には炭化物が付着するおそれがある。この炭化物は良導
体であるので、炭化物が密封端子の絶縁部に付着すると
絶縁性が悪（なるという可能性がある。In the above conventional technology, if the overload relay fails, the locking current flows continuously through the electric element, which may cause the electric element to generate heat. etc. may carbonize and adhere to the inside of the casing. Since this carbide is a good conductor, if the carbide adheres to the insulating part of the sealed terminal, there is a possibility that the insulation will deteriorate.
本発明の目的は、密封端子の絶縁性を向上させた密閉形
電動圧縮機を堤供することにある。An object of the present invention is to provide a hermetically sealed electric compressor with improved insulation of hermetically sealed terminals.
上記目的は、圧縮要素、電動要素をケーシング内部に有

できる。したがって、電動要素が発熱した場合であって
も発生する炭化物が前記ガラスシールの表面に付着する
ようなことがなくなり、これにより絶縁不良が防止でき
る。By fitting the cylindrical portion of the cluster to the inner wall of the cup-shaped sealed terminal, the cylindrical portion of the cluster can cover the glass seal. Therefore, even if the electric element generates heat, generated carbides will not adhere to the surface of the glass seal, thereby preventing insulation defects.
以下、本発明の一実施例を第１図により説明する。第１
図は本発明の密閉形電動圧縮機の要部断面図である。An embodiment of the present invention will be described below with reference to FIG. 1st
The figure is a sectional view of essential parts of the hermetic electric compressor of the present invention.

密封端子３のピン７に挿入固定されている。クラスタ１
０には円筒部１０ａが設けられており、この円筒部１０
ａの外径が密封端子３のボディ６の円筒部内に嵌合して
、密封端子３の内側をカバーするようになっている。In FIG. 1, the lead wire 9 of the stator 5 is connected to the cluster 10.
, and are inserted and fixed into pins 7 of a sealed terminal 3 fixed to the side wall of the casing 1. cluster 1
0 is provided with a cylindrical portion 10a, and this cylindrical portion 10
The outer diameter of a is fitted into the cylindrical portion of the body 6 of the sealed terminal 3 to cover the inside of the sealed terminal 3.
まな、クラスタ１０及び円筒部１０ａの材質としては、
たとえばケイ砂と粘土を主成分としたセラミックス等で
一体に成形した構造にしである。The materials of the cluster 10 and the cylindrical portion 10a are as follows:
For example, it has a structure made of ceramics whose main ingredients are silica sand and clay.
尚、クラスタ１０の円筒部１０ａを密封端子３のボディ
６の円筒部内に圧入しても良い。Note that the cylindrical portion 10a of the cluster 10 may be press-fitted into the cylindrical portion of the body 6 of the sealed terminal 3.
本実施例によれば、何らかの原因で電動要素が焼損し炭
化物が発生しても、クラスタ１０の円筒部１０ａで密封
端子３の内側がカバーされているため、前記炭化物が密
封端子３の内側のガラスシール８に付着することが防止
でさる効果がある。According to this embodiment, even if the electric element is burnt out for some reason and carbide is generated, the inside of the sealed terminal 3 is covered by the cylindrical portion 10a of the cluster 10, so that the carbide is removed from the inside of the sealed terminal 3. This has the effect of preventing adhesion to the glass seal 8.
また、クラスタをセラミックス等で形成することにより
熱によってクラスタが劣化することはないので、更に絶
縁性の向上を図ることができる。Further, by forming the clusters from ceramics or the like, the clusters will not be deteriorated by heat, so that the insulation properties can be further improved.
本発明によれば、密封端子の内側に、事故により発生し
た炭化物が侵入し絶縁不良となることを防止出来る。According to the present invention, it is possible to prevent carbide generated due to an accident from entering the inside of a sealed terminal and causing insulation failure.
