Abstract (en)
[origin: EP0319478A2] In a very small hinged-armature relay of the printed-circuit board relay type, with a dual-in-line connector layout, which relay must be designed for a very high number of operations, the problem exists of designing the armature return spring such that it can withstand the number of operations without any risk of fracture. This problem is solved in the case of the present relay such that the leaf spring, which is connected in a positively locking manner to the limbs of the U-shaped armature (13), and which acts as a return spring, runs approximately parallel to the said limbs and is connected in a force-fitting manner to the coil body (10) forming the relay structure, in contrast to the normal fixing on the corresponding limbs of the E-shaped magnetic yoke (12). In this way, the spring can have a length which is at least equal to the length of the limbs of the armature. In order to simplify production and assembly, the leaf springs of the individual limbs are connected via a lateral web to a single-piece, H-shaped spring (14). <IMAGE>
