Abstract: A rotary connector assembly has a rotor with a receptacle for an associated electrical connector, stator contacts, first contacts arranged in the receptacle that make an electrical connection to contacts of the associated electrical connector, a housing in which the rotor is rotatably arranged, and rotor contacts arranged on the rotor and electrically connected to the first contacts that make an electrical connection to the stator contacts. The rotor contacts include wound wire on which the stator contacts abut laterary. The rotor contacts are arranged mutually spaced apart radially on a section of the outer circumference of the rotor. Leads to the rotor contacts have a portion arranged running in an axial direction in radial recesses of the rotor.

Abstract: An adapter assembly is provided for holding two individual fiber optic connectors in generally parallel side-by-side alignment. The assembly includes a body having a pair of through passages adapted for holding the fiber optic connectors in an substantially side-by-side relationship when the connectors are inserted in an axial direction into the passages. The passages are transversely enlarged relative to the respective connectors to provide floating motion between the connectors and the body. A holding clip is insertable into a transverse opening in the body into engagement with each connector. The holding clip retains its respective connector in its respective passage in the body. The holding clip is configured to allow the floating motion between the connectors and the body.

Abstract: An electrical connector includes a dielectric housing having a plurality of apertures receiving a plurality of terminals having pin portions projecting from the housing for insertion into complementary holes in a printed circuit board. At least some of the terminals are mounted in the housing for movement between first and second positions in response to mounting the connector to the printed circuit board. In the first position, the terminals are fixed relative to the housing to facilitate alignment and insertion of the pin portions into the holes in the printed circuit board. In the second positions, the terminals can float relative to the housing to accommodate a differential in thermal expansion between the housing and the printed circuit board. Other terminals are mounted in the apertures and maintained in a fixed position relative to the housing when some of the terminals are in floating positions.

Abstract: A press-fit contact is disclosed for insertion into a plated-through hole in a printed circuit board. The press-fit contact is rotationally symmetric (manufactured on a lathe). In order to secure a uniform contact pressure for the whole contact region, the press-in portion of the contact is formed in the shape of a convex barrel and includes an axially extending cylindrical cavity. The barrel-shaped walls are provided with longitudinal slots extending parallel to the axis of the contact. The slots do not extend up to the lower end of the contact defining resilient beams having their ends joined by a rim formed at the tip of the contact.

Abstract: A connector is disclosed having a plurality of contact elements to be pressed-in into contact holes in a printed circuit board. The contact elements are arranged in a housing of insulating material. In order to press-in all contact elements of the connector simultaneously into the respective contact holes of the circuit board such a large force has to be applied to the housing that the housing may be damaged. The contact elements are elongated to extend up to the top surface of the housing such that the insertion force can be applied directly to the contact elements.

Abstract: A right-angle printed circuit board connector includes a plurality of contacts arranged in a matrix having portions of the contacts extending from the connector terminating in a corresponding plurality of conductive areas laid out in a matrix on the printed circuit board. The extending contact portions are arranged such that the uppermost row is terminated in apertures located closest to the connector and the lowermost row is connected to apertures located the farthest from the connector - the length of all the individual being substantially equal.

Abstract: The method and the arrangement for the connection of a multipole connector to a circuit board (1), specifies that the circuit board (1) is provided with a plurality of blind holes (3), equivalent in number to and matching the location of terminals (4) extending out of the connector housing (2). The blind holes (3) are filled with solder paste (5) and the mechanical and electrical connection of the connector (2) with the circuit board (1) is carried out by reflowing the solder paste. Compared with the conventional technique utilizing through-drilled connection holes, the invention provides the advantage that conductor paths can be routed underneath the blind holes, soldering paste cannot get on the underside of the circuit board, and a tolerance compensation of the lengths of the terminals is insured without subjecting the circuit board to preload forces exerted by the terminals.

Abstract: A high density edgecard connector system includes a first row of cantilever contacts and a second row of cantilever contacts which are longer than those of the first row. The edgecard includes first and second rows of contact pads which are located differing distances from the bottom of the edgecard. Ribs are mounted on the edgecard between each of the contact pads in the first row and lift the cantilever contacts of the second row away from the surface of the edgecard in order to prevent cross connections between the cantilever contacts of the second row and the contact pads of the first row during insertion or withdrawal of the edgecard into or out of the connector. The ribs include ramps on either end and may be integrally molded with a spine which attaches to the bottom edge of the edgecard.

Abstract: A daughterboard connector (6) has a polarity key formed by two walls (14, 15) on either side of a recess (12). A lateral contact (8) mounted in the recess engages a bus bar (3, 4) which is mounted in a pair of slots (20) in the end of a motherboard connector (11). A flange (7) adjacent one of the slots forms a polarity key for the motherboard connector. The height and positioning of the lateral contact and the bus bar are chosen to provide a first-make-last-break function for these elements relative to the signal contacts 19 and 16 of the daughterboard and motherboard connectors, respectively. The bus bar (3, 4) may be common to a number of motherboard connectors which are mounted on a common printed circuit board.
