Embodiment Construction

[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0030] In a specific embodiment, such as Figure 1-3 As shown, a secondary locking and delayed unlocking structure of the present invention includes a socket housing 1, a plug housing 2 and a secondary locking slider 3, the socket housing 1 and the plug housing 2, the plug The housing 2 and the secondary locking slider 3 are detachably connected; one side of the plug housing 2 protrudes from a rectangular cavity, and the outer surface of the cavity is connected...

Abstract

The invention discloses a secondary locking and delayed unlocking structure. The secondary locking and delayed unlocking structure comprises a socket shell, a plug shell and a secondary locking sliding block, wherein the socket shell is detachably connected with the plug shell, the plug shell is detachably connected with the secondary locking sliding block. The secondary locking and delayed unlocking structure provided by the invention has the advantages that a separation process of a plug and a socket of a high voltage connector is split into three steps, separation time difference of the power connector assembly and a signal connector assembly is prolonged, the power connector assembly is guaranteed to be disconnected in advance when the power connector assembly is completely separated,and the problems that the arc discharge phenomenon can be easily caused as the plug and the socket of an existing high voltage connector are separated too fast and damage is caused to the power connector assembly and human body of an operator are solved; and a backstop structure is arranged between the secondary locking sliding block and the plug shell in the invention, before the plug is not inserted into the socket, the secondary locking sliding block cannot be pushed into the plug shell and is in an unlocked state all the time, and only after the plug and the socket successively complete delayed locking and primary locking, the secondary locking sliding block can be pushed into the plug shell.

Description

technical field [0001] The invention relates to the field of high-voltage electrical connectors, in particular to a secondary locking and time-delayed unlocking structure. Background technique [0002] The electrical connector is generally composed of a plug and a socket. The reliable connection between the plug and the socket is realized through the locking structure. The power connector in the electrical connector can only be contacted after the plug and the socket are mated. High-voltage electrical connectors usually also have a high-voltage interlock function, that is, after the physical connection of the power connector is completed, the signal connector needs to control its conduction, and then the high-voltage circuit can be energized; similarly, after disconnecting the high-voltage When connecting the circuit, the signal connector should be disconnected first, the current of the high-voltage line should be cut off, and then the connection of the power connector shoul...
