Rotary electrical contact assembly with improved contact collector retaining means

Claim 2

A rotary electrical contact and brush assembly of the character defined in claim 1, further characterized in that said core member and said housing are provided with a plurality of radially aligned, spaced annular recesses in the outer surfaces thereof, each such recess having an electrical conductor wound in at least a segment thereof, and each said conductor is formed as a twisted pair to form a lead to the arcuate conducting element and the brush member associated therewith, respectively.

Claim 3

A rotary electrical contact and brush assembly comprising a cylindrical core member and a housing therefor disposed in concentric, rotatable relation, an annular recess in said core member, an electrical conductor wound on at least a segment of said core member within said recess to form an arcuate conducting element, an opening in said core member through which each end of said conductor is threaded into the interior of said core member, an annular recess in said housing, a pair of openings in said housing in said recess, a pair of brush members secured in said housing recess disposed so that one end of each said pair each projects through one of said pair of openings in said housing into sliding electrical contact with said arcuate conducting element, the ends of said electrical conductor and the opposite ends of each brush member being formed as a twisted pair to provide an electrical lead to said arcuate conducting element and said brush members, respectively.

Claim 4

A rotary electrical contact and brush assembly comprising a cylindrical core member and a housing therefor disposed in concentric, rotatable relation, an annular recess in said core member, an electrical conductor wound on at least a segment of said core member within said recess to form an arcuate conducting element, an opening in said core member through which each end of said conductor is threaded into the interior of said core member, an annular recess in said housing member, an opening in said housing in said recess, and a pair of brush members in said housing recess disposed so that one end of each said pair projects through said opening in said housing into sliding electrical contact with said arcuate conducting element on said core member, and a second electrical conductor disposed in said recess in said housing to retain said brush members therein.

Claim 5

A rotary electrical contact and brush assembly of the character defined in claim 1, further characterized in that said housing member has an area of increased inner diameter forming an annular space between said core and said housing member into which said brush member projects through said opening in said housing into sliding electrical contact with said electrical conductor.

Claim 6

A rotary electrical contact and brush assembly comprising a cylindrical core member and a housing therefor disposed in concentric, rotatable relation, an annular recess in said core member, a plurality of electrical conductors supported by spaced segments of said core member within said recess to form segmented arcuate conducting elements, an opening in said core member through which each end of each conductor is threaded into the interior of said core member, an annular recess in said housing, an opening in said housing in said recess, at least one brush member in said housing recess disposed so as to project through said opening in said housing into sliding electrical contact with said arcuate conducting element on said core member, and a second electrical conductor disposed in said recess in said housing in electrical contact and retaining relation with said brush member.

Claim 7

A rotary electrical contact and brush assembly of the character defined in claim 7 further characterized in that the ends of each conductor are formed as a twisted pair to provide an electrical lead to said arcuate conducting element and said brush member, respectively.
