  • Publication number: 20200194937
    Abstract: An inner conductor terminal for a shield connector includes a terminal connecting portion to be connected to a counterpart terminal. A base plate is provided continuously with the terminal connecting portion and has a soldering surface on which a conductor of a shield cable is placed and soldered. The shield cable includes the conductor and an insulation coating covering an outer periphery of the conductor. The conductor is exposed at a terminal portion of the shield cable. A conductor holding portion is arranged opposite to the conductor so as to be contactable with the conductor placed on the soldering surface in a direction where the conductor is separated from the soldering surface.

  • Patent number: 9226406
    Abstract: By connecting together connecting electrodes having an organic film serving as an oxidation-preventing film using a conductive adhesive, the manufacturing process can be simplified, and a highly reliable connection structure can be constructed at low cost. An electrode connection method, in which a first connecting electrode 2 and a second connecting electrode 10 are connected together through a conductive adhesive 9 that is interposed between the electrodes, includes an organic film formation step in which an organic film 6 is formed on at least a surface of the first connecting electrode, and an electrode connection step in which the first connecting electrode and the second connecting electrode are connected together through the conductive adhesive. In the electrode connection step, by allowing an organic film decomposing component mixed in the conductive adhesive to act on the organic film, the organic film is decomposed, and thus connection between the connecting electrodes is performed.

  • Patent number: 8507803
    Abstract: The invention offers a board-connecting structure that can provide electrodes with a fine pitch and that can combine the insulating property and the connection reliability. The structure of connecting printed wiring boards 10 and 20 electrically connects a plurality of first electrodes 12 and 13 provided to be adjacent to each other on a first board 11 with a plurality of second electrodes 22 and 23 provided to be adjacent to each other on a second board 21 through an adhesive 30 that contains conductive particles 31 and that has anisotropic conductivity. By heating and pressing the adhesive placed between the mutually facing first electrode 12 and second electrode 22 and between the mutually facing first electrode 13 and second electrode 23, an adhesive layer 30a is formed between the first board 11 and the second board 21 and in the adhesive layer 30a, a cavity portion 33 is formed between the first electrodes 12 and 13 and between the second electrodes 22 and 23.
