Abstract: A circuit board mountable shielded data link electrical connector (2) comprises a generally rectangular insulating housing (4) and a metal shield (6). The shield (6) covers the upper side wall (14), opposite end walls (18), mating end (10) and the part of the lower side wall (16), of the housing (4). The upper side wall (54) of the shield (6) has an extension in the form of a rear wall flap (62) which can be bent down about notches (66) to cover the rearward wall (12) of the housing (4) when the housing (4) has been inserted into the shield (6), and secured in position by means of rearwardly projecting flanges (76) on the opposite end walls (56) of the shield (6).

Abstract: An electrical conductor has a dielectric housing having an elongate cable receiving cavity opening onto a rear surface thereof. The cavity extends away from the rear surface blind ending at a wall. The cavity defines a major axis between the rear surface and the wall. The cavity also defines a bottom wall extending from the rear surface to the wall. The bottom wall has rib means thereon extending into the cavity and extending from the rear face substantially to the wall means. Insulation piercing contacts are secured in contact receiving passages that extend transverse to the axis and intersect the cable receiving cavity. The passages intersect the cavity at the bottom wall proximate where the cavity blind ends. The insulation piercing contacts have a mating surface and an insulation piercing surface and are adapted to be pressed toward the cavity subsequent to insertion of insulated conductors therein.

Abstract: There is disclosed, a kit of parts for assembly to provide a wire-to-wire shielded electrical connector (2) comprising an insulating housing (4) having a forward portion (12) defining a socket (50) for receiving a shielded electrical plug (170), and a rear portion (10) defining a row of passageways (18) for receiving respective wires (W) of a shielded electrical cable (C). Electrical terminals (6) have insulation displacement portions (84) which, in the assembled connector (2), are received in first slots (16) in the rear housing portion (10), and retention portions (86) which are received in second slots (66) in the forward housing portion (12), with contact springs (90) projecting from the retention portions (86) into the socket (50) for engagement by contacts (174) of the plug (170). The insulation displacement portions (84) of the terminals (6) can be driven home into the first slots (16) to engage the metal cores of the wires (W) when the wires (W) are received in the passageways (18).

Abstract: A shunt assembly (20) adapted to be secured on a connector (22) or a shunt connector assembly (24) where the electrical connector (22) has a housing (26) with spaced contacts (62) secured therein. The contacts (62) have exposed contact portions along a side wall (32) of housing (26). A contact support lever (152) is pivotally mounted to housing (26). The contact support lever (152) has an inner surface (250) having interdigitated channels (254,256,258,260,262,264) has a pair of shunt contacts (156,158) received and secured therein for engaging a surface of the exposed contact portions of preselected ones of the spaced contacts (62). The contact support lever (152) is rotatable through a limited arc from a first position with the shunt contacts (156,158) engaging the spaced contacts (62), to a second position where the shunt contacts (156,158) are electrically isolated from the spaced contacts 62.

Abstract: A one-piece metal cable guide member for guiding an undersize cable into a shielded plug housing which has a cable supporting base (18), cable locators (24, 25) upstanding from the base (18) in spaced apart relation to locate between them an insulated conductor row (42) and cable sheath (41) and shielding flanges (26) upstanding from the base (18) to extend along a rear end between opposite side edges of the base (18) and the cable locators (24, 25). The cable guide member is inserted front end leading into the mouth (31) of the plug cavity guiding the conductors (41) into pathways communicating with the mouth with the shielding flanges (26) completely closing and thereby shielding the mouth (31) on each side of the cable. The cable shield (43) is pressed against the base (18) which connects directly with flaps (36) extending into the mouth from the housing shield (35).

Abstract: Pin receptacle intended for mounting in a circuit board comprises a hollow metallic cylindrical member having first and second ends. A contact lance is struck or sheared from the cylindrical member and has a fixed end that is adjacent to the second end of the cylindrical member. The contact lance extends inwardly from its fixed end to the interior of the receptacle and has a pin contacting portion intermediate its ends. An end portion of the lance is reversely curved and extends through the opening formed by the shearing operation to the exterior of the cylindrical member. A circuit board conductor contacting portion is on the end of the lance. Stop lances are also struck from the cylindrical member adjacent to the second end and extend obliquely from its surface. Anti-overstress lances are also struck from the cylindrical member and extend obliquely towards the second end of the cylindrical member.

Abstract: A socket assembly for an incandescent lamp having a glass wedge base comprises a housing having a bulb-receiving face, a rear face, a bulb-receiving cavity extending into the bulb-receiving face, and a pair of passageways extending into the rear face and communicating with the bulb-receiving cavity. A stamped and formed contact terminal is inserted in each of the cavities, each terminal having a socket portion disposed in the bulb-receiving cavity and a wire-contacting portion proximate to the rear face. The wire contacting portion has a wire-receiving slot therein and an integral retaining finger extending from the rear face across the entrance to the wire-receiving slot of each terminal. In use, the housing is mounted on a panel having a hole therein which receives a bulb. Wires are connected to the terminals by first flexing the retaining fingers and placing the wires in the entrance portions of the wire-receiving slots of the terminals.

Abstract: Terminal receptacle which is receptive to a conductor at each end thereof comprises a channel-shaped member having a web and sidewalls. Openings are provided in the web and first springs extend obliquely across these openings from the web towards one of the sidewalls. Second springs extend from the upper edge of one of the sidewalls obliquely towards the other sidewall and towards the web. Conductors are connected to the receptacle by inserting the wires between the free ends of the springs and the adjacent sidewalls. Overstress-prevention ears extend inward from one of the sidewalls between the springs to prevent overstressing of the springs.

Abstract: Electrical commoning means for connecting a plurality of wires to each other at an electrical junction comprises an insulating housing having a terminal-receiving face and having a plurality of side-by-side terminal-receiving cells extending inwardly from the terminal-receiving face. Adjacent cells are separated from each other by a barrier wall having a centrally located opening which permits communication between adjacent cells. The wires which are to be commonly connected have contact terminals on their ends which are dimensioned to be snugly received in the cells. Each terminal has a contact spring extending from one side thereof and a contact surface on the oppositely facing side. The springs are dimensioned such that they will fit in the openings in the barrier walls and in their normal unstressed condition, each spring extends through the adjacent barrier wall and into the next adjacent cell.

Abstract: A thin, board-to-board zero force insertion and withdrawal connector having a housing containing a plurality of contacts with a first end portion of the contacts secured therein. A pair of parallel rows of rib-like elements extend along the length of the housing and define a U-shaped slot into which the edge of a circuit board can be inserted. The ribs form grooves therebetween which are perpendicular to the rows of ribs. The other end portion of each of said contacts extends downwardly into a groove towards the inner sides of said rib-like elements defining a side of said U-shaped slot, and then further extends upwardly towards the outer side of said rib-like elements. A plate is positioned along the length of said housing and secured thereto by a flexible hinge which divides the plate longitudinally along its length into two sections. A first of these sections extends over the said other end portions of said contacts. The other section of said plate has inclined planes formed on the inner surfaces thereof.
