[0019] In order to make the purposes, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments will be clearly and completely described with reference to the accompanying drawings in the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all embodiments. Based on the embodiments given, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the scope of the present application.

[0020] In the description of the present application, it should be understood that the terms "upper", "lower" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0021] In the description of the present application, the terms "first", "second" and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated.

[0022] For details Figures 1-4As shown, a bias type wiring harness binding fastener includes a plastic body 10 and a flexible sealing body 12, the plastic body 10 includes a buckle head end 11, the buckle head end 11 has a plurality of deformation zones to enable it to be clamped into and firmly installed into the fixing hole of the automobile metal part. The root of the buckle head end 11 is provided with a pressing portion 111; the sealing body 12 is connected to the pressing portion 111, adjacent to the end face where the buckle head end 11 is located, so that after the buckle head end 11 is clamped into the fixing hole of the automobile metal part, the pressing portion 111 will press the sealing body 12 tightly on the surface around the fixing hole, closing the fixing hole; the pressing portion 111 extends outwardly from the side away from the buckle head end 11 to a connecting portion 13. Among them, the connecting portion 13 extends a binding portion 14 at the end away from the pressing portion 111, thereby realizing the position bias of the binding portion 14 and the fixing hole, then according to the bias size of the fixing hole and the design of the wiring harness, the extension length of the connecting portion 13 is adjusted accordingly, that is, the bias distance of the binding portion 14 to the wiring harness is changed, thereby meeting the use requirements. Specifically, in the present embodiment, the binding portion 14 is wing-shaped, and the middle part is connected to the connecting portion 13. Further, the wing-shaped binding portion 14 is easy to slip out from both ends of the binding portion 14 when the automobile vibrates or jolts after the binding is completed, causing the wiring harness to fall off. Therefore, in the present embodiment, the two ends of the binding portion 14 are preferably provided with protrusions 141 near the corners thereof in the direction perpendicular to the length of the binding portion 14. Thus, the protrusions 141 limit the wiring harness, tape or adhesive tape bound to the binding portion 14, thereby preventing the problem of slipping out, so that the wiring harness can be stably and reliably fixed. Of course, in order to avoid the possibility of scratching the wire by the right angle of the binding portion 14, the corners of the protrusions 141 and the corners 1411 of the binding portion 14 are preferably rounded in the present embodiment.

[0023] In addition, in the present embodiment, the sealing body 12 and the plastic body 10 are integrated. Specifically, the plastic body 10 and the sealing body 12 are integrally injection molded; first, the plastic body 10 is injection molded, and then the plastic body 10 is injection molded again with a flexible material to obtain the sealing body 12, preferably the material of the plastic body 10 is nylon, and the material of the sealing body is preferably TPE. Among them, the sealing body 12 is annular structure and located in the periphery of the buckle head end 11, its outer contour is similar to the outer contour of the pressing portion 111, so that after the buckle head end 11 is clamped into the fixing hole, the sealing body 12 is extruded to the outer surface around the fixing hole by the pressing portion 111, tightly attached to the outer surface around the fixing hole, thereby realizing the closure of the hole of the fixing hole, achieving dustproof and waterproof. Among them, the sealing body 12 can be preferably skirt-shaped, so that the sealing body 12 can have a larger area, so that even if the buckle head end 11 may exist within a certain range in the fixing hole, it can still more reliably close the fixing hole.

[0024] Of course, considering that the binding part 14 will bear a certain load after the bundle is bound, and the binding part 14 and the connecting part 13 will be twisted to a certain extent during the binding process of the worker, which will easily cause the connecting part 13 to break and cause the binding part to fail; Therefore, the connecting part 13 is preferably a wedge-shaped columnar structure in the embodiment. The wedge-shaped columnar structure has the characteristic of typical variable cross-section, which can significantly improve the carrying capacity of the connecting part 13, thereby improving the overall strength of the connecting part 13, and avoiding the easy fracture damage problem when stressed.

[0025] The above embodiment is only a preferred embodiment of the present application, not limited to the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
