Abstract
A plug for gas generators of air bag impact protection systems has current paths formed by sheet metal strips and an inductance coil in one of both interrupted current paths that form two poles. One of the current paths is U-shaped; its branch opposite the counter-current path (4) is interrupted to form two inner poles (1, 2) and acts as a mechanical support for the inductance coil (5) that electrically bridges the interruption, and the other branch (3), located next to the counter-current path (4), forms together with the counter-current patch (4) plug pins (6, 7) that extend outwards. The plug pins (6, 7) are formed by bending the T-or forked-shaped ends of the current paths (3, 4). The inductance coil (5) is arranged in a housing and is provided with electric connections that can be directly connected to the inner poles (1, 2). In order to manufacture this plug, a preform is first cut out of a sheet metal web. The poles and current paths are repeated and held away from each other in the preform, then are embedded in a common substrate and the inductance coil (5) is mechanically and electrically connected to its support (1, 2).
