In addition, it is necessary to tighten screws to fix and hold the printed circuit board, which requires spacers and metal fittings, increasing the number of parts and increasing costs. Secondly, the spacer for receiving the tightening screw is required in a specific portion of the printed circuit board, so that electronic parts cannot be mounted in this portion and so-called dead space is generated. Thirdly, there is a problem in that a horizontal connector cannot be attached to the screw tightening portion due to the above space.

生じない。Before the printed circuit board is inserted, the ridges have a mountain-shaped cross section of a series of linear lines, and the gap between the mountain-shaped top and the wall surface of the guide rail facing the mountain-shaped top is the same as that of the printed circuit board to be inserted. It is formed to be slightly smaller than the thickness. When the printed circuit board is inserted in this state, the chevron top is crushed by the insertion pressure at this time, and the printed circuit board is properly held between the ridge and the guide rail wall facing it along the direction orthogonal to the printed circuit board. It will be clamped and held by force. In addition, the substrate does not bend because it is a continuous line.

る。FIG. 1 is a front view of a printed circuit board storage case according to the present invention. In the figure, guide rails 34, into which a plurality of printed circuit boards 32 are inserted and held, are provided on inner wall surfaces 30-1 and 30-2 of the housing 30 which face each other. The guide rails 34 are generally made of resin, and the housing 30 is made of a metal plate or resin. And the housing 30
When is made of a metal plate, the guide rail 34 is fixed by forming a mounting hole in its side wall, and when it is made of resin as in this embodiment, it is formed integrally with the housing 30.
本考案の特徴的なことは、前記ガイドレール34のプリン
ト基板挿入路に挿入方向に沿い断面山形の突条部を部分
的に設けられていることである。What is characteristic of the present invention is that the printed circuit board insertion path of the guide rail 34 is partially provided with a protrusion having a chevron cross section along the insertion direction.

能である。That is, in this embodiment, as shown in FIG. 2 (a), the board insertion path is the upper guide 34a of the guide rail 34.
And the lower guide 34b and the inner wall of the housing 30. The protrusions 36 are provided near the end of the lower guide 34b along the insertion direction of the printed circuit board 32. This ridge 3
6 is made of a resin such as polyacetal or polypropylene, and has a chevron cross section and has a plan view as shown in FIG. 2 (b). Then, the starting end portion thereof is formed in a sloping slope portion 36a along the insertion direction so that the printed circuit board 32 can be easily transferred. Top 3 of this ridge 36
The height of 6b can be constant along the longitudinal direction, or can be formed so as to gradually increase in the depth direction.
このように、頂部36bの高さを漸増させることで、プリ
ント基板32の挿入を容易にするとともに、挿入完了時点
においてより強固にプリント基板32を保持することがで
きる。In this way, by gradually increasing the height of the top portion 36b, it is possible to facilitate the insertion of the printed circuit board 32 and more firmly hold the printed circuit board 32 when the insertion is completed.
なお、頂部高さが低い部分では底面の幅を広く、反対に
高い部分では底面の幅を狭くして突条部36の安定を図る
ことが好ましい。In addition, it is preferable that the width of the bottom surface is wide at the portion where the height of the top is low, and the width of the bottom surface is narrow at the portion where the height of the top is low to stabilize the ridge portion 36.

となる。In the embodiment of the present invention having the above construction, before inserting the printed circuit board, as shown in FIG. 3 (a), there is a gap t'between the lower surface of the upper guide 34a and the top 36b of the protrusion 36. However, when the printed circuit board 32 is inserted, as shown in FIG.
b is crushed, which causes the printed circuit board 32 to move to the upper guide 32a.
Thus, the ridge portion 36 and the ridge portion 36 are clamped and held with an appropriate elastic force.

するという恐れもない。As described above, according to the embodiment of the present invention, the printed circuit board is clamped and held in the vertical direction by the guide rails, so that the circuit board is not bent and therefore electronic components are mounted. No stress is generated in the soldered part, which is excellent in reliability, and does not cause problems such as poor contact. Further, since the guide rail is provided only with the ridge portion, the above effect can be achieved at low cost. Furthermore, since the elastic force of the printed circuit board itself is not used to fix the printed circuit board as in the conventional case, there is no fear that looseness will occur due to aging.

Therefore, the reliability can be improved. Further, since the height of the ridge portion is gradually increased from the front surface of the housing toward the rear portion, the board can be easily inserted.
