Electromagnetic relay with a parallel to the flat, elongated core arranged,

also flat anchor.

Patented in the German Empire on May 2, 1925.

The invention relates to an electromagnetic relay with a parallel to Flat, elongated core arranged anchor and aims, through the use of Walzmaterial and the simplest formation of core and anchor as well as the contact etch production of the relay cheaper. The aim is to easily replace the anchor without to have an unfavorable influence on the reliable contact-making, can be guaranteed. According to the invention the flat core or anchor has a cutting edge at the point of movement, which in a recess of the opposite part extends into it and by a spring clip is rotatably held together. At the free end of the anchor is an easily adjustable one Fastened bracket, which limits the anchor in the rest position and once in a known manner on the other hand as a driver for the contact springs.

43879J The drawing illustrates two embodiments of the anchor bearing, namely: Fig. Ι a side view of a relay, its cranked armature at the bearing point using «one? · = - spring clip against the core is pressed, Fig. 2 the relay according to Fig. Ι seen from horned, Fig. 3 the relay according to Fig. Ι seen from the front with the stroke limiter and driver bracket, Fig. 4 another embodiment of the anchor bearing in the side and rear view. The core is made in the simplest way from a flat piece of iron and is provided on the fastening side with a notch & in which the cutting edge c of the anchor d, which is also made of flat iron, is supported. According to the invention, ¹ ao core and armature are at the bearing point of: a spring clasp e encompassed and held together (Fig. 4), so that the desired mobility of the armature on the core is ensured. Another type of armature mounting on the core is shown in Figs. 1 and 2. Here the cutting edge c of the armature d is pressed against the core by a spring clip e, which is arranged between this and an angle /. This type of storage and the spring clip holding the core and the armature together at right angles prevents the armature from bouncing. It should also be emphasized that the otherwise usual lateral guides for the armature can be omitted due to the cutting edge bearing. At the free end of the armature a bracket / made of non-magnetic material is arranged in a manner known per se, which on the one hand limits the armature in the rest position and on the other hand serves as a driver for the contact springs g by attaching an insulating piece. As a result of the arrangement of specially designed recesses k in the driver h , the same driver can advantageously always be used for the usual contact set assemblies for this relay. 1 ^J AT I NTANSP R OCHE: ι.
