DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention. Example 1

[0028] A bending-resistant electronic wiring harness, in order to improve the bending-resistant effect, such as Figure 1-5 As shown, it includes a wiring harness body supported by a supporting assembly, the wiring harness body includes a core wire 9 and a shielding layer 10, the shielding layer 10 is installed on the outer surface of the core wire 9 by wrapping, and a flame retardant layer 8 is fixed on the outer surface of the shielding layer 10, and a waterproof layer 11 is installed on the outer wall of the flame retardant layer 8 by sleeve connection, and the outer surface of the waterproof layer 11 is wrapped with a hard wear-resistant layer 1;

[0029] The support assembly includes a U-shaped seat 4, a connecting rod 6 and a center plate 7, wherein the connecting rod 6 is integrally formed on the outer wall of the center plate 7, and the U-shaped seat 4 is welded to one end of the connecting rod 6 away from the center plate 7;

[0030] Wrapping the shielding layer 10 on the core wire 9 can reduce the interference of external signals on the core wire 9. The flame retardant layer 8 and the waterproof layer 11 effectively improve the fire resistance and waterproofness of the core wire 9. The hard wear-resistant layer 1 has the characteristics of wear resistance and high hardness, which can improve the bending resistance of the wire harness body to a certain extent. When the length of the wire harness body is long, it is connected according to Figure 1 The wire harness is bundled in a spiral manner, and during the bundling process, the wire harness body is spirally wound around the inner surface of the U-shaped seat 4, so that the U-shaped seat 4 and the connecting rod 6 support the wire harness. When the wire harness body is subjected to a large external force during transportation and movement, the support component prevents the wire harness body from being deformed too much and causing damage.

[0031] Furthermore, the wiring harness body also includes a male end connector 2 and a female end connector 3, and the male end connector 2 and the female end connector 3 are respectively installed at both ends of the core wire 9 by insertion;

[0032] When in use, the male connector 2 and the female connector 3 are respectively installed on two sets of transmission equipment to achieve signal transmission.

[0033] Working principle: After the wiring harness body is assembled, it is wrapped around the inner walls of multiple sets of U-shaped seats 4, so that the U-shaped seats 4 and connecting rods 6 can support the wiring harness body. When the wiring harness body needs to be transported, the support assembly can effectively prevent the wiring harness body from bending, which can cause damage to the wiring harness body. Example 2

[0034] A bending-resistant electronic wiring harness, such as Figure 1-5 As shown, in order to facilitate the fixation of the wiring harness body; this embodiment makes the following supplements on the basis of embodiment 1: the outer wall of the wiring harness body is installed with a fixing component, and the fixing component includes a buckle 1 5 and a buckle 2 15, and a slide plate 12 is integrally formed at one end of the buckle 2 15, and a slide groove adapted to the outer diameter of the slide plate 12 is opened at the bottom of the buckle 1 5;

[0035] Buckle 1 5 and buckle 2 15 are used together. The size of the gap between buckle 1 5 and buckle 2 15 can be adjusted by using the slide plate 12 and the slide groove at the bottom of buckle 1 5, so that it can be adaptively adjusted according to the number of circles of the wiring harness body. Buckle 1 5 and buckle 2 15 are clamped outside the wiring harness body to prevent the wiring harness body from exploding during transportation.

[0036] Furthermore, a one-way buckle 17 is integrally formed on the outer wall of one side of the buckle 1 5, and a one-way rack 14 is integrally formed on the outer wall of one side of the buckle 2 15, and the one-way rack 14 and the one-way buckle 17 are used in conjunction with each other;

[0037] In order to effectively avoid the relative stability between the slide plate 12 and the slide groove, when the wiring harness body is bundled, the buckle 1 5 and the buckle 2 15 are relatively slid between the slide plate 12 and the slide groove, so that the inner wall of the buckle 1 5 and the inner wall of the buckle 2 15 are fitted with the outside of the wiring harness body, and the one-way rack 14 is slid along the one-way buckle 17. By utilizing the characteristic that the one-way rack 14 can only move in one direction along the one-way buckle 17, the buckle 1 5 and the buckle 2 15 are clamped around the wiring harness body to ensure the relative stability of the buckle 1 5 and the buckle 2 15.

[0038] Furthermore, the outer wall of one side of the buckle 1 5 and the buckle 2 15 is bonded with a glue layer 16, and the surface of the glue layer 16 is pasted with adhesive paper 13;

[0039] When the harness body needs to be fixed to the housing of the transmission device, after the adhesive paper 13 is torn off, the buckle 1 5 and the buckle 2 15 can be pasted to the housing of the transmission device using the adhesive layer 16, so as to assist in fixing the harness body when it is long.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
