Description

Technical Field

[0001] The utility model relates to a wire harness clip, in particular to a wire harness clip with a limiting function. Background Art

[0002] Cable harnesses are common parts in various equipment and systems, and play an important role in communication and power transmission. In various equipment and systems, cable harnesses are often fixed with harness ties or harness clips for ease of operation and suitability for different scenarios. However, the fixing effect of harness ties is greatly affected by human factors, and has disadvantages such as poor standardization and automation. In the application of heavy trucks and various engineering vehicles, harness ties exposed outside the cockpit are easily affected by the harsh working environment, aging or even breaking.

[0003] In the prior art, to solve this problem, heavy trucks and various engineering vehicles often use metal harness clips to fix cable harnesses. However, heavy trucks and various engineering vehicles are accompanied by vibration during operation, which will cause continuous friction between the metal harness clips and the insulation layer of the cable harness, which can easily cause the insulation layer of the cable harness to wear and fail, posing certain safety hazards.

[0004] In addition, metal harness clips are generally fixed with mounting bolts during installation, which places high demands on the installation direction. This requires the metal harness clips to actively adjust the installation angle to ensure that the installation direction is correct, which results in low assembly efficiency.

[0005] In order to solve the problem that metal harness clips are prone to cause cable harness wear under vibration conditions, a Chinese patent with publication number CN205051262U discloses a harness clip bracket for automobiles, including a bracket body, characterized in that a positioning structure is provided at one end of the bracket body, the positioning structure is vertically connected to the bracket body, a first bracket fastening hole is provided on the bracket body and near the positioning structure, a harness fixing frame vertically connected to the bracket body is provided on the bracket body, a harness fixing hole is provided on the harness fixing frame, a harness auxiliary clamping piece is provided on the upper side of the harness fixing frame, and the plane where the harness auxiliary clamping piece is located is parallel to the plane where the harness fixing frame is located. However, the harness clip bracket for automobiles disclosed in this scheme cannot achieve limited orientation.

[0006] To solve the problems of inconvenient installation and the need for adjustment of wire harness clips, as well as the lack of aesthetics due to interference between cable wire harnesses, a wire harness bracket for the position of the automotive A-pillar, with the publication number CN217396412U, is disclosed in a Chinese patent. It includes a bracket body, which is connected to the automotive A-pillar through bolts and an L-shaped limiting structure; multiple groups of wire harness fixing structures are arranged side by side on the bracket body. The wire harness fixing structure includes a chuck fixing structure and a cable tie fixing structure. However, the wire harness bracket for the position of the automotive A-pillar disclosed in this solution has a relatively complex structure and is limited to use at the position of the automotive A-pillar.

DETAILED DESCRIPTION

[0035] The specific technical solutions in the embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0036] See also Figure 1 and Figure 2 , a wiring harness clip with a limiting function, comprising a long strip plate body 1 made of 65Mn with high strength and high elastic limit, and a rounded structure is arranged at the four corners of the plate body 1;

[0037] The plate body 1 comprises a mounting section 7, a reinforcement section 8, a bending section 9 and a guide section 10 which are connected in sequence;

[0038] The mounting section 7 is provided with a mounting hole 6, which is used to cooperate with the mounting bolt 11 to fix the mounting section 7 on the external device;

[0039] The bending section 9 is formed by bending the plate 1 in an arc shape, and the arc angle corresponding to the bending portion is recorded as F, then 200° <F<250°;

[0040] A first reinforcing rib 3 and a second reinforcing rib 4 are provided on one side of the reinforcing section 8 close to the bending direction of the bending section 9, and the distances between the first reinforcing rib 3 and the second reinforcing rib 4 and the two sides of the reinforcing section 8 are equal, and the extension direction is consistent with the extension direction of the reinforcing section 8; a limiting plate 2 is provided on the other side of the reinforcing section 8;

[0041] The side of the reinforcing section 8 close to the bending direction of the bending section 9 is recorded as the main view surface, and the mounting section 7 is located at the top and the reinforcing section 8 is located at the bottom, then the limiting plate 2 is arranged on the lugs on the left and right sides of the reinforcing section 8, and extends in the direction away from the bending direction of the bending section 9, and is formed by bending the lugs, and the limiting plate 2 is used to abut against the edge of the external device to limit the rotation of the plate body 1;

[0042] The end of the guide section 10 extends in a direction away from the reinforcement section 8;

[0043] The guide section 10 and the bending section 9 are connected by an arc transition;

[0044] A non-metallic material coating area 5 is provided on the plate body 1 . The non-metallic material coating area 5 is a non-metallic material area covering a portion of the surface of the plate body 1 .

[0045] In the harness clip, the mounting hole 6 uses the original bolts and other fasteners on the target device to fix the harness clip;

[0046] The non-metallic material covering area 5 includes a guide section 10, a bending section 9, and a partial area of ​​a reinforcement section 8, which is used to prevent the metal surface of the harness clip from contacting the cable harness.

[0047] The working principle of the embodiment of the utility model is as follows:

[0048] See also Figure 3 The wiring harness clip provided in the embodiment of the utility model uses a fastener such as a mounting bolt 11 to fix the wiring harness clip to a device such as a gearbox through a mounting hole 6 during installation. Under the action of friction, the rotation of the mounting bolt 11 will drive the wiring harness clip to rotate together.

[0049] Since the harness clip itself has a limit plate 2, the plate body 1 will be restricted when it rotates to a pre-designed position. At this time, the limit plate 2 interferes with the device body, making it impossible for the plate body 1 to continue rotating, thereby achieving the purpose of limiting and orienting the harness clip.

[0050] The position and number of the limit plates 2 on the plate body 1 can be designed and adjusted according to actual needs and the shape of the equipment body. The cable harness is installed in the bending section 9 of the harness clip. Since the bending section 9 is covered with non-metallic material, the cable harness can be prevented from being worn by the edge of the metal harness clip; and the reinforcing rib 3 / 4 protruding inward on the harness clip can prevent the cable harness from falling off the harness clip.

[0051] The above description is only an embodiment of the present utility model and is not intended to limit the protection scope of the present utility model. Any equivalent structural transformation made using the contents of the present utility model specification and drawings, or directly or indirectly applied in other related technical fields, is included in the patent protection scope of the present utility model.
