Five-pack solderless audio adapter

This Boxwave adapter converts a 3.5 mm 4-pole TRRS female jack to a 4-pin screw terminal block in a compact black housing measuring 3.7 cm by 2.3 cm. The pack of five suits installers who need multiple solderless connections for microphone, headphone or AV cables. No soldering is required; only a screwdriver and wire stripper are needed to terminate cables quickly.

AWG 26-16 wire range

The screw terminals accept conductors from AWG 26 to 16, which determines whether your existing cable fits without modification. If the wire gauge falls outside this range, a different termination method or adapter will be necessary.

Sustained connection reliability

The screw-terminal design maintains a secure mechanical bond that resists vibration and temperature cycling better than friction-fit plugs. This makes the adapter suitable for permanent installations where cables remain connected for long periods.

Questions about this item

Will the 3.5 mm TRRS jack carry both stereo audio and a microphone signal through the adapter?

Yes, the 4‑pole 3.5 mm female jack accepts a standard TRRS plug so left, right, ground and mic contacts all pass through to the screw terminals.

What wire gauges can the screw terminals accept?

The terminals are rated for AWG 26‑16 solid or stranded wire, so typical headset and microphone cables fit without soldering.

How much space does each adapter need inside an enclosure?

Each unit measures 3.7 cm long by 2.3 cm wide, so allow at least that footprint plus room for a small screwdriver to tighten the terminals.
