Description

Technical Field

[0001] The utility model relates to the technical field of cable equipment, in particular to a wear-resistant cable. Background Art

[0002] The structure of wires and cables mainly includes several parts such as conductor, insulation layer, and sheath; the conductor is the transmission channel of electric current and is usually made of metal materials such as copper or aluminum. The insulation layer is used to wrap the conductor to prevent current leakage and short circuit. Common insulating materials include polyethylene, polyvinyl chloride, etc.

[0003] Currently, cables need to be pulled during use, which causes the cables to rub against the ground during use, which can easily cause the outer surface sheath or insulation layer of the cable to rupture and penetrate, and then easily cause the internal conductor to be exposed, resulting in current leakage and short circuit. Therefore, a wear-resistant cable is needed to change the current situation. Utility Model Content

[0004] In view of the above problems, the utility model provides a wear-resistant cable. When the cable is pulled, even if its insulating sheath or insulating layer is damaged, the internal protective component cover can protect the conductor accordingly to prevent the internal conductor from being worn and exposed to the outside, causing current leakage and short circuit.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical solutions: a wear-resistant cable, comprising several conductors, a protective component is nested outside the conductor, an insulating layer is nested outside the protective component, and a sheath is nested outside the insulating layer; an inner support column is arranged inside the protective component, and several protective covers are connected outside the inner support column, and a conductor slot is formed between the inner support column and the protective cover. The conductor slot is mainly used for the conductor to be locked and stored, and the inner part is supported by the inner support column, and the outer part is protected by the protective cover, so that when the outer insulating layer and the sheath are damaged, the protective component protects the conductor to prevent the conductor from being worn and exposed to the outside.

[0006] Furthermore, a fixing block is fixed on the inner support column, a locking sleeve is arranged at a position opposite to the fixing block, a pin rod is passed through the locking sleeve, and the locking sleeve is connected to the protective cover through the pin rod. The pin rod passed through the locking sleeve is mainly used to cooperate with the protective cover to cover the conductor after the conductor is installed, and the protective cover is locked after the pin rod passes through it, so as to prevent the protective cover from opening and closing during use and prevent the internal conductor from escaping from the conductor slot.

[0007] Furthermore, the protective cover is provided with a cover body, one end of which is provided with a connecting ring, a rotating shaft rod is passed through the connecting ring, and the other end of which is provided with a plurality of sleeve rod tubes. The connecting ring is fixed to one end of the cover body, and is hingedly matched with the rotating shaft rod passing through the center to form an articulated cooperation with the fixing block, so that the protective cover can form an articulated swing, and then the protective cover can be hingedly opened and closed on the inner support column, so that the conductor can be placed in the conductor slot.

[0008] Furthermore, the cover body is hingedly connected with the fixing block through the rotating shaft rod penetrating the connecting ring, the locking sleeve is arranged between the sleeve rod tube, the pin rod penetrates the sleeve rod tube and the locking sleeve respectively, the conductor is engaged in the conductor slot, the protective assembly engages the conductor, and the outside is nested by the insulating layer. The protective cover is mainly fixed and hingedly connected by the pin rod and the rotating shaft rod in cooperation with the inner support column, so that the protective cover can cooperate with the inner support column to clamp the conductor, thereby ensuring that the conductor forms corresponding protection inside it, and improving the wear resistance of the cable during use.

[0009] Furthermore, the protection component can be made of copper or aluminum metal material.

[0010] Beneficial Effects

When the cable is pulled, even if the insulating layer sheath or the insulating layer is damaged, the internal protective component cover can protect the conductor accordingly to prevent the internal conductor from being worn and exposed to the outside to cause current leakage and short circuit, thereby further improving the wear resistance of the cable.
