Patent ID: 7345639

Claim:
An automatic central buffer coupling for a multi-membered vehicle comprising: a first coupling head of a first car body, said first coupling head comprising a coupling element and a first contact plate; a second coupling head of a second car body, said second coupling head comprising a counter-coupling element and a second contact plate; a signal transmission device configured to transmit electric and/or electronic signals between the first car body and the second car body, said signal transmission device comprises said coupling element and said counter-coupling element; wherein said first coupling head and said second coupling head are configured such that a frictional connection can be produced in the coupled state between said first coupling head and said second coupling head and said coupling element is integrated in said first contact plate and said counter-coupling element is integrated in said second contact plate such that a face side of said coupling element is arranged in a contact plane common to said first coupling head and said second coupling head opposite a face side of said counter-coupling element; wherein said coupling element comprises at least one antenna member arranged in said first contact plate; wherein said counter-coupling element comprises at least one antenna member arranged in said second contact plate, said at least one antenna member of said coupling element and said at least one antenna member of said counter-coupling element configured such that a clearance results between said at least one antenna member of said coupling element and said at least one antenna member of said counter-coupling element when said first coupling head and said second coupling head are in the coupled state; and wherein each of said at least one antenna members comprises a disc monopole antenna configured to transmit data in the GHz frequency range.
