Abstract: The invention relates to a socket contact (1) including a back-up spring (3) and a base spring (2), the back-up spring (3) enclosing the base spring (2) in box-like manner with a first wall (11), a second wall (12), a third wall (13) and a divided fourth wall (14). The wall sections (14a, 14b) of the fourth divided wall (14) are connected to each other in positive fitting manner. On one wall section (14a), there are formed at least two connecting lugs (23) arranged in the front and rear portions of the wall section (14a) as seen in the direction of insertion of the socket contact (1). The other wall section (14b) is formed with a recess (24) for each connecting lug (23), and the connecting lugs (23) are passed through the recesses (24) and bent over. For increased stability, the two wall sections (14a, 14b) overlap over the full length of the back-up spring (3).

Abstract: The invention relates to a plug-in contact (10) configured as a single-piece and made from a metal strip, comprising a pin-shaped contact part (12) and a connecting part (16) for connecting an electric line (18). A guide part (14) is arranged between the contact part (12) and the connecting part (16). The guide part (14) is configured in the shape of a box with a triangular cross-section and a flat side of said guide part (14) is arranged at a distance parallel to the original level of the metal strip.

Abstract: A contact spring includes a bottom spring having a centrally disposed spring arm base formed by a rectangular frame. A connection part is formed onto one end of the spring arm base, for electrical conductors. Two spring arms are each formed onto broad sides of the spring arm base on the opposite end. The spring arms converge in a wedge-like manner toward a free end and after that widen into a plug-in funnel. The spring arms are each kept spaced apart in the region of the contact zone by respective indentations oriented toward one another and disposed on long edges. A detent sleeve surrounds the spring arm base and the spring arms formed thereon. An opening angle of the plug-in funnel, over its entire length, is &agr;≦30. The spring arms are shaped spherically in the vicinity of the contact zone and each form a respective contact dome.

Abstract: A connector is provided having a pin plug with a plurality of first socket contacts for connection to system wires. The connector also has a mated socket plug with a plurality of second socket contacts for connection to system wires. The pin plug and socket plug can be coupled together for connecting the first and second socket contacts with pins secured in the pin plug. A short-circuit bridge is integrated in the socket plug for short-circuiting two of the second contacts when the pin plug and socket plug are uncoupled. An electrical filter component is integrated in the pin plug, the filter component being connected in series between one of the first socket contacts and a respective second socket contact upon coupling.
