Locking mechanism with secondary locking function

Abstract

The invention discloses a locking mechanism with a secondary locking function. The locking mechanism comprises a locking cavity and a cover plate. The cover plate and the locking cavity are connected in a detachable manner. The locking mechanism also comprises a primary locking block, a secondary locking block and a button. An elastic part is disposed inside the button. A primary slide rail is disposed in the locking cavity. The primary locking block is provided with a first guide rail. A secondary slide rail is disposed in the locking cavity. The secondary locking block is provided with a first slideway. The cover plate is equipped with a button through hole. The locking mechanism is prevented from losing the locking function due to aging of materials when being used for a long period of time, is capable of rotating about a contact member in a locking state, and has a secondary locking function to be prevented from automatically unlocked by accident.

Description

technical field [0001] The invention relates to a locking mechanism of an electrical connector in the electrical fields of new energy vehicles, industrial equipment, urban rail and railway vehicles, in particular to a locking mechanism of an electrical connector with a secondary locking function. Background technique [0002] In modern industrial electrical systems, the use of electrical connectors is becoming wider and wider, and the number is increasing. The functional requirements of the connectors are also increasing, and the use conditions are becoming more and more harsh. A reliable locking function can be realized under the use environment, so as to meet the use requirements of the connector. [0003] The traditional electrical connector locking structure is usually realized through the connector locking structure, so that the force of the connector locking is all loaded on the locking structure of the connector. In this way, the material requirements for the connecto...

Problems solved by technology

[0003] The traditional electrical connector locking structure is usually realized through the connector locking structure, so that the force of the connector locking is all loaded on the locking structure of the connector. In this way, the material requirements for the connector are very high. During long-term use, the locking function of the connector may be invalid due to the aging of the material; the traditional locking structure of the connector usually makes the plug and socket of the connector relatively fixed, and the relative rotation between the plug and the socket cannot occur, so that It is difficult to wire on site; the traditional connector locking structure usually only has one locking function, and in an accident, the connector may be automatically unlocked, and eventually the locking function of the connector will be invalid;

[0004] It can be seen that the traditional locking structure of electrical connectors cannot meet the industrial requirements for connector locking, especially the use requirements of new energy vehicles for connector locking.
