Connectors Overview

Overview​

Proper connectors are essential for reliable electrical connections on FRC robots. Different types of connectors are used for different applications, from high-current power connections to low-current signal connections.

important

Whenever connecting wires, make sure to do the pull test to assure the wires are properly connected.

Connector Selection Guidelines​

Power Connections (High Current):

  • Use Anderson Powerpoles for removable connections
  • Use ring terminals for permanent bolt connections
  • Always match connector rating to circuit requirements

Signal Connections (Low Current):

  • Use Molex SL connectors for removable signal connections
  • Use ferrules for screw and push terminal connections

Connector Quick Reference​

Anderson Powerpoles​

Anderson Powerpoles are the standard connector for power distribution in FRC robots. They provide reliable, high-current connections that can be easily assembled and disassembled.

Applications:

  • Power Wires
  • CAN Wires

Ferrules​

Ferrules are small metal sleeves that are crimped onto the end of stranded wire to provide a solid, reliable connection point for screw and push terminals.

Applications:

  • Any push connector

Ring Terminals​

Ring terminals provide secure connections to bolts, screws, and studs. They are commonly used for ground connections and battery terminals.

Applications:

  • Battery terminal connections
  • Kraken wiring

Molex SL Connectors​

Molex SL connectors are commonly used for CAN bus connections and other low-current signal applications. They provide reliable, removable connections for communication and sensor wires.

Applications:

  • CAN bus connections between devices
  • Sensor signal connections
  • Low-current control connections

WAGO Connectors​

WAGO connectors are lever-actuated wire connectors that provide secure, toolless connections for electrical wiring.

Applications:

  • Quick wire splicing

Push Connectors​

Push connectors (also known as push-in or spring-loaded connectors) are toolless connectors that allow wires to be inserted directly into the terminal without screws or levers. They are commonly found on various electrical devices and provide quick, secure connections.

note

When using push connectors with stranded wire, always use ferrules to ensure a reliable connection and prevent wire strands from spreading.
