Abstract: A connector housing for an air bag connector and a method for contacting an air bag connector. A connector housing having at least two sections is provided with locking elements for a pre-lock-in position and a final lock-in position. In the pre-lock-in position, both sections of the housing are arranged apart from one another and the pre-lock-in position is localized by means of a spacer to maintain the pre-lock-in position maintain at a predetermined distance so that electric conductors can be introduced into the connector housing. The spacer ensures that the connector housing is not inadvertently pressed from the pre-lock-in position to the final lock-in position. The connector housing can be pressed together for an insulation-piercing contact in the connector housing, and locked in the final lock-in position. The connector housing is furthermore provided with a belt arrangement, with the spacer being of a one-piece design with one of the elements of the belt arrangement.

The contact chamber has a square cross section preceded by a sealing chamber of round cross section. An inbound contact element encounters a keying element between the sealing and contact chambers for proper alignment. The frontal edges of the keying elements are slanted to form a blunt cone-shaped funnel for aligning the contact element.
Abstract: An electrical contact element having a contact base, and with a cover-spring provided on and affixed to the contact base. The contact element forms a one-piece punched/bent component of sheet metal with a connector part formed by a crimped member, and with a tubular contact base extending forwardly therefrom. The cover-spring is designed in two pieces, each cover-spring piece having a cover-spring base part. Those base parts are affixed to the contact base opposite each other in relation to the longitudinal midaxis of the contact base.
Abstract: An electrical switching arrangement for an electric contacting system of an airbag having a short circuit bridge arrangement in a plug, which includes a counter-contact casing and a contact sleeve casing of plastic. In the two casings, there are provided chambers in which are seated connectors connected to electric lines. The casings of the plug are hinged with one another, and a short circuit bridge is provided, in each case, between adjacent contacts in such a way that on opening of the plug, the adjacent contacts are short-circuited first before the connectors of the plug are separated. The contact sleeve casing is constructed substantially in slab form and includes a surrounding casing and an inner casing. The inner casing includes side walls and two front walls, as well as a cover wall and a bottom wall.

Abstract: A process and apparatus for applying sealing glands to electric lines. The sealing glands are positioned in guide sleeve, and the electric line is held by centering jaws so that the electric line and the sealing gland are in alignment with each other. Clamping jaws secure the electric line a short distance behind the end of the line, which is secured with very little play in the centering jaws. A ram is inserted into the guide sleeve, and moves the guide sleeve and the sealing gland toward the electric line until the sealing gland strikes the centering jaws. The centering jaw mechanism then moves toward the clamping jaw mechanism, and the sealing gland is pushed over the electric line.
