Description
Technical Field
[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a wiring harness fixing bracket for vehicles. Background Technology
[0002] Existing automotive wiring harness mounting brackets are all directly injection molded. However, for automotive wiring harnesses of different applications, due to the varying quantity and specifications of the wiring harnesses, different injection molds must be selected based on the quantity and specifications of the wiring harnesses when injection molding the mounting brackets. This significantly increases the design and mold-making costs of the injection molds for automotive wiring harness mounting brackets, thereby greatly increasing the production cost of automotive wiring harness mounting brackets. Utility Model Content
[0003] To reduce the production cost of automotive wiring harness mounting brackets, this utility model proposes an automotive wiring harness mounting bracket comprising a base and a wiring pad. The base has a wiring through groove in its center, and a pad groove for mounting the wiring pad is located in the center of the wiring through groove. The wiring pad is mounted in the pad groove, and the wiring pad has wiring holes. Thus, in the production of this automotive wiring harness mounting bracket, only the base needs to be injection molded, and then the wiring pad can be installed into the pad groove. Therefore, when producing the automotive wiring harness fixing base of this utility model, it is only necessary to first use an injection mold of the same structure and specifications to form a base, and then select the corresponding wiring pads according to the quantity and specifications of the automotive wiring harness and install them into the pad slots in the base. There is no need to develop and manufacture injection molds of various structures and specifications according to the quantity and specifications of the automotive wiring harness, which effectively saves the design and mold opening costs of the injection mold for the automotive wiring harness fixing base, thereby effectively reducing the production cost of the automotive wiring harness fixing base of this utility model.
[0004] Preferably, the wire harness through-hole is located near the edge of the through-hole pad, and the edge of the through-hole pad has a locking slot communicating with the wire harness through-hole. This locking slot at the edge of the through-hole pad facilitates the installation of the automotive wire harness into the through-hole by the assembly personnel, improving the assembly efficiency of the automotive wire harness. Furthermore, the sidewalls on both sides of the locking slot are V-shaped. This prevents the glue from flowing out from the locking slot during the glue-applying operation after the automotive wire harness and through-hole pad are assembled into the base, thus avoiding affecting the glue-applying effect.
[0005] Preferably, the edge of the threading washer is provided with a raised ridge. This raised ridge at the edge of the threading washer facilitates an interference fit between the threading washer and the side wall of the washer groove when the threading washer is installed into the washer groove, improving the installation stability of the threading washer in the washer groove and preventing the threading washer from falling out of the washer groove, thus affecting the production efficiency and yield of the automotive wiring harness threading fixing seat of this utility model. Further, the cross-section of the raised ridge is a V-shaped structure. This allows the V-shaped tip of the raised ridge to interfere with the inner wall of the washer groove when the threading washer is installed into the washer groove, further improving the installation stability of the threading washer in the washer groove.
[0006] Preferably, a connecting buckle is provided on the outer wall of the connecting end of the base, and a buckle groove is provided on the snap-fit surface of the connecting buckle. This allows the connecting buckle on the outer wall of the connecting end of the base to snap into the corresponding accessory, and the buckle groove on the snap-fit surface of the connecting buckle can be used to snap and limit the connection with the accessory, preventing the connecting end from detaching due to excessive rotation when the base rotates, thus affecting assembly efficiency. Furthermore, a through-glue groove is provided between the inner and outer walls of the connecting end of the base, and this through-glue groove is symmetrically arranged on both sides of the threaded through groove. This through-glue groove between the inner and outer walls of the connecting end of the base can prevent through-glue problems during injection molding of the base, and can also prevent uneven wall thickness of the side walls of the injection-molded base, or even shrinkage problems, which would affect the yield of the injection-molded base.
[0007] Preferably, a sealing ring is fitted onto the connecting end of the base, and the sealing surface of the sealing ring has a wavy structure. This improves the sealing performance when the automotive wiring harness mounting bracket connects to the fitting, by fitting a sealing ring onto the connecting end of the base and having a wavy sealing surface. Furthermore, an annular groove for installing the sealing ring is provided on the outer wall of the connecting end of the base. This ensures that when the sealing ring is fitted onto the connecting end of the base, it is secured in the annular groove, preventing it from detaching and improving the installation stability of the sealing ring on the base.
[0008] Preferably, the mounting end of the base is provided with a handle, and the handle is symmetrically arranged on both sides of the wire-passing groove. Thus, when assembling the automotive wiring harness fixing seat of this invention with the corresponding accessories, the assembler only needs to hold the handle to screw the automotive wiring harness fixing seat together, making assembly simple and convenient.

[0014] Below, in conjunction with Figures 1 to 5 This invention provides a detailed description of the automotive wiring harness fixing bracket.
[0015] like Figures 1 to 3As shown, the automotive wiring harness fixing base of this utility model includes a base 1 and a wiring pad 2. The base 1 has a wiring through groove 101 in its center, and a pad groove 102 for mounting the wiring pad 2 is provided in the center of the wiring through groove 101. The wiring pad 2 is mounted in the pad groove 102, and the wiring pad 2 has a wiring harness through hole 21. Therefore, in the production of this automotive wiring harness fixing base, it is only necessary to use an injection mold to form the base 1, and then install the wiring pad 2 into the pad groove 102. Therefore, in producing the automotive wiring harness fixing bracket of this utility model, it is only necessary to first use an injection mold of the same structure and specifications to form the base 1, and then select the corresponding threading pad 2 according to the quantity and specifications of the automotive wiring harness (not shown in the figure) and install it into the pad groove 102 in the base 1. This eliminates the need to develop and manufacture injection molds of various structures and specifications based on the quantity and specifications of the automotive wiring harness, effectively saving the design and mold-making costs of the injection mold for the automotive wiring harness fixing bracket, thereby effectively reducing the production cost of the automotive wiring harness fixing bracket of this utility model. Preferably, a connecting buckle 111 is provided on the outer wall of the connecting end 11 of the base 1, and a buckle groove 1111 is provided on the snapping surface of the connecting buckle 111. Thus, a connecting buckle 111 is provided on the outer wall of the connecting end 11 of the base 1 for buckling connection with the corresponding accessory (not shown in the figure), and a buckle groove 1111 is provided on the snap-fit surface of the connecting buckle 111. The buckle groove 1111 can be used to buckle and limit the connection with the corresponding accessory, preventing the connecting end 11 from falling off due to excessive rotation when the base 1 rotates and is connected to the corresponding accessory through the connecting buckle 111, thus affecting assembly efficiency. Preferably, a glue-through groove 112 is provided between the inner wall and the outer wall of the connecting end 11 of the base 1, and the glue-through groove 112 is symmetrically arranged on both sides of the wire-through groove 101. In this way, the glue-through groove 112 between the inner wall and the outer wall of the connecting end 11 of the base 1 can not only avoid glue leakage problems during injection molding of the base 1, but also prevent uneven wall thickness of the side wall of the connecting end 11 of the injection-molded base 1, or even shrinkage problems, which would affect the yield of the injection-molded base 1. Preferably, a sealing ring 3 is fitted onto the connecting end 11 of the base 1, and the sealing surface 31 of the sealing ring 3 has a wavy structure. This improves the sealing performance of the automotive wiring harness mounting bracket when connected to the fitting by fitting the sealing ring 3 onto the connecting end 11 of the base 1 and setting the sealing surface 31 of the sealing ring 3 to a wavy structure. Preferably, an annular groove 113 for installing the sealing ring 3 is provided on the outer wall of the connecting end 11 of the base 1. This ensures that when the sealing ring 3 is fitted onto the connecting end 11 of the base 1, it is secured in the annular groove 113, preventing the sealing ring 3 from falling off the connecting end 11 of the base 1 and improving the installation stability of the sealing ring 3 on the base 1. Preferably, a handle 121 is provided on the mounting end 12 of the base 1, and the handle 121 is symmetrically arranged on both sides of the wiring through groove 101.Thus, when assembling the automotive wiring harness fixing seat of this utility model with the corresponding accessories, the assembler only needs to use the handle 121 to screw the automotive wiring harness fixing seat of this utility model together with the corresponding accessories, making the assembly simple and convenient.
[0016] like Figure 2 , 4 As shown in Figure 5, on the wire harness threading pad 2, the wire harness threading hole 21 is located near the edge of the wire harness threading pad 1, and a retaining slot 22 communicating with the wire harness threading hole 21 is provided at the edge of the wire harness threading pad 1. This retaining slot 22 at the edge of the wire harness threading pad 2, communicating with the wire harness threading hole 21, facilitates the assembly personnel in installing the automotive wire harness into the wire harness threading hole 21, improving the assembly efficiency of the automotive wire harness. Preferably, the side walls 221 on both sides of the retaining slot 22 are V-shaped. This prevents the glue from flowing out from the retaining slot 22 during the glue-filling operation after the automotive wire harness and wire harness threading pad 2 are assembled into the base 1, thus avoiding affecting the glue-filling effect. Preferably, the edge of the wire harness threading pad 2 is provided with a raised ridge 23. Thus, a protruding ridge 23 is provided at the edge of the wire harness pad 2 to facilitate an interference fit between the wire harness pad 2 and the side wall of the pad groove 102 when the wire harness pad 2 is installed into the pad groove 102. This improves the installation stability of the wire harness pad 2 in the pad groove 102 and prevents the wire harness pad 2 from falling out of the pad groove 101, which would affect the production efficiency and yield of the automotive wiring harness fixing seat of this utility model. Preferably, the cross-section of the protruding ridge 23 is a V-shaped structure. In this way, when the wire harness pad 2 is installed into the pad groove 102, the V-shaped tip of the protruding ridge 23 can be used to make an interference fit with the inner wall of the pad groove 102, which can further improve the installation stability of the wire harness pad 2 in the pad groove 102. Preferably, the number and position of the wire harness holes 21 on the wire harness pad 2 can be set according to actual needs.
