The main body assembly 3 comprises a main body 35, a metal cover 31 and a sealing ring 34 which are coaxially arranged in the main body 35; wherein the central hole of the body 35 is divided into a first section 351 and a second section 352 in the axial direction, the first section 351 having a larger diameter than the second section 352, while a supporting inner step 354 is formed between the first section 351 and the second section 352. The seal ring 34 fits within the first segment 351, with the second end of the seal ring 34 supported on the support inner step 354; a clamping groove 353 is formed in the inner wall of the first section 351, a clamping outer step 313 is formed in the outer side wall of the metal cover 31, the metal cover 31 is positioned in the first section 351 of the main body 35 through the clamping of the clamping outer step 313 and the clamping groove 353, and meanwhile the sealing ring 34 is pressed on the supporting inner step 354. The snap-fit inner step 312 is located on the inner wall of the first end of the metal cap 31, and the metal structure can further improve the drawing strength. In this embodiment, the material of the metal cover 31 is any one of copper, aluminum, zinc alloy, and the like.

The annular positioning groove 2 is formed by the first end of the main body 35 and the edge portion 112 of the flange plate 11, and the first end of the metal cover 31 extends to the outside of the main body 35. Specifically, the edge portion 112 of the flange plate 11 is bent toward the second end side, and an annular positioning groove 2 is formed between the flange plate and the first end of the main body 35; the first end of the metal cap 31 extends to the outside of the main body 35, and can be inserted into the mounting hole of the case from the outside when assembled, thereby improving sealing performance. And the bending at flange board 11 border sets up, can make the middle part of flange board 11 form concave structure 111, is convenient for hold after the first end of metal cover 31 passes the box mounting hole to further promote sealing performance.

The main body assembly 3 further comprises a claw 32 coaxially fitted in the main body 35, the claw 32 comprises a ring body 321 fitted on the inner wall of the metal cover 31 and a clamping leg 322 formed on the inner wall of the ring body 321, and the inner end 3221 of the clamping leg 322 is inclined towards the outer end, namely the second end, of the main body assembly 3. Specifically, the plurality of clamping pins 322 are uniformly distributed on the inner wall of the central hole of the ring body 321 around the central circumference of the ring body 321, namely, the outer end of each clamping pin 322 is formed on the inner wall of the central hole of the ring body 321, and the inner end 3221 extends towards the center of the ring body 321 and inclines towards the outer end of the main body assembly 3, namely, the second end of the main body 35, so that the deformation during cable insertion and the elastic clamping of the cable are facilitated; in this embodiment, the claw 32 is made of stainless steel material to ensure its elasticity.
