具体使用：Specific use:
两根待连接的网线，先将两根网线的前端网线绝缘外皮6剥掉，露出网线内的导线5，剥掉的绝缘外皮6的长度比连接主体1的一半略长点，最佳的长度是，裸露在外的单根导线5进入连接主体的导线槽11后，导线5的顶端位于连接主体1的中间，导线5的根部位于连接主体1的端点。然后依次将外盖42、垫片44、中心圆环3套入网线。将金属连接片2放入连接主体1的凹槽内12(一般情况下，金属连接片2已经安放在连接主体1的凹槽12内)，金属连接片2的齿牙朝外。将两根网线内的八根导线分开，导线5的根部抵在连接主体1的两端，将导线5引入导线槽11的入口。将中心圆环3从网线上向连接主体1的中部移动，此时，导线5在中心圆环3的作用下导入导线槽11内，两个中心圆环3移动至连接主体1的中间。将两个内盖41安装到连接主体1的两侧，内盖41内壁的压线凸条43将导线5压入导线槽11。将垫片44和外盖42移动至内盖41处，外盖42旋入内盖41时，内盖41的两个半盖向内产生压力，压线凸条43将导线5向内压入，金属连接片2的齿牙在压力的作用下刺破导线5的外皮与导线5电性连接，金属连接片2两侧的导线5通过金属连接片2完成电性连接。外盖42移动至中心圆环3，操作完成。For two network cables to be connected, first peel off the insulation sheath 6 at the front end of the two network cables to expose the wire 5 in the network cables. The length of the peeled insulation sheath 6 is slightly longer than half of the connecting body 1. The best length is that after the exposed single wire 5 enters the wire groove 11 of the connecting body, the top of the wire 5 is located in the middle of the connecting body 1, and the root of the wire 5 is located at the end of the connecting body 1. Then, the outer cover 42, the gasket 44, and the center ring 3 are sequentially inserted into the network cable. Put the metal connecting piece 2 into the groove 12 of the connecting body 1 (generally, the metal connecting piece 2 has been placed in the groove 12 of the connecting body 1), and the teeth of the metal connecting piece 2 face outward. Separate the eight wires in the two network cables, and place the roots of the wires 5 against the two ends of the connecting body 1, and introduce the wires 5 into the entrance of the wire groove 11. Move the center ring 3 from the network cable to the middle of the connecting body 1. At this time, the wire 5 is introduced into the wire groove 11 under the action of the center ring 3, and the two center rings 3 move to the middle of the connecting body 1. Install the two inner covers 41 to the two sides of the connection body 1, and the wire pressing convex strips 43 on the inner wall of the inner cover 41 press the wire 5 into the wire groove 11. Move the gasket 44 and the outer cover 42 to the inner cover 41. When the outer cover 42 is screwed into the inner cover 41, the two half covers of the inner cover 41 generate pressure inward, and the wire pressing convex strips 43 press the wire 5 inward. Under the action of pressure, the teeth of the metal connecting piece 2 pierce the outer skin of the wire 5 and electrically connect with the wire 5. The wires 5 on both sides of the metal connecting piece 2 are electrically connected through the metal connecting piece 2. Move the outer cover 42 to the center ring 3, and the operation is completed.
