The first locking block 3 and the second locking block 4 are both provided with a locking block locking groove 15 corresponding to the locking portion 6 of the docking piece, and the inner wall of the locking block locking groove 15 is provided with a locking block reinforcing convex edge 16 for locking the reinforced locking groove 10. The first locking block 3, the middle connection ear through hole 13 and the second locking block 4 are connected in sequence by screws, and the docking flange portion 5 enables the joint to adapt to more scenarios and has better adaptability; the extrusion of the locking block reinforcing convex edge 16 on the reinforced locking groove 10 can make the locking tooth 9 clamp more firmly and stably, with greater clamping force and better sealing.
[0020] The back sides of both ends of the first locking block 3 and the second locking block 4 are provided with locking block anti-retreat grooves 18, and the ends of the locking block anti-retreat grooves 18 are provided with locking block limiting protrusions 19. The front side of the locking seat 2 is provided with locking seat anti-retreat teeth 20 near the locking seat middle ear 12 to prevent the locking block limiting protrusion 19 from retreating after locking. When the first locking block 3 and the second locking block 4 clamp the connector 1 toward the middle, the locking seat anti-retreat teeth 20 can effectively prevent retreat, so that the clamping effect on the connector 1 is continuously maintained, effectively improving the cable clamping force and clamping stability, and preventing the cable from loosening after clamping.
[0021] The joint butt piece 1 is made of rubber material and plays a sealing and clamping role.
