ある。(b) Prior art In electronic equipment such as tape recorders or radio receivers, one printed circuit board cannot be made very large due to space limitations, so each electrical component is divided into two or more printed circuit boards. is installed. In this case, when the printed circuit boards are stored in a cabinet, they are mounted one on top of the other, but in this case, the printed circuit boards have printed wiring and many electrical components attached to them. Therefore, it was necessary to provide a space between the printed circuit boards. Conventionally, therefore, a cylindrical spacer was inserted between the printed circuit boards to secure the spacer, but in order to install the spacer, the spacer had to be held down by hand and then screwed on. It took a while to install. Furthermore, it is described in Japanese Utility Model Publication No. 11545/1983 that the printed circuit board is separated and installed in two stages using conductive eyelets and metal rods, and the conductive patterns of the printed circuit board are electrically connected. , the eyelet needs to be soldered to the conductive pattern, so
It is not suitable for simply mounting printed circuit boards one on top of the other.

とともにキヤビネツトに取付けられる。 Next, a method of using the printed circuit board mounting device of the present invention will be explained. A spacer 3 is inserted into a mounting hole 2 at a corner of a printed circuit board 1 to which electrical parts and the like are previously mounted. In this case, if the claws 4, 4 of the spacer 3 are positioned at the large diameter part of the mounting hole 2, and if you press the outer circumference with some force, the upper part of the spacer 3 will bend slightly due to the cut grooves 6, 6. , the claw pieces 4, 4 of the spacer 3 are inserted into the mounting hole 2 from below,
The spacer 3 is attached to the printed circuit board 1 by sandwiching the printed circuit board 1 between the claw pieces 4, 4 and the shoulder portion 8 located on the small diameter portion of the mounting hole 2. In order to mount the printed circuit board 1 on other printed circuit boards 9 in multiple layers at intervals, the printed circuit board 9 is inserted into the screw hole 11 of the boss 10 formed in the cabinet 12, as shown in FIG. 3 or 4. Then, place the lower end of the spacer 3 so that the mounting holes of the printed circuit board 9 are aligned with each other. Thereafter, a screw 13 having a slightly smaller diameter than the through hole 5 of the spacer 3 and sufficiently longer than the through hole 5 is passed through the through hole 5 of the spacer 3. The screw 13
strongly hits the small diameter part of the through-hole 7 and pushes the claw pieces 4, 4 to expand, so the claw pieces 4, 4 are strongly contacted with the inner wall of the mounting hole 2 of the printed circuit board 1, and the spacer 3 is attached to the printed circuit board 1. It can be firmly installed without wobbling. Moreover, since the screw 13 is screwed into the boss 10, the printed circuit board 1 is spaced apart from the printed circuit board 9, and the printed circuit board 9 is
It is installed in the cabinet with the
