Abstract

A tool for crimping a cable connector ( 6 ) comprises a first, U-shaped arm ( 3 ) which defines a seat in which the connector ( 6 ) may be accommodated in the working position; a second, compression arm ( 1 ) suitable for exerting a compression force on the connector ( 6 ), comprising a compression profile ( 5 ) at one end thereof, which, in turn, comprises a number of rotation pins which project laterally outwards from the compression profile ( 5 ) and are suitable for penetrating into corresponding holes in a branch of the first arm ( 3 ), to keep the second, compression arm ( 1 ) joined to the first arm ( 3 ).

First claim

The invention claimed is:

1. A tool for crimping a cable terminal together with a connector, the cable terminal including a plurality of wires, and the connector including a plurality of terminals; the plurality of wires of the cable terminal being introduced one by one into the plurality of terminals of the connector; the tool comprising: a first arm which defines a seat in which the connector is accommodated in the working position; a second, compression, arm suitable for exerting a uniform compression force on the connector; the second, compression, arm including a pressing profile at one end thereof, which, in turn, comprises two rotation pins which project laterally outwards from the pressing profile, and penetrate into corresponding holes in a branch of the first arm to keep the second, compression, arm joined to the first arm, the rotation pins forming a rotation shaft for the second, compression, arm; a single horizontal plane extending through the rotation shaft and the pressing profile in a moving direction of the connector; the pressing profile having a curved shape for exerting the uniform compression force on the connector while remaining in the single horizontal plane of the connector throughout an entire rotation of the second, compression, arm to crimp the cable terminal and the connector together, the cable terminal and the connector being removable from the seat of the first arm of the tool as one unit.

2. The tool according to claim 1 , wherein the first arm comprises holes in both U-shaped branches suitable for receiving the rotation pins in either of the branches of the first arm.

3. The tool according to claim 1 , wherein the physical dimensions of the pressing profile of the second, compression, arm are adapted to the type of connector to be crimped.

4. The tool according to claim 1 , wherein the second, compression, arm has a first length that extends beyond a length of the first arm when in a closed working position.

5. The tool according to claim 1 , wherein the rotation shaft is located in a horizontal plane parallel to the seat of the first arm.

6. The tool according to claim 1 , wherein the pressing profile is shaped to provide constant contact with the connector in the single horizontal plane as the second, compression, arm is rotated.

7. The tool according to claim 1 , wherein the first arm has U-shaped configuration.

8. A tool for crimping a cable comprising:
a first arm having a base, the base defining a seat for receiving a connector and a cable terminal that are crimped together therein;
a second, compression, arm adapted to exert a compression force on the connector, the second, compression, arm including a pressing profile at one end thereof, the pressing profile having rotation pins that project laterally outwards from opposing sides of the pressing profile, the rotation pins forming a rotation shaft for the second, compression, arm, a single horizontal plane extending through the rotation shaft and the pressing profile parallel to a forward direction of the connector, the pressing profile having a curved shape for exerting a uniform compression force on the connector while remaining in the single horizontal plane of the connector throughout an entire rotation of the second, compression, arm to crimp the cable terminal and the connector together, the cable terminal and the connector being removable from the seat of the first arm of the tool as one unit.

9. The tool according to claim 8 , wherein the second, compression, arm has a first length that extends beyond a length of the first arm when in a closed working position.

10. The tool according to claim 8 , wherein the rotation shaft is located in a horizontal plane parallel to the seat of the first arm.

11. The tool according to claim 8 , wherein the pressing profile is shaped to provide constant contact to the connector while the second, compression, arm is rotated from an open working position towards a closed working position.

12. The tool according to claim 8 , wherein the pressing profile is shaped to provide constant contact with the connector being crimped as the second, compression, arm is rotated.

13. A tool for crimping a cable comprising:
a base having a first branch end and a second branch end opposite the first branch end, the base defining an opening at the first branch end to form two opposing post defining apertures therein, the base having a longitudinal axis between the first and second branch ends;
a lever pivotally connected to the base and having a pressing profile for exerting a uniform compression force on a connector and against the second branch end of the base;
rotation pins mounted transversely to the longitudinal axis of the base, the rotation pins forming a pivot shaft for pivotally mounting the lever, the rotation pins engaging the apertures of the two opposing posts for mounting the lever to the base;
a seat defined by the base between the first and second branch ends, the seat having a connector that is longitudinally translatably guided in the seat toward a cable terminal upon the pressing profile of the lever when the lever is rotated from an open working position towards a closed working position; and
a single horizontal plane extending through the pivot shaft and the pressing profile parallel to a forward direction of the connector, the pressing profile having a curved shape for exerting the uniform compression force on the connector while remaining in the single horizontal plane of the connector throughout an entire rotation of the lever to crimp the cable terminal and the connector together, the cable terminal and the connector being removable from the seat of the base of the tool as one unit.

14. The tool according to claim 13 , wherein the rotation pins projects outwardly from opposing sides of the pressing profile.

15. The tool according to claim 13 , wherein the two opposing posts each define a recess gap at a top surface of the two opposing posts.

16. The tool according to claim 13 , wherein the pressing profile is shaped to provide constant contact with the connector being crimped as the lever is rotated.

17. The tool according to claim 13 , wherein the lever has a first length that extends beyond a length of the base when in the closed working position.

18. The tool according to claim 13 , wherein the pivot shaft is located in a horizontal plane parallel to the seat of the base.
