Abstract
A relay includes a coil body having a pair of flanges, a U-shaped core yoke, a flat armature, and at least one cooperating contact element anchored in the coil body. An angled leaf spring is secured to the armature, the leaf spring having an extension forming a contact spring and being simultaneously secured to said yoke by a U-shaped adjustment piece which serves as a bearing spring for the armature. All terminal elements are formed as tabs and are conducted downwardly out of the relay in a common plane perpendicular to the plane of integration of the relay so that an extremely narrow structure is provided.
Claims32
An electromagnetic relay, comprising:
- a coil winding applied to a coil body having a coil axis extending parallel to a plane of integration of said relay;
- two coil flanges having said coil body therebetween;
- a U-shaped flat core yoke having a principle plane extending perpendicular to said plane of integration, a portion of said yoke being disposed above said coil winding,
- a first leg of said core yoke extending through said coil body in an axial direction as a core,
- a second leg of said core yoke proceeding outside of said coil as a yoke;
- a plate-shaped armature seated at a free end of said yoke and forming a working air gap with a free end of said core;
- an angled leaf spring secured to said yoke and to said armature, said leaf spring having a portion extending beyond a free armature end to form a contact spring;
- a first terminal element connected in electrically conductive fashion to said leaf spring;
- second and third coil terminal elements;
- plug-in channels in said coil body for fastening said second and third terminal elements;
- at least one cooperating contact element provided in said coil body;
- and
- all of said terminal elements being conducted in one plane toward outside said relay perpendicularly to a connecting plane of said relay.
An electromagnetic relay, comprising:
- a coil member including a winding between first and second generally parallel flanges;
- a U-shaped flat core yoke having first and second generally parallel legs, said first leg extending through said winding to form a core of said coil member, said second leg extending parallel to said winding outside said coil member to form a yoke;
- an adjustment piece having first and second portions at an angle relative to one another, said first portion being affixed to said yoke;
- a leaf spring having first and second legs at approximately a right angle to one another, said first leg of said leaf spring being affixed to said second portion of said adjustment piece;
- a flat armature carried on said second leg of said leaf spring and seated at a free end of said yoke, said armature forming a working air gap with a free end of said core;
- cooperating contacts movable into and out of contact by movement of said armature;
- and
- a plurality of terminals extending from said relay in a single plane, one of said terminals being electrically connected to one of said cooperating contacts, a pair of said terminals being electrically connected to said winding, said terminals lying generally in the same plane as said core yoke so that a narrow relay structure results.
