Turret Connectors are electrical interconnect solutions featuring cylindrical terminals with threaded posts for secure wire attachment. This screw-type connection mechanism allows reliable termination of stranded or solid wires without soldering. Their vibration-resistant design and high current-carrying capacity make them critical components in automotive, industrial, and aerospace systems requiring robust electrical connections.
| Type | Functional Characteristics | Application Examples |
|---|---|---|
| Single-Turret Terminal | Single threaded post with hexagonal drive | Automotive battery connections |
| Double-Turret Terminal | Dual independent threaded posts | Industrial control panels |
| Weatherproof Turret | Sealed housing with IP67 rating | Marine electrical systems |
| High-Temperature Terminal | Rated for 200 C continuous operation | Industrial ovens |
Typical turret connectors consist of: - Conductive core (brass/copper alloy with gold/silver plating) - Insulating body (high-temperature nylon or PBT) - Threaded turret (M3-M8 metric sizes) - Locking mechanism (nylon insert or mechanical lock tab) - Mounting flange (steel with zinc coating)
