Abstract: A spring loaded shutter with locking features is used to expose host pins of an adapter to protect the pins from damage and the user from injury. The locking mechanism for the shutter releases when a card is inserted into the host adapter. Engagement of locking pins by the card releases the locking pins and frees the shutter to be pushed backward as the card is connected to the host pins. The shutter is biased in a forward position so that removal of the card from the adapter results in a return of the shutter to its forward locked position where it effectively covers the pins to protect the pins from damage and the user from injury.

Abstract: An ejector mechanism for a connector comprises a receptacle and an elastic device deformably received in the receptacle. An ejection plate is adapted to force the elastic device to deform and store tension when an external card is manually inserted into the connector and exerts a force on the ejection plate. A retaining member is movably retained in the connector for retaining the elastic device at the deformed status. A releasing device is connected to the retaining member for releasing the retention of the retaining member to the elastic device thereby causing the ejection plate to eject the card via release of the tension stored in the elastic device.

Abstract: A cable connector system for connecting a cable to an electronic component through a plug coupled to the cable and a receptacle coupled to the electronic component. The plug provides a unique structure that is easily connected to the receptacle without the use of tools. Additionally, the plug provides cover over the end of the plug to which the cable is connected so that the plug may be easily pulled past obstructions with which a conventional plug could become entangled.

Abstract: A novel surface-mount electrical component for mounting on a circuit board. The electrical component includes at least one pin and a retaining surface. The pin serves as both a point of electrical contact between the electrical component and the circuit board and as a solder-anchoring point. The retaining surface is remote from the pin and serves as an additional solder-anchoring point for restricting the movement of the electrical component on the circuit board. Both the pin and the retaining surface are coplanar, ensuring even soldering of the electrical component to the circuit board.

Abstract: In a connector block of the type including a body and at least one end cap supported on the body, the end cap housing a plurality of terminals with conductive contacts extending therefrom into the body. A conductive power bus including a rail, a plurality of fingers and a leaf-spring tail is coupled to the connector block, with the power bus positioned clear of electrical contact with the terminals or the conductive contacts. The power bus rail is seated within the connector block between the body and the end cap. The power bus fingers extend within the body from the rail and are positioned between the conductive contacts. The power bus leaf-spring tail extends external of the body. The connector block can cooperate with a suitably configured mounting bracket having a power bus and plural fingers which terminate in electrical contacts to transfer power therebetween to energize subsystems such as protector circuits that may be coupled to the connector block.

Abstract: In a conventional IC card connector, guide walls provided on side walls of a housing comprise surfaces parallel to each other, and an interval between the guide walls is somewhat greater than a maximum width of a standard of the IC card. If the IC card having the width less than the maximum value of the standard is used, the IC card is greatly slanted due to a large amount of play, and an operation member of a detection switch cannot be operated by the IC card. In an IC card connector of the present embodiment, if the width of the IC card is small, the IC card is supported at sides by vertical surfaces, thus the movement of the IC card in the widthwise direction is regulated. If the width of the IC card is large, the IC card is supported at the side by a slope, thus the movement of the IC card is regulated.

Abstract: An IC card connector device solves a problem with a conventional IC card connector device using two IC cards, the problem being such that two push rods are vertically disposed, leading to higher cost due to more parts incorporated, poor assemblability, and an increased height of the connector device. To eject a first IC card, which has been inserted, a single push rod set in an extended position is pushed to eject the first IC card via a single transmitting pin. To eject a second IC card, a handle is circularly moved with the push rod in the extended position so as to move the transmitting pin from a first heart-shaped cam cutout to a second heart-shaped cam cutout. In this state, the push rod is pressed toward a pushed-in position, which causes the single transmitting pin to circularly move to eject the second IC card.

The second housing defines a plurality of passageways for receiving contacts therein and has a second engaging portion at each end thereof for detachably engaging with the first engaging portion of the first housing. The detachable second housing allows replacement of contacts therein for adjusting to different capacities of memory modules.

Abstract: An IC card connector device in which an IC card ejecting operation and a misoperation canceling operation are selectively performed. A frame for guiding an IC card at insertion and extraction is provided with a circulation cam groove and a clearance groove with which a second transmission pin pivotally supported by a pushrod is selectively engaged. By pushing the pushrod after projecting it to a first projecting, a drive plate that is placed in the circulation cam groove is pushed via the second transmission pin, thereby ejecting the IC card. When a misoperation occurs, the second transmission pin is caused to trace the clearance groove, by pulling the pushrod frontward and then pushing the pushrod, thereby canceling an IC card ejecting operation. Furthermore, a handle (actuating element) of the pushrod is provided with a heartshaped cam groove with which a first transmission pin pivotally supported on the frame is engaged.
