A screw-free pcb terminal with a button

Abstract

The invention discloses a screw-free PCB terminal with a button, which comprises a base, a flat spring, a clamping part and a button; the base is provided with an accommodation cavity; the flat spring and the clamping part are fitted on In the accommodation cavity of the base, the upper part of the flat spring elastically resists the top of the clamping part in an oblique manner; a button groove is provided on the top of the base, and the button is slidably limited and installed in the button groove; The top of the component is provided with a first through hole that allows the button to pass through, and the side of the base is provided with a wire insertion hole leading to the accommodating chamber and corresponding to the oblique upper part of the flat spring, so that the wire When inserted, the flat spring can be pushed away and sandwiched between the flat spring and the top of the clamping part. The invention not only increases the connection capacity of the connection terminal through structural improvement, but also solves the phenomenon of warping when the clip spring withdraws the wire, can reduce the damage to the wire when the wire is withdrawn, and has the advantages of quick connection of the wire, high reliability, and high connection capacity specialty.

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
