Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a wire harness clamping structure and control assembly. Background Technology

[0002] With the increasing prevalence of electrification and intelligentization in the automotive industry in recent years, car interiors have also undergone revolutionary changes. In particular, steering wheel switches are no longer limited to basic functions such as volume adjustment, song switching, and making and receiving phone calls. They also need to meet higher-level requirements, such as driver assistance features, steering wheel heating, hands-off detection, and linkage with satellite switches.

[0003] The increased functionality of steering wheel switches leads to a greater number of components and denser circuitry, requiring more wiring harness interfaces. Due to factors such as layout and space constraints, the routing of the wiring harness also varies.

[0004] Because the wiring harness has an irregular path after exiting the housing, the harnesses are intertwined and require manual arrangement during installation. Even after the wiring harnesses with inconsistent paths are arranged, they are still difficult to fix and maintain, which seriously affects assembly efficiency and increases labor costs. Utility Model Content

[0005] This application focuses on solving the aforementioned problems by changing the structure of the lower shell, thereby resolving the issues of messy wiring harness routing and difficulty in organization, and improving the ease of assembly.

[0006] Firstly, the wire harness clamping structure provided in this application adopts the following technical solution:

[0007] A wire harness clamping structure, comprising:

[0008] The housing has a wire hole on it;

[0009] Multiple claw structures are evenly distributed around the wire hole, and the claw structures include:

[0010] Matrix;

[0011] An arc-shaped guide portion, one end of which is retractably mounted on the base, and forms an adjustable lead cavity with the end face of the housing.

[0012] Furthermore, a limiting groove is formed in the base, and an elastic element is provided in the limiting groove. One end of the elastic element is connected to the arc-shaped guide portion, and the other end of the elastic element is fixed in the limiting groove.

[0013] Furthermore, there are two claw structures, which are symmetrically arranged relative to the threading hole.

[0014] Furthermore, the upper shell is provided with a guide portion, and the two ends of the guide portion are respectively provided with two claw structures, and the distance between the two claw structures is less than the length of the guide portion.

[0015] Furthermore, the length of the guide portion is 1.2-1.8 times the distance between the two claw structures.

[0016] Furthermore, the end of the arc-shaped guide portion facing away from the base is connected to the guide portion, and the guide portion is telescopically oriented along with the arc-shaped guide portion.

[0017] Furthermore, the end of the guide portion is arc-shaped.

[0018] Further, the housing includes:

[0019] The lower shell has a through hole on it;

[0020] The upper shell has the threading hole and is fitted onto the lower shell. The upper shell and the lower shell together form a lead wire channel that communicates with the threading hole.

[0021] Secondly, this application provides a control assembly including the aforementioned wire harness clamping structure.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This application can effectively limit the wires passing through the wire hole by setting a claw structure. By setting multiple claw structures, several wires can be separated, and the wires can be better fixed in the lead wire cavity formed by the arc-shaped guide and the housing.

[0024] 2. This application uses an elastic element to adjust the size of the lead cavity to match the number of wires inserted into the lead cavity. When the wire is inserted into the lead cavity, the lead cavity will expand, and the elastic element will be in a stretched state. At the same time, the pressure generated by the elastic element in the stretched state further fixes the wire. Attached Figure Description

[0032] It should also be further understood that the term “and / or” as used in this application refers to any combination of one or more of the listed items, and all possible combinations thereof.

[0033] Example 1:

[0034] A wire harness clamping structure, as shown in the reference. Figure 1 and Figure 2 The device includes a housing 1 and multiple claw structures 2. The housing 1 has a wire-passing hole 11. The multiple claw structures 2 are evenly distributed around the wire-passing hole 11. Each claw structure 2 includes a base 21 and an arc-shaped guide 22. The base 21 is fixed on the housing 1. One end of the arc-shaped guide 22 can extend and retract onto the base 21 and form an adjustable lead wire cavity 3 with the end face of the housing 1.

[0035] The housing 1 includes a lower housing 12 and an upper housing 13. The lower housing 12 has a through hole 121, and the upper housing 13 has a wire hole 11. The upper housing 13 is covered and disposed on the lower housing 12, forming a lead wire channel 14 that communicates with the wire hole 11.

[0036] The detachable configuration of the housing 1 facilitates wiring. Specifically, when wiring, the wire can be passed through the through hole 121 and placed on the lower housing 12, and then passed through the upper housing 13 before the upper housing 13 is closed onto the lower housing 12. At this time, the main body of the wire is constrained to the lead-in channel 14.

[0037] When the wire passes through the wire hole 11, it passes through the lead wire cavity 3. The lead wire cavity 3 constrains the wire. When routing the wires, relevant personnel can pass multiple wire bundles through the lead wire cavities 3 corresponding to different claw structures 2 according to the actual layout requirements, so as to achieve the purpose of organizing, classifying and fixing the wires.

[0038] Meanwhile, the adjustable size of the lead cavity 3 can adaptively adjust the size of the space based on the number of wires.

[0039] Specifically, in combination Figure 3 A limiting groove 211 is provided in the base 21, and an elastic element 23 is provided in the limiting groove 211. One end of the elastic element 23 is connected to the arc-shaped guide part 22, and the other end of the elastic element 23 is fixed in the limiting groove 211.

[0040] When the elastic element 23 is in its natural state, the lead cavity 3 is at its smallest size. By pulling the arc-shaped guide 22, the elastic element 23 is stretched, thus expanding the lead cavity 3 to accommodate different numbers of wires. When the wire is inserted into the lead cavity 3, the lead cavity 3 expands, and the elastic element 23 is in a stretched state. At the same time, the pressure generated by the stretched elastic element 23 further fixes the wire.

[0041] It should be noted that this application does not specifically limit the form of the elastic element 23, as long as it can expand or contract accordingly when the arc-shaped guide portion 22 is pulled to expand or contract the lead wire cavity 3, and fix it after the wire passes through. For example, in this embodiment, the elastic element 23 can be set as a spring. In other embodiments, torsion springs, memory foam, etc. can also be used.

[0042] Furthermore, in this embodiment, two claw structures 2 are provided, symmetrically arranged opposite to the wire threading hole 11. The two claw structures 2 facilitate processing and also divide the wire into two groups during wire arrangement, and fix them by the claw structures 2.

[0043] It should be noted that, based on the increase in the number of wires, additional claw structures 2 can be added, such as 3, 4, 5 or even more. After adding claw structures 2, based on the requirement that claw structures 2 be evenly distributed near the lead cavity 3, the arrangement of claw structures 2 needs to be adjusted accordingly.

[0044] Furthermore, referring to Figure 1 The housing 1 is provided with a guide part 4, and the two ends of the guide part 4 are respectively provided with two claw structures 2. The distance between the two claw structures 2 is less than the length of the guide part 4.

[0045] When the wire passes through the lead cavity 3, the part of the wire that passes through can be led out along the end face of the guide part 4. After the end of the wire that extends out is electrically connected to the corresponding equipment, the wire is tightened by fasteners such as cable ties, so that the wire lies flat against the end face of the guide part 4, and the wire is positioned well, that is, the end face of the guide part 4 constrains the wire.

[0046] Furthermore, the length of the guide portion 4 is 1.2-1.8 times the distance between the two claw structures 2. In specific embodiments, the length of the guide portion 4 can be 1.2 times, 1.5 times, or 1.8 times the distance between the two claw structures 2. In this embodiment, the length of the guide portion 4 is set to 1.5 times the distance between the claw structures 2.

[0047] Based on the requirement for the end face of the guide portion 4 to constrain the wire, the end of the guide portion 4 can be made retractable to match the length of the wire harness, thereby further eliminating the need for cable ties. Meanwhile, in this embodiment, the end of the guide portion 4 is arc-shaped to accommodate the meandering shape formed by the wire during routing, allowing the guide portion 4 to better conform to the wire.

[0048] Furthermore, the end of the arc-shaped guide portion 22 facing away from the base 21 is connected to the guide portion 4, and the guide portion 4 is telescopically configured along with the arc-shaped guide portion 22. The telescopically configured guide portion 4 can accommodate changes in the size of the lead cavity 3 and the gaps created by the changes in size, so as to reduce the situation where the constraint effect of some wires is not good when too many wires pass through the lead cavity 3.

[0049] Meanwhile, the upper shell 13 is further provided with baffles 5 on both sides, and the baffles 5 and the end face of the guide part 4 form a wiring groove to enhance the constraint effect of the guide part 4 on the wire.

[0050] Example 2:

[0051] The difference between this embodiment and Embodiment 1 is that a control assembly is also disclosed, including the wire harness clamping structure described in Embodiment 1.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
