Module Pin Reformer

Parallel circuit module leads or pins of one grid size can be reformed to a smaller grid size without damage to the pin bases, by using pairs of relatively movable slides.

A module 1 is placed in nest 2 with its terminal pins 3 extending downward. The pins enter corresponding holes 4 in pairs of quadrature slides 5 and 6 beneath the nest. The upper tier of slides is four hold blades 5 of which two are shown; the four slides in the second tier are form blades 6, again with only two shown. Beneath the tiers of slides is a plate 7 with holes 8 and grooves 9, which receive the lower ends of the pins of an Inserted module. The slides are aligned by guides in base 10 and maintained in position by covers 11.

After a module is seated, form blades 6 are each retracted by a ring cam, not shown, so that pins in the holes in each blade are drawn against restraining surfaces 12 of the hold blades 5. These surfaces prevent bending of the pins 3 near the module body. The lower ends of the pins extending below the form blades 6 engage holes 8 and grooves 9, Which maintain perpendicularity of the pin ends with the module body. Thereafter, the hold-blades 5 are retracted slightly by the cam mechanism to release the pins 3. An ejector, not shown, can be used to push the module 1 from the nest 2.
