Since it is mixed with the oil and refrigerant inside the sealed casing 7, it is carried by the refrigerant and adheres to various parts inside the sealed casing T.
The insulating plate 11 prevents it from adhering to the glass surface,
In addition, the gap 12 can weaken the attraction effect caused by static electricity at the end of the cylindrical portion 3.

ものである。Means for Solving the Problems In order to solve the above problems, the hermetic compressor of the present invention includes a metal outer ring having a through hole, a cylindrical part surrounding the through hole, and a metal outer ring. The terminal pin is hermetically and insulatively sealed in the through hole through glass, and the rubber covering this glass part is provided, and the outer peripheral surface of the cylindrical part or the metal outer ring is provided inside the sealed casing of the metal outer ring. The rubber is sealed and fixed to the inner circumferential surface of the pin and the outer circumferential surface of the pin.

全に密封するので金属粉は、ガラス表面に付着すること
がなくスパークによるガラスの破損が起こらず、絶縁距
離も延び、静電気によって金属粉が付着し難くなる。Effects of the present invention, as described above, allows the glass surface to be sealed and covered with the insulating rubber, so that the rubber completely seals the glass, preventing metal powder from adhering to the glass surface and causing sparks. The insulation distance is extended, and metal powder is less likely to adhere to the glass due to static electricity.
実施例
以下本発明の一実施例の密閉型圧縮機について、図面を
参照しながら説明する。尚、従来例と同一部品は同一符
号を用いて説明し、構成、動作の同じところは省略する
。第一図において、８はゴムの絶縁板で、端子ピン５の
外周９と金属外環４−体に固着されている。EXAMPLE Hereinafter, a hermetic compressor according to an example of the present invention will be described with reference to the drawings. Note that parts that are the same as those in the conventional example will be described using the same reference numerals, and parts that are the same in structure and operation will be omitted. In FIG. 1, reference numeral 8 denotes a rubber insulating plate, which is fixed to the outer periphery 9 of the terminal pin 5 and the metal outer ring 4.
以上のような構成において、端子ピン５と金属外環４と
の間の距離が離れるためにその間に金属粉等の付着物が
あってもスパークを起こすことはほとんど無く、ゴムの
絶縁板８が端子ピン６と金属外環４に一体に固着されて
いるのでガラス６表面に金属粉カＳ付着することは絶対
に無いためスパークによるガラス６の破損は起こらない
。In the above configuration, since the distance between the terminal pin 5 and the metal outer ring 4 is large, sparks are hardly caused even if there is a deposit such as metal powder between them, and the rubber insulating plate 8 Since the terminal pin 6 and the metal outer ring 4 are integrally fixed, there is absolutely no chance of metal powder S adhering to the surface of the glass 6, so the glass 6 will not be damaged by sparks.
従って、端子ピン６と金属外環４にゴムの絶縁板８が固

は無いので端子の破損を完全に防ぎ、ゴムの絶縁板８に
より、電気的な吸収力を弱め付着することを防ぐことも
可能で、スパークを起こさせず、漏電も無くすことがで
きる。Therefore, since the rubber insulating plate 8 is fixed to the terminal pin 6 and the metal outer ring 4, there is no metal powder attached to the glass surface, completely preventing damage to the terminal. It is also possible to prevent adhesion by weakening the electrical absorption power, preventing sparks and eliminating electrical leakage.

The insulation distance is extended, there is no attraction of metal due to static electricity, and
Since metal powder does not adhere directly to the glass surface, electrical leakage caused by sparks and damage to terminals can be eliminated.
