ABSTRACT:
Electrical connection apparatus for two conductors respectively connected to an electrical supply source and to a utilization device, the conductors being respectively secured to first and second elements which are relatively rotatable with respect to one another through the intermediary of a roller bearing having a cage constituted by first and second parts respectively secured to the first and second elements and balls inserted in the cage. First and second conductive contacts are fixedly secured to the first element and are in rubbing contact respectively with a first annular grounding track and a second annular conductive track. The first and second tracks are fixedly secured to the second part of the cage, the grounding track being formed by a thin layer of low electrical resistance deposited in a peripheral groove in the second part of the cage.
