High Density Array Connector Insert Fixture

       This article describes an auxiliary tool for the reliable
mechanical plugging of Harcons (high-density array connector) or
comparable/similar components into copper-plated throughholes of
circuit boards.

      About 60 Harcon stripes with about 30 Harcons each are plugged
at a spacing of 1.25 mm into each thermal conduction module TCM of
known multilayer circuit boards (total number of Harcons per circuit
board about 20,000).  For lack of suitable tools, the plugging is
done by hand and the main difficulty is to reliably plug the holding
stripe suspended Harcons into the copper-plated throughholes.
Tolerances occurring during the production of the Harcons as well as
deformation and hardening strain, caused by the holding stripe
breaking off on the connector side, adversely affect the spacing of
the connectors, making them difficult to insert.

      The main component of the described tool is the
centering/alignment comb consisting of two mirror-symmetrical single
combs.  The function and, in particular, the geometrical shape of the
centering/ alignment comb ensure that the connectors are reliably
seized, centered, aligned, and plugged and that inserted Harcons may
be removed undamaged.  The special shape of its teeth maximizes the
comb's centering area within the alignment space available (which is
limited on one side by a previously inserted row of Harcons).  In the
original position, the free ends of the single combs form a
gable-shaped centering area permitting the connectors...
