Description

Technical Field

[0001] This utility model relates to the field of cable grounding wire technology, and in particular to a waterproof structure for cable grounding wire. Background Technology

[0002] Currently, commonly used cable accessories in China mainly include cold-shrink, heat-shrink, and prefabricated detachable connectors. Due to practical engineering needs and the installation requirements of the cable accessories themselves, the cable's metal shield grounding wire needs to be led out and connected to the grounding system. The common method for manufacturing cable grounding wires is to lead out the cable's metal shield wire, then crimp it to the grounding terminal and use heat-shrink tubing for shrink protection. Currently, when the cable grounding wire is subjected to bending, compression, or mechanical damage, the protective heat-shrink tubing may develop defects and lose its original sealing performance, resulting in water ingress from the grounding wire into the cable, leading to cable malfunctions. Therefore, those skilled in the art provide a waterproof structure for cable grounding wires to solve the problems mentioned in the background art. Utility Model Content

[0017] Reference Figures 1-4 A waterproof structure for a cable grounding wire includes a connecting plate 1. A grounding wire 2 is fixedly installed on the surface of the connecting plate 1. A threaded groove is formed on the surface of the grounding wire 2, and a threaded ring 3 is threadedly connected to the surface of the threaded groove. A sealing ring 4 is provided inside the threaded ring 3. The size of the sealing ring 4 is adapted to the size of the grounding wire 2. The sealing ring 4 seals the connection between the grounding wire 2 and the support block 6. Using the sealing ring 4 and the threaded ring 3, when a person rotates the threaded ring 3 through the grounding wire 2, the threaded ring 3 will move, causing the sealing ring 4 to move. The sealing ring 4 will then seal the grounding wire 2. The sealing at the connection between wire 2 and support block 6 is achieved by a protective component 5 inside the grounding wire 1, a support block 6 sleeved on one side of the surface of the grounding wire 2, a positioning component 7 inside the support block 6, a sealing cover 8 fixedly installed on one side of the surface of the support block 6, a through groove on one side of the surface of the support block 6, a cable 9 inside the through groove, a buffer pad on the surface of the cable 9 to protect the internal core of the cable 9, and limiting blocks fixedly installed on both sides of the surface of the support block 6, with a gap between the bottom of the limiting block and the cable 9, thus protecting the cable 9.

The size of the insulating pad 54 is adapted to the size between the protective pad 53 and the insulating pad 51. The insulating pad 54 and the protective pad 53 protect the wires 52.

[0019] In particular, during use, the personnel install the insulating pad 51 inside the grounding wire 2, and then install the protective pad 53 on the surface of the wire 52. The insulating pad 54 between the protective pad 53 and the insulating pad 51 will protect the wire 52, and the insulating pad 51 can improve the insulation of the grounding wire 2. The setting of the insulating pad 54 and the protective pad 53 can protect the wire 52 and improve the service life of the grounding wire 2.

Then, the personnel rotate the threaded rod 72 through the mounting block 71. When the threaded rod 72 rotates, it will drive the arc plate 73 to move downward. When the arc plate 73 moves downward, it will clamp and position the grounding wire 2. The ball bearings 74 inside the groove can support the grounding wire 2, improving the efficiency of installing the grounding wire 2. Together with the sealing ring 4 and the threaded ring 3, the connection between the support block 6 and the grounding wire 2 is sealed.

[0022] Working principle: First, the insulating pad 51 is installed inside the grounding wire 2. Then, the protective pad 53 is installed on the surface of the wire 52. The insulating pad 54 between the protective pad 53 and the insulating pad 51 will protect the wire 52. The insulating pad 51 can improve the insulation of the grounding wire 2. The setting of the insulating pad 54 and the protective pad 53 can protect the wire 52. Then, when installing the grounding wire 2, the personnel insert the grounding wire 2 into the support block 6. Then, the personnel will rotate the threaded rod 72 through the mounting block 71. When the threaded rod 72 rotates, it will drive the arc plate 73 to move downward. When the arc plate 73 moves downward, it will clamp and position the grounding wire 2. The ball bearings 74 inside the groove can support the grounding wire 2, improving the efficiency of the installation of the grounding wire 2.
