Abstract

Ein pyrotechnischer Stromtrenner (1) zum Durchtrennen eines Leiters (2) mittels eines Trennkolbens (8) ist aus einem Unterteil (6) und einem Oberteil (5), in dem ein Zünder (7) angeordnet ist, zusammengesetzt. Der Leiter (2) ist zwischen Unterteil (6) und Oberteil (5) eingelegt und weist Löcher (4a, 4b) auf. Erfindungsgemäß erstrecken sich die Schrauben (13a, 13b), die Unterteil (6) und Oberteil (5) miteinander verbinden, durch die Löcher (4a, 4b), sodass keine zusätzlichen Elemente notwendig sind, um den Leiter (2) in Längsrichtung zu fixieren. Die Schrauben (13a, 13b) dienen gleichzeitig zur Versteifung des Gehäuses. Wenn sich z.B. eine Auffangkammer für den Trennkolben (8) bzw. die von ihm ausgestanzte Platine (12) vom Leiter (2) weg verjüngt, entsteht beim Abbremsen von Platine (12) und Trennkolben (8) ein Biegemoment, das von den Schrauben (13a, 13b) aufgenommen wird.
