[0024] A base 3 for sealing the cavity is also provided in the shell 1, and a plurality of support members 31 are integrally connected to the base 3, and the support members 31 are in conflict with the bottom of the PCB main board 2. A plurality of sockets 32 for inserting the male end corresponding to the wiring assembly are provided on the base 3, and the support members 31 correspond to the puncture needles 4 one by one, and there is a spacing between adjacent support members 31. The base 3 and the PCB main board 2 are separated by the support members 31, and there is a spacing between adjacent support members 31, which also ensures the space between the base 3 and the PCB main board 2, and is convenient for the installation of the wiring assembly; the wiring assembly includes the puncture needle 4 and the spring 41, and the puncture needle 4 has a good conductive effect. The puncture needle 4 is provided with an extension portion at one end close to the PCB main board 2, and a support groove 311 for inserting the extension 42 portion is provided on the end surface of the support member 31 close to the PCB main board 2, thereby ensuring the use efficiency of the puncture needle 4 As a result, a pin 421 is fixedly connected to the top of the extension part of the puncture needle 4, and the pin 421 is inserted into the PCB main board 2 and welded to the PCB main board 2. A surrounding part 43 extending in the opposite direction to the extension part is provided on one side of the puncture needle 4, and a wiring channel is formed between the surrounding part 43 and the puncture needle 4. The support groove 311 on the support member 31 can support and position the puncture needle 4, so that the wiring channel can be connected to the wiring hole 21; the cross-section of the spring piece 41 is V-shaped, and one side of the spring piece 41 is fixedly connected to the puncture needle 4 by welding and is located in the wiring channel. The spring piece 41 is made of elastic metal material and has elastic deformation potential energy to fit the inner wall of the wiring channel. When the core wire is inserted into the wiring channel, the elasticity of the spring piece 41 is used to squeeze the core wire into the wiring channel to prevent the core wire from escaping from the wiring channel, thereby completing the fixation of the core wire.

[0025] The base 3 is provided with a plurality of pressing pieces 33, which correspond to the supporting pieces 31 one by one and are located between adjacent supporting pieces 31. The pressing pieces 33 and the base 3 are integrally formed and are made of rubber. The pressing pieces 33 are arranged at the sockets 32, and the pressing pieces 33 are in the shape of thin columns, so that the deformation of the pressing pieces 33 is more convenient. The end of the spring piece 41 away from the PCB main board 2 extends out of the wiring channel and contacts the pressing piece 33; the pressing piece 33 is pressed by the pressing piece 33 to deform the pressing piece 33, thereby driving the spring piece 41 to deform, so that the spring piece 41 is away from the inner wall of the wiring channel, so that the wiring channel is opened, and the core wire can be more conveniently inserted into the wiring channel; a screw thread is provided between the plurality of supporting pieces 31 on the base 3. The bolt passes through the sleeve 34, and a positioning portion 341 is provided on the top of the sleeve 34. A positioning hole 22 is provided on the PCB main board 2 for the positioning portion 341 to pass through. A protrusion 11 extending toward the top of the PCB main board 2 is fixedly connected to the inner top wall of the shell 1. The protrusion 11 contacts the top of the PCB main board 2, and a recess is formed on the outer side of the shell 1, so that the PCB main board 2 can be squeezed so that the PCB main board 2 is stably set on the top of the support member 31. A bolt insertion hole 12 connected to the sleeve 34 is provided on the shell 1, i.e., at the recess. The bolt is inserted into the sleeve 34 along the bolt insertion hole 12 and passes through the base 3, and can be threadedly connected with the male end while fixing the base 3, the PCB main board 2 and the shell 1 together.

[0026] A fixing part 5 is fixedly connected to one side of the shell 1, and an insertion hole is provided on the fixing part 5 for inserting the wiring harness. A ring array is provided on the side of the fixing part 5 away from the shell 1, and an extrusion hole is formed between the several extrusion parts 51. The aperture of the extrusion hole is larger than the aperture of the insertion hole. A locking nut 6 is threadedly connected to the outer peripheral wall of the fixing part 5, and a sealing ring 61 is sleeved on the wiring harness. The inner diameter of the sealing ring 61 is equal to the inner diameter of the insertion hole, and the outer diameter of the sealing ring 61 is larger than the aperture of the extrusion hole. When the wiring harness is inserted into the shell 1 along the insertion hole, the locking nut 6 is tightened to apply external force to the extrusion part 51, thereby squeezing the sealing ring 61, and making the wiring harness subject to external force and stably fixed in the corresponding position.

[0027] A sealing gasket 7 is attached to the bottom of the base 3 and the shell 1. The sealing gasket 7 is made of rubber material and has a through hole. The bottom surfaces of the shell 1 and the base 3 are both provided with a waterproof protrusion 8 in a ring shape, and the waterproof protrusion 8 is in contact with the sealing gasket 7. When the overall plug is installed on the male end by bolts, the waterproof protrusion 8 is embedded in the sealing gasket 7 by extrusion force, thereby ensuring the waterproof effect of the overall structure.

[0028] Working principle: the puncture needle 4 and the spring piece 41 are welded into an integral wiring assembly and fixed on the PCB main board 2. After the installation of the base 3 is completed, the wiring assembly is set between the PCB main board 2 and the base 3; when installing the core wire, after the core wire is inserted into the wiring channel, the elasticity of the spring piece 41 is used to squeeze the core wire into the wiring channel to prevent the core wire from escaping from the wiring channel, and the core wire is fixed. The installation of the core wire is more convenient by plugging in; when the core wire needs to be removed, the shell 1 is separated from the main body, and the pressing piece 33 is moved to deform the pressing piece 33, thereby driving the spring piece 41 to deform, so that the spring piece 41 is away from the inner wall of the wiring channel, so that the wiring channel is open, and the core wire can be more conveniently inserted into the wiring channel. The operation is convenient and quick, and the work efficiency is improved.
