Cable stripper having an adjustable bushing
View Patent ↗A cable stripper is provided which has an adjustable bushing which can be adjusted to accept a variety of differently size cables. The cable stripper is rotated around the cable to strip the insulation from a cable. The cable stripper can be attached to an existing tool to impact rotation of the cable stripper around the cable. The cable stripper includes a bushing having an axial passageway and a plurality of spaced slots which are in communication with the passageway, a plurality of cable retention blocks attached to the bushing, and a blade member mounted on the bushing, the blade member being seated within the passageway. The cable retention blocks are moveable relative to the bushing to pass through the slots and into the passageway to engage the cable mounted within the passageway.
1. A cable stripper capable of stripping insulation from a cable, the cable stripper comprising:
a bushing comprising a mounting plate and a shaft extending outwardly therefrom, a passageway extending axially therethrough and a plurality of spaced slots provided through the shaft and in communication with the passageway;
a plurality of cable retention blocks movably attached to the mounting plate and extending through the slots and into the passageway; and
a locking ring having a passageway through which the shaft passes, the locking ring being movable along a longitudinal axis of the shaft, the locking ring being capable of being engaged with one of the mounting plate and the cable retention blocks, wherein when the locking ring is engaged, movement of the cable retention blocks relative to the bushing in at least a radially outward direction is prevented, the locking ring being capable of being disengaged therefrom to allow movement of the cable retention blocks relative to the bushing in at least the radially outward direction; and
a blade member movably mounted on the bushing, the blade member configured to be at least partially seated within the passageway.
2. The cable stripper of claim 1 , wherein the mounting plate is rotationally attached to the shaft.
3. The cable stripper of claim 2 , wherein the mounting plate includes a plurality of partially spiral shaped grooves, each cable retention block having a pin seated within one of the respective grooves and slidable within the respective groove.
4. The cable stripper of claim 1 , wherein one of the bushing and at least one of the cable retention blocks includes a pin and the other of the bushing and at least one of the cable retention blocks includes a slot, the pin is seated in the slot and slidable relative to the slot.
5. The cable stripper of claim 1 , wherein the cable retention blocks are pivotable relative to the bushing.
6. The cable stripper of claim 5 , wherein the cable retention blocks have an angled surface which is engageable with the locking ring to cause the pivotal movement.
7. The cable stripper of claim 1 , wherein the bushing further comprises a second shaft extending from the mounting plate, the passageway further extending through the second shaft, the second shaft having an aperture therethrough in communication with the passageway.
8. The cable stripper of claim 7 , wherein a portion of the first-defined shaft is threaded and the locking ring is threadedly engaged with the portion.
9. The cable stripper of claim 1 , wherein a portion of the shaft is threaded and the locking ring is threadedly engaged with the threaded portion.
10. The cable stripper of claim 1 in combination with a tool, the tool configured to rotate the cable stripper relative to a stationary cable.
11. The cable stripper of claim 1 in combination with a tool comprising a body attachable to and detachable from the bushing.
12. The combination of claim 11 , wherein a rotational axis of the tool and a rotational axis of the cable stripper are linearly aligned.
13. The combination of claim 11 , wherein the bushing includes an aperture and the tool includes a spring-loaded pin which is engageable with the aperture.
14. The cable stripper of claim 1 in combination with a tool, the tool configured to rotate the cable stripper relative to a stationary cable.
15. The cable stripper of claim 4 , further comprising a spring configured to bias the cable retention blocks relative to the bushing.
16. The cable stripper of claim 5 in combination with a tool, the tool configured to rotate the cable stripper relative to a stationary cable.
