Abstract

One embodiment includes a method for protecting from the accidental application of an electrical potential to an incorrect pin of a multipin electrical connector during testing. A sleeve is fitted around a pin that is not to have potential applied to it such that the pin is protected from accidental application of potential during testing.

First claim

The invention claimed is:

1. A method of performing a pin injection test through a multipin electrical connector, the method comprising:
identifying pins which are not to have potential applied during the pin injection test;
fitting an electrical insulating sleeve around each identified pin to prevent potential from being applied to the identified pin; and
performing a pin injection test at pins of the multipin electrical connector that are not fitted with one of the electrical insulating sleeves.

2. The method of claim 1 wherein the electrical insulating sleeve is fitted around a protruded portion of the identified pin.

3. The method of claim 1 wherein the electrical insulating sleeve is a heat shrink sleeving.

4. The method of claim 3 wherein the heat shrink sleeving is fitted around the identified pin by applying heat such that the heat shrink sleeving is shrunk onto the contour of the identified pin.

5. The method of claim 1 wherein fitting an electrical insulating sleeve is performed while the identified pin is in place within the electrical connector.

6. The method of claim 1 wherein fitting an electrical insulating sleeve is performed by removing the identified pin from the multipin electrical connector, fitting the electrical insulating sleeve around the identified pin, and installing the identified pin back inside the multipin electrical connector.

7. A method comprising:
identifying pins of a multipin electrical connector which are not to have potential applied during testing;
fitting pins which are not to have potential applied with electrical insulating sleeves; and
performing a test at pins which are not fitted with electrical insulating sleeves.

8. The method of claim 7 wherein the electrical insulating sleeves are heat shrink sleeving.

9. The method of claim 8 wherein the heat shrink sleeving is fitted around the identified pin by applying heat such that the heat shrink sleeving is shrunk onto the contour of the pin.
