Abstract:
A flexible cable connector has an insulating housing with cable receiving cavities opening at respective mouths to respective opposite faces of the housing. Rows of electrical contacts are mounted in respective cavities and first and second, cable clamping sliders are latched by locking arms on opposite ends thereof to respective opposite ends of the housing with central cable pressing portions entering respective mouths. The locking arms on the same slider are offset to extend in different levels or planes so that the arms can move past each other along the end of the housing in a cable insertion direction from a cable admitting to a cable clamping position without interfering with each other.
Abstract:
This invention provides a high-density planar contact array capable of interconnecting various electronic devices using a pad to pad approach or pad to pin, which is capable of accommodating non-coplanarity in the Z axis of printed circuit boards but which still maintains good electrical contact.The array comprises an insulative substrate sheet that has a plurality of parallel conductive lines terminating in a pad over a hole in the substrate.
Abstract:
An electrical connector (1,1') having multiple contacts (40') are arranged in the insulating housing (10) at a predetermined pitch and have a J-shaped connecting section (44). When an external force (F), which tends to pull a flat cable (4) in a direction away from connector (1) is applied to the flat cable (4), connecting sections (44) of all contacts (40) are bent and their back surfaces (56) are pressed against the inner wall (30) of the insulating housing (10). This pressure generates resistance from the inner wall (30) resulting in a strong frictional force between connecting sections (44) and flat cable (4), thus reliably securing cable (4) in the connector housing.
Abstract:
A connector comprises a plurality of forked terminals, an insulating housing, a flat cable and a slide member. The terminals are inserted into the housing from an opening disposed at one side of slit-shaped through-openings arranged in parallel with each other. The flat cable and the slide member are inserted into the housing from an opening disposed at the other side of the through-openings. A pressing portion projecting from a base plate portion of the slide member presses the flat cable against the terminals. The area of a contact portion of each terminal is great to secure the connection between conductors of the flat cable and the terminals.
Abstract:
Disclosed are a circuit and method for providing automatic termination for a small computer systems interface ("SCSI") bus. The circuit resides within a bus controller comprising (1) a control circuit for controlling transmission of data on a bus and for providing an interface between the bus and a computer system for communication of the data therebetween and (2) a first bus port and a second bus port, each of the first and second bus ports permitting a device to be coupled thereto for communication with the control circuit via the bus, the bus controller being at an end of the bus when a single one of the first and second bus ports is coupled to a device and being in a middle of the bus when both the first and second bus ports are coupled to devices. The circuit of the present invention is coupled to the first and second bus ports and is capable of coupling a terminating circuit to the bus as a function of a presence of devices coupled to the first and second bus ports, the bus requiring coupling of the terminating circuit when the bus controller is at the end of the bus.
Abstract:
A method and apparatus for connecting, in an intermediate place and without cutting it, to a coaxial cable wherein an oblong section of the outer insulation is sliced out and the outer conductor is moved away discovering the inner insulation. The central conductor is connected with an electrical conductor which has one end forked, adapted to penetrate the inner insulation. The other end has a tubular shape, adapted for the insertion of the central contact of a coaxial connector, and it is insulated in it's outside surface to avoid electrical contact with a second part which provides the electrical connection of the outer conductor. The second part is a tubular metallic housing, externally threaded to screw into a standard coaxial connector, one end has a constriction, reducing the internal and external diameter, with the purpose to facilitate the insertion in the coaxial connector and to provide an internal shoulder that holds the insulated central conductor. The other end has two projecting pins diametrically opposed, adapted to penetrate the external insulation and electrically contact the outer conductor of the coaxial cable. A plastic jacket with self locking borders keeps the coaxial cable securely attached to the electrical contacts.
Abstract:
The present invention relates to an integrated outlet that allows supply of AC power to an outlet receptacle when certain conditions are satisfied. The integrated outlet contains separate modules establish electrical connection with electrical conductors that transmit AC and DC power, telecommunications, control communications, and signals transmitted along a coaxial wire. In a preferred embodiment, these electrical conductors are all disposed on a single ribbon cable. Each module within the integrated outlet can attach to only certain conductors to increase safety in the resulting system.
Abstract:
An electrical connector comprising: a terminal including a contact piece; a housing; a slider including a pressing portion; a flexible cable including an end conductor; and a reinforcing plate having a pressed face to be pressed by a pressing face of the pressing portion of the slider; wherein after the slider has been temporarily engaged with the housing in which the terminal is accommodated, the end conductor of the flexible cable is inserted together with the reinforcing plate into the housing and then, the slider is displaced to a full engaging position such that the end conductor of the flexible cable is brought into pressing contact with the contact piece of the terminal through the reinforcing plate by the pressing portion of the slider; wherein the pressed face of the reinforcing plate is formed obliquely such that the reinforcing plate becomes thinner from a front edge of the reinforcing plate towards a rear edge of the reinforcing plate, while the pressing face of the pressing portion of the slider is formed obliquely such that the slider becomes thicker from a front edge of the slider towards a rear edge of the slider.
Abstract:
A flexible circuit having termination features incorporated as an integral part thereof and a method of making the same is presented. In accordance with the manufacturing process of the present invention, the end portion of a flexible circuit of standard construction (i.e., conductive traces sandwiched between a flexible base substrate and a flexible cover film) is folded back on itself, frequently with a spacer captured in the fold, and adhesively laminated together. This laminated assembly has a thickness equal to that required for formation of reliable connector pins. Next, a small section of this folded end portion has at least the outer non-conductive cover film removed, preferably by laser techniques, to expose a plurality of connector pins or fingers. The connector fingers will have the desired thickness, width and shape to allow for direct insertion into a mating component (i.e., through-holes on a rigid or flexible circuit board; or into a receptacle such as a female connector). The fingers are preferably solder coated to allow the flexible circuit of the present invention to be attached using common solder reflow techniques.
Abstract:
In the disclosed electrical connector, the card inserted from the inlet is moved, together with the slider abutting against this card, in a state being inclined to the specified placing plane, resisting the thrusting force to the inlet side by the thrusting means, and when this card and slider reach the specified position, the card and slider are oscillated about the oscillating fulcrum part to position them on the specified placing plane, thereby causing the contact formed on the contact piece part of the conductor piece to contact elastically with the contact of the card, while fixed the slider on the specified placing plane by the lock mechanism.
