Electromagnetic relay
First Claim
1. Electromagnetic relay with the following features:
- a coil body (1) forms a coil tube (11) with two flanges (12, 13) and carries a winding (2) on the coil tube (11);
a first of the two flanges (12) forms a switch space (14) with a base side (15) parallel to the coil axis;
within the coil tube (11) there is arranged an axial core (16) which forms a pole face toward the switch space (14) arid is connected to an L-shaped yoke (20) in the region of the second flange (13);
with its free end, the yoke (20) forms, in the region of the switch space, a bearing edge (21), perpendicular to the base side (15), for a plate-shaped armature (22) which forms a working air gap with the pole face of the core (16);
at least one fixed contact support (3) carrying a first fixed contact is secured in the coil body in the vicinity of the moving end of the armature; and
a contact spring (23;
33) formed from flat strip material is connected to the armature (22), carries a moving contact (25) at one free end (23a) in the region of the moving end of the armature and is connected to a contact spring connecting pin (5) of the relay via a connecting portion (23c;
33c), characterised in that the contact spring connecting pin (5) and the at least one fixed contact support (3, 4) consist of drawn or rolled wire and are embedded in the coil body (1).

Abstract
The inventive relay has a base body in the form of a coil body (1), the base body supporting a core (16), a yoke (20), an armature (22) and a contact spring (23) which is connected to the armature. Fixed contact supports (34) and a contact spring connection pin (5) which consist of semi-finished wire with a preferably rectangular or square cross-section are embedded in a flange (12) of the coil body (1). The inventive electromagnetic relay is therefore very simple to produce. There is no wasted material, no punching tools are needed for the contact connection parts and since no particles of plastic are abraded by insertion, there is no risk of this impairing the quality of the relay.
