Claims
- 1. A machine for preparing a cable for use in a cable termination assembly, such cable being of flat type including a plurality of conductors separated from each other an held in generally parallel and coplanar relationship by cable insulation, said machine comprising longitudinal slitter blade means for slitting the cable insulation between two relatively adjacent conductors of the cable in a longitudinal direction substantially parallel to such conductors, two transverse slitter blade means at respective longitudinal ends and transversely opposite sides of said longitudinal slitter blade means for slitting the cable insulation in a direction transverse to that of such conductors, said longitudinal and transverse slitter blade means operating to slit the cable insulation near an end of the cable to outline a tab of insulation at such end of the cable, and puller means for effecting relative longitudinal movement between the insulation tab and the conductors thereby to draw the ends of the conductors into such tab.
- 2. The machine of claim 1, wherein each slitter blade means includes a pair of opposed slitter blades relatively movable in a direction normal to the cable to slit the cable insulation.
- 3. The machine of claim 2, comrising a pair of opposed slitter members relatively movable in a direction normal to the cable, one slitter member including one slitter blade of each pair thereof and the other slitter member including the other slitter blade of each pair thereof.
- 4. The machine of claim 3, wherein the slitter blades of said transverse slitter blade means terminate short of the slitter blades of the longitudinal slitter blade means in their respective slitter members in a direction normal to the cable to prevent the slitter blades of the transverse slitter blade means from nicking the conductors in such cable when said slitter members are brought to engagement with each other for slitting the cable insulation.
- 5. The machine of claim 3, wherein each slitter member includes a block in which the respective slitter blades are integrally formed.
- 6. The machine of claim 4, wherein each block has plural pairs of surfaces intersecting at an included angle of about 45.degree. to form respective slitter blades therein.
- 7. The machine of claim 3, wherein said slitter members have a substantially identical pattern of slitter blades therein positioned in alignment with corresponding slitter blades in the other slitter member.
- 8. The machine of claim 1, wherein there are two of said longitudinal slitter blade means which are transversely spaced apart and longitudinally coextensive, and three of said transverse slitter blade means, one extending transversely between said two longitudinal slitter blade means at one end thereof and the other two respectively extending transversely outwardly from said two longitudinal slitter blade means at the other end thereof.
- 9. The machine of claim 1, wherein said puller means moves in a longitudinal direction substantiallly parallel to the conductors by a predetermined amount adequate to draw one of such relatively adjacent conductors fully out from the tab but not the other of such relatively adjacent conductors whereby the tab may be used to facilitate manipulation of the latter conductor.
- 10. The machine of claim 1, wherein said puller means includes deforming means for deforming plastically at least a portion of the cable insulation at a location spaced from such end of the cable.
- 11. The machine of claim 10, wherein said deforming means includes relatively movable members and means for moving the same with respect to each other to crimp a pattern of relatively raised and recessed portions in the cable insulation.
- 12. The machine of claim 11, wherein said relatively movable members include a pair of crimping blocks, each crimping block having a pattern of relatively raised and recessed areas aligned with each other in out of phase position.
- 13. The machine of claim 12, wherein at least one of said crimping blocks includes guide passage means for guiding a cable therethrough into alignment with said slitter means and deforming means.
- 14. The machine of claim 1, further comprising deforming means for deforming at least a portion of such insulation at a location spaced from such end of the cable.
- 15. The machine of claim 14, wherein said deforming means includes relatively movable members and means for moving the same with respect to each other to crimp a pattern of relatively raised and recessed portions in the cable insulation.
- 16. A machine for preparing a cable for use in a cable termination assembly, such cable including at least one conductor and insulation, said machine comprising slitter means for slitting such insulation near an end of such cable to define a tab of severed insulation at such end of the cable and to hold such tab of insulation at its severed end, crimping means for crimping a length of the cable insulation at a location spaced from such end of the cable to form at least one recess in the cable insulation and then to hold the cable at such recess, and means for moving said crimping means away from said slitter means a predetermined distance in a longitudinal direction parallel to the cable while the slitter means holds stationary the tab of insulation thereby to draw the end of the conductor into the tab of insulation.
- 17. The machine of claim 16, wherein said slitter means includes at least one slitter member including longitudinal slitter blade means for slitting insulation of such cable in a longitudinal direction substantially parallel to the conductor and transverse slitter blade means for slitting insulation in a direction transverse to that of the conductor.
- 18. The machine of claim 16, wherein said crimping means includes a pair of relatively movable members and means for moving the same with respect to each other to crimp a pattern of relatively raised and recessed portions in the cable insulation.
- 19. The machine of claim 18, wherein at least one of said movable members includes guide passage means for guiding a cable therethrough into alignment with said slitter means.
- 20. The machine of claim 16, wherein said crimping means includes a pair of relatively movable members and means for mounting said movable members for generally arcuate movement, and said means for moving includes means operable to move said movable members in respective generally arcuate paths.
- 21. A machine for preparing a cable for use in a cable termination assembly, such cable including at least one conductor and insulation, said machine comprising two pairs of blocks defining between the blocks of each pair a respective portion of a longitudinal slot for receiving the cable to be prepared, one pair of blocks including slitter blocks relatively movable in a direction normal to such longitudinal slot to slit the insulation at slitter blades therein near an end of the cable to define a tab of insulation at such end, and the other pair of blocks including crimping blocks relatively movable in a direction normal to such longitudinal slot to crimp the cable insulation at a location spaced from such end of the cable, and means for relatively moving said pairs of blocks a predetermined distance in a longitudinal direction parallel to the cable while the slitter and crimping blocks respectively hold the insulation tab and cable to draw the end of the conductor into such tab.
