Abstract

An inductive coupler for vehicles, comprising a first half (1) and a second half (2) which may be coupled to each other to transfer electrical energy through an alternating magnetic flux (3) therebetween. The first half contains a primary coil (17) for generating said flux, and the second half contains a secondary coil (27) for generating an electrical voltage derived from said flux. An electrical coupler for vehicles, comprising a first half and a second half which may be coupled to each other to transfer electrical energy through ohmic contacts therebetween. The first half contains a first contact plate (54), and the second half contains the corresponding second contact plate (64). The connector also includes means for attaching the first half to the second half such as to achieve ohmic contacts therebetween.
