〔産業上の利用分野〕
本発明は電磁継電器等の電気機器の密封方法１ζ関する
。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method 1ζ for sealing electrical equipment such as electromagnetic relays.
本発明は、樹脂材からなるケーシングに形成したエアー
抜き孔の外面部をガス抜きの後溶融着させる電気機器の
密封方法において、前記エアー抜き孔の内面部の一部を
内部の固定部品に当接せしめ、加熱具をこの当接部に向

してエアー抜き孔を溶融着するようにしたものである。The present invention provides a sealing method for electrical equipment in which the outer surface of an air vent hole formed in a casing made of a resin material is melt-bonded after degassing, in which a part of the inner surface of the air vent hole is attached to an internal fixed part. By pressing the heating tool toward the abutting portion, pinholes are eliminated and the air vent hole is melted and bonded.

では、速乾性の通弊として接着強質が弱く信頼性に欠け
るとともに、常時流していないと接着剤が固ってしまう
ために自動機による作業に向かず、人手によっており、
作業能率が悪いといった問題点を有している。Conventionally, as a method for sealing an air vent hole formed in a casing after degassing, there is a method of first filling the air vent hole with a quick-drying adhesive. However, the disadvantage of this method is that the adhesive strength is weak and unreliable, and the adhesive hardens if it is not constantly flowing, making it unsuitable for automatic machines and requiring manual work.
It has problems such as poor work efficiency.
また、前記エアー抜き孔の外面部を熱により溶かして封
着させるといった方法が提供されている。Furthermore, a method has been proposed in which the outer surface of the air vent hole is melted and sealed by heat.
これでは自動機によって作業能率の向上を図ることがで
きる反面、どうしてもピンホールが多数発生して密封が
不完全になるといった問題点を有している。その原因は

抜き孔を形成した部分は浮き上がっているので、溶融着
部分に十分な圧力を加えられないためであると考えられ
る。Although this method can improve work efficiency using automatic machines, it has the problem that many pinholes inevitably occur, resulting in incomplete sealing. The reason for this is that in the fusion bonding method, the periphery of the air vent hole is melted, and it gathers around the air vent hole and hardens, but the part of the casing where the air vent hole was formed is raised. This is thought to be due to not being able to apply sufficient pressure to the fused portion.
そこで、本発明に係る電気機器の密封方法は、エアー抜

接しつつエアー抜き孔を溶融着することを特徴とする。Therefore, in the method for sealing an electrical device according to the present invention, a part of the inner surface of the air vent hole is brought into contact with an internal fixed part, and a heating tool is pressed against the outer surface of the air vent hole toward this contact part. The feature is that the air vent hole is fused and bonded while

A part of the inner surface of the air vent hole is in contact with the internal fixed part, so when the heating tool is brought into pressure contact with the outer surface of the air vent hole, sufficient pressure is applied to the welded part and the pinhole is closed. This will prevent the occurrence.

２を構成するヨーク３の上端面に当接している。[Example] Fig. 1 shows an electromagnetic relay just before being sealed. The relay main body 2 mounted on the base 1 is covered with a case 5, and the joint between the base 1 and the case 5 is formed by a well-known method. Sealed. The case 5 is made of thermoplastic resin, and a protrusion 6 having an air vent hole 7 is provided on the top surface 51 of the case 5 . The upper surface portion 5a has a thick wall from the air vent hole 7 to the right side in FIG.

溶融してエアー抜き一部を有しながら密封されていく。The sealing operation is performed by exhausting the organic gas inside through the air vent hole 7, and then pressing the heater 10 against the protrusion 6 from above, as shown in FIGS. 21 and 2b. That is, when the heater 10 touches the protrusion 6, the periphery of the air vent hole 7 is melted and sealed while having a portion of the air vent hole.

後、ヒータ１０を上方に引き上げる。At this time, when the heater IO is pressurized downward, the protrusion 6 is pressed against the heater 10 and the upper end surface of the yoke 3, and sufficient pressure is applied to eliminate the numerous pinholes and air vent holes. 7 will be completely sealed. After that, the heater 10 is pulled upward.

３に限定するものではない。In addition, in the present invention, the air vent hole 7 and the protrusion 6 can have various shapes other than those in the above embodiment, and the part that the inner surface of the air vent hole 7 comes into contact with is limited to the yoke 3. It's not something you do.

Therefore, not only is it possible to automate the sealing work, but also sufficient pressure can be applied to the welded part of the air vent hole, preventing pinholes from forming and achieving complete sealing.
