Abstract

A pyrotechnic ignition pill with a housing, an ignition pill charge housed in the housing, at least two terminal contacts connected to the ignition charge, wherein the terminal contacts are guided out of the housing through a glass bushing, characterized in that the terminal contacts in the region of the ignition charge have a round cross-sectional profile and that the terminal contacts outside the housing have an angular cross-sectional profile.

First claim

What is claimed is:

1. Pyrotechnic ignition pill with
a housing,
an ignition charge housed in the housing,
at least two terminal contacts connected to the ignition charge,
wherein the terminal contacts are guided out of the housing through at least one glass bushing, wherein
the terminal contacts in the region of the ignition charge have a round cross-sectional profile and the terminal contacts outside the housing have an angular cross-sectional profile such that the terminal contacts with angular cross-sectional profile are adapted for connector geometries which are designed for angular connection pins.

2. Pyrotechnic ignition pill according to claim 1 , wherein
the terminal contacts are formed from round wires and are plastically deformed outside the housing.

3. Pyrotechnic ignition pill according to claim 1 , wherein the terminal contacts have a first contact spacing in the region of the glass bushing and have a second contact spacing outside the housing which is greater than the first contact spacing.

4. Pyrotechnic ignition pill according to claim 1 , wherein
the terminal contacts in the glass bushing run straight and parallel to one another and run at an angle to one another outside the glass bushing in a central section and run parallel to one another in an end section.

5. Pyrotechnic ignition pill according to claim 1 , wherein
the terminal contacts are guided through two glass bushings facing each other.

6. Pyrotechnic ignition pill according to claim 1 , wherein
the terminal contacts outside the glass bushing are bent facing away from one another.

7. Pyrotechnic ignition pill according to claim 6 , wherein
the bend begins at a distance of at least the radius of the terminal contact from the glass bushing.

8. Pyrotechnic ignition pill according to claim 1 , wherein
the glass bushing has a glass pill and a support ring, a cover of the housing is arranged on the support ring in a material bond, and the ignition charge is arranged in the interior of the cover.

9. Pyrotechnic ignition pill according to claim 1 , wherein
the terminal contacts are guided in a connector housing on the side of the glass bushing opposite the ignition charge.

10. Pyrotechnic ignition pill according to claim 9 , wherein
the connector housing is made of a plastic, in particular injection-moulded, and/or the terminal contacts are bent inside the connector housing.

11. Pyrotechnic ignition pill according to claim 9 , wherein
the connector housing is formed onto the support ring and the glass bushing.

12. Pyrotechnic ignition pill according to claim 1 , wherein
the angular cross-sectional profile is formed by two longitudinal edges running parallel to one another and two transverse edges opposing one another, wherein the transverse edges are formed in an arcuate shape, in particular in a convex arcuate shape.
