Motor vehicle starter contactor incorporating an auxiliary control relay
First Claim
1. A motor vehicle starter contactor, comprising:
- a casing comprising a 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 contacts carried by the base portion of the end cap;
an axially movable contactor contact within the internal chamber;
a control rod extending axially in the internal chamber and carrying the movable contactor contact;
a fixed contactor core in the form of a disc mounted radially in the front end of the armature, the fixed contactor core having a central hole mounting the control rod for axial displacement of the control rod, displacement of the control rod carrying the movable contactor contact into and out of engagement with the fixed power contacts;
a movable contactor core mounted to effect said axial displacement of the control rod;
a contactor coil mounted in the armature for actuating the axial displacement of the movable contactor core;
an auxiliary relay, comprising an auxiliary relay coil, a movable relay core carrying an auxiliary moveable contact, and a contact carrier plate carrying an auxiliary fixed contact, the auxiliary relay contacts controlling current to effect the axial displacement of the control rod, the movable relay core being symmetrically disposed along the contactor axis;
the auxiliary relay coil, contact carrier plate being mounted, in that order in rearward axial succession, between the movable contactor contact and the fixed contactor core.

Abstract
A contactor for a motor vehicle starter comprises a contactor coil, a movable contactor core actuated by a control rod, and a fixed contactor core. It also has an electromagnetic auxiliary control relay which includes a movable relay core carrying a movable contact ring which is arranged for cooperation with at least one pair of fixed relay contacts, carried by a fixed annular contact carrier plate. The relay coil, the contact carrier plate, and the movable contact ring are arranged in axial succession, in that order towards the front of the contactor, and are disposed between the movable contact of the contactor and the fixed core, so that the relay and the contactor are closed in the same, forward, direction.

15. A motor vehicle starter contactor, comprising:
-
a casing, a fixed power contact in an end cap of the casing, a primary movable contact for making a circuit with the fixed power contact, a control rod extending on an axis of the contactor and carrying the primary movable contact; and an auxiliary relay, comprising an auxiliary relay coil, an auxiliary relay core carrying a secondary moveable contact, and a contact carrier plate carrying a secondary fixed contact;
the secondary moveable and secondary fixed contacts controlling current to effect axial displacement of the control rod to make the contact between the fixed power contact and the primary movable contact;the auxiliary relay core being symmetrically disposed about the contactor axis, the contact carrier plate being mounted between the auxiliary relay coil and a fixed contactor core. - View Dependent Claims (16, 17, 18, 19, 20)
