Abstract:
A motor vehicle starter contactor, comprising: a casing comprising a hollow annular cylindrical armature having an open front end and a hollow end cap secured on the front end of the armature, the end cap having a base portion and a lateral skirt portion extending from the base portion and defining within the end cap an internal chamber open towards the interior of the armature, the casing defining a contactor axis; a pair of fixed power contact terminals carried by the base portion of the end cap; an axially movable contact within the internal chamber, a control rod extending axially in the internal chamber and carrying the movable contact; a fixed core in the form of a disc mounted radially in the front end of the armature, the fixed core having a central hole mounting the control rod for axial displacement of the control rod therein, wherein the control rod can displace the movable contact into and out of cooperation with the fixed power contact terminals; a movable core, with the armature mounting the movable core within the armature for axial displacement of the movable core wherein the movable core acts on the control rod to effect said axial displacement of the control rod; a solenoid winding mounted in the armature for actuating the movable core in said axial displacement thereof; and an electronic control circuit for the contactor, the circuit comprising a disc-shaped support having a central through hole, the support being located within the end cap in an axial position between the fixed core and the movable contact, the control circuit further including electronic components carried by the support, wherein the contactor further includes a housing disposed within the end cap in a location in said internal chamber between the fixed core and the movable contact, the electronic control circuit being disposed within the housing wherein to be protected by the housing; and the contactor further including electrical connection means carried by the housing, wherein the housing has a transverse front wall and a cylindrical side wall extending from the front wall to define a generally cylindrical housing chamber within the housing, the electronic control circuit being mounted within the housing chamber, and the housing chamber having an open rear end adjacent to the front face of the fixed core.
