Claims

[Scope of Claim for Utility Model Registration] (1) A pair of electrodes that can be freely connected and separated are arranged inside a vacuum container in which both openings of an insulating cylinder are closed with end plates, and this electrode is vertically connected to the main electrode. In a vacuum valve that is composed of a coil electrode that generates a magnetic field and is provided with a reinforcing member that increases the mechanical strength of the coil electrode, the reinforcing member is in the shape of a disk, and a first part protruding in one direction is provided at the center of the vacuum valve. A vacuum valve characterized in that a second protrusion is provided between the center and the outer periphery, the second protrusion protruding in the other direction and engaging with the arm of the coil electrode. (2) The vacuum valve according to claim (1), in which the second protrusion is L-shaped. (3) The vacuum valve according to claim (1) of the utility model registration, in which the second protruding portion is press-molded. (4) Utility model registration claim No.
Vacuum valve described in (1). (5) The vacuum valve according to claim (1) of the utility model registration, in which a second reinforcing member is laminated on the reinforcing member. (6) Utility model registration claim No. (5) in which the second reinforcing member is provided with a protrusion that prevents the reinforcing member from rotating.
Vacuum valve as described in section.
