Abstract: A connector includes a plurality of contacts each including a first piece having a contact portion, a pressure receiving portion, and a projection inwardly extending from the pressure receiving portion; a second piece having a connection portion and a fulcrum portion; and an elastic portion for connecting the first piece and the fulcrum portion. The contact portion, elastic portion, fulcrum portion and connection portion are arranged in the form of a crank. A housing is formed with protection walls for preventing its ceiling portion from being raised. The pivoting member is mounted on the housing so that the axis of rotation is moved with its pivotal movement to achieve their compact rotation. With the construction, the connector achieves a miniaturization or reduced overall height, and a stable electrical connection with simple operation and slight operating force without any failed connection even if being subjected to undue external force.

Abstract: A card connector into and from which a memory card is detachably inserted and removed, includes contacts each adapted to contact a connection portion of the memory card, and a housing for arranging and holding the contacts and having an inserting opening for inserting the memory card. The housing includes two side walls, a rear wall, and a lower wall contiguous to these side and rear walls to form the inserting opening for the memory card by these walls. A shell is arranged on the side of the housing opposite from the lower wall, and an elastically deformable tray is arranged on the lower wall so as to be slidable with the aid of a tray restraining plate. The card connector is miniaturized and lighter, more compact and simple in construction and is easy to remove a memory card.

Abstract: An electrical connector includes a plurality of contacts having a contact portion adapted to contact the memory card and arranged above and below, and a housing for arranging and holding the contacts and having a fitting opening into which a memory card is inserted. The housing is on the side of the contacts arranged below with at least two projections located on the side of insertion of the memory card and projecting into the fitting opening, and the projections having an inducing portion at their innermost end in the inserting direction of the memory card. With the electrical connector thus constructed, a memory card can be inserted into the connector without deforming the contacts, and memory card can be prevented from swiftly dashing out of the connector by the action of contact forces of the contacts when removing the memory card from the electrical connector.

Abstract: A card connector which is able to be connected to at least two cards, includes contacts corresponding to the number of the cards, a tray in which at least two cards can be mounted, and a housing having a fitting opening for receiving the tray therein and for arranging and holding the contacts. Also, a card connector which is able to be connected to four cards, includes four kinds of contacts, a tray having card mounting sections in which four cards can be mounted, and a housing having a fitting opening for receiving the tray therein and for arranging and holding the four kinds of contacts. With these constructions, miniaturization in height or reduced overall height of connector is possible with a simple construction.

Abstract: A card connector includes a required number of contacts adapted to contact connection portions of the plurality of the memory cards, and a case arranging and holding the contacts therein and having a plurality of inserting holes for the memory cards. The connector includes at least one locking member movable or pivotally movable when a memory card is inserted, and at least one spring member displaceable when the memory card is inserted. In one aspect, a card connector includes at least one slider for forming parts of the plurality of inserting holes, and at least one holder for movably holding the slider. Consequently, the card connector is able to prevent the insertion of more than one memory card with a simple construction, to provide a miniaturized and high-density connector without any limitation of circuit board design, and easy to design its case and easy to remove the inserted card.

Abstract: A connector includes contacts having a contact portion, a connection portion, a fulcrum portion, a jointing portion and a pressure receiving portion; a housing having a ceiling portion covering the contact portions of the contacts and an upper wall covering the pressure receiving portions; and a pivoting member having an actuating portion, urging portions, anchoring holes and a cover portion. Pivotal movement of the urging portions between the connection portions and the pressure receiving portions brings the contact portions into contact with a connecting object. Gaps between the tip of the upper wall and the actuating portion and between the upper wall and the tip of the lower part of the pivoting member are made narrow so that the pivotally moving pivoting member does not touch the upper wall of the housing, thereby enhancing dust-proofing and achieving no insertion force for flexible printed circuit board.

Abstract: A connector includes a housing and a required number of pusher members. The housing has a fitting aperture into which two or at least three flexible printed circuit boards are inserted and insertion openings for holding the required number of the pusher members. When the two or at least three flexible printed circuit boards are inserted into the fitting aperture of the housing, contact portions of the two or at least three flexible printed circuit boards are urged by the pusher members so as to be connected to each other to achieve electrical continuity of the connector. With this construction, the connector can be mounted on anywhere with the exception of a flexible printed circuit board as by adhesion or pushing down by a frame of the set without using soldering, thereby permitting low cost manufacture and wide freedom of selection of connector mechanisms.

Abstract: A connector includes a plurality of contacts each having at one end a contact portion adapted to contact a connecting object, at the other end a connection portion to be connected to a substrate or the like, and between the contact and connection portions a fixed portion to be arranged and held in a housing so that the contact portion is displaceable about the fixed portion as a fulcrum in a cantilevered manner relative to the housing arranging and holding the contacts. If the thickness of the housing where the contact portions of the contacts are displaceable is not more than 0.6 to 0.7 mm, the housing is provided with a protrusion formed with a hole to permit the contact portions to be displaceable in the hole, thereby ensuring sufficient contact pressures to obtain stable connection with a mating connector without unintended deformations of the contacts.

Abstract: An electrical connector includes a housing, a substrate, and shielding plates. The housing has an inserting hole for the substrate, and the substrate has a plurality of signal patterns and a plurality of ground patterns alternately arranged on at least one surface of the substrate in a manner that one signal pattern is between two ground patterns. The signal patterns and the ground patterns each have a contact portion to contact a mating object and a connection portion to be connected to a cable. The shielding plates are each connected to the connection portion of the ground pattern for shielding. With this construction, the electrical connector achieves its miniaturization and reduction in crosstalk regardless of length of connected cables.

Abstract: A connector includes contacts each having a contact portion, an elastic portion and a fulcrum portion between the contact portion and a connection portion, and a pressure receiving portion; a housing fixing the contacts; and a slider having urging portions pivotally moved between the connection and pressure receiving portions of the contacts to urging the contact portions against the circuit board, thereby achieving reliable connection and miniaturization of the connector. In an aspect, the housing is formed on the side of a board insertion opening with a recessed portion for conducting the board. In another aspect, the contact includes upper and lower contact portions one above the other arranged alternately staggered so as to be connected to a circuit board having contact portions alternately staggered, so that no defective connection occurs, even if the circuit board is inserted erroneously upside down.

Abstract: A connector for plural kinds of cards includes a housing, and a gate-shaped slider slidable on slide rails on both sides in a card inserting space in the housing. Inserting a wider and thicker card, the card engages and moves together with the slider into the housing to contact contacts on one surface in the housing at a predetermined inserted position. Inserting a narrower and thinner card, the card enters an inner space of the gate-shaped slider, and while the slider remains stationary, the card arrives at a predetermined inserted position with the aid of a step having an inclined face in the slider, whereupon the contacting surface of the card arrives at the same level as that of the contact surface of the wider and thicker card so that the card comes into contact with the contacts to achieve an electrical connection therebetween.
