上・下ガイド溝間の精度向上に好適なものに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to the structure of a guide rail for a printed circuit board, and particularly to one suitable for improving the accuracy between upper and lower guide grooves.

工では不可能となった。The guide rail structure of the conventional printed board was developed in Japanese Patent Application Laid-open No. 1983-
As described in Japanese Patent No. 33899, a guide rail was attached to the mounting plate, and the guide groove was provided with a constant wall thickness. Therefore, jigs and tools are required to achieve dimensional accuracy between the upper and lower guide grooves of the printed board, and workability has not been taken into consideration. On the other hand, printed boards have become larger,
Due to high-density packaging and narrower pitches, sheet metal drawing is no longer possible.
本発明の目的は、プリント板のガイドレールの上・下問
寸法精度をガイドレール取付板側で設定可能とする構造
を提供することにある。An object of the present invention is to provide a structure in which the upper and lower dimensional accuracy of the guide rail of a printed board can be set on the guide rail mounting plate side.

。したがって、発熱量の少なく部品高さも低いパッケー
ジについてはプリント板の実装ピッチを２分の１にする
必要が生じた。このため従来の板金絞り加工では加工不
可能となり。As electronic devices become more densely packed, it is no longer possible to improve the performance of printed circuit boards using conventional equidistant pitches. Therefore, for packages with low heat generation and low component height, it has become necessary to reduce the mounting pitch of the printed circuit board by half. For this reason, it cannot be processed using conventional sheet metal drawing processing.

要もあった。Although we decided to use resin molding, the dimensions between the upper and lower guide rails were also limited in order to improve the connector mating accuracy between the motherboard and the package and to achieve high-density mounting. Furthermore, for forced air cooling, it was necessary to increase the area of the opening as much as possible.
これらの理由により、従来の実装スペース内に収才るこ
とを前提として本発明はなされた。For these reasons, the present invention was developed with the premise that it would fit within the conventional mounting space.
すなわち、上下ガイド溝間の寸法精度を向上させるため

けたことを特徴とするものである。That is, in order to improve the dimensional accuracy between the upper and lower guide grooves, the guide groove is provided on the same surface as the guide rail mounting plate.

なっている。An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. A printed board 1 on which electronic components are mounted is inserted along upper and lower guide rails 4 attached to upper and lower supports 2, and a certain distance is provided between the guide rails. It has a structure in which the printed board 1 can be easily inserted.

A chamfer 7 is provided at the mating part with the support, allowing the printed board to be inserted smoothly.Furthermore, a cooling air hole 8 is provided to allow cooling air to pass through.The material is generally made of plastic, but conductive plastic is also used. Needless to say, its use is also effective in preventing static electricity.
本発明によれば、従来のプリント板の実装寸法を変える
ことなく、ガイドレールの上・下問の寸法精度を上げる
ことができるので組立精度を向上する効果がある。According to the present invention, it is possible to improve the dimensional accuracy of the upper and lower parts of the guide rail without changing the mounting dimensions of the conventional printed circuit board, which has the effect of improving the assembly accuracy.
