Modular Connector Keying Concept

For panel-mount-type connectors, keying is usually “built-in” to the connector body, necessitating different part numbers for each key arrangement. This is costly for jobs that require small quantities. This invention was driven to provide a cost savings and to reduce documentation of individual parts.

The keys are removable and configurable in up to 16 combinations. Since the key parts are separate from the connector body, a common design can be used for the plug, receptacle, and key parts. The keying can then be set at the next higher assembly.

This work was done by Scott Ishman, Scott Dukes, and Gary Warnica of Honeywell, and Guy Conrad and Steven Senigla of Lockheed Martin for Johnson Space Center. For further information, contact the JSC Innovation Partnerships Office at (281) 483-3809. MSC-25074-1
