Abstract

케이스와 커버의 접촉위치를 일정하게 하여 시일드효과가 높은 시일드케이스를 제공한다.The contact position between the case and the cover is made constant to provide a shield case with a high shielding effect.

측벽의 적어도 대향하는 2면에 개구(2)를 설치한 금속제의 본체(1)에 대하여 그 개방면을 덮도록 금속제의 상커버(3) 및 하커버(4)가 설치되고, 이들 커버에는 개구(2)에 끼워맞추는 절곡부(7,8)가 형성된 탄성접촉편(5,6)을 구비한 시일드케이스에 있어서, 탄성접촉편(5,6)의 선단부가 개구(2)를 넘지않는 길이로 한다. 이로써 탄성접촉편(5,6)의 선단에 설치된 절곡부(7,8)는 항상 후단부근의 경사면만이 개구(2)의 한쪽내연에 접촉하고, 접촉상태가 안정하게 되어 충분한 시일드성을 확보할 수 있다.A metallic upper cover 3 and a lower cover 4 are provided so as to cover the open surface of the metallic body 1 having the opening 2 provided on at least two opposite sides of the side wall, and the openings are provided in these covers. In the shield case provided with the elastic contact pieces 5 and 6 with the bent parts 7 and 8 fitted to (2), the tip of the elastic contact pieces 5 and 6 does not exceed the opening 2. Length. As a result, in the bent portions 7 and 8 provided at the ends of the elastic contact pieces 5 and 6, only the inclined surface near the rear end always contacts one inner edge of the opening 2, and the contact state is stabilized, thereby ensuring sufficient shielding properties. can do.
