Abstract: An electrical contact element has an elongate three-dimensional body formed of a single stamped sheet metal piece and has a first end and a second end with a longitudinal center line extending from the first to the second end. The first end of the body has an insulation displacement contact with a first and a second pair of legs for receiving and contacting a cable. Each one of the first and the second pairs has an insertion slot defined between the legs. The second end of the body has a forked spring with a first and a second fork leg defining therebetween a receiving slot for receiving and contacting a flat blade plug. Each one of the fork legs consists of two independently elastically deflectable leaf springs. Each one of the leaf springs has at least one contact zone projecting inwardly into the receiving slot. The contact zones of the two leaf springs of each one of the fork legs are located laterally relative to the longitudinal center line.

Abstract: A plug connector for contacting a device, having a plurality of contacts and comprising flat plugs, includes a combination of a lockable flat plug sleeve and an insulation displacement contact.
