Abstract

A crimp tool includes a frame, a lead screw and a nut assembly connected to the lead screw. A spring member is connected to the frame and movable with rotation of the lead screw. A first transducer is connected to the nut assembly to measure a first force applied on the nut assembly. A second transducer is connected to the spring member to measure a second force applied thereon by the spring member.

Claims (11)

1. A crimp tool, comprising:

a frame;

a fixed conductive die connected to said frame;

a movable conductive die connected to said frame;

a first non-conductive member disposed between said frame and said fixed die; and

a second non-conductive member disposed between said frame and said movable die; and

an electrical component electrically connected to said fixed and movable conductive dies, such that an electrical circuit between said electrical component and said fixed and movable dies is closed during a poor crimp, said first and second non-conductive members prevent said electrical circuit from being closed during a good crimp.

2. The crimp tool according to claim 1 , wherein

wherein said electrical component is an ohm reader.

3. The crimp tool according to claim 1 , wherein

complementary surfaces of said first and second non-conductive members extend beyond complementary surfaces of said fixed and movable dies.
