Abstract

본 발명의 과제는 고정접점판과 전원측단자 사이에 구동코일을 설비한 것으로서, 구동코일의 폭방향의 소형화를 도모하는 것이다. 해결수단은 케이스의 소호실내에 전원측단자(24), 구동코일(25), 고정접점판(26)을 구비한 고정접촉자(21) 및 절연제제의 측판(29) 사이에 자성제제의 복수매의 그리드판(30)을 상하로 다단에 걸치도록 갖는 소호장치(22)를 배치설비한다. 전원측단자(24), 구동코일(25) 및 고정접점판(26)을 각각 소요 두께치수를 갖는 별도의 금속판재로 타발하고, 절곡가공하여 구성한다. 전원측단자(24), 구동코일(25), 고정접점판(26)의 판 두께나 폭치수를 독립하여 자유롭게 설정할 수 있으므로 구동코일(25)의 링폭을 크게 함으로서 두께를 크게 하지 않아도 큰 통전단면적을 확보할 수 있다.An object of the present invention is to provide a drive coil between a stationary contact plate and a power supply side terminal, and to reduce the width of the drive coil in the width direction. The solution means includes a plurality of magnetic materials between the power supply side terminal 24, the drive coil 25, the fixed contactor 21 having the fixed contact plate 26, and the side plate 29 of the insulation agent in the arc extinguishing chamber of the case. The arc extinguishing device 22 which has the grid board 30 up and down multistage is arrange | positioned. The power supply side terminal 24, the drive coil 25, and the fixed contact plate 26 are each punched out of a separate metal sheet having a required thickness dimension and are bent. Since the thickness and width of the power supply terminal 24, the drive coil 25, and the fixed contact plate 26 can be freely set independently, the ring width of the drive coil 25 is increased to increase the conduction area without increasing the thickness. It can be secured.
