Embodiment Construction

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

[0038] figure 1 A partial exploded view of the base piece of the contactless connector 100 that can be inductively connected to the corresponding mating connector is shown. The contactless connector 100 therefore has a mating end 101 for interaction with a suitable mating connector (however, not shown in the figure), so that contactless power transfer and optionally additional signal transmission is possible. The inductive coupling element 110, in this example a coil with multiple windings 115, is configured to inductively transfer energy to the corresponding mating connector. The first and second contact leads 103, 104 supply current to and receive current from the winding 115.

[0039] The external ferrite element 107 is provided and arranged such that it at least partially surrounds the inductive coupling element. This results in improved guidance of the B field tow...

Abstract

Contactless connector (100) for inductively connecting a corresponding mating connector at a mating end (101), comprising an inductor for transmitting power to and / or receiving power from the corresponding mating connector Coupling element (110) and external ferrite element (107) surrounding the inductive coupling element (110). An external ferrite element (107) is magnetically coupled to a base plate (105) which includes at least one lead through hole (109) for receiving at least one contact lead (110) connected to the inductive coupling element (110) 103,104). Only one lead through hole (109) is provided for accommodating two contact leads (103, 104) connected to the inductive coupling element (110) so that the contact leads carry current in opposite directions. Alternatively, the base plate (105) is formed with at least one air gap (114, 116, 117) arranged in a magnetic field circuit excited by current flowing through the at least one lead.

Description

Technical field [0001] The present invention relates to a contactless connector for inductive connection to a corresponding mating connector, a contactless connector system including two connectors, and a method of manufacturing the contactless connector. Specifically, the present invention provides a contactless connector including an inductive coupling element such as a coil. Further, an external ferrite element surrounding at least part of the coil is provided. The arrangement of the coil and the ferrite element allows power to be inductively transmitted to / received from the mating contactless connector. Background technique [0002] The present invention generally relates to contactless connectors for inductive power transmission. Contactless power connectors are widely used because of their various advantages over conventional power connectors, namely, due to, for example, high resistance to contact damage, unlimited mating cycles, low wear, anti-shock, sparking, and curre...
