Abstract
A relay having a basic body with a bearing pin secured in its wall or base which protrudes perpendicularly from the wall. A contact spring made of strip material is taken partly around the bearer pin with a securing section in the form or a clamping sleeve. Besides a spring shank it forms on the other side of the securing section a prestressing shank supported on a supporting component, preferably a coil flange and thus prestresses the spring shank in its position of rest. The contact spring can also be fitted in cramped and poorly accessible positions, e.g. between the coil and the armature and given a predetermined prestress without its having to be soldered to the bearer pin or subsequently adjusted.
Claims7
An electromagnetic relay, comprising:
- a base body having a wall,
- an armature;
- a terminal pin having an axis;
- at least one carrier pin anchored in said wall of said base body and extending perpendicularly from said wall, and
- at least one contact spring which comprises a strip material, which is partly wrapped around said at least one carrier pin and secured on said at least one carrier pin by a securing section, and has a contacting spring shank which can be switched over by said armature about the axis of said terminal post between a position of rest and a working position,
- a coil former to which said base body is firmly joined in front of one end face of which said armature of flat design is arranged,
- said carrier pin being arranged with said at least one contact spring between said armature and said coil former,
- said securing section of said at least one contact spring being a clamp sleeve which is plugged onto said at least one carrier pin in a force-closed fashion, and
- a prestressing shank extending beyond said clamp sleeve as a continuation which is supported on said coil former and prestresses said spring shank into said position of rest via said at least one carrier pin as a lever axis.
