DETAILED DESCRIPTION

[0030] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0031] As shown in Figure 1 and Figure 2 , the charging gun cable fixing device of the embodiment of the present application comprises: a metal fixing assembly 1 and an insulating anti-pulling cable clamp 2, wherein the metal fixing assembly 1 is arranged at the intersection position of the tail part 10 of the gun shell and the cable 20; the insulating anti-pulling cable clamp 2 is used for fixing the cable 20 in cooperation with the metal fixing assembly 1, and the insulating anti-pulling cable clamp 2 comprises an insulating cable clamp body 21 and an elastic arm 22, one end of the elastic arm 22 is connected with the insulating cable clamp body 21, and the elastic arm 22 is provided with an anti-pulling buckle 23 facing the cable 20. Wherein, the insulating anti-pulling cable clamp 2 can be made of insulating materials such as plastic and resin, and the present embodiment is not limited thereto.

[0032] It can be understood that the charging gun cable fixing device of the present application adopts the insulating anti-pulling cable clamp 2 and the metal fixing assembly 1 to fix the cable 20, which can uniformly distribute the force of the clamped cable 20 acting on the inner core on the sheath of the cable 20, meet the cable deflection requirement of the charging gun, and avoid direct contact between the metal fixing assembly 1 and the cable 20, thereby ensuring personal safety; moreover, the elastic arm 22 is arranged on the insulating anti-pulling cable clamp 2, and when the cable 20 is bent or twisted, the elastic arm 22 can play a buffering role between the cable 20 and the metal fixing assembly 1; since the anti-pulling buckle 23 is arranged on the elastic arm 22, when the insulating anti-pulling cable clamp 2 is deformed under the action of the cable 20, the anti-pulling buckle 23 on the elastic arm 22 can still tightly adhere to the cable 20, thereby ensuring the locking effect.

[0033] As shown in Figures 1 to 5 , in an embodiment of the present application, the metal fixing assembly 1 can comprise two metal cable clamps 11 which can be closed, and the metal cable clamp 11 has a first half ring 111, when the two metal cable clamps 11 are closed, the first half rings 111 of the two metal cable clamps 11 are closed to form a convex ring, and the convex ring is in transition fit with the elastic arm 22 of the insulating anti-pulling cable clamp 2.

[0034] When installing the charging gun cable fixing device, the insulating anti-pulling cable clamp 2 needs to be sleeved on the cable 20 first, and then the two metal cable clamps 11 are closed and locked. When the two metal cable clamps 11 are closed but not locked, the convex ring is in point contact with the elastic arm 22 of the insulating anti-pulling cable clamp 2 (as shown in Figure 3 ); after the two metal cable clamps 11 are locked, the convex ring is in surface contact with the elastic arm 22 (as shown inFigure 4 The locking effect is improved.

[0035] In an embodiment of the utility model, the elastic arm 22 is provided with N anti-pulling buckles 23, the metal wire clamp 11 is further provided with a second to N half rings, the minimum inner diameter of the Nth half ring is greater than that of the N-1th half ring, each half ring corresponds to at least one anti-pulling buckle 23, and N is an integer greater than or equal to 2.

[0036] Since each half ring corresponds to one anti-pulling buckle 23, and the minimum inner diameter of the half ring gradually increases from inside to outside, after locking the two metal wire clamps 11, the elastic arm 22 can be in contact with the convex ring surface formed by each half ring, so that the anti-pulling buckle 23 at the corresponding position can obtain strong supporting force, and the locking effect is further improved.

[0037] As shown in the drawings, Figures 1 to 5 In a specific embodiment of the utility model, the elastic arm 22 is provided with two anti-pulling buckles 23, the metal wire clamp 11 is further provided with a second half ring 112, the minimum inner diameter of the second half ring 112 is greater than that of the first half ring 111, and the first half ring 111 and the second half ring 112 correspond to one anti-pulling buckle 23 respectively. In some other embodiments of the utility model, the number and specific structure of the half rings can be set according to specific requirements, the minimum inner diameters of all the half rings on the metal wire clamp 11 can be the same, and the number of the anti-pulling buckles 23 on the elastic arm 22 and the number of the half rings can also be different. The half ring can directly correspond to one anti-pulling buckle 23 in the radial cross section, or can be between two anti-pulling buckles 23, and the embodiment is not limited in this way.

[0038] In a specific embodiment of the utility model, the two metal wire clamps 11 can be fixed by screws 12 (as shown in the drawings), Figure 1 In some other embodiments of the utility model, the two metal wire clamps 11 can also be closed by clamping or bonding, and the embodiment is not limited in this way.

[0039] As shown in the drawings, Figure 1 and 5 In an embodiment of the utility model, the tail part 10 of the gun barrel can be provided with a through hole, and the metal wire clamp 11 can be provided with a protrusion 113 matched with the through hole. When the metal wire clamp 11 is installed, the protrusion 113 can be directly inserted into the through hole to realize positioning of the metal wire clamp 11, and the installation efficiency is improved.

[0040] As shown in the drawings, Figure 6As shown, in one embodiment of this utility model, the insulating wire clip body 21 includes a first insulating ring 211, a second insulating ring 212, and a connector 213. The connector 213 is used to connect the first insulating ring 211 and the second insulating ring 212. One end of the elastic arm 22 is connected to the first insulating ring 211, and there is a gap between the other end of the elastic arm 22 and the second insulating ring 212. The end of the elastic arm 22 near the second insulating ring 212 can move freely within a certain range, so that the insulating tensile wire clip 2 can withstand greater force and is not easily damaged.

[0041] like Figure 6 As shown, in one embodiment of this utility model, the gun shell tail 10 may also be provided with a guide groove, and the second insulating ring 212 may be provided with a guide block 214 adapted to the guide groove. When installing the insulating tensile wire clip 2, the second insulating ring 212 can be inserted into the gun shell tail 10, so that the guide block 214 abuts against the guide groove, thereby achieving the positioning of the insulating tensile wire clip 2 and further improving the installation efficiency.

[0042] In one embodiment of this utility model, the insulating tensile clamp 2 is centrally symmetrical about the central axis of the insulating clamp body 21, so that when the cable 20 is subjected to tensile forces in different directions, the insulating clamp body 21 and the elastic arm 22 can provide opposite support, ensuring the stability of the connection between the charging gun and the cable 20.

[0043] like Figure 3 , 4 As shown in Figure 6, in one embodiment of this utility model, the end of the elastic arm 22 away from the gun housing tail 10 is connected to the insulating cable clamp body 21. The anti-tension buckle 23 has a wedge-shaped structure, with the tip of the anti-tension buckle 23 facing the intersection of the gun housing tail 10 and the cable 20. The wedge-shaped structure of the anti-tension buckle 23 facilitates the smooth movement of the insulating anti-tension cable clamp 2 from the cable 20 to the connection point between the cable 20 and the gun housing tail 10. Moreover, the wedge-shaped structure can generate a self-locking effect when subjected to force, providing greater resistance when the cable 20 is pulled away from the charging gun, thereby improving the stability and safety of the entire structure.

[0044] like Figure 1 As shown, in one embodiment of this utility model, a sealing ring groove is provided in the tail section 10 of the gun shell, and the charging gun cable fixing device also includes a sealing ring 3 that matches the sealing ring groove, so as to play a role in waterproofing and dustproofing.
