Abstract

L'invention concerne un éclateur à cornes miniaturisé comprenant une chambre de désionisation intégrée, composé d'un boîtier en matière isolante en plusieurs parties comme corps de support et de réception pour les électrodes à cornes et la chambre de désionisation, les électrodes à cornes présentant une forme asymétrique comprenant une électrode longue ou une électrode plus courte. La chambre de désionisation est réalisée sous la forme d'une partie de chambre de désionisation pouvant être intégrée dans le corps de support et de réception, laquelle reçoit une pluralité de tôles d'extinction et comprend des canaux de passage. Selon l'invention, les électrodes à cornes sont munies d'un dépôt métallique dans au moins la zone de course d'un arc électrique, l'électrode la plus courte étant réalisée comme électrode à cornes à crochet s'étendant jusqu'à la partie de chambre de désionisation et étant, espacée sur le côté de sortie de canaux de passage, au moins partiellement couverte par une paroi d'impact métallique, la paroi d'impact pouvant être connectée simultanément au boîtier en matière isolante, le renforçant mécaniquement.
