摘要:
An apparatus (11) for stripping cable (12) to remove a section of cable jacket (13) includes opposed stripping blades (15) each having a pair of adjacent blade sections (18) including semi-circular cutting edges (19) defined by grooves (20) operable to cut the jacket (13) peripherally with the adjacent blade sections (18) driven axially apart in a relative sense to pull the cut section of the jacket away from the cable. Pairs of guide and gripping members (16) having internesting teeth (23, 24) are positioned adjacent the blade sections (18) to grip the cable (12) and provide a support for the cable. A suction device (17) is displaced axially to receive the cut jacket section and remove such from the stripping site.

A method and product for providing an electrical interconnection between components and a substrate includes the use of an adhesive coating. The coating (40,42) is applied between the contacts (14,22) of component and substrate and the surface of a conductive fiber-filled, elastomeric connector (30) and is operable to bond the contacts to the surfaces of the connector with conductive fibers (34) of the connector piercing the adhesive coating to provide multiple contacts (36,38) and define current paths for the interconnection while mechanically bonding connectors, components, and substrate together. Protective covers (44) are applied to connectors to protect the adhesive coatings prior to use with sheets (50) or rolls (52) alternatively used to carry arrays of connectors in patterns corresponding to substrate contacts (14,22).

An impedance controlled elastomeric connector (10) includes signal contacts (30) and ground contacts (40) with leads (32, 42) and a ground plane (25) formed of conductive foil (24) laminated to a dielectric and insulating film (18) folded around an elastomeric core (12) with the signal, ground spacing and the dielectric constant and thickness of the film selected to provide controlled impedance signal paths through the connector as compressed between components (2, 6).
摘要:
A duplex fiber optic connector assembly enables mating the fibers of a first multifiber cable with like fibers of a second cable or cables with maximum axial alignment of the respective fiber paris. An interconnect member receives cable terminating connectors in opposite sides thereof. Each connector carries the fibers of a respective cable in individual ferrules, each ferrule having limited floating mount within the respective connector. The mating pairs of ferrules are received in opposite ends of receptor members each of which has an axially profiled bore adapted to receive the respective ferrules and a profiled outer surface which allows movement about the geometric center of the receptor so as to axially align the bores of the ferrules received therein. Connectors at each end of a predetermined length of fiber optic cable provide a fiber optic extension cord, analogous to the well-known electrical extension cord, for convenient and efficient interconnection between optical signal-using equipments. Small interconnect members receive the connectors of such fiber optic extension cords to allow even wider-ranging interconnections. Wall boxes containing such interconnect members, connected to permanently installed fiber optic cables conveying optical signals from a central optical signal source, allow a user to readily access optical signals by "plugging-in" a connector therein.
摘要:
A method of manufacturing a guide plate for use in a chip carrier socket or other electrical connector provides the precision required for close-center line spacing while minimizing the cost associated with production. A block of ceramic or the like is ground to the precise outside dimensions required. Grooves are then cut in the block of ceramic, and the ceramic is then sliced into respective guide plates. The guide plates are inserted into openings provided in the electrical connector an retained therein. The grooves are dimensioned to cooperate with contact pins of the electrical connector to precisely maintain the pins in position, whereby when a chip is positioned in the electrical connector, the pins will be in position to make an electrical connection with the pads of the chip.

An unkeyed insert (4) removably retained in a electrical connector (2) has a mating portion (44) projecting from a forward face of the connector beside a mating structure (12) also projecting from the forward face of the connector (2). The mating part (44) defines a socket (60) for receiving a screw lock (234) on a mating connector (200). The mating part (44) has an open side (58) closely adjacent to the mating structure (12). By virtue of its rectangular shape, the mating part (44) can only be angularly oriented with its open side facing the mating structure (12). The unkeyed insert (4) cannot be mated with a keyed structure (218) of the mating connector (200) since an end face (62) of the mating part (44) would butt against the distal end of a rib (222) of the keyed structure (218).

A miniature socket (10) for electrically interconnecting contact pads on a bare integrated circuit chip (16) to circuit pads (64) on a substrate (18) is disclosed. The socket includes a housing (12) and contact elements (14) having a diameter of about 0.003 inches. The housing (12) includes a recess (28) on one surface (30) for receiving the circuit chip (16) and cavities (44) on an opposite surface (38) for receiving the contact elements (14) and passages (56) leading to the recess (28) from the cavities (44) for receiving the pin sections (80) on the elements (14). Methods of forming a gold tip (84) on the pin sections (80) and for providing cavities (44) and passages (56) in the housing (12) are also disclosed.

A self-aligning optical receptacle cover (10) suitable for use with various types of optical receptacles (20). The cover (10) seals the receptacle (20) against dust and debris, and alignment pylons (16, 18) extending from receptacle cover (10) cooperate with active optical devices (30, 40) to maintain precise alignment thereof within the receptacle during manufacturing operations.

A card reader (2) especially for use in connecting gold plated pads on a subscribers identity module card (4) to respective tin plated pads on a printed circuit board (6) in a car telephone handset, comprises an insulating frame (8) having spigots (26) for fixing it to the circuit board 96), and a metal cover (12). A bar (22) spanning the frame (8) supports contact elements (10) molded thereinto. Each contact element (10) has a 10 contact spring (40) provided with a bowed, gold plated contact surface (5) near its free end for engaging a respective gold plated pad on the card (4), and intermediate its ends, an oppositely bowed, tin plated, contact surface (44) for engaging a respective tin plated pad on the circuit board 96). With the card (4) resting on a ledge (18) in the frame (8), the metal cover (12) is latched to the frame (8) to force the contact surfaces (44 and 50) against their respective pads. The contact springs (40) are so configured that the contact forces (F1 and F2) applied by, and the length of wipe of, the contact surfaces (44 and 50) is appropriate to the plating thereon and the plating on the pads engaged thereby.
摘要:
In accordance with the present invention, a heater element which includes a layer of ferromagnetic material is included in a connecting device along with a fusible material such as a solder preform. The connecting device includes, for example, a hollow sleeve formed of heat shrinkable material. The solder preform, the heater element and the heat shrinkable hollow sleeve are integrally formed as a self-contained solder sleeve device such that the heater element is separate from the objects to be joined and does not completely shield to generation of a inductive current in the objects to be joined. The connecting device thus promotes even flow and bonding of the fusible material around a junction between the objects. Further, a connecting device is provided which permits visual inspection of a connection between objects bonded upon activation of the connecting device, thus providing an opportunity to confirm the integrity of the junction.
