Boxwave 3.5mm TRS Male to 3-Pin Screw Terminal Adapter 30cm

Purpose and audience

This adapter converts a 3.5mm TRS stereo male plug to a three-pin screw terminal block. It is intended for installers, hobbyists and technicians who need to connect bare wires to a standard 3.5mm jack without soldering. The 30cm cable provides a short, manageable lead for panel-mount or prototype work.

Sustained behaviour

The screw terminals accept stranded or solid-core wire and clamp securely with a small screwdriver. Because the connection is mechanical rather than soldered, it remains stable under vibration and repeated handling. The balanced TRS wiring maps red to left channel, white to right channel and black to ground, preserving stereo signal integrity over the short length.

Installation and pitfalls

No soldering is required; simply strip each wire, insert it into the labelled terminal and tighten the screw. The main difficulty is the small terminal pitch, which demands fine motor control and a suitably narrow screwdriver. Users who need a longer reach or a different pinout will need a separate cable or custom wiring.
