Abstract

Notches 1 are formed in the edges of faces 2 of polygonal mandrel 3 by a screw cutting technique. Wire 4 is then wound helically around mandrel 3 from bobbin 5 so that it registers in notches 1 and extends across the faces of mandrel 3 in parallel paths. Strips 6 of insulating material are placed over wire 4 on the faces and secured to the wire by an adhesive. Wire 4 can be lead-tin coated by an electroplating process before or after strips 6 are secured in position. Due to the presence of mandrel 3, the lead-tin coating is thickest on the side of wire 4 remote from mandrel 3 and near the edges of faces 2. The assembly is then cut longitudinally of mandrel 3 along lines 7 adjacent to each edge of faces 2 resulting in the production of a plurality of connectors.

The assembly is then cut longitudinally of mandrel 3 along lines 7 adjacent to each edge of faces 2 resulting in the production of a plurality of connectors. Each connector consists of a strip 6 of insulating material with parallel spaced transverse conducting wires 4 projecting beyond the longitudinal edges of a strip 6. Such a connector is flexible and can be soldered directly to conductors.
