  • Connector having a ground member obliquely extending with respect to an arrangement direction of a number of contacts
    Patent number: 6572409
    Abstract: A connector element has a plurality of contacts (23) arranged in first and second directions (A1, A2) perpendicular to each other on a predetermined plane to form a matrix. A plurality of ground members (25) extend substantially in parallel to one another in an oblique direction inclined with respect to the first and the second direction on the predetermined plane. At least one of the contacts is positioned between adjacent ones of the ground members.
    Type: Grant

  • Connector easy in wire connection and improved in transmission characteristic
    Patent number: 6500029
    Abstract: In a connector having a housing (4) and a plurality of contacts (3) held by the housing, first and second ground plates (5,9) are placed between adjacent ones of the contacts to intersect with to each other. A first contacting portion (11) is formed integral with the first ground plate and is for bringing at least one of the first and the second ground plates into contact with at least one of the contacts. The first and the second ground plates are brought into contact with to each other through a second contacting portion (12) formed integral with the second ground plate. The first contacting portion may be formed integral with the second ground plate. The second contacting portion may be formed integral with the first ground plate.

  • Connector memory for an IC memory card with a small thickness
    Patent number: 5695364
    Abstract: Preferably for use in an IC memory card, a connector member (1) is for connection to a counterpart connector and comprises a plurality of contacts (5) and an insulator block (3) insulating the contacts and used as a guide frame (30) for guiding a fitting portion of the counterpart connector with the insulator block provided with an engaging portion (33) for engaging the fitting portion when the counterpart connector is connected to the connector member. More particularly, the engaging portion comprises a beam (40) resiliently supported by each edge block wall of the guide frame and a protrusion (41) for engaging a notch formed in the fitting portion when the fitting portion is received along the guide frame.
