Description

Technical Field

[0001] The utility model belongs to the field of cables, and in particular relates to a cable harness with a self-repairing function. Background Art

[0002] Maintenance lights are widely used in various construction operations such as railways, electric power, public security, etc., accident repairs, disaster relief and other work sites. At present, in the process of repairing equipment, maintenance lights are needed to achieve the purpose of lighting, but the existing maintenance lights cannot be quickly wired. When wiring is required, screw wiring is required. When using, the user first needs to loosen the screws, then insert the cables, and finally tighten the screws again; the operation is complicated, which not only wastes time, but also wastes manpower and material resources, and delays the maintenance time. Therefore, a maintenance light with quick wiring has been developed. When in use, it only needs to be inserted into the side wall of the cable to achieve quick wiring. However, during the use of this solution, holes will appear in the side wall of the cable, causing certain safety hazards. Therefore, a cable harness with self-repair function is proposed. Utility Model Content

[0003] The purpose of the utility model is to solve the problems in the background technology and provide a cable harness with a self-repairing function.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A cable harness with a self-repairing function includes a conductor, the conductor is wrapped with an insulating material, a plurality of sealing rings are arrayed on the conductor, the inner ring of the sealing ring is fixedly connected to the conductor, the outer ring of the sealing ring is fixedly connected to the inner wall of the insulating material, and a sealant is filled between the sealing ring and the conductor, and the sealant is a sealant with strong viscosity.

[0006] When the terminal of the inspection light is inserted into the insulating material to form a hole in the cable, the sealant will flow into the hole punctured by the insulating material to fill it, thereby self-repairing the wire and preventing the hole from being generated to cause a safety hazard. At the same time, the sealant is sealed in a section of the cable through the sealing ring. When the user needs to cut the cable during use, he only needs to cut the cable at the position with the sealing ring to prevent leakage of the sealant during the cutting process.

[0007] Preferably, a red mark is provided at the position where the insulating material is provided with a sealing ring. Since a sealing ring is provided every 1 to 2 cm on the conductor, the red mark can be used to measure the distance, so that the position of the sealing ring can be more clearly identified, which is convenient for users to use.

[0008] The length of the sealing ring is 1-3 cm. A sealing ring is arranged on the conductor every 1-2 cm, and the conductor is formed by twisting multiple copper wires.

[0009] Preferably, the outer ring of the sealing ring is provided with a limiting groove along the circumferential direction, and the contact area between the insulating material and the sealing ring can be increased through the limiting groove, so that the sealing ring can be firmly fixed to the insulating material.

[0010] Preferably, a cable tie is further provided on the outside of the insulating material, and the cable tie includes a rolled strip body and a locking head integrally formed with the rolled strip body, the rolled strip body is provided with a wedge tooth area, the locking head is provided with a fastening hole, a positioning lock tongue matching the wedge tooth area is provided in the fastening hole, and a tie ring is formed after the rolled strip body passes through the fastening hole of the locking head, and a wire clamping hole is also provided on the locking head along a direction perpendicular to the extension direction of the rolled strip body.

[0011] The utility model allows a single cable harness to pass through the clamping hole on the locking head, thereby connecting the cable tie as a whole to the cable harness. The cable tie will not fall off the cable harness, thereby effectively preventing the cable tie from being lost. When it is necessary to fold and store the cable tie, a clamping hole perpendicular to the extending direction of the strip body is provided on the locking head. Since a binding ring can be formed after the strip body passes through the fastening hole of the locking head, the cable harness can be bundled up with the binding ring to make it more neat and not scattered.
