DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 4 , the utility model provides embodiments:

[0023] The embodiment of the present application discloses a stretch-resistant automotive low-voltage wiring harness, including a wiring harness body 1, a first protective cover 2 and a second protective cover 3. The first protective cover 2 is located on the front of the second protective cover 3. The first protective cover 2 and the second protective cover 3 are both sleeved on the surface of the wiring harness body 1. The first protective cover 2 is hinged with a first movable rod 6 on all sides of the inner wall through a first hinge seat 5. The ends of the first movable rod 6 are hinged with a second movable rod 8 through a connecting buckle. The ends of the second movable rod 8 are hinged to the inner wall of the second protective cover 3 through a second hinge seat 9. Sealing mechanisms are provided on the inner sides of the first protective cover 2 and the second protective cover 3.

[0024] As a technical optimization solution of the utility model, when the first protective cover 2 and the second protective cover 3 are stretched, the first movable rod 6 and the second movable rod 8 will swing under the action of the first hinge seat 5 and the second hinge seat 9, thereby providing a stable connection for the first protective cover 2 and the second protective cover 3, which can effectively improve the tensile resistance of the automobile wiring harness;

[0025] It should be noted that the length of the wire harness body 1 may be greater than the total length of the first protective cover 2 , the second protective cover 3 and the outer tube 14 , thereby avoiding the first protective cover 2 and the second protective cover 3 from causing adverse effects on the wire harness body 1 when stretched.

[0026] The sealing mechanism comprises a sealing plate 10 fixedly mounted on the front side of the second protective sleeve 3 . A sealing groove 11 is provided on the back side of the first protective sleeve 2 . The sealing plate 10 is slidably connected to the inner cavity of the sealing groove 11 .

[0027] As a technical optimization solution of the utility model, when the first protective cover 2 and the second protective cover 3 are stretched, the wiring harness body 1 inside will leak out. At this time, the sealing plate 10 and the sealing groove 11 can be used to seal the wiring harness body 1, thereby preventing the wiring harness body 1 from being exposed to the outside.

[0028] The second protective sleeve 3 is fixedly mounted with sliding sleeves 12 on all sides of the surface, and the front side of the sliding sleeves 12 is slidably connected with sliding rods 13 . The sliding rods 13 are fixedly mounted on all sides of the surface of the first protective sleeve 2 .

[0029] As a technical optimization solution of the utility model, when the first protective sleeve 2 and the second protective sleeve 3 are stretched, the slide rod 13 will slide in the inner cavity of the slide sleeve 12, thereby limiting and supporting the first protective sleeve 2 and the second protective sleeve 3.

[0030] The outer sides of the first protective sleeve 2 and the second protective sleeve 3 are both fixedly mounted with an outer tube 14, which is composed of a base material layer and a corrosion-resistant layer.

[0031] As a technical optimization solution of the utility model, the corrosion-resistant layer is made of polytetrafluoroethylene material, which can increase the service life of the outer tube 14.

[0032] An insulating tube 15 is sleeved on the surface of the wiring harness body 1 , and the front and back sides of the insulating tube 15 are fixedly connected to the inner wall of the outer tube 14 through connecting blocks 16 .

[0033] As a technical optimization solution of the utility model, the insulating tube 15 is made of polyethylene resin material, which can prevent the wiring harness body 1 from being disturbed by the outside, thereby ensuring its stable operation.

[0034] Working principle: Since the two ends of the wiring harness body 1 are connected by the connecting block 16 and the outer tube 14 respectively, when the wiring harness body 1 is pulled by an external force, the first protective cover 2 and the second protective cover 3 on its surface will be stretched. During this process, the first movable rod 6 and the second movable rod 8 will swing under the action of the first hinge seat 5 and the second hinge seat 9, so that the first protective cover 2 and the second protective cover 3 can be stably connected during the stretching process, thereby avoiding damage or breakage of the wiring harness body 1 under the action of external force, which can effectively improve the safety of use.

[0035] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0036] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. All equivalent changes and modifications to the shapes, structures, features and spirits described in the claims of the present invention should be included in the claims of the present invention.
