Abstract: A fixture (60) for holding a pin-supporting shuttle (54) during assembly therein of terminal pins (20) for later insertion into a rigid board is formed with a sloping work surface (66) including a plurality of locating pins (68 and 70) for holding the shuttle (54) in two dimensions and a plurality of hold-down clips (74) for engagement with a groove (76) in the shuttle. A locking bar (72) positioned above the shuttle (54) is movable toward and away from the shuttle and carries a guide (136) for the location of assemblies (44 or 52) of terminal pins (20) in the shuttle. When the shuttle (54) has been fully loaded, the locking bar (72) is moved toward the shuttle to operate a securing mechanism (116) of the shuttle to secure the terminal pins (20) into the shuttle. A break-off groove (84) is located above a scrap chute (86) and is used for breaking pin-carrier strips (40 and 42) from the shuttle-mounted pin (20) after assembly.
