Description

接头及包括该接头的电子产品  Connector and electronic product including the connector 技术领域Technical field
本发明属于接头结构技术领域，尤其涉及一种接头及包括该接头的电子产品。 The invention belongs to the technical field of joint structures, and in particular to a joint and an electronic product including the joint.
背景技术Background technique
目前的连接器的接头，例如USB（Universal Serial Bus，通用串行总线）连接器的接头，其接口本体大多直接通过SMT （Surface Mounted Technology，表面贴装技术）固定焊接到PCB上，尾部四个功能引脚表贴到PCB，另外两个接地插脚通过穿孔回流焊接到PCB，以增加USB和PCB的结合强度，但是现有技术中这种结构的接口本体不可转动，用户不能够根据所需的角度调整接口本体翻转的角度，用户对产品的体验受到限制，并导致用户使用不方便。Current connector connector, such as USB (Universal Serial Bus, universal serial bus) connector, the interface body is mostly directly through SMT (Surface Mounted Technology, surface mount technology) fixed soldering to the PCB, the four functional pins on the tail are attached to the PCB, and the other two ground pins are soldered back to the PCB through the vias to increase the bonding strength between the USB and the PCB, but in the prior art The interface body of this structure is not rotatable, and the user cannot adjust the angle at which the interface body is flipped according to the required angle. The user's experience on the product is limited, and the user is inconvenient to use.
现有技术中也有可旋转USB接头，其功能引脚由线缆或FPC（Flexible Printed Circuit，柔性印刷电路板）引出，然后焊接到电路板上，一般称其为线缆式旋转USB头或FPC式旋转USB头。由于USB接口本体在旋转时，固定连接于功能引脚上的线缆或FPC也相应的扭转，若扭转的角度过大，线缆、FPC将破损或断裂而导致接口失效，因此，现有技术中的这种USB接口本体不能实现任意角度旋转，只能在270°范围内旋转，用户体验受限，不便于用户的使用。There is also a rotatable USB connector in the prior art, and its function pin is made of cable or FPC (Flexible Printed Circuit, flexible printed circuit board) is taken out and soldered to the circuit board. It is generally called a cable-type rotating USB head or an FPC-type rotating USB head. When the USB interface body is rotating, the cable or FPC fixedly connected to the function pin is also twisted accordingly. If the angle of the twist is too large, the cable and the FPC will be broken or broken, resulting in interface failure. Therefore, the prior art The USB interface body in this kind cannot be rotated at any angle, and can only be rotated within a range of 270°, and the user experience is limited, which is inconvenient for the user.
另外，现有技术中的线缆式旋转USB头和FPC式旋转USB头，在使用过程中，USB接口本体经过多次旋转后，线缆或FPC易出现断裂或分层失效现象，同时线缆或FPC的屏蔽效果不佳，容易受外界干扰，产品可靠性差。而且线缆和FPC均需要通过手工焊接到电路板上，焊接操作难度大、焊接良率低，容易出现虚焊或者焊接短路的不良现象，焊接耗费工时较长，人力成本高；USB接口本体旋转多次后，线缆和FPC均有疲劳断裂的风险，产品可靠性差。特别是FPC式旋转USB头，其内部连接采用Hot bar（热压焊接）工艺，良率较低。In addition, in the prior art, the cable-type rotating USB head and the FPC-type rotating USB head, in the process of using, after the USB interface body is rotated a plurality of times, the cable or the FPC is prone to breakage or delamination failure, and the cable Or FPC's shielding effect is not good, it is easy to be interfered by the outside world, and the product reliability is poor. Moreover, both the cable and the FPC need to be manually soldered to the circuit board. The welding operation is difficult, the welding yield is low, and the phenomenon of soldering or soldering short circuit is prone to occur. The welding takes a long time and the labor cost is high; the USB interface body rotates. After many times, both cable and FPC have the risk of fatigue fracture and poor product reliability. Especially the FPC-style rotating USB head, the internal connection uses Hot Bar (hot press welding) process, low yield.
