本発明は、防水機能を有する電子機器に関するものであ
り、特に室外で使用される電子機器の防水構造を提供す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic device having a waterproof function, and particularly provides a waterproof structure for an electronic device used outdoors.
従来、防水機能を有する電子機器は第１図、第２図に示
すように電子回路６を収納したケース本体１と上蓋２と
の間に、平板状の防水バッキング３ａを介在させるか（
第１図）、Ｑリング３ｂを介在させて（第２図）２本体
１と上蓋２とをビス４により締め付ける構造をとってお
り、ケース本体１内に水が流入するのを防止している。Conventionally, electronic devices having a waterproof function have either had a flat waterproof backing 3a interposed between a case body 1 housing an electronic circuit 6 and a top cover 2, as shown in FIGS. 1 and 2.
(Fig. 1) and Q-ring 3b (Fig. 2) are used to tighten the main body 1 and the top cover 2 with screws 4, thereby preventing water from flowing into the case main body 1. .
しかしながら、このような構造の電子機器においては、
バンキング３ａｉたは○リング３ｂを介して上蓋２を締

信頼性のある十分な防水効果を得ることができなかった
。However, in electronic devices with such a structure,
The waterproofing effect varies greatly depending on the strength when tightening the top cover 2 via the banking 3ai or the ○ ring 3b.
It was not possible to obtain a reliable and sufficient waterproofing effect.
本発明は上記従来の欠点を除去するためになされたもの
であり、バッキングの外周部を本体の開口端縁に設けら

するものである。The present invention has been made to eliminate the above-mentioned conventional drawbacks, and includes inserting the outer peripheral part of the backing into a groove provided at the opening edge of the main body, and forming annular protrusions on both sides of the banking. The purpose is to provide electronic equipment with a waterproof function.
以下図面を用いて本発明の詳細な説明する。The present invention will be described in detail below using the drawings.
第３図は本発明の一実施例における防水機能を有する電
子機器の要部拡大断面図を示している。FIG. 3 shows an enlarged sectional view of a main part of an electronic device having a waterproof function according to an embodiment of the present invention.

ている。In the figure, the outer circumference 16 of the backing 13 is inserted into the groove 15 provided in the case body 11, and the backing 13 is inserted into the groove 15 provided in the case body 11.
On both sides of 3, an annular convex portion 17 having a small diameter and a large diameter is formed along the annular backing. Note that the upper cover 12 is fastened to the case body 11 with screws 14.

り完全な防水効果が得られる。According to the electronic device having such a structure, the end portion 1 of the backing 13
6 is inserted into the groove 16, the position of the backing 13 is accurately defined and does not shift, and water can be completely prevented from flowing in from the lower surface of the backing 13. Furthermore, an annular convex portion 17 is provided on both sides of the backing 130.
is formed, so the backing 13 and case body 11 are smaller than the flat backing! ! , bamboo backing 1
3 and the upper lid 12 becomes smaller, the pressing force on the contact surface becomes larger, the airtightness becomes extremely high, and a complete waterproof effect is obtained.

業上の利用価値が高い。As explained below, in the electronic device having the waterproof function of the present invention, the backing does not shift due to changes in the tightening of the screws, and the inside of the case body is completely airtight regardless of the tightening strength. It can be maintained and has high industrial utility value.
