Description

Technical Field

[0001] This utility model relates to the field of new energy, specifically a quick-install charging gun housing that can secure cables. Background Technology

[0002] A charging gun is a mechanism used to charge new energy vehicles. An electrical module is installed inside the charging gun, and the wiring harness of this module needs to be led out of the charging gun to connect to the charging pile. During the process of placing and removing the charging gun, the wiring harness may loosen relative to the outer casing while being dragged, causing the wiring harness to detach from the electrical module. To prevent the wiring harness from detaching from the electrical module, a common method is to install a clamping mechanism inside the outer casing to fix the wiring harness in place. The clamping mechanism often uses a clamp-like design to fix the wiring harness to the outer casing, thus making the wiring harness and the outer casing an integral part and reducing the probability of detachment. However, the current clamp-like design requires first fixing the wiring harness to the clamp, and then using bolts or other connectors to fix the clamp to the outer casing. Furthermore, existing components such as the tail plug also need to be fixed to the outer casing with bolts, making the entire assembly process inconvenient and inefficient.

[0003] For example, Chinese patent CN220066718U discloses a cable clamp and a charging gun. The cable clamp includes a clamp and an elastic plate. The clamp has a through-hole. The elastic plate is connected to the wall of the through-hole and has a deformable surface parallel to the through-hole. The deformable surface divides the through-hole into a wire-passing hole and a deformation hole. The aforementioned cable clamp includes a first clamp and a second clamp, which need to be fixed with bolts. This is a traditional clamp-type clamp. Such clamps are inconvenient to assemble with a charging gun and require separate fixing to the wire harness before assembly with the charging gun housing, resulting in low assembly efficiency.

[0004] Therefore, it is necessary to provide a quick-release charging gun housing that can secure the cable. Utility Model Content

[0005] This utility model provides a quick-release charging gun housing that can secure cables, effectively solving the problems of inconvenient fixing and assembly of charging guns for wire harnesses.

[0006] The technical solution adopted in this utility model is:

[0007] A quick-release charging gun housing for securing cables includes a housing body with a cavity, a sealing ring, a wedge clamp, and a tail plug. The inner wall of the cavity has several bosses parallel to the extension direction of the housing, and an annular groove on the inner wall of the cavity. The tail plug includes a hollow plug with a through cavity and several buckles circumferentially disposed on the hollow plug. The buckles cooperate with the annular groove to fix the tail plug to the housing body. The two ends of the sealing ring abut against the bosses and the wedge clamp, respectively. The wedge clamp includes an annular body with both ends abutting against the sealing ring and the buckles, and several elastic claws circumferentially disposed on the side of the annular body opposite to the buckles. The hollow plug has a conical groove for abutting against the outer wall of the elastic claws, and the conical groove contracts away from the annular body.

[0008] Furthermore, the annular groove includes a bottom wall, a right side wall, and a left side wall, the right side wall being perpendicular to the bottom wall, and the left side wall being inclined away from the right side wall.

[0009] Furthermore, the inverted buckle includes a vertical surface that abuts against the right side wall and an inclined surface that abuts against the left side wall.

[0010] Furthermore, the elastic claw corresponds one-to-one with the inverted buckle, and the outer side of the elastic claw abuts against the inner wall of the inverted buckle.

[0011] Furthermore, the conical groove and the through cavity form a first annular step, and the end of the elastic claw abuts against the first annular step.

[0012] Furthermore, the inner wall of the shell body is provided with at least one horizontal groove, the inclined wedge clamp also includes a first protrusion provided on the side of the annular body, and the tail plug also includes a second protrusion provided on the side of the hollow plug. Both the first and second protrusions are engaged with the horizontal groove.

[0013] Furthermore, the sealing ring includes an annular ring body, several outer rubber rings arranged axially along the outer side of the annular ring body, and an inner rubber ring disposed inside the annular ring body. The outer rubber rings abut against the inner wall of the cavity, and the boss abuts against the annular ring body.

[0014] Furthermore, the end of the elastic claw is provided with texture.

[0015] Furthermore, the shell body and the boss are integrally formed.

[0016] The beneficial effects of this utility model are as follows: By using a wedge clamp to secure the wiring harness of the internal electrical module of the charging gun, the wiring harness will not move relative to the outer shell during the charging gun's placement and removal, thus preventing the wiring harness from falling off the electrical module. Furthermore, the entire housing mechanism does not require bolts or other fasteners to fix the tail plug to the housing body, making assembly convenient. Attached Figure Description

[0022] 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.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the quick-release charging gun housing for securing cables provided in the embodiments of this application includes a housing body 1 with a cavity, a sealing ring 2, a wedge clamp 3, and a tail plug 5. The inner wall of the cavity is provided with several bosses 4 parallel to the extension direction of the housing, and an annular groove 101 is provided on the inner wall of the cavity. The tail plug 5 includes a hollow plug 51 with a through cavity and several buckles 52 circumferentially disposed on the hollow plug 51. The buckles 52 cooperate with the annular groove 101 to fix the tail plug 5 to the housing body 1. The two ends of the sealing ring 2 abut against the bosses 4 and the wedge clamp 3, respectively. The wedge clamp 3 includes an annular body 31 with both ends abutting against the sealing ring 2 and the buckles 52, and several elastic claws 32 circumferentially disposed on the side of the annular body 31 opposite to the buckles 52. The hollow plug 51 is provided with a conical groove 501 for abutting against the outer wall of the elastic claws 32. The conical groove 501 contracts away from the annular body 31.

[0024] During actual assembly, the electrical module required for the charging gun is first installed into the housing body 1, and the wiring harness of the electrical module is led out of the cavity. Then, the sealing ring 2 and the wedge clamp 3 are installed, so that the wiring harness passes through the sealing ring 2 and the wedge clamp 3. Then, the tail plug 5 is installed, so that the buckle 52 of the tail plug 5 presses against the annular body 31, pushing the wedge clamp 3 and the sealing ring 2 to move in the housing body 1, so that the two sides of the sealing ring 2 abut against the boss 4 and the annular body 31 respectively. During the process of the wedge clamp 3 being pushed, the outer side of the elastic claw 32 abuts against the inner wall of the conical groove 501, so that several elastic claws 32 contract and clamp the wiring harness until the buckle 52 extends into the annular groove 101 to complete the assembly.

[0025] In the above design, the wire harness of the electrical module inside the charging gun can be secured by the wedge clamp 3, preventing the wire harness from moving relative to the outer shell during the charging gun's placement and removal, thus preventing the wire harness from falling off the electrical module. At the same time, the entire housing mechanism does not require bolts or other fasteners to fix the tail plug 5 to the housing body 1, making assembly convenient.

[0026] Specifically: such as Figure 2 As shown, the annular groove 101 includes a bottom wall, a right side wall 1012 and a left side wall 1011. The right side wall 1012 is perpendicular to the bottom wall, and the left side wall 1011 is inclined to the side away from the right side wall 1012.

[0027] It should be noted that, with Figure 2 For example, the sealing ring 2 is on the left side of the tail plug 5.

[0028] After actual assembly, the undercut 52 should abut against the left side wall 1011 and the right side wall 1012, so that the left side wall 1011 and the right side wall 1012 limit the undercut 52.

[0029] In the above design, the structural design of the annular groove 101 and the specific implementation method enable the fixing of the buckle 52.

[0030] Specifically: such as Figure 2 and Figure 3 As shown, the inverted buckle 52 includes a vertical surface that abuts against the right side wall 1012 and an inclined surface 521 that abuts against the left side wall 1011.

[0031] During actual assembly, the buckle 52 is pushed from right to left. After the inclined surface 521 contacts the left side wall 1011, it will slide relative to the left side wall 1011 until the vertical surface of the buckle 52 extends into the annular groove 101 and abuts against the right side wall 1012.

[0032] In the above design, the structural design and specific implementation of the undercut 52 and the annular groove 101 can effectively guide the undercut 52 during the assembly process of the undercut 52 and the annular groove 101, and prevent the left side wall 1011 from excessively hindering the movement of the undercut 52.

[0033] Specifically: such as Figure 1 , Figure 2 and Figure 3 As shown, the elastic claw 32 corresponds one-to-one with the buckle 52, and the outer side of the elastic claw 32 abuts against the inner wall of the buckle 52.

[0034] During actual assembly, after the outer side of the elastic claw 32 abuts against the inner wall of the buckle 52, the elastic claw 32 extends into the conical groove 501 as the buckle 52 pushes.

[0035] In the above design, the structural design and specific implementation of the elastic claw 32 and the inverted buckle 52 can limit the outer side of the elastic claw 32 and ensure the smooth movement of the elastic claw 32.

[0036] Specifically: such as Figure 2 and Figure 3 As shown, the conical groove 501 and the through cavity form a first annular step 502, and the end of the elastic claw 32 abuts against the first annular step 502.

[0037] During actual assembly, after the end of the elastic claw 32 abuts against the first annular step 502, it indicates that the relative position of the elastic claw 32 and the tail plug 5 meets the assembly requirements.

[0038] In the above design, the design of the first annular step 502 and the elastic claw 32, as well as the specific implementation method, can effectively achieve the positioning of the elastic claw 32 and the tail plug 5.

[0039] Specifically: such as Figure 4 As shown, the inner wall of the shell body 1 is also provided with at least one horizontal groove 102, such as... Figure 1 As shown, the inclined wedge clamp 3 also includes a first protrusion 33 disposed on the side of the annular body 31, and the tail plug 5 also includes a second protrusion 53 disposed on the side of the hollow plug 51. Both the first protrusion 33 and the second protrusion 53 are engaged with the horizontal groove 102.

[0040] During actual assembly, the first protrusion 33 slides along the first horizontal groove 102, and the second protrusion 53 slides along the second horizontal groove 102 until the wedge clamp 3 is in place and the tail plug 5 is assembled with the shell body 1.

[0041] In the above design, the horizontal groove 102 is positioned on both sides of the first protrusion 33 and the second protrusion 53, so that the first protrusion 33 and the second protrusion 53 are fixed in the horizontal groove 102, preventing the wedge clamp 3 and the tail plug 5 from rotating.

[0042] Specifically: such as Figure 1 , Figure 2 and Figure 3As shown, the sealing ring 2 includes an annular ring body 21, a plurality of outer rubber rings 22 arranged axially along the outer side of the annular ring body 21, and an inner rubber ring 23 disposed on the inner side of the annular ring body 21. The outer rubber rings 22 abut against the inner wall of the cavity, and the boss 4 abuts against the annular ring body 21.

[0043] During actual assembly, the outer rubber ring 22 is compressed and deformed against the inner wall of the cavity to fill the gap between the shell body 1 and the annular ring body 21. The wire harness passes through the inner rubber ring 23, causing the inner rubber ring 23 to be compressed and deformed (the aperture of the inner rubber ring 23 is smaller than the diameter of the wire harness). In practical applications, this prevents moisture from passing through the sealing ring 2 from the tail plug 5.

[0044] In the above design, the structural design and specific implementation of the sealing ring 2 can effectively seal one end of the charging gun shell, effectively preventing moisture from entering the electrical module inside the cavity from the tail plug 5 end and damaging it.

[0045] Specifically: such as Figure 2 As shown, the end of the elastic claw 32 is provided with texture 320.

[0046] In actual use, the wire harness is clamped by the end of the elastic claw 32.

[0047] In the above design, by setting texture 320 at the end of the elastic claw 32, the surface roughness of the end of the elastic claw 32 can be increased, the friction force on the wire harness can be increased, and the difficulty of the wire harness separating from the elastic claw 32 can be increased.

[0048] Specifically: such as Figure 4 As shown, the shell body 1 and the boss 4 are integrally formed.

[0049] In the above design, by integrally molding the shell body 1 and the boss 4, the tail plug 5, the wedge clamp 3 and the sealing ring 2 cannot be disassembled after assembly, thus improving the anti-theft capability of the charging gun.

[0050] 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.
