DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a memory card connector, a memory card mounting method, a memory card connector mounted body, and a memory card mounted body.

[Background of the Invention] In recent years, miniaturization and thinning of personal computers (especially notebook personal computers) have been rapidly progressing. As a result, the size of the internal substrate has become smaller, and it has become an issue how to achieve high-density mounting by using components with a small mounting space for each component.

Had been 3 to 5 are diagrams for explaining a conventional mounting of two memory cards. FIG. 3 is an exploded view of an example of a conventional memory card connector having two headers 32 and two "U" -shaped frames 31 corresponding to the headers.

[0004] In the case of a plate-shaped memory card having a substantially rectangular cross section in the plane direction, in the conventional technique, two "U" -shaped frames for mounting one memory card are used. Were mounted in parallel on a plane. In this case, the screwed portion is shared, or the screwed portion is shifted so that the width in the width direction (in the direction in which the short edge of the plate-shaped memory card having a substantially rectangular cross section extends) is reduced as much as possible. It has been reduced.

For example, as shown in FIG. 3, a U-shaped frame 31 is mounted on each of two headers 32 provided on a substrate 33, and the two
Is fixed to the substrate 33 by screws. The “U” -shaped frame 31 is composed of three edges (one short edge and two long edges on both sides sandwiching the edge) of a plate-shaped memory card having a substantially rectangular cross section in the plane direction. "Co" that bends in response to
The frame is shaped like a letter.

FIG. 4 shows two U-shaped frames 31 fixed in parallel on the flat surface of the substrate 33 as described above. FIG. 4A shows the substrate 33.
The two headers 32 and the two "U" -shaped frames 31, which are conventional memory card connectors secured in parallel adjacent to the flat surface of the board 33, are oriented in a direction perpendicular to the flat surface of the substrate 33. FIG. FIG. 4B is a view of two “U” -shaped frames 31 fixed in parallel and adjacent to the flat surface of the substrate 33 as viewed from the direction of inserting the memory card. . Note that reference numeral 46 is
The memory card inserted into the frame 31 having a “U” shape is shown.

[0007] As another conventional memory card connector, there has been one using a memory card mounting plate-like member 51 as shown in FIG. 5 instead of the "U" -shaped frame 31. FIG. 5A shows a conventional memory card connector, two headers 52 and two memory card mounting plate members 51 fixed in parallel and adjacent to a flat surface of a substrate 53, and the same. FIG. 3 is a view as seen from a direction perpendicular to a flat surface. FIG. 5B shows the substrate 5
FIG. 11 is a view of two memory card mounting plate members 51 fixed in parallel and adjacent to the flat surface of No. 3 when viewed from a memory card insertion direction.

Conventionally, for example, as shown in FIG.
When the memory card mounting plate-like members 51 are arranged and fixed on the flat surface of the substrate 53 on each of the two headers 52 provided on the three, the space between the two memory card mounting plate-like members 51 is fixed. In some cases, the screwing portion is shifted so that the width in the lateral width direction of the memory card (the direction in which the short edge of the plate-shaped memory card having a substantially rectangular cross section in the plane direction extends) becomes shorter. Reference numeral 56 denotes a memory card to be inserted.

It has a frame 5. The substantially “Y” -shaped frame 4 can mount two memory cards.

The central guide frame 5 is an integrated central guide frame portion having a memory card mounting space on both sides, and has two memory card mounting spaces for each memory card mounting. It is an integrated central guide frame that partitions into a space. The guide frame 5 at the center has a guide rail structure on both sides (right and left) on which a memory card can be mounted, and two memory cards can be mounted on both sides.

That is, although the guide frame 5 at the center is one integrated guide rail, the insertion of a memory card (insertion of a memory card) into one of the sides of the guide frame 5 at the center, and In addition to enabling the guidance, the memory card can be inserted and guided on both sides of the center guide frame 5.

The header 2 and the leading end of the memory card each have a connecting portion for mechanically and electrically connecting to each other. The memory card is pushed in the direction in which the header 2 is present from the memory card mounting slot 7 in parallel with the substrate 3, and the connection portion of the leading end portion of the memory card with the header 2 is connected to the header 2 and mounted. The portions 4a and 4b in the substantially "Y" -shaped frame 4 are frame portions for taking out the mounted memory card. When the memory card is loaded, the button 4a at the tip
It is rotated approximately 90 ° to the position a ′.

When removing the inserted memory card, the leading button 4a is rotated by about 90 ° from the position 4a 'to the position 4a, and the leading button 4a is pushed in the direction in which the header 2 is present. The portion 4b moves in the direction in which the header 2 exists, and the leading end of the memory card can be removed from the header 2 and taken out. Although the portions 4a and 4b are movable portions, they are configured so as not to be separated from the substantially "Y" -shaped frame 4 before being fixed to the substrate 3 by screws.

In order to mount the memory card connector on a board, for example, as shown in FIG. 1, two headers 2 are provided in parallel on a board 3 and two headers 2 provided on Is mounted, and the substantially frame-shaped frame 4 is fixed to the substrate 3 with screws. Thus, the header 2 and the substantially “Y” -shaped frame 4
Is fixed to the substrate 3 as shown in FIG.

[Second Embodiment] A substantially "Y" -shaped frame 4
May be separated separately. For example, when the substantially “Y” -shaped frame 4 is separated into two separators A and B, one of the separators A includes the guide frame 5 at the center (for example,
The other is a separator B (for example, a substantially "L" shape) without the central guide frame 5 and the other is a memory card connector. When mounted on a substrate, they can be mounted side by side on a substantially “Y” -shaped frame.
