ABSTRACT:
A method of forming wire harnesses and a cylindrical body pin assembly for connection to a peg board of the type used to form such harnesses is disclosed. The pin assembly comprises a cylindrical pin body and a cylindrical drive nut that are rotated relative to each other to axially move a pair of wire fingers protruding from one end of the pin body. The fingers are received within a hole in the peg board and are moved axially over a spreader disposed between them to separate the fingers and cause an enlarged shoulder on the fingers to abut against the peg board. After a selected number of pin assemblies have been installed in the peg board, wires may be wound around them to form the harness. The outer cylindrical surfaces of the pin body and drive nut are substantially equal in diameter to provide relatively straight, smooth sidewalls. This allows rapid installation and removal of the pin assembly by hand-held or robotic installation tools and, further, prevents the completed harness from catching on the pin assemblies during removal from the peg board, which could cause damage to the harness.
