A step-by-step locking device for electric vehicle connector plug

Abstract

The invention relates to the field of locking devices of connectors, in particular to a step-by-step locking device for a plug of a novel electric car connector. The step-by-step locking device comprises a plug component, a socket component and a handle component, wherein a first guide post of the plug, a second guide post of the pug and a socket guide post respectively slide to the head ends of a first track, a second track and a third track in a locking state; the first guide post of the plug, the second guide post of the plug and the socket guide post respectively slide to the tail ends of the first track, the second track and the third track in an unlocking state; and when the locking state is converted into the unlocking state, particularly, the second guide post of the plug slides to the middle part from the head end of the second track, the second guide post of the plug is blocked at the upper end of an offset sub-rail, and the handle component exerts up-inclined external force, so that the second guide post of the plug moves to the lower end of the offset sub-rail, and further slides to the tail end. The step-by-step locking device has the beneficial effect that a user does not need to directly contact an outer cover of the connector when locking or unlocking the outer cover, so that the electric potential safety hazard when an electric car is charged is removed.

Description

technical field [0001] The invention relates to the field of locking devices for connectors, in particular to a step-by-step locking device for connector plugs of electric vehicles. Background technique [0002] At present, with the huge demand for new energy vehicles in the world, the field of electric vehicles is developing rapidly. It can be said that electric vehicles and related industries, such as electric stations, have a bright future in China. However, in the current situation, although the country has vigorously advocated it, and various enterprises have high popularity, a series of technical problems, such as the difficulty of charging, have become a bottleneck that restricts the entry of electric vehicles into ordinary people's homes in the short term.

Problems solved by technology

However, in the current situation, although the country has vigorously advocated it, and various enterprises have high popularity, a series of technical problems, such as the difficulty of charging, have become a bottleneck that restricts the entry of electric vehicles into the homes of ordinary people in the short term.

But charging safety is one of the issues limiting the development of rechargeable electric vehicles

At present, one of the commonly used charging protection measures is to install protective components on the connector port of electric vehicles, mostly openable cover-shaped components. However, if the locking and unlocking of such cover-shaped components do not use other auxiliary devices, the user Still facing power hazards

However, the existing step-by-step locking device has a relatively complicated structure, is difficult to use, and has high maintenance costs.
