Bolt-free PCB wiring terminal provided with button

Abstract

The invention discloses a bolt-free PCB wiring terminal provided with a button. The bolt-free PCB wiring terminal provided with the button includes a base, a flat sheet spring, a clamping part, and a button; wherein the flat sheet spring and the clamping part are adaptively arranged in an accommodating cavity of the base, and the upper part of the flat sheet spring is elastically pressed against the top of the clamping part in an inclined manner; a button groove is arranged in the top of the base, and the button is slidably limited in the button groove; a first through hole for allowing the button to pass through, is arranged in the top of the clamping part, the side part of the base is provided with a wire inserting hole leading to the accommodating cavity and corresponding to the inclined upper part of the flat sheet spring, and the wire inserting hole allows a wire to push away the flat sheet spring and to be clamped between the flat sheet spring and the clamping part. According to the bolt-free PCB wiring terminal provided with the button, through improving a structure, the wiring capacity of the wiring terminal is improved and the reverse warping during wire withdrawing of a clamping spring can be avoided, and the damage to the wire due to wire withdrawing can be reduced; the bolt-free PCB wiring terminal provided with the button has the characteristics of wire fast connection, high reliability, and large wiring capacity.

Description

technical field [0001] The invention relates to a connection terminal, in particular to a screw-free PCB connection terminal with buttons. Background technique [0002] Terminal block is one of the commonly used components in electrical equipment, and its function is to connect wires. At present, with the improvement of industrial automation level, terminal blocks are widely used in industrial equipment, lighting, smart home and other industries due to their convenient wiring and easy disassembly and assembly, and their consumption has been rising year after year. [0003] With the continuous advancement of science and technology, people have higher and higher requirements for the connection method and wiring capacity of wires. While requiring safe, reliable and fast connections, they also put forward requirements such as small footprint and simple structure. The traditional terminal block is usually a bolt type terminal structure, as disclosed in the patent document US4171...

AI Technical Summary

Problems solved by technology

The traditional terminal block is usually a bolt type terminal structure, as disclosed in the patent document US4171152, by rotating the bolt, the crimping plate is lifted, and the external wire is inserted. After tightening, the crimping plate presses the wire, and the external wire It is also fixedly connected; this screw terminal structure has the disadvantage of inconvenient wiring

A plug-in type screw-free button terminal in the prior art eliminates the screw and replaces it with the cooperation of the button and the clip spring to fix the wire. This common plug-in type screw-free button terminal is due to Due to structural limitations, only wires with a small cross-sectional area can be connected, and when the clip spring is pressed through the button, the other side of the clip spring will be lifted, resulting in disadvantages such as wire withdrawal jamming and scratching the wire
