従来のリレー、スイッチその他の小型電気器具の密封ケ
ースは、第１図の如く、合成樹脂よりなる上端開口の箱
体ａの側壁に端子ｂを同時成型に貫通固定し、箱体ａの
開口端にカバーｃの開口端を接着剤にて気密的に接合し
てなる。DETAILED DESCRIPTION OF THE INVENTION Conventional sealed cases for relays, switches, and other small electric appliances are made by simultaneously molding and fixing terminals b to the side walls of a box body a made of synthetic resin and having an open top, as shown in Figure 1. , the open end of the cover c is hermetically joined to the open end of the box body a using an adhesive.
ところが、端子ｂが貫通する側壁の貫通孔ｄの内周胴と
端子ｂの貫通する部分の外周胴間に箱体ａの熱膨張によ
り間隙が生じ、完全に気密的に密封することはできない
欠点があつた。本発明は上記のような従来の欠点を除去
するものであつて、以下本発明を実施例を第２図につい
て説明すると、１は合成樹脂よりなる開口部２を有する
箱体、３は箱体１の側壁に貫通固定せる複数個の端子、
４は箱体１の開口縁に形成せる溝で、前記各端子３の貫
通部分の一側面は溝４内に露出するようになされる。However, due to thermal expansion of the box body a, a gap is created between the inner circumferential shell of the through hole d in the side wall through which the terminal b passes and the outer circumferential shell of the portion through which the terminal b penetrates, and a complete airtight seal cannot be achieved. It was hot. The present invention is intended to eliminate the above-mentioned drawbacks of the conventional art, and an embodiment of the present invention will be explained below with reference to FIG. 2. 1 is a box having an opening 2 made of synthetic resin; a plurality of terminals that can be fixed through the side wall of 1;
Reference numeral 4 denotes a groove formed in the opening edge of the box body 1, and one side of the penetrating portion of each terminal 3 is exposed in the groove 4.
５は溝４内に充填せる接着剤、６はカバーで、その開口
端縁を前記溝４に嵌合してカバー６の開口端縁は箱体１
の開口端縁に接着剤にて気密的に接着されるものである
。5 is an adhesive to be filled into the groove 4; 6 is a cover whose opening edge is fitted into the groove 4; the opening edge of the cover 6 is connected to the box body 1;
It is hermetically bonded to the edge of the opening with an adhesive.
第３図は本発明の異なる実施例を示すもので、上下端に
開口部２、２を有する合成樹脂よりなる箱体１の側壁に
複数個の端子３を貫通固定し、両開口端縁に溝４、４を
設けて該溝４、４内に各端子３の貫通部分の全外周胴面
を路出し、溝４、４内に接着剤５を充填し、カバー６、
６の開口端縁を前記溝４、４に嵌合してカバー６、６の
開口端縁を箱体１の開口端縁に接着剤５にて気密的に接
着してなるものである。かように本発明は、溝４に充填
せる接着剤５がカバー６の開口端と箱体１の課口端とを
気密的に接着し、かつ接着剤が端子の外周胴と該端子が
貫通する部分の箱体間に接着し、完全に気密的に密封さ
れた密封ケースを提供できる効果がある。FIG. 3 shows a different embodiment of the present invention, in which a plurality of terminals 3 are fixed through the side wall of a box body 1 made of synthetic resin having openings 2, 2 at the upper and lower ends, and at the edges of both openings. Grooves 4, 4 are provided, the entire outer circumferential body surface of the penetrating portion of each terminal 3 is exposed in the grooves 4, 4, adhesive 5 is filled in the grooves 4, 4, and a cover 6,
The opening edges of the covers 6, 6 are fitted into the grooves 4, 4, and the opening edges of the covers 6, 6 are hermetically bonded to the opening edges of the box body 1 with an adhesive 5. Thus, in the present invention, the adhesive 5 filled in the groove 4 airtightly adheres the open end of the cover 6 and the section end of the box 1, and the adhesive 5 fills the outer circumferential body of the terminal and the terminal. This has the effect of providing a completely airtight sealed case by adhering between the parts of the box body.
