る。Conventional structure and its problems Generally, when transporting finished or semi-finished electronic devices, the connection leads of tall or large parts assembled on a printed circuit board may be damaged due to vibrations during transport. There is a risk of damage. For this reason, the lower surfaces of these components and the printed circuit board are usually fixed with a bond or the like to prevent the parts from wobbling.

ｂを設けたものである。 One such component is an aluminum electrolytic capacitor with an explosion-proof valve. This is the first
As shown in Figures a and b, the main body 1a is sealed with aluminum, the connection leads 2, 2 are drawn out from the bottom surface, and the explosion-proof valve 1 is inserted between these connection leads 2, 2.

定強度が得られないという問題がある。 When such an aluminum electrolytic capacitor 1 with an explosion-proof valve is to be fixed to a printed circuit board, the bond must be applied with great care so that the adhesive fixing bond does not adhere to the vicinity of the explosion-proof valve 1b. Also, the range to be fixed with bond,
Since it is limited to parts other than the explosion-proof valve 1b, there is a problem that sufficient fixing strength cannot be obtained.

十分に発揮させることができる。Structure of the Invention The present invention provides an explosion-proof hole consisting of a long hole or a plurality of round holes in the vicinity of an explosion-proof valve on a printed circuit board,
The entire lower surface of the capacitor body is adhesively fixed to the printed circuit board. In this way, by bonding the entire lower surface of the main body, including the explosion-proof valve, to the printed circuit board with a bond or the like, the capacitor itself can be fixed sufficiently firmly, and there is no need to pay close attention to the position where the bond or the like is applied. Moreover, since the explosion-proof hole is provided near the explosion-proof valve, the pressure when the capacitor explodes is reduced through the explosion-proof hole. As a result, parts do not fly off, and the printed circuit board does not crack due to the pressure of an explosion, allowing the explosion-proof valve to perform its functions to its fullest.

In FIGS. 2 and 3, parts having the same functions as those in FIG. 1 are denoted by the same reference numerals, and explanations thereof will be omitted. 3 is a printed circuit board, which has insertion holes 3a, 3a for inserting connection leads 2, 2;
It has an explosion-proof hole 3b consisting of a long hole provided between the insertion holes 3a, 3a. 4 is bond and 5 is solder.

固定する。 In the above configuration, when the connection leads 2, 2 are inserted into the penetration holes 3a, 3a and soldered to the copper foil (not shown) provided on the bottom surface of the printed circuit board 3, the explosion-proof valve 1b is placed near the explosion-proof hole 3b. To position. Thereafter, a bond 4 is applied to the entire lower surface of the main body 1a of the capacitor 1, and the capacitor 1 is adhesively fixed to the surface of the printed circuit board 3.

ボンド４の塗布位置にも注意を払う必要がないた
め、作業性もよくなる。 In this way, when the capacitor 1 explodes, the pressure is reduced through the explosion-proof hole 3b, so troubles such as parts flying off or the printed circuit board 3 cracking can be prevented. Moreover, since the entire circumference of the bottom surface of the capacitor 1 is adhesively fixed with bond 4, the capacitor 1 can be firmly fixed, and at the same time,
Since there is no need to pay attention to the application position of the bond 4, workability is also improved.
なお、上記実施例では防爆穴を長孔で構成した
が、多数の丸孔等で構成してもよい。 In the above embodiment, the explosion-proof hole is formed of a long hole, but it may be formed of a large number of round holes.
