Description

  The present invention relates to a terminal block, and more particularly to a separation-type terminal block in which a terminal connector provided with a terminal on the other side is connected to and separated from a terminal base provided with a terminal on one side. It is.

  In general, terminal blocks are used in distribution boards, control boards, and the like for the purpose of connecting, branching, and relaying wires.

  A conventional terminal block has a plurality of terminals and is arranged so that the terminals of each electrode can be connected to each other, and electric wiring is fastened to each terminal by a terminal screw. (For example, refer to Patent Document 1).

  However, in this type of conventional terminal block, when electrical wiring is connected to or removed from the terminals, it is necessary to fasten or loosen the terminal screws one by one, which is very troublesome. there were.

  Therefore, in order to solve this type of problem, in recent years, a terminal base provided with one terminal is separated from a terminal connector provided with the other terminal so that the terminal connector can be coupled and separated. A terminal block of a type has been proposed (see, for example, Patent Document 2).
