在盖体15上设置有凸台21,凸台21具有与导电片9的后端11相对应的坡面,并且所述盖体15在关闭时凸台21位于所述嵌入口20的前侧或后侧;如此将导电芯的外皮剥除后,将导电芯搭载在嵌入口20上,导电芯在嵌入口20的前部伸出,在盖体15扣合关闭时,该凸台21会压住导电芯并对导电芯进行拉拽,同时将导电芯压在导电片9的后端拱起的位置上实现电连接;又或者该凸台设置在盖体在关闭时与嵌入口对应的位置处,如此在盖体15扣合关闭时,该凸台可以将导电芯压在嵌入口20上。如果该嵌入口设置有锋利的边沿,也可以通过盖体直接带动光电复合缆的导电芯(未剥除外皮)进入嵌入口并电连接。The cover 15 is provided with a boss 21, the boss 21 has a slope corresponding to the rear end 11 of the conductive sheet 9, and when the cover 15 is closed, the boss 21 is located at the front side or the rear side of the insertion opening 20; after the skin of the conductive core is stripped off, the conductive core is mounted on the insertion opening 20, and the conductive core protrudes from the front of the insertion opening 20.

The above-mentioned process can also be realized when the cover body 15 is closed. Specifically, a boss 23 is set on the cover body 15, and the boss 23 is arranged relative to the both sides of the insertion port 22, so that only the conductive core of the photoelectric composite cable with the outer skin needs to be carried on the insertion port 22 during assembly, and then the cover body 15 is fastened and closed. The conductive core can be pressed into the insertion port 22 to realize electrical connection with respect to the bosses 23 on both sides of the insertion port 22; if the insertion port 22 is a bayonet similar to a Y shape, The boss can also be arranged at a position corresponding to the insertion opening to directly press the conductive core into the insertion opening 22 .

The space between the cover body 15 and the housing chamber 2 is an extrusion space, and at least a part of the piercing portion 24 is located in the extrusion space; when the lid body 15 is closed, the extrusion space gradually decreases, so that the cable body of the photoelectric composite cable placed on the piercing portion 24 is squeezed by gradually buckling the cover body 15 until the piercing portion 24 pierces into the cable body of the photoelectric composite cable, thereby realizing electrical connection. The rear end of the conductive sheet 9 is configured to have an extension part bent into the accommodation chamber 2, the extension part forms a U-shaped structure with the rear end of the conductive sheet, and the piercing part 24 is arranged on the extension part, that is, the piercing part 24 is arranged in parallel with the parts located on both sides of the accommodation chamber 2 and the piercing part 24 is located in the accommodation chamber 2 with the sharp direction upward.

When using it, only the optical fiber core wire needs to be stripped off instead of the conductive core. The conductive core is still in the main body of the photoelectric composite cable. The piercing part 24 is formed by the conductive sheet 9 , and its sharp thorns are enough to pierce the sheath of the photoelectric composite cable, while the piercing part 24 is fixed at a position corresponding to the conductive core.
盖体15可以在与刺入部24对应的位置上设置台阶25,刺入部24与台阶25尽量靠近尾部方便受力;将光电复合缆放置在容纳腔2内,此时光电复合缆位于刺入部24上并高出容纳腔2,该高出的部分即为需要进行挤压的挤压空间。在所述盖体15关闭过程中,通过盖体15对光电复合缆进行挤压,挤压空间逐渐减小,使刺入部24刺穿进入光电复合缆,如图8所示光电复合缆完全位于容纳腔2内,最终在盖体15关闭时使刺入部24与光电复合缆的导电芯电连接。The cover body 15 can be provided with a step 25 at a position corresponding to the piercing portion 24, and the piercing portion 24 and the step 25 are as close as possible to the tail to facilitate the force receiving; the photoelectric composite cable is placed in the housing cavity 2, and the photoelectric composite cable is located on the piercing portion 24 and is higher than the housing chamber 2, and the raised part is the extrusion space that needs to be squeezed. During the closing process of the cover body 15, the photoelectric composite cable is squeezed through the cover body 15, and the extrusion space is gradually reduced, so that the piercing part 24 penetrates into the photoelectric composite cable. As shown in FIG.
