[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] In the claims, specification and the above-mentioned drawings of the utility model, unless otherwise clearly defined, the use of terms such as "first", "second" or "third" etc. is to distinguish different objects rather than to describe a specific order.

[0032] Please also read Figures 1 to 8 , the fixing structure of the wiring harness connector provided by the utility model is now described. The fixing structure of the wiring harness connector includes a connector body 2 and a plug connector 1; the plug connector 1 is fixed on the connector body 2; the connector body 2 is fixed to the vehicle body through the plug connector 1; the plug connector 1 has a plug board body 11 and a limit plug board 12 arranged on the plug board body 11, the plug board body 11 is fixed on the connector body 2, the limit plug board 12 is located on the side of the plug board body 11 facing away from the connector body 2, and the limit plug board 12 is inserted along the first direction to constitute the second direction limit of the connector body 2; the plug board body 11 has an extension portion 14 extending beyond the limit plug board 12 along the first direction, and the extension portion 14 is provided with a first limit groove 142 perpendicular to the first direction, and the first limit groove 142 constitutes the first direction limit of the connector body 2; wherein the corresponding slot or socket arranged on the vehicle body constitutes the third direction limit of the connector body 2; the first direction, the second direction and the third direction are perpendicular to each other.

[0033] The fixing structure of the wiring harness connector provided by the utility model has the beneficial effect of constructing a fixing method of plug-in connection of a plug-in plate different from that of a claw, utilizing the limiting plug-in plate 12 as a second direction limit, utilizing the first limiting groove 142 of the extension portion 14 as a first direction limit, and at the same time, the matching socket can be used as a third direction limit, so that the wiring harness connector can be fixed to the vehicle body through the plug-in component 1, and the three-dimensional direction limit is realized, thereby ensuring the firmness of the wiring harness connector; and this plug-in method, which adopts the plug-in method of the plug-in plate, is not easy to damage itself or the socket during the process of disassembly and pulling, is easy to disassemble, and has high reliability for repeated use, can avoid the existing wiring harness connector being loosened, resulting in circuit faults such as wiring harness friction, interference, and insulation damage, thereby improving driving safety.

[0034] The first direction, the second direction and the third direction used in the present application are determined according to the movement direction and the limit direction of the connector 1 itself. Since the plug-in position of the connector 1 on the vehicle body can be arranged at any angle or any position according to the design of the wiring harness layout, its direction is not necessarily consistent with the up-down direction, the front-back direction and the left-right direction of the vehicle body.

[0035] It should be noted that the installation of the present application necessarily requires a matching socket or slot to be provided on the vehicle body, and a second limiting groove 15 is provided in the socket to be slidably matched with the limiting plug plate 12, and the second limiting groove 15 also extends along the first direction; a limiting protrusion matching the first limiting groove 142 is also required to be provided in the socket to limit the plug connector 1, so the design of the socket needs to be adapted to the structure of the plug connector 1. Since the extension 14 is a suspension end, it has a tendency to deform under force. When the plug connector 1 is plugged, the extension 14 is first inserted into the socket and contacts the inner wall of the socket. When the suspension end of the extension 14 first contacts the limiting protrusion and is lifted up by the limiting protrusion to elastically deform, when the first limiting groove 142 encounters the limiting protrusion in the socket, the extension 14 is reset, the thrust is blocked, and it can stop. At this time, the limiting plug plate 12 is inserted into the second limiting groove 15.

[0036] When disassembling, the connector 1 is pulled out with a little force, and the pulling force is decomposed into an outward thrust at the position of the limiting protrusion, so that the first limiting groove 142 is disengaged from the limiting protrusion, thereby realizing the disassembly of the connector 1.

[0037] In some embodiments, see Figures 5 to 8 The two opposite groove walls of the first limiting groove 142 are both first guiding inclined surfaces for facilitating the insertion or removal of the plug-in connector 1. The first limiting groove 142 is in a V-shaped structure. The two guiding inclined surfaces of the first limiting groove 142 not only facilitate the plug-in connector 1 to overcome the limiting protrusion and be installed in place, but also facilitate the plug-in connector 1 to cross the limiting protrusion and be removed.

[0038] In some embodiments, see Figures 5 to 8The end of the extension part 14 away from the limiting plug plate 12 is provided with a second guiding inclined surface 141. The second guiding inclined surface 141 has a guiding function corresponding to the plugging of the extension part 14, so as to facilitate the installation of the plug connector 1.

[0039] In some embodiments, see Figures 5 to 8 The plugboard body 11 is provided with a first limiting step 111 for limiting the insertion depth of the plug connector 1, and the first limiting step 111 and the second guiding inclined surface 141 are located on opposite sides of the first limiting groove 142. The first limiting step 111 on the plugboard body 11 has a locking and limiting effect on the insertion depth of the plug connector 1, so as to prevent the first limiting groove 142 from crossing over the limiting protrusion if too much force is applied after the first limiting groove 142 and the limiting protrusion are matched, and thus fail to play a fixing role.

[0040] In some embodiments, see Figures 5 to 8 The extension portion 14 is also provided with a weight-reducing hole 143 to reduce the deadweight of the connector 1 and avoid burdening the weight of the entire vehicle.

[0041] In some embodiments, see Figures 5 to 8 , the second limiting grooves 15 are formed between the two opposite sides of the limiting plug plate 12 and the plug plate body 11. Specifically, the second limiting grooves 15 are formed on both sides of the limiting plug plate 12, so that a structure similar to a dovetail groove is formed between the limiting plug plate 12 and the plug plate body 11, which has a good limiting effect and also forms a third direction limit for the plug connector 1.

[0042] In some embodiments, see Figures 5 to 8 A weight-reducing groove 121 is provided on the plugboard body 11, and its function is to reduce the dead weight of the plug connector 1 to avoid affecting the weight of the entire vehicle.

[0043] In some embodiments, see Figures 5 to 8 A second limiting step 13 is provided at one end of the plug board body 11 away from the extension portion 14. The second limiting step 13 constitutes the last line of defense of the plug connector 1 along the first direction, ensuring that the plug-in position of the plug connector 1 will not be affected by a large thrust, thereby ensuring the consistency between the installation position of the wiring harness connector and the designed position, and ensuring the smoothness of the wiring harness routing.

[0044] In some embodiments, see Figures 5 to 8 The connector body 2 is provided with a plurality of mounting planes 22 for fixing the plug connector 1. The plug connector 1 and the connector body 2 are made separately, and the plug connector 1 can be selectively fixed on the mounting plane 22 according to the direction and installation position of the wiring harness, thereby improving the flexibility and versatility of the connector fixation.
