[0002] The wiring harness is a carrier used to provide current, signals or other substances between different devices. The wiring harness is composed of multiple cables to form a thicker cable.

[0003] For example, Publication No. CN104205539B, titled "Wiring Harness Protector and Wiring Harness," provides a wiring harness protector and wiring harness that offer excellent protection even under high temperature and high humidity conditions. The wiring harness is constructed by covering the surrounding area of ​​the wires with a wiring harness protector formed from a nonwoven fabric molded into a predetermined shape.

[0004] The above device is not convenient for separating different cables during use. When the wiring harness is used, the wiring harness is stretched and laid, which easily causes the inside of the wiring harness to be broken, affecting the use effect of the wiring harness. It is inconvenient to adjust the wiring harness at multiple angles when laying it, which easily causes the internal wires of the wiring harness to be broken when adjusting the direction at multiple angles, affecting subsequent use. Therefore, we have proposed a wiring harness with good protection to solve the above problems. Utility Model Content

[0019] 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 the embodiments.

[0020] See also Figure 1-4 The utility model provides an embodiment: a wiring harness with good protection, including a wiring harness drum 1, an air bag 2 is installed on the inner wall of the wiring harness drum 1, a plurality of limiting tubes 3 are installed on the inner wall of the air bag 2, a plurality of groups of balls 5 are embedded in the inner wall of the limiting tube 3, a wiring harness core 4 is installed inside the limiting tube 3, a protective shell 6 is installed on the outer wall of the wiring harness drum 1, an air intake valve 7 is installed on one side of the top of the wiring harness drum 1, an exhaust valve 8 is installed on the other side of the top of the wiring harness drum 1, two adjacent wiring harness drums 1 are connected by a connecting tube 9, an insulating layer 10 is installed on the outer wall of the wiring harness core 4, and a flame retardant layer 12 is installed on the outer wall of the insulating layer 10.

[0021] See also Figure 2 and Figure 3 The balls 5 are evenly distributed on the inner wall surface of the airbag 2. The balls 5 can provide support for the harness core 4 and reduce the friction of the harness core 4 when rolling or moving.

[0022] See also Figure 2 and Figure 3 The limiting tube 3 is made of rubber, and has elasticity and insulation properties, making it easy to limit the wiring harness cores 4 of different diameters through the limiting tube 3.

[0023] See also Figure 1 The connecting tube 9 is a corrugated tube structure, which facilitates the bending of the wiring harness and does not cause damage to the outer skin of the wiring harness while not reducing the strength of the wiring harness.

[0024] See also Figure 2 The intake valve 7 and the exhaust valve 8 are connected to the interior of the airbag 2. The intake valve 7 and the exhaust valve 8 are one-way valves, which facilitate filling the airbag 2 with air through the intake valve 7 and exhausting the air inside the airbag 2 through the exhaust valve 8. The setting of the one-way valve can prevent the gas inside the airbag 2 from flowing back.

[0025] See also Figure 4 A filling layer 11 is installed between the insulating layer 10 and the flame retardant layer 12. The filling layer 11 is filled with air. The filling layer 11 can provide protection and buffering for the wiring harness core, thereby preventing damage to the wiring harness core 4 when the limiting tube 3 limits the wiring harness core 4.

[0026] Working principle: When in use, multiple wire harness cores 4 are placed inside the limiting tube 3, and cold air is injected into the airbag 2 through the air inlet valve 7 to expand the airbag 2. The expansion of the airbag 2 can squeeze the limiting tube 3 to limit the wire harness core 4. The setting of the insulation layer 10 and the flame retardant layer 12 protects the wire harness core 4 from damage during the transmission of electrical energy or signals and ensures safety. The filling layer 11 is filled with air, which can provide protection and buffering effect to the wire harness core, avoiding the wire harness core 4 from being damaged when the limiting tube 3 limits the wire harness core 4. In the event of damage to the harness core 4, the protective shell 6 can provide buffering and protection for the entire wiring harness. When the wiring harness needs to be adjusted at multiple angles, the air inside the airbag 2 is discharged through the exhaust valve 8, and the limiting tube 3 cancels the fixation of the harness core 4. The connecting tube 9 is a bellows structure, which is convenient for the bending of the harness and will not cause damage to the outer skin of the harness without reducing the strength of the harness. The rolling of the ball 5 can move the harness core 4 when the angle of the harness is adjusted, preventing the harness core 4 from being broken when the angle of the harness is adjusted.

[0027] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
