Abstract: A contact device for a cable comprising one or more inner conductors with inner insulating sheath and a common shield with outer insulating sheath, comprises a connection terminal for the shield and a connection element for each inner conductor. Further a guiding element and a stop element are provided for each inner conductor. The guiding element directs the corresponding inner conductor with its insulating sheath at the corresponding stop element in such a manner that during insertion of the cable into the contact device the inner insulating sheath is axially compressed by the stop element by the stop element. Seen from the corresponding guiding element each connection terminal for an inner conductor lies beyond the corresponding stop element. By application of this contact device it is no longer necessary to remove the inner insulating sheath.

Abstract: A card edge connector for printed circuit boards is disclosed which employs a double-decker design. The connector may have the same length and width as conventional connectors used on Industry Standard Architecture (ISA) personal computers but is deeper. Conventional 8- and 16-bit ISA accessory circuit boards may be plugged into a corresponding socket which is also disclosed herein until they reach a stop upon which they rest, working as they would in an ISA personal computer. 32-bit Extended Industry Standard Architecture accessory circuit boards have a second row of connectors and a notch so they slide farther down into the socket, lining up with a second row of contacts. This design uses less physical space for connectors, allowing more room for logic circuitry on the motherboard.
