直流电源适配器接头转换装置设计

Design of DC Power Adapter Connector Conversion Device

在调试地铁电子设备时,规格为5.5-2.1电源适配器输出接头接线方式不方便使用。为便于电源适配器引出导线,设计一款直流电源适配器接头转换装置。详细阐述转换装置组成和功能实现。转换装置可方便地将电源正极和负极引出,实现接头转换,同时具有对电源分线和短路实施保护的功能。

When debugging metro electronic equipment,the wiring mode for output joint of power adapter with the specification of 5.5-2.1 is very inconvenient.In order to facilitate the lead wire of the power adapter with the specifi⁃cation of 5.5-2.1,a DC power adapter conversion device is designed.The components and function of the device is in⁃troduced in detail.The device can easily lead out the positive electrodes and negative electrodes of the power supply for joint conversion,and has the function of the power supply distribution and the short⁃circuit protection.
