Abstract

Un dispositif de protection de ligne pour circuit de communications assure une protection contre les surtensions et les surintensités. La protection contre les surtensions est assurée par l'intermédiaire d'un parafoudre qui interpose un éclateur entre la ligne et la terre. Pour la protection contre les surintensités, un élément fusible peut être fondu par une bobine thermique, ce qui provoque l'entrée en contact d'une cuvette conductrice avec une plaque conductrice connectée à une broche de ligne en établissant ainsi une dérivation métallique directe à la terre. L'ensemble de la bobine thermique, les broches de ligne et les plaques de contact associées aux broches de ligne sont montées sur une embase secondaire diélectrique, supportée à son tour par l'embase principale du protecteur. Les extrémités de la bobine thermique sont soudées aux plaques de contact et les broches de ligne sont matées sur les plaques de contact, ce qui élimine toute connexion par contact de butée génératrice de bruit dans le circuit de ligne.
