Glossary of Terms:
- Adapters: To interconnect two connectors already attached to wires.
- Block Fork: Same strength as a fork, but designed for terminal blocks with flat sides against the barrier.
- Butt Connector: Uses chamfered barrel ends for fast wire insertion from both ends and a built-in wire stop. Must be crimped at both ends.
- Closed-End Connector: Used for pigtailing two or more wires.
- Fork: Allows rapid connection of wire, typically used on free-standing studs.
- Locking Fork: Spring-like tongue locks onto the stud, even if the mounting screw is loose.
- Parallel Connector: Similar to butt connectors but with overlapped wires and a single crimp in the center.
- Pin Terminal: For installation in compression blocks, commonly used in Europe for terminating stranded wire.
- Quick Connect (Disconnect): Attached by the female part's tongue slipping over the male tab, allowing easy and quick disconnection.
- Ring Tongue: Standard tongue style, offering the safest and most reliable connection.
- Tab: Uses a mounting hole for a rivet or screw.
- Tap: Requires no wire stripping; wire is laid in the connector and crimped.
