그러나 이러한 종래의 밀폐형 회전식 압축기의 터미널커버 결합구조는 별도의 부속부품이 요구될 뿐만 아니라 그 부속부품을 설치하기 위한 작업이 추가됨으로써 원가상승은 물론 작업공수가 증가되고, 또한 작업이 번거롭고 불편하여 작업의 비효율성 및 생산성 저하를 초래하는 문제점이 있었다. 따라서 본 발명의 목적은 터미널커버를 별도의 부속부품없이 보다 간편하면서 효율적으로 밀폐용기에 결합시킬 수 있도록 하는데 있다.However, the terminal cover coupling structure of the conventional hermetic rotary compressor not only requires separate accessory parts, but also adds work for installing the accessory parts, thereby increasing the cost of labor as well as the labor time, and also making the work cumbersome and inconvenient. There was a problem that leads to inefficiency and reduced productivity. Therefore, an object of the present invention is to enable the terminal cover to be coupled to the sealed container more simply and efficiently without a separate accessory.

The protrusion 112A is formed in the same shape inclined to one side. In the assembly of the present invention having such a structure, first, the terminal cover 112 to the hermetic terminal (112A) of the fixing projection (112A) of the terminal cover 112 in the inlet side of the fixing groove 111 of the top cap (1A) ( 14) on the upper side. Then, by pressing the terminal cover 112, the fixing protrusion 112A of the terminal cover 112 is forcibly pressed into the fixing groove 111 of the top cap 1A, thereby completing a series of assembling. The fixing groove 111 of the top cap 1A and the fixing protrusion 112A of the terminal cover 112 forcedly pressed into the wedge are inclined to one side so that they are firmly and stably combined without being separated from each other.

이같이 본 발명은 터미널커버를 강제 압입식으로 밀페용기의 탑캡에 결합시킬 수 있도록 함으로써 별도의 부속부품이 불필요할 뿐만 아니라 작업이 간편해 원가절감은 물론 작업의 효율성 및 생산성을 한층 증대시킬 수 있는 효과를 갖게 된다.As such, the present invention enables the terminal cover to be coupled to the top cap of the airtight container by a forced press-type, so that separate parts are not necessary and the operation is simple, thereby reducing the cost and increasing the efficiency and productivity of the work.
