Abstract

A tool for crimping at least two members together and confirming that the crimp is acceptable. The tool includes a pair of opposed clamping jaws. Each of the clamping jaws has a crimping surface that contacts at least one of the members when crimping the members together. The tool also includes a pair of opposed arms that move the crimping surfaces of the opposed clamping jaws toward one another to define a crimping position and away from one another to define a release position. The tool also includes a gauge that defines a first size determining member that allows receipt of the members crimped together and a second size determining member that rejects receipt of the members crimped together.

Claims

1. A tool for crimping at least two members together and confirming that the crimp is acceptable, the tool comprising:

a pair of opposed clamping jaws, each of the damping jaws including a crimping surface that contacts at least one of the members when crimping the members together;

a pair of opposed arms that move the crimping surfaces of the opposed clamping jaws toward one another to define a crimping position and away from one another to define a release position;

a gauge defining a first size determining member allowing receipt of the at least two members crimped together and a second size determining member rejecting receipt of the at least two members crimped together, wherein the gauge is separate from the crimping surfaces and is attached to one of the arms; and

a finger spring that provides frictional resistance to the gauge to partially retard rotation of the gauge about the arm to which the gauge is attached.

2. The tool of claim 1, wherein the gauge is adapted to rotate between a stowed position in which the first and second size determining members are within the arm to which the gauge is attached and a measuring position in which the first and second size determining members are displaced from the arm to which the gauge is attached.

3. The tool of claim 2, wherein the finger spring is cantileverly supported by the arm to which the gauge is attached so as to define a fixed end and a free end of the finger spring.

4. The tool of claim 3, wherein the gauge including a mounting end that is pivotably connected to the arm to which the gauge is attached, wherein the mounting end includes a cam surface that selectively engages the free end of the finger spring when the gauge is rotated between the stowed position and the measuring position.

5. The tool of claim 3, wherein the free end of the finger spring is biased so as to be disposed within the arm to which the gauge is attached when the gauge is in the stowed position, and displaced from and not within the arm to which the gauge is attached when the gauge is rotated between the stowed position and the measuring position.

6. The tool of claim 1, wherein the pair of opposed arms each including a gripping surface adapted to receive force to cause the crimping surfaces of the damping jaws to move toward one another.

7. The tool of claim 6, wherein the finger spring is disposed between the gripping surfaces of the opposed arms.

8. A tool for crimping at least two members together and confirming that the crimp is acceptable, the tool comprising:

a pair of opposed clamping jaws, each of the clamping jaws including a crimping surface that contacts at least one of the members when crimping the members together;

a pair of opposed arms that move the crimping surfaces of the opposed clamping jaws toward one another to define a crimping position and away from one another to define a release position; and

a gauge defining a first size determining member allowing receipt of the at least two members crimped together and a second size determining member rejecting receipt of the at least two members crimped together, wherein the gauge is at least partially received within one of the arms.

9. The tool of claim 8, wherein the gauge is adapted to rotate between a stowed position in which the first and second size determining members are within the arm to which the gauge is attached and a measuring position in which the first and second size determining members are displaced from and not within the arm to which the gauge is attached.

10. The tool of claim 9, wherein the pair of opposed a s each include a gripping end that is opposite an end adjacent the clamping jaws, the gripping end of each of the opposed arms having a grip adapted to receive force to cause the crimping surfaces of the clamping jaws to move toward one another, the grip defining a gauge slot that receives the gauge when the gauge is in the stowed position.

11. The tool of claim 9, wherein the gauge includes an indicia face with indicia proximal to the first and second size determining members so that a user of the tool can differentiate between the first and second size determining members, the gauge also including a non-indicia face that is opposite the indicia face, and a measuring surface that extends from the indicia face to the non-indicia face.

12. The tool of claim 9, wherein the opposed arms are each defined by plate members spaced apart from one another so that the gauge can be received within the arm to which the gauge is pivotably attached.

13. The tool of claim 12, wherein the plate members each include interior surfaces that face one another and are generally parallel to one another.

14. The tool of claim 13, wherein the gauge includes an indicia face with indicia proximal to the first and second size determining members so that a user of the tool can differentiate between the first and second size determining members and an oppositely directed non-indicia face, wherein the indicia face and the non-indicia face are generally parallel to one another and to the interior surfaces of the arm to which the gauge is pivotably attached.

15. A tool for crimping at least two members together and confirming that the crimp is acceptable, the tool comprising:

a pair of opposed clamping jaws, each of the clamping jaws including a crimping surface that contacts at least one of the members when crimping the members together;

a pair of opposed arms that move the crimping surfaces of the opposed clamping jaws toward one another to define a crimping position and away from one another to define a release position; and

a gauge pivotably attached to one of the arms, the gauge including a body that defines a first size determining member allowing receipt of the members crimped together and a second size determining member rejecting receipt of the members crimped together, the gauge further including a stop member that allows only limited rotation of the gauge about the arm to which the gauge is pivotably attached.

16. The tool of claim 15, wherein the opposed arms are each defined by plate members spaced apart from one another so that the gauge can at least partially be received within the arm to which the gauge is pivotably attached, wherein the stop member prevents the gauge from rotating completely past the plate members.

17. The tool of claim 16, wherein the stop member extends perpendicularly from the body of the gauge so that the gauge has an L-shaped cross-section.

18. The tool of claim 15, wherein the body defines a pivot bore that receives a gauge pin for attachment of the gauge to the arm, wherein a middle post is between the pivot bore and the exterior post.

19. The tool of claim 15, wherein the gauge includes an indicia face with indicia proximal to the first and second size determining members so that a user of the tool can differentiate between the first and second size determining members, the stop member includes a stop face adapted for contact with the arm to which the gauge is pivotably attached so as to prevent complete rotation of the gauge, wherein the stop face is generally perpendicular to the indicia face.

20. The tool of claim 19, wherein the gauge includes a non-indicia face that is opposite the indicia face, and wherein the first size determining member defines a first measuring surface that transversely extends between the indicia face and the non-indicia face.
