Abstract: An electrical connector (1) comprises an insulative housing (2) defining a number of passageways (220), and a number of contacts (3) received in the passageways. Each contact has different widths along longitudinal axis thereof for adjusting its own impedance. The housing includes a number of inwardly extending channels (224) communicating with corresponding passageways, a number of slots (222) between adjacent passageways and a number of cavities (206) each communicating with a corresponding passageway to respectively define a first clearance (226), a second clearance (208) and a third clearance (228) between each contact and the housing for adjusting the impedance of the contact.

Abstract: The invention provides a compact configuration for an electrical connector having a fitting detecting function. A housing groove 25 of a female housing 20 is provided with a locking arm 26 and a detecting member 35. The locking arm 26 bends while two housings 10 and 20 are being fitted together, then returns to its original position after the two housings 10 and 20 have reached a correct fitting state and engages with a protrusion 16 of the male housing 10. The detecting member 35 is capable of being inserted from a temporary attaching position to a main attaching position. When the locking arm 26, while in a bent state, makes contact with the detecting member 35 and thereby prevents its insertion, this allows detection of the fact that the two housings 10 and 20 have not been correctly fitted together. A retaining rod 42 is provided in the center of an anterior face of the detecting member 35, and a pair of contacting rods are provided on both sides of the retaining rod 42.

Abstract: The connection plug (1) has two pins (4, 5) of the jack type, one of the pins having two coaxial conductors (42, 44) and the second having three coaxial conductors (52, 55, 57), said connecting plug comprising two distinct parts (2, 3), each of said parts supporting one of said pins, said distinct parts having members intended for their connection/disconnection and means for their electrical connection, whereby said connection plug can be converted into a connection plug for stereophonic headphones with a single pin.

Abstract: A contact (1) for an electrical connector includes an elongated body portion (12) and a board-engaging structure (10) extending downward from a lower end of the body portion. The board-engaging structure includes a tail portion (14) which defines a vertical hole (19), enabling each of two sides of the tail portion to elastically deform when the contact is inserted into a hole (32) of a printed circuit board (30). Each of the two sides of the tail portion forms a locking arm (18) curved clockwise around the girth of the tail portion. Each locking arm has a contact surface (18a) of an outer limit thereof. Each contact surface is oblique such that an upper portion thereof extends further away from a longitudinal axis of the tail portion than a lower portion thereof does. Thus a considerable contact area is created between each contact surface and an inner wall of the hole in the printed circuit board.

Abstract: An electrical appliance such as a lamp (1) includes attachment means adapted for mounting on a member (50) of the grid of a suspended ceiling. The attachment is in the form of a clip (5) which, in common with the preferably PTFE-coated wires (11) of the lamp, is thin enough to pass between the flange (52) of the ceiling member and the ceiling panels. This avoids having to drill into the ceiling grid and allows flexibility in the positioning of the lamp.

Abstract: An interconnection system comprises a circuit board having signal conductors for carrying electrical signals. The circuit board includes a plurality of contact pads coupled to each one of said signal conductors. An elastomeric compression interconnect is releasably disposed next to the contact pads of the circuit board. The elastomeric compression interconnect includes a composite material having magnetic, electrically conductive substantially spherical particles disposed in a nonconductive matrix material adapted to align into mutually isolated conductive chains. A radio frequency flex circuit is also releasably disposed next to the elastomeric compression interconnect. The flex circuit is made of a dielectric material and a bonding material exhibiting substantially low signal loss.

Abstract: Disclosed is an improved two-piece SIM card-receiving connector comprising a housing having terminals mounted therein, and a card holder having a card-receiving section for receiving the SIM card. The card holder is slidably mounted to the housing by way of ledges formed on side edges of the card holder guided within channels formed along both sides of the housing. The housing includes a lock lever having a latch projection extending therefrom. The latch projection engages a corresponding recess formed on the card holder to lock the card holder and housing in an assembled condition. The two-piece construction allows the housing to be easily and automatically assembled to an underlying circuit board, and the sliding assembly of the card holder to the housing provides "self-cleaning" of the terminals during both assembly and removal of the card holder to the housing.

Abstract: A multi-polar connectors of a wire harness on a body side which is mounted on a dash board of a motor vehicle, and the multipolar connectors of a wire harness on a panel side which is mounted on an instrument panel, have through-holes through which guiding insertion bolts extended from the dash board are passed, so that those multipolar connectors of the two wire harnesses are engaged with each other simultaneously when the instrument panel is joined to the dash board.

Abstract: A card edge connector includes inner housings that accommodate electrically conducting terminals. The inner housings are rotatably supported within a box-like outer housing. A rotatable range is regulated by projected portions of the respective housings being abutted against each other, so that an opening of the outer housing is kept open to allow an end portion of a printed board to be inserted. In addition, the terminals do not come in contact with each other, so that the circuit is kept from being shorted. When the insertion of the end portion into the outer housing is started, the upper inner housing rides over the end portion slightly. However, as the end portion is further inserted to the depth of the outer housing, introducing cams formed on a hood enclosing the end portion cause the upper inner housing to rotate with a slight insertion force, thereby causing the terminals to be urged into full engagement with the end portion of the printed board.

Abstract: A communication cable used to connect a peripheral device to a computer has a first cable, a second cable and a patch unit. The first cable encloses a set of power lines and a set of data lines, and the second cable encloses a set of data lines. The patch unit includes a socket with first and second contacts. In the patch unit, the sets of data lines of the first and second cables are connected. One of the power lines is connected to the first contact, and another of the power lines is connected to the second contact. The first cable connects the patch unit with the peripheral device, and the second cable connects the patch unit with the computer. When power is applied from an external source to the first and second contacts, the power is supplied from the first and second contacts to the peripheral device.

Abstract: A spark plug cap includes a metal connection member for electrically connecting a spark plug to a high-voltage cord and a tubular rubber body fitted on an end of the high-voltage cord and on an insulating portion of the spark plug to seal the end and the insulating portion. A core member is mounted within the rubber body surrounding the metal connection member, and the core member has a through hole. The through hole places a space, formed between the spark plug and the rubber body, in communication with a contact surface between the core member and the rubber body. Even if the rigidity of the rubber body is increased, this construction eliminates the possibility that the plug cap will be lifted or displaced relative to the spark plug by air compressed within the plug cap when the plug cap is attached to the spark plug.
