name: connector description: Use when working with connector components - headers, sockets, wire-to-board, board-to-board connectors. Includes adding patterns, parsing connector MPNs, extracting pin count, pitch, and series information.

Adding New Connector Patterns

1. In the manufacturer handler's initializePatterns():

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

1. 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 parsing
• ConnectorHandlerRegistry - Registry of connector handlers
• TEConnectorHandler - TE-specific parsing
• WurthHeaderHandler - Wurth header parsing
