The modular plug 2 has a structure shown in FIGS.
As shown in FIG. 3, a housing 24 as a plug body and a claw portion 25 protruding obliquely upward are provided on the upper side thereof, and a hook 26 for preventing the return is provided on the base side of the claw portion 25. It is provided on both sides of. The claw portion 25 moves in the direction of the arrow in FIG. 7A when the tip side of the claw portion 25 and the bottom side of the housing 24 are sandwiched with fingers and a force is applied, and the claw portion 25 moves upward in the direction of the arrow of FIG. ) Approaching the 15 side, (b) in the figure
The urging state shown in Fig. 6 is set, and when the finger is released, the original position is restored again. On the upper end side of the housing 24, a protrusion 27 that protrudes from the front end surface 28 of the housing 24 is provided, and a cord insertion hole (not shown) is formed on the rear end side of the housing 24. The cord 21 is inserted into the hole, and, for example, four lead wires (not shown) drawn from the cord 21 are arranged in the housing 24.

As shown in FIG. 9, six terminal receiving grooves 29 are formed on the bottom side of the housing 24, and the plug terminals 30 are provided in the four terminal receiving grooves 29 except the terminal receiving grooves 29 on both sides. And the plug terminal 30 is electrically connected to the lead wire pulled out from the cord 21.

As shown in FIG. 11, the modular plug fitting hole 20 formed in the connector portion 23 of the modem card 1 is provided with a guide portion 4 for setting the insertion direction of the modular plug 2. The modular plug 2 can be inserted along the guide portion 4 from the inlet side 22 of the modular plug fitting hole 20 to the inner side. As shown in FIG. Protrusion 27
However, by contacting the tip position setting portion 5 of the modular plug fitting hole 20 as shown in FIG. 12 (b), the modular plug 2 is prevented from further advancing.

A return preventing portion 6 is provided on the upper side of the inlet of the modular plug fitting hole 20 to prevent the inserted modular plug 2 from coming off and locking the modular plug 2, and the modular plug 2 is fitted into the modular plug fitting hole 20. The projection 27 of the modular plug 2 into the modular plug fitting hole.
Immediately before contacting the tip position setting portion 5 of 20, the rear end side of the hooking portion 26 of the modular plug 2 is caught by the return preventing portion 6, whereby the modular plug 2 is brought into the inlet side 22 of the modular plug fitting hole 20. It does not come off from the modular plug fitting hole 20 when it returns.

When removing the modular plug 2 from the modular plug fitting hole 20, the claw portion 25 of the modular plug 2 protruding from the modular plug fitting hole 20 is removed as shown in FIG. It is pushed down with a finger or the like to come close to the upper surface 15 side of the housing 24, and the hook portion 26 is removed so as not to be caught by the return prevention portion 6.

As shown in FIGS. 11 and 12, for example, six terminal mounting grooves 18 are provided on the lower side of the modular plug fitting hole 20.
Is formed, and the tip side of the connecting terminal 8 is attached to the four terminal attaching grooves 18 excluding the terminal attaching grooves 18 on both sides, and the connecting terminal 8 is connected to the plug terminal 30 of the modular plug 2. When the modular plug 2 on the tip side of the cord 21 is inserted and fitted into the connector portion 23, the modem card 1 is connected to a communication line such as a telephone line. Become.

By the way, when the modem card 1 is inserted and mounted in a personal computer or the like, the connector portion on the rear end side of the card 1 projects from the main body of the device such as the personal computer. Since it is thick, there is a problem that it is an obstacle if the thick connector portion 23 projects from the apparatus main body. In addition, when moving a device such as a personal computer, the modular plug 2 is often removed from the connector portion 23, and the modem card 1 is often moved with the device still inserted in the device. There is a problem that the thick connector portion 23 hits a desk such as a personal computer, which may cause a trouble in the modem card 1 and the main body of the apparatus.

Further, when the modem card 1 is manufactured, if the rear end side of the modem card 1 is made thick in order to provide the connector portion 23, the material cost and the cost of the card increase accordingly. There was also a problem.

Therefore, in order to solve the above-mentioned problems, the present applicant, as shown in FIG. 5, provides a slide accommodating hole 9 on the rear end side of the card, and this slide accommodating hole 9 is almost the same as the card. A slide plate 7 having a thickness that can be freely inserted and removed in the direction of arrow A'is attached, and a rear end open opening slit 3 is provided as a modular fitting portion for detachably inserting and fitting the modular plug 2 into the slide plate 7. I proposed a communication card provided with (Japanese Patent Application No. 5-58543). In this card, as shown by an arrow A in the figure, the modular plug 2 is inserted into the opening slit 3, that is, the modular plug 2 is inserted in a direction parallel to the card surface of the modem card 1 (lateral direction in the figure). It's a card.

In this modem card 1, as shown in FIG. 6, the slide plate 7 is urged in the pulling-out direction between the slide plate 7 and the modem card 1 so that the slide plate 7 is removed from the slide accommodating hole 9. A push spring 10 that functions as a biasing means for popping out is provided, and the slide plate 7 is inserted and housed in the slide housing hole 9 against the biasing force of the push spring 10, and in this housed state. Locking means (not shown) for preventing the slide plate 7 from popping out is interposed, and the slide plate 7 is normally blocked by the lock means and is housed in the slide housing hole 9. For example, if the force that prevents the push-out spring 10 from popping out by the locking means is removed by an operating means (not shown) or the like, the slide plate 7 is pushed out by the spring 10 and pops out from the slide accommodating hole 9. It has become way.

A return prevention portion 6 and a terminal 8 are provided on the inner wall of the opening slit 3, and the modem card 1
When connecting the modular plug 2 to, connect the terminal 30 of the modular plug 2 to the modem card 1 as shown in FIG.
From the state where the terminals 8 of the modular plug 2 face each other, that is, the state where the terminal 30 of the modular plug 2 is oriented downward, the modular plug 2 is rotated 90 degrees and the upper surface of the housing 24 (the surface on which the claw portion is disposed) is rotated. Insert 15 as shown in the arrow A in the drawing with 15 facing the back and the terminal mounting surface 14 facing the front in the drawing.

Then, the modular plug 2 is inserted along the inner wall of the opening slit 3 of the modem card 1, and the tip side of the protrusion 27 of the modular plug 2 is opened by the opening slit 3.
It comes into contact with the tip position setting portion 5 of the No. 3 and does not move further, and in this state, the rear end side of the hooking portion 26 is caught by the return prevention portion 6 of the opening slit 3, whereby the modular plug 2 has the opening slit. 3 is prevented from returning to the rear end side and coming off, and the modular plug 2 is fitted in a state of protruding in the thickness direction of the modem card 1. And
By fitting the modular plug 2 into the opening slit 3, the terminal 30 of the modular plug 2 and the terminal 8 of the modem card 1 are electrically connected.

When the modular plug 2 is removed from the opening slit 3, the claw portion 25 of the modular plug 2 is brought close to the upper surface 15 side of the housing 24, and the hook portion 26 of the modular plug 2 becomes the return prevention portion 6 of the opening slit 3. The modular plug 2 can be removed by pulling out the modular plug 2 to the rear end side of the opening slit 3 in a state where it is not caught. Then, when the modular plug 2 is removed from the opening slit 3, the modular plug 2 and the terminals 30 and 8 of the modem card 1
The connection between them is released.

Modem card 1 formed in this way
In the above, when the modular plug 2 is fitted into the modular plug fitting hole 20, a part of the modular plug 2 protrudes from the slide plate 7 in the thickness direction, but unlike the modem card 1 shown in FIG. Since it does not have a thick connector portion 23 and the slide plate 7 can be accommodated in the slide accommodating hole 9, the modular plug 2 is inserted into the modem card 1
When the modem card 1 is not attached to the personal computer, the modem card 1 does not protrude from the main body of the personal computer or the like even when the modem card 1 is still attached to the personal computer.
Is not in the way. Further, since the thick connector portion 23 is not formed, the material cost is reduced and the card cost can be reduced.

[0019]

However, FIG.
In the modem card 1 shown in FIG. 6, the slide plate 7 is constantly urged in the pop-out direction by the push spring 10,
After inserting the modular plug 2 into the modem card 1 and using it, the user must store the slide plate 7 in the slide receiving hole 9 against the biasing force of the push spring 10.
It was troublesome. Therefore, the user often neglects or forgets to accommodate the slide plate 7, and then the slide plate 7 is left protruding from the slot of the personal computer or the like. In many cases, when a personal computer or the like was moved, the slide plate 7 got in the way and the modem card 1 and the main body of the device were damaged.

Further, in the modem card 1 of FIGS. 5 and 6, when the locking means fails or is damaged, the slide plate 7 is housed in the slide housing hole 9 against the biasing force of the push spring 10. And the slide plate 7 is left protruding from the slide accommodating hole 9, and then the slide plate 7 becomes an obstacle and damages the modem card 1 and the main body of the apparatus.

Further, in the above modem card 1,
When the slide plate 7 is accommodated in the slide accommodating hole 9, the push spring 10 is resisted against the biasing force of the push spring 10 in the protruding direction.
Since the push spring 10 is inevitably bent when it is compressed and stored, in order to shrink the push spring 10 along a linear trajectory, an axis is provided at the central position of the push spring 10 or the push spring 10 It is necessary to guide the push spring 10 on a straight track by providing a guide on the outer peripheral side. Therefore, there is a problem that the structure of the modem card 1 becomes complicated.

Further, generally, the time when the modular plug 2 is not used is overwhelmingly longer than the time when the modular plug 2 is fitted into the opening slit 3 and is used. Since the state in which the slide plate 7 is accommodated in the slide accommodating hole 9 without being fitted to is a state against the biasing force of the push spring 10, the state continues for a long time, so that the life of the push spring 10 is reduced. There was also a problem that was shortened.

The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is not to disturb when it is attached to a device such as a personal computer, and it is easy to accommodate a slide plate which is used by protruding from a card. Therefore, it is an object of the present invention to provide a communication card which has a simple structure and can be used for a long period of time without causing damage to the card.

[0024]

In order to achieve the above object, the present invention is constructed as follows. That is, according to the present invention, a slide accommodating hole is provided on the rear end side of a card having a communication circuit, and a slide plate which can be freely inserted and removed is attached to the slide accommodating hole, and a modular plug is detachably fitted to the slide plate. A communication card in which a modular fitting portion for performing the operation is formed, and an urging biasing means for urging and urging the slide plate in the insertion direction to insert and house the slide plate is provided between the slide plates. Is configured.

Further, when the slide plate is pulled out from the slide accommodating hole, the slide plate is provided with a slide locking projection for locking the slide plate to the card so as to be retractable. A protrusion urging means for urging the slide locking protrusion in the protruding direction is provided between the slide locking protrusion and the slide plate, while the modular plug fitted in the modular fitting portion is a plug. It has a claw portion protruding from the main body and the plug body, and when the modular plug is completely fitted to the modular fitting portion with the claw portion biased toward the plug body side, It is also a characteristic configuration of the present invention that there is provided a cooperating means for retracting the slide locking projection in conjunction with the locking operation of locking the retaining portion on the modular fitting side by the return movement. There is.

In the present invention having the above structure, the slide plate is normally inserted and housed by being attracted and biased in the insertion direction by the attracting and biasing means. Then, when the slide plate is pulled out from the slide accommodating hole, the slide plate is locked in the card in the pulled-out state by the retractable slide locking projection. Also, when the modular plug is completely fitted to the modular fitting part with the claw part of the modular plug biased toward the plug body side, the claw part moves back from the biased state and the modular fitting part side comes off. Since the slide locking protrusion is retracted by the interlocking means in conjunction with the locking operation of locking the stopper, the modular plug is pulled up to the place where it enters the insertion hole entrance of the slot etc. of the device body, and the modular plug is When the slide plate is removed from the modular fitting portion, the slide plate is not locked to the card but is attracted by the attracting biasing means and is inserted and accommodated in the slide accommodating hole.
