Abstract:
An electrode of a vacuum circuit breaker comprising:a cup member having an opening and a periphery which is formed with a slit so as to form a coil section, an electric current flowing in the coil section so as to generate a longitudinal magnetic field in a direction along an axis of the cup member, the slit being bent and continuously extending on the periphery from a first end of the cup member to a second end of the cup member opposite to the first end of the cup member; and a contact shaped into a plate, and sealing the opening of the member whereinthe bent slit comprises of: a first line segment having a first end which is substantially perpendicular to a reverse face of the contact, the reverse face sealing the opening of the cup member, and a second line segment continuously connected to a second end of the first line segment opposite to the first end of the first line segment, the first line segment and the second line segment forming an inclination greater than a right angle, the second line segment being substantially parallel to the reverse face of the contact.
