Push-pull locking device of novel electric car connector

Abstract

The invention relates to a push-pull locking device of a novel electric car connector. A primary buckle assembly comprises a button and a button buckling element; and a secondary buckle assembly comprises a plug buckling element, a rotating shaft, a torsional spring, a plug buckling hole and a warped-end slide groove. In an unlocking state, the button buckling element slides to the rear end of the warped-end slide groove; a plug guide post does not completely slide into a slide sleeve guide groove; a slide sleeve component does not wrap a plug component; and the plug component is separated from a socket component. In a locking state, the button buckling element passes through the warped part at the front end of the warped-end slide groove, and slides into the plug buckling hole from the warped-end slide groove; the plug guide post completely slides into the slide sleeve guide groove; the slide sleeve component wraps the plug component; and the plug component is matched with the socket component for insertion. The push-pull locking device has the beneficial effects that push-pull once locking is realized; the push-pull locking device is simpler, more convenient and easier to use in comparison with a flip-type locking device or a handle locking device; and by the mode of a button unlocking device, unlocking can be realized only by pressing an unlocking button.

Description

technical field [0001] The invention relates to the field of locking devices for connectors, in particular to a novel push-pull locking device for connectors of electric vehicles. Background technique [0002] At present, with the huge demand for new energy vehicles in China, the development of electric vehicles in China has become the general trend. Electric vehicles and related industries such as charging equipment, power distribution equipment and other fields have a bright future in China. However, in the current situation, although the country has vigorously advocated it, and various enterprises are full of enthusiasm, a series of technical problems such as "difficult to charge", "high cost" and "safety" have become restrictions on the entry of electric vehicles into ordinary people. bottleneck at home. [0003] Among these technical issues, the "safety" of charging is one of the major issues. At present, one of the commonly used charging protection measures is to ins...

AI Technical Summary

Problems solved by technology

At present, one of the commonly used charging protection measures is to install protective components on the connector ports of electric vehicles. Most of them are openable cover-shaped components. The disadvantage of being easy to be loosened or opened by mistake

[0004] The step-by-step locking device developed on the basis of the open-type cover-shaped parts has better reliability and safety, but its disadvantages are that the structure is more complicated, the use is difficult, and the maintenance cost is higher.
