Therefore, the above terms should not be understood as limiting the present invention.

[0023] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0024] refer to Figures 1 to 3According to a preferred embodiment of the utility model, a two-wire harness integrated fixing structure will be described in detail below, wherein the two-wire harness integrated fixing structure includes a plastic plug 10 and a rubber sleeve 20, wherein the plastic plug 10 includes a coaxially extending limiting collar 11 and two guide arms 12, wherein the limiting collar 11 is provided with a first opening 101, and the two guide arms 12 are connected to the same side of the limiting collar 11 in a symmetrically distributed manner, and the two guide arms 12 cooperate to form two mutually connected and circularly symmetrically distributed limiting channels 102 for coordinating the placement of the wiring harness 30, wherein the two limiting channels 102 are provided with a second opening 103 at the other end that is connected to each other, and the second opening 103 and the two The positions where the limiting channels 102 are connected to each other are all opposite to the first opening 101, and the connecting gap between the two limiting channels 102 is much smaller than the maximum inner diameter of the limiting channels 102. For example, the connecting gap is 1 / 20-1 / 10 of the maximum inner diameter of the limiting channels 102. In this way, the two wiring harnesses 30 can be independently constrained and fixed at the same time. By setting the first opening 101 and the second opening 103, the wiring harness 30 can be quickly inserted into the appropriate position in the limiting channel 102. In addition, the rubber sleeve 20 is sleeved on the surface of the guide arm 12, and a limiting structure is set on the outer surface of the rubber sleeve 20, which is used to install the integrated fixing structure to the corresponding position of the vehicle body frame through the limiting structure.

[0025] In addition, in order to make the integrated fixing structure more effectively integrate and fix the two wiring harnesses 30, the two wiring harness integrated fixing structure also includes a glue layer, wherein the glue layer is connected between the plastic plug 10 and the rubber sleeve 20 in a glue-fixing manner, that is, the wiring harnesses 30 are all inserted into place, and the rubber sleeve 20 and the plastic plug 10 are glue-fixed after assembly to form the glue layer, so that the glue fills the gap between the rubber sleeve 20 and the plastic plug 10, which can further strengthen the integrated fixing structure.

[0026] In one embodiment, the limiting collar 11 and the guide arm 12 are an integrated structure, which is convenient for rapid manufacturing.

[0027] In one embodiment, the opening size of the second opening 103 is smaller than the maximum inner diameter of the limiting channel 102 to prevent the wire harness 30 from being separated from the limiting channel 102 from the position of the second opening 103 .

[0028] In one embodiment, the width of the first opening 101 is 0.4-0.7 mm, such as 0.5 mm.

[0029] In one embodiment, one end of the rubber sleeve 20 abuts against the limiting ring 11, and the length of the rubber sleeve 20 is greater than the length of the guide arm 12. In this way, when the wiring harness 30 is bent, the wiring harness 30 can be effectively protected by the soft and elastic characteristics of the rubber sleeve 20.

[0030] Further preferably, the limiting structure includes a limiting groove 201 annularly opened at one end of the rubber sleeve 20 close to the plastic plug 10 and a T-shaped limiting block 21 vertically embedded in the limiting groove 201 in an interference fit manner, and the horizontal portion 211 of the T-shaped limiting block 21 remains perpendicular to the extension direction of the guide arm 12.

[0031] In order to facilitate the rapid and accurate insertion of the plastic sleeve onto the plastic plug 10, it is further preferred that an easy-to-thread tube avoidance channel 202 is provided on the inner wall of the rubber sleeve 20 at the end away from the plastic plug 10, so that a gap is maintained between the outer surface of the guide arm 12 and the easy-to-thread tube avoidance channel 202 to reduce the contact area between the rubber sleeve 20 and the plastic plug 10, while the rubber sleeve 20 can also maintain the protective effect on the wiring harness 30.

[0032] Further preferably, the outer surface of the rubber sleeve 20 is provided with a concave arc structure 22 opposite to the easy-penetration tube avoidance channel 202, so that the rubber sleeve 20 can be thinned opposite to the easy-penetration tube avoidance channel 202, which can reduce the weight of the integrated fixed structure to a certain extent and save raw materials. At the same time, the rubber sleeve 20 is easier to bend while maintaining the protective strength, which can further enhance the protective effect of the wiring harness 30.

[0033] Further preferably, the concave arc surface structure 22 is axially provided with a first end and a second end that are relatively distributed, wherein the first end is close to the limiting ring 11, and the outer diameter of the first end is greater than the outer diameter of the second end, and the outer diameter of the second end is greater than the outer diameter of the lowest point of the concave arc surface structure 22. In this way, the thickness of the second end can be increased through this warped structure, thereby enhancing the structural strength at the second end, and even if problems such as frequent bending and wear occur, it can have a longer service life.

[0034] It should be noted that the terms "first, second" in the present invention are only used for descriptive purposes and do not indicate any order. They cannot be understood as indicating or implying relative importance. These terms can be interpreted as names.

[0035] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
