AI Technical Summary

Technical Problem

Existing plug-in terminal blocks require tools for wiring, making operation inconvenient and the housing design complex and assembly difficult.

Method used

Design a terminal block comprising a housing body, conductive components, and spring contacts. The housing body is an integral structure. The conductive components and spring contacts are fixed by fixing grooves. The protective cover can be opened for wiring. A locking structure enables the cover to be detachably connected. The conductive components and spring contacts are fixed by limiting steps and support arms. Positioning posts and protrusion structures ensure stable installation.

Benefits of technology

It achieves screwless fixing, simple operation, convenient wiring, and the protective cover can prevent the wiring part from being exposed, thus improving safety and convenience.

Abstract

This utility model provides a direct-insertion terminal block, including a housing body, a conductive element, and a spring contact. The housing body has a fixing groove with an opening at the lower end. The conductive element and the spring contact are inserted into and fixed in the fixing groove through the lower opening. The upper end of the housing body has a insertion hole communicating with the fixing groove for inserting wires. The spring contact is located at the upper end of the conductive element and opposite to the insertion hole. The lower end of the conductive element extends to a connection portion for connecting wires. The lower end of the housing body has an openable protective cover plate with an outlet hole opposite to the connection portion for wires to extend out. With this structure, the conductive element and the spring contact can be inserted into and fixed in the fixing groove through the lower opening. The housing body is designed as a one-piece structure, requiring no screws for installation, making installation convenient. Wires can be connected to the connection portion by opening the protective cover plate, making operation convenient. Covering the protective cover plate prevents the connection portion from being exposed, effectively preventing electric shock.
