When the plug 164 is inserted into the insertion hole 165a of the cover 165 so that the protrusion 166a formed in the mounting groove 166b is coupled to the fixing part 163a of the connection terminal 163, The plug 164 is elastically supported and connected, and external power supplied through the plug 164 is connected to the connection terminal 163, the connection pin 162 connected to the connection terminal 163, and the connection pin ( It is supplied to the stator 21 through a wire 21a connected to 162 to generate a rotational force by the interaction of the stator 21 and the rotor 22.
이와 같이 본 발명에 의한 압축기의 전원 공급장치는 절연체로 형성된 커버(165)의 내부에 상기 플러그(164)가 삽입되었을 시, 상기 플러그(164)와 전기적으로 연결되는 상기 접속단자(163)가 형성됨으로써, 상기 커버(165)가 외부의 힘으로부터 상기 접속단자(163)의 손상을 방지하게 되는 것이다.As described above, when the plug 164 is inserted into the cover 165 formed of an insulator, the power supply of the compressor according to the present invention forms the connection terminal 163 electrically connected to the plug 164. As a result, the cover 165 prevents damage to the connection terminal 163 from external force.
이상에서 살펴본 바와 같이 본 발명에 의한 압축기의 전원 공급장치는 외부전원에 연결된 플러그가 삽입되었을 시에 접속단자가 상기 플러그와 전기적으로 연결되도록 상기 접속단자를 커버의 내부에 형성함으로써, 보관 시에나 제조과정 및 사용중에 외력에 의해 손상되어 생산성 및 제품의 신뢰성이 저하되는 것을 방지하는 효과가 있다.As described above, the power supply device of the compressor according to the present invention forms the connection terminal inside the cover such that the connection terminal is electrically connected to the plug when the plug connected to the external power source is inserted, and during the storage or manufacturing process. And it is effective to prevent the damage caused by external force during use to lower the productivity and reliability of the product.
또한, 플러그와 접촉되는 상기 커버에 상기 플러그의 삽입방향을 제한하는 오결선 방지부가 형성되어 오결선에 의한 전동기구부의 역회전 등에 의한 압축기의 손상을 방지하는 효과가 있다.In addition, there is an erroneous wiring preventing portion for limiting the insertion direction of the plug to the cover in contact with the plug has the effect of preventing damage to the compressor due to the reverse rotation of the power mechanism by the erroneous wiring.
