2. Description of the Related Art Conventionally, Ic cards have been widely used in personal computers, especially portable computers. As the currently used Ic card, a memory card specialized in a storage function is mainly used. Such an Ic card as a memory card is shown in FIGS.
As shown in FIG. 1, the integrated circuit element 2 and other circuit elements 3 are mounted on the printed board 1, the frame 4 is arranged on the outer peripheral side of the printed board 1, and the connector 5 is arranged on one end thereof. Then, the upper and lower flat portions of the printed board 1 on which these components are mounted are covered with a cover 6 to constitute an integrated Ic card 7 as shown in FIG. Such Ic cards 7 tend to be thinner and larger in capacity today due to the miniaturization of memory chips and the use of surface mount components.

[0003]

SUMMARY OF THE INVENTION As described above, the conventional Ic
The structure of the card is optimal because the structure of the memory card can be reduced in thickness and the shape of parts such as the frame 4 and the cover 6 can be simplified. However, the conventional configuration as described above cannot be used as it is as a configuration of an interface card that is an Ic card that requires a connector for performing input and output with the outside. As shown in FIG. 10, a large connector 9 and a large component are provided on an Ic card 7 connected to a computer 8, and a large cable connector 10 used for other information processing equipment is connected to this. This is because the type of the Ic card 7 integrated into a thin small plate cannot be taken as it is.

[0004] Therefore, as shown in FIG.
The card 7 is provided with a thin connector 7a. And
The thin drawer connector 12 provided in the I / o connector circuit section 11 containing the large component 13 and the connector 9 is connected to the connector section 7a and the I / o connector circuit section 1
It is conceivable that the cable connector 10 is connected to the connector 9 of the connector 1 for use. However, if the circuit is separated by providing such a thin connector portion 7a, there is a problem that the operation of the circuit becomes unstable due to electric noise or the like.

In view of the above, an object of the present invention is to newly provide an interface card in which a connector section, a large-sized component, and the like are integrated with an Ic card so that circuit operation is stabilized.

[0006]

In the interface card of the present invention , a connector is arranged at one end of a printed circuit board.
The other end of the printed circuit board has an input / output connector
Place the electrical components of the mold and
An integrated circuit element is placed in the center to
A printed circuit board, and the other end of the printed circuit board is
A thick portion made of a frame is provided, and the inside of the thick portion is
Place the I / O connectors and electrical components, and
Is fixed to the printed circuit board, and the upper and lower surfaces of the printed circuit board are fixed.
And the thick portion is covered with a cover .

[0007]

According to the above construction, the printed circuit board can be constituted by one sheet, so that it is possible to provide an inexpensive and stable product. Also, by simply changing the shape of the parts such as the frame and the cover, it can be manufactured with the same number of parts as the conventional Ic card (memory card), so that it can be easily manufactured, and the frame can be easily printed. Since the reinforcing effect can be provided, it is possible to secure a structurally strong and stable quality. Further, since the input / output connector is integrally disposed on the interface card body, the electric circuit can be stabilized.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the interface card of the present invention will be described below with reference to FIGS. In FIGS. 1 to 7, parts corresponding to those in the conventional example shown in FIGS. 8 to 11 are denoted by the same reference numerals, and detailed description thereof will be omitted.

In FIG. 1, reference numeral 5 denotes a connector on the computer side;
4 is an interface card main body, 15 is a thick part. An input / output connector 16 and a large electric component are attached to the thick portion 15.

The thick portion 15 is configured as shown in FIGS. 2 and 3 as a first embodiment. That is, the input / output connector 16 and the relatively large electric component 17 are installed at a predetermined portion of one end of the printed board 1. The electric component 17 is a lead component or the like that has connecting feet and has a height when mounted.

The input / output connector 16 on the printed board 1 and the electric component 17 are covered with a box-shaped frame 18 having no bottom. The frame 18 fixes the flange portion 18 a provided around the bottom opening to the printed board 1. Various integrated circuit elements 2 and other circuit elements 3 are mounted on the printed board 1, and the upper and lower surfaces of the printed board 1 are covered with a cover 6 to be integrally formed. The cover 6 disposed on the upper side of the printed board 1 is configured to cover up to the flange portion 18a of the frame 18.

Next, a second embodiment of the thick portion 15 will be described with reference to FIGS. This is an improvement of the structure of the frame. In this embodiment, the flat portion 19a of the frame 19 is placed on a predetermined portion of one end of the printed board 1.
Then, lead holes which penetrate both the frame flat portion 19a and the printed board 1 are formed, and the connection holes of the input / output connector 16 and the electric component 17 are connected to the printed wiring through these lead holes. To place. The frame 19 is formed in a box shape without an upper surface plate, and is formed by rising a vertical side plate portion 19b from a peripheral side portion of the flat plate portion 19a. Further, the frame 19 is formed with a flange portion 19c extending around the flat plate portion 19a.

Further, the integrated circuit element 2 and the other circuit elements 3 are mounted on the printed board 1, and the upper and lower surfaces thereof are integrated with the cover 6 over the flange 19c. At the same time, cover the upper opening of the vertical side plate portion 19b with the cover 2
It is configured to be closed with 0.

Next, a third embodiment of the thick portion 15 will be described with reference to FIGS. This is an improvement on the structure of the frame and cover. In this example, the flat plate portion 21 a of the frame 21 is placed on a predetermined portion of one end of the printed board 1.
Then, holes for leads penetrating both the frame flat plate portion 21a and the printed board 1 are formed, and the connection legs of the input / output connector 16 and the electric component 17 are passed through these holes to be connected to the printed wiring.

In the frame 21, a vertical wall portion 21b is erected integrally at a boundary portion between the normal thin portion and the thick portion 15 in the interface card body 14. At the same time, a flange portion 21c is formed integrally with the periphery of the flat plate portion 21a of the frame 21 so as to extend on the same plane as the flat plate portion 21a. Further, an integrated circuit element 2 and other circuit elements 3 are mounted on the printed board 1. Then, a cover 6 is attached to the lower portion of the printed board 1 so as to cover the printed board. As shown, the printed board 1 rises from the thin portion of the printed board 1 to the vertical wall portion 21b, and the thick portion 15
The cover 22 is formed so as to cover the upper surface of the cover 22 and to be bent downward from the upper side to cover the side surface of the free end.

In the interface card configured as described above, the connector 5 is connected to a computer (not shown), and the input / output connector is connected to a cable connector (not shown) to perform information processing such as writing and reading of information. Is what you do.

It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various other configurations can be adopted without departing from the gist of the present invention.
