Technical Field

[0001] The utility model relates to the field of connectors, in particular to a locking structure of a connector. Background Art

[0002] Connectors are also called connectors, and are also called joints and sockets in China. They generally refer to electrical connectors. That is, devices that connect two active devices to transmit current or signals.

[0003] With the development of charging equipment, such as electric motorcycles, in order to ensure the safety of charging, a double-layer locking structure is generally set to prevent accidental unplugging, while also ensuring the stability of the female and male plugs. However, the existing double-layer locking structure generally uses a spring structure to achieve locking, and there are many assembly processes. Generally, a special spring slot is required to achieve the corresponding locking or unlocking. Utility Model Content

[0004] The main purpose of the utility model is to provide a locking structure of a connector, aiming to improve the existing locking structure, which has a simple structure and is convenient for assembly.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a locking structure of a connector, comprising:

[0006] A first insulator, a first shell on the outer peripheral wall of the first insulator, and a protruding hook is provided on the upper wall of the first shell;

[0007] A second insulator, wherein the outer peripheral wall of the second insulator is provided with a second shell matched with the first shell, the upper wall of the second shell is provided with a swinging bracket, and the lower wall of the bracket is provided with a stopper matched with the hook;

[0008] A slidably arranged stopper is provided between the second housing and the second insulator, and the stopper can move between a position for limiting the swing of the bracket and a position for unlocking the swing of the bracket.

[0009] When the bracket is swung to unlock, the blocking portion can be disengaged from the hook.

[0010] In the actual design of the technical solution of the utility model, the stop seat can be set at the position of the support arm of the bracket or at a position away from the blocking part, so as to limit the swing of the bracket. Of course, when the support arm is set at the rear end, the stop seat can also be set in the middle position of the bracket. Through the sliding setting of the stop seat, the hook and the blocking part are hooked with each other, and the first insulator and the second insulator are locked with each other, realizing the double-layer locking of the connector, thereby improving the charging safety.

[0018] like Figures 1 to 3 As shown, a locking structure of a connector includes:

[0019] A first insulator 1, a first shell 11 on the outer peripheral wall of the first insulator 1, and a protruding hook 3 is provided on the upper wall of the first shell 11;

[0020] A second insulator 12, wherein the outer peripheral wall of the second insulator 12 is provided with a second shell that matches the first shell, the upper wall of the second shell 21 is provided with a swinging bracket 4, and the lower wall of the bracket 4 is provided with a stopper 42 that matches the hook 3;

[0021] A slidable stopper 5 is provided between the second housing 21 and the second insulator 12. The stopper 5 can move between a position for limiting the swing of the bracket 4 and a position for unlocking the swing of the bracket 4.

[0022] When the bracket 4 is swung and unlocked, the blocking portion 42 can be separated from the hook 3 .

[0023] In the actual design, the stop seat 5 can be set at the position of the support arm 41 of the bracket 4 or at a position away from the stop part 42, so as to limit the swing of the bracket 4. Of course, when the support arm 41 is set at the rear end, the stop seat 5 can also be set at the middle position of the bracket 4. Through the sliding setting of the stop seat 5, the hook 3 and the stop part 42 are hooked with each other, and then the first insulator 1 and the second insulator 12 are locked with each other, and the double-layer locking of the connector is realized, thereby improving the charging safety.

[0024] Specifically, a support arm 41 connected to the second shell 21 is provided in the middle of the bracket 4. In actual settings, setting the support arm 41 in the middle of the bracket 4 can effectively improve the elastic stability of the swing of the bracket 4 and increase its service life.

[0025] In the embodiment of the utility model, the blocking portion 42 is arranged at the front end position of the bracket 4, and the stop seat 5 is slidably installed at the rear end part of the bracket 4 and abuts against its lower wall. The stop seat 5 is installed at the rear end position of the second shell 21, which can facilitate its installation and fixation.

[0026] The setting of the double-layer locking structure has great reference significance and is widely applicable to the locking structure of connectors.

[0027] In the embodiment of the utility model, the bracket 4 and the second shell 21 are integrally injection-molded, thereby making the structure simpler and simplifying the assembly process.

[0028] Specifically, the support arm 41 is arranged in a bent shape, and the upper wall of the rear end of the bracket 4 is provided with a pressing portion 43, and the pressing portion 43 is provided with anti-slip grooves, thereby making the fulcrum more stable. Therefore, when pressure is applied to the pressing portion 43, the front end of the bracket 4 can be tilted and the stop seat 5 can be forced to move backward, thereby achieving unlocking.

[0029] In the embodiment of the utility model, a plurality of guide grooves 61 are provided between the second insulator and the second shell 21 , and the stop seat 5 is provided with a guide portion 62 matched with the guide groove 61 , and the guide portion 62 located in the middle is provided with abutting portion against the lower wall of the pressing portion 43 .

[0030] Specifically, elastic arms 7 are provided on both sides of the stop seat 5, and slots 71 matching with the elastic arms 7 are provided on both sides of the second shell 21. The ends of the elastic arms 7 can be inserted into the slots 71. The setting of the elastic arms 7 allows the stop seat 5 to slide elastically and achieve elastic limiting at the same time.

[0031] In the embodiment of the utility model, the front end of the abutment portion is provided with an inclined surface 81, and the rear end of the stop seat 5 is provided with a lever portion 82 extending upward. The setting of the lever portion can facilitate the sliding of the stop seat 5 and pull it to a position away from the pressing portion 43.

[0032] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
