A hook 26 for preventing the return is provided on both sides of the claw 25. When the tip of the claw 25 and the bottom of the housing 24 are sandwiched by fingers and the force is applied, the claw 25 moves in the direction of the arrow in (a) of FIG. 7 and approaches the upper surface 15 side of the housing 24. The state shown in (b) of the figure is reached, 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 four lead wires (not shown) pulled out from the cord 21 in the housing 24.
Are arranged.

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 back and come out of the modular plug fitting hole 20.

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 is projected 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.

In order to solve the above problem, for example, as shown in FIG. 6A, the modem card 1 is provided with a slide accommodating hole 9, and a slide plate 7 which can be inserted into and removed from the slide accommodating hole 9 is provided. Attach it to this slide plate 7,
As shown in (a) and (b) of the same figure, a through modular plug fitting hole 20 is formed in the thickness direction of the modem card 1,
Connect the modular plug 2 from the front side of the modem card 1.
There has been proposed a communication card that is inserted obliquely into the modular plug fitting hole 20.

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.

However, when inserting the modem card 1 into a personal computer or the like, depending on the type of personal computer or the like,
The modem card 1 may be inserted into a personal computer or the like with its front side facing up, or the modem card 1 may be inserted into a personal computer with its front side facing down. 6, it is difficult to insert the modular plug 2 into the modem card 1 of FIG. 6, and even if it is possible to insert it, due to the thickness of the modular plug 2 that largely protrudes in the thickness direction of the modem card 1. However, the rear end of the modem card 1 is lifted up, which makes it impossible to stably install the personal computer body, which is a problem.

Therefore, the applicant of the present invention, as shown in FIG.
A slide accommodating hole 9 is provided on the rear end side of the card, and a slide plate 7 which can be freely inserted and removed in the direction of arrow A'is attached to the slide accommodating hole 9, and the modular plug 2 is detachably inserted into the slide plate 7.

Means (not shown) is interposed, and the slide plate 7 is normally held by the slide plate holding means,
The slide plate 7 is accommodated in the slide accommodating hole 9, but when the holding force of the slide plate retaining means is removed by, for example, an operating means, the slide plate 7 is pushed out by the pushing means and pops out from the slide accommodating hole 9. ing. Then, the slide plate 7 protruding from the slide accommodating hole 9 is locked by the slide plate locking means, so that the slide plate 7 is maintained in the pulled-out state.

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 the modular plug 2, the terminal 30 of the modular plug 2 and the terminal 8 of the modem card 1 are opposed to each other, that is, the terminal 30 mounting portion of the modular plug 2 is directed downward from the modular plug 2. Rotate 2 by 90 degrees so that the top surface 15 of the housing 24 faces the back of the drawing and the bottom surface
Insert 14 as shown in the arrow A of the figure, with 14 facing toward you.

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 projecting portion 27 of the modular plug 2 is 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.

Further, when the modular plug 2 is removed from the opening slit 3, the claw portion 25 of the modular plug 2 is pushed down to the upper surface 15 side of the housing 24, and the modular plug 2
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 the hooking portion 26 of FIG.
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.

When the modem card 1 is turned upside down and inserted into a personal computer or the like, the slide accommodating hole 9 and the slide plate 7 are positioned on the front side in the figure, and the opening slit 3 is turned upside down so that the return prevention portion 6 side is positioned on the front side. In that case, the modular plug 2
By inserting the modular plug 2 from the lateral direction of the drawing with the bottom surface 14 of the modular plug facing the back side of the drawing, detachable insertion and fitting into the opening slit 3 of the modular plug 2 is performed in the same manner as above. The connection between terminals 30 and 8 is also switchable.

Therefore, in the proposed modem card, the modular plug 2 is inserted into the modem card 1 regardless of whether the front surface side of the modem card 1 is inserted upwards or the front surface side is inserted downwards. Will be able to do it without any trouble.

[0023]

However, in the modem card 1 shown in FIG. 5, the modular plug 2 is used.
Since the inserting direction of the slide plate 7 and the inserting / removing direction of the slide plate 7 are the same direction (directions of arrows A and A ′ in the figure), when the modular plug 2 is inserted into the opening slit 3, the slide plate 7 is inserted into the slide accommodating hole. Since it is pushed back to the 9 side, it is necessary to insert the modular plug 2 while holding the position of the slide plate 7 with a finger, and there is a problem that it takes time and effort.

Further, when the modular plug 2 is inserted into the opening slit 3, it is inserted along the inner wall of the opening slit 3, but it is difficult to determine the insertion position in the vertical direction (up and down direction) in the figure, so that incorrect insertion may occur. It was dangerous and a problem.
