Abstract
A cable swivel for inductive power couplings for powering pool or spa components is provided. A swivel component allows a power cable to a pool or spa component, such as an electric pool cleaner, to swivel when the inductive power couplings are coupled together. The couplings include a first inductive coupling that can be positioned within and/or mounted into a wall fitting, a second inductive coupling that inductively couples with the first inductive coupling, and a swivel component attached to the second inductive coupling for allowing the second coupling to swivel with respect to the first inductive coupling. A retainer ring engages with the wall fitting and retains the first and second couplings and the swivel component in position within the wall fitting.
Claims10
In an inductive power coupling for powering a pool or spa component, the inductive power coupling having a first inductive coupling connected to a first power cable and a second inductive coupling connected to a second power cable and inductively coupled to the first inductive coupling, the first inductive coupling inductively transferring electricity to the second inductive coupling, the improvement comprising:
- a swivel component allowing said second inductive coupling and said second power cable to swivel with respect to said first inductive coupling, wherein the swivel component includes:
- (i) an inner component having an inner surface and an outer surface, the inner surface of the inner component attached concentrically about a cylindrical outer surface of a housing of the second inductive coupling, and (ii) an outer component having an inner surface and an outer surface, the outer surface of the outer component attached to an inner surface of a wall fitting, the outer component of the swivel component positioned concentrically about the inner component of the swivel component and the inner component of the swivel component positioned concentrically about the second inductive coupling, the outer component of the swivel component rotating with respect to the inner component of the swivel component to permit the second inductive coupling to swivel with respect to the first inductive coupling.
