[0024] Specifically, during the insertion of the male buckle 1, the fixing block 3 is compressed by the inner wall of the female buckle 13, which compresses the locking spring 11. When the male buckle 1 is in place, the locking spring 11 is reset and pushed out. The fixing block 3 and the fixing groove 14 on the inner surface of the female buckle 13 are engaged. At the same time, the rubber pad 9 is compressed to form a buffer sealing layer.
[0025] The bottom surface of the male buckle 1 is fixedly connected with a plug 23, which has an insulating protection design to prevent the risk of short circuit at the terminal.
[0026] The straight pipe module 19 has a female buckle 13 fixedly connected to the right side surface and a male buckle 1 fixedly connected to the left side surface.

[0027] The reducing module 20 has a female buckle 13 fixedly connected to the right side surface and a male buckle 1 fixedly connected to the left side surface. The asymmetrical design is suitable for multiple cable specifications.
[0028] The elbow module 21 has a male buckle 1 fixedly connected to its upper surface and a female buckle 13 fixedly connected to its right side surface. It has a built-in cable protection structure to control the safe bending radius.

The fixing plate 2 and the fixing groove 14 cooperate to form a rigid connection frame. When the fixing block 3 is squeezed by the inner wall of female buckle 13, it compresses the locking spring 11. After reaching the correct position, the spring returns to its original position and pushes the locking plate 10 out, forming a mechanical self-lock with the fixing groove 14, ensuring that the axial tensile strength between pipe sections is ≥500N. The rubber pad 9 deforms under pressure to form the first buffer sealing layer. After the clamp 6 is tightened by the bolt 8, its clamping force makes the sealing ring 5 form a second radial seal with the pipe surface. Combined with the conical surface design at the pipe connection, the IP68 protection level is achieved.
