Wing members (15) have ends (15a) disposed in spaces (38) in the cavity (33).

The sides of one of the cavity portions, when taken in conjunction with the sides of the other cavity portion, complete the definition of the sides of the channels. A mold core pin (50) for forming the cavity portions is also disclosed.

Abstract: A connector assembly (100) for an array of discrete microcoaxial wires (10) includes a housing (102) with signal terminals (140) disposed therein having intermediate sections (154) exposed along a rearward housing section (114) for eventual solder termination to inner conductor ends (20) of the wires. The signal terminals of each row are initially joined to a respective carrier strip (146) until after soldering. A ground plate (50) is insertable into a medial slot (106) of the housing and includes an array of semicylindrical nests (56) formed to receive portions of the microcoaxial wires thereinto for soldering of ground ferrules (30) therearound directly to the nests (56) prior to insertion of the ground plate into the housing, thereby defining a wire-carrying subassembly (90). When the ground plate (50) is inserted into the housing (102), the stripped inner conductors (20) are positioned at termination sites (144) of the signal terminals (140) for soldering.

Abstract: An electrical connector (20) has a dielectric housing (22) with at least one channel (46) therein. A contact (26) having a mating end (74), a mounting end (84) and a body section (94) extending therebetween is disposed in the channel. The body section (94) between the mating end and the mounting end defines an axis. The body section also defines opposed first and second major surfaces (96,98). A first protrusion (104) extends from one of the major surfaces proximate the mating end (74) of the contact and a second protrusion (106 or 108) extends from one of the major surfaces at a location spaced from the mating end (74) farther than the first protrusion (104). In this manner the contact (26) is caused to resiliently bend forming an "S" bend which provides a slight interference fit at spaced locations along the length of the contact to retain the contact in the channel.

Abstract: An electrical wire connector comprises a female insulating housing receiving a male insulating housing. The female housing has anchored therein, a plurality of electrical terminals each having a wire receiving part comprising a pair of arms connected by a bight and defining a wire receiving slot between upper parts of the arms. The arms are resiliently deflectable away from each other as a wire is inserted into the wire receiving slot up to wire contact surfaces between the upper parts of the arms. The male housing has a row of wire receiving passageways each intersecting a slot in the male housing, which slot receives the wire receiving part of a respective terminal when the male housing has been fully inserted into the female housing. Wires previously inserted into the wire receiving passages are forced into the wire receiving slots of the terminals during the insertion of the male housing into the female housing. The parts of each arm are so dimensioned that the wire insertion force is desirably low.

Abstract: The terminal (2) comprises a stamped and formed metal pin socket (6) comprising a base (12) from which extend two contact springs (14) each comprising an L-cross section forward portion having identical parts (18 and 20) which extend at right angles to each other. Back from contact bosses (22) of the springs (14), each spring (14) has a longitudinal slot (28) which enables the parts (18 and 20) of each spring (14) to splay resiliently apart from each other when a square cross section pin (P) is inserted into the socket (6), without the pin insertion force or the contact force exerted by the contact bosses (22) against the pin (P), being excessive. These forces can be predetermined by suitably dimensioning the slots (28).

Abstract: There is disclosed a surface mount, circular DIN connector (10) with a housing (12) having a mating face (22) and a terminal receiving face (24). Three rows of terminal receiving cavities (1 to 8) open into the mating face (22) and the terminal receiving face (24). A set of electrical terminals (30) each has a mating portion (32) in a respective one of the cavities (1 to 8), a solder tail (36) extending substantially normally of the mating portion (32), and a connecting arm (38) connecting the mating portion (32) to the solder tail (36). The arms (38) are dimensioned relatively to offset the solder tails (36) with respect to the mating portions (32), in interleaved relationship to form a single row of solder tails (36) for soldering to respective contact pads arranged in a single row on a printed circuit board (20).

Abstract: The compound ortho-methoxyaniline (o-anisidine) can be polymerized by both chemical and electrochemical means to produce polyanisidine, a soluble polymer of high electrical conductivity. Also called poly-o-methoxyaniline or PANIS, polyanisidine can be further blended with various other polymers enabling construction of devices with desirable electrical, optical and physical properties. Oxidative polymerization yields have been increased to 47 percent with no apparent loss in electrical conductivity. PANIS has been blended with polystyrene, polyacrylonitrile, polyethylene oxide and poly(trimethyl hexamethylene terephthalamide) (nylon) to form free-standing, stable, flexible films and fibers having electrical resistance values dependent upon the concentration of PANIS.

Abstract: A protector module (50) includes a housing (52) having cavities (58) into which are inserted electrical components such as surge protector elements (150). A lid (60) is securable to housing (52) by hinge tabs (196) having free ends (204) which are insertable through slots (200) in embossments along side surface (198) of housing (52). Latch surfaces (210) of free ends (204) latch beneath corresponding latch surfaces (212) of end walls of slots (200). Free ends (204) extend outwardly at right angles at bends (206) so that lid (60) can remain attached to the housing and retain a vertical orientation unassisted when opened permitting access to the inside of the housing (52).
