the method comprises the following steps: one end of a plug 11 is inserted into the mounting hole 16, a plurality of pins 21 are inserted into the jack 19, a pressing plate 18 is fixed at one end of the clamping shell 2 through bolts and fixing holes 17, the cover plate 5 is disassembled and opened, a circuit is connected into the circuit, one end of the circuit is fixedly connected with a wiring board, the other end of the circuit penetrates through the interior of the wire conveying pipe 4, the second screw rod 10 is screwed to move towards the other side of the interior of the inner cavity 15 until one end of the second screw rod 10 is connected with the circuit, redundant circuits are wound and arranged in the placing groove 14, the first screw rod 9 is screwed to move towards the other side of the interior of the inner cavity 15 until the elastic pad 20 enters the interior of the placing groove 14 to extrude the circuits, and the cover plate 5 is fixed at the top of the clamping shell 2;

step two: the top of the line is in contact with a push plate 30 in the wire conveying pipe 4, the bolt rod 6 is screwed to move downwards, the top plate 28 and the push plate 30 are driven to move downwards until the push plate 30 is tightly clamped and extruded with the line, and one end of the line is fixedly connected with an external communication cable;

step three: insert the inside of spacing groove 22 through plug 11 with joint shell 2 one end, contact pin 21 inserts the inside of jack 19, and connecting plate 3 one end rotates the inside that the joint got into locating hole 8 round pivot 33, and fixed shell 1 is inside to be connected with outside communication line through the circuit.

When the invention is used, one end of the plug 11 is inserted into the mounting hole 16, the plurality of pins 21 are inserted into the insertion holes 19, and the pressure plate 18 is fixed at one end of the clamping shell 2 through the bolts and the fixing holes 17. The cover plate 5 is detached and opened, the circuit is connected into the circuit, one end of the circuit is fixedly connected with the wiring board, and the other end of the circuit penetrates through the wire conveying pipe 4 outwards. The second screw rod 10 is screwed to move towards the other side inside the inner cavity 15 until the elastic pad 20 at one end of the second screw rod 10 is connected with the wire. The redundant wires are wound and arranged in the placing groove 14 in a neat and neat way, the first screw rod 9 is screwed to move towards the other side in the inner cavity 15 until the elastic cushion 20 enters the inner part of the placing groove 14 to press the wires. The cover plate 5 is fixed on the top of the clamping shell 2, and two ends of the cover plate are fixedly connected with the clamping shell 2 through screws and screw holes 12. The top of the line is in contact with the push plate 30 inside the wire conveying pipe 4, the bolt rod 6 is screwed to move downwards, the bolt rod 6 rotates around the bearing 32 to drive the top plate 28 and the push plate 30 to move downwards until the push plate 30 is tightly clamped to extrude the line, and one end of the line is fixedly connected with an external communication cable. When in use, the damping spring 31 plays a role in damping and buffering, the push plate 30 cannot generate large indentation on the upper part of the line, and the line can keep high communication efficiency. One end of the clamping shell 2 is inserted into the limiting groove 22 through the plug 11, and the pin 21 is inserted into the jack 19. The metal sleeve 26 inside the jack 19 is tightly contacted with the pin 21, so that the communication continuity can be maintained. One end of the connecting plate 3 rotates around the rotating shaft 33 to be clamped into the positioning hole 8, so that the position between the clamping shell 2 and the fixing shell 1 is limited, and the connecting plate is not easy to fall off in use. The inside of the fixed shell 1 is connected with an external communication line through a line, and the communication line is connected for normal use. External signals are transmitted to the inside of the card housing 2 through cables, transmitted to the inside of the stationary housing 1 through the plug 11, and transmitted to other instruments. The contact pin 21 can be replaced independently after being damaged, so that the whole fixed shell 1 or the clamping shell 2 is prevented from being replaced, and the maintenance cost in use is saved. The insert pin 21 can be quickly and fixedly connected by the bolt head 23 and the buckle 24 at one end of the insert pin 21. And plug 11 can be connected with joint shell 2 detachable through contact pin 21, can be solitary follow joint shell 2 one end dismantlement after 11 internal damages of plug and change. After the circuit is connected many times with outside communication cable, the junction shortens the back, unscrews first screw rod 9, can pull out the circuit that inside was stored, and the circuit increases and makes things convenient for follow-up and outside communication cable to be connected.
