[0022] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] Please refer to Figure 1-5As shown, a connector with a secondary unlocking structure comprises a socket 1 and a plug 2, wherein the plug 2 is detachably connected to the socket 1 via a first fixing portion 3 and a second fixing portion 4;

[0024] Wherein, an unlocking component 5 for unlocking the first fixing part 3 and the second fixing part 4 is also included.

[0025] Specifically, the socket and the plug are fixed and locked by the first fixing part and the second fixing part, and a secondary unlocking component is added to the first fixing part and the second fixing part. When the unlocking component is used to unlock the first fixing part, the unlocking component will press the second fixing part at the same time, and unlocking can be achieved by pulling the unlocking component, so that when the first fixing part and the second fixing part are pulled and unlocked without using the unlocking component, the first fixing part and the second fixing part cannot be unlocked by hand, that is, unlocking is convenient and quick, and safety performance is improved.

[0026] In this embodiment, the first fixing portion 3 includes side buckles 301 disposed on both sides of one end of the socket 1 for fixing, and also includes a buckle 302 disposed at one end of the plug 2 and buckled with the side buckles 301;

[0027] The side buckle 301 is provided with a plug hole 6, and the unlocking component 5 includes pins 501 that can be inserted into the plug holes 6 on both sides.

[0028] Specifically, the buckle extends into the side buckle and engages with the inner wall of the side buckle to complete the fixed connection between the socket and the plug. The plug pin is inserted into the socket of the side buckle and pressed downward. The plug pin applies inward pressure to the buckle to disengage the buckle from the inside of the side buckle to complete the unlocking action. The whole process is convenient and quick; the opposite sides of the lower ends of the two plug feet are designed with guiding slopes.

[0029] In this embodiment, the second fixing portion 4 includes a hook 401 rotatably arranged on the outer periphery of the end of the plug 2, and a protruding snap ring 402 is provided on the outer periphery of the end of the socket 1; wherein, the unlocking component 5 is also provided with a pressing portion 502, and the pressing portion 502 is placed on the upper part of the hook 401.

[0030] Specifically, rotate the hook on the plug to engage the snap ring of the socket, insert the pin into the jack of the side buckle, and press the pin downward to unlock the first fixing part. When pressing downward for the second time, the pressing part presses and rotates the tail of the hook so that the front end of the hook engaged on the snap ring is pressed and lifted, that is, the hook is disengaged from the snap ring, completing the unlocking action.

[0031] In this embodiment, opening grooves 8 are provided on both sides of the buckle 302 , and the opening grooves 8 are located at the outer periphery of the plug 2 , so that the buckle 302 is an elastic buckle.

[0032] Specifically, the open groove design on both sides of the buckle makes the buckle an elastic buckle with elastic deformation directly set on the outer periphery of the plug. The elastic buckle is easier to be inserted into the side buckle for clamping, and when the unlocking part is pressed downward, the buckle is easier to detach from the inner wall of the side buckle, and unlocking is more labor-saving and quick.

[0033] In this embodiment, a plurality of limiting protrusions 9 are provided on the outer periphery of the socket 1 , and a limiting groove 10 cooperating with the limiting protrusions 9 is provided on the inner wall of the plug 2 .

[0034] Specifically, the cooperation between the limiting protrusion and the limiting groove can make it easier for the buckle to cooperate with the side buckle. Furthermore, the limiting protrusion and the limiting groove can also prevent the socket and the plug from rotating relative to each other, thus playing a role of limiting and fixing.

[0035] In this embodiment, a slot 11 is provided on the outer periphery of the plug 2 , and a rotating shaft 12 is inserted through the end of the hook 401 . Both ends of the rotating shaft 12 are rotatably inserted on both sides of the slot 11 .

[0036] In this embodiment, a protrusion 13 is disposed in the slot 11 , and the protrusion 13 is disposed below the tail of the hook 401 . An indented hole 14 is disposed on the hook 401 .

[0037] Specifically, when the pressing part is pressed, the recessed hole on the inner side of the pressing part is buckled on the raised part, that is, the raised part is placed in the recessed hole, and the raised part cooperates with the recessed hole to play the role of fixing the hook. When the second fixing part is unlocked, the buckle can be prevented from automatically rotating downward and buckling on the snap ring.

[0038] The added unlocking component can not be unlocked by pressing the second fixing part on the connector alone without using the unlocking component; when the unlocking component is used, the unlocking action of the unlocking component and the non-unlocking component can be completed in one step, which is convenient and quick.

[0039] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other principles and basic structures that are the same or similar to those of the present application are within the protection scope of the present application.
