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

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

A return preventing portion 6 is provided on the upper side of the entrance of the modular plug fitting hole 20 so as to prevent the inserted modular plug 2 from coming off and to lock the modular plug 2 into the modular plug fitting hole 20. And the projection 27 of the modular plug 2 fits into the modular plug fitting hole.
Immediately before coming into contact with the tip position setting portion 5 of the module 20, the rear end side of the hook portion 26 of the modular plug 2 is hooked on the return preventing portion 6, whereby the modular plug 2 is brought into the entrance side 22 of the modular plug fitting hole 20. It does not come back from the modular plug fitting hole 20.

When the modular plug 2 is to be removed from the modular plug fitting hole 20, as shown in FIG. 12C, the claw portion 25 of the modular plug 2 protruding from the modular plug fitting hole 20 is removed. It is pushed down with a finger or the like to approach the upper surface 15 side of the housing 24, and the hook portion 26 is removed from the return prevention portion 6 without being hooked.

As shown in FIGS. 11 and 12, for example, six terminal mounting grooves 18 are provided at the lower side of the modular plug fitting hole 20.
In the four terminal mounting grooves 18 except for the terminal mounting grooves 18 on both sides, the distal ends of the connection terminals 8 are mounted. The connection terminals 8 are connected to the plug terminals 30 of the modular plug 2. When the modular plug 2 on the distal end side of the cord 21 is inserted and fitted into the connector 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 into a personal computer or the like, the connector on the rear end of the card 1 projects from the main body of the personal computer or the like. Due to the thickness, there is a problem that if the thick connector portion 23 protrudes from the apparatus main body, it is an obstacle. Also, when moving an apparatus such as a personal computer, the modular plug 2 is detached from the connector section 23 and the modem card 1 is often moved while being inserted into the apparatus. There is a problem that the thick connector portion 23 may hit a desk or the like of a personal computer or the like, which may hinder the modem card 1 or the apparatus body.

Further, when the modem card 1 is manufactured, if the rear end side of the modem card 1 is made thicker in order to provide the connector portion 23, the material cost is correspondingly increased and the card cost is increased. There were also problems.

In order to solve the above problem, for example, as shown in FIG. 6A, a slide accommodation hole 9 is provided in the modem card 1 and a slide plate 7 which can be freely inserted into and removed from the slide accommodation hole 9 is provided. Attach to this slide plate 7,

Means (not shown) are interposed, and the slide plate 7 is usually held by the slide plate holding means,
The slide plate 7 is accommodated in the slide accommodating hole 9. For example, when the holding force of the slide plate holding means is removed by operating means or the like, the slide plate 7 is pushed out by the pushing means and jumps out of the slide accommodating hole 9. ing. Then, the slide plate 7 protruding from the slide accommodation hole 9 is locked by the slide plate locking means, whereby the state where the slide plate 7 is pulled out is maintained.

A return preventing portion 6 and a terminal 8 are provided on the inner wall of the opening slit 3.
When the modular plug 2 is connected 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 modular plug 2 has 2 by rotating it 90 degrees so that the upper surface 15 of the housing 24 faces
14 is turned to the front side of the figure, and inserted as shown by the arrow A in the figure.

Then, the modular plug 2 is inserted along the inner wall of the opening slit 3 of the modem card 1, and the distal end side of the projection 27 of the modular plug 2 is opened.
Abuts on the leading end position setting portion 5 and does not advance any further. In this state, the rear end side of the hooking portion 26 is hooked on the return preventing portion 6 of the opening slit 3, whereby the modular plug 2 is opened. 3 is prevented from coming back to the rear end side, and the modular plug 2 is fitted with the modem plug 1 protruding in the thickness direction. 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.

To remove the modular plug 2 from the opening slit 3, the claw 25 of the modular plug 2 is pushed down to the upper surface 15 of the housing 24, and the modular plug 2 is removed.
The modular plug 2 can be removed by pulling the modular plug 2 to the rear end side of the opening slit 3 in a state where the hooking portion 26 is not hooked on the return prevention portion 6 of the opening slit 3.
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 are removed.
The connection between them is released.

When the modem card 1 is turned over and inserted into a personal computer or the like, the slide accommodating hole 9 and the slide plate 7 are positioned on the near side in the figure, and the opening slit 3 is also turned over so that the return preventing portion 6 is positioned on the near side. In order to be able to do so, the modular plug 2
