Description

Technical Field

[0001] The utility model relates to the technical field of electric wires, in particular to an electric wire with a protective layer. Background Art

[0002] An electric wire refers to a conductor for transmitting electric energy. It is divided into bare wires, electromagnetic wires, and insulated wires. Bare wires have no insulating layer and include copper and aluminum flat wires, overhead stranded wires, and various profiles. It is mainly used for outdoor overhead lines, indoor busbars, and switch cabinets. Electromagnetic wires are insulated wires that generate a magnetic field after being energized or induce an electric current in a magnetic field. It is mainly used for coils of motors and transformers and other related electromagnetic devices. Its conductor is mainly made of copper wire, and it should have a thin insulating layer, good electrical and mechanical properties, as well as heat resistance, moisture resistance, solvent resistance, etc. Different insulating materials can be selected to obtain different characteristics.

[0003] In the prior art, such as Chinese Patent No.: CN218414024U, an electric wire and cable with a protective layer includes a core body, a shielding protective layer, a connecting component, a protective outer layer, and anti-slip protrusions. The shielding protective layer of the electric wire and cable with a protective layer in the utility model is convenient for isolating the core body from external electromagnetic interference signals, thus effectively ensuring the stability of signal transmission of the core body. The connecting component effectively ensures the rigidity at the connection between the shielding protective layer and the core body, thus effectively ensuring the stability of the connection between the shielding protective layer and the core body. In addition, the design of the protective outer layer is convenient for protecting the outer periphery of the shielding protective layer, effectively extending the service life of the shielding protective layer.

[0004] Although the above solution has the above advantages, the disadvantages of the above solution are that when protecting the electric wire, the traditional protective layer has a single structure and poor wear resistance, resulting in cuts on the electric wire when it is dragged on the ground for a long time, exposing the internal copper wire, and the safety is extremely low. When used manually, electric shock may occur due to careless operation. In addition, the flexibility of the traditional electric wire protective layer is not strong, and after being bent for a long time, the protective layer will be damaged, reducing the practicability of the electric wire protective layer. And when using the electric wire outdoors, strong sunlight will accelerate the aging process of the electric wire insulating material. Common rubber or plastic insulating materials may become hard, cracked, or lose elasticity, resulting in a decrease in the insulation performance of the electric wire, increasing the risk of short circuit or electric leakage, and reducing the safety of the electric wire protective layer.
