[Means for Solving the Problems]

In the card connector of the first invention, a slider is constantly urged in the forward direction by a spring force, and the slider is pushed into the retracted position by the card against the spring force when the card is inserted. A card connector provided with a lock mechanism for positioning the slider at that position when the slider is pushed in, comprising a lateral groove extending in the front-rear direction provided on a side wall of the body and a vertical groove intersecting the lateral groove at a right angle. A locking mechanism is formed by engaging a spring-like locking piece held by the slider with the guide groove in a state of being biased in the direction of fitting into the vertical groove, and the intermediate portion swings against the side wall of the body. One end of a swing lever that is movably supported is connected to the locking piece, and a card stopper is provided at the other end so that the locking piece fits into the vertical groove. The locking lever is swung forward so that the card stopper faces the card slot of the body, while the rocking lever is swung backwards to release the card stopper from the card slot. On the other hand, a switch switching knob is attached to the side wall of the body so as to be displaceable in two positions, and when this switching knob is set to one switching position, this knob prevents reverse swing of the swing lever. The reverse swing of the swing lever is allowed only when the knob is set to the other switching position.

In the card connector of the second invention, a slider is constantly urged in the forward direction by a spring force, and a slider is pushed into the retracted position by the card against the spring force when the card is inserted. A card connector provided with a lock mechanism for positioning the slider at that position when the slider is pushed in, comprising a lateral groove extending in the front-rear direction provided on a side wall of the body and a vertical groove intersecting the lateral groove at a right angle. A locking mechanism is formed by engaging a spring-like locking piece held by the slider with the guide groove in a state of being biased in the direction of fitting into the vertical groove, and the intermediate portion swings against the side wall of the body. One end of a swing lever that is movably supported is connected to the locking piece, and a card stopper is provided at the other end so that the locking piece fits into the vertical groove. The locking lever is swung forward so that the card stopper faces the card slot of the body, while the rocking lever is swung backwards to release the card stopper from the card slot. On the other hand, a switch switching lever is attached to the body so as to be displaceable at two positions, and a push / pull lever corresponding to the other end of the swing lever is connected to the switching lever, so that the switching lever When the switch lever is set to the switching position, the push-pull lever projects to a position that prevents the swing lever from swinging backward, and when the switch lever is set to the other switch position, the push-pull lever reverses to the swing lever. It is characterized in that it is configured to retreat to a position that allows rocking.

In the card connector of the third invention, a slider is constantly urged in the forward direction by a spring force, and when the card is inserted, the slider is pushed into the retracted position by the card against the spring force. A card connector provided with a lock mechanism for positioning the slider at that position when it is pushed into, wherein the lock mechanism includes a recessed portion provided on the slider and a spring-like locking piece provided on the body. When the slider is pushed to the retracted position, the locking piece fits into the recessed portion, and the push-in lever for pushing out the locking piece fitted into the recessed portion from the recessed portion is provided on the body. Of the rocking lever, the middle part of which is supported by the body, has a protrusion at one end and a card stopper at the other end. A knob member is slidable back and forth between an engaging position that prevents the pressing lever from being pushed and a retracted position that allows the pushing lever, and the projection is engaged with a cam groove formed in the knob member. When the knob member is moved to the engagement position, the protrusion is displaced by the cam groove, the swing lever is swung forward, and the card stopper faces the card insertion / removal opening of the body, while the knob member is moved to the retracted position. It is characterized in that the protrusion is displaced by the cam groove, the swing lever swings in the reverse direction, and the card stopper escapes from the card slot.

[Action]

According to the card connector of the first invention, when the card is set by pushing the slider to the retracted position by the card,
Initially, the locking piece, which was initially engaged with the lateral groove, is fitted into the longitudinal groove when the slider reaches the retracted position, and the slider is locked at that position. Then, as the locking piece fits into the vertical groove, the swing lever swings forward, the card stopper faces the card insertion / removal opening, and the card stopper prevents the card from being forcibly removed. Also, when the switch lever is set to one of the switch positions while the swing lever is swinging forward and the card stopper is facing the card slot, this switch knob prevents reverse swing of the swing lever. Therefore, the swing lever cannot be swung backward unless the switch knob is set to the other switch position. Further, when the card is not set in the connector, the swing lever can swing forward or reverse only when the switch switching knob is set to the other switching position, and the switching knob is When the switch position is set to, the card stopper faces the card insertion / ejection slot, and the card cannot be inserted into the connector (card setting timing restriction).

According to the card connector of the second invention, forcible removal of the card is prevented by the same operation as described above. If the switch lever is set to one of the switch positions while the swing lever is swinging forward and the card stopper is facing the card slot, the push-pull lever prevents the swing lever from swinging backward. Therefore, unless the push-pull lever is set to the other switching position, the swing lever cannot be swung backward, and the card setting timing is limited.

According to the card connector of the third invention, when the knob member is slid from the retracted position to the engaged position, the swing lever is swung forward and the card stopper faces the card insertion / removal opening. Is prevented. Further, by sliding the knob member from the engaging position to the retracted position, the swing lever reversely swings, the card stopper is released from the card insertion / removal opening, and the card can be pulled out. Further, when the knob member is set to the engagement position, the push lever cannot be pushed, so that the state in which the slider is positioned at the retracted position cannot be released. When the knob member is set to the retracted position, the card stopper is released from the card insertion / removal opening, and the above state is released by pressing the push lever, and the slider returns to the forward position by the spring force, and the card is Pushed out.

As shown in FIG. 6, the cam groove 45 is inclined, and the projection 39 is displaced downward when the knob member 41 slides from the engagement position to the retracted position, and the projection 39 moves when it is slid from the retracted position to the engagement position. It is designed to be displaced upward. Further, the card stopper 40 is displaced to a position facing the card insertion slot 22 with the swing of the swing lever 37 when the protrusion 39 is displaced upward, and the swing lever 37 is swingable when the protrusion 39 is displaced downward. It is designed so that it can escape from the card slot 22 as it moves.

Other configurations, for example, three raised portions 5 are formed on the bottom surface of the body 1, and the slider 6 housed in the body 1 is movable back and forth between the forward and backward positions. , The slider 6 is constantly biased in the forward direction by the springs 7, 7, the slider 6 has three inclined surfaces 9 on the lower surface side, and these inclined surfaces 9 are on the raised portions 5. The point corresponding to each, the point that the uplifting mechanism 10 is composed of these raised portions 5 ... And the inclined surface 9 ...
The contacts 11a and 12a of the contact pieces 11 and 12 having a spring property correspond to the external terminals C ₁ and C ₂ of the card C respectively, and the configuration of the card C is the same as that described in FIGS. 1 to 4. Since they are similar, the same or corresponding parts will be denoted by the same reference numerals and detailed description thereof will be omitted.

Next, the operation will be described.

When the card C is not inserted, the slider 6 has a spring 7,
It is pushed by 7 and moved to the forward position shown by the phantom line in FIG. In addition, the locking piece 34 is, as shown in FIG.
Following the inclined edge 32a of the card stopper 40, the card stopper 40 is in a position where it is released from the card slot 22 (see FIG. 7) as indicated by the phantom line in FIG. From this state, as shown in FIG. 7, the front edge of the card C inserted through the card slot 22 is pressed against the stepped portion 8 of the slider 6, and then the card C is pushed in. , 7 is pushed into the retracted position against the spring force. In the middle of pushing the slider 6 in this way, the slider 6 is gradually raised by the action of the pushing-up mechanism 10, and in the process of raising the slider 6, the contact pieces 11, 12 are connected to the external terminals C ₁ , C ₂ of the card C. Contacts 11a and 12a of each contact respectively, and when the slider 6 subsequently rises, the contact pieces 11 and 12 are displaced upward against their own spring properties, and when the slider 6 reaches the retracted position, the contacts are contacted. The restoring forces of the contact pieces 11 and 12 cause the 11a and 12a to elastically contact the external terminals C ₁ and C ₂ with a large contact pressure. In this case, the contacts 11a and 12a exert a self-cleaning function.

Further, when the slider 6 retracts, the locking piece 34 is guided by the inclined edge 32a from the position shown in FIG. 8 and fits into the recess 33. Therefore, when the slider 6 reaches the retracted position, the slider 6 is positioned at that position by the engagement of the claw piece portion 32 and the locking piece 34 as shown in FIG. It is in a locked state.

When ejecting the card C, the knob member 41 is set to the retracted position so that the protruding portion 42 is suspended as shown in FIG.

To the outside of the recess 33. Then, the spring force of the springs 7, 7 advances the slider 6 to eject the card C.

Further, when the knob member 41 is set to the engaging position as shown in FIGS. 5 and 6, the cam groove 45 displaces the protrusion 39 upward, and accordingly the swing lever 37 swings, and the card stopper 40. Covers the rear end of card C. Therefore, in this state, even if the card C is forcibly pulled out, the card stopper 21 prevents the card C from being forcibly pulled out. At the same time, the projecting portion 42 corresponds to the hanging piece 36 and keeps the pushing lever 35 in a non-pushable state. Therefore, it is possible to prevent an unexpected situation in which the slider 6 accidentally moves forward to eject the card C when the card C is set.

In FIGS. 1 and 5, 100 is a card detection switch, which corresponds to the detection switch of FIG.

[Effect of device]

According to the card connector of the first and second inventions, the card stopper surely prevents the card from being forcibly removed when the card insertion is completed, so that the card is inadvertently pulled out without performing a special operation. The situation can be prevented in advance, and the card is automatically pushed out only by allowing the card stopper to escape from the card slot. Further, the reverse swing of the swing lever is prevented depending on the switching position of the switch, so that the swing lever is prevented from being swung reversely by mistake when the switch is switched to the switching position, so that the swing lever is prohibited. There is also an effect that it is possible to prevent the careless removal of a card or the insertion of a careless card (the effect of limiting the set timing).

According to the card connector of the third invention, the card can be inserted only when the knob member is in the retracted position, and when the knob member is in the engaging position, forcible removal of the card is prevented.
At the same time, the positioning of the slider by the lock mechanism cannot be released. Therefore, it is possible to reliably prevent the slider return operation (forward movement) by operating the knob member, and prevent the situation where the card is inadvertently pulled out without performing a special operation. it can.
