Description

Technical Field

[0001] This utility model relates to the field of electrical connections, and in particular to a highly protected charging adapter with reliable port locking. Background Technology

[0002] When charging new energy vehicles, a charging adapter is used to switch between the electrical and mechanical interfaces of the vehicle's dual-head charging gun and the household charging socket. Currently, the adapter uses a simple plastic cover as a dust cover and lacks a mechanical locking structure during charging. Its drawbacks are: firstly, the dust cover will wear down from repeated opening and closing, causing it to loosen and easily fall off the adapter, reducing or eliminating its protective performance; secondly, during the high-voltage charging process of the vehicle, without a mechanical locking structure, the charging port locking is unreliable, and the charging gun and adapter can be manually separated, resulting in poor safety protection performance.

One end of the opening and closing end 22 is provided with a longitudinal channel 221 and an opening and closing channel 222 that penetrates the longitudinal channel 221 vertically.

[0040] The rotating part 3 is connected to the rotating groove 101 at both ends and the rotating end 21 passes through the middle. The rotating groove 101 is connected in the middle by the reset spring 6, so as to realize the automatic opening of the protective cover 2 when it is not locked.

[0041] The locking part 4 has a locking fastener 41 that is slidably connected to the longitudinal channel 221 and connected to the inner end of the longitudinal channel 221 through a tension spring 43. The lower end of the unlocking part 42 of the locking part 4 passes through the opening and closing channel 222 and is fixed in the middle of the locking fastener 41. Pulling the unlocking part 42 causes the outer locking pin 411 of the locking fastener 41 to exit the locking hole 103, thus opening the cover. Rotating the protective cover 1 causes the outer locking pin 411 of the locking fastener 41 to contact the end face of the locking hole 103. After compressing the tension spring 43, the outer locking pin 411 retracts and smoothly extends into the locking hole 103. Then, the tension spring 43 resets the outer locking pin 411, thus locking the cover.

[0042] The mechanical lock 5 enters and exits the positioning hole 011 of the charging gun 01 to achieve charging locking or unlocking.

[0043] The outer locking pin 411 extends into the locking hole 103, the protective cover 2 seals and closes the insertion interface 100, the outer locking pin 411 moves out of the locking hole 103, and the protective cover 2 automatically rotates to expose the insertion interface 100 under the action of the return spring 6.
