# Connector Component Skill Guidance for working with connector components in the lib-electronic-components library. ## Supported Manufacturers & Patterns | Manufacturer | Handler | MPN Patterns | Example | |--------------|---------|--------------|---------| | Wurth | `WurthHandler` | `61########`, `62########` | `6130xx14021` | | Molex | `MolexHandler` | `43###-####`, `39###-####`, `53###-####` | `43045-0212` | | TE Connectivity | `TEHandler` | `1-######`, `2-######`, `282###-#` | `282836-3` | | JST | `JSTHandler` | `PH#`, `EH#`, `XH#`, `ZH#` | `PHR-2` | | Hirose | `HiroseHandler` | `DF#`, `FH#`, `BM#`, `ZX#` | `DF13-2P-1.25DSA` | | Amphenol | `AmphenolHandler` | `10####`, `20####` | `10127716-001 | ## ComponentTypes ```java // Base type ComponentType.CONNECTOR // Manufacturer-specific types ComponentType.CONNECTOR_WURTH ComponentType.CONNECTOR_MOLEX ComponentType.CONNECTOR_TE ComponentType.CONNECTOR_JST ComponentType.CONNECTOR_HIROSE ComponentType.CONNECTOR_AMPHENOL ComponentType.CONNECTOR_HARWIN ``` ## Wurth Connectors ### MPN Structure ``` 61 300 14 021 1 │ │ │ │ │ │ │ │ │ └── Variant (plating, orientation) │ │ │ └────── Pitch code (021=2.00mm, 254=2.54mm) │ │ └───────── Pin count (14 pins) │ └───────────── Series (300=WR-PHD) └──────────────── Product family (61=Headers) ``` ### Series Codes | Prefix | Series | Description | |--------|--------|-------------| | 61 | Pin Headers | Male headers | | 62 | Socket Headers | Female headers | | 613 | WR-PHD | Pin Header Double Row | | 614 | WR-BHD | Box Header | | 615 | WR-TBL | Terminal Blocks | ## Molex Connectors ### Series & Families | Series | Family | Pitch | Current | |--------|--------|-------|---------| | 43045 | Micro-Fit 3.0 | 3.00mm | 5A | | 39281 | Mini-Fit Jr. | 4.20mm | 9A | | 53261 | PicoBlade | 1.25mm | 1A | | 22057 | KK 254 | 2.54mm | 3A | | 51021 | PicoClasp | 1.00mm | 1A | | 51047 | Nano-Fit | 2.50mm | 3.5A | ### MPN Structure ``` 43045 - 0212 │ │ │ └── Position/variant (02=2 circuits, 12=vertical) └────────── Series (Micro-Fit 3.0) ``` ## JST Connectors ### Series | Series | Pitch | Description | |--------|-------|-------------| | PH | 2.00mm | Wire-to-board | | XH | 2.50mm | Wire-to-board | | EH | 2.50mm | Wire-to-board | | ZH | 1.50mm | Wire-to-board | | SM | 2.50mm | Wire-to-wire | | PA | 2.00mm | High density | ### MPN Pattern ``` PHR-2 │ │ │ └── Pin count └───── Series (PH = 2.0mm pitch) R = Receptacle housing ``` ## TE Connectivity Connectors ### MPN Patterns | Pattern | Description | |---------|-------------| | `1-######` | Legacy part numbers | | `2-######` | Current part numbers | | `282###-#` | Terminal blocks | ## Adding New Connector Patterns 1. In the manufacturer handler's `initializePatterns()`: ```java registry.addPattern(ComponentType.CONNECTOR, "^NEWCON[0-9].*"); registry.addPattern(ComponentType.CONNECTOR_MANUFACTURER, "^NEWCON[0-9].*"); ``` 2. 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 --- ## Learnings & Quirks <!-- Record component-specific discoveries, edge cases, and quirks here -->
