发明名称 HIGH FREQUENCY SIGNAL SWITCHING CIRCUIT
摘要 PURPOSE:To enable aquisition of isolation without soldering a shield case by modifying a shield case body and an upper cover for covering the shield base body. CONSTITUTION:A cover 3 for covering a shield case 4 is provided with projections 5, 6 which are bent through cuttings so that the end portions thereof collide, when these are assembled, with a part between the one input terminal of the shield plate and a partitioning plate and a desirable part of the patitioning plate. Otherwise, a shield plate 19 is provided extrudingly to cover an input port by 1/3 or more from the upper part of the shield plate of the one input port 2. Shielding can be ensured to prevent radiation to the adjacent port 1 and isolation can be realized without soldering the shield case 4 by colliding the projections 5, 6 of the cover 3 with the shield case body 4 and protruding the shield plate 19 to cover the input port 2.
