  • Patent number: 7997913
    Abstract: A card connector includes a housing having a receptacle to receive therein a card in an insertion direction and the card has a terminal member. A connection terminal is secured to the housing and is configured to contact the terminal member of the card. A card ejecting action detecting switch is configured to detect when the card is ejected from the housing. A card guide mechanism is provided with an urging member for urging the card in a direction opposite the insertion direction. The card guide mechanism is configured to hold the card at a locked position to ensure that the terminal member of the card is in contact with the connection terminal and to permit movement of the card in the opposite direction by a pushing force exerted on the card in the insertion direction. The card guide mechanism ejects the card after performing a pushing action on the card a plurality of times.

  • Patent number: 7794281
    Abstract: A card connector is configured for receiving a generally rectangular card therein. The card has contact pads and generally parallel first and second sides with a cut-away portion formed in the first side in proximity to a front end of the card. The cut-away portion includes a short length extending from the front end generally parallel to the first side, and a tapered shoulder part extending from the short length to the first side. The connector includes an insulative housing with first and second spaced apart sidewalls that define a cavity therein for receiving the card in an insertion direction. A tapered surface is provided adjacent the first sidewall to guide an improperly inserted card at an angle to the insertion direction and a second sidewall recess is formed in the second sidewall to permit entrance of a corner part of such improperly inserted card.

  • Patent number: 6984135
    Abstract: A press fit pin of the present invention has a press-fitted region to be press-fitted and connected to a conductive through hole of a printed circuit board or other circuit substrate. The press-fitted region is formed into substantially an M-shape in cross-section, which has two beam-like regions extending substantially in parallel, and a connection region connecting the beam-like regions in a deformable manner. The connection region is formed into such an arcuate shape in cross-section that an upper surface corresponding to a valley side of the M-shape is a concave surface and an opposite lower surface is a convex surface. A part of the upper surface is partially located on the lower surface side with respect to a straight line L connecting left and right inner side continuous portions where the lower surface of the connection region and inner surfaces of the two beam-like regions are continuous to each other.

  • Patent number: 6875057
    Abstract: A memory card connector includes a housing (12) mounting a plurality of terminals (18) having contact portions for engaging contacts on one side of a memory card. A cover (14) is mounted on the housing (12) and defines a card-receiving cavity (16) therebetween for receiving the card in a given, normal orientation. A displacement portion (22) of the housing displaces the memory card toward the cover if the memory card is inserted into the cavity in an abnormal orientation. A stop (44) on the cover engages an edge of the memory card to prevent the card from reaching the contact portions of the terminals if the memory card is inserted into the cavity in the abnormal orientation.

  • Patent number: 5669787
    Abstract: A miniaturized shunt connector assembly provides sufficient retention force between the assembly and mating contact posts and includes an insulative housing defining a contact-receiving cavity and a contact mounted therewithin. The contact includes an opposing pair of generally opposing support pieces including parallel arm supporting portions spaced a given dimension apart. Resilient contact arms extend from an upper edge of each arm supporting portion and are inwardly and downwardly formed to project beyond the lower edge thereof. An anchor portion extends from a lower portion of each support piece and connects to an adjacent portion of the other of the pair of support pieces. One resilient contact arm opposes a corresponding resilient contact arm inside respective arm supporting portions and maintains a spaced apart dimension smaller than the dimension of the parallel arm supporting portions.

  • Patent number: 5655917
    Abstract: A card-receiving connector system for a miniature circuit card. A card holder receives a card, and a frame is adapted for locating the card holder in an operative position thereon and includes spring contacts mounted therein for engagement with electronic circuitry on the card. Complementary interengaging latches are provided between the frame and the card holder for holding the card holder in the operative position. An eject mechanism is mounted on the frame for ejecting the card holder from its operative position. An unlatching mechanism is operatively associated with the eject mechanism for unlatching the interengaging latches in response to movement of the eject mechanism. Lost motion is built into the eject mechanism to permit unlatching of the latches prior to ejecting the card holder from its operative position.
