ならず、双方の負担は比較的大きかつた。 Such printed board units have come to be used in larger sizes as electronic devices have recently become larger and have more diversified functions. Therefore,
Conventionally, relatively small-scale circuit changes, such as changing the read-only memory device mounted on a printed board unit and its wiring pattern, have been made on a printed board unit basis. Therefore, the manufacturer had to design and manufacture a new printed board unit in response to the change, and the user had to incur the cost, which placed a relatively large burden on both parties.

続結合が行えるようにすることを目的とする。 The purpose of this invention is to make it possible to easily attach and remove the sub-printed board from the main printed board, and to ensure that the sub-printed board is firmly held even when mounted.
The purpose is to enable sufficient connection and coupling between the main printed board and the sub-printed board.

達成される。 According to the present invention, a U-shaped mounting frame for holding the sub-printed board is arranged parallel to the main printed board, and both opening ends of the frame engage with the attachment/detachment handles of the sub-printed board. It has a U-shaped handle engagement part that protrudes to the outside, and a space slightly wider than the thickness of the printed board is placed between the two opposing inner sides of the frame so that the two opposing edges of the sub-printed board can be inserted. This is achieved by a printed board unit characterized in that a guide is provided with a plurality of protrusions in two rows, and a connector for inserting a sub-printed board is attached to the side opposite to the opening.

ことになる。 That is, the sub-printed board is mounted parallel to the main printed board by a U-shaped mounting frame that is mounted parallel to the main printed board, and the guide for its mounting is a projection on the opposite inner side of the frame. In addition, the frame has U-shaped handle engaging parts at both ends of the opening, so that when the sub-printed board is inserted into the frame, the handle for attaching and removing the sub-printed board engages with this engaging part. By mating, the sub-printed board is firmly attached to the frame, and the combination of the engaging portion and the handle provides insertion or removal force.

こ構造を有する。 In FIGS. 1 and 2, a printed board unit 1 is composed of a main printed board 2 and a sub-printed board 3 smaller than the main printed board 2. As shown in FIGS. The main printed board 2 includes a frame 4 for mounting the sub-printed board 3 in a predetermined manner, a plurality of circuit connection connectors 5, and a handle 6 for attaching and detaching the main printed board 2 to and from a shelf. The sub printed board 3 includes a connector 7 for connection to the circuit of the main printed board 2, and a handle 8 for attachment and detachment to the main printed board 2. The frame 4, which is U-shaped in plan view, has engaging portions 9 for handles 8 provided at each of the opposing opening ends, and attachment portions 9 for fixing to the main printed board 2 provided at three locations at the opening ends and the center. A tongue piece 10 and a plurality of protrusions 11 and 12 for guiding the sub-printed board 3 provided inside the two opposing sides are formed, respectively, and a connector 13 into which the connector 7 is inserted is fixed to the side opposite to the opening. It has been done. Note that the protrusions 11 and 12 are formed in the same plane, and the distance between the lower side 11a of the protrusion 11 and the upper side 12a of the protrusion 12 is made slightly larger than the thickness of the sub-printed board 3. Two opposing edges of the sub-printed board 3 are inserted. Also,
The handle 8 of the sub-printed board 3 has a lever structure for engaging with the engaging portion 9 of the frame 4 and applying an insertion force or removal force when the connectors 7 and 13 are attached or detached.

It is composed of an external line connector 21 and the like attached to 20. In such a shelf 15, from the front opening side, there is a printed board unit 1 whose two opposing edges fit into the grooves of the vertically opposing rails 17.
(Main printed board 2) is inserted. Note that the handle 6 has the same structure as the handle 8, and engages with the groove 22 of the member facing upward and downward in the front surface of the frame body 16, so that when the connector 5 is connected to and removed from the connectors 18 and 21, the insertion or removal force is applied. It has a lever structure that gives it strength.

ることができる。 In such a printed board unit 1, for example, if a read-only memory device is mounted on the sub-printed board 3 and the required wiring pattern is formed, it becomes necessary to increase the capacity of the read-only memory device at a later date. If this occurs, the circuit formed on the main printed board 2 can be used as is, and only the small sub-printed board 3 can be updated to meet new demands.

省略したものでもよい。 In the above embodiment, one main printed board is equipped with one sub-printed board.
A plurality of sub-printed boards may be mounted on one main printed board. In that case, one sub-printed board may be incorporated into the current circuit, and the other sub-printed board may be installed as a spare. Further, although a connector is attached to the sub-printed board, a card edge type printed board may be used and the connector may be omitted.
