Abstract

The invention provides a relay terminal device of a circuit breaker, which is externally arranged on the main circuit terminal of the circuit breaker, and is used for externally connecting electric wires with circular crimping terminals, comprising: a box-shaped casing and an upper cover The insulating frame is combined, wherein, the inside of the box-shaped housing is separated by a partition wall, and there are wire insertion holes corresponding to each of the main circuit in the front, and the upper cover is provided with The operation hole of the terminal screw is covered on the top of the box-shaped casing and is detachably locked with it; the terminal board of each phase is fixed and held in the inside of the box-shaped casing, and its rear end protrudes from the casing to the back; And screwed on the terminal board, the circular crimping terminal of the electric wire inserted in the box-shaped housing is clamped between the terminal board and the terminal screw for fixed connection.

Description

technical field [0001] The present invention relates to a relay terminal device which is suitable for a wiring circuit breaker equipped in a distribution board, a power distribution board, etc., and which is externally installed on a power supply side terminal of the circuit breaker to connect electric wires from a power distribution system. Background technique [0002] As relay terminal devices used for connecting electric wires (such as rubber insulated flexible cables) of the power distribution system to the above-mentioned circuit breakers, there are known relay terminal devices corresponding to U, V, and W phases of the main circuit. a box-shaped terminal connector; and a terminal block (attachment to a circuit breaker) for wire connection in which a terminal board connected between the terminal connector and a main circuit terminal of a circuit breaker is installed in an insulating frame (resin case) (For example, refer to Patent Document 1). [0003] On the other ha...
