Abstract

Die Erfindung beschreibt einen elektromagnetischen Auslöser (1), mit einem feststehenden Magnetkern und einem beweglichen Magnetanker, die in einem zylindrischen, rohrförmigen Spulenkörper (2) mit einer Mittelachse (3) angeordnet sind, mit einer um den Spulenkörper (2) gewickelten Spule (4) , die zwei Endteile (5, 6) aufweist und an jedem Endteil (5, 6) ein Anschlussstück (7, 8). Die Anschlussstücke (7, 8) sind spiegelsymmetrisch bezogen auf eine gedachte Spiegelebene (9) angeordnet und ausgeführt, wobei die Spiegelebene (9) in der Mitte zwischen den beiden Endteilen (5, 6) senkrecht zur Mittelachse (3) der Spule (4) verläuft, und jedes Anschlussstück (7, 8) entfernt sich in einer zur Mittelachse (3) parallelen Richtung von den Wicklungen der Spule (4) entfernt.

The invention relates to an electromagnetic release (1) comprising a fixed magnetic core and a movable armature arranged in a cylindrical, tubular bobbin (2) with a central axis (3), with a coil (4) wound around the bobbin (2) ), which has two end parts (5, 6) and at each end part (5, 6) a connection piece (7, 8). The connecting pieces (7, 8) are arranged and executed mirror-symmetrically with respect to an imaginary mirror plane (9), wherein the mirror plane (9) in the middle between the two end parts (5, 6) perpendicular to the central axis (3) of the coil (4) runs, and each connector (7, 8) moves away in a direction parallel to the central axis (3) direction of the windings of the coil (4).
