Abstract: A wall covering is provided for supplying an electric receiver with power at variable positions on the wall, which covering is in the form of elements such as a carpeting tile with textile wearing layer (10) and an underlying insulating foundation layer (12) under which are fixed two assemblies of conductors in the form of strips (14, 14') of opposite polarities, covered on their lower face with a covering sheet (15), the tile possibly including electric connection means such as projecting ends (16, 16') of the conducting strips, the strips being designed for supplying with two phase power a current sensor having contact needles passing through the wearing layer (10) and the insulating layer (12) so as to come into contact with the conducting strips.

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: A pair of elements for providing slidable electrical contact therebetween wherein the contact surface of at least one of the elements comprises a plurality of contact portions and a plurality of depressed portions in between the contact portions so that wear particles which are generated between their contact surfaces as the elements are moved relative to each other are effectively swept from between the contact surfaces into the depressed portions where they are entrapped. Such operation tends to maintain a low electrical resistance between the elements over many cycles of use.

Abstract: A connector for connecting electrical wire comprises electrically conductive blade means having an elongated edge, guide means for guiding a wire inserted into the connector past the blade means, and retaining means for retaining the free end of the wire if doubled back and reinserted into the connector on the opposed side of the blade means. The bend formed in the wire engages the blade edge and is drawn therealong if the wire is pulled back to create a slicing action through the wire's insulator which produces a very clean high integrity electrical engagement of the wire's conductive core with the blade edge. Means are provided for wedging the bend formed in the wire tightly against the blade edge if the wire is pulled back to effect a secure mechanical connection of the wire to the blade means.

Abstract: A closure which includes a casing and an insulation displacement connector. The casing includes first and second fixed-sized passageways with an insulation placement connector disposed within each of the passageways. The connector includes a pair of spaced-apart walls each having at least one slot therein for receiving a wire. The slots in each pair of spaced-apart walls are laterally offset from one another.

Abstract: A cable termination sub-assembly is provided for electrically terminating insulated conductors of an electrical cable exteriorly of the housing of a shielded electrical connector, the sub-assembly being adapted for attachment to the housing subsequent to electrical termination of the cable conductors. The sub-assembly includes an insulative contact holder and an insulative conductor holding block that are adapted to be joined together in terminating insulated conductors of an electrical cable. A contact holder supports a plurality of electrical contacts each having an insulation displacement portion and a deflectable terminal portion. The conductor holding block includes means for frictionally retaining insulated conductors individually therein. The block further supports insulatively a pair of electrically conductive shorting elements, each element including a pair of spaced, exposed terminals.

Abstract: An electrical connector, especially for making connection to a fine, varnish insulated wire, comprises a terminal and a housing for receiving it. The wire is carried in slots in the housing. The terminal comprises a pair of wire gripping plates which are urged resiliently together in contiguous relationship. As the terminal is inserted into the housing, the plates are initially cammed apart by wedges in the housing so that the wire is received between the plates. Upon full insertion of the terminal, the wedges enter notches in the plates so that the latter resile to grip the wire the insulation of which is pierced by serrations on one of the plates. Frictional wear on the wire is thereby avoided.

Abstract: An electric multiple-socket end connector has registering housing shells which present sets of openings for receiving plug blades and interlock when pressed together by way of flexible legs with locking feet on one of the shells which pass through passages in the other shell. These legs deflect while the feet pass through the passages whereupon the legs spring back causing the feet to snap into locking position. The housing shells present a central wireway between two conductor plates registering in the housing shells with sets of openings for receiving plug blades. These plates have extensions presenting cord piercing contact barbs to make electrical contact with the wire leads in an insulated cord held in the wireway when the housing shells are pressed together.

Abstract: Disclosed is an arrangement for providing an electrical connection to the enamelled wire of a coil of an electrical motor. The arrangement includes a circuit board carrying at least one conductive component such as an electrical trace on the surface of the circuit board. A conductive pin-type contact, also carried by the circuit board, is electrically connected to the conductive component. An insulating body is carried by the electrical motor and includes passageways for receiving at least two pin-receiving receptacle terminals. The receptacle terminals have inwardly-extending rib members for engaging the enamelled wire when the enamelled wire and the pin-type contact are inserted therein. The rib members are operative to penetrate the enamel covering to establish electrical contact with the wire.
