The e.g. aluminium support plate (2) is regularly perforated with octagonal holes (3). Each circuit (1) is firmly held against the plate, along a designated route, by regularly applied securing collars, clipped between convenient pairs of perforations. Contact between adjacent circuits is prevented by separating pegs (5), inserted in suitably chosen holes. Each peg comprises a cylindrical rod rising from a conical foot, whose underface, resting on the support plate, is separated by a neck, as deep as the plate thickness, from a smaller inverted conical base. The latter's resilience allows it to pass through the chosen perforation, followed by the neck, and the peg is then held on the plate by the opposed bases of the two conical sections. |
