  • Patent number: 5740007
    Abstract: A CDM simulator for use with an integrated circuit having a terminal and for use with a grounding conductor, includes a cylindrical conductor, and a mercury lead switch contained in the cylindrical conductor, the mercury lead switch having a first end connected to the cylindrical conductor and a second end for connection to the terminal of the integrated circuit, and the mercury lead switch having a first length, the cylindrical conductor having an end closer to the terminal of the integrated circuit for connection to the grounding conductor in order to release electric charge from the integrated circuit to the grounding conductor, and the cylindrical conductor having a second length longer than the first length of the mercury lead switch.

  • Patent number: 5738532
    Abstract: A pin contact of a connector and a method of fabricating the pin contact which enables a substantial decrease of manufacturing cost, and smooth installation of the pin connector without a change in the pitch of arrangement at the time of press-fitting into a pin housing. A flat metal sheet undergoes blanking and pressing to form a narrow piece including a strip portion of decreased area of a fracture. Then an approximately L-shaped connecting portion is bent at right angles to raise the narrow piece sideways. Thereafter the strip portion of the narrow piece is pressed along the direction of rising, to thereby form an approximately cylindrical contact section. A raised piece at the rear of the contact section is provided with a locking section which faces approximately at right angles with the direction of arrangement.

  • Patent number: 5725385
    Abstract: A PC card connector in which a plurality of pin contacts are secured in a pin housing in a predetermined arrangement such that each of the plurality of pin contacts has a long and narrow terminal end protruding out from the pin housing. The front end portion of each terminal end is soldered onto a mounting surface of a printed board. The PC card connector includes first and second pin holders secured to the pin housing such that bottom surfaces of the pin holders are positioned opposite the mounting surface of the printed board, each of the first and second pin holders having a number of parallel guide grooves for receiving the terminal ends of the plurality of pin contacts.

  • Patent number: 5692913
    Abstract: A PC card wherein a housing of a socket connector is provided with a guide boss and a stopper protruding on the circuit board side, and with a cutout for fitting the guide boss in the circuit board. In this cutout the guide boss is fitted to position the socket connector in the direction of x. And the forward end of this stopper is held in contact with the circuit board to position in the direction of y, thus facilitating positioning of a socket connector in relation to a circuit board without a fear of socket connector displacement in subsequent processes.
