Description

Technical Field

[0001] The present application relates to the field of electrical engineering technology, and in particular to a cable cold-pressed terminal quick connector. Background Art

[0002] In electrical engineering projects such as electrical maintenance projects, electrical inspection projects or electrical emergency projects, there is often a large demand for the use of 220-volt mains electricity. Since three-phase 380-volt power supply terminals are mostly used in electrical engineering, this type of 220-volt mains electricity demand is relatively easy to meet. The traditional solution is to take one phase of the three-phase electricity. When faced with a large demand for 220-volt mains electricity, the output wiring of high-voltage three-phase electricity needs to be treated with caution, which is caused by the traditional wiring scheme. One of the options for the traditional wiring scheme is to take power from each phase of the three-phase electricity separately, which is equivalent to wiring in parallel. This method requires a large space and exposes more live bodies, which can easily cause electric shock accidents. Another method is to choose one phase of the three-phase electricity and use a power strip in parallel to the cables that need power, which can cause the power strip to overload and melt, causing power accidents. To this end, it is necessary to propose a cable cold-pressed terminal quick adapter to address the defects of the traditional power-taking scheme that easily causes power accidents.
