Abstract: A connector of the plug and socket type comprises a housing (3) having a chamber (4) into which extend, one or more conductive pins (5). A second housing (8) is adapted to be received in the chamber (4). When the housing (8) is fully inserted in the chamber (4) the pins (5) pass through a first aperture (24) and a second aperture (25). Between these apertures, the pins are deformed by a projection (18) and retained thereby. The projection (18) forms part of a contact element (15) which is provided with tines (17) engaging the conductors of an inserted cable (12).

Abstract: An electrical shielding arrangement is provided wherein an edge connector (5) interconnects first and second circuit boards (1, 16). One of the boards (1) on which the edge connector lies includes a metal ground plane (2) and a plated through hole (3) which extends through the board and which makes effective contact with the metal ground plane. The plated through hole receives a metal fixing pin (4) of compliant metal which extends from the connector body (30) and is press fit into the hole (3). The forward end of the pin is positioned to engage a conductive layer (20s) at the leading edge of the second board, which is connected to the ground plane (19) of the second board. Thus, the pin (3) interconnects the ground planes (2, 19) of the two boards.

Abstract: An electrical connector comprises a body accommodating one group of staggered rows of spring contacts for engagement with cone-shaped contacts arranged in correspondingly staggered rows on a printed circuit board. The spring contacts of one row have intermediate flattened parts which slidingly engage with peaks of the corresponding dome-shaped contacts thereby requiring low insertion force while curved parts of spring contacts of the other row are riding up the convex profile of the corresponding dome-shaped contacts requiring high insertion force. Two similar groups of staggered rows of spring contacts may be provided for accommodating boards having staggered rows of raised contacts on both sides of the board.

Abstract: An electrical press-fit contact includes a compliant section (3) of substantially C-shaped cross-section and comprising first and second arm portions (4)(5) with a base portion (8) therebetween. The thickness of the compliant section increases steadily from the base portion (8) to the arm portions (4)(5) such that the center of the base portion is of least thickness to form a hinge about which the first and second arm portions may be preferentially deflected. The contact is formed by coining a portion of stock etc such that it has a planar first surface and an arcuate second surface sloping away from the first surface towards its edges. The coined portion is then folded to form the C-shaped compliant section with the first surface being the outer surface and the second surface the inner surface thereof.

The terminal block assembly is comprised of two portions. The first portion is a fixed block with apertures, each for receiving and supporting a blade contact in a predetermined orientation. The second portion of the terminal block is a movable block with barrels or pockets, each for receiving an electrically conductive wire, each of which wire terminates with a tab receptacle. Because of the design and construction of the portions of the terminal block assembly, the tab receptacles and their electrically conductive wires may be conveniently and reliably mounted onto the blade contacts in the fixed portion of the terminal block assembly and securely retained there.

Abstract: A method and apparatus for automatically making harnesses such as those used for electrically interconnecting a plurality of spaced-apart, separate connection points. Insulated wire is fed through a press position where terminals are attached to the wire conductor. The insulation is displaced from a portion of the wire where a terminal is to be attached, thereby baring the conductor. A terminal is brought adjacent the bared conductor from a supply of terminals and crimped to the conductor. A wire feeding mechanism advances the wire so that the section having a terminal crimped thereto is removed from the press position and a new portion is brought into the press position for the attachment of another terminal. The automatic process is repeated until a pre-determined number of terminals are attached to the conductor at which time the wire can be severed to complete the manufacture of the harness.

Abstract: Apparatus to automatically attach a terminal to electrical wire and thereafter to install insulating pods on the terminal. The apparatus includes a press which attaches the terminal to form a terminated wire and a transfer block which moves the terminated wire to an insulation pod installation station. The pods are delivered to the pod installation station in an interconnected fashion so as to form a strip of pods. The first pod on the strip is separated from the rest of the strip and placed on the terminated wire.

Abstract: A wire transfer mechanism for transporting a length of wire conductor from a feed location to a terminating location and then depositing the length of wire at a collection location is disclosed. The mechanism includes at least one transfer arm mounted for pivotable motion back and forth; a releasable gripper mechanism positioned at the end of each transfer arm for gripping a length of wire to inhibit relative motion in a direction normal to the axis of the wire, and an actuator mechanism for releasing the gripper mechanism while the transfer arms move from a wire terminating position to a wire pickup position at a finite velocity and for decelerating the transfer arms, so that the momentum of a wire gripped in the gripper mechanism will carry it away from the transfer arms in a direction normal to the axis of the wire.

Abstract: A method of fitting an electrical connector housing to an electrical contact comprises feeding a chain of connector housings linked end to end in the direction of their length towards a fitting station and, at said fitting station, effecting relative lengthwise movement between the leading housing of the chain and a contact in such a direction as to cause the leading housing to be fitted on to the contact.
