Embodiment Construction

[0037] The invention will now be described in more detail with reference to the accompanying drawings.

[0038] figure 1A partially exploded view of the base of the contactless connector 100 inductively connectable to a corresponding mating connector is shown. The contactless connector 100 thus has a mating end 101 for interacting with a suitable mating connector (not shown in the figure, however), so that contactless power transfer and optionally additional signal transmission is possible. An inductive coupling element 110, in this example a coil with a plurality of windings 115, is arranged for inductively transferring energy to a corresponding mating connector. The first and second contact leads 103 , 104 supply and receive current to and from the winding 115 .

[0039] An outer ferrite element 107 is provided and arranged such that it at least partially surrounds the inductive coupling element. This creates an improved guidance for the B-field towards the mating connect...

Abstract

A contactless connector (100) for inductively connecting at a mating end (101) a corresponding mating connector comprises an inductive coupling element (110) for transmitting and / or receiving power to / from the corresponding mating connector and an outer ferrite element (107) around the inductive coupling element (110). The outer ferrite element (107) is magnetically coupled to a base plate (105) that comprises at least one lead-through (109) for accommodating at least one contact lead (103, 104) connected to said inductive coupling element (110). Only one lead-through (109) is provided for accommodating two contact leads (103, 104) connected to the inductive coupling element (110) in a way that the contact leads carry electric currents in opposing directions. Alternatively, the base plate (105) is formed to have at least one air gap (114, 116, 117) arranged in a magnetic path of a magnetic field induced by electric current flowing through said at least one lead.

Description

technical field [0001] The invention relates to a contactless connector for inductive connection to a corresponding mating connector, a contactless connector system comprising two connectors, and a method of manufacturing the contactless connector. In particular, the present invention provides a contactless connector comprising an inductive coupling element such as a coil. Further, there is provided an outer ferrite element surrounding at least part of the coil. The arrangement of the coil and the ferrite element allows the inductive transfer of power to / receives power from the mating contactless connector. Background technique [0002] The present invention relates generally to contactless connectors for inductive power transfer. Contactless power connectors are widely used due to their various advantages over conventional power connectors, namely due to e.g. high resistance to contact failure, unlimited mating cycles, low wear, protection against electric shock, sparking...
