SOLUTION: A card-ejecting force is to be weakened by a striking point of a slider 5 coming in contact with a receptacle 75 when an operation member 7 is pushed in. A slider lock mechanism is fitted so as to block the retreat of the slider 5 when a card 100 is inserted into a setting position. It is so structured that a locking state of the slider lock mechanism is released through a push-in operation of the operation member 7.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a card connector,
In particular, the present invention relates to a card connector capable of discharging a card set at a card setting position through a pushing operation (push operation) of an operation member.

[0002]

2. Description of the Related Art JP-A-11-135192 discloses that
There is a description of a card connector capable of ejecting a card inserted at a card setting position through a pressing operation of an operation member. This publication also describes that the card is half-locked at the card setting position. That is, in the card connector described in this publication, when a card is inserted from the insertion slot of the housing, the card is housed in the housing and engages with the slider which is constantly resiliently biased in the retreating direction. The slider is pushed to the forward position corresponding to the card setting position against the above-mentioned elastic urging force. When the card is engaged with the slider, the card is always half-locked to the slider. That is, the card is temporarily fixed to the slider so that it can be pulled out.

The means for preventing the slider pushed in by the card inserted into the card setting position from retreating from the position is constituted by combining a heart-shaped cam groove and a pin fitted in the cam groove. A cam mechanism operated by a push-push operation has been adopted.

[0004]

However, according to the conventional card connector described in the above-mentioned publication, the slider for half-locking the card at the card setting position is retracted by pushing the operating member. When the card is ejected together with the slider, there is a possibility that the card may jump out to the rear of the connector due to the momentum when the slider retreats.

Further, even when the card is inserted into the card set position, the card is only half-locked with respect to the slider, so that the card inserted in the card set position cannot be forcibly pulled out. There is a risk that the card may be accidentally ejected by pulling the card.

Further, when the card connector receives an impact due to dropping or the like, depending on the degree of the impact, the pins of the cam mechanism are disengaged from predetermined engagement portions of the cam grooves, and the card is accidentally ejected. There was a fear that it would be.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and when a card is ejected from a card setting position by pushing an operation member, a slider which is always elastically urged rearward is provided. An object of the present invention is to provide a card connector capable of synchronizing a retreating operation with a retreating operation after pushing an operation member, thereby enabling a card to be ejected while reducing a card ejection force, thereby preventing a card from jumping out. And

Further, the present invention makes it impossible to forcibly remove the card when the card is inserted into the card set position, and furthermore, the card inserted into the card set position even if the card receives a shock such as dropping. It is an object of the present invention to provide a card connector that does not cause a situation in which the card connector is inadvertently discharged.

Further, according to the present invention, it is possible to prevent the card from being ejected when the card is ejected without increasing the number of parts as much as possible, and it becomes impossible to forcibly remove the card.
An object of the present invention is to provide a card connector which can be configured so that a card is not accidentally ejected due to an impact such as dropping.

[0010]

A card connector according to the present invention will be described with reference to the drawings. The use of reference numerals in the figures in this section is for the purpose of helping to understand the contents of the invention, and is not intended to limit the contents to the examples in the drawings.

The card connector according to the present invention is pushed from the standby position to the forward position corresponding to the card setting position by the card 100 inserted from the insertion opening 15 of the flat box-shaped housing 1 in the flat box-shaped housing 1. And a slider 5 which is constantly urged toward the retreating direction, and a slider lock mechanism for preventing the slider 5 which has been pushed into the forward position from retreating at the advanced position against the above-mentioned urged urging force. When,
An operating member 7 for releasing the locked state of the slider lock mechanism through a pushing operation, and an urging means for constantly urging the operating member 7 toward an initial position behind the pushed position are provided.

For this reason, when the card 100 is inserted through the insertion slot 15 of the housing 1, the slider 5 which is located at the standby position and is constantly urged in the retreating direction is opposed to the card urged by the cardboard. The card 100 is pushed forward by the button 100 to advance to the forward position, and the card 100 itself is inserted to the set position. When the card 100 is thus inserted into the set position, the slider lock mechanism locks the slider 5 at the forward position.
Therefore, the situation where the slider 5 pushed into the forward position by the card 100 retreats from the forward position does not occur.

When the operating member 7 is pushed in while the card 100 is inserted at the set position, the operating member 7 releases the locked state of the slider lock mechanism, so that the slider 5 is resiliently biased by the card 5 so that the slider 5 is released. With it, it retracts to the standby position.

In the present invention, the slider 5 has the contact portion 59.
A slider 5 that retreats from the advanced position when the operating member 7 releases the locked state of the slider lock mechanism through a pushing operation of the operating member 7.
Receiving portion 75 for receiving the contact portion 59 and synchronizing the retreat of the slider 5 with the return of the operating member 7 to the initial position.
have.

For this reason, when the locked state of the slider lock mechanism is released through the pushing operation of the operating member 7, the slider 5 which retreats from the forward position by receiving the elastic urging force.
Of the operating member 7 being pushed in
Is received by the receiving portion 75. In this case, the slider 5
The contact portion 59 is merely received by the receiving portion 75 of the operating member 7 which has been pushed in and approached to a position close to the contact portion 59, so that the contact portion 59 of the slider 5 which has been resiliently urged. Is received by the receiving portion 75 of the operation member 7, the situation where the card 100 separates from the slider 5 and jumps out to the rear of the connector does not occur. Further, since the operating member 7 is retracted after receiving the contact portion 59 of the slider 5 by the receiving portion 75, the card 100 also retreats in synchronization with the operating member 7 together with the slider 5.

In the present invention, the locking portions 25a, 35
The elastic pieces 24 and 34 provided with the elastic pieces 24 and 34 are provided on the slider 5, and when the slider 5 is pushed forward from the standby position, the elastic pieces 24 and 34 are bent and deformed against their elasticity, A locking portion 55 is provided to be locked to the locking portions 25a, 35a through the returning operation of the pieces 24, 34, and the slider lock mechanism is provided with locking portions 25a, 35a for the elastic pieces 24, 34. Can be adopted.

When this configuration is adopted, the locked portion 55 and the locking portion 25 when the slider 5 is pushed into the forward position are provided.
a, 35a, while the engagement operation with the slider lock mechanism is reliably performed and the operation stability of the slider lock mechanism is enhanced.
a and the locked portion 55 can have a relatively simple configuration. Such an action is formed by the rear end face of the projection 54 in which the locked portion 55 is attached to the slider 5 and protrudes rearward from the slider 5, and the slider 5 is attached to the projection 54 in the card insertion direction. Satisfactory performance can be obtained by adopting a configuration in which an inclined guide surface 56 is provided to deflect and deform the elastic pieces 24 and 34 against their elasticity when slid forward.

According to the present invention, it is possible to adopt a configuration in which the contact portion 59 is attached to the slider 5 and is formed by the rear end surface of the projection 54 projecting rearward from the slider. Is the contact part 5
9 and the locked portion 55 can be shared by the rear end face of the same projection 54 attached to the slider 5 and protruding rearward from the slider 5, so that the number of parts can be reduced. It is possible to form the contact portion 59 and the locked portion 55 without increasing the size of the contact portion.

In the present invention, the elastic pieces 24 and 34 are formed by inwardly raising and lowering the upper plate or the lower plate of the housing 1, and the openings 25 formed in the elastic pieces 24 and 34 are formed. ,
The locking portions 25a, 35a are formed by the rim of the 35, and the elastic pieces 24, 34 slide against the elastic pieces 24, 34 through the pushing operation of the operating member 7 so that the elastic pieces 24, 34 resist the elasticity. The opening 2 is deformed by bending.
It is possible to adopt a configuration in which there is provided a pointed action portion 74 for separating the rims of the 5, 35 from the rear end surface of the projection. According to this, the action of releasing the engagement between the locking portions 25a and 35a and the locked portion 55 by the action portion 74 can be exhibited with a simple configuration. In addition, even if the operation member 7 is accidentally pushed in due to a shock due to a drop or the like, the operating portion 74 releases the engagement between the locking portions 25a and 35a and the locked portion 55. Is unlikely to occur. Therefore, it is unlikely that the card 100 inserted at the set position is accidentally ejected due to an impact such as dropping.

In the present invention, the receiving portion 75 can be formed by a projecting piece bent on the operating member 7, whereby the receiving portion 75 can be formed without increasing the number of parts. Become.

According to the present invention, when the slider 5 is at the standby position, the card
When the slider 5 is at the forward position, the card 100 inserted at the card setting position is fully locked and the card 100 is retracted from the slider 5 when the slider 5 is at the forward position. It is desirable to have a card lock mechanism for preventing the above. According to this, the card 100 inserted at the card setting position is fully locked by the slider 5 and cannot be forcibly removed. On the other hand, when the slider 5 is located at the standby position, the card 100 is only half-locked to the slider 5, so that the card 100 can be pulled out and ejected.

The card lock mechanism is mounted so as to be able to move back and forth in a direction intersecting the sliding direction of the slider 5, and has a recess 120 provided in the card 100.
And a movable body 6 having a chevron-shaped tip surface 61 which is fitted and disengaged through the operation of moving over the card 100, and resiliently urges the movable body 6 in the projecting direction when the slider 5 is at the standby position. It has a spring body and a support portion for preventing the movable body 6 from retreating when the slider 5 is located at its forward position. In this case, it is preferable that the spring body is formed of a spring piece 26 which is cut and raised inward on the side plate portion of the housing 1, and the support portion is preferably formed by a plate surface inside the side plate portion. By adopting this configuration, it is possible to reduce the number of components of the card lock mechanism and reduce the cost.

In the present invention, it is preferable that the housing 1 is formed with a projection 27 which hits the slider 5 retreated from the forward position to the standby position and positions the slider 5 at the standby position. According to this, since it is not necessary to use a separate component as the protruding piece 27 positioned at the standby position of the slider 5, an increase in the number of components can be suppressed and the price can be reduced.

As shown in FIGS. 1 to 4, a slider 5 is accommodated on one side of the housing 1 so as to be slidable back and forth in the card insertion direction (arrow A in FIG. 2).
A spring 42, which is a coil spring interposed between the body 4 and the body 4, is always resiliently urged in the backward direction. As shown in FIG. 12, the slider 5 has a stepped engagement surface 51 which is curved so as to be closer to the center in the left-right direction of the housing 1 as it is closer to the front end side. As shown in FIGS. 1 to 4, an elongated rod 52 extending rearward is connected to the rear end of the slider 5. The rod 52 has a thickness capable of fitting into the openings 25 and 35 of the elastic pieces 24 and 34 provided in the housing 1. As shown in FIGS. 17 to 19, a narrow portion 53 having a predetermined length is provided at the rear end of the rod 52, and a wide projection 5 is provided near the end of the narrow portion 53.
There are four. The rear end surface of the projection 54 is formed as a locked portion 55 that is perpendicular to the card insertion direction A, and the front end surface of the projection 54 is formed as a guide surface 56 that is inclined to the front. . Further, FIG.
As shown in FIGS. 2 and 13, the slider 5 is provided with a rectangular hole 57 penetrating in the left-right direction, and the movable body 6 having the chevron-shaped tip surface 61 can freely move back and forth in the left-right direction.

At this time, the stepped portion 62 of the movable body 6 is locked to the stepped portion 58 of the hole 57 of the slider 5 so that the movable body 6 is positioned so as not to come out inside the housing 1 (FIG. 13). The state in which the movable body 6 is elastically urged inward of the housing 1 by the spring piece 26 in this manner is not only when the slider 5 is at the standby position but also when the slider 5 is at the standby position. Even when the spring piece 26 moves forward, it is always maintained as long as the spring piece 26 is in contact with the movable body 6 and is pressed. Therefore, the elastically biased state of the movable body 6 by the spring piece 26 is always maintained when the slider 5 is located at a position between the standby position and the intermediate position before the forward position. . When the slider 5 is located at the forward position as shown in FIG. 3, the movable body 6 is moved to the front of the spring piece 26 together with the slider 5, and the rear end 64 of the movable body 6 is Facing the plate surface of the side plate portion of the body 1, that is, the inner surface of the side plate portion 23 of the lower cover 2,
The movable body 6 is moved outward of the housing 1 by the inner surface of the side plate portion 23.
Is prevented from retreating. Therefore, in this embodiment, the inner surface of the side plate portion 23 is formed as a support portion 23a (see FIG. 3) that prevents the movable body 6 from retreating when the slider 5 is at the forward position. .

As shown in FIGS. 1 to 4, one of the side plates of the housing 1, that is, the side plate 23 of the lower cover 2 and the inner side and the outside of the rear end of the side plate 33 of the upper cover 3, are straddled. Operating member 7
Is provided, and the spring receiving portion 7 of the operating member 7 is provided.
A spring member 72 composed of a tension coil spring is interposed between the spring member 1 and the spring receiving portion 13 at the rear end of the housing 1, and the operating member 7 is constantly moved rearward in the card insertion direction A by the spring member 72. It has been energized. As shown in FIG. 15, the operating portion 7 is attached to the end 73 of the operating member 7 provided inside the housing 1.
4 are integrally formed. As shown in FIG. 16, the action portion 74 is formed in a wedge shape, in other words, a pointed shape. In the illustrated example, as shown in FIG.
4 is provided on the operating member 7, and the pair of operating portions 7
Reference numerals 4 respectively correspond to both ends in the width direction of a pair of upper and lower elastic pieces 24 and 34 having a symmetric shape provided in the housing 1. Further, as shown in FIGS. 15 and 16, a receiving portion 7 connected to the spring receiving portion 71 is provided in front of the spring receiving portion 71 of the operation member 7.
5 is composed.

Here, the above-mentioned protrusion 54 on the slider 5 side is used.
Is formed as a contact portion 59 received by the receiving portion 75. Therefore, in this embodiment, the contact portion 59 and the above-mentioned locked portion 55 are shared by the rear end surface of the same projection 54.

Next, as shown in FIG. 2 to FIG. 4, the card 100 has a curved portion 110 on one side of the front end and a recess 120 on one side. Then, when the slider 5 is at the standby position as shown in FIG. 1, the card 100 is inserted from the insertion opening 15 formed at the rear end of the housing 1 as shown by an arrow A in FIG. The curved surface 110 of the card 100 pushes the movable body 6 into the hole 57 of the slider 5 against the elasticity of the spring piece 26 and gets over the movable body 6 as shown in FIG. Engages. That is, the engagement surface 51
The curved surface 110 of the card 100 abuts only from behind. When the curved surface 110 of the card 100 engages with the engagement surface 51 of the slider 5, the angled tip surface 61 of the movable body 6 pressed by the spring piece 26 is inserted into the recess 120 of the card 100 in FIG. It fits like In this state, when the card 100 is strongly pulled rearward, the card 100 is retracted while pushing the movable body 6 against the bias of the spring piece 26, and the recessed portion 120 comes out of the chevron tip surface 61 of the movable body 6. Therefore, the card 100 can be pulled out. In this state, the card 100 is
Is in a locked state in which it is temporarily fixed so as to be able to be pulled out, that is, a half-locked state. Such a half-lock state continues from the state of FIG. 2 until the card 100 is further inserted and the slider 5 is pushed to the above-described intermediate position.

After the slider 5 has passed the intermediate position by the insertion of the card 100, the slider 5 reaches the forward position. At this time, as shown in FIG.
00 overlaps the terminal 41 at the card setting position and
And the electrodes on the card 100 side are electrically connected. The movable body 6 has a rear end 64 opposed to the support portion 23a formed by the plate surface of the side plate of the housing 1 as shown in FIG. Therefore,
At this time, even if the card 100 is strongly pulled rearward, the recessed portion 120 of the card 100 cannot get over the chevron tip surface 61 of the movable body 6.
0 is fully locked to the slider 5.

On the other hand, in the process of pushing the slider 5 from the standby position to the forward position, the rod 52 connected to the slider 5 also moves forward, so that the narrow portion 53 of the rod 52 is initially moved as shown in FIG. As the upper and lower elastic pieces 24 and 34 slidably sandwiched are bent, the projection 54 rides over the distal ends of the elastic pieces 24 and 34 as shown in FIG. 35
In addition, the locked portions 55 of the projections 54, 54 are engaged with the rear edges of the openings 25, 35 by the elastic force of the spring 42 shown in FIG. Therefore, the retreat of the slider 5 is prevented by the engagement between the locked portions 55 of the projections 54, 54 and the rims of the openings 25, 35, and the card 100 is fully moved with respect to the slider 5 as described above. Because it is locked,
The card 100 cannot be forcibly removed. When the projections 54 cross over the distal end portions of the elastic pieces 24, 34, the guide surface 56 inclined to the anterior constriction of the projections 54 is useful for smoothly performing the overcoming operation.

Here, the edges of the openings 25, 35 which engage with the locked portions 55 of the projections 54, 54 form locking portions 25a, 35a which lock the projections 54, 54. And
The locking portions 25a and 35a form a slider lock mechanism for preventing the slider 5 pushed into the advanced position from retreating against the elastic biasing force of the spring 42 at the advanced position.

Card 1 inserted in the above set position
When ejecting 00, the operating member 7 is pushed forward from the initial position as shown by the arrow B in FIG. When the operating member 7 is pushed in in this manner, the acting portion 74 which is separated from and opposed to the elastic pieces 24 and 34 at the initial position is slid with the upper and lower elastic pieces 24 and 34 as shown in FIG. Since the elastic pieces 24 and 34 are divided between the elastic pieces 24 and 34, and the elastic pieces 24 and 34 are flexibly deformed and expanded, the protrusions 54 are formed.
Escapes from the openings 25, 35 of the elastic pieces 24, 34. For this reason, the locked portions 55, 55 of the projection 54 and the elastic pieces 24,
The engagement portions 25a and 35a of 34 are disengaged, and the engagement between them is released. In this case, since the contact portion 59 of the slider 5 is only received by the receiving portion 75 of the operating member 7 which has been pushed and approached to a position close to the contact portion 59, the slider which is resiliently biased is used. Even if the contact portion 59 is received by the receiving portion 75 of the operation member 7, the situation where the card 100 separates from the slider 5 and jumps out to the rear of the connector does not occur. The operating member 7 is retracted by the urging of the spring member 72 after receiving the contact portion 59 of the slider 5 by the receiving portion 75, so that the slider 5 is synchronized with the operating member 7 together with the card 100 as shown in FIG. The card 100 is half-locked to the slider 5.
Therefore, at this time, the card 100 can be ejected by strongly pulling the card 100. In addition,
The slider 5 has a protrusion 27 as shown in FIG.
Is positioned at the standby position.

In this embodiment, the movable member 6 described above is used.
The spring body formed by a spring piece 26 that urges the movable body 6 in the projecting direction, and a support portion 23a that prevents the movable body 6 from retreating,
Is a component of a card lock mechanism for half-locking or full-locking. Further, the operation member 7, the action portion 74, and the spring member 72 are components of the engagement release mechanism.

In this embodiment, in order to enhance the stability and reliability of the operation, the elastic pieces 24 and 34 provided with the locking portions 25a and 35a and the projections 54 provided with the locked portions 55 are each paired up and down. Although provided, this point may be such that the elastic piece or the protrusion is provided only on the upper side or only on the lower side.

[0040]

According to the present invention, when a card is ejected from the card setting position by pushing the operating member, the slider which is always elastically urged rearward is moved backward by pushing the operating member. Synchronized with the later retreat operation, the card can be ejected while reducing the card ejection force, so that it is possible to reliably prevent the card from jumping out of the connector when ejecting the card. Will be possible.

Further, the card inserted at the set position is fully locked by the slider located at the advanced position, and the slider located at the advanced position is engaged by the engagement between the engaging portion and the engaged portion. Since it is impossible to retreat, a situation where the card is forcibly removed from the set position cannot occur. The operating portion of the operating member for releasing the engagement between the locking portion and the locked portion is located at a position separated from the engagement portion between the locking portion and the locked portion in the initial position. Therefore, it is unlikely that the engagement between the locking portion and the locked portion is released even by an impact such as a drop. For these reasons, the card inserted at the set position is not forcibly removed or accidentally ejected by an impact. Further, according to the present invention, it is impossible to forcibly remove the card without increasing the number of parts as much as possible, and it is possible to prevent the card from being accidentally ejected by a shock such as dropping. It is possible to provide a card connector which can be used.
