[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0027] like Figures 1-8 As shown, the utility model provides a plug-in connector with a locking element, comprising a plug and a socket 1 that are plugged into each other, wherein the socket 1 is provided with a locking receiving groove 2 that opens toward the plug, and the locking receiving groove 2 is provided with a locking portion 3.

[0028] The plug is provided with a locking element comprising a locking member 4, an operating rod 5, and an elastic member 6 connected between the locking member 4 and the operating rod 5. The plug is provided with an operating slot 7 through which the operating rod 5 can extend and move, and a locking extension hole 8 through which the locking member 4 can extend and move. The extended section of the locking member 4 is provided with a locking portion 9 that opposes the locking portion 3. The operating rod 5 can move up and down within the operating slot 7, and the locking member 4 can move up and down within the locking extension hole 8. The elastic member 6 has a certain elasticity. When the operating rod 5 is pressed, the elastic member 6 deforms and drives the locking member 4 downward. Due to the presence of the elastic member 6, the locking portion 9 on the locking member 4 deflects upon contact with the locking portion 3, ultimately locking with the locking portion 3.

[0029] When the plug is inserted into the socket 1 , the locking member 4 extends into the locking receiving groove 2 , and the locking portion 9 is locked with the locking portion 3 to connect the plug and the socket 1 together, with high installation efficiency.

[0030] When it is necessary to unplug the plug from the socket 1, the operating lever 5 is pressed, and the operating lever 5 activates the locking member 4 through the elastic member 6, and the locking portion 9 is unlocked from the locking portion 3 to unplug the plug from the socket 1. The operating lever 5 is released, and the elastic member 6 resets the locking member 4 and the operating lever 5, making the unlocking operation convenient.

[0031] The operating rod and the locking member of the utility model form a lever, and the elastic member forms the fulcrum of the lever. The operating rod and the locking member can be deflected around the elastic member, that is, the lever principle is used to achieve rapid locking and unlocking functions to complete the plugging and unplugging of the connector.

[0032] Preferably, a first fixing portion 10 is provided on the end of the elastic member 6 away from the operating rod 5, a first fixing groove 11 is provided on the plug for inserting the first fixing portion 10, a second fixing portion 12 is provided on the end of the locking member 4 away from the locking portion 4, and a second fixing groove 13 is provided on the plug for inserting the second fixing portion 12. The plug includes a cover plate 14 and a main body 15 that are plugged into each other. One end of the cover plate 14 is provided with a plug-in portion 16 for plugging into the socket 1, and the other end of the cover plate 14 is provided with the first fixing groove 11 and the locking protrusion hole 8. The main body 15 is provided with the operating groove 7 and the second fixing groove 13. When the locking member 4, elastic member 6, and operating rod 5 are designed as an integrated structure, the cover plate 14 and the main body 15 are of a separate structure, and a movable space 17 is formed in the cover plate 14 and the main body 15 to accommodate the elastic member 6, the operating rod 5, and the locking member 4. The movable space 17 is connected to the first fixing groove 11, the second fixing groove 13, the operating groove 7, and the locking protrusion hole 8. During installation, first install the locking element on the main body 15, that is, the operating rod 5 is installed in the operating groove 7 and exposed outside the main body 15, and at the same time, the second fixing portion 12 on the locking member 4 is installed in the second fixing groove 13 and fixed, and then the cover 14 is plugged into the main body 15. At the same time, the first fixing portion 10 on the elastic member 6 is installed in the first fixing groove 11 and fixed, and the locking member 4 extends from the locking extension hole 8. Under normal circumstances, the upper surface of the locking member 4 is close to the upper wall of the locking extension hole 8, the elastic member 6 is in a free state, and the operating rod 5 exposes the operating groove 7. When the operating rod 5 is pressed downward, the operating rod 5 moves downward in the operating groove 7. Since the first fixing portion 10 of the elastic member 6 is fixed in the first fixing groove 11, the elastic member 6 is driven by the operating rod 5 to bend and elastically deform relative to the first fixing portion 10, thereby driving the locking member 4 to move downward. Since the second fixing portion 12 of the locking member 4 is fixed in the second fixing groove 13, the locking member 4 will also bend and elastically deform relative to the second fixing portion 12. When the operating rod 5 is released, the elastic member 6, the locking member 4 and the operating rod 5 are reset under the elastic force.

[0033] Preferably, the cover 14 and the main body 15 are connected by a snap-fit ​​structure. Specifically, a snap-fit ​​protrusion 18 is provided on the upper and lower surfaces of the cover 14, and a snap-fit ​​groove 19 matching the snap-fit ​​protrusion 18 is provided on the upper and lower walls of the main body 15. The snap-fit ​​protrusion 18 is snapped into the snap-fit ​​groove 19 to connect the cover 14 and the main body 15 together.

[0034] Preferably, a first support arm 20 and a second support arm 21 are connected between the elastic member 6 and the locking member 4. The locking member 4, the first support arm 20, and the second support arm 21 form a triangle with the locking member 4 as the base, and the first support arm 20 and the second support arm 21 are inclined in opposite directions relative to the locking member 4. When the operating lever 5 is pressed downward, the force of the operating lever 5 is transferred to the first support arm 20 and the second support arm 21. The first support arm 20 bends downward, and the second support arm 21 pushes the locking member 4 downward, thereby unlocking the locking portion 9 and the locking portion 3. Otherwise, the locking portion 9 returns to its original position.

[0035] Preferably, the first support arm 20 and the second support arm 21 are an integral structure with the elastic member 6 and / or the locking member 4. The first support arm 20 and the second support arm 21 can be an integral structure with the elastic member 6, or an integral structure with the locking member 4, or the four can be an integral structure.

[0036] Preferably, at least two of the locking member 4, the operating rod 5 and the elastic member 6 are an integral structure; the locking member 4, the operating rod 5 and the elastic member 6 can be a split structure; any two of the locking member 4, the operating rod 5 and the elastic member 6 can be an integral structure; or the locking member 4, the operating rod 5 and the elastic member 6 can be an integral structure.

[0037] Preferably, the locking member 4 is provided with a limiting step 22 which is limited inside the locking extension hole 8, so that the locking member 4 can only move up and down along the locking extension hole 8 under the drive of the operating rod 5 and cannot extend out of the plug.

[0038] Preferably, the locking portion 3 is a locking hole, and the locking portion 9 is a locking protrusion, which is snapped into the locking hole to achieve locking of the plug and the socket 1 after being plugged in. The locking portion can also be a locking protrusion, and the locking portion is still a locking protrusion, and the locking protrusion passes over the locking protrusion and is snapped onto the locking protrusion to achieve locking of the plug and the socket 1 after being plugged in.

[0039] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and the embodiments. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
