Description

TECHNICAL FIELD

These problems may lead to the decrease of the safety and stability of the equipment, and even increase the risk of fusing.

[0003] Firstly, the compression plate in some designs does not fully exert its compression effect, leading to insufficient pressure on the wire during wiring. This can cause poor contact and heat generation when current passes through, which can easily lead to overheating and even fusing. Some designs of the compression plate can only compress part of the wiring area, and cannot cover the entire contact surface of the wiring, which can cause local overheating, especially when working at high current, local temperature rise can cause fusing, causing equipment damage or safety hazards.

[0004] In the existing design, the protection cover usually needs to be installed on the wiring terminal using a manual clamping mechanism. Although the clamping mechanism can provide good sealing, in actual operation, due to the complex design of the clamping part or the smoothness of the clamping groove structure, the installation and disassembly process is often tedious and laborious, which not only increases the labor intensity of the operator, but also may cause damage to the protection cover or clamping structure during disassembly.

In the prior art, many wiring terminals need to be disassembled with tools or manually, which brings inconvenience to daily maintenance and repair. If the design lacks convenient disassembly function, it will affect the use efficiency of the equipment and increase the maintenance time. UTILITY MODEL CONTENTS
