Abstract

A universal compact compression tool includes a vise assembly having different sets of jaws. The different sets of jaws are for holding different connectors during installation on a cable. A shaft on the tool is mounted to move between advanced and retracted positions with respect to the vise assembly. On the shaft, a plunger is mounted to move between first and second positions. In the first position of the plunger, the plunger is advanced on the shaft. In the second position of the plunger, the plunger is retracted on the shaft. The user sets the plunger in either the first or the second position depending on the type of connector to be installed on the cable. Once selected, and with the connector in the vise assembly, the user closes a lever of the tool to move the shaft to the advanced position, thereby applying the connector to the cable.

First claim

The invention claimed is:

1. A compression tool comprising:
a vise assembly including a first set of jaws and a different, second set of jaws, wherein the first set of jaws includes opposed major jaws mounted to pivot toward and away from each other in closed and open positions, respectively, and the second set of jaws includes opposed minor jaws mounted to pivot toward and away from each other in closed and open positions, respectively;
a shaft mounted for movement between an advanced position and a retracted position with respect to the vise assembly, wherein movement of the shaft from the retracted position to the advanced position thereby imparts movement to at least one of the first and second jaws from the open position to the closed position; and
a plunger mounted to the shaft such that the plunger can move between first and second helical positions with respect to the shaft;
wherein in the first position of the plunger, the plunger is advanced a first distance with respect to the shaft; and
in the second position of the plunger, the plunger is advanced a second distance with respect to the shaft, said second distance being different from the first distance.

2. The compression tool of claim 1 , further comprising a lever operatively coupled to the shaft and the first and second sets of jaws to move the shaft between the advanced and retracted positions thereof in response to closing and opening the lever, respectively, thereby imparting movement to the at least one of the first and second sets of jaws between the closed position and the open position.

3. The compression tool of claim 2 , wherein the lever is operatively coupled to close at least one of the first and second sets of jaws in response to closing the lever.

4. The compression tool of claim 1 , wherein the plunger is formed with a socket at a distal end of the plunger.

5. The compression tool of claim 1 , wherein the plunger moves in rotational movement on the shaft between the first and second positions.

6. The compression tool of claim 1 , wherein the first and second sets of jaws are coaxial.

7. The compression tool of claim 6 , wherein the first and second sets of jaws are axially spaced apart.

8. The compression tool of claim 1 , wherein:
the second set of jaws is mounted for pivotal movement between a closed position and an open position;
in the closed position of the second set of jaws, the second set of jaws is in front of the first set of jaws and is directly aligned with the plunger; and
in the open position of the second set of jaws, the second set of jaws is away from alignment with the plunger and the first set of jaws is directly aligned with the plunger.

9. A compression tool comprising:
a vise assembly configured to accommodate a first connector having a first dimension and a second connector having a different, second dimension;
the vise assembly comprising first and second sets of jaws, wherein the first set of jaws includes opposed major jaws mounted to pivot toward and away from each other in closed and open positions, respectively, and the second set of jaws includes opposed minor jaws mounted to pivot toward and away from each other in closed and open positions, respectively;
a shaft mounted for movement between an advanced position and a retracted position with respect to the vise assembly, wherein movement of the shaft from the retracted position to the advanced position thereby imparts movement to at least one of the first and second jaws from the open position to the closed position; and
a plunger mounted to the shaft such that the plunger can move between first and second helical positions with respect to the shaft;
wherein in the first position of the plunger, the plunger is advanced a first distance with respect to the shaft corresponding to the first dimension; and
in the second position of the plunger, the plunger is advanced a second distance with respect to the shaft corresponding to the second dimension.

10. The compression tool of claim 9 , further comprising a lever operatively coupled to the shaft and the first and second sets of jaws to move the shaft between the advanced and retracted positions thereof in response to closing and opening the lever, respectively, thereby imparting movement to the at least one of the first and second sets of jaws between the closed position and the open position.

11. The compression tool of claim 10 , wherein the lever is operatively coupled to close at least one of the first and second sets of jaws in response to closing the lever.

12. The compression tool of claim 9 , wherein the plunger is formed with a socket at a distal end of the plunger.

13. The compression tool of claim 9 , wherein the plunger moves in rotational movement on the shaft between the first and second positions.

14. The compression tool of claim 9 , wherein the first and second sets of jaws are coaxial.

15. The compression tool of claim 14 , wherein the first and second sets of jaws are axially spaced apart.

16. The compression tool of claim 9 , wherein:
the second set of jaws is mounted for pivotal movement between a closed position and an open position;
in the closed position of the second set of jaws, the second set of jaws is in front of the first set of jaws and is directly aligned with the plunger; and
in the open position of the second set of jaws, the second set of jaws is away from alignment with the plunger and the first set of jaws is directly aligned with the plunger.

17. A tool for compressing a connector onto a coaxial cable, the tool comprising:
a vise assembly comprising a first set of jaws and a different, second set of jaws, wherein the first set of jaws includes opposed major jaws mounted to pivot toward and away from each other in closed and open positions, respectively, and the second set of jaws includes opposed minor jaws mounted to pivot toward and away from each other in closed and open positions, respectively;
a shaft mounted for reciprocal movement between advanced and retracted positions with respect to the vise assembly, wherein movement of the shaft from the retracted position to the advanced position thereby imparts movement to at least one of the first and second sets of jaws from the open position to the closed position;
a plunger for compressing the connector in the vise assembly, the plunger mounted to the shaft such that the plunger can move between a first helical position and a second helical position on the shaft;
in the first position of the plunger and the advanced position of the shaft, the plunger is a first distance away from the vise assembly; and
in the second position of the plunger and the advanced position of the shaft, the plunger is a second distance away from the vise assembly, the first and second distances being different.

18. The compression tool of claim 17 , further comprising a lever operatively coupled to the shaft and the first and second sets of jaws to move the shaft between the advanced and retracted positions thereof in response to closing and opening the lever, respectively, thereby imparting movement to the at least one of the first and second sets of jaws between the closed position and open position.

19. The compression tool of claim 18 , wherein the lever is operatively coupled to close at least one of the first and second sets of jaws in response to closing the lever.

20. The compression tool of claim 17 , wherein the plunger is formed with a socket at a distal end of the plunger.

21. The compression to
