Abstract

Abstract An electric control device or contactor devoid of a mounting bracket and adapted for mounting on a mounting panel and comprising an electrically insulating housing, a stationary contact structure and a movable contact structure within the housing; the device also comprising electromagnetic means for actuating the movable contact carrier structure between opened and closed positions with respect to the stationary contact structure, the movable contact carrier structure also comprising a magnetic coil, an armature, and a magnet; the housing having walls forming an axial opening through which the movable contract structure is inserted or withdrawn from the housing; and means for detachably mounting the assembly of the movable contact structure, armature, the coil, and the magnet in an operative position within the housing and said means including a detachable clip mounted on two opposite housing walls and including a retaining pin extending through an opening in the magnet which pin includes opposite end portions seated within corresponding notches in the housing and retained therein by the clip. The stationary contact structure includes a conducting strap having a downturned portion which strap includes opposite end notches for engagement with corresponding projections in the housing to prevent longitudinal movement of the strap and the downturned portion includes an aperture adapted to receive corresponding projection of the housing, whereby the strap is detachably seated in place on the housing.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 190 words
An electric control device for use on a mounting panel comprising an electrically insulating housing, the housing comprising a stationary contact structure, a movable contact carrier structure within the housing and movable between open and closed positions relative to the stationary contact structure, biasing means for holding the movable contact carrier structure in one of the positions, electromagnetic means for actuating the contact carrier structure to the other of the positions and comprising a magnetic coil, an armature, and a magnet, the magnetic coil being mounted on one of the movable contact carrier structure and the housing, the armature being mounted on the other of the movable contact carrier structure and the housing, the housing comprising walls forming an aCcess opening through which the movable contact carrier structure, the armature, the coil, and the magnet are inserted into the housing, at least one housing wall comprising an enlarged projection, and means for detachably mounting the assembly of the movable contact carrier structure, the armature, the coil and the magnet intact within the housing and including fastening means comprising at least one detachable clip having a portion engaging a corresponding projection.
Claim 2
Dependent Claim 190 words
An electric control device for use on a mounting panel comprising an electrically insulating housing, the housing comprising a stationary contact structure, a movable contact carrier structure within the housing and movable between open and closed positions relative to the stationary contact structure, biasing means for holding the movable contact carrier structure in one of the positions, electromagnetic means for actuating the contact carrier structure to the other of the positions and comprising a magnetic coil, an armature, and a magnet, the magnetic coil being mounted on one of the movable contact carrier structure and the housing, the armature being mounted on the other of the movable contact carrier structure and the housing, the housing comprising walls forming an aCcess opening through which the movable contact carrier structure, the armature, the coil, and the magnet are inserted into the housing, at least one housing wall comprising an enlarged projection, and means for detachably mounting the assembly of the movable contact carrier structure, the armature, the coil and the magnet intact within the housing and including fastening means comprising at least one detachable clip having a portion engaging a corresponding projection.
Claim 3
Dependent Claim 26 words
