Abstract

A spin weld apparatus for spin welding a prepared end of a coaxial cable with a coaxial connector includes a cable clamp dimensioned to grip the coaxial cable and a drive collet dimensioned to enclose and rotationally interlock with a lateral surface of the coaxial connector. The drive collet is dimensioned to rotationally interlock with an interlocking portion of a spin welder. The spin welder is dimensioned to axially align the coaxial connector with the coaxial cable for spin welding when the drive collet is rotationally interlocked with the spin welder.

First claim

I claim:

1. A spin weld apparatus for spin welding a prepared end of a coaxial cable with a coaxial connector, the spin weld apparatus comprising:
a cable clamp dimensioned to grip the coaxial cable;
a drive collet dimensioned to enclose a longitudinal extent of the coaxial connetor and rotationally interlock with a lateral surface of the coaxial connector;
the drive collet dimensioned to rotationally interlock with an interlocking portion of a spin welder; and
the spin welder dimensioned to axially align the coaxial connector with the coaxial cable for spin welding when the drive collet is rotationally interlocked with the spin welder.

2. The spin weld apparatus of claim 1 , wherein the drive collet is provided with a first collet portion and a second collet portion; and
the first collet portion separable from the second collet portion for seating the coaxial connector within the drive collet.

3. The spin weld apparatus of claim 1 , wherein at least one end of the drive collet is provided with a flange extending radially inward, short of contacting the coaxial cable.

4. The spin weld apparatus of claim 1 , wherein the interlocking portion is provided with a spindle socket dimensioned to receive and rotationally interlock with the drive collet; and
the interlocking portion is coupled with a spindle of the spin welder.

5. The spin weld apparatus of claim 4 , wherein the interlocking portion is provided with a plurality of spring detent screw apertures extending from an outer diameter to the spindle socket; and
one of a plurality of spring detent screws is provided within each of the spring detent screw apertures.

6. The spin weld apparatus of claim 1 , further including a stop for stopping the coaxial cable at a desired longitudinal position within the cable clamp.

7. The spin weld apparatus of claim 6 , further including an actuator coupled with the stop; and
the actuator operable to move the stop with respect to the cable clamp.

8. The spin weld apparatus of claim 7 , wherein the stop is provided with a
pivot end and an attachment end;
the pivot end pivotally coupled with a cable clamp base;
the attachment end removably coupled with the cable clamp base; and
the stop stopping the coaxial cable when the attachment end is coupled with the cable clamp base.

9. The spin weld apparatus of claim 7 , wherein the cable clamp is provided with a top cable clamp portion and a bottom cable clamp portion; and
the top cable clamp portion movably coupled with the bottom cable clamp portion on one side.

10. The spin weld apparatus of claim 1 , further including a plurality of cams coupled to the interlocking portion; the cams operable to drive a plurality of wedge portions of the drive collet radially inward.

11. The spin weld apparatus of claim 10 , wherein each of the cams is coupled to a respective pivot pin; the pivot pins longitudinally displaceable by a drive plate;
and the drive plate longitudinally displaceable by at least one drive pin coupled to the spin welder.

12. The spin weld apparatus of claim 10 , wherein each of the wedge portions is radially slidable within a wedge slot of the drive collet.

13. The spin weld apparatus of claim 10 , wherein the wedge portions interfere with each other to define a minimum inward travel of the wedge portions.

14. The spin weld apparatus of claim 10 , wherein the wedge portions are retained upon the drive collet by at least one retaining arm.
