Description

Technical Field

[0001] The utility model relates to the technical field of end protection of wires, and particularly relates to an end protection structure for wires. Background Art

[0002] A wire is a material used for conducting electricity, usually a slender object made of metal, and is used to transmit electric current. Wires are usually used in electrical systems such as circuits, cables, wire harnesses, etc. They have low resistance and can effectively transmit electrical energy. A wire can be a single thin wire or a cable woven or wound by multiple thin wires. In a circuit, a wire plays an important role in transmitting electrical energy from a power source to various electrical appliances or devices.

[0003] However, during the use or storage of wires, due to the lack of a protection structure at the ends of existing wires, the exposed wire ends are likely to cause electric shock accidents, especially when close to the human body or other conductive objects, increasing the risk of electric shock. The exposed wire ends are easily damaged by mechanical collision, extrusion or pulling, resulting in situations such as the wire being bent or squeezed and broken or deformed. The wire ends are easily affected by mechanical damage, oxidation, corrosion and other factors in the external environment, leading to wire breakage or poor contact, affecting the normal operation of the circuit and increasing the possibility of circuit failures.
