Description

Technical Field

[0001] The utility model relates to the technical field of electric power installation, in particular to a wiring protection device for electric power installation engineering. Background Art

[0002] Electricity is the main source of power for production and life in today's society. Power cables are often used in urban underground power grids, power station lead-out lines, internal power supply of industrial and mining enterprises, and underwater transmission cables across rivers and seas. At power construction sites, due to the length of the cables, secondary connections of various types of cables are usually involved. In actual operation, the insulation layers of the two ends of the two cables that need to be connected are usually stripped off to expose multiple wire ends, and then the exposed wire ends are wrapped accordingly. Finally, electrical tape is used to wrap and fix the exposed wires at the wrapped position. However, the secondary connection of the cable is sometimes placed in an outdoor environment due to use needs. After a period of wind and rain, the electrical tape is easy to lose its stickiness and separate from the cable, causing the cable to be exposed, which brings great safety hazards.

[0003] Existing cable wiring protection devices generally use a junction box to protect the cable, and the junction box is used to achieve waterproof, dustproof and fixation effects on the cable wiring. However, after the existing cable is fixed by the junction box, the junction box lacks a tensile protection structure, so that when the cable is inadvertently pulled, the wiring point is subjected to excessive tension and becomes loose or even broken. Therefore, a wiring protection device for power installation engineering is proposed. Utility Model Content
