一种线缆保护壳及通信设备
相关申请的交叉引用
本申请要求在2019年08月15日提交中国专利局、申请号为201910753594.6、申请名称为“一种线缆保护壳及通信设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及到通信技术领域，尤其涉及到一种线缆保护壳及通信设备。
背景技术
现有的网络预连接安装大多是通过将光缆的连接头***到适配器中，将连接头旋转一定角度卡入适配器来完成光缆与适配器的连接，安装方便快捷，缩减了施工时间。但是，这种易安装方式同时也意味着易拆卸：沿反方向旋转即可拆出。这就带来了一些风险点，譬如由于错误操作拧出或者有意破坏拆卸而导致业务中断，同时还存在被盗风险。这些风险点对于需要挂墙安装或者使用在暴露环境中的接头盒、光纤分纤箱来说尤为严重。
现有防盗防拆卸的解决方案是使用一个保护罩将所有接头盒或者光纤分纤箱以及关联的连接头同时罩住，使得连接头在对外界面上不可见。这种整体防护方式虽能达到防盗防拆卸的作用，但是也很大程度上增加了盒体体积，影响美观。除此之外，保护罩需要根据不同的光缆及其排布进行定制，通用性极差。另外，当涉及到后续维护时，哪怕只有一个连接头需要维护，也需要打开整个保护罩，不仅带来了操作上的不便，还使得其余不需要维护的连接头也失去了保护，增加了误操作导致业务中断的风险。
发明内容
本申请提供了一种线缆保护壳及通信设备，用以在提高线缆的安全性时，方便维护。
第一方面，提供了一种线缆保护壳，该线缆保护壳包括：两个壳体，两个壳体相对设置，且所述两个壳体可拆卸的固定连接；在具体连接时，可以采用两个壳体的一侧转动连接，另一侧可拆卸的固定连接，也可以采用两侧均采用可拆卸的固定连接。此外，两个壳体的结构相近似，如每个壳体包括：第一凹槽以及与所述第一凹槽连通的第二凹槽，且所述第一凹槽远离所述第二凹槽的一端设置有用于卡装在线缆的限位凸起；在所述两个壳体固定连接时，两个所述第一凹槽围成用于容纳线缆接头的第一容纳腔体，且所述限位凸起用于限定所述线缆接头与所述第一容纳腔体的轴向滑动；两个所述第二凹槽围成容纳线缆安装头的第二容纳腔体。在上述技术方案中，通过限位凸起限定线缆保护壳的轴向运动方向，且在线缆保护壳套装在线缆接头及线缆安装头上时，线缆保护壳可相对线缆接头转动。而在线缆从线缆安装头中取下时，需要将线缆接头相对线缆安装头转动，而设置的线缆保护壳避免了直接拧动线缆接头，因此在线缆保护壳的保护下无法直接将线缆接头从线缆安装头中拧下来，提高了线缆的安全性。

在一个具体的可实施方案中，所述两个卡扣的卡钩相背。提高了卡扣与卡槽连接的稳定性。当然也可以采用两个卡扣的卡钩相同，同样可以提高卡扣与卡槽配合的稳定性。
在一个具体的可实施方案中，所述裙边结构设置有缺口。该缺口用于***工具撬开卡扣与卡槽。
在一个具体的可实施方案中，所述缺口位于所述两个卡扣之间。使得在撬开时，两个卡扣受力比较均衡。
在一个具体的可实施方案中，所述裙边结构设置有遮挡所述缺口的档板，且所述档板可相对所述裙边结构转动。提高了安全性。
在一个具体的可实施方案中，所述档板位于所述缺口内，且与所述裙边结构的侧面具有设定距离。方便工具***。

在一个具体的可实施方案中，每个线缆上套装有连接绳，所述连接绳与所述设备主体固定连接。进一步提高线缆的安全性。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。
为了方便理解，首先解释几个名词：
预制缆：一种带连接头的光缆，其中光缆的连接插头已在工厂预制成端，到施工现场后直接***到对应适配器上，可以实现即插即用。
光缆接头盒：光缆接头盒为支持人/手孔安装的户外型产品，主要应用于光接入网络的用户接入点，实现光缆接续以及用户端的入户光缆引入。
光纤分纤箱：光纤分纤箱位于光接入网络中的用户接入点，实现配线光缆和入户光缆的接续、光纤的直通、分歧和保护功能。
在本申请中下文中的线缆指代的即为上述的预制缆。该预制缆在使用时，可以与光缆接头盒以及光纤分纤箱连接。其中，预制缆一端设置有光缆接头，该光缆接头与光缆之间可相对转动。光缆接头盒以及光纤分纤箱上设置有与预制缆对应的线缆安装头。在预制缆与光缆接头盒或光线分纤箱连接时，将光缆接头与线缆安装头对接，并旋转光缆接头，使得光缆接头与线缆安装头卡装在一起，实现预制缆与光缆接头盒或光纤分纤箱连接。在拆分时，将线缆接头反向转动一定角度，预制缆即可与光缆接头盒或光纤分纤箱脱离连接。
本申请实施例提供的线缆保护壳为保护预制缆的一个装置，下面结合具体的附图以及具体的实施例对其进行详细的说明。
如图1及图2所示，图1示出了线缆保护壳的整体结构示意图，图2示出了线缆保护壳的打开状态示意图。在图1及图2示出的线缆保护壳10的主体包括两个壳体，为了方便描述将其分别命名为第一壳体10a及第二壳体10b。其中第一壳体10a与第二壳体10b可以围成容纳线缆接头50以及线缆安装头20的腔体。
首先说明一下第一壳体10a的结构，如图2中所示，第一壳体10a为半圆柱体结构，该第一壳体10a内具有两个凹槽，分别为第一凹槽12a及第二凹槽13a。第一凹槽12a及第二凹槽13a沿第一壳体10a的长度方向排列并连通。一并参考图2、图5及图6，图6示出了线缆保护壳10的使用状态参考图，图6为图5中A处的局部放大图。其中的第一凹槽12a用于容纳线缆接头50，而第二凹槽13a用于容纳线缆安装头20。
一并参考图3，图3示出了线缆保护壳的另一侧的结构示意图。在图3所示的结构中可以看出，第一壳体10a包括第一壳体结构18a及第二壳体结构17a，且第一壳体结构18a与第二壳体结构17a固定连接，当然也可以采用一体结构，比如第一壳体结构18a及第二壳体结构17a通过注塑或者挤压成型工艺一体成型。继续参考图3，第一壳体结构18a和第二壳体结构17a均为半圆柱形的壳体结构，且第二壳体结构17a的横截面尺寸大于第一壳体结构18a的横截面尺寸，即第二壳体结构17a的外径大于第一壳体结构18a的外径，在第一壳体结构18a与第二壳体结构17a的连接处形成一个台阶结构(图中未标示)。一并参考图2及图3，上述的第一凹槽12a设置在第一壳体结构18a内，第一凹槽12a即为第一壳体结构18a的内腔；同样的，第二凹槽13a设置在第二壳体结构17a内，第二凹槽13a即为第二壳体结构17a的内腔。在具体设置第一凹槽12a及第二凹槽13a时，第一凹槽12a及第二凹槽13a也均为半圆柱形的凹槽，且第一凹槽12a的直径小于第二凹槽13a的直径。 在第一凹槽12a用于容纳线缆接头50，在具体设置第一凹槽12a的直径时，第一凹槽12a的直径大于线缆接头50的直径。同样的，在第二凹槽13容纳线缆安装头20时，第二凹槽13的直径也大于线缆安装头20的直径。
应当理解的是，在图2及图3中，第一壳体10a的第一壳体结构18a及第二壳体结构17a采用半圆柱体形结构仅仅为一个具体的示例，在本申请实施例提供的第一壳体结构18a及第二壳体结构17a也可以采用长方体形或者其他形状的结构，仅需保证在第一壳体结构18a及第二壳体结构17a可以设置上述的第一凹槽12a和第二凹槽13a即可。此外，图2及图3中所示的第一凹槽12a及第二凹槽13a也仅为一个具体的示例，在本申请实施例提供的第一凹槽12a和第二凹槽13a还可以其他形状的凹槽，如矩形、三角形等不同形状的凹槽，但是无论采用什么形状的凹槽，第一凹槽12a的横截面的最小尺寸应大于线缆接头50的半径，第二凹槽13a的横截面的最小尺寸应该大于线缆安装头20的半径，以使得在容纳线缆接头50及线缆安装头20时，线缆保护壳10可以相对线缆接头50转动。
继续参考图2及图3，第二壳体10b与第一壳体10a对称，第二壳体10b也为半圆柱体结构，第二壳体10b包含第一壳体结构18b及第二壳体结构17b，且第一壳体结构18b及第二壳体结构17b与上述第一壳体10a的第一壳体结构18a及第二壳体结构17a相同，具体的可以参考上述对第一壳体10a的第一壳体结构18a及第二壳体结构17a的具体描述。此外，第二壳体10b也具沿第二壳体10b长度方向排列的第一凹槽12b及第二凹槽13b；其中，第一凹槽12b与第二凹槽13b之间也连通。第二壳体10b的第一凹槽12b及第二凹槽13b的设置方式可以参考上述对第一壳体10a的第一凹槽12a及第二凹槽13a的具体描述。
继续参考图1及图2，第一壳体10a与第二壳体10b采用可拆卸的固定连接，在图1中示出的第一壳体10a与第二壳体10b固定连接后，第一凹槽12a及第一凹槽12b围成容纳线缆接头50的第一容纳腔，第二凹槽13a及第二凹槽13b围成容纳线缆安装头20的第二容纳腔。一并参考图2，第一壳体10a与第二壳体10b的一侧转动连接，另一侧可以通过卡扣14a与卡槽14b的配合可拆卸的固定连接。在具体实现时，第一壳体10a与第二壳体10b可以采用一体成型的方式制备，且第一壳体10a与第二壳体10b相邻的一侧采用柔性连接，即第一壳体10a与第二壳体10b之间通过可折弯的连接部60连接，在第一壳体10a与第二壳体10b连接时，通过连接部60的形变实现第一壳体10a与第二壳体10b对盒，另一侧通过卡扣14a与卡槽14b的配合实现连接。
继续参考图2及图3，图2及图3示出了第一壳体10a及第二壳体10b的具体连接方式。如图3中所示，第一壳体结构18a的两侧分别设置有裙边结构，如第一壳体结构18a两侧分别设置有第一裙边结构19a和第二裙边结构16a，第一壳体结构18b两侧分别设置有第一裙边结构19b和第二裙边结构16b，且第一裙边结构19a的宽度等于第一壳体结构18a与第二壳体结构17a的直径差值，使得第一裙边结构19a与第二壳体结构17a齐平，连接部60的一侧与第二壳体结构17a及第一裙边结构19a连接，另一侧与第二壳体结构17b及第一裙边结构19b连接。第二裙边结构16a的宽度大于第一壳体结构18a与第二壳体结构17a的直径差值，因此，第二裙边结构16a外凸在第二壳体结构17a外。同样的第二裙边结构16b也外凸在第二壳体结构17b外。
继续参考图2，在设置卡扣14a与卡槽14b结构时，卡扣14a可以设置在第二裙边结构16a的内侧，卡槽14b设置在第二裙边结构16b上，其中，卡扣14a的个数可以为两个， 且两个卡扣14a沿第二裙边结构16a的长度方向排列。继续参考图2，两个卡扣14a的卡钩相背，即两个卡扣14a的卡勾的折弯方向相反；在对应设置卡槽14b时，卡槽14b的个数也相应可以为两个，且两个卡槽14b的排列方向沿第二裙边结构16b的长度方向排列。在卡扣14a与卡槽14b连接时，由于卡扣14a的卡钩折弯方向相反，在第一壳体10a与第二壳体10b沿其长度方向上出现错位时，仍可保持可靠的连接，提高了线缆保护壳10的可靠性。当然除了图2的示例外，两个卡扣14a也可以采用两个卡扣14a的卡钩折弯方向相向，同样可以提高卡扣14a与卡槽14b配合的稳定性，保证线缆保护壳10在使用时的可靠性。当然卡扣14a的个数也可以设置三个及三个以上，相应的卡槽14b的个数也可以为三个或三个以上。
继续参考图2，第一壳体10a的第二裙边结构16a还设置有缺口15。而第一壳体10a的第二裙边结构16b未设置。一并参考图1，在第一壳体10a与第二壳体10b对盒时，卡扣14a与卡槽14b之间卡合，且缺口15与第二裙边结构16b之间围成一个凹槽，在需要打开第一壳体10a与第二壳体10b时，可以将工具***到该凹槽内撬开，如使用一字螺丝刀或者其他的工具***到凹槽中转动，从而将第一壳体10a与第二壳体10b分开。继续参考图2，在设置有凹槽时，两个卡扣14a可以相对缺口15对称设置。在使用工具撬开时，使得两个卡扣14a的受力比较均衡。
继续参考图1及图2，在设置有上述缺口15时，为了避免缺口15直接外露，导致非工作人员可以直接看到凹槽的形状，并采用工具***到凹槽中撬开第一壳体10a及第二壳体10b，使得预制缆不安全的问题。本申请实施例在设置的第二裙边结构16a上还可以设置有遮挡缺口15的挡板11，该挡板11可相对裙边结构转动。在具体实现时，挡板11采用与第二裙边结构16a一体成型，且挡板11与第二裙边结构16a采用柔性连接，从而可以使得挡板11可以相对缺口15转动。继续参考图2，在设置挡板11时，挡板11位于缺口15内，且与第二裙边结构16a的侧面具有设定距离。如图1中所示，挡板11位于缺口15内，且距离第二裙边结构16a的侧面具有一定的距离。在第一壳体10a与第二壳体10b盖合时，挡板11位于缺口内。在需要使用工具***时，工具可以直接***到外露的凹槽中，从而方便工具***到缺口15中，方便用户操作。
当然，上述图2仅仅示例出了方便打开线缆保护壳10的一个具体的实现方式，在本申请实施例中，也可以采用第二裙边结构16a及第二裙边结构16b均设置缺口，且两个缺口在第一壳体10a与第二壳体10b对盒时，形成与工具配合的凹槽。
一并参考图1及图4，图4示出了线缆保护壳10的使用状态，在图1中线缆保护壳10的两端开口，在第一壳体10a与第二壳体10b对盒时，第一凹槽12a与第一凹槽12b围成容纳线缆接头50的第一容纳腔，且第一容纳腔的横截面大于线缆接头50的横截面；第二凹槽13a与第二凹槽13b围成容纳线缆安装头20的第二容纳腔，且第二容纳腔的横截面积大于线缆安装头20的横截面积。一并参考图4，第一容纳腔及第二容纳腔贯穿整个线缆保护壳10。在使用时，线缆30的线缆接头50位于第一容纳腔中，线缆安装头20位于第二容纳腔中，且线缆保护壳10可以相对线缆接头50以及线缆安装头20相对转动。由上述描述可以看出，在线缆30拔下时，需要线缆接头50相对线缆安装头20转动，而在本申请实施例提供的线缆保护壳10套装在线缆接头50及线缆安装头20时，在其转动时，同时相对线缆接头50及线缆安装头20转动，从而避免线缆接头50相对线缆安装头20转动，可以保护线缆接头50与线缆安装头20的连接。
此外，在线缆保护壳10装配在线缆30上时，由于第一容纳腔及第二容纳腔的尺寸分别大于线缆接头50及线缆30的直径尺寸，这样在设置线缆保护壳10时需要进行轴向限位。如图2及图5所示，图5示出了连接绳40、线缆30及线缆保护壳10的配合示意图。在本申请实施例中，第一凹槽12a远离第二凹槽13a的一端设置有用于卡装在线缆30的限位凸起101；即第一壳体结构18a的端部设置有凸起结构以限位线缆保护壳10的轴向运动。同样的，第二壳体结构18b的端部也设置有限位凸起102。在第一壳体10a及第二壳体10b形成如图1所示的限位结构103。
为方便理解线缆保护壳10与线缆30的连接方式，首先说明一下线缆30的结构以及线缆30与光纤接头盒或光纤分纤箱的连接方式。在线缆30与光纤接头盒或光纤分纤箱配合时，以光纤接头盒为例。线缆30与光纤接头盒之间通过一个连接绳40连接，该连接绳40的两端分别具有一个套环，其中的一个套环41套装在线缆30与线缆接头50之间，另一个套环41用于套装在光缆接头盒上。在线缆30从光纤接头盒上拔下时(线缆接头50与线缆安装头20之间分开)，可以通过连接绳40与光纤接头盒连接，避免线缆30掉落，方便再次安装。在连接绳40与线缆30连接时，如图5及图6所示，其中，图5示出了连接绳40、线缆30及线缆保护壳10的配合示意图，图6示出了图5中A处的局部剖视图。本申请实施例提供的线缆30的端部转动的连接头与线缆30之间形成一个台阶结构，线缆接头50的横向截面的直径大于线缆30的横向截面的直径，连接绳40的套环41套装在线缆30与线缆接头50之间，并且通过线缆30与线缆接头50进行限位。从而限定套环41的轴向运动。一并参考图1、图2及图6，保护壳10的端部设置的限位结构103的两侧可以分别抵压在套环41及线缆接头50上，从而限定线缆保护壳10的轴向运动。在线缆保护壳10套装在线缆30上时，虽然第一容纳腔及第二容纳腔的尺寸大于线缆接头50及线缆安装头20，但是由于套环41的轴向运动，无法将线缆保护壳10从线缆接头50上拔出，只能相对线缆接头50及线缆安装头20转动，从而保护了线缆接头50与线缆安装头20的连接，避免线缆30被恶意破坏。同时，采用线缆30与线缆保护壳10一对一的方式进行保护，在每个线缆30需要单独进行拆卸时，仅需要将其对应的线缆保护壳10拆卸下来即可，不会影响到其他线缆30，方便了线缆30的维护。
在线缆30与光纤接头盒之间没有连接绳40时，线缆保护壳10的限位凸起101***到线缆30与线缆接头50之间的间隙中进行限位，同样可以限定线缆保护壳10的轴向运动。
当然图1及图2仅仅示出了一种具体的可拆卸连接的方式，在本申请实施例提供的线缆保护壳10中，第一壳体10a及第二壳体10b还可以采用两侧均采用卡扣14a与卡槽14b的配合方式连接。即在第一裙边结构19a及第一裙边结构19b之间、以及第二裙边结构16a及第二裙边结构16b均采用上述的卡扣14a与卡槽14b的结构来连接。
通过上述描述可以看出，针对在暴露环境中使用的光纤接头盒或光纤分线箱，本申请实施例通过采用单零件、一体式的线缆保护壳10，实现对单个线缆接头50的独立保护。线缆保护壳10的本质在于对单个输入/输出缆连接头提供独立的物理保护，使用场景不依赖于接头盒的尺寸以及连接头的排布等，具有较强的通用性。除此之外，采用单零件设计，保证结构简单和安装方便。
本申请实施例还提供了一种通信设备，该通信设备包括设备主体，以及至少一个线缆30；其中，设备主体上设置有与至少一个线缆30一一对应的线缆安装头20；每个线缆30 上设置有线缆接头50，每个线缆接头50与对应的线缆安装头20可拆卸的固定连接；还包括套装在每个线缆接头50及对应的线缆安装头20的上述的线缆保护壳10。其中上述的设备柱体可以为光纤接头盒或光纤分纤箱，或者其他的通信设备。在线缆30与设备主体连接时，每个线缆30上套装有连接绳40，连接绳40与设备主体固定连接。具体的可以参考上述描述。在本实施例中，通过限位凸起101限定线缆保护壳10的轴向运动方向，且在线缆保护壳10套装在线缆接头50及线缆安装头20上时，线缆保护壳10可相对线缆接头50转动。而在线缆30从线缆安装头20中取下时，需要将线缆接头50相对线缆安装头20转动，而设置的线缆保护壳10避免了直接拧动线缆接头50，因此在线缆保护壳10的保护下无法直接将线缆接头50从线缆安装头20中拧下来，提高了线缆30的安全性。
以上，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以权利要求的保护范围为准。
