DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card-like adapter for electrically connecting a small and thin card to a connection slot for a standard-sized memory card provided in a main unit such as a personal computer.

[0002]

2. Description of the Related Art Heretofore, small and thin cards which are mounted on a digital camera or the like and used for storing photographed image data are commercially available. It has a thickness of about 0.8mm, as shown in the exploded, perspective, and schematic view of the card-shaped adapter in FIG.
A small and thin card 30 having a size of about 35 mm × about 45 mm and having a surface exposed terminal 31 is known. The small thin card 30 is loaded into a camera and photographed to store image data. The image data is removed from the camera, and the stored image data of the removed small thin card 30 is sent to an external device (not shown) such as a personal computer. Displaying a captured image on a display unit of a device is often performed.

However, a card insertion connection mechanism provided in an external device such as a normal personal computer has a width of about 54 mm.
It is a size suitable for a so-called standard size memory card for a personal computer having a length of about 86 mm x about (3.3 to 5.0) mm, and the number of pins of the external connection terminals 27 is also the same as that of the standard memory card. Therefore, it is difficult to directly insert and connect the small thin card 30 to a card insertion connection mechanism provided in the external device.

Therefore, the outer shape and the external connection terminal 2
The shape of 7 is the same as the shape of a standard size memory card for a personal computer, and the small thin card 30 is concealed and stored, and the small thin card 30 and an external device such as a personal computer are interposed therebetween to electrically connect both. A card-like adapter 2 having a configuration that allows connection is required.

As shown in FIG. 3, in the conventional card-shaped adapter 2 for a small and thin card, the frame 21 has a pair of long side frames 21a and 21b of the card-shaped adapter 2 and a substantially central portion of the side frame. A central frame 21c perpendicular to the frame, an end frame 21d and a bottom frame 21e also perpendicular to the side frame at one end of the side frame.
It consists of

[0006] The small thin card storage portion 23 is composed of the bottom portion 23a and the lid portion 23b, each of which is composed of a part 21a ", 21b" of the long side frame, the center frame 21c, an end frame 21d, and a bottom frame 21e. Are formed in combination.

A plurality of small and thin card connector pins 25 are arranged on the bottom frame 21e, and the lead portions 25a are led out of the through holes 22. In this state, the bottom 23a and the lid 23
When b is combined, the small thin card insertion slot 24 is formed and the connector pin 25 is fixed.

In the remaining space of the card type adapter 2, a circuit board 26 and terminals 27 for external connection of the card type adapter are incorporated, and are provided between the lead portion 25a and the circuit board 26, and between the lead board 25a and the circuit board 26. The external connection terminal 27
And solder connection between them. The card-like adapter 2 for a small and thin card was obtained by covering both sides of the card-like adapter core thus assembled with thin metal plates 29a and 29b such as stainless steel.

[0009]

However, since the conventional card-type adapter has a very asymmetric shape including a pair of side frames, a center frame, an end frame, and a bottom frame, the metal adapter for integrally forming the same is used. Since the structure of the mold becomes extremely complicated, there is a problem that the design work becomes complicated and the cost of the mold becomes expensive.
