Patent

CA 2309134

The inventive relay has a base body in the form of a coil body (1), said 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 (3, 4) 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.

L'invention concerne un relais possédant une armature de bobine (1) comme corps de base. Cette armature de bobine (1) porte un noyau (16), une culasse (20), un induit (22) ainsi qu'une lamelle de contact (23) reliée à l'induit. Des supports (3, 4) de contacts solides et une broche de connexion (5) de lamelle de contact, constitués d'un demi-produit fil de section rectangulaire ou carrée, sont intégrés dans un flasque (12) de l'armature de bobine (1). On obtient ainsi un mode de production très simple ne générant pas de chutes de matériau et ne nécessitant pas d'outils à estamper à froid. De plus, il n'y a aucun éclat de matière plastique lors de l'insertion ce qui pourrait nuire à la qualité du relais.
