Abstract

Bei einem elektrischen Schaltgerät, insbesondere einem Relais, umfassend ein Gehäuse (10), einen in dem Gehäuse (10) angeordneten, eine Spule (20) tragenden Magnetwinkel (30), einen an dem Magnetwinkel (30) angeordneten Kern (32) der Spule (20), wenigstens zwei in dem Gehäuse (10) angeordnete Anschlußklemmen (35,50), deren eine mit dem Magnetwinkel (30) verbunden ist, und einen an dem Magnetwinkel federnd angeordneten Anker (42), durch dessen Betätigung ein Kontakt zwischen den wenigstens zwei Anschlußklemmen (35,50) herstellbar ist, und bei einem Verfahren zur Herstellung eines Magnetwinkels (30) für ein solches ist vorgesehen, daß der Magnetwinkel (30), der Kern (32) und die mit dem Magnetwinkel verbundene wenigstens eine Anschlußklemme (35) ein gebogenes, einstückiges Stanzteil sind, bei dem der Kern (32) im ungebogenen Zustand als eine in dem Magnetwinkel liegende separat biegbare Zunge ausgebildet ist.

Figure 00000001
In the case of an electrical switching device, in particular a relay, comprising a housing (10), a magnetic angle (30) arranged in the housing (10) and carrying a coil (20), a core (32) of the coil arranged on the magnetic angle (30) (20), at least two connecting terminals (35, 50) arranged in the housing (10), one of which is connected to the magnetic bracket (30), and an armature (42) which is resiliently arranged on the magnetic bracket, and by its actuation a contact between the at least two connecting terminals (35, 50) can be produced, and in a method for producing a magnetic angle (30) for such a provision, the magnetic angle (30), the core (32) and the at least one connecting terminal connected to the magnetic angle ( 35) are a bent, one-piece stamped part, in which the core (32) in the unbent state is designed as a separately bendable tongue lying in the magnetic angle.
