Abstract: An illumination device for producing uniform illumination of a surface, comprising several parallel optical conductors which are placed above an optically reflecting surface, and whose reflecting outside sheath is removed locally at least in such a way that the light thereby emerging from the optical conductor is reflected by the reflecting surface to the surface to be illuminated. The optical conductors are spaced at such intervals and placed at such a distance above the reflecting surface that the light reflected by the reflecting surface can reach the surface to be illuminated on the other side of the optical conductors through the space between the optical conductors in such a way that the most uniform possible illumination of said surface is obtained.

Abstract: A power connector for connecting a multiconductor cable and a printed circuit board. The power connector includes a connector block with two pivotable longitudinal walls, each having a comblike edge which, when pivoted upwards, meet to define a plurality of slots which receive and maintain the conductor of the cable. The connector block is received within a connector cover, and the assembly is mounted on a pin holder disposed on a base plate. The contact pins of the pin holder project upwards to contact the conductors of the cable and downward to contact the printed circuit board.

Abstract: A contact strip for the electrical connection of at least one flat conductor of a flexible conductor film, which contact strip comprises a strip-type base part of electrically conducting material and at least one group of teeth projecting outwards from a surface of the base part, for cutting through the flexible conductor film and contacting the conductor while the teeth can be deformed in the direction of the base part to press the base part. According to the present invention the base part comprises at least a second group of teeth projecting outwards from the surface of the base part, in which the first and second group of teeth are positioned within the periphery of the strip-type base part. All teeth of a group are arranged in a closed peripheral line such as circle, ellipse, triangle, square or other geometrical polygon and the distance between these teeth is smaller than the smallest dimension of the flat conductor to be contacted.

Abstract: An edge connector for electrically contacting a substrate. The substrate is held within connector housing by the force provided by a clamp means hingedly disposed within a cutout in the housing. The clamp means includes a spring portion, a clamp portion and a strike portion. The insertion of the substrate causes the clamp means through the action of all three portions to secure the substrate within the housing. The substrate can be released by hand.

Abstract: A pierce contact element for a connector with a housing in which the end of a cable with one or more insulated conductors is inserted. The pierce contact has a pointed part intended to pierce into an insulated conductor and a contact crown intended to make contact with the contact strip or contact wire of a matching connector housing. The contact crown is shaped so that its radius of curvature is larger than half the width of the contact crown in order to reduce wear on the surface contacting the strip or wire of the matching connector. In one embodiment, pierce contact is designed so that its pointed part pierces in the longitudinal direction into the end face of the conductor.

Abstract: An edge connector is provided capable of interconnecting the conductors on a flexible conductor film and the conductors on one or more rigid substrates, such as for LCD or LED displays. The edge connector includes a plurality of clamping contact elements, each with at least three contact arms defining at least two insertion openings, one for the rigid substrates and one for flexible film. A fourth arm may be included to define a third insertion opening for a second rigid substrate.

Abstract: An optical fiber connector having two half-round holding members mounted in a central coupler. The half-round members have flat mating surfaces with an opposed longitudinal V-groove for receiving fiber ends of either similar or dissimilar diameters. The opposed fibers spread the holding members away from each other; an elastic member retains the holding members in opposed relationship.

Abstract: An end connector for flexible printed circuits, with a folding casing of insulating material. The connector is suitable to receive and contact through contact means the edge part provided with parallel conducting strips of a flexible circuit. The bottom of the casing contains a resilient means and cams for positioning the flexible circuit in the connector.

Abstract: An improved electrical connector including dual contacts comprising an insulating support, an arcuately stressed spring having each end confined within the support, and a flexible printed circuit stretched over the spring is provided. The contact function is accomplished by the flexible circuit. The spring is adapted to deflect and resiliently flex at its midpoint during engagement with a mating contact at which time the spring surfaces on both sides of their midpoints resiliently press the flexible circuit against the mating contact. The resilient flexure of the spring provides redundant pressure points between the flexible printed circuit and the mating contact and eliminates the need for a spring having both the sufficient resilience and the necessary conductive properties.

Abstract: A flexible printed circuit has printed electrical contacts which are spring loaded to corresponding integrated circuit contacts or to corresponding other circuit contacts to form a connector.

Abstract: An electrical connector includes an improved dual metal contact comprising a support and an arcuately stressed plate spring having each end fixedly mounted to the support. The spring is adapted to deflect and resiliently flex at its midpoint during engagement of a mating contact, at which time the spring surfaces on both sides of its midpoint resiliently engage the mating contact. The initial deflection of the midpoint of the arcuately stressed spring provides for a low insertion force, and the resilient flexure of the spring provides a redundant contact surface with enhanced contact force between the surface of the spring and mating contact.

Abstract: A contact assembly is provided comprising a plastic housing including a pair of spaced rows of terminal receiving cavities and a contact in each cavity. Each cavity has a flexible wall, and a link having one end connected to the flexible wall and the other end engaged with a drive operatively mounted between the spaced rows. The drive extends each link, flexes the wall and engages a male terminal inserted in each cavity with the contact in each cavity to establish an electrical connection between the terminal and the contact.
