Title: Tap selector
Inventor: NAKANO MASANORI
IPC: H01F29/02
Filed: 1990-03-22
Abstract: PURPOSE:To prevent mechanical damage by avoiding the frictional force and impact force to be added to the fixed contact at the time of closing or opening of a movable contact point, to suppress the generation of metal powder, and to improve reliability by a method wherein the surfaces of a casting insulator and the fixed contact point of plural pieces are brought into the same plane. CONSTITUTION:The two rod-like contacts 6, provided on a movable contact point 5, are moved to the specified contact position of a fixed contact point 1b while a current collecting ring 4 is performing a rolling movement on an insulator 2 in an always pressed state by each compression spring in the direction where a ring-shaped casting insulator 2 and a current- collecting ring 4 are pinched. When the above-mentioned contacts 6 come in the region of the contact point 1b from the region of the insulator 2, namely, when it is introduced, or when it comes out to the region of the insulator 2 from the region of the contact point 1b when an arbitrary fixed contact point is selected from the contact point 1b, namely, when contact is parted, as the contact point 1b and the insulator 2 are formed in the same thickness and have the same plane surface, the rod-like contacts 6 are shifted by simply performing a rolling movement on the same plane surface. Accordingly, the friction force and the impact force at the time of closing or opening the of the contact point 5 are not added to each fixed contact point, there is no possibility of occurrence of mechanical damage, the generation of metal powder is suppressed, and reliability can be improved.
