Adding New Connector Patterns
- In the manufacturer handler's
initializePatterns():
registry.addPattern(ComponentType.CONNECTOR, "^NEWCON[0-9].*");
registry.addPattern(ComponentType.CONNECTOR_MANUFACTURER, "^NEWCON[0-9].*");
- Add to
getSupportedTypes():
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
// 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 parsingConnectorHandlerRegistry- Registry of connector handlersTEConnectorHandler- TE-specific parsingWurthHeaderHandler- Wurth header parsing
