Description

Technical Field

[0001] This utility model relates to the field of secondary cable insulation protection technology, specifically a convenient secondary cable head insulation clamp. Background Technology

[0002] Secondary cables are widely used in power systems, automation control, and other fields. Their ends (cable heads) need to be fixed with insulating adhesive and fitted with copper wire ends to achieve conductive connection and protection. Currently, existing methods for reinforcing the insulation of secondary cable heads have the following problems: The wires are prone to bending: The internal wires of the secondary cable are thin and numerous. When the copper wire ends are matched with the wires, if the ends of the wires are too long, it is difficult to directly fit the copper wire ends. Even with the help of external parts for fixation, the parts cannot move with the copper wire ends to fit the wires, causing the wires to bend during the installation of the copper wire ends, which affects the conductivity stability.

[0003] Large sealing gaps: The connection between the wire and the cable shell relies on insulating glue for sealing. However, the copper wire end is harder than the insulating glue. Directly applying it can easily create gaps at the connection, leading to an increased risk of leakage later and a significant reduction in moisture resistance.

[0004] Poor installation convenience: Existing reinforcement structures are mostly integrated designs, which cannot flexibly adapt to secondary cable heads of different specifications, and the installation steps are cumbersome, making it difficult to achieve rapid secondary insulation reinforcement (such as re-reinforcement during later maintenance).

[0005] To address the aforementioned issues, a secondary cable head insulation clamp needs to be designed that can move flexibly with the copper wire end, combines gathering, fixing, and sealing functions, and is easy to install, in order to improve the reliability of secondary cable head reinforcement and operational efficiency.

The characteristic feature is that the insulation clip includes: The main body of the insulating clamp is a movable ring 2, which is movably sleeved on the outside of the wire 101, and the outer surface of the movable ring 2 abuts against the inner side of the copper wire end 208. It is used to synchronously gather the wire 101 as the copper wire end 208 moves to prevent bending. The movable ring 2, the plug ring 205 and the plug ring 204 are made of integrated insulating plastic material.

[0022] Sealing assembly: includes a plug ring 205 and a sealing ring 206 fixedly connected to the outside of the movable ring 2. The plug ring 205 is movably plugged into the inside of the copper wire end 208 and sleeved on the outside of the wire 101. The sealing ring 206 is sleeved on the outside of the plug ring 205 and abuts against the end of the copper wire end 208.

[0023] Limiting assembly: includes a limiting plate 201 fixedly connected to the outside of the moving ring 2, and a connecting ring 202 fixedly connected to the end of the limiting plate 201, the connecting ring 202 being movably sleeved on the outside of the cable 1; The fixed sealing assembly includes a rubber ring 207 sleeved on the outside of the cable 1, and a fixing ring 203 sleeved on the outside of the rubber ring 207. A limiting plate 201 is movably inserted into the fixing ring 203. A plug ring 204 is fixedly connected to the side of the moving ring 2 near the rubber ring 207, and the plug ring 204 is movably inserted into the inside of the rubber ring 207. A sliding groove is formed on the inner side of the fixing ring 203, and the limiting plate 201 slides along the sliding groove. At least three sets of limiting plates 201 are provided, and they are evenly distributed along the circumference of the moving ring 2. An annular groove is formed on the side of the rubber ring 207 near the moving ring 2, and the plug ring 204 is adapted to the annular groove.

[0024] The installation and usage steps are as follows: Pre-assemble the fixing sealing assembly: Tightly fit the rubber ring 207 on the cable 1 near the end, and then fit the fixing ring 203 on the outside of the rubber ring 207, ensuring that the groove on the inside of the fixing ring 203 faces the direction of the wire 101.
