Description

Technical Field

[0001] The utility model relates to the technical field of wiring terminals, in particular to a waterproof wiring terminal. Background Art

[0002] Terminal blocks are components used for electrical connections, typically connecting two or more wires. They are widely used in electrical and electronic equipment to ensure safe, stable, and reliable connections. The most important feature of terminal blocks is their waterproof performance, which protects the internal electrical connections from moisture and corrosion.

[0003] At present, there are still some deficiencies in the terminal blocks, such as poor waterproof performance of the terminal blocks:

[0004] In order to overcome the problem of insufficient waterproofness of the terminal block, a Chinese patent of the prior art (publication number: CN214505897U) discloses a waterproof and dustproof spring-type terminal block. The terminal block can be wrapped with a waterproof sleeve and a sealing ring at one end of the inner side of the waterproof sleeve, thereby achieving a good dustproof and waterproof effect, preventing water from entering the terminal block and causing circuit failure and safety accidents. The clamping mechanism drives the elastic clamping plate to move, so that the elastic clamping plate and the fixed clamping plate clamp and fix the wire end. The operation is simple, the fixing is good, and it is convenient to install and disassemble.

[0005] However, the wiring terminals currently in use still have certain deficiencies. Although the above-mentioned document uses a waterproof cover for sealing, relatively small connecting wires are still prone to water vapor penetrating into the terminal. Secondly, although the holes used for operation in the wiring terminals are small, they are also prone to water vapor penetration, which can easily affect the safe use of the connecting wires. There are certain deficiencies in use, so it is necessary to improve the existing structure. Utility Model Content
