[0002]

2. Description of the Related Art A card connector used for electrically connecting a card-side electrode to a device-side electrode for signal transmission / reception or the like has a function (a function for holding a card at a predetermined set position). A card holding function) and a function of ejecting a card by retracting the card from a set position (ejection function) are known (Japanese Utility Model Laid-Open No. 5-75974). In this type of conventional card connector, separate components are used for a card holding function and an eject function (first conventional example).

On the other hand, among card connectors having a card holding function, there have been ones in which the card holding function is exerted by the elastic contact pressure of the connector-side contact member on the card, and those in which the card holding function is exerted by a lock mechanism.

As means for providing an eject function to a card connector of the type in which the card holding function is exerted by the above-mentioned elastic contact pressure, a mechanical means in which a longitudinal middle portion of a lever is swingably supported is employed. There is something.
In this device, by swinging a swing lever in one direction, a pressing portion provided on the swing lever pushes a card from the set position to the rear thereof (second conventional example). Further, as means for providing an eject function to a card connector of the type in which the card holding function is exerted by the lock mechanism, the card is pushed out from the set position to the rear from the set position by using the elastic biasing force of the spring after the lock is released. (Third conventional example).

[0005]

However, the first conventional example has a problem that the number of parts is increased, the number of assembling steps is increased, and the manufacturing cost is increased.

In the second conventional example, the length between the set position and the take-out position (discharge stroke) is defined as the length of the lever swing stroke required to retract the card from the set position to the take-out position behind it. ), The length is necessary, which impairs the operability when ejecting,
There has been a problem that it becomes a factor that hinders miniaturization of the card connector. Further, when the size of the card connector is reduced, there is a problem that the swing stroke of the lever is shortened and the ejection stroke of the card is also shortened.

In the third conventional example, there is a case where the card pushed out rearward by the elastic urging force of the spring is too strong and the card jumps out of the card connector.

The present invention has been made in view of the above circumstances and problems, and has as its object to provide a card connector that can perform a card holding function and an eject function with a single component.

It is another object of the present invention to provide a card connector which is easy to promote miniaturization and has a large card ejection stroke despite having a card holding function. I do.

A further object of the present invention is to provide a card connector in which a card pushed rearward at the time of ejecting is not likely to jump out of the card connector.

[0011]

In the card connector according to the present invention, a card holding slider 4 which is pushed by a card 100 and is moved from a retracted position to an advanced position is attached to the body 1 so as to be movable back and forth. There is provided a contact member 16 which exerts a card holding force by elastically contacting the card 100 which has pushed the slider 4 to the forward position, and the slider 4 is elastically urged in the retreating direction. In this card connector, even if the body is formed as a dedicated component of the connector, the member is also used as another component,
For example, it may be formed by a chassis of the device.

In the present invention, a locked portion 54 is provided on the outer edge of the slider 4, and a locking portion 61 as a counterpart of the locked portion 54 holds the slider 4 so as to be able to move back and forth. The swinging body 6 is attached to the body 1 so as to be swingable in the forward and reverse directions. And
When the slider 4 enters the forward movement position, the rocking body is constantly resiliently biased in the forward direction in which the locking portion 61 can be locked to the locked portion 54. According to this configuration, when the slider is pushed by the card and enters the forward position, the locked portion 54 on the slider 4 is locked by the locking portion 61 on the swinging body 6 and the slider 4 is moved to that position. To lock.

Further, in the present invention, the rocking body 6 is provided with a forward-moving elasticity in the reverse direction for releasing the locking portion 61 locked on the locked portion 54 from the locked portion 54.

Have been. The slider 4 is retracted to a position where the card holding force of the contact piece member 16 is released by the pressing of the pressing lever 62. In addition, the resilient urging force for urging the slider in the backward direction is set to be smaller than the card holding force.

According to this configuration, the locking portion on the rocking body is disengaged from the locked portion on the slider side only by performing the operation of rocking the rocking body against the forward biasing force. The operation and the operation of pressing the receiving portion on the slider side by the pressing lever on the swinging body side are performed in parallel. Further, while the contact piece member elastically contacts the card and exerts the card holding force, the pressing lever on the swinging member presses the receiving portion on the slider side to retreat the slider, and the card holding force is released. Later, the slider is moved backward by the elastic urging force urging the slider in the backward direction. As described above, when the retreating operation of the slider is divided into the mechanical pressing operation by the pressing lever and the retreating operation of the slider by the elastic urging force, the elastic urging force for urging the slider in the retreating direction is reduced. This makes it possible to reduce the size of the card, thereby preventing the card from being ejected when the card is ejected. In addition, since the resilient biasing force for biasing the slider in the backward direction is set to be smaller than the above-described card holding force, the card can be prevented from being ejected when the card is ejected. It is also possible to increase the discharge stroke of the gas.

In particular, according to the present invention, a locking piece for exerting a card holding function for holding a card at a predetermined set position on an oscillating body attached to the body, and a card for moving the card from the set position. Since a pressing lever for exerting an eject function for retracting and ejecting is provided, not only a card holding function and an eject function can be exerted by a single component, but also
It is easy to promote miniaturization.

In the present invention, the locked portion 54 is provided on the outer surface of the slider, and is inclined to the rear end side so as to be located more outward, and is continuous with the rear end of the guide surface 55. It is desirable to have a stepped locked surface 56 that does.

Further, according to the present invention, the projecting piece 63 provided on the rocking body 6 has a long front-rear direction for rocking the rocking body 6 in the reverse direction against the urging force in the forward direction. It is desirable that the front end of the operation lever 7 is connected and that the operation lever 7 is disposed along the side surface of the body 1.

Tentatively positions the card 100 with respect to the slider 4. This is a temporary positioning state (half lock state).

Here, the force by which the spring body 48 elastically urges the slider 4 in the retreating direction causes the locking portion 53 elastically urged by the spring plate 52 to be pushed outward by the end face 101 of the card 100. Is greater than the force required to
Therefore, during the insertion of the card 100 into the slider 4,
The situation where the slider 4 moves forward against the urging of the spring body 48 and it becomes difficult to mount the card 100 on the slider 4 does not occur.

As shown by the phantom line in FIG.
The state in which the slider is half-locked to the slider 4 is the initial state. In this initial state, as shown in FIGS. The pressing lever 62 protrudes inside the body 1 at an interval in the direction.

From the initial state, when the card 100 is pushed and the slider 4 is pushed together with the card 100 against the bias of the spring body 48 as shown by an arrow X2 in FIGS. As shown in FIG. 8, the locking portion 61 on the rocking body 6 is connected to the guide surface 55 of the locked portion 54 on the slider 4 side.
After that, when the slider 4 enters the forward position, the locking portion 61 gets over the locked portion 54 and engages with the locked surface 56 by the urging of the spring body 8 as shown in FIGS. Combine. Thus, the slider 4 is positioned at the forward position. Locked.

When the slider 4 is locked at the forward position, the contact member 16 resiliently contacts the electrode forming area 106 on the card 100 side as shown in FIG. This state is a proper setting state of the card 100.

When the card 100 is properly set, the receiving portion 49 protruding from the slider 4 approaches the pressing lever 62 on the rocking body 6 as shown in FIGS. State.

When the card 100 is to be ejected, the operating lever 7 is pushed forward as shown by the arrow F in FIGS. In this case, as shown in FIGS. 6 and 10, the projecting piece 63 on the swinging body 6 is pushed forward, so that the pushing lever 62 swings backward. Therefore, the receiving portion 49 on the slider 4 side is pushed rearward by the pressing lever 62, and the slider 4 retreats as shown by the arrow X3 in FIG. The retreat distance of the slider 4 at this time is longer than the distance until the contact member 16 separates from the electrode forming area 106 on the card 100 side or the front surface of the card body and the card holding force by the contact member 16 is released. The distance is not short. Therefore, after the receiving portion 49 is pressed by the pressing lever 62 and the slider 4 retreats to the position of FIG. 6, the slider 4 retreats as shown by an arrow X4 in FIG. Return to the initial position of 4. After the slider 4 returns to the initial position, the card 100 is pulled out by forcibly retracting the engaging portion 53 of the spring plate 52 from the locked portion 107 of the card 100 by pulling the card 100 backward. Can be.

In this embodiment, the resilient biasing force of the spring body 48 for biasing the slider 4 in the retreating direction is smaller than the card holding force of the contact piece member 16 described above. Therefore, while the contact piece member 16 resiliently contacts the electrode forming area 106 of the card 100 and exerts a card holding force, the situation where the slider 4 retreats due to the elastic urging force of the spring body 48 does not occur. On the other hand, slider 4
When the pressing lever 62 of the swinging member 6 presses the receiving portion 49 of the swinging member 6 to retract the slider 4 and the above-mentioned card holding force is released, the spring urging force of the spring body 48 causes the card holding force to be released. The slider 4 moves backward. Therefore, the card 1 at the time of card ejection is reduced by reducing the elastic biasing force of the spring body 48.
00 can be prevented from jumping out.
