1. An apparatus for testing the quality of an electrical connection of a test part, the apparatus comprising:
- a first fixture configured to hold an electrical terminal of a test part the electrical terminal having an electrical connection with a first section of an electrical conductor of the test part;
a second fixture configured to hold a second section of the electrical conductor wherein the second fixture is rotatable to apply a twist to the electrical conductor and impart a force on the connection between the first second of the electrical conductor and the electrical terminal; and
an electrical test module configured to measure an electrical resistance of the electrical connection between the electrical terminal and the electrical conductor of the test part when the twist is applied to the test part, the electrical test module including a first lead connected to the electrical terminal and a second lead connected to the electrical conductor.

16. A process to test an electrical connection quality of a test part comprising a connected terminal joined to an electrical conductor, the process comprising:
-
affixing a first section of the electrical conductor to an electrical terminal to form an electrical connection between the electrical conductor and the terminal; affixing the electrical terminal to a first fixture; affixing a second section of the electrical conductor to a second fixture; applying a twisting force to the test part; measuring an electrical resistance of the connection between the electrical terminal and the electrical conductor prior to the application of the twisting force and after the application of the twisting force; comparing the electrical resistances measured to a threshold electrical resistance; measuring the electrical resistance of the test part during the application of the twisting force; and determining whether the test part passed or failed based upon the comparing. - View Dependent Claims (17)
