Description

Technical Field

[0001] The utility model relates to the field of new energy charging, and more specifically, the utility model relates to a charging gun structure fixed by an insulator buckle. Background Art

[0002] An AC charging gun is a device required for a new energy vehicle to charge. During use, the AC charging gun must ensure its insulation and safe use performance, otherwise safety accidents will occur.

[0003] In the prior art, the front-end assembly of the plug of an AC charging gun generally includes a front plug mounting plate, a rear plug mounting plate, jacks, jack seals, mounting plate seals, a PCB board, PCB board fixing screws, and mounting plate fixing screws. And the installation mainly uses fixing screws for fixation. However, in the prior art, there are too many structural parts for fixing the jacks through the front plug mounting plate and the rear plug mounting plate, which leads to too many installation procedures and too high costs. Summary of the Utility Model

[0004] The utility model overcomes the deficiencies of the existing charging gun with a large number of parts and complex assembly, and provides a charging gun structure fixed by an insulator buckle, hoping to solve the above problems.

[0005] A charging gun structure fixed by an insulator buckle includes a housing seal ring, a plug housing, functional jacks, and a rear insulator for board pins;

[0006] The front part of the plug housing has a seal ring installation position, the plug housing is provided with jack installation holes, and the plug housing has a buckle structure matching the rear insulator for board pins;

[0007] The housing seal ring is installed on the seal ring installation groove of the plug housing;

[0008] The functional jacks are installed in the jack installation holes of the plug housing;

[0009] The rear insulator for board pins is fixed to the plug housing by a buckle, and the rear insulator for board pins fixes the functional jacks in the jack installation holes.

[0010] The utility model realizes the fixation between the plug housing and the rear insulator for board pins through the buckle structure, and fixes the functional jacks in the jack installation holes, avoiding the front-back movement of the functional jacks in the jack installation holes, thereby reducing the use of fixing parts such as screws, making the parts fewer, and the structure and assembly simpler.

[0011] A further technical solution is that the number of the buckle structures is more than 2.

[0012] A further technical solution is that the number of the buckle structures is 3;

[0013] One of the buckle structures is disposed above the plug housing, and the other two buckle structures are disposed on the left and right sides of the plug housing.

[0014] Compared with one buckle structure, using three buckle structures can balance the complexity of parts and the assembly stability effect.

[0015] A further technical solution is that the buckle structure includes an elastic buckle and a through hole;

[0016] The elastic buckle is disposed on the rear insulator of the board pin;

[0017] The through hole is disposed on the plug housing and corresponds to the position of the elastic buckle.

[0018] The elastic buckle has a good disassembly and fixing effect. If disassembly is required, the elastic buckle can be toggled through the through hole, so that the buckle structure is unlocked and the disassembly is completed.

[0019] A further technical solution is that the charging gun structure further includes a PCB board;

[0020] Fixing buckles and / or limiting slots for cooperating with the PCB board are disposed on the rear insulator of the board pin;

[0021] The PCB board is fixedly installed on the rear insulator of the board pin.

[0022] In the prior art, the PCB board is also fixed using fixing parts such as screws. Fixing the PCB board to the rear insulator of the board pin using fixing buckles that cooperate with the PCB board can reduce the number of installation parts and steps, and the rear insulator of the board pin abuts against the functional jack, further stabilizing the PCB board.

[0023] A further technical solution is that the PCB board includes a temperature sensing PCB board and a resistance PCB board.

[0024] A further technical solution is that the functional jacks include a ground jack, a power jack, and a signal jack.

[0025] Compared with the prior art, the present utility model has at least the following beneficial effects: The present utility model realizes the fixation between the plug housing and the rear insulator of the board pin through the buckle structure, and fixes the functional jacks in the jack mounting holes. Further, the present utility model fixes the PCB board to the rear insulator of the board pin by providing fixing buckles on the rear insulator of the board pin that cooperate with the PCB board, improving the reliability of the pin fixation, reducing the number of parts, integrally installing and fixing the PCB board, with simple installation, and at the same time reducing the manufacturing cost.
