Inductive coupler for power line communications
There is provided an inductive coupler for coupling a signal to a conductor. The inductive coupler includes (a) a magnetic core having an aperture through which the conductor is routed, (b) a winding wound around a portion of the magnetic core, where the signal is coupled between the winding and the conductor via the magnetic core, and (c) an electrically insulating, compressible material situated between the winding and the magnetic core, having a hardness of between about 10 and about 100 on a hardness type shore A durometer scale.
1. An inductive coupler for coupling a signal to a conductor, comprising:
a magnetic core having an aperture through which said conductor is routed;
a winding wound around a portion of said magnetic core, wherein said signal is coupled between said winding and said conductor via said magnetic core; and
an electrically insulating compressible material situated between said winding and said magnetic core, having a hardness of between about 10 and about 100 on a hardness type shore A durometer scale.
2. The inductive coupler of claim 1 , further comprising an electrically insulating material on an outward surface of said magnetic core, having a hardness of between about 10 and about 100 on a hardness type shore A durometer scale.
