【正文】 ponents or assemblies. This is confirmed by the design being reviewed in the harness CAD tool set ? In determining w/h retention points, mockup a harness/bundle and install in representative sheet metal. This should illustrate how the w/h wants to naturally fit into the vehicle. Based on the customer39。s w/h specifications and requirements regarding routing and retention, the packaging engineer should chose appropriate retention points on the w/h What to do? Detailing and Dimensioning Training ? Additional considerations for determining retention points are: ? The size of the wire bundle。 likewise, heavy bundles should be supported to prevent their interference with other ponents。 sometimes the w/h must be routed to a preferred hole location Detailing and Dimensioning Training ? Additional considerations for determining retention points are: ? When two or more locators are used in a row, slotted holes should be considered to avoid tolerance stackup conditions. This aids operators in differentiating between wiring holes and nonwiring holes. A word of caution, though, as slotted holes do not adequately retain large wiring bundles Detailing and Dimensioning Training ? Dimensioning: ? Dimensioning wire assemblies is acplished with two different tolerance systems
