Abstract

An electrical connecting device, which is immersible remote controlled and able to transmit also remote control or telemetry signals. A primary coil (15) connected to the primary circuit is arranged upon a support or rod (1) in order to be displaceable, together with the magnetic core component integral with it, relatively to the secondary coil (16) with its magnetic core portion, all this in such a fashion as to create inductive coupling for the transmission of alternating (three-phase) electrical power, and to enable said two parts to be arbitrarily interpenetrated and parted from one another, in a single operation and whatever the orientation.

Claims

1. In an electrical connecting device for transmitting electrical energy from a first part to a second part, said parts being displaceable relatively to one another, comprising, a primary coil connected to said first part, a secondary coil connected to said second part, said coils having same axis of symmetry, a magnetic circuit with an air gap, and said magnetic circuit consisting of magnetic plates, means for displacing one of said parts relatively to said another part whereby to inductively couple said coils which are integral with said parts respectively when said coils have been properly displaced, and said inductive coupling being achieved irrespective of the relative angle of said coils about said axis of symmetry, the improvement of having slots formed in said magnetic circuit for housing said primary and secondary coils respectively, said coils being electrically connected as the rotor and the stator of a polyphase asynchronos motor, and stop support for preventing relative rotation between said displaceable parts of said connecting device.

2. In an electrical connecting device according to claim 1, for transmitting electrical energy together with electrical signals from a first part to a second part, the provision of a second set of coils independant from the first set comprising a primary coil connected to said first part and a secondary coil connected to said second part, a magnetic circuit with an air gap, said coils of the second set being inductively coupled through said air gap, as said first and second parts are properly displaced to inductively couple said first set of coils, and both said sets of coils having their respective planes of turns substantially at right angle to one another.

3. An electrical connecting device according to claim 2, wherein said first set of coils for transmitting electrical energy produces a radial rotating field perpendicular to said axis of symmetry of said coils, whereas said second set of coils for transmitting electrical signals produces a fixed field and operates in a single-phase manner.

4. An electrical connecting device according to claim 2, wherein said means for displacing one of said parts relatively to the other is lifting means for enabling one of said parts as a mobile part to slide into said another part as a fixed part along said axis of symmetry, whereby to establish the inductive coupling of both said sets of coils respectively when said moving part is set in said fixed part, and to disconnect said coupling when said moving part is lifted outside said fixed part.

5. An electrical connecting device according to claim 4 wherein said moving part which penetrates into said fixed part is given a tapered outline and said fixed part is given a corresponding outline to fit said tapered outline.

6. An electrical connecting device according to claim 5, wherein further said fixed part is provided with external guide means for facilitating the sliding in of said moving part into said fixed part.

7. In an electrical connecting device according to claim 2, designed to operate in a corosive medium wherein said magnetic circuits comprise an air gap and said air gap may possibly contain said corrosive medium, the provision of a protective coating for protecting the plates of said Magnetic circuits against corrosion by said corrosive medium.

8. An electrical connecting device for transmitting electrical energy and electrical signals, said device operating in a corrosive medium such as seawater, comprising a first part and a second part which are displaceable relative to each other along a common axis of symmetry, a first and a second primary coils connected to said first part and said coils being independant from each other, a first and a second secondary coils connected to said second part and said coils being independant from each other, a first magnetic circuit with an air gap and a second magnetic circuit with an air gap, said magnetic circuits being respectively associated with said first and second primary and secondary coils respectively, means for displacing said first and second parts with their integral coils and magnetic circuits, relatively to one another, and said first primary and secondary coils, as a first set of coils, so as said second primary and secondary coils as a second set of coils, being inductively coupled through said air gaps respectively of said magnetic circuits, when said one part is displaced along said axis of symmetry into said other part, the coils of one set being arranged so as to produce a radial rotating field perpendicular to said axis whereby, to transmit said electrical energy, the coils of the other set being arranged so as to produce a fixed field whereby to transmit said electrical signals, stop support for preventing relative rotation between said displaceable parts and protective coating in said air gaps for protecting said magnetic circuits against corrosion by seawater.
