A hybrid connector with electric plug-in connections and fiber-optic demountable connections for an electronic built-in unit. The hybrid connector has a female connector and an angular male connector strip having long side walls. The female connector has a cover cap with module chambers for holding electric receptacle modules and fiber-optic modules. Electrooptical transducers having connecting leads with ends defining solder terminals are assigned to the fiber-optic connectors of the fiber-optic modules. The electrooptical transducers are disposed in a base of the angular male connector strip. The electrooptical transducers are aligned in a row parallel to the long side walls on a side on which solder terminals of the male connector strip are located. In this manner, the length of the connecting leads including the solder terminals is as small as possible.

Hybrid connector

A contact member includes a double insulation displacement terminal with two parallel insulation displacement terminal contact limbs which are connected to one another through a central part. The central part is provided with apertures and cutouts which are matched to the geometry of plug-in blade contacts.

A firing-cap plug connector for a collision safety device, in particular in vehicles, includes a plug having a housing with a lower housing component and an upper housing component. A contact chamber is provided for the connection of a clamping contact to connecting lines disposed perpendicularly thereto, through the use of insulation piercing devices. The contact chamber is surrounded by a flow duct configuration which is completely filled with an elastic sealing compound in a pressurized manner from the outside of the housing through an injection opening, in order to seal the contact chamber at a dividing gap between the upper housing component and the lower housing component.

A top spring of a bush contact encloses a base spring like an enclosing box. The top spring is a stamped and bent part with a production-dictated longitudinal slit in the top wall (extending in a plug-in direction). To form a stable, closed box form of the top spring, the slit top wall parts are provided with a connecting tab, respectively at either end of the longitudinal slit. The connecting tab is joined to the respectively opposite top wall part by form lock and/or by force lock.

In order to provide a simple connection between a shield housing and a strip body, the shield housing has resilient side parts with spring arms being initially bent inwards and then outwards and being pushed over lead-in and sliding inclines on the strip body and automatically latched on an insertion side or front of the strip body. Those sections of the spring arms which are bent outwards form contact elements for the shield housing to make contact on a mounting panel. The invention is suitable for motor vehicle filter plug connectors.

Filter plug connector having a shield housing

In order to provide a simple connection between a shield housing and a strip body, the shield housing, which has resilient side parts with spring arms being bent inwards, is pushed over lead-in and sliding inclines on the strip body and automatically latches on an insertion side or front thereof. The spring arms of each side part, which are located alongside one another, alternately form contact elements providing contact between the shield housing and a mounting panel and sliding and latching elements for connecting the shield housing to the strip body. The invention is suitable for motor vehicle filter plug connectors.

A two-legged contact spring with a spring base, at least one contact leg and a U-shaped bend is provided as a short-circuit bridge for the connection of two contact elements. The contact leg is freely yielding and has a projection which contactingly rests directly at a transitional region of the contact element. Therefore, the spring work is carried out exclusively by the short-circuit bridge. The spring form and position of the contact point ensures an optimal spring action at low operating forces.

A contact element has an improved press in zone which is formed by two leg members extending substantially parallel to one another with an interconnecting web. The improvement is that the web is broken up into portions with adjacent portions having curvatures that extend in opposite directions to increase the strength of the press in zone and provides an optimally uniform, symmetrical pressure distribution between a bore wall and the press in zone of the contact element when the press in zone is plugged into a bore of a printed circuit board.

A sliding switch, for example a microswitch, comprises a membrane between an actuating member and a contact chamber, an intermediate sheet provided between the membrane and the actuating member has three tongues of which a middle tongue simultaneously acts on the first two ends of two double-arm contact bridges disposed parallel to one another, so that a double transfer with a close contact chamber is realized.
