a machine and method are disclosed for attaching a coaxial connector to the end of a coaxial cable . the machine seats the cable end having a preassembled contact into the connector housing , latching the contact in place , then conducts a pull test to verify proper latching . the jaws that grip the cable during insertion of the contact and pull testing are used to push the ferrule over the braided signal conductor prior to crimping the ferrule . a single air cylinder is used , at a relatively low pressure , to seat the contact and at a relatively high pressure to seat the ferrule . a constant force return spring is used to apply a predetermined test force to the jaws during the pull test . a high voltage test may be conducted at two points in the operating cycle .
