Description

Technical Field

[0001] This utility model relates to the field of charging gun technology, specifically a charging gun tail cable fixing structure. Background Technology

[0002] With the popularization of new energy vehicles, their safety has become a major concern. Charging safety, as a crucial aspect of electric vehicle use, is particularly important. Within the charging safety system, the structural safety of the charging gun on the charging station is paramount. It must not only strictly comply with national standards but also significantly exceed them to address potential rough handling by end-users and prevent safety issues. The secure fixing of the charging gun's tail is also a critical factor in ensuring its safety. If the tail is not securely fixed, the cable may sway or be pulled during use, affecting its safety and potentially leading to charging malfunctions or accidents. Therefore, it is essential to prioritize the structural safety of the charging gun itself and the secure fixing of its tail to ensure the safety and reliability of the electric vehicle charging process. This paper proposes a charging gun tail cable fixing structure.

[0003] The existing charging gun tail cable fixing structure has relatively complex fixing parts and assembly structure, making it difficult to assemble. Furthermore, the complex assembly structure and manufacturing process are also relatively complicated, thus increasing production costs. Utility Model Content

[0005] (II) Technical Solution To achieve the above objectives, this utility model is implemented through the following technical solution: a charging gun tail cable fixing structure, including a gun head and a handle, wherein the gun head is fixedly connected to one side of the handle, and a multi-core cable is provided on the other side of the handle, a sealing ring is sleeved on the outside of the multi-core cable, the sealing ring is plugged into the inside of the handle, and a fixing mechanism is provided at the tail end of the handle. The fixing mechanism includes a wire clamping block, and there are two wire clamping blocks. Each of the two wire clamping blocks has a claw fixedly connected to one side. The handle has a rib groove on its tail end surface and a protruding rib fixedly connected to the tail end. The protruding rib is located on the outer side of the rib groove, and the claw engages with the rib groove on one side of the protruding rib.

[0006] Preferably, both of the wire clamping blocks have threaded holes on their surfaces, and there are two threaded holes, which are symmetrically distributed at the top and bottom of the wire clamping blocks.

[0007] Preferably, a screw is threadedly connected between the matching threaded holes of the two clamping blocks, and the screw is used to fix the two clamping blocks.

[0008] In this invention, a sealing ring is placed over the outside of the multi-core cable, and then the sealing ring and the multi-core cable are inserted into the handle. Then, two clamping blocks are fixed to the tail of the handle. During fixing, the claws are clamped inside the groove of the rib, and the protruding ribs prevent the claws from detaching from the handle, thereby preventing the clamping blocks from detaching from the handle. Then, screws are used to pass through the threaded holes to fix the two clamping blocks, thus fixing the multi-core cable to the tail of the charging gun using the clamping blocks.

[0009] Preferably, the inner surfaces of both clamping blocks are provided with anti-slip grooves, and the number of anti-slip grooves is set to multiple, and the multiple anti-slip grooves are evenly arranged among each other.

[0010] Preferably, anti-slip blocks are fixedly connected between the inner surfaces of the two clamping blocks. The anti-slip blocks are located on one side of the anti-slip groove, and multiple anti-slip blocks are provided, which are evenly arranged among each other.

[0011] Preferably, the plurality of anti-slip blocks and the plurality of anti-slip grooves are arranged in an alternating pattern on the side.

[0012] In this invention, the interlaced anti-slip blocks and anti-slip grooves inside the clamping block increase the friction between the multi-core cable and the clamping block, thereby better preventing the multi-core cable from sliding and fixing it more firmly.

[0013] (III) Beneficial Effects This utility model provides a cable fixing structure for the tail of a charging gun. It has the following advantages: (i) The charging gun tail cable fixing structure can fix the charging gun tail and the cable with two clamping blocks and screws. It uses fewer parts and has a simple structure, which simplifies the assembly process. The simple part structure also makes its processing process simple, thereby reducing production costs.

[0014] (ii) The cable fixing structure at the tail of the charging gun, through the setting of claws, inner groove of ribs, anti-slip blocks and anti-slip grooves, can make the cable clamping block and the handle tail more firmly fixed. Furthermore, the anti-slip blocks and anti-slip grooves can increase the friction between the multi-core cable and the cable clamping block, thereby better preventing the multi-core cable from sliding and fixing it more firmly.

[0018] See Figure 1-4 This utility model provides a technical solution: a charging gun tail cable fixing structure, the structure includes a gun head 1 and a handle 2. The gun head 1 is fixedly connected to one side of the handle 2. A multi-core cable 3 is provided on the other side of the handle 2. A sealing ring 4 is sleeved on the outside of the multi-core cable 3. The sealing ring 4 is plugged into the inside of the handle 2. A fixing mechanism 5 is provided at the tail end of the handle 2. The fixing mechanism 5 includes a wire clamping block 51. There are two wire clamping blocks 51. Each of the two wire clamping blocks 51 has a claw 52 fixedly connected to one side. The handle 2 has a rib groove 53 on its tail end surface. The handle 2 has a protruding rib 54 fixedly connected to its tail end. The protruding rib 54 is located on the outer side of the rib groove 53. The claw 52 engages with the rib groove 53 on one side of the protruding rib 54.

[0019] Each of the two wire clamping blocks 51 has a threaded hole 55 on its surface. There are two threaded holes 55, which are symmetrically distributed on the top and bottom of the wire clamping blocks 51.

[0020] Among them, the two wire clamping blocks 51 are connected by a screw 56 through their matching threaded holes 55. The screw 56 is used to fix the two wire clamping blocks 51.

[0021] The inner surfaces of the two clamping blocks 51 are provided with anti-slip grooves 57, and the number of anti-slip grooves 57 is set to multiple, and the multiple anti-slip grooves 57 are evenly arranged among each other.

[0022] Among them, anti-slip blocks 58 are fixedly connected between the inner surfaces of the two clamping blocks 51. The anti-slip blocks 58 are located on one side of the anti-slip groove 57. Multiple anti-slip blocks 58 are provided, and the multiple anti-slip blocks 58 are evenly arranged among each other.

[0023] Among them, multiple anti-slip blocks 58 and multiple anti-slip grooves 57 are arranged in an alternating pattern on the side.

[0024] Working principle: When fixing the tail of the charging gun, first, the sealing ring 4 is placed on the outside of the multi-core cable 3.

During fixing, the claws 52 are engaged inside the inner groove of the rib 53. The protruding ribs 54 prevent the claws 52 from disengaging from the handle 2, thereby preventing the wire clamping blocks 51 from disengaging from the handle 2. Finally, the two wire clamping blocks 51 are fixed by passing screws 56 through the threaded holes 55. The multi-core cable 3 is fixed to the tail of the charging gun by using the clamping block 51. The anti-slip sliders 58 and anti-slip grooves 57 inside the clamping block 51 can increase the friction between the multi-core cable 3 and the clamping block 51, thereby better preventing the multi-core cable 3 from sliding and fixing it more firmly. Similarly, when the clamping block 51 needs to be disassembled, the screw 56 is removed from the threaded hole 55, and then the clamping claw of the clamping block 51 is removed from the inner groove 53 of the rib. The operation is simple, convenient and quick.
