Abstract: Capacitive coupling assembly (60) securable about a shielded connector (10), for isolating the connector shell (14) from a conductive panel (4) after mounting. Coupler (60) includes a dielectric member (61) secured between front and rear conductive sheets (62, 63), and includes a plurality of capacitors (72) held between the sheets and electrically engaged therewith. The dielectric member (61) includes a flange (67) that insulates the connector shell (14) from front conductive sheet (62) and the panel (4) at cutout (5). Front sheet (62) engages the panel (4), and rear sheet (63) engages the connector shell (14) at spring arms (78).

Abstract: Capacitive coupling adapter (40) associated with a shielded electrical connector (12) and including at least one capacitive subassembly (54). Each capacitive subassembly (54) includes a capacitor (46) and a pair of contacts (50,52) engaged with respective electrodes thereof. One contact section (68) of a contact (52) extends from a surface (58) of the adapter housing (42) to engage a shell of a connector (12), and one contact section (64) of a contact (50) extends from an outer surface of housing (42) to engage a cutout peripheral surface (14) of a conductive panel (16) when the adapter/connector (40,12) is mounted in the cutout. The connector shell (22) is thus capacitively coupled to the panel.

Abstract: An electrical connector (1,100) for a DIN rail (2) with rail flanges (6), including a body (3,102), a carrier (16,104) vertically movable with respect to the body (3,102), an actuator (14,110) and a pair of clamp members (5,106,108) having rail-engageable hook portions (26,148). At least one of the clamp members (5,106,108) is movable toward the other by the carrier (16,104) upon actuation for mechanically and electrically clamping onto a respective rail flange (6). A pair of such clamp members (5) may be cammed inwardly and upwardly along slots (30) in side walls (9) of body (3) upon actuation, or the clamp members (106,108) may include flanges (158) pivotably held in body side wall holes (162) for rotating the hook portions (148) inwardly and upwardly against the rail flanges (6). Such connector (1,100) is adapted to be mounted beneath a circuit board (10) prior to being clamped onto the DIN rail (2).

Abstract: An electrical connector (1) comprises conductive electrical contacts (3) within an insulating housing (2), and a conductive shield (40) encircling the housing (2); a latch (53) latching together portions (51,42) of the shield (40) to enclose the housing (2); and a projecting housing portion (37) impinged against the shield (40). The housing portion (37) biases the housing (2) against the shield (40) to immobilize the housing (2) at a desired position relative to the shield (40).

Abstract: An electrical connector (1) comprises electrical contacts (3) arranged in two contact rows on opposite sides of an insulator (6), with the contacts (3) in each row being spaced apart laterally one from one another, the contacts (3) being arranged in pairs with the insulator (6) being between the contacts (3) of each pair, mating contact portions (24) on each pair of the contacts (3) overlying each other in opposed spaced relationship, and electrical terminals (26) on each pair of the contacts (3) being offset from each other in lateral directions, and being offset from each other front to rear.

Abstract: An electrical connector comprises, a housing (2), conductive contacts (3) in the housing (2) extending toward a mating end (23) on the housing (2), channels (25) in the housing (2) receiving respective contacts (3), and core pin openings (34) in the mating end (23) communicating with the channels (25), wherein the channels are formed with precision in a slender mating end (23) on the housing (2).

Abstract: Electrical connector comprises an insulating housing having a wire-receiving face into which a cavity extends. A sheet metal terminal is disposed in the cavity and has a displation type wire connecting portion adjacent to the wire-receiving face. The wire connecting portion comprises an elongated metal strip which has been reversely curled inwardly to form a cylindrical surface adjacent to the face and a free end which is spaced from an intermediate portion of the terminal. A wire-receiving slot extends into the strip at the free end and a wire-receiving opening is provided in the curled strip adjacent to the wire-receiving face. In use, a wire is inserted axially through the opening so that the end of the wire is located between the free end of the strip and the intermediate portion of the terminal. The wire connecting portion is then subjected to a force applied against the cylindrical portion of the terminal which causes the wire connecting portion to be further curled.

Abstract: A switch assembly for a printed circuit board comprises fixed and movable contacts mounted on the circuit board and a separate switch housing mounted on the board which encloses the contacts. The housing has a slidable actuator cam therein which closes and opens the contacts, depending upon its position, and holds them in one condition or the other. The cam is actuated by an externally extending lever. An improved assembly method is also disclosed for assembling switches to circuit boards.

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.
