How To Prevent Degradation Of Metal Waterproof Cable Joints?

The metal waterproof cable joint waterproof connector includes a screw sleeve with an inner hole. The outer circumference of the screw sleeve has a first external thread and a second external thread. The first external thread is threaded with a fastening nut, and the inner hole is equipped with a waterproof sealing ring. There is an inner shoulder blade in the middle of the hole, and the inner end of the waterproof sealing ring abuts on the inner shoulder blade. It is characterized in that a compression bushing is also provided in the inner hole, and the inner end of the compression bushing is inserted into the outer circumference and the inner hole of the waterproof sealing ring Between the wall of the hole, the outer annular end face of the compression bushing is provided with a plurality of arc grooves, and the inner end face of the annular shoulder at the outer end of the fastening nut has a plurality of inwardly protruding convex points. In the tightened state, the outer annular end surface of the compression bushing is in close contact with the inner end surface of the annular shoulder of the fastening nut, and the convex points are located in the arc groove. The waterproof sealing ring gives the compression bushing a counter-effect force, so that the arc groove in the compression bushing locks the convex points on the fastening nut, preventing the screw thread of the fastening nut from loosening due to the arrangement of oscillation, and it stops The effect of retreat.

The waterproof joint includes a waterproof bolt and a waterproof nut. The waterproof bolt includes a hollow external threaded coupling, a boss arranged in the center of the external threaded coupling, a clamping claw arranged at one end of the external threaded coupling, and the distance between the lower end of the boss A plurality of top limit stop blocks are provided, and a plurality of claws are provided at the end of the clamping claw away from the boss. A space is formed between two adjacent claws. The waterproof nut includes a hollow and is provided with an internal thread. The main body and the cap-shaped head extending downward from the lower end of the main body, a plurality of second limiting blocks are arranged at a distance from the end surface of the main body, a plurality of stop sliding blocks are arranged at a distance from the inner wall of the cap-shaped head, and a waterproof nut is screwed into an external threaded connection The upper end surface of the waterproof nut body is in contact with the lower end surface of the waterproof bolt boss. Each top limit block is located between two adjacent second limit blocks, and each stop slider is clamped into two clamping jaws. In the space between the adjacent claws, in this way, the waterproof nut can be prevented from slipping and pulling back.
