## Abstract

A crimp tool for crimping contacts onto wire cable ends includes an indentor mechanism having a plurality of moveable indentors for deforming a portion of a contact inserted into the mechanism. One of the indentors has a pressure responsive element for providing a signal indicative of the pressure exerted on the contact by the indentor. A device coupled to the pressure responsive element records pressure data and transfers data to an electronic control unit for determining operation of the mechanism. An automated inspection system uses light projection and a light sensor adapted for detecting light projected through a crimping die to measure dimensions and configurations of the crimping die. The system stores data representative of desired measurements of the crimping die and compares actual measurements to desired measurements. A set of fixtures are used for positioning the crimping die in the inspection system.

## Claims

### Claim 1

An inspection system for gauging of an indentor mechanism used for crimping contacts onto a wire cable end comprising:
apparatus for positioning the indentor mechanism in a predetermined orientation;
a light source for projecting a light beam through the indentor mechanism;
a light sensor panel for detecting an image of the indentor mechanism resulting from projection of the light beam therethrough; and
apparatus for comparing the dimensions of selected elements in the indentor mechanism to predetermined dimensions of an acceptable configuration of the selected elements for gauging the condition of the elements.

### Claim 2

A system for automated inspection of a crimping die used in a crimping tool for crimping contacts onto a wire cable end comprising:
an inspection system having a light projector and a light sensor adapted for detecting a precise pattern of light projected through a crimping die and for providing precise measure of dimensions and configurations of the crimping die;
a computer database associated with the inspection system for storing data representative of desired measurements of the crimping die;
a computer system operatively coupled to the inspection system and the computer database and programmed to compare measurements from the inspection system with the desired measurements from the database and for providing a visual indication of the fit of the measured dimensions and configuration of the crimping die to the stored desired measurements; and
a set of fixtures adapted for use with the inspection system for positioning the crimping die in a predetermined location and orientation in the inspection system.
