High-voltage connector assembly with triple lock

Abstract

The invention discloses a high-voltage connector assembly with a three-time lock. The high-voltage connector assembly comprises a connector male end, a connector shell, an unlocking sliding block anda spring bolt, according to the three-time locking mechanism, two-section type unlocking between the connector male end and the connector shell is achieved, the requirements of the market for distributed unlocking and mistaken unlocking prevention are met, the sliding type unlocking sliding block is adopted, and the hanging buckle boss of the spring bolt is prevented from being pressed under the condition of misoperation through the protection part of the sliding type unlocking sliding block; and during locking, the hanging buckle boss is lower than the second hanging buckle position, so thatmisoperation is further prevented. Compared with an existing secondary lock structure, the secondary lock structure has the advantage that unlocking can be completed only by adjusting the position ofthe unlocking sliding block without the help of extra tools. A protrusion is arranged in the middle of the spring bolt, the middle of the spring bolt is limited up and down through the connector shell, rear-end operation is prevented from affecting the front end, and locking reliability is improved.

Description

technical field [0001] The invention relates to the field of high-voltage connectors for automobiles, in particular to a high-voltage connector assembly with a triple lock. Background technique [0002] With the popularity of new energy vehicles, the application of high-voltage connectors is becoming more and more extensive. In the actual installation and maintenance process, although the existing high-voltage connector with a secondary lock structure avoids the situation that the connector is separated from the male terminal due to misoperation by personnel, it cannot meet the increasingly stringent market requirements. When the existing secondary lock structure is separated, it is impossible to first separate the connector and the male terminal signal line to make the vehicle electronic system respond, and then cut off the final connection between the connector and the male terminal. [0003] Chinese patent CN 111092329 A is a high-voltage connector assembly with a second...

Problems solved by technology

In the actual installation and maintenance process, although the existing high-voltage connector with secondary lock structure avoids the situation where the connector is separated from the male end due to misoperation by personnel, it cannot meet the increasingly stringent market requirements.

When the existing secondary lock structure is separated, it is impossible to separate the connector and the signal line of the male end first, so that the electronic system of the whole vehicle can respond, and then cut off the final connection between the connector and the male end

[0003] Chinese patent CN 111092329 A is a high-voltage connector assembly with a secondary lock. Although this structure can prevent personnel from disconnecting the male end and the female end by misoperation, it needs tools to unlock it; it is very inconvenient in actual operation
