Description

Technical Field

[0001] The utility model relates to the technical field of electrical contacts, in particular to an electrical contact connection device for a power plant. Background Art

[0002] Electrical contacts are the main conductive contact materials widely used in relays, contactors, load switches, medium and low voltage circuit breakers, as well as switching electrical appliances such as household appliances and automotive appliances. Their reliability directly affects the reliable operation of the entire power system.

[0003] The patent document with the prior art announcement number CN219998064U provides an electrical contact connection device for a power plant, including a fixed seat and a connection component installed on the surface of the fixed seat; the connection component includes a shell installed on the surface of the fixed seat, a conductive block installed in the shell, a static contact installed in the shell, and a second guide rod installed in the shell and connected to the static contact. The utility model can enhance the stability between the moving contact and the static contact during the use of the electrical switch by installing the connection component, reduce the generation of electric sparks during use, increase the service life of the static contact, and have a good use effect. In combination with the wiring component, it is convenient for the electrical switch to be wired by dragging the pull block to make the wire wrap around the slide rod and reset it through the second spring, making the wiring of the electrical switch more convenient and quick, and having a good use effect.

[0004] However, in the use of the existing power plant electrical contact connection device, the electrical contacts are opened and closed by pushing and pulling the switch during the power connection process. However, when opening and closing, the electrical contacts are not firmly connected to the power. Although they can play the role of power connection, the power connection strength cannot be increased after power connection, resulting in the electrical contacts being separated during vibration and generating electric sparks, resulting in poor use effect of the electrical contact connection device. For this reason, we propose a power plant electrical contact connection device. Utility Model Content
