Abstract: A chip carrier socket comprises a frame which defines and surrounds a space for receiving a chip carrier. A plurality of elongated contacts are carried by the frame, the contacts each defining a first section which resides within the inner surface of the frame, and are positioned to conductivity engage peripheral contacts of a chip carrier carried in the space. The contacts also each define a second section positioned on one side of the chip carrier socket to engage conductive members of a circuit board when the socket is carried thereon. The second sections each define a contact end which projects inwardly. The chip carrier socket defines an open aperture within and through the frame adjacent the inner surface so that the inwardly projecting contact ends are visible while the socket is carried on a circuit board.

Abstract: A method of connecting a relatively large diameter, multistrand wire with a relatively small diameter wire. The method comprises: (1) Flattening a portion of the large diameter, multistrand wire into a body of reduced first transverse dimension and an increased second transverse dimension. Simultaneously, one heat welds the strands of the body into a unitary, coherent mass. (2) One cuts away outer portions of the unitary, coherent mass to reduce the increased second transverse dimension of the mass produced by the flattening step. (3) Then, one heat welds the unitary, coherent mass to the relatively small diameter wire.

Abstract: An electrical switch assembly comprises a first, domed, flexible contact member plus at least one second, flexible, finger-type contact member positioned under the first contact member in normally spaced relation thereto. Actuator means are provided for pressing the first, domed contact member into contact with the second contact member to actuate the switch assembly. In accordance with this invention the second, flexible, finger-type contact member defines an end portion which is bent to permit increased-area contact with the first contact member when the first contact member is pressed into contact with the second contact member. This also provides improved wiping action between the first and second contacts as the increased-area contact is made and broken for removal of carbon build-up and the like.

Abstract: An electrical interconnector comprises an outer housing defining a first aperture; a rotor member occupying the first aperture in rotational relation to it; the first electrical connection carried on the outer housing; a second electrical connection carried on rotor member; and a coiled conducter wire loosely coiled in a plurality of coils about the rotor member with the outer housing, the coil conducter wire being connected at respective ends thereof to the first and second electrical connections. In this invention, one or more recesses are carried on either the outer housing or rotor member. One or more flexible detents are carried by the other of the outer housing and rotor, the detents being normally positioned to project into the recesses to prevent rotation between the outer housing and rotor member.

Abstract: A fiber optic contact comprises a fiber optic cable having a first free end, and a sleeve member surrounding the first free end and proportioned to support the first free end in abutting relation with a second free end of another fiber optic cable for optical transmission between them. In accordance with this invention, a collet is slidably mounted on the sleeve member. Compression spring means are carried on the sleeve member between the collet and the first free end, so that the contact may be retained in the desired abutting relation by retention means that engages the collet in a position to bias the first free end against the second free end through the spring means.

Abstract: A solder button may be attached to an elongated conductor by substantially surrounding a portion of the conductor with a mass of solder. The mass of solder may be crimped or heat welded into fixed position onto the elongated conductor, which is typically in ribbon form, with the solder being cut from a strip of solder by cutting and crimping means, the strip of solder being in transverse relation to the conductor at the crimping means. The elongated conductor, with attached solder buttons, may be attached by automated means in a single step to a pane of glass or the like.

Abstract: An electrical contact having a compliant section for mounting the contact on a circuit board in a plated-through hole. The compliant section includes a section having a configuration which deforms upon insertion into the circuit board hole and creates positive electrical contact at three points. The contact may include a wire wrap tail and an upper pin or post to mate with a connector.

Abstract: A clock spring interconnector provides electrical connection between a rotating and nonrotating electrical circuit. In the interconnector, an outer housing defines a fist aperture extending therethrough. A rotor member occupies the first aperture in rotational relation to it. First conductor wire means are carried by the outer housing, while second conductor wire means are carried by the rotor member. Coiled conductor means are loosely coiled in a plurality of coils about the rotor member within the outer housing, with the coiled conductor means being connected at respective ends to the first and second conductor wires. The rotor member defines a second aperture extending through it in generally coaxial relation with the first aperture.

Abstract: A connector for fiber optical cable inluding a ductile metal sleeve, a portion of the fiber optical cable adjacent its end being positioned within the sleeve, with the end of the fiber optical cable projecting from a hole through the end of the sleeve. The portion of fiber optical cable adjacent its end is stripped of substantially all insulation and sheathing, while a resilient tubular insert surrounds such portion which is adjacent the cable end, the tubular insert in turn being positioned within the metal sleeve. The metal sleeve is crimped to hold the sleeve, tubular insert, and stripped adjacent end portion together in immovable relation. By means of this invention connectors may be placed on optical cable, capable of withstanding excessive cable retention, without the use of adhesives.
