Description

Terminal block {TERMINAL BLOCK}

The present invention relates to a terminal block, and more particularly, to a terminal block capable of preventing a mixed contact short circuit accident.

Conventional terminal blocks have a structure in which a plurality of terminals are simply arranged, and a plurality of terminals are exposed in a neighboring state. Accordingly, when a cable is connected to a specific terminal of a terminal block, contact is likely to occur in contact with another neighboring terminal or a terminal connected thereto. Such a contact causes safety accidents such as a large power outage, major electrical and electronic equipment failure, fuse blown, and electric shock.

In order to prevent such a contact accident, the wiring work is performed in a state in which the terminal not connected to the wiring is taped with an insulating tape, but it is difficult to ensure safety and hassle of attaching an insulating tape because the taping operation is performed only by the operator's judgment. Occasional contact occurs due to omission due to omission of the taping operation. In addition, there is a problem that the risk of contact is higher for workers who are not familiar with the wiring work. Therefore, there is a need to improve this.
