  • Patent number: 5030140
    Abstract: The electrical connector in accordance with the present invention may be distributed with the shield frame thereof temporarily mounted on the connector body thereof. While the shield frame is temporarily mounted, a portion of the connector body is restrained between engagement pawls or projections formed on the shield frame. While the shield frame is temporarily mounted, the shield frame is backed up by the connector body, thus preventing the shield frame from being readily deformed. When the shield frame is pushed to the connector body with a force sufficient to resiliently deform the engagement pawls on the shield frame, the shield frame may be moved from a temporary-fitting position to a final-fitting position.

  • Patent number: 5017156
    Abstract: The present invention relates to an electrical connector comprising a shielding frame having a casing portion, a U-shaped portion and a flat-plate portion which are integrally formed. The casing portion covers the contacts of contact pieces. The U-shaped portion covers the top surface and left-hand and right-hand lateral sides of the main body of a contact piece supporting member which houses the terminal portions of the contact pieces. The flat-plate portion covers the back side of the main body of the contact piece supporting member. Accordingly, the frame substantially perfectly surrounds the contact pieces, thus producing a shielding effect. Except for the bottom of the connector, the contact pieces may be generally surrounded by merely turning the flat-plate portion at the boundary thereof with respect to the U-shaped portion, after the contact piece supporting member assembled with the contact pieces has been assembled with the U-shaped portion and the casing portion.

  • Patent number: 5006080
    Abstract: The electrical connector in accordance with the present invention may be connected to, for example, other connector mounted on a circuit board of a machine. This electrical connector is provided at one end of the housing thereof with a board connection space into or from which a circuit board incorporated in a game cassette or the like may be inserted or removed. This electrical connector is provided at the other end of the housing thereof with a connector connection portion into or from which said other connector is adapted to be inserted or removed. Thin plate-like contact members extending over the board connection space and the connector connection portion are inserted from the side of the connector connection portion into the housing of this electrical connector. The contact members are provided at the base ends thereof with transversely turned projecting pieces. By applying a punch to the projecting pieces, the contact members may be readily pushed into the housing without the contact members damaged.
