Abstract

758,688. Couplings. SKILLMANN & CO., PTY., Ltd., T. S. April 5, 1954 [April 7, 1953], No. 9925/54. Class 38 (1). Terminal tags 4 ... 8 on a relay or other component are connected to conductors 10 ... 14 deposited on an insulating base plate 9 by passing the tags through apertures 15 ... 19 in the base plate, said apertures being larger than the tags by at least # inch in each direction and coincident with the conductors, bending the tags or moving the plate so that the tags touch the sides of the apertures and then soldering the tags to the conductors. The large apertures facilitate replacement of a component in that during unsoldering of the tags they can be bent away from their connecting point or if the plate is movable it can be moved so that the tags spring away from the conductors as they are unsoldered. The conductors need not embrace the apertures entirely (Fig. 3, not shown) and they may have portions 29, Fig. 4, lying within the apertures.
