Patent ID: 8899991

Claim:
A rotatable electrical coupling comprising: a first connector having at least one electrical contact member for conducting or transmitting a supply current or a low-frequency control signal, and a further electrical contact member for conducting or transmitting a high-frequency and/or a high-speed data signal; and a second connector to be coupled with the first connector such that the first and second connectors are adapted for rotation relative to one another, wherein the second connector includes complementary electrical contact members engageable with the contact members of the first connector such that they maintain uninterrupted electrical contact members with each of the respective contact members of the first connector throughout a relative rotational movement between the first and second connectors, preferably through an angle of at least about 180°,wherein the first connector is a male connector and the second connector is a female connector adapted to releasably receive the male connector, wherein the female connector member comprises at least one complementary electrical contact member arranged inside the cavity or socket and arranged around or extending circumferentially of the cavity or socket.
