USB Type革新,探索新型接口的未来趋势与挑战-HIS时尚网

Okay, "USB Type" usually refers to the "physical connector shape and size" of a USB port or cable. There are several major types currently in use:
1. "USB Type-A:" "Description:" The most common rectangular connector, recognizable by its flat top edge. This is what you typically find on computers, laptops, tablets, and many peripherals. "Usage:" Primarily for host devices (like computers) connecting to peripheral devices (like keyboards, mice, printers, external drives). It's generally not reversible (you can only plug it in one way).
2. "USB Type-C (USB-C):" "Description:" A newer, smaller, and more versatile connector with a symmetrical,梯形 (ladder-shaped or trapezoidal) design. It's much smaller than Type-A and reversible (can be plugged in either way up). "Usage:" Found on modern smartphones, tablets, laptops, desktop computers, game consoles, and various peripherals. It supports higher power delivery and faster data transfer rates than older USB standards. It can also supply power to charge devices.
3. "USB Type-B:" "Description:" A square connector, often found on larger peripherals like printers, external hard drives, and some monitors (less common now). "Usage:" Typically used as a device connector, plugging into a host's Type

一、前言

那么一根Type-c线材能过2A电流肯定不够用了，像VIVO、一加、华为等厂商已经将数据线电流设计到5A。之前跟大家分享过2A电流下的内阻和压降测试，大部分线材的压降都还能接受。那么，到了3A电流，内阻大的线材压降就不堪入目了，甚至可以讲大部分线材根本过不了3A电流。小电流时代，内阻大点影响倒不是很大；大电流时代，内阻一定要小！这次给大家带来3A电流下的若干TYPE-C线材的内阻和压降测试，帮大家找出支持3A及以上电流的数据线，希望大家喜欢。
