Description

Technical Field

[0001] This utility model relates to the field of new energy charging guns, specifically a new energy charging gun. Background Technology

[0002] A charging gun is a device used to charge new energy vehicles. Traditional new energy charging guns require a protective sleeve to protect the plug, which is then removed during charging. The diameter of the charging gun's wiring harness varies depending on the vehicle model; producing a separate protective sleeve for each charging gun would significantly increase production costs.

[0003] Therefore, it is necessary to provide a new energy charging gun. Summary of the Invention

[0004] This utility model provides a new energy charging gun that effectively solves the problem of high cost of existing charging gun protective covers.

[0005] The technical solution adopted in this utility model is:

[0006] A new energy charging gun includes a charging gun and a protective sleeve mechanism. The charging gun includes a shell, a control module disposed within the shell, a plug disposed at one end of the shell and electrically connected to the control module, and a wire harness passing through the shell and connected to the control module. The protective sleeve mechanism includes a plastic collar, a protective cover for sealing the plug, and a connecting rope connecting the plastic collar and the protective cover. The plastic collar includes a ring body connected to the connecting rope and several protrusions circumferentially disposed on the inner side of the ring body. The protrusions abut against the wire harness, and the distance between two protrusions that are centrally symmetrical about the center of the ring body is less than the diameter of the wire harness.

[0007] Furthermore, the protective cover includes a cover body with an opening, a flange on the outer wall of the opening of the cover body, and inclined bosses symmetrically arranged on both sides of the cover body, the inclined bosses being inclined towards the opening side.

[0008] Furthermore, one end of the connecting rope is connected to the flange.

[0009] Furthermore, the boss is a conical boss, which tapers towards the center of the ring body.

[0010] Furthermore, the cross-sections of both the ring body and the connecting rope are rectangular or circular.

[0011] The beneficial effects of the utility model are: by utilizing the deformable feature of the boss, wires of different diameters can generate friction with the boss after passing through the ring body, thereby reducing production costs. Attached Figure Description

[0015] 13. Wiring harness; Detailed Implementation

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 and Figure 2 As shown, the new energy charging gun provided in the embodiment of this application includes a charging gun 1 and a protective sleeve mechanism 2. The charging gun 1 includes a housing 11, a control module disposed inside the housing 11, a plug 12 disposed at one end of the housing 11 and electrically connected to the control module, and a wire harness 13 passing through the housing 11 and connected to the control module. The protective sleeve mechanism 2 includes a plastic collar 21, a protective cover 22 for sealing the plug 12, and a connecting rope 23 connecting the plastic collar 21 and the protective cover 22. The plastic collar 21 includes a ring body 211 connected to the connecting rope 23 and several protrusions 212 circumferentially disposed on the inner side of the ring body 211. The protrusions 212 abut against the wire harness 13, and the distance between two protrusions 212 that are centrally symmetrical about the center of the ring body 211 is less than the diameter of the wire harness 13.

[0018] In actual use, when the charging gun 1 is idle, the protective cover 22 is placed on the plug 12. When the charging gun 1 needs to be used, the protective cover is pulled off the plug 12, allowing it to suspend from the wire harness 13 via the connecting rope 23 and the collar. The same batch of protective cover mechanisms 2 can be used for different models of wire harness 13 because the distance between the two centrally symmetrical bosses 212 is less than the minimum diameter of the wire harness 13 in the industry. The bosses 212 on the ring body 211 have a deformation function, generating sufficient friction with wire harnesses 13 of different diameters, thus ensuring that the ring body 211 does not slide freely on the wire harness 13.

[0019] In the above design, the deformable feature of the boss 212 can be utilized so that wire harnesses 13 of different diameters can generate friction with the boss 212 after passing through the ring body 211, thereby reducing production costs.

[0020] Specifically: such as Figure 2 As shown, the protective cover 22 includes a cover body 221 with an opening, a flange 222 on the outer wall of the opening of the cover body 221, and inclined bosses 223212 symmetrically arranged on both sides of the cover body 221, wherein the inclined bosses 223212 are inclined toward the opening side.

[0021] In actual use, the protective cover 22 is connected to the flange 222 via the connecting rope 23. When it is necessary to remove the protective cover 22, the protective cover 22 is removed by applying the fingers to the inclined boss 223212.

[0022] In the above design, the structural design and specific implementation of the protective cover 22 can effectively enable the quick removal of the protective cover 22.

[0023] Specifically: such as Figure 2 As shown, one end of the connecting rope 23 is connected to the flange 222.

[0024] In the above design, the connecting rope 23 is connected to the flange 222, which can achieve greater stability after the protective cover 22 is connected.

[0025] Specifically: such as Figure 2 As shown, the boss 212 is a conical boss 212, which tapers towards the center of the ring body 211.

[0026] In the above design, the concave end of the tapered boss 212 deforms after contacting the wire harness 13, so that the tapered boss 212 deforms and then rubs against the wire harness 13 through the end face of the tapered boss 212, thereby overcoming the movement of the collar along the wire harness 13, so that the collar can be adapted to wire harnesses 13 of different specifications in the field of charging gun 1.

[0027] Specifically, the cross-sections of the ring body 211 and the connecting rope 23 are both rectangular or circular.

[0028] In the above design, the structural design and specific implementation of the ring body 211 facilitates processing.

[0029] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
