Title:
ELECTRIC-DISCHARGE MACHINING SWITCHING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2013/154149
Kind Code:
A1
Abstract:
A switching apparatus, the purpose of which is to provide an electric-discharge machining switching apparatus that can keep down problems such as poor connections arising as a result of wear of parts due to reciprocating motion of moving parts or the like, is equipped with a housing, a first conductor (13), a second conductor (14), a third conductor (15), and a driving means (17). The housing forms tightly-sealed space, and the third conductor can move back and forth within the housing. The first conductor comprises a connection face (13A) that is parallel to the movement direction of the third conductor. The second conductor comprises a connection face (14A) that forms, with the connection face of the first conductor, a wedge-shaped space the size of which becomes smaller in the forward direction. The third conductor comes in contact, by moving forward, with both the connection face of the first conductor and the connection face of the second conductor within the wedge-shaped space, and electrically connects the first conductor and the second conductor.
