`2-######`	Current part numbers
`282###-#`	Terminal blocks

Adding New Connector Patterns

•In the manufacturer handler's initializePatterns():

java

registry.addPattern(ComponentType.CONNECTOR, "^NEWCON[0-9].*");
registry.addPattern(ComponentType.CONNECTOR_MANUFACTURER, "^NEWCON[0-9].*");

•Add to getSupportedTypes():

java

types.add(ComponentType.CONNECTOR);
types.add(ComponentType.CONNECTOR_MANUFACTURER);

Similarity Calculation

ConnectorSimilarityCalculator compares:

•Pin count
•Pitch
•Connector type (header, socket, wire-to-board)
•Current rating
•Series family

Key Handler Methods

Extract Series

java

// Returns "61300" from Wurth header
handler.extractSeries("6130014021");

// Returns "43045" from Molex
handler.extractSeries("43045-0212");

Extract Pin Count

Most handlers can extract pin count from MPN for matching purposes.

Connector Handler Registry

There's also a specialized connector handler system in connectors/ package:

•ConnectorHandler - Interface for connector-specific parsing
•ConnectorHandlerRegistry - Registry of connector handlers
•TEConnectorHandler - TE-specific parsing
•WurthHeaderHandler - Wurth header parsing
