Abstract

Beschrieben und dargestellt ist ein Überspannungsschutzelement (1) zur Ableitung von transienten Überspannungen, mit zwei Elektroden (2, 3), einer zwischen den Elektroden (2, 3) wirksamen Luft-Durchschlag-Funkenstrecke (4) und einem die Elektroden (2, 3) aufnehmenden Gehäuse (5), wobei jede Elektrode (2, 3) einen Anschlußschenkel (6, 7) und ein unter einem Winkel zu dem zugehörigen Anschlußschenkel (6, 7) verlaufendes Funkenhorn (8, 9) aufweist und zwischen den Funkenhörnern (8, 9) der beiden - mit Abstand zueinander angeordneten - Elektroden (2, 3) die Luft-Durchschlag-Funkenstrecke (4) ausgebildet ist.An overvoltage protection element (1) for discharge is described and shown of transient overvoltages, with two electrodes (2, 3), one between the Electrodes (2, 3) effective air breakdown spark gap (4) and one Electrode (2, 3) housing (5), each electrode (2, 3) has a connecting leg (6, 7) and one at an angle to the associated connecting leg (6, 7) extending spark horn (8, 9) and between the spark horns (8, 9) of the two electrodes (2, 3) arranged at a distance from one another the air breakdown spark gap (4) is formed.

Erfindungsgemäß ist das Überspannungsschutzverhalten verbessert, und zwar dadurch, daß die Luft-Durchschlag-Funkenstrecke (4) abgebogen und/oder abgewinkelt ausgebildet ist und daß die Funkenhörner (8, 9) jeweils einen etwa rechtwinklig zum Anschlußschenkel (6, 7) verlaufenden geraden unteren Bereich und einen sich an den geraden Bereich anschließenden bogenförmigen oberen Bereich aufweisen.According to the invention, the surge protection behavior is improved, specifically by that the air breakdown spark gap (4) is bent and / or angled is formed and that the spark horns (8, 9) each have an approximately right angle to the connecting leg (6, 7) extending straight lower area and one have an arcuate upper region adjoining the straight region.
