Abstract: A plug-in unit (112, FIG. 7A) with a housing (150) that receives an electrical contact arrangement (55, FIG. 6) that has a cable bushing (151, FIG. 7A). The housing has an aperture (153) in a housing wall for the plugged-in reception of the mating plug-in unit (11, FIG. 2). In order to allow for the optional design of an angled or a linear plug-in connection, the cuboid housing (150, FIG. 7A) is divided along a plane (180) that runs perpendicular to a longitudinal central plane (179) and at a 45° angle to the longitudinal extension of a bushing (151) in such a way that a first housing part (181) contains the cable bushing (151) and the second housing part (182) forms the plug-in aperture (153). The second housing part (182) is attached to the first housing part so the second housing part (182) can be turned with respect to the first housing part (181).

Abstract: A contact arrangement (10) comprising fork-shaped contacts (15) that engage opposite faces of a blade contact (18). For good heat dissipation together with low transition resistance, the contact arrangement is made up of multiple planar, i.e., plate-shaped, fork contacts (15), which are supported and connected to each other on a shaft-like carrier (16) that is joined to a perpendicular connecting unit (14).

Abstract: A connector (10) for systems of high power density includes a first (female) plug-in unit (11), a second (male) plug-in unit (12), and gear wheels (65) with spiral tracks (67) that engage cams (28) that move the units together.

Abstract: A plug connector (11, 12, FIG. 1) has insulators (16,26) that hold male or female contacts (13, 14, FIG. 3) received in boreholes (19, 29, FIGS. 4A, 4B)). A rear insulator holds a male or female contact (13, 14), which receives cables (45, 55, FIG. 3). The boreholes (19, 29) form fingers (78, 98, FIGS. 4A and 6) that can be radially spread apart to detachably hold the connector contacts (13, 14) in a preliminary locking manner. The plug connector also has a front insert (60, 80) with a front borehole (65, 85) aligned with the rear boreholes (19, 29) and being able to be placed in a non-detachable preliminary locking position that makes possible the attachment of the connector contacts (13, 14) and in a final locking position that holds the connector contacts (13, 14) in a non-releasable fashion.

Abstract: A plug connector device (10) for multicore flat cables (15), has a plug (11) which can be fixedly joined to one end of a flat cable in a mechanical fashion, and a plug socket (12) which can be run through by the flat cable (15) such that, with their first contact ends (62), contact elements of the plug socket (12) engaging in the plug (11) can be electronically connected to the flat cable at their other contact ends (63) using IDC technology. To assure that the plug connector device is robust and has high contacting reliability, provision is made that plug (11) is provided with contact elements (18), whose first contact ends (38) are configured for the electrical connection to the first contact ends (62) of the contact elements (19) of the plug socket (12), and whose other contact ends (36) are configured for the connection to the flat cable (15) using IDC technology.

Abstract: A sheet metal cover (11) for a PC card, or electronic card, includes identical top and bottom sheet metal cover parts (13, 12) with opposite sides constructed to allow the cover parts to be joined together by merely pushing the sides of the top cover part forcefully down against the sides of the bottom cover part. One side (23) of each cover part is bent and cut to form a plurality of latching lugs (37), and the other side (24) of each cover part is bent and cut to form a plurality of slots leading to recesses that each receives a lug and then resists movement of the lug out of the recess. Each lug has outer and inner legs (38, 39) that are joined in a fold of less than 90°. The slots each receives a lug only when the inner and outer legs of the lug are deflected closer together.

One side (23) of each cover part is bent and cut to form a plurality of latching lugs (37), and the other side (24) of each cover part is bent and cut to form a plurality of slots leading to recesses that each receives a lug and then resists movement of the lug out of the recess. Each lug has outer and inner legs (38, 39) that are joined in a fold of less than 90°. The slots each receives a lug only when the inner and outer legs of the lug are deflected closer together.

Abstract: An electrical contact (10) which can engage a mating terminal (50) for electrical connection and detachable latching thereto. The contact includes a piece of sheet metal bent to form at least one guide plate (13, 14) and a bias plate (15) lying facewise adjacent to the guide plate. The bias plate has a front end upper portion or nose (38) with a top (104) that lies above an adjacent location (24, 25) on the guide plate, but the nose can be resiliently downwardly deflected and then tends to spring up again. A recess (17) in the bottom of the guide plate front portion receives the mating terminal, and the upper bias of the nose of the bias plate keeps the guide plate pressed down against the terminal lying in its recess, to thereby latch the two connectors together.

Abstract: A PC card for insertion into a slot of a portable computer or other electronic device, has an antenna that allows the electronic device to send and receive data through radio waves. The antenna is moveable from a stowed position wherein most of the antenna lies in the PC card housing, and a first deployed position wherein most of the antenna projects rearwardly through an opening at the rear of the housing so radio waves can be transmitted and received. The antenna can be mounted on a tray that is moveable forwardly and rearwardly into and out of the rear of the housing. The tray can form a smart card-receiving recess that receives a small smart card to enable connection to pads on the smart card so as to provide authorization for communication through a wireless telephone network.

Abstract: A PC card of standard width and thickness (e.g. 54 mm and 5 mm) is constructed to receive a chip card of smaller width and thickness (e.g. 18 mm and 0.8 mm) so the PC card can used to connect contact pads of the chip card to an electronic device such as laptop computer into which the PC card is inserted. The PC card includes a sheet metal cover with a top cover portion (13) having a flat region that is deep drawn to form a ramp (30) that extends downwardly to an aperture (31). A chip card can be slid down along the ramp and through the aperture, and along an internal path portion in the card to engage contacts on a circuit board. Guides on opposite sides of the internal path portion can be formed by tabs (36, 37) partially punched out of the cover portion, parts fastened to the underside of the top sheet metal cover portion, and/or parts or components mounted on the circuit board.

Abstract: A PC card has an opening (24) in its upper sheet metal cover part for receiving a chip card (20), with a chip card guide (22) provided for guiding movement of an inserted chip card through the opening. The guide has a U-shaped upward projection (31) that lies in the opening against the rear and opposite sides of the opening. The guide has a ramp wall (32) lying under the opening to guide the leading edge of an inserted chip card. The guide is formed of a molded polymer with an upwardly-facing surface location (70) that is bonded facewise to the lower face of the sheet metal at a location immediately around the opening therein. The inserted card is stopped at a position where a portion of the chip card lies directly in the opening.
