AI Technical Summary
In practical applications, the static wrapping method of traditional waterproof sealing tape has several drawbacks. Firstly, it is prone to detachment or cracking due to insufficient elasticity caused by minor movements such as wire dragging, equipment vibration, or changes in ambient temperature. This creates channels for moisture penetration, leading to leakage or poor contact. Secondly, existing sealing structures have a narrow range of compatibility with wire diameters, especially for multi-strand cables or thicker wires with significant diameter differences. The sealing element often fails to deform flexibly with the outer diameter of the wire, resulting in seal failure.
It adopts a double-layer sealing design, combining a protective shell and a pressure cap. It uses high elasticity silicone to achieve dynamic sealing. The first and second sealing silicone parts cooperate with the wire half-groove to form a double waterproof barrier, which can adapt to the sealing requirements of wire micro-movement and different diameters. The screw is used to adjust the clamping force to ensure the sealing performance. The design of stepped groove, arc surface and positioning ribs can achieve precise positioning and fixation of silicone parts.
It achieves a tight seal for wire joints, preventing moisture penetration, improving waterproof performance and service life, adapting to changes in wire diameter, enhancing the sealing stability and reliability of the device in complex environments, and solving the problems of easy detachment of traditional tapes and poor compatibility with existing structures.
