(イ) 考案の分野
本考案は、電磁継電器等電気機器の密封構造に
関するものである。[Detailed description of the invention] (a) Field of the invention The present invention relates to a sealed structure for electrical equipment such as electromagnetic relays.
(ロ) 従来技術とその問題点
前記電気機器の密封構造としては、種々の方式

することがあるという欠点を有する。 For example, in the conventional example shown in FIG.
A sealing material 5 made of, for example, liquid synthetic resin is filled between the circuit board 3 of the electrical device 1 and the inner wall 4 of the case opening. However, this method has the disadvantage that a large amount of sealing material 5 is required. Further, as shown in FIG. 2, a step 7 is provided at the edge of the board 3, and a terminal piece 6 is made to protrude from this step 7, and is formed by this step 7 and the inner wall 4 of the case 2. There is a method in which the sealing material 5 is injected into the annular groove 8. In this method, the sealant 5 can be used in a smaller amount than the former method, but the injection point for the sealant 5 is narrow and the injection work is troublesome, and the sealant 5 is also applied to unnecessary parts of the terminal piece 6. It has the disadvantage that it can stick.

ができるという効果がある。(d) Structure and Effects of the Invention In order to achieve the above object, the present invention forms an angled portion with an inclined surface in the center of the board, and flattens at least the edge of the angled portion where the terminal piece insertion portion is located. The periphery of the terminal piece and the peripheral edge of the board are sealed by injecting a sealing material into the recess formed between the inclined surface and the inner wall of the case opening. The injection work is extremely easy since it only needs to be above. Furthermore, the sealing material filling portion according to the present invention is a recess formed by the case inner wall and the inclined surface of the board, and the terminal piece insertion portion is a flat portion, as shown in FIG. 1 above. The effect is that the amount of sealing material used can be reduced to less than half compared to conventional products.
(ホ) 実施例の説明
つぎに、本考案を実施例である図面にしたがつ
て説明する。(E) Description of Examples Next, the present invention will be explained with reference to drawings which are examples.
第３図は本考案の第１実施例を示し、図におい
て、ケース２の開口部内側壁４には、図示しない
電磁継電器の基板３が装着されている。 FIG. 3 shows a first embodiment of the present invention, and in the figure, a substrate 3 of an electromagnetic relay (not shown) is mounted on the inner wall 4 of the opening of the case 2. As shown in FIG.
そして、前記基板３は、その表面中央部に４面
の傾斜面３１〜３４と、内側壁４と略同じ高さを
有する頂部３５とからなる山形部３６を有すると
ともに、基板３の周縁部は平担部３７となり、こ
の平担部３７に設けた挿通孔から電気機器の端子
片６が突出している。 The substrate 3 has a chevron-shaped portion 36 in the center of its surface, which is made up of four inclined surfaces 31 to 34 and a top portion 35 having approximately the same height as the inner wall 4, and the peripheral portion of the substrate 3 is It becomes a flat part 37, and the terminal piece 6 of the electric device protrudes from an insertion hole provided in this flat part 37.
したがつて、第４図に示すように、シール材５
をノズル９から山形部３６の頂部３５に注入する
と、シール材５は傾斜面３１〜３４を流下し、第
５図に示すように、ケース開口部内側壁４と傾斜
面３１〜３４および平担部３７で形成される凹所
１０にシール材５が充填され、ケース２と基板３
の縁部および端子片６の挿通部は完全に密封され
ることになる。この場合、基板３の山形部３６に
相当する部分のシール材５が不要であるため、そ
の不要の分だけシール材５を節約できる。 Therefore, as shown in FIG.
When injected from the nozzle 9 into the top 35 of the chevron 36, the sealing material 5 flows down the slopes 31 to 34, and as shown in FIG. The recess 10 formed by the portion 37 is filled with the sealing material 5, and the case 2 and the substrate 3 are
The edges and the insertion portion of the terminal piece 6 are completely sealed. In this case, since the sealing material 5 in the portion corresponding to the chevron portion 36 of the substrate 3 is not required, the sealing material 5 can be saved by the amount of unnecessary portion.
また、前記平担部３７を設けることなく、基板
３の全面に傾斜面を設けることも考えられるが、
このようにすると、端子片挿通部を傾斜面に設け
なければならず、端子片挿通作業が面倒であるば
かりか、端子片６のケース側は傾斜面となり、そ
れだけシール材が余分に必要となる。 Furthermore, it is also possible to provide an inclined surface on the entire surface of the substrate 3 without providing the flat portion 37;
In this case, the terminal piece insertion part must be provided on an inclined surface, which not only makes the terminal piece insertion work troublesome, but also the case side of the terminal piece 6 becomes an inclined surface, which requires extra sealing material. .
第６図、第７図および第８図は、本考案にかか

３８は端子片６の挿通孔を示す。 6, 7, and 8 show other embodiments of the present invention, and FIG. 6 shows the chevron portion 36.
7 has a hipped roof shape, FIG. 7 shows the entire chevron portion 36 in a flat semi-cylindrical shape with both ends cut out by slopes 31 and 33, and FIG. It has a curved surface. In addition,
38 indicates an insertion hole for the terminal piece 6.
以上の説明で明らかなように、本考案にかかる
電気機器の密封構造によれば、基板の表面に山形
部を形成するとともに、端子片挿通部を平担部と
したため、シール材の注入作業はケース開口の広
い範囲で行なえ、注入作業が容易である。 As is clear from the above explanation, according to the electrical device sealing structure according to the present invention, a chevron-shaped part is formed on the surface of the board, and the terminal piece insertion part is made into a flat part, so that the injection of sealing material is easy. The injection work can be performed easily over a wide range of the case opening.
しかも、基板には平担部と山形部とが形成して
あるので、シール材の使用量を減少できるととも
に、端子片は平担部に設けた挿通部に挿通するた
め、端子片の挿通作業も容易であるという効果を
奏する。 Moreover, since the board is formed with a flat part and a chevron-shaped part, the amount of sealing material used can be reduced, and since the terminal piece is inserted into the insertion part provided in the flat part, the insertion of the terminal piece is not easy. It also has the effect of being easy to use.
