Abstract

PURPOSE:To accurately prevent an IC card from being ejected by a simple structure and an operation by forming a rugged face on the side of the IC card and fitting a locking mechanism consisting of a curved cam groove and a pin control means to the side of a connector. CONSTITUTION:When the IC card starts to be inserted, a slider 6 is moved to the depth of a connector body, a locking cam 10 is pushed up, a spring for the locking cam 10 is contracted, and a pin 14 is positioned on the point (a) of the cam groove 16. A connector terminal is moved down and allowed into contact with the card terminal of the IC card 18, so that communication can be attained. Since the (i) position of a cam guide is formed like an L-shape, a fixed state can be obtained. When the IC card 18 is inserted into a deeper position with force, the cam 10 passes the right side of the groove 16 by the curve of the guide 22 and held at a point (e). Since the cam 4 is positioned on the upper part from the points (g), (h), (i) of the cam guide, the IC 18 card can be easily ejected.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a connector into which an IC' card is inserted, and particularly relates to a locking mechanism part. <Prior Art> A card into which an IC (integrated circuit) is inserted. The type information storage medium is
Due to its compactness and large memory capacity, it has been attracting a lot of attention as an information storage medium to replace the floppy disk. Among them, memory cards without CPUY are widely used as game memory in fj because they are easy and inexpensive.

A connector is used to freely insert and remove such an IC card from the main body of the device, but in order to prevent damage to the IC due to incorrect removal during memory access, it is necessary to avoid unnecessary removal during memory access. Some devices have appeared that have a locking mechanism that prevents this from happening.

In other words, as shown in FIG.
ce ), the reaction force at the time of insertion is 0,
After the card is completely inserted, the card is fixed by the spring force of the spring terminal, and since the card's spring-pressed foot is concave, it is locked between it and the convex spring terminal. Next door.

It was designed so that it could not be pulled out easily.

<Problems to be solved by the invention> However, such a ZIF type locking mechanism can be pulled out if a strong force is applied to try to pull it out, in which case the terminals of the connector will curl up and become unusable again. There were cases where it was put away.

The present invention was made in view of the above-mentioned current situation of tapping, and the present invention is made by forming an uneven part on the side surface of an IC card, and when inserting such an IC card. A lock cam vertically moving means consisting of a lock cam, a bottle, and a spring for moving left and right according to the uneven state of the side surface, and a bottle control that is provided with a desired curved cam St so that the movement of the bottle is controlled by the cam groove. A locking mechanism consisting of means? The present invention provides an IC card connector which is provided on the side of the connector so that accidental removal of the IC card can be accurately prevented by a 2% simple mechanism and simple operation.

<Embodiments> The present invention will be described below based on embodiments with reference to the drawings. As shown in FIG. IC card terminal (4), IC card guide slider +6), slider spring (8), lock cam which is part of the locking mechanism.
It consists of 101 etc.

The IC card reader inserted into such a connector is provided with a card terminal (sword), and a lock guide for operating the locking mechanism has a predetermined unevenness on a part of the side surface.

Furthermore, as shown in FIGS. 6 and 4, one end of the slider spring +81 is attached to the connector body (2).
Another end is connected to the slider 6), and the IC card (slider 6) is connected to the IC card (slider 6 depending on the insertion state for 1 second).
The upper right corner of the Unao slider 6) that moves from side to side as shown in Figure 44 is the movement of the lock cam 10)? Canted shape for control.

The terminal on the left side of the connector terminal 14) is formed into a plug for direct connection to the main unit, and the other terminal extends into the connector main body, and its tip is bent and has an elastic shape. When the IC card (1 &
The lock cam guide 1221 provided in a part of the IC card (1 & The depth of the dovetail formed with the concavo-convex portion shown in the figure is in the relationship i>g'>h>j, and is an important part of the lock cam mechanism.

Furthermore, the lock cam mechanism is disposed in a part of the space on one side of the connector main body (2), and as shown in FIG.
11 It is opened from the cam 4061. Is the lock cam spring 15 band-shaped and V-shaped? Its both ends are fixed, and a recess is formed in the center part to receive the bottle/circle, and the pressing force from the lock cam 10) causes the center part of the spring for the lock cam, which is made of an elastic body, to is now moving toward the back. Bar-shaped bottle (141
is connected to the lock cam] (1) so that it can be freely transmitted from left to right, and the tip of the bottle fits in the cam groove t161, and when the lock cam moves up and down, the bottle moves in the groove of the cam groove t16). It has four erections that follow the curved shape. As shown in Figure B, the cam groove has a curved shape according to a certain rule, and the groove interval is
．． It is about the extent that il is inserted.

Function> Next, the function of the lock cam mechanism when an IC card is actually inserted into the connector of the present invention will be explained based on FIG.

First, when an IC card is not inserted at all, the lock cam is completely pushed up by the side surface of the slider (6), and the lock cam spring +12) is in a retracted state, as shown in FIG. At this time, the bottle (1 hole is the cam groove aω
It is held at position a.

Then, when you start inserting the IC card, the slider 6) moves toward English as shown in Figure B.

Along the concave shape curve ρ on the side of the sputum slider.

The lock cam slides down due to the reaction force of the lock cam spring, and at this time the pin passes through the left side of the cam groove.
The bottle moves from the top of the IC card to position b. Next, the lock cam is pushed up by the g curve and tap root of the lock cam guide on the vR side of the IC card, and the bottle returns from position b to position d and back.

Next, a description will be given of the case where the IC card is inserted and the hearing aid is completely fixed to the connector, based on CK in the same figure. In other words, is the IC card further removed from the state shown in Figure B? When inserted, the lock cam fits into the notch at position i of the lock cam guide, and the pin α41 passes through the left side of the cam groove again and moves to the C tunnel, where it stops, as shown in Figure 2. Like, the elasticity pushed up by the thickness of the slider 6)? Connector with one terminal (4)
teeth.

When the IC card is inserted, it moves downward due to its elastic force and comes into contact with the card terminal/end of the IC card.

It becomes possible to communicate. Furthermore, in this state, since the slider spring 18) connected to the slider 6) is sufficiently compressed, a reaction force of the spring in the pulling direction is applied, and the shape of the lock cam guide at the i position is is L
Because of the shape of the letters, even if you try to forcefully pull the IC card out, it won't pull out, and there will be no wobbling from side to side, making it look like it's locked in place.

If you want to pull out the IC card from a locked state such as when data communication has ended, apply even more force to the IC card and insert it deeper than the fixed point. At this time, as shown in Figure 46, the lock cam Irj is pushed up by the curved card from the i position to the 3rd position and 1st position of the lock guide, and at this time, the lock cam Irj is pushed up.
I41 passes through the right side of the cam groove aQ in the drawing and is held by a bolt until it reaches the point eAO. Pin' at this point e! When the lock cam (4) is stuck in the ground, the lock cam (4) is pushed up by g, h, i, and d of the lock cam guide, so the tensile force I is applied to pull it out.
If it is added to an IC card, it can be easily removed. Then, the slider 161 is returned to its original use by the reaction force of the slider spring 8, and the lock cam is pushed up by one surface of the slider, and the pin is returned to the initial position at point a of the cam groove. The 51st cycle of return is completed.

As another example, as shown in Figure 7, the micro switch 1.3o+'v may be connected to the pin 141 of the cam ω (141) with the micro switch arm 1.3zwo.
In other words, when the card terminal of the IC card and the connector terminal of the connector are in contact and locked, the pin 141 is positioned at point C at the tip of the cam groove ub+, so at this time the micro Micro switch arm G? Contact terminal A made to look like #@ with J
comes down and comes into contact with the contact terminal B, which is fixed in advance in the orientation compensation, and at this time the microswitch is in an ONO state. By connecting between the Vcc terminal of the connector of the microswitch and the Vcc power supply and keeping it at ℃, even if you accidentally try to remove the card 2 during data communication between the IC card and the main unit,
415: J-wise, contact terminal A of the microswitch is pin 1
4), the switch is turned OFF, stopping the power source supply, and preventing the memory in the card from being destroyed.

Further, the CPU control signal may be connected to the nuclear microswitch, and the CPUK may be imprinted during the card removal operation.The locking mechanism may not only be provided at one location of the connector, but may also be provided at several locations.

<Operation> The present invention is as described above, and even if an IC card is forcibly removed in the locked state, it will be impossible because the lock cam is completely engaged with the four parts of the lock cam guide, and it will be impossible for children such as children to remove the IC card. The IC card is more accurately prevented from being destroyed due to mischief or inadvertent removal, and since there is no need to worry about operating the release lever to release the lock, the locking mechanism has an SN type structure, and furthermore, the IC card can be inserted and removed easily. The operation is simple as it only needs to be inserted and inserted.
More microswitches? By arranging the lock so that it moves, it is possible to prevent the IC card from being destroyed due to the IC card being pulled out due to accidental unlocking.
