Abstract

Abstract Disclosed is a method and apparatus for notching a flat multi-conductor ribbon cable of the type having an encapsulating shielding medium completely surrounding each cable conductor and filling the spaces therebetween, and an outer jacket surrounding the encapsulating medium. According to the method, the outer jacket and the shielding medium are cut along two spaced-apart lines generally transverse to the conductors. Thereafter, the jacket and the shielding medium are cut along spaced-apart lines parallel and immediately adjacent to each conductor, thereby forming a plurality of slugs which are pushed from between adjacent conductors to expose the conductors in the termination region. The above-described method is carried out in an apparatus having blades which cut the jacket and the resilient medium along the transverse spaced-apart lines. Blade-like notching members have a width corresponding to the space between adjacent conductors, and a lower cable engaging surface which includes an extended cutting edge and a recessed surface which pushes the slug from the termination region.
