ASSEMBLY HAVING ELECTRICAL INTERCONNECTION MEMBER BETWEEN TWO MEMBERS WHICH CAN RELATIVELY ROTATE INDIVIDVALLY

摘要

PURPOSE: To reduce effects on signals exerted by both of the cross-linking between mutual connections and locally generated magnetic field by making an assembly in which two members relatively revolvable around a shaft are provided and an electric mutual connection material extends between the two members. CONSTITUTION: An one member 10 of two members 10 and 12 relatively revolvable around a shaft 13 is provided with a radially internal part 14 and a radially external part 15. Each component is formed into a hollow cylinder shape having a vertical shaft which is coaxial with the shaft 13 of the assembly and the two parts are joined at one end 16. The member 10 forming an annulus ring is mounted so as to revolve together with an arbor. The arbor is coaxial with the shaft 13, extends in the hollow cylindrical internal part 14 and is fixed to the internal part 14. Thus, a necessary electric shielding is imparted between the electric mutual connection material of the two selected groups of the assembly although the shielding has a comparatively easy constitution and effects on signals exerted by both of the cross-linking between the mutual connection material and locally generated magnetic field can be reduced.
