[Problems to be solved by the invention]

However, in the conventional IC card connector 100, the rear end of the eject lever 101 protrudes from the housing 102 in a state of waiting for the insertion of the IC card 110.
Since the appearance of the electronic device to which the electronic device is attached is impaired, and the electronic device protrudes from the housing 102, a hand or other foreign matter is likely to accidentally collide with the electronic device, causing an injury or damage to the eject lever 101.

Further, since a space for accommodating and mounting the eject pins 101 is required, a projection area on a printed wiring board on which the IC card connector 100 is mounted becomes large, which is an obstacle to high-density mounting.

Further, the electrical connection with the IC card 110 is as follows.
For example, the electrode part 111 of the ground line and the input / output terminal 104
, The contact timing of each input / output terminal 104 may be made different, for example, by bringing the electrode portion 111 of the power supply line into contact with the input / output terminal 104. In order to contact the electrode portions 111 of the IC card 110 exposed in a horizontal line at different timings, the input / output terminals 104 having different shapes must be used so that the contact positions are different, and as a result, the number of parts increases. At the same time, the housing 102 must be mounted at the specified mounting position, and the workability of assembling is poor.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and has been made without using an eject pin, so that the eject pin does not protrude from the housing and without increasing the size of the housing. An object of the present invention is to provide an IC card connector from which a card can be extracted.

It is still another object of the present invention to provide an IC card connector that can use a common input / output terminal to make different contact timings with the electrodes of the IC card exposed in a horizontal row.

[0012]

According to a first aspect of the present invention, there is provided an IC card connector having a housing in which a guide case housing chamber is formed, an IC card housing recess for inserting an IC card, and a recess in an IC cart insertion direction. A guide case loosely fitted in the guide case storage chamber so as to be able to advance and retreat along;
Urging means for urging the guide case in a direction protruding from the guide case housing chamber, and a stopper for contacting the guide case urged by the urging means to prevent the guide case from dropping out of the guide case housing chamber. An input / output terminal attached to the housing so that the notch of the guide case is inserted into contact with the electrode portion of the IC card inserted into the IC card receiving recess; A lock pin whose end is swingably supported,
Resilient means for urging the lock pin toward the other opposing surface of the housing and the guide case to fit the tip of the lock pin into a heart-shaped grooved cam recessed in the opposing surface; Each time insertion and release of the guide case into the guide case storage chamber is repeated by inserting the lock pin, the tip of the lock pin is alternately moved to the lock position and unlock position for the heart-shaped groove cam, and the lock pin When the tip is in the locked position, the guide case is a connection position where the input / output terminal contacts the electrode portion of the IC card, and when the tip of the lock pin is in the unlocked position, the guide case contacts the stopper. The guide case is stopped at each position of the guide case as a standby position.

[0013] In a state of waiting for insertion of an IC card,
The guide case is stopped at a standby position where the guide case is urged by the urging means and abuts on the stopper. At this time, the tip of the lock pin is located at the unlocked position of the heart-shaped cam groove.
When the IC card is inserted into the IC card receiving recess, the guide case is pushed into the guide case receiving chamber. The distal end of the lock pin moves from the unlocked position to the locked position when the guide case is pushed in. When the tip of the lock pin moves to the locking position, the tip of the lock pin is locked in the heart-shaped groove cam even if the guide case is released, and the input / output terminal and the electrode part of the IC card are connected to the guide case. Stop at the contact point where it touches. When the guide case is pushed again by the IC card, the tip of the lock pin returns from the locked position to the unlocked position, and the guide case is
It is urged by the return means to return from the connection position to the standby position where it comes into contact with the stopper.

Therefore, the IC card can be maintained in the connected state and pulled out only by the heart cam lock mechanism using the lock pin and the heart-shaped cam groove. Since the lock pin and the heart-shaped cam groove can be provided on opposing surfaces, the size of the housing does not increase, and the eject button does not protrude.

In the IC card connector according to the present invention, the housing in which the guide case housing chamber is formed and the IC card housing recess for inserting the IC card are recessed, so that the IC card connector can move forward and backward along the IC card insertion direction. The guide case loosely fitted in the guide case storage chamber and the guide case
An urging means for urging in a direction protruding from the guide case accommodating chamber, and an electrode portion of the IC card inserted into the IC card accommodating recess are attached to the housing so as to be in contact with the cutout portion of the guide case through the notch. The input / output terminal, a lock pin whose base end is swingably supported on one of the guide case and the housing, and urges the lock pin toward the other opposing surface of the housing and the guide case. Resilient means for fitting the tip of the lock pin into a heart-shaped grooved cam recessed on the opposing surface, and locks each time the push-in and push-out of the guide case into the guide case storage chamber by inserting the IC card is repeated. The tip of the pin is alternately moved to two different first locking positions and the second locking position in the heart-shaped groove cam, and the tip of the lock pin is moved to the first locking position.
When the lock case is in the locked position, the guide case is a connection position where the input / output terminal contacts the electrode portion of the IC card, and when the tip of the lock pin is in the second lock position, the guide case projects from the connection position. The guide case is stopped at each position of the guide case as the standby position moved to the position.

In a state of waiting for insertion of an IC card,
Since the tip of the lock pin is located at the second locking position of the heart-shaped cam groove and locked in the heart-shaped cam groove, the guide case urged by the urging means is stopped at the standby position. When the IC card is inserted into the IC card storage recess,
The guide case is pushed into the guide case storage chamber.
The tip of the lock pin moves from the second locking position to the first locking position when the guide case is pushed in. When the leading end of the lock pin moves to the first locking position, the leading end of the lock pin is locked in the heart-shaped groove cam at the first locking position even if the pushing of the guide case is released. It stops at the connection position where the input / output terminal and the electrode portion of the IC card are in contact. When the guide case is pushed again by the IC card, the tip of the lock pin is moved from the first locking position to the second locking position.
The guide case returns to the locking position, and the guide case is urged by the return means to return from the connection position to the standby position where the guide case contacts the stopper.

Therefore, the IC card is maintained in the connected state only by the lock mechanism using the lock pin and the heart-shaped cam groove.
Also, it can be extracted. Since the lock pin and the heart-shaped cam groove can be provided on opposing surfaces, the size of the housing does not increase, and the eject button does not protrude.

In the IC card connector according to a third aspect of the present invention, the input / output terminal has an elongated conductive portion having a support portion at one end fixed to the housing and a contact portion at the other end provided with elasticity so as to rise in the direction of the guide case. When the guide case is at the standby position, the contact portion that comes into contact with the outer surface of the guide case is moved to the connection position of the guide case, so that the notch is inserted through the notch into the IC card housing recess. It is characterized in that it is made to protrude.

The contact portion of the input / output terminal comes into contact with the outer surface of the guide case when the guide case is at the standby position, and protrudes into the IC card accommodating recess only when the guide case is moved to the connection position. Contact.

Therefore, in a state of waiting for the insertion of the IC card, the contact portion is covered with the guide case and is not exposed to the outside. No damage or damage. Since the contact portion is protected using the guide case according to the first or second aspect of the present invention, it is not necessary to newly provide another component or another mechanism.

According to a fourth aspect of the present invention, a notch is formed in a corresponding portion of the guide case for each of one or more input / output terminals, and the notch is provided at at least two or more different positions in the insertion direction of the IC card. A notch is provided.

Due to the difference in the formation position of the notch, even the same input / output terminal projects into the IC card accommodating recess at different timings as the guide case moves.

Therefore, by forming the cutout portions at different positions, even the input / output terminals formed in the same shape can be brought into contact with the respective electrode portions of the IC card in a predetermined sequence. Since the input / output terminals having the common shape are used, the types of the component parts do not increase, and the terminals can be mounted without being restricted by the mounting position of each terminal. Further, since this sequence contact is performed using the guide case according to the first or second aspect of the present invention, it is not necessary to newly provide another component or another mechanism.
