A METHOD FOR CONNECTING STRUCTURAL ELEMENTS

摘要

An assembly of a first, second and a third element, wherein the first element comprises a plurality of co-extending electrical conductors and at least two recesses having different shapes and within which electrical conductors are exposed. The second and third elements each have a part for introduction into one of the recesses so that a "mechanical coding" is obtained where the part of the second element obtains electrical contact to one group of electrical conductors of the first element and the part of the third element a second group. Also, a drill is claimed for providing recesses in an element having a plurality of co-extending electrical conductors without shorting these conductors.
