Electrical-energy transfer device comprising a centering system

An electrical-energy transfer device comprising:

• a first part which comprises a first frontal face and at least one first electrical-energy transfer element, and
• a second part which comprises at least one second electrical-energy transfer element,
• the first and second parts being configured to move one relative to the other in a direction of closing between a distanced state and a close-up state,
• the first and second electrical-energy transfer elements being configured to perform a transfer of electrical energy between one another in the close-up state,
• the first part further comprising a first housing opening onto the first frontal face of the first part and comprising at least a first lateral surface, said first housing being configured to at least partially house the second part,
• the second part further comprising a second lateral surface for each first lateral surface of the first housing of the first part, the second part having an overall shape that complements the shape of the first housing,
• each first electrical-energy transfer element being positioned at the first lateral surface and each second electrical-energy transfer element being positioned at the second lateral surface and approximately centered with respect to one of the first electrical-energy transfer elements when the first and second parts are in the close-up state,
• the first part further comprising at least one layer of ferromagnetic elements surrounding the first lateral surface,
• each first electrical-energy transfer element being positioned between the layer of ferromagnetic elements and the first lateral surface.
