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: An RF plug connection system includes a contact part which can preferably be crimped to an RF conductor in an RF cable, an insulating part that holds the contact part, at least one insulation-piercing terminal contact holder which can be disposed on the RF cable and an intermediate housing which holds and preferably guides the insulation-piercing terminal contact holder. The insulation-piercing terminal contact holder has at least one blade which makes contact with an outer conductor of the RF cable when the insulation-piercing terminal contact holder is pressed against the RF cable. An outer housing is fitted over the intermediate housing.

Abstract: The electrical connector has a basic body, at least one contact element inserted into the basic body, and a contact-ensuring slide. The slide is brought into engagement with the basic body and, when it is properly engaged, the contact element is ensured not to be displaced from its proper position in the basic body. The basic body and the contact-ensuring slide are formed with guide elements for specifically guiding the basic body and the contact-ensuring slide when the latter two are brought into engagement. Latching elements latch the basic body and the contact-ensuring slide. The guide elements and the latching elements of the electrical connector are spatially separated from one another.

Abstract: The one-piece contact spring has two spring arms, bent back inwardly in a box-shaped contact part. The spring arms are supported on a support which helps relieve the bend. The support is recessed into the box interior from the forward end of the bend by approximately two to five times the thickness of the bottom or top wall, respectively. A preferred embodiment of the one-piece contact spring has spring arms supported by support arms stamped and bent out from the bottom wall and the top wall.
