Electromagnetic relay structure

In an electromagnetic relay having a coil holder body and an armature mounted inside said body, said coil holder being composed of two substantially tightly interfitting parts, the improvement wherein said two parts of said coil holder body essentially consist of two identically constructed contact holders.

In an electromagnetic relay having a coil holder body and an armature mounted inside said body, said coil holder being composed of two substantially tightly interfitting parts, the improvement wherein said two parts of said coil holder body essentially consist of two identically constructed contact holders and wherein one half of a further coil flange is formed in the middle of said contact holders and contains a contact terminal pin to which a twin-bladed contact blade is centrally fixed attached.

In an electromagnetic relay, having a coil holder body and an armature mounted inside side body, said coil holder being composed of two substantially tightly interfitting parts, the improvement wherein said two parts of said coil holder body essentially consist of two identically constructed contact holders and including a retaining spring and a central flange on said coiil holder, wherein recesses in said central flange are covered by said retaining spring.

An electromagnetic relay according to claiim 54, including coil terminals having upper ends mechanically connected to a conductor plate and electrically to a circuit on the plate.

In an electromagnetic relay, having a coil holder body and an armature mounted inside side body, said coil holder being composed of two substantially tightly interfitting parts, the improvement wherein said two parts of said coil holder body essentially consist of two identically constructed contact holders and a U-shaped retaining spring being provided in said contact holders and permanent magnets being provided in said holders, said spring having two shanks forming poleshoes which touch the outer faces of said permanent magnets and also including at least one short circuiting ring provided on at least one of said poleshoes.

In an electromagnetic relay including a coil holder body and an armature located therein, said coil holder being of undivided integral construction, the improvement comprising that portions adapted to serve as contact holders and containing therein fixed contacts as well as contact and winding terminals are moulded to flanges of said integral coil holder and wherein an opening which serves as a socket for a pivot pin is formed in the middle of said coil holder and wherein facing the same inside said coil holder there is a pivot pin bearing which forms a bearing shoulder with a funnel-shaped entry opening.

An electromagnetic relay including a coil holder body and an armature located therein, said coil holder being of undivided integral construction, the improvement wherein portions adapted to serve as contact holders and containing therein fixed contacts as well as contact and winding terminals are molded to flanges of said integral coil holder and including a T-shaped ferromagnetic armature provided on its Tee-arms with a knife edge and armature wings, said knife edge being urged by a U-shaped armature retaining spring having free ends engaging corners in the base of a U-shaped yoke into V-shaped notch punched centrally into the base of said yoke including two adjusting springs, each having one side attached to the base of said yoke with the other sides of said springs being so flexed by adjusting screws that the armature wings underneath are optionally subjected to the different spring thrusts needed to hold the armature in a stable position on one or both sides so that desired operated and/or release response thresholds may be obtained.

In an electromagnetic relay including a coil holder body and an armature located therein, said coil holder being of undivided integral construction, the improvement comprising that portions adapted to serve as contact holders and containing therein fixed contacts as well as contact and winding terminals are moulded to flanges of said integral coil holder and wherein fixed contacts in the contact holder part of said coil holder are arranged to function as poleshoes, said fixed contacts being correspondingly made of ferromagnetic material and arranged to make contact on one side with magnets with the other side thereof facing an armature contact being provided with a plate of contact material which also functions as a magnetic separator.

In an electromagnetic relay having a coil holder body and an armature inside said body, said coil holder body being composed ot two substantially tightly interfitting parts, the improvement being wherein said two parts of said coil holder body essentially consist of two identically constructed contact holders, and wherein a U-shaped retaining spring of ferromagnetic material is provided in said two identical contact holder parts, said spring retaining permanent magnets in said holders, said U-shaped spring having two shanks forming pole shoes mechanically contacting outer pole faces of said permanent magnets, another retaining spring having off-angled ends which engage shoulders in said contact holders and a further retaining spring similarly disposed as the symmetrical mirror image on the opposite side of the relay.

In an electromagnetic relay including a coil holder body and an armature located therein, said coil holder being of undivided integral construction, the improvement being wherein said coil holder has flanges therein and wherein portions adapted to serve as contact holders and containing therein fixed contacts as well as contact and winding terminals are molded to said flanges of said integral coil holder, and wherein said armature is a T-shaped ferromagnetic element provided on the arms of the "T" with a knife edge and armature wings, and wherein a U-shaped armature retaining spring and a U-shaped yoke is included, said spring having free ends engaging corners in the base of the said U-shaped yoke, said U-shaped yoke having a V-shaped notch positioned centrally in the base of said yoke, said knife being urged by said spring into said V-shaped notch.
