A compact card connector having reduced width and thickness is provided for receiving an information card whereby the information card has a narrow step-like recess along one of its side edges and a sliding identifier mechanism provided in a concave cut in the step. The card connector includes a frame that receives the information card, and an identifier detecting means for detecting a sliding position of the identifier. The identifier detecting means includes a suitably placed fixed contact member and a movable contact member which are mounted on the frame, with part of the movable contact member forming a projection for detecting the sliding position of the identifier, whereby the projection lies in an area within the housing space through which the step-like recess of the card is to pass. As the information card is inserted into the housing space, the projection touches an upper surface of the step-like recess and/or that of the identifier and works in the concave cut in the step.

Card connector for receiving information card with identifier therein

According to the present invention, provided is a card connector device in which supporting positions of the individual connection terminals with respect to a header are formed on a straight line without being shifted forward and backward and rigidity of the respective supporting portions of the individual connection terminals increases as the length to the contact portion increases, so that the contact pressure of the respective connection terminals is uniform and the miniaturization of the whole connector device can be accomplished. The card connector device comprises a header provided side by side with a plurality of connection terminals made of electrically conductive metal plate; and a frame, at one end of which the header is arranged and into which is fitted a card with a plurality of contacts capable of being connected to the connection terminals, wherein the connection terminals are provided with a supporting portion supported by the header and a contact portion elastically contacted with the corresponding contact of the card at a free end extended from the supporting portion, and wherein the connection terminals are formed so that the supporting portions are positioned side by side on a same straight line having a direction perpendicular to a card-inserting direction. The length from the supporting portions to the contact portions differs and, at the same time, as the length from the supporting portion to the contact portion increases, rigidity of the supporting portion increases.

The card connector device includes a header, the header having a plurality of contact pieces to be contacted with contacts of an IC card, a frame provided with a card receptacle portion contiguous to the header, and an electrically conductive cover member attached to the frame so as to cover the receptacle portion, the frame being formed with a switch portion which is operated with insertion and ejection of the card. The switch portion includes a contact plate which is pushed outwards with insertion of the card and a part of the cover member which is brought into abutment against the contact plate, the contact plate being brought into and out of contact with the cover member with insertion and ejection of the card.

Card connector device

The present invention provides a card connector capable of preventing contact parts of connector terminals from coming off card contact terminal parts due to overstroke after the contact parts contact the card contact terminal parts when the card is mounted. A housing 1 is disposed with a first contact part and a second contact part which are different from each other in placement position in an insertion direction of a card, correspondingly to one contact terminal part disposed in the card, and when the card is inserted or ejected, as long as the card is further subjected to overstroke in the insertion direction from a card mounting position, at least one of the first contact part and the second contact part is formed so as to always contact one contact terminal part.

An IC card connector having a housing provided with terminals, a frame attached to the housing, and an ejecting lever supported on the frame. The frame is a flat plate provided with a pair of mounting holes, and a connecting portion recessed in the direction of plate thickness between the mounting holes. The ejecting lever has a raised portion at the central part, jutting out in the direction of plate thickness, and inserted through from one mounting hole into the other mounting hole astride the connecting portion. The connecting portion is overlapped on the raised portion, so that the surface of the raised portion will be approximately flush with the surface of the flat plate of the frame, and the back side of the connecting portion will be approximately flush with the back side of the ejecting lever. The ejecting lever is also rotatably supported between the connecting portion and the raised portion, thereby pushing with the ejecting lever to drive out an IC card off terminals of the housing.

IC card connector having card ejecting function

A connector device in which a push rod can be locked in a predetermined approach position when an IC card is connected. The structure of an ejection mechanism is simplified, and the number of parts is reduced and assembling operability is improved. The push rod is held so as to reciprocate movably while constantly biased in an IC-card ejection direction, outside of a frame to guide insertion/removal of the IC card. A transmission pin attached to the push rod is engaged with a heart-shaped cam groove provided in an outer side surface of the frame. The transmission pin is constantly biased by a spring force of an elastic piece integrated with the push rod toward the cam groove. When the IC card is inserted, as an operation member of the transmission pin is held in the cam groove, the push rod is locked in the predetermined approach position. When the push rod, lock-released and projected, is pushed to the approach position, the transmission pin drives a driving plate entering the cam groove, to eject the IC card via an eject arm.

The structure of an ejection mechanism is simplified, and the number of parts is reduced and assembling operability is improved. The push rod is held so as to reciprocate movably outside of a frame to guide insertion/removal of the IC card.

A heart-shaped cam groove engaged with an operation member of a transmission pin is provided in the outer side surface of the frame. When the IC card is inserted, the operation member is held in the cam groove, and the push rod is locked in the predetermined approach position.

Connector device for IC card

In an IC card connector device capable of holding a push rod at a push position while an IC card is connected, a heart-shaped cam groove 10 capable of holding a push rod 4 at two positions (a push position and a projecting position) in association with a transmission pin 12 is formed on the outside surface of a frame 3 having a guide groove 3a for inserting and withdrawing an IC card 1 which is formed on the inside surface thereof and a lock lever 16 is held to a knob 4a at the extreme end of the push rod 4 to thereby lock the push rod 4 at the push position by the lock lever 16 while the IC card 1 is connected. When the IC card 1 is to be discharged, the lock of the push rod 4 is released by actuating the lock lever 16 and thereafter the knob 4a is pressed to thereby move the push rod 4 from the push position to the projecting position. Then, an eject arm 5 is turned by pressing a drive plate 15 by the transmission pin 12 in the process that the push rod 4 is moved again from the projecting position to the push position to thereby discharge the IC card 1. With this arrangement, the discharge of the IC card against the operator's intention which has connected can be prohibited and the size of an eject mechanism can be reduced.
