Abstract

본 발명은 전자렌지의 마그네트론에서 발생되는 노이즈를 효과적으로 차폐시킬 수 있는 차폐장치에 관한 것으로서 종래에는 차폐장치에 소요되는 부품이 상당히 많은 부품으로 형성된 것이기 때문에 재료비의 증가는 물론 조립공정에 소요되는 시간이 상당하여 생산성이 저하되는 폐단이 있는 것이므로 본 발명은 실드케이스(100)와; 상기 실드케이스(100)의 일측면을 타발 형성하여 개구부(111)가 구비된 돌출부(110)와; 상기 돌출부(110)의 상면에 고정되며 몸체 상하면으로 분리전극(11)과 공통전극(12)이 부착되고 관통구멍(13)이 형성된 세라믹 유전에(10)와; 상기 관통구멍(13)에 끼워지며 상부에는 절곡편(32)이 구비된 관통도체(30)와;상기 세라믹 유전체910) 상,하부 및 관통구멍(13)사이에 몰딩 성형되는 절연수지(120)에 의하여 구성되는 것으로서 이와같은 본 발명은 커패시터를 구성하는 부품이 실드케이스(100)의 돌출부(110)에 접면되는 세라믹유전체(10)와 관통구멍(13)에 끼워지는 관통도체(30)에 의하여 구성되는 것인바, 종래에 비하여 부품의 수가 절반수준으로 감소되는 것이므로 전체적인 제작비의 절감과 함께 조립공정을 간소화 시킬 수 있는 것이다.The present invention relates to a shielding device capable of effectively shielding the noise generated from the magnetron of the microwave oven. Since the components required for the shielding device are formed of a large number of components, the time required for the assembly process is increased as well as the material cost. The present invention is a shield case 100 because there is a closed end is equivalent to a decrease in productivity; A protrusion 110 having one side surface of the shield case 100 provided with an opening 111; A ceramic dielectric 10 fixed to an upper surface of the protruding portion 110 and having a separation hole 11 and a common electrode 12 attached to the upper and lower surfaces of the body and having a through hole 13 formed therein; A through conductor 30 inserted into the through hole 13 and having a bent piece 32 thereon; and an insulating resin 120 molded between upper and lower portions of the ceramic dielectric 910 and the through hole 13. The present invention is constituted by the through-conductor 30, the component constituting the capacitor is fitted in the ceramic dielectric 10 and the through hole 13 which is in contact with the protrusion 110 of the shield case 100. Since the number of parts is reduced by half compared to the prior art, it is possible to simplify the assembly process with the reduction of the overall manufacturing cost.
