The breaker apparatus is disclosed which comprises a projecting wall standing upright from the base of a breaker body; a pair of plate-shaped fixed electrodes laid on the front and back surfaces of the projecting wall; a recessed plug to be fitted on the projecting wall; a U-shaped movable electrode to be stored in the plug for bringing the both fixed electrodes into conduction by clamping the projecting wall on the front and back surfaces thereof; a fuse storage section for storing a fuse connected to one of the fixed electrodes in the surrounding wall standing upright from the base in parallel with the projecting wall; a cover for covering the opening of the fuse storage section and being fittable to the surrounding wall; an engaging surface formed on the plug and facing in the fitting direction of the plug; and a cover motion stopper provided on the cover for engaging with the engaging surface of the plug with the plug fitted to the projecting wall.

Breaker apparatus

A breaker apparatus comprises: a breaker switch including a pair of fixed electrodes standing upright on the breaker body, a plug detachably mounted on the breaker body, and a movable electrode provided on the plug for disconnecting and connecting between both fixed electrodes by being pulled out or pushed in to the both fixed electrodes; and a fuse mounted in parallel with the breaker switch, characterized in that a locking lever is pivotably mounted on one of the breaker body and the plug and the locking lever is pivoted to the locking position where the plug is locked in the fitted state, in that the breaker body is provided with a micro switch having a swinging strip for detecting whether or not the locking lever is pivoted to the locking position so that the micro switch is activated when the tip of the locking lever pivots along the length of the swinging strip and presses the swinging strip on the way to activate the micro switch, and in that the tip of the locking lever is formed so that the length is maximum at the rear edge that trails when the locking lever is pivoted toward the locking position and decreases gradually toward the leading edge.

In the breaker device, a pair of stationary electrodes are arranged on the front and the rear side of the protruding wall , that is, the pair of stationary electrodes are collected at one place. Therefore, the pair of stationary electrodes have a space round both the stationary electrodes in common. Accordingly, the size of the breaker device can be reduced. Further, when the radius of curvature of the continuity section connecting the pinching pieces is made large, concentration of stress in the movable electrode can be relieved. Therefore, the pinching forces of both the pinching pieces can be increased. Accordingly, it is possible to ensure a sufficiently high contact pressure between the movable electrode and the stationary electrodes

Breaker device

Shield connector

A shield connector is configured in a manner that a flange to be fixed to a partner-side wall is made conductive, and the shield layer of a shield wire is electrically connected to the conductive sleeve which is integrated with the flange. Thus, the configuration for electrically connecting the shield layer and the partner-side wall is simplified and the number of parts of the shield connector can be reduced.
