Abstract

The device uses a long strip formed with a plurality of small separate terminal inserts and employs a method for rapidly inserting a succession of such inserts into a jig for molding a plastic board or frame. As As shown in connection with a magnetic memory core frame 11, scores of terminal inserts 12 are required to be first held to extend inwardly from the four sides of a jig frame 9. They are then molded in an evenly spaced formation along each of the four outer edges of frame 11 molded on the terminals.

Expandable Terminal Insert Strip

The device uses a long strip formed with a plurality of small separate terminal inserts and employs a method for rapidly inserting a succession of such inserts into a jig for molding a plastic board or frame. As As shown in connection with a magnetic memory core frame 11, scores of terminal inserts 12 are required to be first held to extend inwardly from the four sides of a jig frame 9. They are then molded in an evenly spaced formation along each of the four outer edges of frame 11 molded on the terminals.

The continuous strip 10 is formed with a procession of terminal inserts 12. These are held together temporarily by removable selvage edge strips 13 and
14. Strips 13 are cut or slotted as at 15, 16 and 17 alternately and equidistantly on opposite sides of strip 10. Such slotting 15... 17 is not merely through the selvage portions. It runs into the large openings between terminals 12 so that, in effect, slot 15 extends across to edge 13, slot 16 extends back to edge 14, etc. There is a regular succession of such long overlapping cross slots. This results in a strip 10 having unusual flexibility in all directions and capacity for expansion and contraction lengthwise. This is important for use over long stretches without undue emphasis on accurate spacing.

In constructing jig 9 and mold for core frame 11, jig notches 19 for temporarily holding terminals 12 must be spaced to allow for plastic material shrinkage. The mold used to produce a core frame has different spacing for terminals than th...
