Style 1 and Style 2 Backshells

It is a simple fact that the front end of the backshell must fit the rear end of the connector shell. Likewise the rear end
of the backshell must be large enough to accept the cable or wire bundle. When the target connector selected for an
application is small, but the cable entry diameter selected is large, then a style 2 design (shown below) will automatically
be produced by the factory. The stepped design of the Style 2 accomodates large shielded cables terminated to small connectors.
