[0002] Leakage-proof cable joints are support devices for quickly connecting two sets of cables. The sealing and mechanical protection of the joint are essential to ensure its safe and reliable operation. Moisture and humidity should be prevented from seeping into the cable joint, which could lead to leakage, short circuits, and other problems. With the continuous development of technology, people have increasingly higher requirements for the manufacturing process of leakage-proof cable joints.
[0003] Existing cable connectors have certain drawbacks in use. First, they may leak water or electricity, which cannot be detected in time and can easily cause short circuits, fires, and other problems. Existing cable connectors have certain adverse effects on actual use. Therefore, we propose a real-time detection leak-proof cable connector. Utility Model Content
