AI Technical Summary

Technical Problem

Existing line clamps cannot meet high waterproof requirements, especially in humid or dusty environments where they cannot function properly. Furthermore, existing waterproof designs suffer from high costs, inconvenient operation, or low efficiency.

Method used

The cable clamp features a triple waterproof structure design, including a busbar sheath, a sealing ring, and reinforcing ribs. The sealing ring and the top cover are interference-fitted together, and the reinforcing ribs of the rectangular frame structure form a multi-layer waterproof structure, enhancing the waterproof performance of the cable clamp.

Benefits of technology

It enables the cable clip to operate normally for four hours in a five-meter-deep underwater environment, maintaining its existing appearance and production efficiency, reducing production costs, and improving the waterproof rating to IP28.

Abstract

The utility model relates to the technical field of blasting detonators, and discloses a triple waterproof wire clamp which comprises an upper cover and a lower shell, a reed for clamping a bus and a leg wire is arranged in the lower shell, a first reinforcing rib which is closed in the circumferential direction is arranged in the upper cover in a protruding mode, and a sealing ring is arranged on the lower shell around the reed. When the upper cover covers the lower shell, the first reinforcing rib is in interference fit with the sealing ring; the sealing ring is also provided with a bus sheath into which a bus can be clamped and a leg wire sheath into which a leg wire can be clamped, and the inner side of the sealing ring is also convexly provided with a second reinforcing rib. Through the triple waterproof structure design of the bus sheath, the sealing ring and the raised rectangular second reinforcing rib, the wire clamp can be completely immersed in an underwater environment with a depth of 5 meters to work normally for four hours.
