The clamping rod 24 is made of non-conductive material, and the wire post 25 is made of conductive material and a wire is connected between the wire post 25 and the conductive block 26.

[0022] A limit shell 10 and an auxiliary block 11 are respectively arranged on the opposite side of the two insulation blocks 7 from top to bottom, a connecting head 12 is arranged between the limit shell 10 and the opposite side of the auxiliary block, one side of the connecting head 12 passes through the outer shell 1 and extends to the outside of the outer shell 1, a telescopic column 13 is fixedly connected to the top of the connecting head 12, a spring is arranged on the surface of the telescopic column 13, the top of the telescopic column 13 passes through the limit shell 10 and extends to the inside of the limit shell 10, the top of the telescopic column 13 is fixedly connected to the stretching column 14, the top of the stretching column 14 passes through the limit shell 10, the insulation block 7 and the outer shell 1 in sequence and extends to the outside of the outer shell 1.

[0027] The working principle of the high temperature and high pressure sealed connector provided by the present invention is as follows:

[0028] First, pull out the wire clamping device, and then place the copper wire part on the wire into the wire clamping device 2 from the right side. After the wire is placed, release the force of pulling out the wire clamping device 2. At this time, the tension spring 17 will pull the wire clamping device 2 into the shell 1. When the wire clamping device 2 is pushed forward, the wire clamping device 2 will clamp the copper wire. When the wire clamping device 2 enters the shell 1, the support block 22 will move to one side due to the elastic spring 23. When the support block 22 moves, the clamping rod 24 also moves with the support block 22. When the clamping rod 24 moves inside the slide groove, the wire posts 25 on the two clamping rods 24 will clamp the copper wire placed inside the wire clamping device 2. In this way, one end of the line will be fixed on the wire clamping device 2. When the wire clamping device 2 is reset, push the threaded ring 5 a little to the left, and then align the threaded ring 5 with The wire fixing block 3 contacts, and then the threaded ring 5 is rotated. Due to the rotation of the threaded ring 5, several wire fixing blocks 3 will be deformed due to the movement of the threaded ring 5. When the threaded ring 5 moves to one end of the wire fixing block 3, the wire fixing block 3 will be deformed. In this way, the wire fixing block 3 will clamp the surface of the wire. When the connector needs to be connected to the socket, the stretching column 14 is pressed. When the stretching column 14 moves downward, the telescopic column 13 will shrink. At this time, when the telescopic column 13 is extended and retracted, the groove block 16 will also move downward. In this way, the groove block 16 will be separated from the groove plate 15, and then the stretching column 14 is pushed to one side. When the stretching column 14 moves to one side, the connector 12 will be pushed out of the housing 1. After the connector is pushed out, the connector 12 can be connected to the socket. When the device needs to replace the wires, the steps of installing the wires can be reversed.

[0029] Compared with the related art, the high temperature and high pressure sealed connector provided by the present invention has the following beneficial effects:

[0030] The setting of the wire clamping device 2 can make it convenient to fix the wires by using the wire clamping device 2, and then it is convenient to take out the line, so that the line can be replaced better, which saves the cost of using the connector on the one hand, and increases the practicality of the connector itself on the other hand. The matching use of the wire fixing block 3 and the threaded ring 5 can make the wire fixing block 3 better fix the line, which increases the stability of the connector connecting the line and increases the safety during use. The design of the protruding block 4 can make the protruding part of the protruding block 4 better squeeze and fix the line, which increases the stability of the wire fixing block 3 when it is fixed, and the tensile column 14 and the concave The groove block 16 and the groove plate 15 are used in combination, so that the connector 12 can be retracted into the housing 1 when the connector is not connected. This can reduce the situation where the connector 12 is exposed to the outside and is damaged by external forces. This design also increases the safety of the connector 12 when in use and increases the practicality of the connector itself. The clamping rod 24 and the wire post 25 in the wire clamping device 2 are used in combination, so that the support block 22 can be directly used to move, so that the wire post 25 can be used to clamp the line, and then the conductive operation can be performed. The conductive block 26 is not provided in this way. First, the contact area of ​​the copper wire can be increased, and the electrical signal can be better transmitted.
