Description

Overview

A male DC barrel plug with a solder-cup tail, for replacing a damaged plug or building a new lead. Seven sizes run from 2.5 x 0.7 mm to 5.5 x 2.5 mm, straight or as a 90-degree elbow.

Specifications

  • Male DC power plug, solder termination
  • Barrel sizes: 2.5 x 0.7, 3.5 x 1.1, 3.5 x 1.35, 4.0 x 1.7, 4.8 x 1.7, 5.5 x 2.1, 5.5 x 2.5 mm
  • Size format: outer barrel x centre pin
  • Bodies: straight or 90-degree elbow

Purpose

Routers, laptop supplies and pedals share one barrel idea at different sizes, so a split plug can scrap a whole adapter. Cut it off and solder a match back on; the elbow body suits a jack close to a wall.

Applications

  • Laptop power supply lead repair
  • Custom DC lead for a router or switch
  • Right-angle feed to a wall camera
  • DC tails for LED strip or CCTV

How to Use

  1. Measure the old plug: outer bore and centre pin, then order that size.
  2. Slide heat-shrink onto the cable before soldering.
  3. Check the polarity the device expects on its label; do not assume centre-positive.
  4. Tin wire and cup, join them, and meter for a bridge to the outer shell.
  5. Stay within the current your wire and supply carry; the plug takes the full load.
