Description

Technical Field

[0001] This utility model belongs to the technical field of wire harness fixing, and in particular relates to a wire harness fixing component. Background Technology

[0002] New energy vehicles typically require a large number of wiring harnesses to connect electrical components. To avoid tangled wiring, clips are commonly used to secure the harnesses to the vehicle's sheet metal. However, existing clips have reliability issues; after securing the harnesses to the sheet metal, they can wobble due to vibrations during vehicle operation, potentially causing the harnesses to detach. Utility Model Content

[0003] In view of this, it is necessary to provide a wire harness fixing component for solving the above-mentioned technical problems.

[0004] A wire harness fixing assembly, the wire harness fixing assembly comprising:

[0005] A fixed tube is formed to enclose a limiting cavity, through which a wire harness can pass. The outer wall of the fixed tube is provided with a slot body and a limiting protrusion, with the limiting protrusion located in the extending direction of the slot body.

[0006] A fixing clip includes a connecting plate that can be inserted into a slot. A snap-fit ​​connector is provided on the connecting plate at the position of the slot, which is used to snap into the body sheet metal. A hook portion is formed on one end of the connecting plate that passes through the slot. The hook portion can pass through the limiting protrusion and abut against the limiting protrusion for limitation. Furthermore, the hook portion that abuts against the limiting protrusion is interference-fitted with the fixing tube.

[0007] It is understandable that the wiring harness is supported by the limiting cavity of the fixing tube, and the fixing clips are used to fix the wiring harness to the body sheet metal. In this process, the fixing clips are installed to the fixing tube by plugging in, and the interference fit between the two ensures the connection stability. This can effectively suppress the loosening between the fixing tube and the fixing clips caused by vehicle vibration, and prevent the wiring harness fixed by the wiring harness fixing component from coming loose.

[0008] In one embodiment, in the direction perpendicular to the insertion direction when the connecting plate is inserted into the slot body, the hook portion forms a positional interference with the outer wall of the fixing tube, and the hook portion is press-fitted with the fixing tube.

[0009] In one embodiment, the connecting plate has a plug-in portion, and the connecting plate can be plugged into the slot body through the plug-in portion;

[0010] The end face of the plug portion facing the fixing tube is configured as an arc-shaped convex surface.

[0011] It is understandable that the arc-shaped convex surface on the connecting plate can prevent gaps when the connecting plate is inserted into the slot, thus facilitating the insertion of the connecting plate into the slot and making it easier to assemble the fixing clips on the fixing tube.

[0012] In one embodiment, one end face of the limiting protrusion facing the slot body is configured as a guide slope;

[0013] When the connecting plate is inserted into the slot, the hook portion can pass through the limiting protrusion under the guidance of the guide slope and then abut against the limiting protrusion for a limiting position.

[0014] It is understandable that the guide ramp on the limiting protrusion is used to guide the hook part through the limiting protrusion, so that the hook part can pass through the limiting protrusion under the action of the connecting plate.

[0015] In one embodiment, the hook portion has a locking surface, and the hook portion can be locked by abutting the limiting protrusion through the locking surface;

[0016] The connecting plate has a limiting groove, the groove wall of which includes a wall surface, and the wall surface and the locking surface are disposed on the same plane; and the limiting protrusion is partially inserted into the limiting groove and abuts against the wall surface for limiting.

[0017] In one embodiment, the slot body and the limiting protrusion are combined to form a connecting assembly, and the fixing pin can be installed on the fixing tube through the connecting assembly;

[0018] The number of connecting components is configured as two groups, and the two groups of connecting components are symmetrically arranged on the fixed tube.

[0019] Understandably, the fixing clips can be flexibly installed on one side of the fixing tube, allowing the wiring harness fixing assembly to adapt to the installation requirements of different body sheet metals, thus improving the versatility and assembly adaptability of the wiring harness fixing assembly.

[0020] In one embodiment, the fixing tube includes a first tube section and a second tube section, the first tube section and the second tube section being connected and communicating with each other;

[0021] The slot body is disposed on the connection between the first tube and the second tube, and the limiting protrusion is disposed on the first tube or the second tube.

[0022] In one embodiment, the fixing tube includes a first half-tube and a second half-tube, wherein the first half-tube is connected to the second half-tube in a snap-fit ​​manner.

[0023] The limiting cavity is formed between the first half-tube and the second half-tube.

[0024] It is understandable that the first half of the tube and the second half of the tube are snapped together to form a fixed tube, which facilitates the assembly of the wire harness on the fixed tube.

[0025] In one embodiment, the fixing pin forms a limiting protrusion at the position where the connecting plate body and the clip head are connected, and the outer diameter of the limiting protrusion gradually decreases in the direction towards the connecting plate body;

[0026] When the snap-fit ​​connector engages with the body sheet metal, the limiting protrusion can be squeezed and deformed against the body sheet metal.

[0027] Understandably, the stability of the fixing clip can be improved by using the extrusion deformation of the limiting protrusion on the body sheet metal.

[0028] In one embodiment, both the fixing tube and the fixing clip are configured as injection molded parts.

[0029] It is understandable that the fixing tube and fixing clips can be manufactured by injection molding, which facilitates the production and manufacturing of the fixing tube and fixing clips.

[0030] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0031] The wiring harness fixing assembly claimed in this application uses the limiting cavity of the fixing tube to carry the wiring harness, and uses the fixing clips to engage with the body sheet metal to fix the wiring harness to the body sheet metal. In this process, the fixing clips are installed into the fixing tube by plugging in, and the interference fit between the two ensures the connection stability. This can effectively suppress the loosening between the fixing tube and the fixing clips caused by vehicle vibration, and prevent the wiring harness fixed by the wiring harness fixing assembly from coming loose.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0041] The wiring harness fixing assembly 100 claimed in this application is used to fix a wiring harness (not shown) to a vehicle body sheet metal (not shown) to achieve the fixation of the wiring harness on the vehicle body sheet metal. Here, the vehicle body sheet metal can specifically refer to the sheet metal in a new energy vehicle.

[0042] like Figures 1 to 4 As shown, the wire harness fixing assembly 100 claimed in this application includes a fixing tube 10 and a fixing pin 20. The fixing tube 10 encloses a limiting cavity 101 through which the wire harness can pass. The outer wall 102 of the fixing tube 10 is provided with a slot body 11 and a limiting protrusion 12, which is located in the extending direction of the slot body 11. The fixing pin 20 includes a connecting plate 21 that can be inserted into the slot body 11. A snap-fit ​​connector 22 is provided on the connecting plate 21 at the position of the slot body 11 for snap-fitting with the body sheet metal. A hook portion 23 is formed on one end of the connecting plate 21 that passes through the slot body 11. The hook portion 23 can pass through the limiting protrusion 12 and abut against the limiting protrusion 12 for limiting. The hook portion 23 that abuts against the limiting protrusion 12 is interference-fitted with the fixing tube 10.

[0043] As can be seen from the above, the wiring harness fixing assembly 100 of this application uses the limiting cavity 101 of the fixing tube 10 to carry the wiring harness, and uses the fixing clip 20 to engage with the body sheet metal to fix the wiring harness on the body sheet metal. In this process, the fixing clip 20 is installed to the fixing tube 10 by plugging in, and the interference fit between the two ensures the connection stability. This can effectively suppress the loosening between the fixing tube 10 and the fixing clip 20 caused by vehicle vibration, and prevent the wiring harness fixed by the wiring harness fixing assembly 100 from coming loose.

[0044] It should be noted that the hook portion 23 on the fixing pin 20 of this application forms a positional interference with the outer tube wall 102 of the fixing tube 10 in the vertical direction of the insertion direction when the connecting plate body 21 is inserted into the slot body 11, thereby achieving an interference fit between the hook portion 23 and the fixing tube 10.

[0045] like Figure 1 , Figure 2 As shown, in one embodiment, the slot body 11 and the limiting protrusion 12 combine to form a connecting assembly (not shown), and the fixing pin 20 can be installed on the fixing tube 10 through the connecting assembly; wherein, the number of connecting assemblies is configured as two sets, and the two sets of connecting assemblies are symmetrically arranged on the fixing tube 10. That is to say, the fixing pin 20 in this embodiment can be flexibly selected to be assembled on one side of the fixing tube 10, so that the wiring harness fixing assembly 100 can adapt to the installation requirements of different body sheet metals, thereby improving the versatility and assembly adaptability of the wiring harness fixing assembly 100.

[0046] like Figure 1 , Figure 2 As shown, in one embodiment, the fixing tube 10 includes a first tube portion 110 and a second tube portion 120, which are connected and communicate with each other. A slot body 11 is disposed on the connection between the first tube portion 110 and the second tube portion 120, and a limiting protrusion 12 is disposed on either the first tube portion 110 or the second tube portion 120. Here, the center line of the first tube portion 110 is perpendicular to the center line of the second tube portion 120, enabling the fixing tube 10 to guide the wire harness to make a right-angle turn. It is understood that in other embodiments, the angle formed between the center line of the first tube portion 110 and the center line of the second tube portion 120 can also be 70°, 80°, 110°, etc., which will not be elaborated here.

[0047] like Figure 1 , Figure 2 As shown, in this embodiment, the fixing tube 10 includes a first half-tube 1100 and a second half-tube 1200. The first half-tube 1100 is connected to the second half-tube 1200 by a snap-fit ​​connection. Furthermore, a limiting cavity 101 is formed between the first half-tube 1100 and the second half-tube 1200. That is, the fixing tube 10 in this embodiment can be assembled by the snap-fit ​​connection between the first half-tube 1100 and the second half-tube 1200, which facilitates the assembly of the wire harness on the fixing tube 10.

[0048] like Figure 1 , Figure 3 and Figure 4 As shown, in one embodiment, the connecting plate 21 has a plug-in portion 211, and the connecting plate 21 can be plugged into the slot body 11 through the plug-in portion 211; wherein, the end face of the plug-in portion 211 facing the fixing tube 10 is configured as an arc-shaped convex surface 2111. This allows the arc-shaped convex surface 2111 on the connecting plate 21 to provide clearance for the slot body 11 during the insertion of the connecting plate 21 into the slot body 11, thus facilitating the insertion of the connecting plate 21 into the slot body 11 and thereby facilitating the assembly of the fixing pin 20 on the fixing tube 10.

[0049] like Figures 2 to 4 As shown, in one embodiment, the end face of the limiting protrusion 12 facing the slot body 11 is configured as a guide slope 121. When the connecting plate body 21 is inserted into the slot body 11, the hook part 23 can pass through the limiting protrusion 12 under the guidance of the guide slope 121 and abut against the limiting protrusion 12 for limitation. This allows the hook part 23 to deform outward under the action of the guide slope 121, which satisfies the usage requirement of the hook part 23 passing through the limiting protrusion 12 and facilitates the hook part 23 passing through the limiting protrusion 12 under the action of the connecting plate body 21.

[0050] like Figures 2 to 4As shown, in this embodiment, the hook portion 23 has a locking surface 231, and the hook portion 23 can be locked by abutting the limiting protrusion 12 through the locking surface 231; wherein, a limiting through groove 212 is provided on the connecting plate 21, and the groove wall of the limiting through groove 212 includes a wall surface 2121, the wall surface 2121 and the locking surface 231 are disposed on the same plane; and, the limiting protrusion 12 is partially inserted into the limiting through groove 212 and abuts the wall surface 2121 for locking, thus satisfying the assembly requirement that the hook portion 23 passes through the limiting protrusion 12 and abuts the limiting protrusion 12 for locking.

[0051] like Figure 2 As shown, in one embodiment, the fixing pin 20 forms a limiting protrusion 24 at the position where the connecting plate 21 connects to the snap-fit ​​connector 22. The outer diameter of the limiting protrusion 24 gradually decreases in the direction towards the connecting plate 21. When the snap-fit ​​connector 22 engages with the body sheet metal, the limiting protrusion 24 can be deformed by compression against the body sheet metal. That is, when the fixing pin 20 engages with the body sheet metal through the snap-fit ​​connector 22, the limiting protrusion 24 of the fixing pin 20 is deformed under pressure, which can improve the stability of the fixing pin 20 on the body sheet metal.

[0052] Furthermore, it should be noted that both the fixing tube 10 and the fixing clip 20 in this application are configured as injection molded parts, enabling the fixing tube 10 and the fixing clip 20 to be manufactured by injection molding, which facilitates the production and manufacturing of the fixing tube 10 and the fixing clip 20. Here, the first half-tube 1100 and the second half-tube 1200 of the assembled fixing tube 10 can be manufactured by injection molding respectively.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
