Description

Technical Field

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

[0002] With the development of wire harness fixing technology, different devices and methods for fixing wire harnesses have emerged. In the wire harness design process, many wire harness constraint components are designed to protect the wire harness. The wire harness and constraint components are then tied and fixed with cable ties to prevent the constraint components from shaking, thereby preventing the wire harness from being affected by surrounding parts. The fixing components of cable ties and constraint components can effectively fix and protect the wire harness and prevent the wire harness from being scattered during transportation and use.

[0003] In traditional techniques, the constraint components are mostly simple concave structures. The constraint component needs to be placed on the wire harness first, and then the cable ties need to be passed through the cable tie holes on the constraint component for binding and fixing. However, when the wire harness is full of the constraint component, the cable tie holes reserved on the constraint component are often blocked by the wire harness. It is very difficult to insert the cable ties. The process of fixing the wire harness is not only cumbersome but also inefficient. Utility Model Content

[0004] Based on this, this application provides a wire harness fixing component to improve the problem of inconvenient and inefficient cable tie insertion during wire harness fixing.

[0005] A wire harness fixing assembly includes a constraint member and a cable tie. The constraint member has an open receiving groove, and the outer peripheral wall of the receiving groove has a hollow assembly part. The inner wall of the assembly part has a limiting protrusion. The cable tie has a first side and a second side arranged opposite to each other. The first side is close to the outer peripheral wall of the receiving groove, and the second side has a limiting groove that matches the limiting protrusion. When the cable tie passes through the assembly part, the limiting protrusion can be engaged with the limiting groove.

[0006] With this design, the cable tie can pass through the assembly part on the constraint component. The limiting protrusion and the limiting groove can hold the cable tie in place, allowing the cable tie to be pre-installed on the constraint component. When fixing the wire harness, the constraint component and the wire harness can be directly tied and fixed by the pre-installed cable tie, reducing the steps when fixing the wire harness and avoiding the inconvenience caused by the cable tie passing through the hole, thus improving the operation efficiency.

[0007] In one embodiment, the second surface is provided with a first limiting block and a second limiting block at intervals along the length of the cable tie. The first limiting block, the second limiting block and the second surface form an open limiting groove, and the limiting protrusion can be engaged in the limiting groove.

[0008] With this configuration, the second side is provided with a first limiting block and a second limiting block at intervals along the length of the cable tie. When the cable tie is inserted into the assembly part, the limiting protrusion can be engaged in the limiting groove formed by the first limiting block, the second limiting block and the second side of the cable tie, so as to realize the assembly of the cable tie and the constraint component.

[0009] In one embodiment, when the limiting protrusion is engaged in the limiting groove, the highest point of the first limiting block is lower than the highest point of the second limiting block, but higher than the lowest point of the limiting protrusion.

[0010] With this configuration, the highest point of the first limiting block is lower than the highest point of the second limiting block, so that when the cable tie is inserted into the assembly part, it can slide into the limiting groove through the lower first limiting block. The highest point of the first limiting block is higher than the lowest point of the limiting protrusion, so that after the limiting protrusion slides into the limiting groove, it can be locked by the first and second limiting blocks, thereby enabling the cable tie to be locked in the assembly part.

[0011] In one embodiment, the first limiting block has a guide surface on the side opposite to the limiting groove, and the limiting protrusion can slide into the limiting groove through the guide surface.

[0012] With this configuration, the side of the first limiting block opposite to the limiting groove has a guide surface, so that when the cable tie is inserted into the assembly part, the limiting protrusion can slide more smoothly into the limiting groove along the guide surface.

[0013] In one embodiment, the cable tie includes a strip and a cable tie head disposed at one end of the strip, and a first limiting block is disposed on the side away from the cable tie head.

[0014] This design ensures that when the cable tie is inserted into the assembly section, the first limiting block can contact the limiting protrusion first, allowing the limiting protrusion to slide smoothly into the limiting groove through the first limiting block.

[0015] In one embodiment, the guide surface is an inclined surface that extends at an angle toward the highest point of the first limiting block.

[0016] This design creates a smooth guide surface between the first limiting block and the strip, allowing the limiting protrusion to slide smoothly into the limiting groove along the guide surface. It also prevents potential damage to the first limiting block during insertion, thus enhancing the durability of the first limiting block.

[0017] In one embodiment, the limiting groove is centrally located along the length of the cable tie.

[0018] This design allows the cable ties to be positioned evenly on both sides of the assembly section after being secured, reducing the fluctuation of the cable strip and enhancing overall stability. In addition, it can reduce the distance the cable ties need to wrap around the wire harness when binding the wire harness, making the operation more convenient and faster.

[0019] In one embodiment, the first limiting block and the second limiting block are integrally formed with the strip.

[0020] This configuration makes the first limiting block, the second limiting block, and the strap a whole, enhancing the reliability of the first and second limiting blocks, ensuring the fixing effect of the limiting components being locked in the limiting groove, and also facilitating the modular production of cable ties.

[0021] In one embodiment, the assembly is located on the top of the outer wall of the constraint member.

[0022] This design makes it easier to insert cable ties into the assembly section and ensures more balanced force when binding and fixing constraints and wire harnesses.

[0023] In one embodiment, the opening direction of the assembly part is perpendicular to the length direction of the receiving groove.

[0024] This configuration allows the cable ties inserted into the assembly to secure the wire harness and constraints perpendicular to the length of the wire harness. Attached Figure Description

[0038] See Figure 1 , Figure 1 This invention illustrates a wire harness fixing assembly according to an embodiment of the present invention, which is used to fix a wire harness 100. The wire harness fixing assembly includes a constraint member 10 and a cable tie 20. The constraint member 10 has an open receiving groove 11, and the outer peripheral wall of the receiving groove 11 is provided with a hollow assembly part 12. The inner wall of the assembly part 12 is provided with a limiting protrusion 121. The cable tie 20 has a first surface 211 and a second surface 212 arranged opposite to each other. The first surface 211 is close to the outer peripheral wall of the receiving groove 11, and the second surface 212 is provided with a limiting groove 213 that matches the limiting protrusion 121. When the cable tie 20 passes through the assembly part 12, the limiting protrusion 121 can be engaged with the limiting groove 213.

[0039] For details, please refer to Figures 1-5 As shown, the constraint member 10 has an open receiving groove 11. The receiving groove 11 is U-shaped and has a partition in the middle, which can accommodate two sets of wire harnesses 100 at the same time. The outer peripheral wall of the receiving groove 11 has a hollow assembly part 12, which allows the cable tie 20 to be inserted into the assembly part 12. The inner wall of the assembly part 12 has a limiting protrusion 121. The cable tie 20 has a limiting groove 213 that matches the limiting protrusion 121. When the cable tie 20 is inserted into the assembly part 12, the limiting protrusion 121 can be locked in the limiting groove 213. This allows the cable tie 20 to be pre-installed on the constraint member 10. When fixing the wire harness 100, the constraint member 10 and the wire harness 100 can be directly tied and fixed by the pre-installed cable tie 20, which reduces the steps when fixing the wire harness 100 and avoids the inconvenience caused by the cable tie 20 passing through the hole, thus improving the operation efficiency.

[0040] Similarly, in other embodiments, the receiving groove 11 can be in the shape of a W, a 7, or other forms. The receiving groove 11 may not have a partition in the middle. As long as the outer peripheral wall of the receiving groove 11 has a hollow assembly part 12, the cable tie 20 can be pre-installed into the assembly part 12. The specific arrangement can refer to the arrangement of the receiving groove 11 and the assembly part 12 described above, and will not be elaborated further.

[0041] In this embodiment, the second surface 212 is provided with a first limiting block 214 and a second limiting block 215 at intervals along the length direction of the cable tie 20. The first limiting block 214, the second limiting block 215 and the second surface 212 form an open limiting groove 213, and the limiting protrusion 121 can be locked in the limiting groove 213.

[0042] For details, please refer to Figure 5 As shown, the first limiting block 214 and the second limiting block 215 are spaced apart along the length of the cable tie 20, and together with the second surface 212 on the cable tie 20, they form an open limiting groove 213, so that the limiting protrusion 121 in the assembly part 12 can be engaged in the limiting groove 213, thereby enabling the cable tie 20 to be pre-installed on the constraint member 10, and the assembly method is simple and reliable.

[0043] See Figure 3 As shown, in order for the cable tie 20 to be snapped into the assembly part 12, in this embodiment, when the limiting protrusion 121 is snapped into the limiting groove 213, the highest point of the first limiting block 214 is lower than the highest point of the second limiting block 215, but higher than the lowest point of the limiting protrusion 121. Therefore, along the orthographic projection perpendicular to the extending direction of the limiting protrusion 121, the first limiting block and the limiting protrusion 121, and the second limiting block 215 and the limiting protrusion 121, all partially overlap, so that when the limiting protrusion 121 is located in the limiting groove 213, the cable tie 20 can be restricted in the assembly part 12.

[0044] See Figure 2 and Figure 3 As shown, in order to allow the limiting protrusion 121 to slide smoothly into the limiting groove 213, in this embodiment, the first limiting block 214 has a guide surface 2141 on the side opposite to the limiting groove 213. The limiting protrusion 121 can slide into the limiting groove 213 through the guide surface 2141. This allows the limiting protrusion 121 to slide more smoothly into the limiting groove 213 along the guide surface 2141 when the cable tie 20 is inserted into the assembly part 12, making the locking operation simpler and smoother.

[0045] In this embodiment, the cable tie 20 includes a strip 21 and a cable tie head 22 disposed at one end of the strip 21, and the first limiting block 214 is disposed on the side away from the cable tie head 22.

[0046] For details, please refer to Figure 1 Figure 5 As shown, the cable tie 20 is inserted into the assembly part 12 from the side away from the cable tie head 22. The first limiting block 214 is located on the side away from the cable tie head 22, so that the first limiting block 214 can contact the limiting protrusion 121 first, thereby ensuring that the limiting protrusion 121 slides smoothly into the limiting groove 213 through the first limiting block 214.

[0047] See Figure 2 , Figure 3 and Figure 5 As shown, to further ensure that the limiting protrusion 121 can smoothly slide into the limiting groove 213 and enhance the durability of the first limiting block 214, in this embodiment, the guide surface 2141 is an inclined surface extending from the strip 21 towards the highest point of the first limiting block 214. The guide surface 2141 connects the first limiting block 214 and the strip 21 into a whole, so that there is a smooth guide surface 2141 between the first limiting block 214 and the strip 21, thereby allowing the limiting protrusion 121 to smoothly slide into the limiting groove 213 and increasing the durability of the first limiting block 214.

[0048] See Figure 1 and Figure 5 As shown, in this embodiment, the limiting groove 213 is centrally arranged along the length of the cable tie 20. This allows the cable tie 20 to be secured in the assembly part 12, balancing the force on both sides of the cable tie 20, reducing the fluctuation of the strip 21, and enhancing overall stability. In addition, it can reduce the distance the cable tie 20 wraps around the wire harness 100 when binding the wire harness 100, making the operation more convenient and faster.

[0049] See Figure 5 As shown, to enhance the reliability of the limiting groove 213 structure, in this embodiment, the first limiting block 214 and the second limiting block 215 are both integrally formed with the strap 21. This enhances the overall integrity of the cable tie 20 structure, ensures the fixing effect of the limiting component in the limiting groove 213, and also facilitates the modular production of the cable tie 20.

[0050] See Figure 1 and Figure 4 As shown, in this embodiment, the assembly part 12 is located on the top of the outer wall of the constraint member 10. This makes it easier to insert the cable tie 20 into the assembly part 12, and the force is more balanced when binding and fixing the constraint member 10 and the wire harness 100.

[0051] See Figure 1 and Figure 4As shown, in order to ensure the fixing effect of the cable tie 20 on the constraint member 10 and the wire harness 100, in this embodiment, the opening direction of the assembly part 12 is perpendicular to the length direction of the receiving groove 11. This makes the cable tie 20 inserted into the assembly part 12 perpendicular to the length direction of the receiving groove 11, that is, perpendicular to the length direction of the wire harness 100 placed in the receiving groove 11, thereby enabling the wire harness 100 and the constraint member 10 to be bound and fixed to the greatest extent.

[0052] 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.

[0053] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
