Definitions

  • indentations be symmetrically spaced around the periphery of the contact, so that all the elements of the contact and inserted conductor will be maintained in a coaxial relationship.
  • indentations it is currently customary to provide four, equally angularly spaced and depthed, indentations in a common transverse plane through the contact. This is customarily accomplished by four indentors radially mounted through a transverse plane of a circular carrier which has a central axial hole to receive the contact.
  • the carrier is rotatable within an annular ring having an inner camming surface for each indentor, which indentors are spring loaded to extend without the carrier and abut the camming surfaces. Relative rotation between the carrier and cam ring forces the indentors to ride down the camming surfaces towards the center of the carrier to indent the contact.
  • each contact had to be individually, axially inserted into the carrier for indenting.
  • split carriers mounted between linearly reciprocating cams have also been used, these carriers also required the contact to be axially inserted. It will be appreciated that it was diflicult to provide a rapid feed of contacts to the indenting position in the carrier, when each contact had to be individually and axially inserted.
  • Another object of this invention is to provide an indentor assembly which permits very accurate adjustment of the depth of the indent made by each indentor.
  • Still another object of this invention is to provide an indentor assembly which permits the accurate timing of related machine functions, such as' contact feeding and contact detachment from its supporting belt.
  • Yet another object of this invention is to provide a novel contact supporting belt feed machanism.
  • a feature of this invention is a central rotatable plate carrying a plurality of peripheral cams to individually operate individual linkages which in turn operate the several indentors, feeding and separator mechanisms.
  • Another feature of this invention is a plurality of centrifugally directed indentor driving means interconnected by means of a plurality of force direction reversing means to a plurality of centripetally directed indentors.
