Problems solved by technology

The known wire harness fixing method, for example, first fixes the wire harness with a ring, and then locks and fixes the ring with bolts, but this fixing method is not only cumbersome to disassemble, but also needs to be tapped on the structure, which is cumbersome to operate and complicated in structure. And because the bolt is fixed, the contact area between the ring and the bolt is large, and the heat transferred from the high-temperature surface to the ring is relatively large, which will cause deformation of the structure and affect the fixing of the wiring harness.

Embodiment 1

[0031] Such as figure 1 , figure 2 , image 3 As shown, the wire harness fixing device for high-temperature surfaces of the present invention includes a snap ring 1 and a pillar 2. The snap ring 1 is an opening structure, and the size of the opening can be elastically deformed within a certain range, thereby facilitating the passage of the wire harness 4. In, the snap ring 1 includes a ring part 3 to penetrate the wire harness 4 to be fixed, and the two ends of the opening of the ring part 3 are provided with root parts 7 to form the opening part of the snap ring 1, that is to say, the snap ring 1 is made of a profile It is bent and integrally formed, the pillar 2 is connected to the high-temperature surface 9, the top of the pillar 2 is provided with an inner insertion hole 5, and the upper circle of the pillar 2 is provided with a snap ring limit hole 6 communicating with the inner insertion hole 5; the cross section of the ring part 3 It is an arc larger than a semicircl...

Embodiment 2

[0036] Such as Figure 4 , Figure 5 As shown, there are two ring parts 3, and the opening ends on the same side of the two ring parts are connected to each other and share a root 7, that is, the snap ring 1 has a double-ring structure, and there is a gap between the two ring parts 3 , so as to enhance the binding ability of the clasp 1 to the wire harness 4; similarly, by external force acting on the roots 7 at both ends, the roots 7 and hooks 8 at both ends are relatively close together, and then the roots 7 extend into the inner insertion hole 5 , through the elastic force of the snap ring 1 itself, the hook portion 8 on the snap ring 1 is inserted into the stop hole 6 of the snap ring.

Embodiment 3

[0038] Such as Figure 6 , Figure 7 , Figure 10 As shown, the wire harness fixing device used on the high-temperature surface includes two independent snap rings 1, and there is a gap between the ring parts 3 of the two snap rings 1, so as to enhance the restraint ability of the wire harness 4; the snap ring 1 The root portions 7 are arranged adjacent to each other, that is, the inner insertion hole 5 can accommodate the tight root portions 7 of two snap rings 1; the inner diameter of the snap ring limiting hole 6 is not less than the overlapping width of the hook portions 8 of the two snap rings 1 ; In this embodiment, there are 4 snap ring limit holes 6, and they are set on the circumference of the pillar 2 symmetrically in pairs, and the roots 7 of the two independent snap rings 1 extend into the inner insertion hole 5 through external force , and the hooks 8 of the two snap rings 1 on the same side are all inserted into the same snap ring limiting hole 6 .

Abstract

The invention provides a wire harness fixing device for a high-temperature surface and application of the wire harness fixing device. The wire harness fixing device is simple in structure, low in costand convenient to operate and disassemble, and can effectively reduce structural deformation and guarantee wire harness fixing. The wire harness fixing device comprises a clamping ring and a supporting column; the clamping ring comprises a ring part allowing a wire harness to be fixed to penetrate; root parts are arranged at the two ends of the opening of the ring part, so that an opening part ofthe clamping ring can be formed; the supporting column is connected to the high-temperature surface; an inner inserting hole is formed in the top of the supporting column; and a clamping ring limiting hole communicated with the inner inserting hole is annularly formed in the supporting column; the bending directions of the root parts are opposite to that of the ring part, so that the clamping ring can be elastically deformed; hook parts protruding outwards are arranged at the bottom ends of the root parts at the two ends; the distance between the hook parts is larger than the inner diameter of the inner inserting hole; the root parts extend into the inner inserting hole through external force; and the hook parts are inserted into the clamping ring limiting hole through the elastic force of the clamping ring.

Description

technical field [0001] The invention relates to the technical field of vehicle post-processing, in particular to equipment for arranging wire harnesses on high-temperature surfaces, in particular to wire harness fixing devices for high-temperature surfaces and applications thereof. Background technique [0002] When arranging wire harnesses on high-temperature surfaces, the key is to ensure that the wire harnesses are not too close to or even in contact with the high-temperature surfaces, so as to avoid heat damage to the wire harnesses. At present, the exhaust gas after-processor for vehicles is becoming more and more complex, including more and more wiring harnesses of various sensors and actuators. In order to ensure the safety, reliability and durability of the wiring harness, a reasonable wiring harness fixing method must be considered. The known wire harness fixing method, for example, first fixes the wire harness with a ring, and then locks and fixes the ring with bol...
