It is important to remember that an electrical connection is a set between :

- An unanemelled standard cable

- A terminal of dimensions corresponding to the cable

    -    A crimping die which correspond to the cable and to the terminal

The use of enamel wires or conductor wrapped in trades winding requires a quality approach which has not always implemented. This forgetting frequently led to significant failures in electrical systems.

The use of a standardized terminal and a non-standard cable corresponds to an "invention" that must be qualified with :

- Mechanical tests

- Electrical tests

- Visual tests
