Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printed wiring board storage rack, and more particularly to a printed wiring board storage rack in which connectors can be easily attached to the back plate (motherboard) of the rack and wiring is easy.

A conventional printed wiring board storage rack using a so-called wrapping type connector is shown in FIG. Insert the pin (called a pin),
With back plate 1 and connector 2 in close contact with each other,
The connector 2 is attached to the back plate 1 by dipping the outer surface of the connector in molten solder and soldering the pins 3, 3, and cutting the pin tips as necessary.

By the way, since the back plate 1 is attached to the rack body 10 consisting of the top plate 4, the bottom plate 5, and the side plates 6, 6, external input/output connectors other than the connector 2, such as the terminal block 7, are attached to the back plate 1. must be attached to the outside surface of the
Since the attachment must be done by so-called manual soldering other than the solder dipping described above, reliability is reduced.

In addition, it is difficult to provide all the wiring patterns for connecting connectors 2, 2 and external input/output connectors on the back plate 1 when there are many inputs and outputs, so after removing connectors 2, 1, must be removed and wired to the outer surface of the back plate, which requires a complicated soldering process.

Furthermore, when the length of the connector 2 is close to the width of the back plate 1 in the vertical direction, the back plate is dipped in the molten solder.
There are various inconveniences such as difficulty in attaching a jig to prevent thermal deformation.

. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a printed wiring board storage rack in which connectors can be easily attached to a back plate and wiring can be easily performed.

Embodiments of the present invention will be described below with reference to FIGS. 2 to 4.

FIG. 2 (here, reference numeral 1 indicates the back plate, and reference numeral 2 indicates the connector, and only the free ends of the pins 3, 3 of the connector 2 are inserted into the pin holes of the back plate 1. Therefore, An appropriate gap is maintained between the back plate 1 and the connectors 2, 2.

The distance between the back plate 1 and the connectors 2, 2 is preferably such that it is not necessary to cut the tips of the pins 3, 3 protruding from the outer surface of the back plate 1.

For connectors 2 and 2 that need to be wired together, use a jig or the like before inserting the free ends of the pins 3 and 3 into the pin holes in the back plate 1 and temporarily fixing them to the back plate. The terminals are temporarily fixed to each other using the terminals 3 and 3, and are connected to each other via connecting conductors 8, 8 whose ends are wrapped around the required pins 3, 3.

. The back plate 1 to which the connectors 2, 2 are temporarily attached is dipped on its outer surface in molten solder, so that the free ends of the pins 3, 3 are soldered to the back plate 1 1, and 7 as described above. The back plate 1 to which the connectors 2, 2 are attached is connected to the connector 2,
It is attached to the rack main body 10 so as to cover the rear opening of the rack main body 10 with 2 facing inside.

Further, when mounting, the connectors 2, 2 may be mounted on the rack body.

Note that when it is necessary to provide an external output connector such as the terminal block 7 (see Figure 1), it is necessary to place these at predetermined positions on the inner surface of the back plate 1 and solder them. If a certain portion is made to protrude from the outer surface of the back plate, it can be soldered simultaneously with the connectors 2, 2 when immersed in the molten half EB.

The printed wiring board storage rank according to the present invention configured as described above has considerable rigidity as each connector 2 is supported by a large number of pins 3.3, and the socket portion of the connector 2 is in close contact with the back plate. At least, there is no problem in inserting and removing the printed wiring board 9 (see FIG. 1).

In addition, the communication conductor 8 is used to exchange signals between the connectors.
, 8, connection with an external circuit is made by the wiring pattern on the back plate 1 and the external output connector connected thereto.

FIG. 3 shows another embodiment of the present invention, in which a flat cable 11 is provided in the gap between the back plate 1 and the connector 2.
The terminals of the cable connector 12 are also soldered to the wiring pattern on the back plate 1 when immersed in molten solder.

FIG. 4 shows still another embodiment of the present invention, in which a power bus bar 13 is provided in the gap between the back plate 1 and the connectors 2, 2, and the connectors 2, 2 are melted at the same time. Soldering can be achieved by dipping into solder4.

As is clear from the above explanation, the present invention
, 2 and the back plate 1 (Since the - connector is attached to the back plate, this gap can be used to wire between the connectors 2, 2, and this Wiring devices such as external input/output connectors can be provided in the gap.

Therefore, complicated wiring can be easily done without the Senju F (+ process).

In addition, since there is no need to cut the free ends of the bottles 3, 3 after dipping the outer part of the back plate 1 in the molten liquid [E] as in the conventional case, the connectors 2, 2 can be attached to the back plate 1 easily. This has various effects such as making it easier.

In the illustrated embodiment, the cross-sectional shape of the pin 3 is circular, but it goes without saying that it may be rectangular.
