[0025] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] As attached Figure 1-7As shown, an integrated locking structure includes a plug housing 1, a socket housing 2, and a secondary locking slider 3. The plug housing 1 is adapted to and connected to the socket housing 2, and the socket housing 2 is locked by the secondary locking slider 3.

[0027] In a preferred embodiment of this utility model, the plug housing 1 is provided with a secondary locking slider limiting part 11 at the top, the upper part of the plug housing 1 includes a locking lever 12, the locking lever 12 is provided with a locking hook 121, a secondary locking slider receiving cavity 122, the tail of the secondary locking slider receiving cavity 122 is provided with a secondary locking slider anti-retraction groove 1221, a secondary locking slider guide groove 1222, the middle of the secondary locking slider receiving cavity 122 is provided with a secondary locking slider limiting post 1223, the two sides of the middle of the secondary locking slider receiving cavity 122 are provided with a secondary locking slider anti-misoperation support platform 1224, and the head of the secondary locking slider receiving cavity 122 is provided with a secondary locking slider limiting groove 1225;

[0028] As a preferred embodiment of the present utility model, the upper part of the socket housing 2 is provided with a locking bracket 21;

[0029] As a preferred embodiment of this utility model, the head of the secondary locking slider 3 is provided with a secondary locking slider cantilever nose 31, the upper part of the tail of the secondary locking slider 3 is provided with a secondary locking slider unlocking part 32, the middle of the tail of the secondary locking slider 3 is provided with a secondary locking slider anti-accidental pressure blocking side wing 33, the lower part of the tail of the secondary locking slider 3 is provided with a secondary locking slider reverse spring tongue 34; and the lower sides of the tail of the secondary locking slider 3 are provided with secondary locking slider guide posts 35.

[0030] In use: The locking hook 121 on the plug housing 1 and the locking bracket 21 on the socket housing 2 are engaged through a lever structure, thereby enabling the plug and socket to be inserted and separated, thus effectively achieving the locking function;

[0031] The secondary locking slider 3 is assembled in the secondary locking slider receiving cavity 122 of the plug housing 1. Its tail works together with the tail of the locking lever 12 to separate the locking hook 121 from the locking platform 21. This not only simplifies the pressing part, but also increases the contact area of ​​its unlocking part. When unlocking, the thumb makes effective contact with the unlocking part, which meets the ergonomic requirements and facilitates manual unlocking operation.

[0032] The secondary locking slider reverse spring tongue 34 cooperates with the secondary locking slider anti-removal groove 1221 of the plug housing 1, and the secondary locking slider cantilever hanger 31 cooperates with the secondary locking slider limiting groove 1225 of the plug housing 1. The two work together to fix the secondary locking slider 3 in the plug housing 1, effectively preventing the secondary locking slider 3 from falling out of the plug housing 1 due to excessive force or the secondary locking slider 3 from being accidentally pushed in and locked when the head is not inserted.

[0033] The secondary locking slider cantilever hanger 31 cooperates with the locking platform 21, and the secondary locking slider unlocking part 32 cooperates with the secondary locking slider limiting part 11. The two work together to achieve secondary locking of the head seat. The secondary locking slider anti-accidental pressure blocking side wing 33 cooperates with the secondary locking slider anti-accidental pressure support platform 1224 of the plug housing 1, which effectively prevents the main lock from failing when the secondary locking slider 3 is not unlocked due to accidental pressing of the unlocking part.

[0034] In summary, compared with the prior art, this utility model has the advantages of reliable structure and easy operation, and is particularly suitable for the use requirements of electrical connectors in new energy vehicles, thus having high application value.

[0035] During insertion, push the plug housing 1 forward. The locking lever 12 slides along the wedge-shaped platform of the locking platform 21. When a "click" sound is heard, it indicates that the plug housing 1 and the socket housing 2 are locked. At this time, the locking hook 121 is engaged with the locking platform 21. The secondary locking slider cantilever nose 31 is now directly above the locking platform 21. Continue to push the secondary locking slider 3 forward. The secondary locking slider cantilever nose 31 moves forward in a straight line. The secondary locking slider guide post 35 is engaged in the secondary locking... The slider slides in the guide groove 1222 until the secondary locking slider guide post 35 interferes with the secondary locking slider limit post 1223 on the plug housing, thus achieving secondary locking of the locking structure. At this point, the plug housing 1 and the socket housing 2 are locked together. At this time, the secondary locking slider anti-accidental pressure blocking wing 33 cooperates with the secondary locking slider anti-accidental pressure support platform 1224 on the plug housing, effectively preventing the main lock from failing when the secondary locking slider is not unlocked due to accidental pressing of the unlocking part 32.

[0036] When unlocking, pull the secondary locking slider 3 backward until its reverse spring 34 interferes with the anti-removal groove 1221 of the secondary locking slider of the plug housing 1. At this time, the reverse spring 34 cooperates with the anti-removal groove 1221 of the secondary locking slider of the plug housing 1, effectively preventing the secondary locking slider 3 from falling out of the plug housing 1 due to excessive force. Then press the unlocking part 32 of the secondary locking slider and drag it backward until the plug housing 1 and the socket housing 2 are separated. At this point, the unlocking of the plug housing 1 and the socket housing 2 is completed.

[0037] The beneficial effects of this utility model are as follows: while retaining the primary and secondary locking structure of the electrical connector, the pressing part is simplified, making the unlocking operation easier. At the same time, the secondary locking slider is effectively fixed inside the plug housing, preventing the secondary locking slider from falling out of the plug housing due to excessive pulling force. In summary, this utility model solves the problem of the secondary locking slider easily falling out during unlocking of existing electrical connectors, improves the structural reliability and unlocking operability of the electrical connector, and is particularly suitable for the use requirements of electrical connectors in new energy vehicles, and has high application value.

[0038] Although the present invention has been described herein with reference to illustrative embodiments, the above embodiments are merely preferred embodiments of the present invention, and the implementation of the present invention is not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
