[0036] See also Figure 1-Figure 11 , an insulated piercing wire clamp with expandable functions, comprising a bolt assembly, a first housing 210, and a second housing 220, wherein the bolt assembly comprises a first bolt head 110, a retaining ring 101, and a screw rod 100;

[0037] The first housing 210 is provided with a first mounting groove 212 and a first external through hole 211. There is at least one first external through hole which is connected to the first mounting groove 212 through a second external through hole 213.

[0038] The first mounting groove 212 is assembled and fixed with the first mounting block 315 on the first sealing member 310, and a third external through hole 312 is provided at a position corresponding to the first mounting block 315 and the second external through hole 213;

[0039] The first sealing member 310 is further provided with a first fixing groove 311, and a first conductive sheet 410 is fixed in the first fixing groove 311;

[0040] The first conductive sheet 410 is provided with a first clamping end 411, a second clamping end 412, and a fourth external through hole 413;

[0041] The access end 503 of the functional device 500 passes through the first external through hole 211, the second external through hole 213, the third external through hole 312 and the fourth external through hole in sequence, so that the first conductive sheet is connected to the functional part 502 through the access end 503 for electrical conduction, and the functional part 502 is fixed in the functional housing 501;

[0042] The first clamping end 411 and the second clamping end 412 cooperate with the first auxiliary clamping end 421 and the second auxiliary clamping end 422 to clamp two cables to be connected, and they are both provided with puncture ends. When in use, the puncture ends pierce the insulating layer 610 of the cable 600 so that the puncture ends and the conductive core 620 are clamped to obtain electricity;

[0043] The first auxiliary clamping end 421 and the second auxiliary clamping end 422 are arranged on the second conductive sheet 420;

[0044] The second conductive sheet 420 is fixed in the second fixing groove 322 of the second sealing member 320. The second sealing member 320 is further provided with a second mounting block 321. The second mounting block 321 is assembled and fixed with the second mounting groove 221. The second mounting groove 221 is provided on the second housing 220. A fixing cylinder 130 is provided at the bottom of the second housing 220.

[0045] The screw 100 passes through the first shell 210, the first seal 310, the second seal 320, and the second shell 220 from top to bottom, and then enters the fixing tube 130 and is assembled with the nut 120 through threaded engagement to assemble and fix the first shell 210, the first seal 310, the second seal 320, and the second shell 220.

[0046] When in use, one end of the access terminal 503 can be connected to the first conductive sheet for conduction, and then the other end of the access terminal can be connected to a corresponding detection device for detection, such as a voltage detection circuit, a temperature sensor, etc., so as to obtain the current, voltage, temperature, etc. of the cable connected to the insulation piercing clamp, providing a hardware basis for subsequent real-time detection and automatic control.

[0047] Furthermore, the diameter of the second external through hole 213 is smaller than the diameter of the first external through hole 211. This design will form a boss at the connection between the first external through hole and the second external through hole.

[0048] The access end 503 is provided with a sealing ring 510, which is used to seal between the end face of the functional housing 501 and the boss to prevent foreign matter from entering the insulation piercing wire clamp. When in use, the sealing ring is pressed against the boss through the end face of the functional housing 501 to obtain a seal.

[0049] Furthermore, the second seal 320 is provided with a guide cylinder 330, the guide cylinder 330 has a hollow guide inner cylinder 331 inside, and the screw passes through the guide inner cylinder and enters the fixed cylinder 130. This design enables the first seal and the second seal to be pressed against each other through the guide cylinder, which can prevent the first seal and the second seal from being too close to each other, affecting the clamping performance of internal components and cables; on the other hand, it can make the fixing performance between the first seal and the second seal better.

[0050] Furthermore, the first sealing member 310 and the first clamping end 411 and the second clamping end 412 are respectively provided with a first compression area 313 and a second compression area 314 at their corresponding positions;

[0051] The second sealing member is provided with a first auxiliary compression area 323 and a second auxiliary compression area 324 at positions corresponding to the first compression area 313 and the second compression area 314;

[0052] When in use, the first compression area 313 cooperates with the first auxiliary compression area 323, and the second compression area 314 cooperates with the second auxiliary compression area 324 to compress the outer surface of the cable to fix the cable.

[0053] Furthermore, the first sealing member, the second sealing member, the first housing, the second housing, and the bolt assembly are all made of insulating materials, and the first conductive sheet and the second conductive sheet are made of conductive materials.

[0054] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work.
