Abstract:
A high frequency relay comprising:a dielectric base mounting three fixed contacts defining a common (COM) contact, a normally-closed (NC) contact, and a normally-open (NO) contact, respectively, said NC and NO contacts being arranged on opposite of said COM contact, each of said fixed contacts being defined at a tip of each corresponding one of three contact terminals extending through said base;a first movable contact spring bridging said COM contact and said NC contact for closing and opening a first high frequency signal path defined therebetween;a second movable contact spring bridging said COM contact and said NO contact for closing and opening a second high frequency signal path defined therebetween;a driving mechanism causing said first and second movable contact springs to move for closing and opening said first and second high frequency signal paths alternately;a pair of electromagnetic shield plates upstanding from said base to define a shielded space between said shield plates for accommodating therein said three fixed contacts, said first movable contact spring, and said second movable contact spring,each of said shield plates being configured to come into electrical contact with corresponding one of said first and second movable contact springs moved in a contact opening position;whereineach of said shield plates being integrally formed with at least one ground terminal which extends continuously from a bottom of said shield plate through said base, andeach of said shied plates being configured to cover said first and second movable contact springs over the full length thereof without any interruption for completely shielding said first and second high frequency signal paths.
