Title:
CIRCUIT BREAKER
Document Type and Number:
Japanese Patent JP2017010706
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve the problem that, since the number of distribution lines (man-hours) may be increased in a conventional connection, workability may be reduced, if the number of poles is increased, the number of connections may be increased and much time and efforts may be required and if the number of distribution lines is increased, a work space around a main body may be enlarged and downsizing of a panel may be disturbed.SOLUTION: A circuit breaker comprises three or more sets of switch mechanisms each pairing a first terminal connected to movable and stationary contacts and a second terminal connected to movable and stationary contacts. The circuit breaker also comprises: an U-shaped connection conductor connecting the first terminals or the second terminals of the neighboring switch mechanisms; a dogleg-shaped connection conductor connecting the first terminal of one switch mechanism and the second terminal of the other neighboring switch mechanism; and an insulator which covers a back face of a housing while including a guide groove in which the U-shaped connection conductor and the dogleg-shaped connection conductor are fitted and accommodated. The first terminals and the second terminals of the mutually neighboring switch mechanisms are selectively connected by the U-shaped connection conductor and the dogleg-shaped connection conductor, such that two sets of switch mechanisms are connected in series. A terminal for power supply and a terminal for load consist of any terminals of the first terminals and the second terminals.SELECTED DRAWING: Figure 1
