In addition, the cover member 8 is formed to cover the upper surfaces of the plurality of connector terminals 2 arranged in the housing portion 1a of the housing 1, and prevents intrusion of radiation noise from the outside. It also serves as a shield plate.

The card 9 has an integrated circuit (IC) housed therein and is widely used as a recording medium. On one surface of the card 9, a plurality of contact terminal portions (not shown) are formed at one end thereof, and the contact terminals are arranged in the housing portion 1a of the housing 1. By contacting with the terminal 2, various information processing with the electronic device connected to the exterior is performed.

When the card 9 is inserted into the slide member 6, the front edge is engaged with the card receiving portion 6b of the slide member 6 so that the slide member 6 causes the card 9 to be inserted. Is formed to be movable in the insertion direction with the insertion of

Moreover, the one side surface part of the said card 9 is provided with the recessed recessed part 9a. The locking projections 6c formed on the base 6a of the slide member 6 are engaged with the locking recesses 9a so that the card 9, like the slide member 6, It is held at the insertion position of.

Next, an operation in the case where the card 9 is inserted into the connector device will be described using Figs. 10 to 15. The figure is shown in the state except the upper plate part 7a of the said guide plate 7 in order to make operation easy to see.

First, the card 9 is inserted in the card insertion portion 1b of the housing 1. At this time, the side front part of the said card 9 abuts against the engagement protrusion part 6c of the said slide member 6, and the said slide member 6 is the 1st spring piece 7h of the said guide member 7; The engagement projections 6c are rotated in a direction in which the engaging projection 6c is pulled out of the card insertion mounting portion, i.e., counterclockwise, with the support shaft 6d as a point (FIG. 10).

From this state, when the card 9 is inserted inward, the card 9 is engaged with the engaging recess 9a by the engaging projection 6c, and the card 9 is engaged with the slide member 6. Will be maintained. At this time, the slide member 6 is applied with a force in the discharge direction of the card by the elastic force of the return spring 3. In this case, the contact terminal portion (not shown) of the card 9 is separated from the connector terminal 2 of the housing 1 (FIG. 11).

Next, when the card 9 is pressed further in the insertion direction of the card, the slide member 6 is engaged with the front edge of the card 9 or the card receiving portion 6b of the slide member 6. Is movable in the insertion direction with the insertion of the card 9, and the slide member 6 is moved in the insertion direction of the card in response to the elastic force of the return spring 3.

And with the movement of the said slide member 6, the one end of the said lock pin 4 elastically supported by the 2nd spring piece 7i of the said guide member 7 of the heart-shaped cam groove 1g is carried out. The cam groove 1h is moved inward, i.e., in the insertion direction of the card. At this time, one end of the lock pin 4 presses the arm 7c of the guide member 7 so that the guide member 7 resists the elastic force of the elastic spring 5 to insert the card. Direction of movement (FIG. 12).

Then, by releasing the pressure in the insertion direction of the card, one end of the lock pin 4 follows the cam groove 1h of the heart-shaped cam groove 1g, and the lock recess is formed along the cam groove 1h. It is locked at the lock position, i.e., the inserting and mounting position of the card by being caught by 1i. In this case, the lock pin 4 is pressed into the locking recess 1i by the locking protrusion 7d of the guide member 7 elastically supported by the elastic spring 5, In addition, movement in the return direction in the heart-shaped cam groove 1g is restricted.

At this time, the locking recess 9a is formed in one side surface portion of the card 9, and the locking recess 9a is formed on the base 6a of the slide member 6a. By engaging the engaging projection 6c, the card 9 together with the slide member 6 is held at the insertion position of the card. Further, the contact terminal portion (not shown) of the card 9 and the connector terminal 2 arranged in the housing 1 come into contact with each other (Fig. 13).

In this way, the locking pin 4 is urged to the locking recess 1i in the locked position by the locking protrusion 7d of the guide member 7 elastically supported by the elastic spring 5. Since it is possible to prevent rattling of the lock pin 4 in the locked state, the insertion and mounting state of the card 9 can be stabilized.

In addition, since the movement of the lock pin 4 in the return direction in the heart-shaped cam groove 1g is restricted by the locking projection 7d, the lock pin 4 is provided in the heart-shaped cam groove 1g. 4) Since there is no need to form a step for restricting the return from the locking recess 1i, the thickness of the heart-shaped cam groove 1g portion can be made thin, so that the housing 1 can be thinned. Can be.

Next, in the case of discharging the card 9, from the state of FIG. 13, if the card 9 is further pushed inward, that is, in the inserting direction of the card, the slide member 6 moves inward and the One end of the lock pin 4 is moved along the cam groove 1h of the heart-shaped cam groove 1g in a direction deviating from the lock recess 1i.

At this time, the lock pin 4 is pressed to the lock recess 1i by the locking protrusion 7d of the guide member 7 elastically supported by the elastic spring 5, Since the movement in the return direction in the heart-shaped cam groove 1g is restricted, one end of the lock pin 4 is in the upper left direction shown along the second inclined surface 7f of the locking projection 7d. It moves (FIG. 14).

And when the pressurization to the said card 9 is released from this state, the said lock pin 4 will return in the said heart-shaped cam groove 1g by the 2nd inclined surface 7f of the said locking protrusion 7d. Since the movement to the front side is restricted, the slide member 6 is moved along the discharging direction of the card along the cam groove portion 1h on the left side of the heart cam groove 1g. The elastic force returns to the initial position, which is the discharge position of the card (Fig. 15).

In this manner, between the slide member 6 and the housing 1, the slide member 6 is locked to the insertion position of the card, and the slide member 6 is once inward from the locked position. The lock is slid along the heart cam groove 19 for releasing the locked state and discharging the card 9 by the slide member 6, and the heart cam groove 1g. Since the locking means made of the pins 4 is formed, the card 9 can be locked to the insertion position of the card with a simple structure, and the card 9 can be smoothly moved to the discharge position of the card. It is possible to discharge.

Next, using FIG. 16, the operation | movement in the case where the impact from the exterior is applied in the state which the said card 9 was inserted in the said housing 1 is demonstrated.

As shown in Fig. 13, in the state where the card 9 is inserted into the housing 1, the slide member 6 has one end of the lock pin 4 for locking the heart-shaped cam groove 1g. It is engaged with the recessed part 1i, and is hold | maintained in the insertion position of a card.

When an external shock is applied in this state, gravity acts on the card 9 and the slide member 6 by the impact force, and the card 9 and the slide member 6 return to the card by the action of the applied load. Resistant to the elastic force of the spring 3, it is moved instantaneously, i.e., in the insertion direction of the card. At this time, one end of the locking pin 4 engaged with the locking recess 1i of the heart-shaped cam groove 1g is formed along the second inclined surface 7f of the locking projection 7d. Along with (1h), it is going to move in the direction which leaves | releases from the said recessed part 1i for locks.

At this time, the housing 1 is provided with the guide member 7 arranged to be movable in the insertion direction of the card like the slide member 6, and the guide member 7 is provided with the heart-shaped cam groove. The locking protrusion 7d is formed to face the locking recess 1i of (1g). Then, the guide member 7 discharges the card to the elastic spring 5 having an elastic force smaller than the elastic force of the return spring 3 which elastically supports the slide member 6 in the ejecting direction of the card. Force is applied in the direction.

Therefore, gravity acts on the card 9 and the slide member 6 by an impact force from the outside, and the card 9 and the slide member 6 are moved by the action of the applied load. At the same time as it moves inwardly, i.e., in the direction of insertion of the card, against the elastic force, gravity also acts on the guide member 7, and the guide member 7 also acts as a force of the applied load. It resists the elastic force and moves instantaneously, i.e., in the insertion direction of the card.

At this time, the elastic force of the elastic spring 5 elastically supporting the guide member 7 with respect to the elastic force of the return spring 3 elastically supporting the card 9 and the slide member 6. Since the side is made small, the guide member 7 moves momentarily faster than the card 9 and the slide member 6 move momentarily. Then, the locking projection 7d is separated from the locking recess 1i by the movement of the guide member 7 so that the locking pin 4 is driven by the second inclined surface 7f. Since it is not regulated, the lock pin 4 moves along the cam groove 1h along the cam groove 1h in the direction of being released from the lock recess 1i along the second inclined surface 7f formed on the lock protrusion 7d. To prevent them from doing so.

At this time, one end of the locking pin 4 is in contact with the guide protrusion 1j formed to face the upper side of the locking recess 1i, thereby showing the right direction (clockwise), that is, the lock protrusion. It is formed to rotate to the said 1st inclined surface 7e side of 7d, and the said lock pin 4 rotates in the direction which comes out from the said recessed part 1i, ie to the left direction (counterclockwise direction) shown. It is supposed to prevent you from exercising.

In this manner, the locking recess 1i is formed in the heart-shaped cam groove 1g as the locking portion, and the locking pin 4 is opposed to the locking recess 1i in the guide member 7. The locking projection 7d for guiding the reference), and when the impact is applied, the locking projection 7d is detached from the locking recess 1i, so that the locking pin 4 The silver moves in a direction away from the lock recess 1i like the lock protrusion 7d, so that movement in the direction away from the lock recess 1i along the cam groove 1h becomes impossible. Therefore, with a simple configuration, it is possible to prevent the card from being thrown out by the impact.

In addition, since the lock pin 4 is not a (pressing) configuration that is regulated by a regulating member or the like so as not to be detached from the lock portion, deformation or breakage of the lock pin 4 or the like can be prevented.

Further, in the heart-shaped cam groove 1g, the guide protrusion 1j is formed opposite the lock recess 1i, and when the impact is applied, the movement of the guide member 7 is accompanied. Since the lock pin 4 is made to move toward the first inclined surface 7e along the guide protrusion 1j, the lock pin 4 can be moved to the first inclined surface even when the impact is large. Therefore, it is possible to reliably prevent the card from popping out.

In addition, since there is no impact from the outside, the guide member 7 moves in the ejecting direction of the card by the elastic force of the elastic spring 5, so that by returning to the initial insertion state of the card shown in FIG. The card 9 can be taken out by pushing the card 9 inward again.

17 shows the operation in the case where the impact from the outside is more strongly applied. In this case, stronger force is applied to the card 9 and the slide member 6 and the guide member 7 by the impact force, so that the card 9 and the slide member 6 and the guide member. (7) is instantaneously moved further inward, i.e., the inserting direction of the card, against the elastic forces of the return spring (3) and elastic spring (5).

At this time, one end of the lock pin 4 is further rotated in a right direction (clockwise) shown along the guide protrusion 1j, that is, toward the first inclined surface 7e side of the lock protrusion 7d. do. In this way, when the impact is applied, the lock pin 4 is rotated and escaped without being regulated. Therefore, an unexpected load is applied to the lock pin 4 or the heart-shaped cam groove 1g. Since it is not applied, there is no fear of causing deformation or damage of the lock pin 4 or the heart-shaped cam groove 1g.

According to the configuration of the above embodiment, the slide member 6 arranged to engage with the card 9 and move in the insertion and discharge direction of the card in accordance with the insertion and ejection of the card is locked at the insertion and mounting position of the card. To the housing (1) having the heart-shaped cam groove (1g) and the lock pin (4), which is movable in the insertion and discharge direction of the card, and cooperates with the heart-shaped cam groove (1g) to the lock pin (4). A guide member (7) for guiding the movement of the head) and an elastic spring (5) for elastically supporting the guide member (7) in the lockable direction of the lock pin (4), thereby providing an impact from the outside. In this case, the lock pin 4 moves the guide member 7 by moving in the direction away from the heart-shaped cam groove 1g in response to the elastic force of the elastic spring 5. 7) Guided to the heart shape The card 9 is connected to the connector even when a device equipped with a card connector device is subjected to an external impact due to dropping or the like, since it is prevented from being separated from the locking recess 1i of the groove 1g. It can be prevented from popping out of the device.

As described above, the connector device for a card of the present invention includes a housing in which a card is inserted and mounted, a slide member disposed to mate with the card according to the insertion and ejection of the card so as to be movable in the insertion and discharge direction of the card. A return spring for elastically supporting the slide member in the ejecting direction of the card, and locking means for locking the slide member to the insertion position of the card against the elastic force of the return spring, wherein the lock means includes a card for the slide member. And a lock pin for releasing the lock by moving the slide member inward from the lock position, and a heart-shaped cam groove having a lock portion and in which the lock pin slides. A guide member movable in the discharge direction and cooperating with the heart-shaped cam groove to guide the movement of the lock pin; The lock pin forms an elastic spring for elastically supporting the guide member in a lockable direction, and when an impact from the outside is applied, the guide member moves away from the heart-shaped cam groove in response to the elastic force of the elastic spring. Since the lock pin is guided to the guide member to prevent the lock pin from deviating from the lock portion, the card is removed from the connector device even when an external shock is applied to the device equipped with the card connector device due to a drop or the like. It can prevent it from popping out.

The heart-shaped cam groove is provided with a lock recess as a lock portion, while the guide member is provided with a lock protrusion for guiding the lock pin opposite to the lock recess, and when the impact is applied, the lock protrusion is locked. Since the locking pin is moved in a direction away from the lock recess like the lock protrusion, the lock pin cannot move along the cam groove in the direction away from the lock recess. With this configuration, it is possible to prevent the card from being thrown out by the impact.

In addition, the lock pin is pushed into the lock recess by the locking protrusion of the guide member elastically supported by the spring for elasticity at the lock position held in the heart-shaped cam groove, so that the lock pin in the locked state is noisy. Since the jam can be prevented, the insertion and mounting state of the card can be stabilized.

In addition, since the locking pin is restricted in the return direction in the heart-shaped cam groove by the locking protrusion, it is not necessary to form a step in the heart-shaped cam groove which restricts the return of the lock pin from the locking recess. Since the thickness of the heart-shaped cam groove part can be made thin, the housing can be made thin.

Further, the locking protrusions are provided with a first inclined surface inclined in the direction in which the lock pin locks in accordance with the moving direction of the lock pin, and a second inclined surface inclined in a direction in which the lock pin is unlocked, on the contrary. In the cam cam groove, the guide protrusion is formed to face the lock recess, and when the impact is applied, the lock pin is formed to move toward the first inclined surface side along the guide protrusion in response to the movement of the guide member. Since the lock pin can be moved to the first inclined surface side, it is possible to reliably prevent the card from popping out.

In addition, since the guide member is formed of a metal material and the spring piece for elastically supporting the lock pin to the bottom side of the heart-shaped cam groove is formed integrally with the guide member, the configuration can be simplified and the number of parts can be reduced. have.
