Abstract:
A method of manufacturing a ferrule (15, 70) which comprises positioning a wire (20) inside a cavity (10, 60) in a molding die (MD, MDa) for forming the ferrule, introducing plastic material in the cavity thereby forming the ferrule with the wire extending through an end of the ferrule, and withdrawing the wire from the ferrule whereby a small hole is formed in which a core of an optical fiber is to be received.
Abstract:
A circuit panel assembly for use in interconnecting electrical components (20, 21) has circuitry in the form of electrical traces (14) defined on a substrate (11). A layer of anisotropically conductive adhesive (24) surface mounts the components (20, 21) to the circuitry. Circuit panel assemblies having single (11) or multiple substrate (111, 111a, 111b, 111c) layers can be employed. The substrates can be rigid, such as metal, or can be flexible films, and a flexible dielectric coating (111a, 111b, 111c) deposited over the circuitry on one substrate layer can form the substrate for the next layer of circuitry. The anisotropic adhesive layer (24) is deposited over an entire component connecting area (15) to mechanically secure the components (20, 21) to a substrate (11), but the adhesive (24) is electrically conductive only normal to the layer so that laterally adjacent component leads are not shorted. A method for fabricating a continuous strip of flexible single and multilayer (310, 334) panel assemblies is also disclosed.
Abstract:
A modular connector includes a housing (18, 181, 191, 518) having an interior surface adapted to engage a mating external surface of one or more contact-receiving and -carrying modules (20, 210, 520, 521) supported within the housing. The wire contacts (64, 65, 66, 600) are removably supported within the module to permit one or more contacts to be removed and replaced without destruction of the entire module. Mating structures of the housing and the module and the contacts repeatably position the housing portions with respect to one another and precisely position the module within the housing laterally, longitudinally, and vertically and precisely position the contacts within the module. The invention also includes a module (520, 521) having an integral sealing boot (578) formed thereon to provide strain relief and effective sealing around the conductor wires (536, 537) entering into the module and between the module and the housing portions.
Abstract:
An electrical connector comprises a plurality of signal contacts (20, 30) disposed in two rows in an insulating housing (10) and each having one end for connection to respective signal wires (S) in an electric cable (1) and another end for connection with a signal terminal of a member to which the connector is to be connected, a plurality of ground contacts (62) disposed in a row between the two rows of signal contacts (20, 30) and having one end for connection to ground wires (G) in the cable (1) and another end for connection with a ground terminal of the member to which the connector is connected, and a shield member (60) disposed between the signal contacts to prevent crosstalk therebetween.
Abstract:
A harness making machine in which pairs of connectors (15, 15') are fed past work stations (13, 13') in which wires (25) are terminated in the connector pairs by rams (22, 22') is associated with a wire holding head (21) which defines either a curved wire feeding track (34) permitting the formation of a wire loop between the connectors of a pair or a straight wire feeding track (35) according to the position of a rotatable pilot (37) mounted in the head (21). An upper part of the track (34 or 35) is formed by a groove in the underside of a support plate (21) and the base of the track (34) is closed and opened to form and release a wire loop by the movement of cam followers (52 and 53) between outer and inner positions. Such movement is effected by lower and upper cam plates (54 and 55) connected by pins (56, 56') to pistons (78, 78').
Abstract:
Multicontact detachable sealed electrical connector (2) having two connector halves (4, 6) receiving male (10) and female (12) terminals therein is used to establish a sealed interconnection between conductors (8, 14) in one or more circuits. Conductors (8, 14) in separate circuits are separately sealed, and sealing integrity can be maintained even though less than all of the circuits are interconnected. Terminals (10, 12) are received within cavities (40, 70) in the housing (20, 50) and one housing (50) has a plurality of tubular protuberances (80) defining a cavity extension. Inner seals (62) are positioned around these protuberances and are deflected when partially received within the cavity (40) in the other housing (20) to maintain separate sealing integrity at the interface between the two connectors (4, 6).
Abstract:
Solder cup connector comprises a one piece insulative housing (52) having terminals (10) received in passages (50) extending between mating face (56) and rear face (54). Terminals (10) are stamped and formed from strip stock with a pin or socket (12) formed in one direction from the plane of the stock, a solder cup (20) formed in the opposite direction, and a transition portion (14) crossing the axis of the terminal therebetween. The transition portion (14) has laterally extending flanges (24, 26) which bend to bite into the sidewalls of the passage (50) to prevent withdrawal.
Abstract:
An electronic key assembly (80, 109, 119) comprising an insulating plug body (11, 88, 152, 230) having a front mating end (17) for receipt in a jack and a rearwardly spaced, chip carrier receiving cavity (19, 92, 114, 124, 154, 232). A series of contacts (12, 89, 90, 112, 125, 126, 179, 270) having first contact portions (34, 99, 127, 127', 180) are mounted in body recesses (33) at the mating end (17) for engagement with spring contacts of a complementary jack and second spring contact portions (36, 103, 132, 182, 272) which extend into the cavity (19, 92, 114, 124, 154, 232) are for engagement with respective leads of a chip carrier (15, 87, 111, 120, 155, 260) received therein. Releasable latch arms (41, 189, 189', 290) extend rearwardly from the mating end (17) and, in some examples, a sleeve-form shield (13, 192) moulded or latched in the fingerpiece (14) is received on the body (11, 58, 152) to surround a rear end and the chip carrier (15, 87, 111, 120, 155). Anti-overstress hooks or eyes (64, 220, 299) extending from the fingerpiece (14) hook over the latch arms (41, 189, 189', 290) to prevent excessive movement of the latch arms (41) away from the body (11). In one example, the shield (192) includes a window (194) having a rim (195) surrounding the first contact portions (180) and the fingerpiece (210) includes a tongue (213) which extends forwardly within the shield (192) to a location adjacent the first contact portions partly to close the window (194). In another example, a grounding plate (242) extends through a slot (240) in the plug body (230) into contact with a printed circuit board (260) in the cavity (232).
Abstract:
An adhesive interconnecting means (10) is comprised of one or more conductors (24) on an insulating substrate (20), a first adhesive layer (12), said first layer (12) being an anisotropically conductive adhesive (14) which is disposed over said conductors (24) and substrate (20) and a second adhesive layer (16) said second layer (16) being a flowable adhesive that extends over the anisotropically conductive adhesive layer (12). Upon positioning the first substrate conductors (24) in an overlapping conducting relationship to the second substrate (22) conductors (24) and applying pressure to the positioned areas, the second adhesive layer (16) flows from the positioned areas and exposes the anisotropically conductive layer to electrically interconnect the corresponding conductors accompanied by the adhesion of the remaining surface of the first substrate (10) to the surface of the second substrate (22). A method for interconnecting at least one conductive path means of a first insulating member with at least one conductive means on a second insulating member is also disclosed.
