描述
概述
A female DC barrel socket on a factory-fitted cable, intended for inline power runs rather than board mounting. It comes in 5.5 x 2.1 mm and 5.5 x 2.5 mm barrel sizes, and in 2A and 10A high-current classes.
規格
- Barrel sizes: 5.5 x 2.1 mm, 5.5 x 2.5 mm
- Current class: 2A standard, 10A high current
- Gender: female socket, accepts a male plug
- Termination: pre-wired cable leads, inline jack
- Models: JQ-292/292A/293/293-1 and JQ-301/302/303, in 5521 and 5525 suffixes
目的
A fixed adapter plug rarely suits a repaired or custom harness, so this socket splices in where the original inlet was. The 10A part exists for loads that would run a 2A jack hot.
應用領域
- CCTV camera and DVR power tails
- 12V LED strip and lighting runs
- Router and modem adapter leads
- 修復鬆動的設備入口
- 汽車配件插件接線
如何使用
- Check the device current against the jack class.
- Match plug size: 5521 takes 5.5 x 2.1 mm, 5525 takes 5.5 x 2.5 mm.
- Tin the leads, splice the joints, insulate each conductor.
- Caution: a 2A socket on a 10A circuit overheats at the contacts.
- Buzz out continuity and polarity before plugging in.
