PC connection terminals are the metal pins inside the connectors we use every day. Connectors are usually described by the number of pins they contain – those are called terminals and come in several sizes and shapes. PC terminals are installed by crimping, a process that bends part of the terminal and clamps it to the wire and insulation at the same time. This ensures a good electrical connection at the wire and a good strong physical connection at the insulation. Terminals are offered in many different shapes, with some shapes offered to fit different wire sizes. TITAN RIG has genuine Molex brand Mini Fit Jr terminals for ATX power connections as well as terminals from MOD-ONE and Phobya for fan and SATA connections.
