Description

[Detailed description of the invention] The present invention relates to an inter-card connection structure.

Conventionally, a structure has been adopted in which a connection mechanism is provided between the cards and a connector is interposed between the cards having electronic components mounted on a printed circuit board. 1st to 3rd
The figure shows such a conventional *m structure.

In FIG. 1, connection pads 3 and 4 are formed on opposing surfaces of a first card 1 and a second card 2, and a pressure contact type connector 6 equipped with a connection spring 5 connects the connection pads 3 and 4.
4 shows the structure that connects the two.

In such a conventional II connection structure, since the connector 6 needs to be provided with the connection spring 5, it is difficult to narrow the space between the cards 1 and 3 in order to obtain appropriate spring characteristics. If the distance between the cards 1 and 2 is long, there is a drawback that high-speed signal transmission cannot be performed. Ninth, the connecting pads 3 and 4 are rounded on the side opposite to the component mounting side, which requires extra man-hours to manufacture the card and increases the price. Furthermore, since it is necessary to provide an anti-curl mechanism to prevent one card 1.2 from warping, the card inevitably becomes heavy in weight.

In the conventional example shown in FIG. 2, the structure of the card 1 is the same as that in FIG. 1, and the card 2 has a through hole 7.
The connector 9 is connected to the through hole 7 of the card 2 by the pin 8.
It has a structure in which it is connected to the connection pad 3 of the card 1 by a connection spring 5. This case also has the same drawbacks as the conventional example shown in FIG. 1, except that the card 2 does not have a warpage prevention mechanism.

The conventional example shown in FIG. 3 is a through hole 7KK of card 1.
The tip end 11 of the M connector 12 is connected, and the male connector 10 is connected to the through hole of the card 2. Then, by fitting the female connector 12 and the male connector 10, the distance between the cards 1 and 2 is 11! The structure continues. In this case as well, it is difficult to narrow the space between the cards 1 and 2, and the structure of the connector becomes very complicated.

The purpose of the present invention is to solve the above-mentioned conventional drawbacks and to
, 2, and provides an inter-card connection structure that is easy to insert and remove.

In the connection structure of the present invention, electronic components are mounted on a printed circuit board, the first and second cards are stacked, and connection bins are respectively provided upright at positions where they touch each other when in good condition.
An insertion hole is formed in the card at the 9th position corresponding to the connection bottle installed upright on the second card, and when the two cards are stacked, the second card The connection pin penetrates the insertion hole of the first card, stands upright on the first card, and is configured to protrude adjacent to the nine connection pins, and the connection pin protrudes adjacent to the W/4 connection pin. The present invention is characterized in that it is provided with a socket for connecting the connection bins of the cards No. 1 and IIK2, and the connection between the first and second cards is made through the socket.

Next, one embodiment of the present invention will be explained in detail with reference to the drawings.

Figure 4 is a perspective view showing one embodiment of the present invention.
51st Company A perspective view showing the O-shape m after assembly, and FIG. 6 is a sectional view taken along line A-7 in FIG. 5. In these figures,
Card 1 has a connection bin 13 erected, and card 2 has a card lo connection pin 1sKW4 when stacked with card 1 and in good condition.
The connection bin 14 is set upright at a position of 1.m. Connection bin 140
The base is molded with a mold 15. The height of the mold 15 is arbitrarily formed to maintain the cards 1, 2 at the appropriate m-. Then, an insertion hole 16 is drilled in the power door 1 at a position facing the connection bin 14. Therefore, when the cards 1 and 2 are stacked, the bottle 14 passes through the insertion hole 16 and projects to the upper surface of the card 10 in the drawing. And connector 17
This is the structure for connecting the connecting bins 14 and 13.

As clearly shown in FIG. 5, the connector 17 has a built-in connection spring 18 and can connect the bins 13 and 14.

In this embodiment, the distance between the cards 1.2 can be arbitrarily set depending on the height K of the mold 15, and can be made extremely narrow.

That is, it is possible to improve the signal speed. In addition, since the bins 13 and 14 are connected by the connection holes 18 and 18, there is no need to press the connection springs at the card 1 and 2 connections as in the conventional case.In other words, the cards 1 and 2 are specially designed to prevent Since there is no need for a mechanism, it is lightweight and easy to carry. In addition, since the positions of the bins 13 and 14 can be arbitrarily selected on the card and it is easy to arrange a large number of bins, the connector 17 is used as a connector for connecting pairs of a plurality of connecting bins. is easy. That is, since it can be a multi-pole connector, the connection between the cards 1 and 2 is completed by one insertion and removal. There is no problem in dividing the number of connection bins of the connector 17 appropriately. Accordingly, the force required for inserting and removing the connector can be appropriately set.

As described above, in the present invention, connection bins are installed in adjacent positions on two cards, and one connection bin is drilled in the other card and passes through the mourning hole to connect the other card. Make the bottle protrude by ml, and this adjacent protrusion 91
Since the pair of connection bins are connected to each other by a connector, the distance between the two cards can be reduced, which has the effect of improving the signal speed. In addition, the card is lightweight and has a simple structure and does not require excessive pressing force.
