전원 공급 장치의 올바른 플러그를 어떻게 결정합니까? (전원 어댑터, 전원 공급 장치, AC 어댑터, 노트북 어댑터) 또는 전원 공급 장치 플러그가 장치에 맞는지 선택하세요.?
목차
전원 플러그가 왜 다른가요??
시중에는 다양한 전원 공급 장치가 나와 있습니다., although they have identical data and in some cases also have the same model designation, still differ in some cases in terms of the power supply plug size.
How do you know the power supply plug fit into your device?
If you have found a suitable power supply and all values match the polarity, how do you know whether the suitable plug-in of the right size is mounted on this power supply and fits into your device?
Polarity: An important detail, incorrect polarity, can make the effects device unusable. Most effect devices need an internal negative pole, also known as a “negative tip.” The polarity is also often shown on the corresponding devices such as notebook, USB 전원 전압 레벨 및 커넥터의 폭넓은 수용으로 인해 전원 전용 애플리케이션에서도 널리 사용됨, directly at the input of the connector or on the device name, 등.
You have already landed a hit when the plug size of the power supply unit is specified in the item description. But all of this will only help you if you also know which connector size you need.
The easiest way, in this case, is you still have your old original power supply and can measure the shaft diameter (ㅏ) with a ruler or, even better, with a caliper.
How to confirm the power supply plug size if you miss the original power adapter?
If the original power adapter is no longer available, you still have a certain number of other power adapters or chargers. LED 헤드 램프, the telephone, modem, router, 더 무거운 게이지 케이블, 더 무거운 게이지 케이블, old cassette recorder, mp-3 player, toys, cordless screwdriver, 등.
Try out which of these power adapters the plug fits into your device. (물론이야, without plugging it into the socket, this is only about the power adapter plug size) Once you have found a suitable connector, measure the shaft diameter.
Most standard power adapter plug size
The most common DC connector sizes are given here as a guide. Please note that you always measure a touch less than the standard size.
2.4×0.75mm
3.5×1.3mm
4×1.7mm
4.75×1.7mm
5.5×2.1mm
5.5×2.5mm
6.35×3.0mm
The first number indicates the size of the shaft (picture-red), and the second number the diameter of the hole in the middle of the power adapter plug (picture-blue).
있다 2 standard sizes of these power supply plugs with a shaft diameter of 5.5mm. One with a hole in the middle of 2.1mm and the other with a hole of 2.5mm.
This can only be measured with a caliper. If you don’t have this tool at hand, the ballpoint pen trick will help:
A conventional ballpoint pen refill has a diameter of 2.5mm. So take a ballpoint pen and insert its lead tip into the front of the power supply plug (only with 5.5mm plugs). If only a piece of the lead tip fits into the plughole at the front, its diameter is 2.1mm. If you can insert the mine deeper, its diameter is 2.5mm.
The barrel connector sizes listed above are most often found on plug-in power supplies, which is not to say that there are no power supplies with other plugs.
Several barrel connectors have an inner pin instead of a hole in the middle. These are used, among other things, for notebook power supplies, 더 무거운 게이지 케이블, and printer power supplies.
This picture shows that the power supply connector with inner pin can also be recognized and differentiated with inner and outer diameter.
Conclusion: Measure the inner and outer diameter, check the polarity, amperes, and watts, and you already know which power supply you need …
