Abstract: An electric motor assembly in which a one piece connector housing is mounted generally concentrically upon one end of the stack of core laminations, with alignment thereof obtained between the alignment holes in the core laminations and given points on the housing. The housing contains contacts constructed to terminate both the motor field coil ends and lead wires, without solder if desired, and by automated means, if desired.

Abstract: In an electrical component support assembly, the lead wires (which are of different gauges) of electrical components, e.g. resistors, are each gripped by the walls of two slots of identical slotted plate terminals. The two slots of each terminal are of the same minimum width but the two slots are laterally offset from one another and the two plates in which the slots are formed are resiliently connected and are formed so that the plates are mutually displaced laterally as the wires are inserted into the slots, whereby the smaller gauge wires are securely gripped between the two plates.

Abstract: An electrical connector includes slotted plate contacts which are received in cavities in a housing of insulating material. A stuffer forces wires successively into the slots of the slotted plate contacts when moved along a channel in the housing.

Abstract: An electrical tab receptacle for mating with a complementary tab is provided with an integral tongue having a lance whereby the receptacle can be releasably secured to the tab, the tongue being resiliently depressible by means of a finger, a tool, or part of a housing containing the receptacle, to release the receptacle from the tongue.

Abstract: An electrical connector housing for securing an electrical terminal in a passageway thereof, the passageway includes a first stop means integrally formed from a first area of the passageway and against which a section of the terminal engages to limit movement of the terminal in one direction in the passageway and a second stop means integrally formed from a second area of the passageway and being spaced from the first stop means, the second stop means defining stiffly-flexible means provided with free end means engageable with another section of the terminal thereby limiting movement of the terminal in another direction in the passageway.

Abstract: A terminal for connecting a fine magnet wire to a larger wire with relatively thick insulation. The terminal has a barrel at one end section thereof with serrations extending substantially circumferentially around the inner surface thereof. At the other end of said terminal there is a second barrel with tangs extending inwardly therein. The fine magnet wire is laid within the end of the barrel containing the serrations. The large wire with the heavy insulation is laid within both sections of said barrel including the portion containing the tangs and the portion containing the serrations. Crimping of both barrels in the terminal causes the heavy insulation on the large wire to force the magnet wire into the barrel serrations, thereby elongating the magnet wire and breaking the shellac or fine plastic insulation thereon so that the magnet wire makes electrical contact with the barrel.

Abstract: An electrical connector is attachable to an insulated electrical conductor wire and insertable partially through a hole defined through a printed circuit board after attachment of the connector to the wire in order to retain a bared end portion of the wire in a desired predetermined position between the sidewalls of the hole and substantially below the top surface of the board prior to the formation of an electrical solder connection between the bared end portion of the wire and an electrical conductor formed on the bottom surface of the board. The connector is comprised by a base having rearward and forward portions, a first pair of sidewalls extending outwardly from opposed longitudinal sides of the rearward base portion, a second pair of sidewalls extending outwardly from opposed longitudinal sides of the forward base portion, and a pair of resiliently flexible hook-like members projecting from the second pair of sidewalls.

Abstract: An electrical connector assembly includes a male contact having cantilever contact springs diverging rearwardly from a forward yoke portion to a position of maximum divergence and a female contact having cantilever contact springs extending forwardly from a yoke portion. The male and female contacts engage by outward flexure of the contact springs of the female contact and concomitant inward flexure of the contact springs of the male contact.

Abstract: A low profile contact, stamped or cut from a section of flat stock material, for receiving a male pin for connection to a lead of a printed circuit board, includes a cylindrically shaped pin receiving portion for insertion into a hole in the printed circuit board conterminous with the lead. A plurality of tabs extend upwardly from the top of the cylinder, and a pair of opposite tabs are bent intermediate their ends to partially extend into the cylinder to engage the inserted pin. The tabs are flared outwardly from the top of the cylinder to provide a guide to assist insertion of the pin into the cylinder and to provide a seat upon which the contact seats upon the surface of the circuit board. The cylinder is formed with a gap or space parallel to its axis to enable it to be radially compressed upon insertion into the hole of the printed circuit board to urge or bear outwardly upon the walls of the hole to establish firm physical and electrical contact therewith.

Abstract: Wire insertion and trimming apparatus comprising two wire locating combs opposed on opposite sides of a connector-supporting bed, a wire insertion and trimming ram reciprocable relative to the bed, and a third comb movable from a position remote from the bed to a position adjacent the bed to permit loading the connector onto the bed and wire insertion. Preferably, means are provided to latch the third comb remote from the bed which means are releasable by loading a connector and the two combs are movable after wire insertion in cooperation with the latching means to eject the connector.

Abstract: A matrix connector comprises an elastomer body presenting a pair of opposite contact faces at each of which is disposed a multiplicity of spaced contacts, contacts of opposite faces being interconnected by conductors extending through the body and being defined by convex folds in the conductors. Individual rows of contacts and their conductors are formed on flexible printed circuit laminae of which edge portions are turned to define the folds. A stack of laminae alternating with elastomeric strip material define the connector. Manufacture is suitably by compressing such a stack of extrude the elastomer through apertures in the printed circuits and curing the elastomer into a homogeneous mass.

Abstract: A free standing all metal contact, which, when mounted on a first board with other similar contacts, all in a straight line, will mechanically receive and hold, and make electrical contact with a second circuit board. Each contact has U-shaped configuration with the two legs of the U having a width which is normal to the plane of the U. The edges of each of the two legs are bent back in a direction away from the other leg to form an I beam type cross-sectional configuration to provide structural strength. Two of the bent back edges which are diagonally positioned are extended beyond the closed end of the U to form a pair of posts which fit into mating holes in the first circuit board to securely mount the contact thereon. The free end of one of the legs is bent downwardly into the U and towards the other leg to provide a spring-like gripping effect upon the edge of the second board when it is inserted into said U.

Abstract: An electrical contact for use in a printed circuit board edge connector comprises a pair of channel cross-section arms each providing a pair of contact surfaces for engaging a board mated with the contact, the arms being relatively rigid and thus providing high contact pressures.

Abstract: A tool for inserting either single loose pins or a plurality of pins or posts carried upon a mounting strip into holes of a substrate, such as a printed circuit board, in a continuous process and including a push blade and a carrier control blade for receiving the pins and the mounting strip which are carried upon a mounting frame. A plurality of ribs protrude upwardly from the push blade, forming grooves therebetween into which the pins to be aligned for insertion are positioned. A slideable, securing blade, carried upon the mounting frame, is moveable from a position away from the pins to a position engaging the pins to secure them in their aligned positions. A locking mechanism on the securing blade cooperates with the mounting frame to lock the securing blade in the engaging position.

Abstract: A short-circuit protection circuit for use in an arrangement in which a load is connected to a source of electrical power by way of switch, operates to open the switch only when a true short circuit condition exists, the circuit discrminating between a true short circuit condition and short duration high current surges caused, for example, by bouncing of the contacts of the switch or transient characteristics of the load.

Abstract: A logic detect circuit chip is mounted on a substrate having a plurality of first conductors on one surface connected to first inputs of respective bit-gates of the logic circuit, and a plurality of further conductors on the same surface connected to the other inputs of respective bit-gates. The further conductors are traversed by at least one bus conductor on the other surface of the substrate. The further conductors are selectively connectible to each bus conductor by conductive slugs at the crossing points. The bus conductor and the first conductors are connectible respectively to a 0 volt reference line and a parallel binary transmission line. By appropriate selection of the slug connections between further conductors and the bus line the detect circuit may be associated with a particular binary number on the transmission line. Two bus lines may be used, connected respectively to 0 volts and a different voltage reference.

Abstract: A hollow sealing member open at one end for receiving an electrical connector has at its opposite end, a wall formed with a plurality of recesses closed by a frangible base. The shape of the recesses permits a relatively wide flat tab to be passed through the wall without reducing the sealing effect of the wall around the conductor to which the flat tab is crimped.

Abstract: A method and apparatus for feeding a pair of wires in which the length of the fed wires may be varied relative to each other and also in which accurate positioning of the wires at the receiving station is accomplished. At the start of a cycle of operation the leading end portions of a pair of supply wires are engaged by wire clamp means immediately adjacent a wire support. The wire clamp means is then moved to an extended position to feed the leading end portions away from the wire support, and as the wire clamp means is being moved to its extended position a bight is formed in one of the wires to vary its length relative to the other wire. A trailing portion of the pair of wires is now cut and the insulation is stripped from the trailing end portions of the cut wires as well as the new leading end portions of the pair of supply wires.

Abstract: A terminal capable of being secured to a flat wire to make electrical contact with the conductor in the wire. The terminal is secured to the wire by pressing the wire between adjacent parts of the terminal so that electrically conductive barbs on the terminal pierce the insulation on the wire to contact the conductor.A pair of terminals capable of being secured to a flat wire having two spaced conductors so that each terminal in the pair makes electrical contact with one of the conductors in the wire. The terminals are coupled to each other by a weakened portion. While coupled, the terminals define a generally U-shaped member so that the wire can be confined between the legs of the U while it is being secured to each of the terminals. The terminals are secured to the wire by pressing it between adjacent parts of each terminal so that electrically conductive barbs on each terminal pierce the insulation on the wire to contact their respective conductors.

Abstract: A matrix connector comprises an elastomer body presenting a pair of opposite contact surfaces at each of which is disposed a multiplicity of spaced contacts, the contacts of the opposite faces being interconnected by conductors extending through the body, the contacts are defined by folds of the conductors extending through the elastomeric mass, convex portions of the folds being exposed at the opposite faces. Suitably such a connector is made forming the conductive strips on opposite faces of a flexible printed circuit, and interconnected at overlapping portions through holes in the flexible lamina. The lamina is folded in concertina form with adjacent limbs spaced by strips of partially cured elastomer. The assembly is then compressed and cured.
