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