  • Inductive coupler systems
    Patent number: 4586767
    Abstract: An inductive coupler system suitable for subsea use. The coupler has two sub-assemblies (17, 65) each including a magnetic half-core (35a, b). A tubular guide arrangement (18) is provided into which the first sub-assembly (17) is able to slide. The guide arrangement (18) includes means (63a, 63b) capable of co-acting with means (25a, 25b) fixed to the first coupler sub-assembly (17) so as to constrain the first coupler sub-assembly to take up a position within the guide arrangement to receive the second coupler sub-assembly (65) via an aperture (59) in the wall of the guide arrangement.
