome, resulting in low efficiency of wiring construction on site. Moreover, in the process of docking the power signal composite cable with the external device, the external device requires additional fixing devices and space, and the external device is not easy to adjust and move once it is fixed in place, which results in lack of sufficient flexibility of the entire integrated wiring system.

实施例一 Embodiment 1

请参考附图1-3，图1是本发明实施例一提供的电源信号复合缆的部分结构示意图。图2是本发明实施例一提供的电源信号复合缆设有十字节点设备部位的横向剖视图。图3是本发明实施例一提供的电源信号复合缆含有基材线缆部位的横向剖视图。Referring to FIG. 1-3, FIG. 1 is a partial structural diagram of a power signal composite cable according to Embodiment 1 of the present invention. 2 is a transverse cross-sectional view showing a portion of a power signal composite cable provided with a cross node device according to Embodiment 1 of the present invention. 3 is a transverse cross-sectional view of a power signal composite cable provided with a substrate cable portion according to Embodiment 1 of the present invention.

本发明实施例一提供的电源信号复合缆包括至少两段基材线缆、十字节点设备7和封塑外护套10。The power signal composite cable provided by the first embodiment of the present invention includes at least two pieces of substrate cable, a cross node device 7 and a molded outer sheath 10.

每段基材线缆均包括第一信号线5、第二信号线6、火线2、地线3和基材线缆外护套1。Each of the substrate cables includes a first signal line 5, a second signal line 6, a live line 2, a ground line 3, and a substrate cable outer sheath 1.

The substrate cable outer sheath 1 is wrapped around the cable bundle formed by the first signal line 5, the second signal line 6, the live wire 2, and the ground wire 3, and is a peripheral protective member of the substrate cable. Generally, the outer sheath 1 of the substrate cable can be made of PVC (Polyvinyl chloride) material, LSZH (Low Smoke Zero Halogen) material or PE (polyethylene) material. In one embodiment, the outer sheath 1 of the substrate cable has a diameter of 10 mm and a thickness of 1.5 mm. The first embodiment of the present invention does not limit the size of the outer sheath 1 of the substrate cable, and those skilled in the art can adjust the size of the outer sheath 1 of the substrate cable to adapt to the wiring environment. Of course, the outer sheath 1 of the substrate cable can also be made of other materials, and the material of the outer sheath 1 of the substrate cable is not limited in this application.

Preferably, the conductive copper wire C is a multi-core conductive copper wire to improve the stability of electrical transmission. The insulating sheath B may be a PVC material, a LSZH material or a PE material. FireWire 2 and Ground 3 can be distinguished by different colors. Typically, the live wire 2 has a red outer skin, ie the insulating sheath of the live wire 2 is red. The ground wire 3 has a black outer skin, that is, the insulating sheath of the ground wire 3 is black. FireWire 2 and Ground Wire 3 can also be distinguished by other symbols such as text symbols.

第一信号线5和第二信号线6的结构可以相同，均可以包括信号铜丝E和包覆于信号铜丝E上的封塑护套D。优选的，信号铜丝E为多芯信号铜丝，以提高信号传输的稳定性。封塑护套D的材料可以为PVC材料、LSZH材料或PE材料。更为优选的，第一信号线5和第二信号线6均可以设置有防止错接的信号线识别标识，例如颜色标识、文字标识(例如编号)等。The structures of the first signal line 5 and the second signal line 6 may be the same, and may each include a signal copper wire E and a sealing sheath D coated on the signal copper wire E. Preferably, the signal copper wire E is a multi-core signal copper wire to improve the stability of signal transmission. The material of the sealing sheath D may be a PVC material, an LSZH material or a PE material. More preferably, the first signal line 5 and the second signal line 6 may each be provided with a signal line identification mark that prevents misconnection, such as a color mark, a character mark (for example, a number), and the like.

请结合参考附图4，十字节点设备7用于连接相邻的两段基材线缆。本实施例一中，十字节点设备7具有PCB，通过在PCB上布置信号处理模块和信号收发模块，以实现与背景技术中所述外接设备相同的功能，例如信号采集、收发、交互等功能。十字节点设备7的十字形结构的四个象限区域内均设置有十字焊接焊点4。相邻的两段基材线缆中对应的第一信号线5、第二信号线6、火线2和地线 3分别通过四个象限区域内的十字焊接焊点4相连，从而使得十字节点设备7与第一信号线5、第二信号线6、火线2和地线3的信息交互、动力连接。Referring to Figure 4 in conjunction with Figure 4, the cross node device 7 is used to connect adjacent two lengths of substrate cables. In the first embodiment, the cross node device 7 has a PCB, and the signal processing module and the signal transceiving module are arranged on the PCB to implement the same functions as the external devices described in the background, such as signal acquisition, transceiving, and interaction. Cross weld pads 4 are provided in the four quadrant regions of the cross-shaped structure of the cross node device 7. Corresponding first signal line 5, second signal line 6, hot line 2 and ground line of adjacent two-stage substrate cables 3 is connected through the cross solder joints 4 in the four quadrant regions, respectively, so that the cross node device 7 interacts and powers the information of the first signal line 5, the second signal line 6, the live line 2, and the ground line 3.

封塑外护套10是整个电源信号复合缆的***防护部件，整体封塑在各个基材线缆和十字节点设备7之外。封塑外护套10可以与基材线缆外护套1的材质相同，也可以不同。封塑外护套10通常采用阻燃材料制成，即封塑阻燃外护套。The molded outer sheath 10 is a peripheral protective member of the entire power signal composite cable, and is integrally sealed outside the respective substrate cables and the cross node device 7. The molded outer sheath 10 may be the same as or different from the material of the outer sheath 1 of the substrate cable. The outer jacket 10 is usually made of a flame retardant material, that is, a flame-retardant outer sheath.

本实施例一提供的电源信号复合缆中，将十字节点设备7与基材线缆集成为一体式结构。这种一体式结构的电源信号复合缆不用外接其它外接模块就可以实现动力和信号传输，以及信号收发和处理等功能。在网络布线***的现场布线过程中，本实施例一提供的电源信号复合缆无需通过截断、对接、分路等物理操作与外接设备对接，能够简化现场布线操作，进而提高现场的布线效率。In the power signal composite cable provided in the first embodiment, the cross node device 7 and the substrate cable are integrated into an integrated structure. The power signal composite cable of the integrated structure can realize power and signal transmission, as well as signal transmission and reception and processing functions without external external modules. In the field wiring process of the network cabling system, the power signal composite cable provided in the first embodiment does not need to be connected to the external device through physical operations such as cutting, docking, and shunting, which can simplify the field wiring operation and improve the wiring efficiency in the field.

由于十字节点设备7内置于封塑外护套10之内，所以无需设置额外的固定装置和空间，这进一步能够简化现场布线操作，进而提高现场布线效率。电源信号复合缆无需额外的固定装置和空间，也就使得十字节点设备7在移动的过程中无需受固定装置和空间的限制，而且操作人员可以通过打弯或盘绕电源信号复合缆的方式来微调十字节点设备7的位置。可见，本实施例一提供的电源信号复合缆便于外接设备位置的调整，使得外接设备位置的设置和变动较为灵活，而且也能够减少占用空间。Since the cross-node device 7 is built into the outer jacket 10, there is no need to provide additional fixtures and spaces, which further simplifies field wiring operations and thereby improves field wiring efficiency. The power signal composite cable does not require additional fixtures and space, so that the cross node device 7 does not need to be limited by the fixture and space during the movement, and the operator can fine tune the method by bending or coiling the power signal composite cable. The location of the cross node device 7. It can be seen that the power signal composite cable provided in the first embodiment facilitates the adjustment of the position of the external device, so that the setting and the change of the location of the external device are flexible, and the occupied space can also be reduced.

同时，操作人员通过操作电源信号复合缆整体来调整十字节点设备7的位置，便于局部布线的优化，以达到更好的使用效果。本实施例一中，十字节点设备7可以形成于电源信号复合缆的任意位置，现场施工人员可以根据具体的施工环境合理地确定十字节点设备7的布设位置，进而适用于各种复杂的现场接线环境，降低布线难度。At the same time, the operator adjusts the position of the cross node device 7 by operating the power signal composite cable as a whole to facilitate the optimization of the local wiring to achieve a better use effect. In the first embodiment, the cross node device 7 can be formed at any position of the power signal composite cable, and the on-site construction personnel can reasonably determine the layout position of the cross node device 7 according to the specific construction environment, and is applicable to various complicated field wirings. Environment, reducing wiring difficulty.

综上可知，本实施例一提供的电源信号复合缆能够使得整个综合布线***具有足够的柔性。In summary, the power signal composite cable provided in the first embodiment can make the entire integrated wiring system have sufficient flexibility.

本实施例一提供的电源信号复合缆中，第一信号线5、第二信号线6、火线2和地线3中，任意两者的外径之差较小。优选的，上述任意两条线缆的外径之差可以小于1mm。这使得火线2、地线3、第一信号线5和第二信号线6的直径较为均衡，进而当整个电源信号复合缆受到外力时，第一信号线5、第二信号线6、地线3和火线2的受力较为均匀，能够避免第一信号线5、第二信号线6、地线3和火线2由于尺寸差异较大造成的应力集中问题，能够解决各个线缆与十字节点设备7连接后由不均衡的内应力引起的接线可靠性降低问题。更为优选的，火线2、地线3、第一信号线5和第二信号线6的外径可以相等，以进一步缓解应力集中。In the power signal composite cable provided in the first embodiment, the difference between the outer diameters of any two of the first signal line 5, the second signal line 6, the live line 2, and the ground line 3 is small. Preferably, the difference between the outer diameters of any two of the above cables may be less than 1 mm. This makes the diameters of the live wire 2, the ground wire 3, the first signal line 5, and the second signal line 6 relatively balanced, and then the first signal line 5, the second signal line 6, and the ground line when the entire power signal composite cable receives an external force. 3 and the fire line 2 is more evenly stressed, and can avoid the stress concentration problem caused by the large difference in size between the first signal line 5, the second signal line 6, the ground line 3, and the live line 2, and can solve each cable and cross node device. 7 The problem of reduced wiring reliability caused by unbalanced internal stress after connection. More preferably, the outer diameters of the live wire 2, the ground wire 3, the first signal line 5, and the second signal line 6 may be equal to further alleviate stress concentration.

请参考附图4和图5，本实施例一提供的十字节点设备7可以包括第一PCB(Printed Circuit Board，印刷电路板)11和第二PCB12，第一PCB11和第二 PCB12形成十字形结构。第一PCB11和第二PCB12上设置有使得十字节点设备7发挥其特定功能的电子元器件。第一PCB11和第二PCB12可以通过多种方式形成十字节点设备7的十字形结构，例如通过连接件或连接结构连接。第一PCB11和第二PCB12形成十字形结构，能够大大提高十字节点设备7的抗扭性能，进而能够有效防止在扭力存在时第一PCB 11和第二PCB12上元器件脱落，从而能够提高十字节点设备7在实际应用中的可靠性。Referring to FIG. 4 and FIG. 5, the cross node device 7 provided in the first embodiment may include a first PCB (Printed Circuit Board) 11 and a second PCB 12, and the first PCB 11 and the second The PCB 12 forms a cross-shaped structure. The first PCB 11 and the second PCB 12 are provided with electronic components that cause the cross node device 7 to perform its specific function. The first PCB 11 and the second PCB 12 may form a cross-shaped structure of the cross-node device 7 in various ways, for example, by a connector or a connection structure. The first PCB 11 and the second PCB 12 form a cross-shaped structure, which can greatly improve the torsional resistance of the cross-node device 7, thereby effectively preventing components on the first PCB 11 and the second PCB 12 from falling off when the torque is present, thereby improving the cross node. The reliability of the device 7 in practical applications.

同时，第一PCB11和第二PCB12形成的十字形结构使得两块PCB的两面均可以作为电子元器件安装面。这能够增加电子元器件的可安装位置，最终能够提高第一PCB11和第二PCB12的空间利用率。At the same time, the cross structure formed by the first PCB 11 and the second PCB 12 allows both sides of the two PCBs to serve as electronic component mounting surfaces. This can increase the mountable position of the electronic component and ultimately improve the space utilization of the first PCB 11 and the second PCB 12.

具体的，第一PCB11和第二PCB12可以通过卡接相连。第一PCB11上设置有第一连接部位，第二PCB12上设置有第二连接部位。第一连接部位和第二连接部位卡接，以使得第一PCB11和第二PCB12相连而形成十字形结构。其中，第一连接部件和第二连接部件有多种不同的实现方式。Specifically, the first PCB 11 and the second PCB 12 may be connected by a card. The first PCB 11 is provided with a first connection portion, and the second PCB 12 is provided with a second connection portion. The first connection portion and the second connection portion are engaged to connect the first PCB 11 and the second PCB 12 to form a cross-shaped structure. There are a plurality of different implementations of the first connecting member and the second connecting member.

在实际的应用过程中，第一PCB11和第二PCB12通过卡接的连接方式，可能不足以满足第一PCB11和第二PCB12之间的稳固性及实用性。为此，十字焊接焊点4可以通过锡焊焊接在第一PCB11和第二PCB12的卡接处，进而起到辅助连接第一PCB11和第二PCB12的作用。第一PCB11和第二PCB12之间可能具有多个卡接部位，多个卡接部位分别位于十字节点设备7的不同部位。优选的，每个卡接部位均设置有十字焊接焊点4，以进一步提高十字节点设备7结构的稳固性和实用性。十字焊接焊点4可以设置在第一PCB11和第二PCB12卡接处，还可以设置在第一PCB11和第二PCB12除卡接处之外的其它部位，以进一步提高第一PCB11和第二PCB12连接的稳固性。In the actual application process, the connection manner of the first PCB 11 and the second PCB 12 through the card connection may not be sufficient to satisfy the stability and practicability between the first PCB 11 and the second PCB 12. To this end, the cross solder joint 4 can be soldered to the junction of the first PCB 11 and the second PCB 12, thereby functioning to assist in connecting the first PCB 11 and the second PCB 12. There may be a plurality of latching portions between the first PCB 11 and the second PCB 12, and the plurality of latching portions are respectively located at different parts of the cross node device 7. Preferably, each of the engaging portions is provided with a cross solder joint 4 to further improve the stability and practicability of the structure of the cross node device 7. The cross solder joint 4 may be disposed at the junction of the first PCB 11 and the second PCB 12, and may also be disposed at other portions of the first PCB 11 and the second PCB 12 except the snap joint to further improve the first PCB 11 and the second PCB 12 The stability of the connection.

在连接线缆的过程中，第一信号线5、第二信号线6、火线2和地线3分别与位于不同象限区域内的相应部位的十字焊接焊点4焊接。十字焊接焊点4能够增加抗拉力，进而避免第一PCB11和第二PCB12上焊盘脱落或线缆脱落，能够增强连接的稳定性。In the process of connecting the cables, the first signal line 5, the second signal line 6, the live line 2, and the ground line 3 are respectively soldered to the cross solder joints 4 of the respective portions located in different quadrant regions. The cross-weld solder joint 4 can increase the tensile force, thereby preventing the pads on the first PCB 11 and the second PCB 12 from falling off or the cables from falling off, which can enhance the stability of the connection.

请参考附图5，十字焊接焊点4在第一PCB11和第二PCB12均形成受锡面(即第一受锡面401和第二受锡面402)，即形成双面受锡。这种十字焊接焊点4形成方式能够提高十字焊接焊点4与各个线缆(即第一信号线5、第二信号线6、火线2和地线3)的焊接强度，进而提高十字节点设备7，甚至整个电源信号复合缆的抗拉抗扭性能。Referring to FIG. 5, the cross solder joint 4 forms a tin-receiving surface (ie, a first tin-receiving surface 401 and a second tin-receiving surface 402) on both the first PCB 11 and the second PCB 12, that is, a double-sided tin-forming layer is formed. The cross solder joint 4 is formed in such a manner as to improve the welding strength of the cross solder joint 4 and the respective cables (ie, the first signal line 5, the second signal line 6, the hot line 2, and the ground line 3), thereby improving the cross node device. 7, even the entire power signal composite cable tensile and torsion resistance.

各个线缆与十字焊接焊点4焊接的过程中，线缆需要去掉外皮使其暴露出的内芯与十字焊接焊点4焊接。为了避免位于十字节点设备7同一端的线缆之间由于内芯暴露而可能出现接触短路，上述十字焊接焊点4的位置不能太靠近第一PCB11和第二PCB12的端面，如第一PCB11和第二PCB12的左端或右端，以使得十字形结构能够将各个线缆暴露的内芯隔离开。优选的，十字焊接焊点4距离第一PCB11和第二PCB12的端部预设距离。本领域技术人员可以根据实际操作过程中线缆的内芯暴露长度来设定预设距离的大小，通常预设距离的大小为经验值。During the welding of the individual cables to the cross solder joint 4, the cable needs to be stripped of the outer skin so that the exposed inner core is welded to the cross solder joint 4. In order to avoid contact short circuit between the cables at the same end of the cross node device 7 due to the inner core exposure, the position of the above-mentioned cross solder joint 4 cannot be too close to the end faces of the first PCB 11 and the second PCB 12, such as the first PCB 11 and the first The left or right end of the second PCB 12, so that The cross-shaped structure isolates the exposed core of each cable. Preferably, the cross solder joint 4 is spaced apart from the ends of the first PCB 11 and the second PCB 12 by a predetermined distance. A person skilled in the art can set the preset distance according to the inner core exposure length of the cable during the actual operation, and the preset distance is usually an empirical value.

本实施例一中，第一PCB11和第二PCB12的长度可以相等，也可以不等。优选的，第一PCB11和第二PCB12的长度相等。另外，第一PCB11和第二PCB12的长度越短，越有利于使得整个电源信号复合缆的回弯半径满足布线要求，也有利于提高整个电源信号复合缆的抗扭性能。当第一PCB11和第二PCB12的长度和宽度分别保持一致时，形成的十字节点设备更有利于优先注塑成圆柱体A(如图1所示)，然后再继续注塑以形成封塑外护套10。In the first embodiment, the lengths of the first PCB 11 and the second PCB 12 may be equal or different. Preferably, the first PCB 11 and the second PCB 12 are equal in length. In addition, the shorter the length of the first PCB 11 and the second PCB 12, the more favorable the loopback radius of the entire power signal composite cable satisfies the wiring requirements, and also helps to improve the torsional performance of the entire power signal composite cable. When the length and width of the first PCB 11 and the second PCB 12 are respectively consistent, the formed cross node device is more advantageous for preferential injection molding into the cylinder A (as shown in FIG. 1), and then continues to be injection molded to form a sealed outer sheath. 10.

此外，第一PCB11和第二PCB12均具有一定厚度，优选的，第一PCB11和第二PCB12的厚度相等，也能够提高十字节点设备7的抗扭性。具体的，第一PCB1和第二PCB2可为单层板或多层板。In addition, both the first PCB 11 and the second PCB 12 have a certain thickness. Preferably, the thicknesses of the first PCB 11 and the second PCB 12 are equal, and the torsional resistance of the cross node device 7 can also be improved. Specifically, the first PCB 1 and the second PCB 2 may be a single layer board or a multi-layer board.

目前，电源信号复合缆中，第一信号线5、第二信号线6、火线2和地线3为普通的集束结构，这种电源信号复合缆在与十字节点设备7相连时容易产生旋钮，进而使得第一信号线5、第二信号线6、火线2和地线3产生较大的扭力，进而造成电源信号复合缆中的各个线缆的接头处于旋钮绷紧状态。这种状态会导致地线3、火线2、第一信号线5、第二信号线6处于离散状态，最终导致电源信号复合缆的端部接线困难。为了解决此问题，本实施例一提供的电源信号复合缆中，地线3、火线2、第一信号线5和第二信号线6沿着电源信号复合缆的中轴线层绞分布。第一信号线5、第二信号线6、火线2和地线3采用层绞分布的方式，使得整个电源信号复合缆在遭受扭力时本身就具有顺着扭力方向恢复的作用力，这最终会降低扭力对各个线缆的影响，进而解决电源信号复合缆的端部接线困难的问题。At present, in the power signal composite cable, the first signal line 5, the second signal line 6, the live line 2, and the ground line 3 are ordinary bundle structures, and the power signal composite cable is easy to generate a knob when connected to the cross node device 7. Further, the first signal line 5, the second signal line 6, the live line 2, and the ground line 3 generate a large torque, thereby causing the joints of the respective cables in the power signal composite cable to be in a knob tension state. This state causes the ground line 3, the live line 2, the first signal line 5, and the second signal line 6 to be in a discrete state, which ultimately causes difficulty in wiring the end portion of the power signal composite cable. In order to solve this problem, in the power signal composite cable provided in the first embodiment, the ground line 3, the live line 2, the first signal line 5, and the second signal line 6 are distributed along the central axis of the power signal composite cable. The first signal line 5, the second signal line 6, the live line 2 and the ground line 3 are distributed in a layered manner, so that the entire power signal composite cable itself has a force to recover in the direction of the torsion when subjected to the torsion force, which will eventually Reduce the impact of torque on each cable, and then solve the problem of difficult wiring at the end of the power signal composite cable.

更为优选的，本实施例一提供的电源信号复合缆还包括屏蔽层，用于屏蔽外接电磁信号对第一信号线5和第二信号线6的影响。屏蔽层依附于基材线缆外护套1内，且包覆于第一信号线5、第二信号线6、火线2和地线3所形成的线缆束上。在十字节点设备7与第一信号线5、第二信号线6、火线2和地线3连接后，屏蔽层再与地线3相连，用于将外界电磁干扰信号接地，这能够较好地消除外界电磁干扰信号。具体的，请再次参考附图3，屏蔽层包括位于外层的编织铜丝层8和位于内层的绕包带层9，绕包带层9贴附于编织铜丝层8之内，用于裹紧线缆束。在十字节点设备7与第一信号线5、第二信号线6、火线2和地线3相连后，编织铜丝层8再与地线3相连，用于将外界电磁干扰信号接地，即消除外界电磁干扰信号。具体的，编织铜丝层8可以为编织铜丝网。绕包带层9可以为聚脂薄膜绕包带层或半导体绕包带层。More preferably, the power signal composite cable provided in the first embodiment further includes a shielding layer for shielding the influence of the external electromagnetic signal on the first signal line 5 and the second signal line 6. The shielding layer is attached to the outer sheath 1 of the substrate cable and covered on the cable bundle formed by the first signal line 5, the second signal line 6, the live line 2 and the ground line 3. After the cross node device 7 is connected to the first signal line 5, the second signal line 6, the live line 2 and the ground line 3, the shielding layer is connected to the ground line 3 for grounding the external electromagnetic interference signal, which can be better Eliminate external electromagnetic interference signals. Specifically, referring again to FIG. 3, the shielding layer includes a braided copper wire layer 8 on the outer layer and a wrapping tape layer 9 on the inner layer, and the wrapping tape layer 9 is attached to the braided copper wire layer 8 for use. Tighten the cable bundle. After the cross node device 7 is connected to the first signal line 5, the second signal line 6, the live line 2 and the ground line 3, the braided copper wire layer 8 is connected to the ground line 3 for grounding the external electromagnetic interference signal, that is, eliminating External electromagnetic interference signal. Specifically, the braided copper wire layer 8 may be a braided copper wire mesh. The wrapping tape layer 9 may be a polyester film wrapping tape layer or a semiconductor wrapping tape layer.

十字节点设备7为十字形结构，第一信号线5、第二信号线6、火线2和地线3分别位于十字形结构的四个象限内，进而使得第一信号线5、第二信号线6、火线2和地线3呈十字状分布，这种分布方式使得电源信号复合缆的结构更加稳定，能够进一步避免应力集中。另外，十字节点设备7起到较好的支撑作用，使得整个电源信号复合缆强度增加和抗扭力效果更好，同时能够避免第一PCB11和第二PCB12上的电子元器件由于受扭力而脱落。The cross node device 7 has a cross-shaped structure, a first signal line 5, a second signal line 6, a fire line 2, and a ground The lines 3 are respectively located in the four quadrants of the cross-shaped structure, so that the first signal line 5, the second signal line 6, the live line 2 and the ground line 3 are distributed in a cross shape, and the distribution mode makes the structure of the power signal composite cable more Stable, can further avoid stress concentration. In addition, the cross node device 7 plays a better supporting role, so that the strength of the composite power cable and the anti-torque effect are better, and the electronic components on the first PCB 11 and the second PCB 12 can be prevented from falling off due to the torsion.

请再次参考附图1，本发明实施例一提供的更为优选的电源信号复合缆的制作过程如下：以基材线缆(指的是未添加十字节点设备7和一体式封塑阻燃外护套10)为操作对象，操作人员剥除两段基材线缆连接端的部分基材线缆外护套1，然后剥离连接端编织铜丝层8，再然后去除绕包带层9，用剥线钳分别去除第一信号线5、第二信号线6、火线2和地线3的外皮，把相连两段第一信号线5、第二信号线6、火线2和地线3的剥离端分别通过十字节点设备四个象限区域内的十字焊接焊点4相连，使各个线缆分布在各自对应的象限区域内。然后，将编织铜丝层8与地线3相连。再然后整体注塑灌封封塑外护套10。具体的，在封塑外护套10的过程中，可以先将剥离区域重新注塑灌封，使得注塑灌封区域与基材线缆的其它部位直径相等，最后在整体最外层封塑，以最终形成封塑外护套10。Referring to FIG. 1 again, a more preferred power signal composite cable provided by the first embodiment of the present invention is as follows: a substrate cable (refers to the non-added cross node device 7 and the integrated package flame retardant) The sheath 10) is an operation object, the operator peels off part of the substrate cable outer sheath 1 of the two-stage substrate cable connection end, and then peels off the connection end braided copper wire layer 8, and then removes the wrapping tape layer 9 and strips the strip The tongs respectively remove the outer skins of the first signal line 5, the second signal line 6, the hot line 2 and the ground line 3, respectively, and the stripped ends of the first two signal lines 5, the second signal line 6, the hot line 2 and the ground line 3 are respectively connected The cross-welded solder joints 4 in the four quadrant regions of the cross-node device are connected such that the respective cables are distributed in respective corresponding quadrant regions. Then, the braided copper wire layer 8 is connected to the ground wire 3. The outer sheath 10 is then integrally encapsulated and sealed. Specifically, in the process of sealing the outer sheath 10, the peeling area may be re-injected and potted so that the injection potting area is equal in diameter to other parts of the substrate cable, and finally the outermost outer layer is sealed to The molded outer sheath 10 is finally formed.

通过上述制作过程可以看出，整个电源信号复合缆需要对剥离区进行重新注塑灌封，在实际的操作过程中，注塑灌封连接的部位存在连接不稳定的问题，进而会导致电源信号复合缆所受到的拉力被上述线缆(即第一信号线5、第二信号线6、火线2和地线3)的内芯承受，最终使得注塑灌封连接处的内芯容易断开。为此，本发明实施例一提供的电源信号复合缆的基材线缆外护套1至少为两层。在剥离的过程中，至少两层的基材线缆外护套1可以剥离不同的长度，进而使得基材线缆的剥离端面为阶梯状端面。阶梯状端面能够提高注塑灌封的灌封面积，进而提高注塑灌封的质量，最终能够提高封塑外护套10与基材线缆的结合力，进而解决注塑灌封连接部位存在的连接不稳定问题。Through the above manufacturing process, it can be seen that the entire power signal composite cable needs to be re-injected and potted to the stripping zone. In the actual operation process, the connection of the injection-molding joint has a problem of unstable connection, which in turn leads to a power signal composite cable. The tensile force received is received by the inner cores of the above-mentioned cables (i.e., the first signal line 5, the second signal line 6, the live line 2, and the ground line 3), and finally the inner core of the injection potting joint is easily broken. To this end, the base cable outer sheath 1 of the power signal composite cable provided by the first embodiment of the present invention has at least two layers. During the stripping process, at least two layers of the substrate cable outer sheath 1 can be peeled off to different lengths, so that the peeled end surface of the substrate cable is a stepped end surface. The stepped end face can improve the potting area of the injection potting, thereby improving the quality of the injection potting, and finally can improve the bonding force of the outer sheath 10 and the substrate cable, thereby solving the connection of the injection molding and sealing joint. Stable problem.

为进一步提高电源信号复合缆注塑灌封的可靠性，本实施例一提供的电源信号复合缆中，在自外向内的方向上，至少一层基材线缆外护套1的外表面可以设置有用于增大注塑灌封结合力的纹理。例如螺纹纹理、网格纹理等。当然，上述基材线缆外护套1还可以设置其它形状的纹理以增大注塑灌封的结合力，本实施例一不对纹理的形状作限制。In order to further improve the reliability of the injection molding and potting of the power signal composite cable, in the power signal composite cable provided in the first embodiment, the outer surface of the outer sheath 1 of at least one layer of the substrate cable may be disposed in the direction from the outside to the inside. There is a texture for increasing the bonding strength of the injection potting. Such as thread texture, mesh texture, etc. Of course, the above-mentioned substrate cable outer sheath 1 can also be provided with other shapes of texture to increase the bonding force of the injection potting. The first embodiment does not limit the shape of the texture.

本实施例一提供的电源信号复合缆中，自外向内的方向上，位于第二层的基材线缆外护套1的外表面上具有用于增大注塑灌封结合力的凸起，相比于纹理而言，在注塑灌封的过程中，凸起能够起到更为有效的连接作用，进一步提高电源信号复合缆注塑灌封的可靠性。更为优选的，上述凸起沿着基材线缆的横截面方向(即径向)上高度不等，能够在不同的注塑灌封层面上起到衔接作用。In the power signal composite cable provided in the first embodiment, in the outward-inward direction, the outer surface of the outer cable sheath 1 of the second layer has a protrusion for increasing the bonding force of the injection potting. Compared with the texture, in the process of injection potting, the protrusion can play a more effective connection, further improving the reliability of the power signal composite cable injection potting. More preferably, the protrusions are unequal in height along the cross-sectional direction (i.e., radial direction) of the substrate cable, and are capable of engaging on different injection potting layers.

由于电源信号复合缆在使用的过程中会受到磨损，可以通过增大电源信号复合缆的外护套(包括基材线缆外护套1和封塑外护套10)的硬度以降低磨损，但是这会使得整个电源信号复合缆的硬度较大，不利于布线操作。为了解决此问题，基材线缆外护套1和封塑外护套所组成的多层外护套中，在自外向内的方向上，每层外护套的硬度逐渐降低。此种硬度分布，使得电源信号复合缆的最外层外护套(即封塑外护套10)的硬度最高，能够有效地抵抗磨损，同时内层的外护套较软，使得整个电源信号复合缆的硬度又不至于过高，进而方便布线操作。同时，上述最外层外护套的硬度最高，能够较好地保持电源信号复合缆的线缆形态，便于后续接续封塑操作。Since the power signal composite cable is subject to wear during use, it can be increased by increasing the power signal. The hardness of the outer sheath of the cable (including the outer sheath of the base cable 1 and the outer sheath of the outer sheath 10) is reduced to reduce wear, but this causes the hardness of the entire power signal composite cable to be large, which is disadvantageous for wiring operations. In order to solve this problem, in the multilayer outer sheath composed of the outer sheath 1 of the base cable and the outer sheath of the outer sheath, the hardness of each outer sheath gradually decreases in the direction from the outer to the inner. The hardness distribution makes the outermost outer sheath of the power signal composite cable (ie, the outer sheath 10 of the seal) have the highest hardness, can effectively resist wear, and the outer sheath of the inner layer is soft, so that the entire power signal The hardness of the composite cable is not too high, which facilitates the wiring operation. At the same time, the outermost outer sheath has the highest hardness, and can better maintain the cable shape of the power signal composite cable, and is convenient for subsequent sealing and sealing operations.

上述电源信号复合缆的多层外护套中，在自外向内的方向上，每层外护套的硬度逐渐降低，最外层的外护套的硬度最高，这会增大电源信号复合缆制作时的剥线难度。为了解决此问题，本实施例一提供的电源信号复合缆在自外向内的方向上，每层外护套的厚度逐渐增大。该种结构使得同等外径的电源信号复合缆的前提下，最外层需要剥离长度较大的外护套的厚度最小，以降低剥线难度。当然，即便不在上述硬度或阶梯状剥离端的制约下，最外层外护套的厚度最小，也能够降低剥线难度，进而便于操作人员操作。In the multi-layer outer sheath of the above-mentioned power signal composite cable, the hardness of each outer sheath gradually decreases in the direction from the outer to the inner side, and the outer outer sheath has the highest hardness, which increases the power signal composite cable. Difficulty in stripping at the time of production. In order to solve this problem, in the direction of the outer-inward direction of the power signal composite cable provided in the first embodiment, the thickness of each outer sheath gradually increases. This kind of structure makes the thickness of the outer sheath of the outermost layer requiring a large peeling length to minimize the stripping difficulty under the premise of the power signal composite cable of the same outer diameter. Of course, even if the thickness of the outermost outer sheath is the smallest under the constraint of the above-mentioned hardness or stepped peeling end, the difficulty of stripping can be reduced, thereby facilitating the operation of the operator.

本实施例一提供的电源信号复合缆还包括加强筋，加强筋的设置能够提高整个电源信号复合缆的抗拉性能。优选的，加强筋可以为一条，一条加强筋穿过任一象限区域，第一信号线5、第二信号线6、火线2和地线3分布在加强筋的周围。更为优选的，加强筋可以为多条，多条加强筋可以离散分布在各个象限区域内。加强筋可以采用聚酯带、锡箔带、芳纶丝、玻璃纤维丝等材料制成。优选的，加强筋也可以包括加强内芯和包覆于加强内芯外的绝缘护套，加强内芯主要起到抗拉的作用，绝缘护套用于阻电，同时能够保证整个电源信号复合缆具有一定的柔韧性。加强内芯可以为单芯或多芯钢丝，保证抗拉的同时，钢丝也能使得整个光电复合缆具有一定的柔韧性。当然，上述加强筋的加强内芯也可以由非金属材质制作，本实施例一不限制加强内芯的材质。The power signal composite cable provided in the first embodiment further includes a reinforcing rib, and the arrangement of the reinforcing ribs can improve the tensile performance of the composite cable of the entire power signal. Preferably, the reinforcing ribs may be one piece, and one reinforcing rib passes through any quadrant area, and the first signal line 5, the second signal line 6, the hot line 2 and the ground line 3 are distributed around the reinforcing ribs. More preferably, the reinforcing ribs may be a plurality of ribs, and the plurality of reinforcing ribs may be discretely distributed in each quadrant region. The ribs can be made of polyester tape, tin foil tape, aramid wire, glass fiber wire and the like. Preferably, the reinforcing rib may also include an inner core and an insulating sheath coated on the outer core of the reinforcing inner core. The reinforcing inner core mainly serves as a tensile force, and the insulating sheath is used for blocking electricity, and at the same time, the entire power signal can be composited. The cable has a certain flexibility. The reinforcing inner core can be a single-core or multi-core steel wire to ensure tensile strength while the steel wire can also make the entire photoelectric composite cable have certain flexibility. Of course, the reinforcing core of the above rib can also be made of a non-metal material, and the first embodiment does not limit the material of the reinforcing core.

The resulting wiring reliability is reduced.

The power signal composite cable does not require additional fixtures and space, so that the cross node device 7 does not need to be limited by the fixture and space during the movement, and the operator can fine tune the method by bending or coiling the power signal composite cable. The location of the cross node device 7. It can be seen that the power signal composite cable provided in the second embodiment facilitates the adjustment of the position of the external device, so that the setting and the change of the location of the external device are flexible, and the space can be reduced.

同时，操作人员通过操作电源信号复合缆整体来调整十字节点设备7的位置，便于局部布线的优化，以达到更好的使用效果。本实施例二中，十字节点设备7可以形成于电源信号复合缆的任意位置，现场施工人员可以根据具体的施工环境合理地确定十字节点设备7的布设位置，进而适用于各种复杂的现场接线环境，降低布线难度。At the same time, the operator adjusts the position of the cross node device 7 by operating the power signal composite cable as a whole to facilitate the optimization of the local wiring to achieve a better use effect. In the second embodiment, the cross node device 7 can be formed at any position of the power signal composite cable, and the on-site construction personnel can reasonably determine the layout position of the cross node device 7 according to the specific construction environment, and is applicable to various complicated field wirings. Environment, reducing wiring difficulty.

综上可知，本实施例二提供的电源信号复合缆能够使得整个综合布线***具有足够的柔性。In summary, the power signal composite cable provided in the second embodiment can make the entire integrated wiring system have sufficient flexibility.

本实施例二提供的电源信号复合缆中，第一信号线5、第二信号线6、火线2和地线3中，任意两者的外径之差较小。优选的，上述任意两条线缆外径之差可以小于1mm。这使得火线2、地线3、第一信号线5和第二信号线6的直径较为均衡，进而当整个电源信号复合缆受到外力时，第一信号线5、第二信号线6、地线3和火线2的受力较为均匀，能够避免第一信号线5、第二信号线6、地线3和火线2由于尺寸差异较大造成的应力集中问题，能够解决各个线缆与十字节点设备7连接后由不均衡的内应力引起的接线可靠性降低问题。更为优选的，火线2、地线3、第一信号线5和第二信号线6的外径可以相等，以进一步缓解应力集中。In the power signal composite cable provided in the second embodiment, the difference between the outer diameters of any two of the first signal line 5, the second signal line 6, the live line 2, and the ground line 3 is small. Preferably, the difference between the outer diameters of any two of the above cables may be less than 1 mm. This makes the diameters of the live wire 2, the ground wire 3, the first signal line 5, and the second signal line 6 relatively balanced, and then the first signal line 5, the second signal line 6, and the ground line when the entire power signal composite cable receives an external force. 3 and the fire line 2 is more evenly stressed, and can avoid the stress concentration problem caused by the large difference in size between the first signal line 5, the second signal line 6, the ground line 3, and the live line 2, and can solve each cable and cross node device. 7 The problem of reduced wiring reliability caused by unbalanced internal stress after connection. More preferably, the outer diameters of the live wire 2, the ground wire 3, the first signal line 5, and the second signal line 6 may be equal to further alleviate stress concentration.

本实施例二提供的十字节点设备7可以包括第一PCB(Printed Circuit Board，印刷电路板)和第二PCB，第一PCB和第二PCB形成十字形结构。第一PCB和第二PCB上设置有使得十字节点设备7发挥其特定功能的电子元器件。第一PCB和第二PCB可以通过多种方式形成十字节点设备7的十字形结构，例如通过连接件或连接结构连接。第一PCB和第二PCB形成十字形结构，能够大大提高十字节点设备7的抗扭性能，进而能够有效防止在扭力存在时第一PCB和第二PCB上元器件脱落，从而能够提高十字节点设备7在实际应用中的可靠性。The cross node device 7 provided in the second embodiment may include a first PCB (Printed Circuit Board) and a second PCB, and the first PCB and the second PCB form a cross structure. The first PCB and the second PCB are provided with electronic components that cause the cross node device 7 to perform its specific function. The first PCB and the second PCB may form a cross-shaped structure of the cross-node device 7 in various ways, such as by a connector or a connection structure. The first PCB and the second PCB form a cross-shaped structure, which can greatly improve the torsional resistance of the cross node device 7, thereby effectively preventing the components on the first PCB and the second PCB from falling off when the torque is present, thereby improving the cross node device. 7 Reliability in practical applications.

同时，第一PCB和第二PCB形成的十字形空间结构使得两块PCB的两面均可以作为电子元器件安装面。这能够增加电子元器件的可安装位置，最终能够提高第一PCB和第二PCB的空间利用率。At the same time, the cross-shaped space structure formed by the first PCB and the second PCB enables both sides of the two PCBs to serve as mounting faces for the electronic components. This can increase the mountable position of the electronic components and ultimately improve the space utilization of the first PCB and the second PCB.

具体的，第一PCB和第二PCB可以通过卡接相连。第一PCB上设置有第一连接部位，第二PCB上设置有第二连接部位。第一连接部位和第二连接部位卡接，以使得第一PCB和第二PCB相连而形成十字形结构。Specifically, the first PCB and the second PCB may be connected by a card. The first PCB is provided with a first connection portion, and the second PCB is provided with a second connection portion. The first connecting portion and the second connecting portion are engaged, The cross-shaped structure is formed by connecting the first PCB and the second PCB.

在实际的应用过程中，第一PCB和第二PCB通过卡接的连接方式，可能不足以满足第一PCB和第二PCB之间的稳固性及实用性。为此，十字焊接焊点13(如图11所示)可以通过锡焊焊接在第一PCB和第二PCB的卡接处，进而起到辅助连接第一PCB和第二PCB的作用。第一PCB和第二PCB之间可能具有多个卡接部位，多个卡接部位分别位于十字节点设备7的不同部位。优选的，每个卡接部位均设置有十字焊接焊点，以进一步提高十字节点设备7结构的稳固性和实用性。十字焊接焊点13可以设置在第一PCB和第二PCB卡接处，还可以设置在第一PCB和第二PCB除卡接处之外的其它部位，以进一步提高第一PCB和第二PCB连接的稳固性。In the actual application process, the connection manner of the first PCB and the second PCB through the card connection may not be sufficient to satisfy the stability and practicability between the first PCB and the second PCB. To this end, the cross solder joint 13 (shown in FIG. 11) can be soldered to the junction of the first PCB and the second PCB, thereby functioning to assist in connecting the first PCB and the second PCB. There may be a plurality of latching portions between the first PCB and the second PCB, and the plurality of latching portions are respectively located at different portions of the cross node device 7. Preferably, each of the engaging portions is provided with a cross solder joint to further improve the stability and practicability of the structure of the cross node device 7. The cross solder joint 13 may be disposed at the first PCB and the second PCB, and may also be disposed at other portions of the first PCB and the second PCB except the card to further improve the first PCB and the second PCB The stability of the connection.

在连接线缆的过程中，第一信号线5、第二信号线6、火线2和地线3分别与位于不同象限区域内的相应部位的十字焊接焊点13焊接。十字焊接焊点13能够增加抗拉力，进而避免第一PCB和第二PCB上焊盘脱落或线缆脱落，能够增强连接的稳定性。In the process of connecting the cables, the first signal line 5, the second signal line 6, the live line 2, and the ground line 3 are respectively soldered to the cross solder joints 13 of the respective portions located in different quadrant regions. The cross-weld solder joint 13 can increase the tensile force, thereby preventing the pads on the first PCB and the second PCB from falling off or the cables from falling off, which can enhance the stability of the connection.

十字焊接焊点在第一PCB和第二PCB均形成如图5中所示的受锡面(即第一受锡面和第二受锡面)，即形成双面受锡。这种十字焊接焊点形成方式能够提高十字焊接焊点与线缆(即第一信号线5、第二信号线6、火线2和地线3)的焊接强度，进而提高十字节点设备7，甚至整个电源信号复合缆的抗拉抗扭性能。The cross-welded solder joint forms a tin-receiving surface (ie, a first tin-receiving surface and a second tin-receiving surface) as shown in FIG. 5 on both the first PCB and the second PCB, that is, a double-sided tin-forming layer is formed. The cross solder joint forming method can improve the welding strength of the cross solder joints and the cables (ie, the first signal line 5, the second signal line 6, the hot line 2, and the ground line 3), thereby improving the cross node device 7, and even The tensile and torsional properties of the entire power signal composite cable.

其中，第一连接部件和第二连接部件有多种不同的实现方式。如图6-图8，第一PCB21和第二PCB22可以采用竖插的卡接方式以形成十字形结构。具体的，第一PCB21上的第一连接部位可以设置为凸起形式，称为凸起部位。为了实现与第一PCB21上的凸起部位卡接，相对应的，第二PCB22上的第二连接部位可以设置为开孔形式，称为开孔部位。第一PCB21和第二PCB22通过凸起部位和开孔部位卡接相连。There are a plurality of different implementations of the first connecting member and the second connecting member. As shown in FIGS. 6-8, the first PCB 21 and the second PCB 22 may be vertically inserted to form a cross-shaped structure. Specifically, the first connection portion on the first PCB 21 may be disposed in a convex form, which is called a convex portion. In order to achieve the engagement with the convex portion on the first PCB 21, correspondingly, the second connection portion on the second PCB 22 may be provided in the form of an opening, which is called an opening portion. The first PCB 21 and the second PCB 22 are connected by a convex portion and an opening portion.

通常情况下，第一PCB21上的凸起部位可以至少为一个，第二PCB22上的开孔部位的数目应大于或等于凸起部位数目。当开孔部位的数目大于凸起部位的数目时，可以在第二PCB22卡接第一PCB21的同时，卡接其它的PCB，以最终形成十字形结构。Generally, the number of the convex portions on the first PCB 21 may be at least one, and the number of the opening portions on the second PCB 22 should be greater than or equal to the number of the convex portions. When the number of the opening portions is larger than the number of the protruding portions, the other PCBs may be snapped while the second PCB 22 is snapped onto the first PCB 21 to finally form a cross-shaped structure.

本实施例二的一个具体实施方式中，凸起部位211为一个，开孔部位221也仅为一个。需要说明的是，当凸起部位211仅为一个时，为了保证与第二PCB22卡接时的稳固性，优选应将该凸起部位211设置于所述第一PCB21的长度方向的中间位置。相应地，设置在第二PCB22上的唯一一个开孔部位221适应性设置于第二PCB22的长度方向的中间位置。图6所示的第一PCB21与图7所示的第二PCB22卡接在一起所形成的十字节点设备如图8所示。具体地，将第一PCB21上的凸起部位211***第二PCB22的开孔部位221，即形成十字节点设备。为了提高稳固性及实用性，可以用焊锡焊接第一PCB21和第二PCB22的卡接部位，形成十字焊接焊点，并将第一PCB21和第二PCB22固定。设置在第一PCB21和第二PCB22卡接部位的十字焊接焊点可参照图4中所示的十字焊接焊点4。In a specific embodiment of the second embodiment, the convex portion 211 is one, and the opening portion 221 is only one. It should be noted that when the convex portion 211 is only one, in order to ensure the stability when the second PCB 22 is engaged, the convex portion 211 should preferably be disposed at an intermediate position in the longitudinal direction of the first PCB 21. Correspondingly, the only one opening portion 221 disposed on the second PCB 22 is adaptively disposed at an intermediate position in the longitudinal direction of the second PCB 22. The cross node device formed by the first PCB 21 shown in FIG. 6 and the second PCB 22 shown in FIG. 7 is connected as shown in FIG. 8. Specifically, the convex portion 211 on the first PCB 21 is inserted into the opening portion 221 of the second PCB 22, that is, a cross node device is formed. To mention High stability and practicability, the soldering joints of the first PCB 21 and the second PCB 22 can be soldered to form a cross solder joint, and the first PCB 21 and the second PCB 22 are fixed. The cross solder joints disposed at the joint portions of the first PCB 21 and the second PCB 22 may be referred to the cross solder joint 4 shown in FIG.

请参考附图9-11，优选的，凸起部位为两个，开孔部位也为两个。请参考图9，当凸起部位311为两个时，为了提高卡接稳固性，两个凸起部位311分别位于第一PCB31长度方向的两端。相应的，如图10所示，两个开孔部位321适应性地设置于第二PCB32长度方向的两端。图9所示的第一PCB31与图10所示的第二PCB32卡接形成的十字节点设备7如图11所示。具体地，将第一PCB31上的两个凸起部位7***第二PCB32的两个开孔部位321，即形成十字形结构。为了提高稳固性及实用性，可以用焊锡焊接第一PCB31和第二PCB32形成的十字卡接部位，形成十字焊接焊点13(如图11所示)，并将两块PCB固定。同样，设置在第一PCB31和第二PCB32之间卡接部位的十字焊接焊点13可以参照图2中所示的十字焊接焊点4。Referring to Figures 9-11, preferably, there are two raised portions and two open holes. Referring to FIG. 9, when the convex portions 311 are two, in order to improve the fastening stability, the two convex portions 311 are respectively located at both ends of the first PCB 31 in the longitudinal direction. Correspondingly, as shown in FIG. 10, the two opening portions 321 are adaptively disposed at both ends of the second PCB 32 in the longitudinal direction. The cross node device 7 formed by the first PCB 31 shown in FIG. 9 being engaged with the second PCB 32 shown in FIG. 10 is as shown in FIG. Specifically, the two convex portions 7 on the first PCB 31 are inserted into the two opening portions 321 of the second PCB 32, that is, a cross-shaped structure is formed. In order to improve the stability and practicability, the cross-bonded portions formed by the first PCB 31 and the second PCB 32 may be solder-welded to form a cross-welded solder joint 13 (as shown in FIG. 11), and the two PCBs may be fixed. Similarly, the cross solder joint 13 disposed at the carding portion between the first PCB 31 and the second PCB 32 can be referred to the cross solder joint 4 shown in FIG.

各个线缆与十字焊接焊点焊接的过程中，线缆需要去掉外皮使其暴露出的内芯与十字焊接焊点焊接。为了避免位于十字节点设备7同一端的线缆之间由于内芯暴露而出现接触短路，上述十字焊接焊点的位置不能太靠近第一PCB和第二PCB的端面，如第一PCB和第二PCB的左端或右端，以使得十字形结构能够将各个线缆暴露的内芯隔离开。优选的，十字焊接焊点距离第一PCB和第二PCB的端部预设距离。本领域技术人员可以根据实际操作过程中线缆的内芯暴露长度来设定预设距离的大小，通常预设距离的大小为经验值。During the welding of each cable to the cross-welded solder joint, the cable needs to be removed from the outer skin to weld the exposed inner core to the cross-welded solder joint. In order to avoid a contact short circuit between the cables at the same end of the cross node device 7 due to the inner core exposure, the position of the cross solder joint cannot be too close to the end faces of the first PCB and the second PCB, such as the first PCB and the second PCB. The left or right end is such that the cross-shaped structure is capable of isolating the exposed core of each cable. Preferably, the cross solder joint is at a predetermined distance from the ends of the first PCB and the second PCB. A person skilled in the art can set the preset distance according to the inner core exposure length of the cable during the actual operation, and the preset distance is usually an empirical value.

本实施例二中，第一PCB和第二PCB的长度可以相等，也可以不等。优选的，第一PCB和第二PCB的长度相等。另外，第一PCB和第二PCB的长度越短，越有利于使得整个电源信号复合缆的回弯半径满足布线要求，也有利于提高整个电源信号复合缆的抗扭性能。当第一PCB和第二PCB的长度和宽度分别保持一致时，形成的十字节点设备更有利于优先注塑成圆柱体A(如图1所示)，然后再继续注塑以形成封塑外护套10。In the second embodiment, the lengths of the first PCB and the second PCB may be equal or different. Preferably, the first PCB and the second PCB are of equal length. In addition, the shorter the length of the first PCB and the second PCB, the more favorable the loopback radius of the entire power signal composite cable satisfies the wiring requirements, and also helps to improve the torsional performance of the entire power signal composite cable. When the length and width of the first PCB and the second PCB are respectively consistent, the formed cross node device is more advantageous for preferential injection molding into the cylinder A (as shown in FIG. 1), and then continues to be injection molded to form a sealed outer sheath. 10.

此外，第一PCB和第二PCB均具有一定厚度，优选的，第一PCB和第二PCB的厚度相等，也能够提高十字节点设备7的抗扭性。具体的，第一PCB和第二PCB可为单层板或多层板。In addition, both the first PCB and the second PCB have a certain thickness. Preferably, the thicknesses of the first PCB and the second PCB are equal, and the torsion resistance of the cross node device 7 can also be improved. Specifically, the first PCB and the second PCB may be a single layer board or a multi-layer board.

目前，电源信号复合缆中，第一信号线5、第二信号线6、火线2和地线3为普通的集束结构，这种电源信号复合缆在与十字节点设备7相连时容易产生旋钮，进而使得第一信号线5、第二信号线6、火线2和地线3产生较大的扭力，进而造成电源信号复合缆中的各个线缆的接头处于旋钮绷紧状态。这种状态会导致地线3、火线2、第一信号线5、第二信号线6处于离散状态，最终导致电源信号复合缆的端部接线困难。为了解决此问题，本实施例二提供的电源信号复合缆中，地线3、火线2、第一信号线5和第二信号线6沿着电源信号复合缆的中轴线层绞分布。第一信号线5、第二信号线6、火线2和地线3采用层绞分布的方式，使得整个电源信号复合缆在遭受扭力时本身就具有顺着扭力方向恢复的作用力，这最终会降低扭力对各个线缆的影响，进而解决电源信号复合缆的端部接线困难的问题。At present, in the power signal composite cable, the first signal line 5, the second signal line 6, the live line 2, and the ground line 3 are ordinary bundle structures, and the power signal composite cable is easy to generate a knob when connected to the cross node device 7. Further, the first signal line 5, the second signal line 6, the live line 2, and the ground line 3 generate a large torque, thereby causing the joints of the respective cables in the power signal composite cable to be in a knob tension state. This state causes the ground line 3, the live line 2, the first signal line 5, and the second signal line 6 to be in a discrete state, which ultimately causes difficulty in wiring the end portion of the power signal composite cable. In order to solve this problem, the power signal composite cable provided in the second embodiment The ground line 3, the live line 2, the first signal line 5 and the second signal line 6 are distributed along the central axis of the power signal composite cable. The first signal line 5, the second signal line 6, the live line 2 and the ground line 3 are distributed in a layered manner, so that the entire power signal composite cable itself has a force to recover in the direction of the torsion when subjected to the torsion force, which will eventually Reduce the impact of torque on each cable, and then solve the problem of difficult wiring at the end of the power signal composite cable.

更为优选的，本实施例二提供的电源信号复合缆还包括屏蔽层，用于屏蔽外接电磁信号对第一信号线5和第二信号线6的影响。屏蔽层依附于基材线缆外护套1内，且包覆于第一信号线5、第二信号线6、火线2和地线3所形成的线缆束上。在十字节点设备7与第一信号线5、第二信号线6、火线2和地线3连接后，屏蔽层再与与地线3相连，用于将外界电磁干扰信号接地，这能够较好地消除外界电磁干扰信号。具体的，请再次参考附图3，屏蔽层包括位于外层的编织铜丝层8和位于内层的绕包带层9，绕包带层9贴附于编织铜丝层8之内，用于裹紧线缆束。在十字节点设备7与第一信号线5、第二信号线6、火线2和地线3相连后，编织铜丝层8再与地线3相连，用于将外界电磁干扰信号接地，即消除外接电磁干扰信号。具体的，编织铜丝层8可以为编织铜丝网。绕包带层9可以为聚脂薄膜绕包带层或半导体绕包带层。More preferably, the power signal composite cable provided in the second embodiment further includes a shielding layer for shielding the influence of the external electromagnetic signal on the first signal line 5 and the second signal line 6. The shielding layer is attached to the outer sheath 1 of the substrate cable and covered on the cable bundle formed by the first signal line 5, the second signal line 6, the live line 2 and the ground line 3. After the cross node device 7 is connected to the first signal line 5, the second signal line 6, the live line 2 and the ground line 3, the shielding layer is connected to the ground line 3 for grounding the external electromagnetic interference signal, which is better. Ground to eliminate external electromagnetic interference signals. Specifically, referring again to FIG. 3, the shielding layer includes a braided copper wire layer 8 on the outer layer and a wrapping tape layer 9 on the inner layer, and the wrapping tape layer 9 is attached to the braided copper wire layer 8 for use. Tighten the cable bundle. After the cross node device 7 is connected to the first signal line 5, the second signal line 6, the live line 2 and the ground line 3, the braided copper wire layer 8 is connected to the ground line 3 for grounding the external electromagnetic interference signal, that is, eliminating External electromagnetic interference signal. Specifically, the braided copper wire layer 8 may be a braided copper wire mesh. The wrapping tape layer 9 may be a polyester film wrapping tape layer or a semiconductor wrapping tape layer.

十字节点设备7为十字形结构，第一信号线5、第二信号线6、火线2和地线3分别位于十字形结构的四个象限内，进而使得第一信号线5、第二信号线6、火线2和地线3呈十字状分布，这种分布方式使得电源信号复合缆的结构更加稳定，能够进一步避免应力集中。另外，十字节点设备7起到较好的支撑作用，使得整个电源信号复合缆强度增加和抗扭力效果更好，同时能够避免第一PCB和第二PCB上的电子元器件由于受扭力而脱落。The cross node device 7 has a cross-shaped structure, and the first signal line 5, the second signal line 6, the live line 2, and the ground line 3 are respectively located in four quadrants of the cross-shaped structure, thereby making the first signal line 5 and the second signal line 6. The fire line 2 and the ground line 3 are distributed in a cross shape. This distribution mode makes the structure of the power signal composite cable more stable, and can further avoid stress concentration. In addition, the cross node device 7 plays a better supporting role, so that the strength of the entire power signal composite cable is increased and the torsion resistance effect is better, and the electronic components on the first PCB and the second PCB can be prevented from falling off due to the torsion.

请再次参考附图1，本发明实施例二提供的更为优选的电源信号复合缆的制作过程如下：以基材线缆(指的是未添加十字节点设备7和一体式封塑阻燃外护套10)为操作对象，操作人员剥除两段基材线缆连接端的部分基材线缆外护套1和剥离连接端编织铜丝层8，然后去除绕包带层9，用剥线钳分别去除第一信号线5、第二信号线6、火线2和地线3的外皮，把相连两段第一信号线5、第二信号线6、火线2和地线3的剥离端分别通过十字节点设备四个象限区域内的十字焊接焊点相连，使各个线缆分布在各自对应的象限区域内。然后，将编织铜丝层8与地线3相连。再然后整体注塑灌封封塑外护套10。具体的，在封塑外护套10的过程中，可以先将剥离区域重新注塑灌封，使得注塑灌封区域与基材线缆的其它部位直径相等，最后在整体最外层封塑，以最终形成封塑外护套10。Referring to FIG. 1 again, the manufacturing process of the more preferred power signal composite cable provided by the second embodiment of the present invention is as follows: the substrate cable (refers to the non-added cross node device 7 and the integrated sealing flame retardant) The sheath 10) is an operation object, and the operator peels off part of the substrate cable outer sheath 1 and the peeling connection end braided copper wire layer 8 of the two-stage substrate cable connection end, and then removes the wrapping tape layer 9 and respectively uses a wire stripper The outer skins of the first signal line 5, the second signal line 6, the live line 2, and the ground line 3 are removed, and the stripped ends of the first two lines of the first signal line 5, the second signal line 6, the hot line 2, and the ground line 3 are respectively passed through the cross. The cross solder joints in the four quadrant regions of the node device are connected such that the respective cables are distributed in respective corresponding quadrant regions. Then, the braided copper wire layer 8 is connected to the ground wire 3. The outer sheath 10 is then integrally encapsulated and sealed. Specifically, in the process of sealing the outer sheath 10, the peeling area may be re-injected and potted so that the injection potting area is equal in diameter to other parts of the substrate cable, and finally the outermost outer layer is sealed to The molded outer sheath 10 is finally formed.

通过上述制作过程可以看出，整个电源信号复合缆需要对剥离区进行重新注塑灌封，在实际的操作过程中，注塑灌封连接的部位存在连接不稳定的问题，进而会导致电源信号复合缆所受到的拉力被上述线缆(即第一信号线5、第二信号线6、火线2和地线3)的内芯承受，最终使得注塑灌封连接处的内芯容易断开。为此，本发明实施例二提供的电源信号复合缆的基材线缆外护套1至少为两层。在剥离的过程中，至少两层的基材线缆外护套1可以剥离不同的长度，进而使得基材线缆的剥离端面为阶梯状端面。阶梯状端面能够提高注塑灌封的灌封面积，进而提高注塑灌封的质量，最终能够提高封塑外护套10与基材线缆的结合力，进而解决注塑灌封连接部位存在的连接不稳定问题。Through the above manufacturing process, it can be seen that the entire power signal composite cable needs to be re-injected and potted to the stripping zone. In the actual operation process, the connection of the injection-molding joint has a problem of unstable connection, which in turn leads to a power signal composite cable. The tension received is the above cable (ie, the first signal line 5, the second signal) The inner core of the wire 6, the fire wire 2 and the ground wire 3) is subjected to, and finally the inner core of the injection potting joint is easily broken. To this end, the base cable outer sheath 1 of the power signal composite cable provided by the second embodiment of the present invention has at least two layers. During the stripping process, at least two layers of the substrate cable outer sheath 1 can be peeled off to different lengths, so that the peeled end surface of the substrate cable is a stepped end surface. The stepped end face can improve the potting area of the injection potting, thereby improving the quality of the injection potting, and finally can improve the bonding force of the outer sheath 10 and the substrate cable, thereby solving the connection of the injection molding and sealing joint. Stable problem.

为进一步提高电源信号复合缆注塑灌封的可靠性，本实施例二提供的电源信号复合缆中，在自外向内的方向上，至少一层的基材线缆外护套1的外表面可以设置有用于增大注塑灌封结合力的纹理。例如螺纹纹理、网格纹理等。当然，上述基材线缆外护套1还可以设置其它形状的纹理以增大注塑灌封的结合力，本实施例二不对纹理的形状作限制。In order to further improve the reliability of the injection molding and potting of the power signal composite cable, in the power signal composite cable provided in the second embodiment, at least one layer of the outer surface of the outer sheath 1 of the substrate cable may be in the direction from the outside to the inside. A texture is provided for increasing the bonding strength of the injection potting. Such as thread texture, mesh texture, etc. Of course, the above-mentioned substrate cable outer sheath 1 can also be provided with other shapes of texture to increase the bonding force of the injection potting, and the second embodiment does not limit the shape of the texture.

本实施例二提供的电源信号复合缆中，自外向内的方向上，位于第二层的基材线缆外护套1的外表面上具有用于增大注塑灌封结合力的凸起，相比于纹理而言，在注塑灌封的过程中，凸起能够起到更为有效的连接作用，进一步提高电源信号复合缆注塑灌封的可靠性。更为优选的，上述凸起沿着基材线缆的横截面方向(即径向)上高度不等，能够在不同的注塑灌封层面上起到衔接作用。In the power signal composite cable provided in the second embodiment, in the direction from the outside to the inside, the outer surface of the outer sheath 1 of the substrate cable of the second layer has a protrusion for increasing the bonding force of the injection potting. Compared with the texture, in the process of injection potting, the protrusion can play a more effective connection, further improving the reliability of the power signal composite cable injection potting. More preferably, the protrusions are unequal in height along the cross-sectional direction (i.e., radial direction) of the substrate cable, and are capable of engaging on different injection potting layers.

由于电源信号复合缆在使用的过程中会受到磨损，可以通过增大电源信号复合缆的外护套(包括基材线缆外护套1和封塑外护套10)的硬度以降低磨损，但是这会使得整个电源信号复合缆的硬度较大，不利于布线操作。为了解决此问题，基材线缆外护套1和封塑外护套所组成的多层外护套中，在自外向内的方向上，每层外护套的硬度逐渐降低。此种硬度分布，使得电源信号复合缆的最外层外护套(即封塑外护套10)的硬度最高，能够有效地抵抗磨损，同时内层的外护套较软，使得整个电源信号复合缆的硬度又不至于过高，进而方便布线操作。同时，上述最外层外护套的硬度最高，能够较好地保持电源信号复合缆的线缆形态，便于后续接续封塑操作。Since the power signal composite cable is subject to wear during use, the wear of the outer sheath of the power signal composite cable (including the outer sheath of the substrate cable 1 and the outer sheath 10 of the plastic sheath) can be increased to reduce wear. However, this will make the overall power signal composite cable have a higher hardness, which is not conducive to the wiring operation. In order to solve this problem, in the multilayer outer sheath composed of the outer sheath 1 of the base cable and the outer sheath of the outer sheath, the hardness of each outer sheath gradually decreases in the direction from the outer to the inner. The hardness distribution makes the outermost outer sheath of the power signal composite cable (ie, the outer sheath 10 of the seal) have the highest hardness, can effectively resist wear, and the outer sheath of the inner layer is soft, so that the entire power signal The hardness of the composite cable is not too high, which facilitates the wiring operation. At the same time, the outermost outer sheath has the highest hardness, and can better maintain the cable shape of the power signal composite cable, and is convenient for subsequent sealing and sealing operations.

上述电源信号复合缆的多层外护套中，在自外向内的方向上，每层外护套的硬度逐渐降低，最外层的外护套的硬度最高，这会增大电源信号复合缆制作时的剥线难度。为了解决此问题，本实施例二提供的电源信号复合缆在自外向内的方向上，每层外护套1的厚度逐渐增大。该种结构使得同等外径的电源信号复合缆的前提下，最外层需要剥离长度较大的外护套的厚度最小，以降低剥线难度。当然，即便不在上述硬度或阶梯状剥离端的制约下，最外层外护套的厚度最小，也能够降低剥线难度，进而便于操作人员操作。In the multi-layer outer sheath of the above-mentioned power signal composite cable, the hardness of each outer sheath gradually decreases in the direction from the outer to the inner side, and the outer outer sheath has the highest hardness, which increases the power signal composite cable. Difficulty in stripping at the time of production. In order to solve this problem, the power signal composite cable provided in the second embodiment is gradually increased in thickness from the outer to the inner side. This kind of structure makes the thickness of the outer sheath of the outermost layer requiring a large peeling length to minimize the stripping difficulty under the premise of the power signal composite cable of the same outer diameter. Of course, even if the thickness of the outermost outer sheath is the smallest under the constraint of the above-mentioned hardness or stepped peeling end, the difficulty of stripping can be reduced, thereby facilitating the operation of the operator.

在实际的应用过程中，第一PCB和第二PCB通过卡接的连接方式，可能不足以满足第一PCB和第二PCB之间的稳固性及实用性。为此，十字焊接焊点可以通过锡焊焊接在第一PCB和第二PCB的卡接处，进而起到辅助连接第一PCB和第二PCB的作用。第一PCB和第二PCB之间可能具有多个卡接部位，多个卡接部位分别位于十字节点设备7的不同部位。优选的，每个卡接部位均设置有十字焊接焊点，以进一步提高十字节点设备7结构的稳固性和实用性。十字焊接焊点可以设置在第一PCB和第二PCB卡接处，还可以设置在第一PCB和第二PCB除卡接处之外的其它部位，以进一步提高第一PCB和第二PCB连接的稳固性。In the actual application process, the connection manner of the first PCB and the second PCB through the card connection may not be sufficient to satisfy the stability and practicability between the first PCB and the second PCB. To this end, the cross solder joint can be soldered to the junction of the first PCB and the second PCB, thereby functioning to assist in connecting the first PCB and the second PCB. There may be a plurality of latching portions between the first PCB and the second PCB, and the plurality of latching portions are respectively located at different portions of the cross node device 7. Preferably, each of the engaging portions is provided with a cross solder joint to further improve the stability and practicability of the structure of the cross node device 7.

本实施例三中，第一PCB和第二PCB的长度可以相等，也可以不等。优选的，第一PCB和第二PCB的长度相等。另外，第一PCB和第二PCB的长度越短，越有利于使得整个电源信号复合缆的回弯半径满足布线要求，也有利于提高整个电源信号复合缆的抗扭性能。当第一PCB和第二PCB的长度和宽度分别保持一致时，形成的十字节点设备更有利于优先注塑成圆柱体A(如图1所示)，然后再继续注塑以形成封塑外护套10。In the third embodiment, the lengths of the first PCB and the second PCB may be equal or different. Preferably, the first PCB and the second PCB are of equal length. In addition, the shorter the length of the first PCB and the second PCB, the more favorable the loopback radius of the entire power signal composite cable satisfies the wiring requirements, and also helps to improve the torsional performance of the entire power signal composite cable.

目前，电源信号复合缆中，第一信号线5、第二信号线6、火线2和地线3为普通的集束结构，这种电源信号复合缆在与十字节点设备7相连时容易产生旋钮，进而使得第一信号线5、第二信号线6、火线2和地线3产生较大的扭力，进而造成电源信号复合缆中的各个线缆的接头处于旋钮绷紧状态。这种状态会导致地线3、火线2、第一信号线5、第二信号线6处于离散状态，最终导致电源信号复合缆的端部接线困难。为了解决此问题，本实施例三提供的电源信号复合缆中，地线3、火线2、第一信号线5和第二信号线6沿着电源信号复合缆的中轴线层绞分布。第一信号线5、第二信号线6、火线2和地线3采用层绞分布的方式，使得整个电源信号复合缆在遭受扭力时本身就具有顺着扭力方向恢复的作用力，这最终会降低扭力对各个线缆的影响，进而解决电源信号复合缆的端部接线困难的问题。At present, in the power signal composite cable, the first signal line 5, the second signal line 6, the live line 2, and the ground line 3 are ordinary bundle structures, and the power signal composite cable is easy to generate a knob when connected to the cross node device 7. Further, the first signal line 5, the second signal line 6, the live line 2, and the ground line 3 generate a large torque, thereby causing the joints of the respective cables in the power signal composite cable to be in a knob tension state. This state causes the ground line 3, the live line 2, the first signal line 5, and the second signal line 6 to be in a discrete state, which ultimately causes difficulty in wiring the end portion of the power signal composite cable.

The shielding layer is attached to the outer sheath 1 of the substrate cable and covered on the cable bundle formed by the first signal line 5, the second signal line 6, the live line 2 and the ground line 3. After the cross node device 7 is connected to the first signal line 5, the second signal line 6, the live line 2 and the ground line 3, the shielding layer is connected to the ground line 3 for grounding the external electromagnetic interference signal, which can be better Eliminate external electromagnetic interference signals.

Tighten the cable bundle. After the cross node device 7 is connected to the first signal line 5, the second signal line 6, the live line 2 and the ground line 3, the braided copper wire layer 8 is connected to the ground line 3 for grounding the external electromagnetic interference signal, that is, eliminating External electromagnetic interference signal. Specifically, the braided copper wire layer 8 may be a braided copper wire mesh. The wrapping tape layer 9 may be a polyester film wrapping tape layer or a semiconductor wrapping tape layer.

十字节点设备7为十字形结构，第二信号线5、第二信号线6、火线2和地线3分别位于十字形结构的四个象限内，进而使得第一信号线5、第二信号线6、火线2和地线3呈十字状分布，这种分布方式使得电源信号复合缆的结构更加稳定，能够进一步避免应力集中。另外，十字节点设备7起到较好的支撑作用，使得整个电源信号复合缆强度增加和抗扭力效果更好，同时能够避免第一PCB和第二PCB上的电子元器件由于受扭力而脱落。The cross node device 7 is a cross-shaped structure, and the second signal line 5, the second signal line 6, the live line 2, and the ground line 3 are respectively located in four quadrants of the cross-shaped structure, thereby making the first signal line 5 and the second signal line 6. The fire line 2 and the ground line 3 are distributed in a cross shape. This distribution mode makes the structure of the power signal composite cable more stable, and can further avoid stress concentration. In addition, the cross node device 7 plays a better supporting role, so that the strength of the entire power signal composite cable is increased and the torsion resistance effect is better, and the electronic components on the first PCB and the second PCB can be prevented from falling off due to the torsion.

请再次参考附图1，本发明实施例三提供的更为优选的电源信号复合缆的制作过程如下：以基材线缆(指的是未添加十字节点设备7和一体式封塑阻燃外护套10)为操作对象，操作人员剥除两段基材线缆连接端的部分基材线缆外护套1，然后剥离编织铜丝层8，再然后去除绕包带层9，用剥线钳分别去除第一信号线5、第二信号线6、火线2和地线3的外皮，把相连两段第一信号线5、第二信号线6、火线2和地线3的剥离端分别通过十字节点设备四个象限区域内的十字焊接焊点相连，使各个线缆分布在各自对应的象限区域内。然后，将编织铜丝层8与地线3相连。再然后整体注塑灌封封塑外护套10。具体的，在封塑外护套10的过程中，可以先将剥离区域重新注塑灌封，使得注塑灌封区域与基材线缆的其它部位直径相等，最后在整体最外层封塑，以最终形成封塑外护套10。Referring to FIG. 1 again, a more preferred power signal composite cable provided by the third embodiment of the present invention is as follows: a substrate cable (refers to a non-added cross node device 7 and an integrated package flame retardant) The sheath 10) is an operation object, the operator peels off part of the substrate cable outer sheath 1 of the two-stage substrate cable connection end, and then peels off the braided copper wire layer 8, and then removes the wrapping tape layer 9, and respectively uses a wire stripper The outer skins of the first signal line 5, the second signal line 6, the live line 2, and the ground line 3 are removed, and the stripped ends of the first two lines of the first signal line 5, the second signal line 6, the hot line 2, and the ground line 3 are respectively passed through the cross. The cross solder joints in the four quadrant regions of the node device are connected such that the respective cables are distributed in respective corresponding quadrant regions. Then, the braided copper wire layer 8 is connected to the ground wire 3. The outer sheath 10 is then integrally encapsulated and sealed. Specifically, in the process of sealing the outer sheath 10, the peeling area may be re-injected and potted so that the injection potting area is equal in diameter to other parts of the substrate cable, and finally the outermost outer layer is sealed to The molded outer sheath 10 is finally formed.

通过上述制作过程可以看出，整个电源信号复合缆需要对剥离区进行重新注塑灌封，在实际的操作过程中，注塑灌封连接的部位存在连接不稳定的问题，进而会导致电源信号复合缆所受到的拉力被上述线缆(即第一信号线5、第二信号线6、火线2和地线3)的内芯承受，最终使得注塑灌封连接处的内芯容易断开。为此，本发明实施例三提供的电源信号复合缆的基材线缆外护套1至少为两层。在剥离的过程中，至少两层的基材线缆外护套1可以剥离不同的长度，进而使得基材线缆的剥离端面为阶梯状端面。阶梯状端面能够提高注塑灌封的灌封面积，进而提高注塑灌封的质量，最终能够提高封塑外护套10与基材线缆的结合力，进而解决解决注塑灌封连接部位存在的连接不稳定问题。Through the above manufacturing process, it can be seen that the entire power signal composite cable needs to be re-injected and potted to the stripping zone. In the actual operation process, the connection of the injection-molding joint has a problem of unstable connection, which in turn leads to a power signal composite cable. The tensile force received is received by the inner cores of the above-mentioned cables (i.e., the first signal line 5, the second signal line 6, the live line 2, and the ground line 3), and finally the inner core of the injection potting joint is easily broken. To this end, the base cable outer sheath 1 of the power signal composite cable provided by the third embodiment of the present invention has at least two layers. During the stripping process, at least two layers of the substrate cable outer sheath 1 can be peeled off different lengths, thereby The peeling end surface of the base material cable is a stepped end surface. The stepped end face can improve the potting area of the injection potting, thereby improving the quality of the injection potting, and finally improving the bonding force of the outer sheath 10 and the substrate cable, thereby solving the connection existing in the injection molding and sealing joint. Unstable problem.

为进一步提高电源信号复合缆注塑灌封的可靠性，本实施例三提供的电源信号复合缆中，在自外向内的方向上，至少一层的基材线缆外护套1的外表面可以设置有用于增大注塑灌封结合力的纹理。例如螺纹纹理、网格纹理等。当然，上述位于第二层的基材线缆外护套1还可以设置其它形状的纹理以增大注塑灌封的结合力，本实施例三不对纹理的形状作限制。In order to further improve the reliability of the injection molding and potting of the power signal composite cable, in the power signal composite cable provided in the third embodiment, at least one layer of the outer surface of the outer sheath 1 of the substrate cable may be in the direction from the outside to the inside. A texture is provided for increasing the bonding strength of the injection potting. Such as thread texture, mesh texture, etc. Of course, the above-mentioned substrate outer sheath 1 of the second layer may also be provided with other shapes of texture to increase the bonding force of the injection potting. The third embodiment does not limit the shape of the texture.

本实施例三提供的电源信号复合缆中，自外向内的方向上，位于第二层的基材线缆外护套1的外表面上具有用于增大注塑灌封结合力的凸起，相比于纹理而言，在注塑灌封的过程中，凸起能够起到更为有效的连接作用，进一步提高电源信号复合缆注塑灌封的可靠性。更为优选的，上述凸起沿着基材线缆的横截面方向(即径向)上高度不等，能够在不同的注塑灌封层面上起到衔接作用。In the power signal composite cable provided in the third embodiment, in the direction from the outside to the inside, the outer surface of the outer sheath 1 of the base cable of the second layer has a protrusion for increasing the bonding force of the injection potting. Compared with the texture, in the process of injection potting, the protrusion can play a more effective connection, further improving the reliability of the power signal composite cable injection potting. More preferably, the protrusions are unequal in height along the cross-sectional direction (i.e., radial direction) of the substrate cable, and are capable of engaging on different injection potting layers.

上述电源信号复合缆的多层外护套中，在自外向内的方向上，每层外护套的硬度逐渐降低，最外层的外护套的硬度最高，这会增大电源信号复合缆制作时的剥线难度。为了解决此问题，本实施例三提供的电源信号复合缆在自外向内的方向上，每层外护套1的厚度逐渐增大。该种结构使得同等外径的电源信号复合缆的前提下，最外层需要剥离长度较大的外护套的厚度最小，以降低剥线难度。当然，即便不在上述硬度或阶梯状剥离端的制约下，最外层外护套的厚度最小，也能够降低剥线难度，进而便于操作人员操作。In the multi-layer outer sheath of the above-mentioned power signal composite cable, the hardness of each outer sheath gradually decreases in the direction from the outer to the inner side, and the outer outer sheath has the highest hardness, which increases the power signal composite cable. Difficulty in stripping at the time of production. In order to solve this problem, in the direction from the outside to the inside of the power signal composite cable provided in the third embodiment, the thickness of each outer sheath 1 is gradually increased. This kind of structure makes the thickness of the outer sheath of the outermost layer requiring a large peeling length to minimize the stripping difficulty under the premise of the power signal composite cable of the same outer diameter. Of course, even if the thickness of the outermost outer sheath is the smallest under the constraint of the above-mentioned hardness or stepped peeling end, the difficulty of stripping can be reduced, thereby facilitating the operation of the operator.

本实施例三提供的电源信号复合缆还包括加强筋，加强筋的设置能够提高整个电源信号复合缆的抗拉性能。优选的，加强筋可以为一条，一条加强筋穿过任一象限区域，第一信号线5、第二信号线6、火线2和地线3分布在加强筋的周围。更为优选的，加强筋可以为多条，多条加强筋可以离散分布在各个象限区域内。加强筋可以采用聚酯带、锡箔带、芳纶丝、玻璃纤维丝等材料制成。优选的，加强筋也可以包括加强内芯和包覆于加强内芯外的绝缘护套，加强内芯主要起到抗拉的作用，绝缘护套用于阻电，同时能够保证整个电源信号复合缆具有一定的柔韧性。加强内芯可以为单芯或多芯钢丝，保证抗拉的同时，钢丝也能使得整个光电复合缆具有一定的柔韧性。当然，上述加强筋的加强内芯也可以由非金属材质制作，本实施例三不限制加强内芯的材质。The power signal composite cable provided in the third embodiment further includes a reinforcing rib, and the arrangement of the reinforcing ribs can improve the tensile performance of the composite cable of the entire power signal. Preferably, the reinforcing ribs may be one piece, and one reinforcing rib passes through any quadrant area, and the first signal line 5, the second signal line 6, the hot line 2 and the ground line 3 are distributed around the reinforcing ribs. More preferably, the reinforcing ribs may be a plurality of ribs, and the plurality of reinforcing ribs may be discretely distributed in each quadrant region. The ribs can be made of polyester tape, tin foil tape, aramid wire, glass fiber wire and the like. Preferably, the reinforcing rib may also include a reinforcing inner core and an insulating sheath coated on the outer core of the reinforcing inner core, and the reinforcing inner core mainly serves The role of tensile strength, the insulation sheath is used to block electricity, and at the same time, it can ensure the flexibility of the entire power signal composite cable. The reinforcing inner core can be a single-core or multi-core steel wire to ensure tensile strength while the steel wire can also make the entire photoelectric composite cable have certain flexibility. Of course, the reinforcing core of the above rib can also be made of a non-metal material, and the third embodiment does not limit the material of the reinforcing core.
