Drawer-type circuit interrupter
First Claim
1. A drawer-type circuit interrupter constructed with an interrupter body (2) having a first contact member (8, 35, 51) having an open-and-close contact portion (24, 34, 52), an open-and-close operation mechanism (6) for operating said first contact member (8, 35, 51) and at least one second contact member (14, 30, 45, 100, 105, 106, 108), and a mounting frame (1) having external line connect terminals (4, 33, 103, 107, 109), said circuit interrupter characterized in that the second contact member (14, 30, 45, 100, 105, 106, 108) is a movable-type provided with an open-and-close contact portion (21, 48) that is contactable with and separable from the first contact member (8, 35, 51) on one end thereof and a drawer contact portion (20, 31, 49) contactable with and separable from an external line connect terminal (4, 33, 103, 107, 109) on the other end thereof, and further in that when the interrupter body (2) is in a connected position the drawer contact portion (20, 31, 49) on the other end of said second contact member (14, 30, 45, 100, 105, 106, 108) contacts an external line connect terminal (4, 33, 103, 107, 109).

Abstract
A drawer-type circuit interrupter is constructed with a first contact member having an open-and-close contact member, an open-and-close operation mechanism for operating said first contact member, an interrupter main body having a second contact member and a mounting frame having the external line contact terminals, wherein the second contact member is a movable-type provided with an open-and-close contact portion that is contactable with and separable from the first contact member on the one end thereof and a drawer contact member that contacts with an external line contact terminal on the other end thereof, and a compression spring for urging the second contact member into a direction for contacting the external line contact terminal on the other end of the second contact member. When the interrupter body is in the connected position the drawer contact portion on the other end of said second contact member and said external line contact terminal are into contact. The second contacting member and the external line connecting terminal can be constituted to contact each other at a plurality of points, for example two, to improve contact and interruption performance.
