Description

Technical Field

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

[0002] In automotive high-voltage wiring harness design, cable ties are typically used to secure the harness and prevent it from shifting or moving during operation, thus avoiding friction or collision with surrounding parts. However, the securing effect of cable ties is limited. During harness movement, the cable ties may deform under stress, leading to detachment or breakage, resulting in harness fixation failure. In such cases, the harness may interfere with surrounding parts, causing wear and affecting overall vehicle safety. Furthermore, because the heights of the cables within the cable-tied harness vary, a height difference exists between the cable insertion point and the cable tie fixing point. This height difference can cause stress at the insertion point, deforming the cable seal and increasing the risk of water ingress into the insertion point.

[0003] Therefore, there is a need to provide a wire harness fixing device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a wire harness fixing device that improves the reliability and stability of wire harness fixing and enables all cables in the wire harness to be at the same height, thus avoiding the risk of water entering the plug due to height differences between the cables.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A wire harness fixing device, comprising:

[0007] The main body is made of an elastic material. Multiple accommodating cavities are formed through the main body and distributed along the X-axis. The main body has multiple notches that are connected to the accommodating cavities. The width of the notches is smaller than the diameter of the cable, and the cable can be squeezed into the accommodating cavity through the notches.

[0008] Preferably, the wire harness fixing device further includes:

[0009] The limiting component includes two limiting members, which are spaced apart along the Y-axis on the outer wall of the main body. The mounting member can be engaged between the two limiting members so that the wire harness fixing device is limited and positioned on the mounting member.

[0010] Preferably, the limiting member extends along the outer peripheral surface of the body.

[0011] Preferably, the number of limiting components is multiple sets, and the multiple sets of limiting components are arranged at intervals around the outer peripheral surface of the main body.

[0012] Preferably, the limiting component is integrally formed with the main body.

[0013] Preferably, the outer periphery of the main body is provided with a fixing groove, and the mounting component can be disposed in the fixing groove so that the wire harness fixing device is limited and disposed on the mounting component.

[0014] Preferably, the wire harness fixing device further includes:

[0015] A reinforcing member is disposed on the outer wall of the main body, and both ends of the reinforcing member along the Y-axis are respectively connected to the groove wall of the fixing groove.

[0016] Preferably, the reinforcing member is located on the lower sidewall of the main body along the Z-axis direction.

[0017] Preferably, the reinforcing member is integrally formed with the main body.

[0018] Preferably, the material of the main body is rubber.

[0019] The beneficial effects of this utility model are:

[0020] This wire harness fixing device includes a main body made of elastic material. Multiple receiving cavities are opened through the main body and distributed along the X-axis. The main body has multiple notches that are connected to the receiving cavities. The width of the notches is smaller than the diameter of the cable, allowing the cable to be squeezed into the receiving cavity through the notches.

[0021] The main body is made of elastic material, giving this wire harness fixing device high flexibility. This ensures that it can quickly return to its original state under external force, resisting breakage and deformation, thus guaranteeing the reliability and durability of the wire harness fixing. The main body has multiple accommodating cavities to accommodate and fix the individual cables in the wire harness. Because the main body is made of elastic material, the cables can be squeezed into the accommodating cavities through the notches under a certain compressive force. Furthermore, since the width of the notches is smaller than the diameter of the cables, the cables are unlikely to detach on their own, achieving a stable fixing effect. Since the multiple accommodating cavities are distributed along the X-axis, all cables in the wire harness are at the same height when housed in each cavity, avoiding the risk of water ingress due to cable height differences. The wire harness fixing device provided by this utility model effectively solves the problems of limited fixing effect, easy deformation and detachment, and height differences among the cables in traditional cable ties, achieving a stable fixing of the wire harness, improving the reliability and stability of the wire harness fixing, and thus improving the safety of the entire vehicle.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0034] In automotive high-voltage wiring harness design, cable ties are typically used to secure the harness and prevent it from shifting or moving during operation, thus avoiding friction or collision with surrounding parts. However, the securing effect of cable ties is limited. During harness movement, the cable ties may deform under stress, leading to detachment or breakage, resulting in harness fixation failure. In such cases, the harness may interfere with surrounding parts, causing wear and affecting overall vehicle safety. Furthermore, because the heights of the cables within the cable-tied harness vary, a height difference exists between the cable insertion point and the cable tie fixing point. This height difference can cause stress at the insertion point, deforming the cable seal and increasing the risk of water ingress into the insertion point.

[0035] To solve the above problems, such as Figure 1 , Figure 2 As shown, this embodiment provides a wire harness fixing device. This wire harness fixing device includes a main body 1, which is made of an elastic material. A plurality of receiving cavities 11 are provided through the main body 1, and the plurality of receiving cavities 11 are distributed along the X-axis direction. The main body 1 has a plurality of notches 12, which are correspondingly connected to the receiving cavities 11. The width of the notch 12 is smaller than the diameter of the cable, so that the cable can be squeezed into the receiving cavity 11 through the notch 12.

[0036] The main body 1 is made of elastic material, giving this wire harness fixing device high flexibility. This ensures that it can quickly return to its original state when subjected to external force, preventing breakage and deformation, and guaranteeing the reliability and durability of the wire harness fixing. The main body 1 has multiple receiving cavities 11 to accommodate and fix the individual cables in the wire harness. Because the main body 1 is made of elastic material, the cables can be squeezed into the receiving cavities 11 through the notches 12 under a certain compressive force. Furthermore, since the width of the notches 12 is smaller than the diameter of the cables, the cables are unlikely to detach on their own, achieving a stable fixing effect. Since the multiple receiving cavities 11 are distributed along the X-axis, all cables in the wire harness are at the same height when housed in each cavity 11, avoiding the risk of water ingress due to height differences between cables. The wire harness fixing device provided in this embodiment effectively solves the problems of limited fixing effect, easy deformation and detachment, and height differences between the individual cables in traditional cable ties, achieving stable fixing of the wire harness, improving the reliability and stability of the wire harness fixing, and thus improving the safety of the entire vehicle.

[0037] In this embodiment, the main body 1 is made of rubber. Rubber has good flexibility and resilience, and can quickly return to its original state when subjected to external force, making it less prone to breakage and deformation. Rubber also has excellent high-temperature resistance and corrosion resistance, maintaining stable performance under various conditions to ensure the reliability and safety of the wire harness fixation. In other embodiments, the main body 1 may also be made of elastic materials such as silicone or thermoplastic elastomer (TPE), and this embodiment does not limit this.

[0038] It should be noted that the number of accommodating cavities 11 and the location of the notches 12 are determined by actual needs, and this embodiment does not limit them. For example, as shown... Figure 1 , Figure 2 As shown, there are two accommodating cavities 11, which are distributed along the X-axis. There are also two notches 12, which are located on both sides of the main body 1 along the X-axis.

[0039] In one alternative embodiment, such as Figures 1-3 As shown, the wire harness fixing device also includes a limiting component 2, which includes two limiting members 21. The two limiting members 21 are spaced apart along the Y-axis on the outer wall of the main body 1. The mounting component can be engaged between the two limiting members 21, so that the wire harness fixing device is fixed on the mounting component. By setting the limiting component 2, the position of the wire harness fixing device on the mounting component is limited, which can prevent the wire harness fixing device from shifting when it is fixed to the mounting component, making the installation quicker and more convenient.

[0040] It should be noted that the wiring harness fixing device is used to securely fasten the various cables of the wiring harness, and the mounting component is used to provide an installation position for the wiring harness fixing device, so that the wiring harness secured by the wiring harness fixing device can be fixed to the vehicle. In some embodiments, the mounting component is a sheet metal part 100 of the vehicle; in other embodiments, the mounting component may also be a part fixedly installed in the vehicle. This embodiment does not limit the specific form and structure of the mounting component.

[0041] In some embodiments, such as Figure 1 , Figure 2 As shown, the limiting member 21 extends along the outer peripheral surface of the main body 1. That is, the limiting member 21 is arranged around the outer peripheral surface of the main body 1. On the one hand, this arrangement of the limiting member 21 can provide a uniform limiting effect, ensuring a more accurate relative position between the main body 1 and the mounting part, which helps to reduce assembly errors; on the other hand, the limiting member 21 can prevent the main body 1 from deforming or displacing when subjected to force, thereby enhancing the structural strength.

[0042] In other embodiments, there are multiple sets of limiting components 2, which are spaced apart around the outer peripheral surface of the main body 1. Multiple sets of limiting components 2 enable the main body 1 to distribute stress more evenly when subjected to external forces, reducing the risk of deformation and displacement.

[0043] Specifically, the limiting component 2 is integrally formed with the main body 1. The integral forming design eliminates the need for additional connectors or fixing methods between the limiting component 2 and the main body 1, thereby reducing structural instability caused by loose or failed connections. The integral forming design simplifies the manufacturing process, reduces assembly steps and the number of required parts in the production process, lowers production costs, and improves production efficiency.

[0044] In another optional embodiment, a fixing groove is provided on the outer periphery of the main body 1, and the mounting component can be disposed in the fixing groove so that the wire harness fixing device is limited and disposed on the mounting component. The fixing groove provides a precise positioning reference for the installation of this wire harness fixing device, ensuring that the wire harness fixing device can be accurately and stably installed on the mounting component, and preventing the wire harness fixing device from shifting when fixed to the mounting component, making the installation faster and more convenient, reducing assembly errors, and improving assembly efficiency.

[0045] Specifically, such as Figure 2 As shown, this wire harness fixing device also includes a reinforcing member 3, which is disposed on the outer wall of the main body 1. Both ends of the reinforcing member 3 along the Y-axis are connected to the groove walls of the fixing groove. The reinforcing member 3 connects the two groove walls along the Y-axis of the fixing groove, thereby enhancing the overall structural strength of the wire harness fixing device and improving its stability. Under dynamic environments such as vibration or impact, the reinforcing member 3 can reduce the deformation of the main body 1, ensuring that the wire harness fixing device maintains a stable fixing effect.

[0046] Furthermore, such as Figure 2 As shown, the reinforcing member 3 is located on the lower side wall of the main body 1 along the Z-axis. It can be understood that when this wire harness fixing device is installed on the mounting component, the reinforcing member 3 is located on the supporting surface of the mounting component. The reinforcing member 3 can more effectively disperse and transfer stress from the mounting component and the cable, which helps to reduce stress concentration; the design of the reinforcing member 3 can be coordinated with the overall shape of the main body 1, improving the overall aesthetics of the wire harness fixing device.

[0047] Specifically, the reinforcing member 3 is integrally formed with the main body 1. The integral forming design eliminates the need for additional connecting parts or fixing methods between the reinforcing member 3 and the main body 1, thereby reducing structural instability caused by loose or failed connections. The integral forming design simplifies the manufacturing process, reduces assembly steps and the number of required parts in the production process, lowers production costs, and improves production efficiency.

[0048] In the specific implementation process, when opening the fixing groove, the above-mentioned reinforcing member 3 can be formed by avoiding the lower side wall of the main body 1 along the Z-axis direction.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
