  • Patent number: 5009607
    Abstract: A flexible circuit connector is presented which is used to electrically and mechanically connect a flexible circuit to a circuit board or other electronic device. The connector also functions to wipe off any residue or debris on the electrical contacts before final connection. The connector is comprised of a male plug and a female adapter. The male plug comprises two interlocking pieces including a block and a cover. These two pieces allow for easy assembly and disassembly of the plug in conjunction with a flexible circuit. The female adapter comprises a hood which may be fastened directly to a circuit board. Alternatively, the hood may be fastened to a base plate which has gold plated contacts and conductive pins which pass through and which are soldered to the circuit board.

  • Patent number: 4971575
    Abstract: A high-density connector arrangement for flat multiconductor cables has a support housing, and flat cable support members held by the support housing. The cable supports may be organized in banks for increasing density of conductors, and are preferably releasably secured to the support housing. Contact between conductors on mating cable supports of two connectors is enhanced by providing resiliency of engagement, by causing the cable to arc outward or partially splitting the supports or providing a resilient layer arranged between the cable tape and its support.

  • Patent number: 4908336
    Abstract: A flexible circuit (1) provided with at least one connector for connecting an electrical component (25) to corresponding conductors of the flexible circuit. The connector consists of two parallel contact strips (5) from insulating flexible material, which are attached to the flexible circuit. The surfaces of the contact strips (5) facing each other have contact surfaces (6, 7) which are electrically connected to the corresponding conductors (3, 2) of the flexible circuit (1). The connector further consists of a positioning block (15) from insulating material, which is provided with holes into which the connecting pins (21, 22) of the electrical component (25) can be inserted. Grooves (16, 17) in which the contact strips lie are provided in the side faces, adjacent to the holes, of the positioning block and have a depth which is greater than the minimum distance between the wall of a hole and the adjacent side face of the positioning block.

  • Patent number: 4824384
    Abstract: A connector adapted to couple stripped electrically conductive wires of a flat cable with the traces of a printed circuit board through a mating connector upstanding from the printed circuit board. The connector comprises a housing formed with a longitudinal central slot adapted to receive an electrically conductive ground bus. The upper end of the bus is adapted to retain stripped ground wires of the flat cable by crimping and soldering. The lower end of the bus is adapted to be received within the mating connector. A plurality of parallel apertures are formed in the housing on opposite sides of the bus to receive signal contact, the upper ends of which are adapted to retain stripped signal wires of the flat cable by soldering. The lower ends of the signal contacts are adapted to be received within the mating connector.

  • Patent number: 4824397
    Abstract: The present invention relates to an electrical connecting device in which the cable is made from a flexible wiring substrate, bent into a U-shaped configuration at a prescribed location, and inserted into the space between the connector terminals. Because of this construction each spacing of terminals contained in each of the respective rows of terminal groups becomes very narrow, and the cable and connector can be reliably joined an electrically connected at the terminal.

  • Patent number: 4815990
    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).

  • Patent number: 4808773
    Abstract: A cable for use in ultra-low impedance electrical interconnections and a connector for optional use therewith. A two-conductor version of the cable is formed, for example, by the steps of, disposing an elongated first strip of electrical conductor on an elongated first strip of electrical insulator; disposing an elongated second strip of electrical insulator on the first strip of electrical conductor; disposing an elongated second strip of electrical conductor on the second strip of electrical insulator; and, winding the strips in combination from one side to the other to form the cable as a spiral in cross section. The electrical conductors can comprise elongated rectangular sheets of metal foil or, alternatively to provide a cable of increased flexibility, a plurality of wires disposed side-by-side along the length of the associated strip of electrical insulator.

  • Patent number: 4802866
    Abstract: A two-piece solderless connector is disclosed herein having a first member formed with a cavity supporting a leaf spring over which a strip of plastic backed electrical conductors are carried so that the strip is folded over upon itself to define a contact closure between opposing surfaces of electrical conductors. Opposite ends of the conductors within the cavity terminate at an elongated opening constituting an entrance leading into the cavity for insertably receiving similar electrical conductors projecting from a second member of the connector. Resilient biasing members urge the conductors together. The connector conductors of both the first and second members provide an integral part of a flex circuit and the electrical conductors of each member are integral with separate and individual circuit conductors included in the over-all flex circuit.

  • Patent number: 4718863
    Abstract: A flat multiconductor jumper cable comprises a plurality of elongate substantially parallel and transversely spaced conductors surrounded by a casing of insulation. At one or both ends of the jumper cable, exposed portions of the conductors are formed in a curved clipped portion for solder connection to an integrated circuit substrate. The conductors are preferably formed of a soft non-resilient material such as copper and the clip portion is provided to have a substantially circular cross-section. The clip portion, formed in a generally U-shaped configuration defines a pocket for receipt therein of the edge of a substrate having conductive pads on opposing surfaces. Upon soldering the clip portion to the conductive pads, solder fillets are formed in such a manner as to provide an enhanced electrical and mechanical joint.
