electrical bus 10 is fed from areel 98 through a cablelength sensing station 100 to sense the length of cable that is to be removed fromreel 98.Bus 10 is fed to a terminatingstation 102 at which is located a table 104 along whichbus 10 moves and is held in position thereon by hold-downmembers 106 that can be actuated by electromagnetic means or air-or fluid-operated means.Branch bus 12 is fed fromreel 108 acrossmain bus 10 along table 104 withbus 12 passing by cablelength sensing station 110 that senses the length of cable that is desired to be removed fromreel 108. A program- controlled terminatingdevice 112 operates through anopening 114 in table 104 to automatically insertelectrical connectors connectors 116 fed to terminatingdevice 112 from a supply reel (not shown) thereby interconnecting the conductors ofbuses Electric motors 118 are operationally connected to terminatingdevice 112 to move the terminating dies thereof to their programmed locations for insertion of the electrical connectors into the crossed buses electrically connecting selected electrical conductors together. - After
bus 12 has been terminated tobus 10,bus 12 is cut from its supply andbus 10 is moved toinsulation applying station 120 at which insulatingtape 50 is applied tobus 10 covering the exposed legs of the connectors.Bus 12 is then moved to shield applyingstation 122 whereconductive foil 52 is adhesively secured to the bottom surface ofbus 10 whereafterhousing member 30 is positioned onto the terminated sections ofbuses - After
other branch buses 12 have been terminated tomain bus 10, insulatingtape 50 applied ontobus 10,conductive foil 52 secured thereto, andhousing members 30 secured in position over the terminated sections of the buses,bus 10 is then cut fromsupply reel 98 and a completed harness has now been made. If desired, onlyhousing member 30 can be positioned onto the terminated sections of the buses without applying insulating tape or conductive foil. Insulating tape and foil may be applied to both sides of the main and branch cables. - Figure 13 depicts a flow diagram for making a harness in accordance with the equipment illustrated in Figures 11 and 12, and the harness making operation can be under the control of a programmable controller that is microprocessor operated. Insulating tape can be applied onto main bus cable and branch bus cable if conductive foil is to be adhesively secured onto both sides of the main bus cable. If conductive foil is secured onto the main bus cable, then grounding
contact 54 is included in the housing member.
