Background

The electric wire refers to a wire for transmitting electric energy. The bare wires, the electromagnetic wires and the insulated wires. The bare wires have no insulating layer and comprise copper, aluminum flat wires, overhead stranded wires and various profiles (such as molded lines, bus bars, copper bars, aluminum bars and the like). It is mainly used for outdoor overhead and indoor bus bars and switch boxes. Magnet wires are insulated wires that, when energized, produce a magnetic field or induce a current in a magnetic field. It is mainly used for motor and transformer coils and other relevant electromagnetic equipment. The conductor is mainly a copper wire, and has a thin insulating layer, good electrical and mechanical properties, heat resistance, moisture resistance, solvent resistance and the like. Different insulating materials are selected to achieve different characteristics.

The power line is a wire that transmits current. The usual way of current transfer is point-to-point transfer. The power line can be divided into an AC power line and a DC power line according to the purpose, generally, the AC power line is a wire rod passing through AC with higher voltage, and the wire rod needs to be unified standard due to higher voltage so as to obtain a safety certification party and can be formally produced. The DC line passes a direct current with a low voltage, so that the safety requirement is not strict as the AC line, but the countries still require uniform safety certification for safety.

The outer sheath is a structural part for maintaining an insulating layer of the power line to avoid corrosion of condition elements. The outer sheath has the first effects of improving the mechanical strength, chemical corrosion resistance, moisture resistance, water and immersion resistance, preventing the power line from burning and the like of the power line. And directly extruding the plastic sheath by using an extruding machine according to the divergence requirement of the power line.

Application number is CN201720239261.8, the name is a utility model patent of high strength wire protective sheath, including the protective sheath body, this protective sheath body is equipped with the central through-hole that supplies the wire to pass, its characterized in that, the protective sheath body is equipped with the lateral part through-hole more than two at the lateral part of central through-hole, the lateral part through-hole inlays and is equipped with the enhancement metal wire, the even impression of enhancement metal wire surface has the indenture. Through set up the lateral part through-hole more than two at the protective sheath body and inlay at the lateral part through-hole and be equipped with the enhancement metal wire to make wire protective sheath bulk strength high, have good tensile, anti buckling performance. Moreover, the metal wire surface is uniformly stamped with dents, the combination with the protective sleeve is stable and reliable, and the situation of loosening and separation can not occur.

However, at present, a power line or a lead wire is worn due to long-term use, the lead wire is exposed and easy to break, so that an instrument cannot be used or electric leakage is caused, potential safety hazards exist, and the original method of winding and wrapping the lead wire by using an insulating adhesive tape is very time-consuming and inconvenient, so that a lead wire protective sleeve is designed.
