Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field of the Invention The present invention relates to a printed board shelf into which printed boards each having a common lot connector mounted thereon are inserted in parallel.

(b) Background of the Technology In recent years, electronic devices have been miniaturized by mounting components on printed boards at high density and by arranging many of these printed boards in parallel on shelves. As a result, each input/output circuit cannot be configured only from the rear plate surface of the shelf, so connectors are mounted on the front edge of the printed board while it is inserted into the shelf.

(C) Prior art and problems The conventional shelf into which this type of printed circuit board is inserted has a box-shaped structure with connectors arranged side by side on the rear panel and guides provided opposite to the upper and bottom plates. be. Then, a printed board is inserted into each guide and connected to the corresponding connector on the rear board.

In addition, cable connectors are mounted in parallel on the long band-shaped flanged pulley that is the common lotus line. Each of these cable connectors is inserted into each of the common bus connectors mounted on the front edge of the printed board after the printed boards are inserted in parallel on the shelf.

In addition, in order to prevent the printed circuit board from being pulled out due to equipment vibration, or from poor connector contact, secure both ends to the front of both side plates with screws, etc. on the opening side of the shelf. A long and narrow holding plate is installed. This holding plate is constructed so that the side surface on the printed board side presses the front edge of each printed board.

However, if a problem occurs with the printed board and the printed board is to be removed from the shelf for maintenance or inspection, the holding plate must first be removed. Then, after disconnecting the cable connectors attached to the printed board to be removed and the many printed boards adjacent to it from the common bus connector, and removing the flat cable from the opening side of the shelf, the printed board must be removed. There is such an annoyance.

Also, when the device is in operation, the flat cable hangs down from the front of the shelf, which not only spoils the aesthetics, but also risks getting your hands caught on this flat cable and damaging the device.

(d) Object of the Invention An object of the present invention is to provide a printed board shelf in which the above-mentioned conventional problems are eliminated.

(e) Structure of the Invention In order to achieve this object, the present invention provides an external line connector that is attached to the rear edge of the shelf, which is inserted into the connectors arranged in parallel on the rear panel of the shelf, and a common hub attached to the front of the upper edge. A printed board with a connector attached thereto, and a side plate of the shelf main body that is higher than the height of the printed board as desired, a guide is formed on the bottom plate, and a rear middle board parallel to the bottom plate is attached to the rear of the upper edge of the printed board. A shelf main body in which a guide is formed into which the printed board is inserted, and a slit into which the front advancing part of each printed board is inserted and engaged are formed in the front upper part of the shelf main body, which is arranged in parallel with a retaining plate part parallel to the bottom plate. The flat cable, which is a common lotus, is housed above the printed board and behind the front board.

In Fig. 1, the pair of shelf main body side plates 1 have a height of 1-board (printed board 14 in Fig. 2).
It is a metal plate that is desirably higher than the height of , and whose depth is approximately equal to the length of the printed board. Each shelf body side plate 1
A fixing plate 2 is formed at the upper part of the front side of the housing, and is cut and raised inward at right angles to form a vertical surface. This fixing plate 2 is provided with a hole in which a convex surface of a front plate 10, which will be described later, comes into contact with and into which a locking latch 13 is engaged and fitted.

The bottom plate 3 of the shelf body is made of a metal plate, and is provided with two parallel protrusions on the front and back sides of the shelf that are plate-shaped when viewed from the side. The convex portions are cut at equal pitches to form guide grooves 4 perpendicular to the front surface of the shelf. This bottom plate 3
is fixed to the lower part of the shelf main body side plate 1 by, for example, spot explosion welding.

A rear plate 5 having a height substantially equal to the height of the printed board is fixed to the rear surface of the shelf side plate, and connectors 7 are arranged in parallel on the inner surface of the rear plate in correspondence with the respective guide grooves 4. Reference numeral 6 denotes a middle plate having a width sufficiently shorter than the length of the printed board, and is provided with a platform-shaped protrusion parallel to the front surface of the shelf when viewed from the side. The convex portions are cut at equal pitches to form guide grooves 6a perpendicular to the front surface of the shelf. This middle plate 6 is mounted at the rear of the shelf main body side plate 1 at a position at the height of the rear face plate 5, parallel to and facing the bottom plate 3, and both ends thereof are fixed to the shelf main body side plate 1.

A front plate 10 having a height in front view that is desirably larger than the difference in height between the shelf side plate 1 and the printed board and having a channel shape in side view.
The front portion thereof is parallel to the upper edge and protrudes inward in a trapezoidal shape to form a convex surface portion 10a. Holes into which locking latches 13 are fitted are provided near the ends of both sides of the convex surface portion 10a, corresponding to the holes in the fixing plate 2. In addition, in the retaining plate part 11 which is the lower surface of the front plate 10, slits 12 are provided in parallel, corresponding to the guide grooves 4, into which the upper front edges of each of the printed boards inserted on the shelf are inserted and engaged. It is being
