Usb c cable: What are the four wires in the USB data cable Apphone

The cables you’ll use the most, and therefore need to replace, are micro-USB, USB-C, and Lightning. Usb c cable has a pair of power cords and a pair of twisted-pair signal wires among the 4 core wires. USB Speed Standards. Usb cable: What are the four wires in the USB cable

The four wires of usb c cable are:
black is negative (GND)
Red is the positive pole (VCC), which is the power cord
The green one is the positive terminal of the data line (DATA+)
The white one is the negative pole of the data line (DATA-)

Red is the positive terminal of the power supply, black is the negative terminal of the power supply, green line is the positive terminal of the data transmission, and white line is the negative terminal of the data transmission. The built-in power supply can make the USB interface provide 5v power for USB peripherals. Each USB port can provide 500mA current for peripheral use. I don’t know if you have carefully observed the interface port of the USB cable.

Some high-quality data cables will be wrapped with aluminum foil inside the four wires to resist outside interference, so as to achieve a better data transmission effect. The high-quality data cable is made of pure copper, fast charging speed and fast transmission rate.

Daily mobile phone charging only uses two lines in the data line, that is, a red line (positive) and a black line (negative) responsible for providing charging current.

The green and white data transmission lines are not used in the charging process, and only when the data is transmitted between the computer and the mobile phone, the green and white data transmission lines are used. Since no power supply is involved, these two wires are generally a little thinner than the red and black wires.

Only when we understand clearly what the four cables are, can we easily insert the usb c cable, Usb Data cable purchase, it is recommended to buy high-quality or original wire, internal wire materials are pure copper material, charging speed will be fast. Professional usb cable manufacturer, Apphone is a leading cables group company, Providing usb cable with high quality.

How to maintain the data line?

In daily life, pay attention to keep the data line away from heat sources. If the data line is close to the heat source, the high temperature is easy to cause deformation of the data line, affecting its use function. To replace the data cable, it is recommended to buy a 3C certified brand from official channels.

Picture this: You’re sitting at your desk, engrossed in a project, and suddenly you trip over your laptop’s charging cable. In an instant, your laptop dropped to the floor, giving you a sinking feeling in your stomach. This unfortunate situation was all too common for MacBook users, until Apple introduced a revolutionary solution – MagSafe cable.

MagSafe 2 and MagSafe 3.

MagSafe 1 cable

MagSafe 1 charger debuted on the 2006 MacBook Pro with its magnetic attachment and easy detachment. The first ‌MagSafe‌ port has a square design with five holes that connects to the included port using a magnetic connection. The idea is that if the connector is pulled, it will detach quickly and smoothly without damaging the ‌MagSafe‌ connector or ripping the MacBook Pro off the table or desk. Since its release, it has been an instant hit with MacBook users.

MagSafe 1 cable

Initially, Apple used a T-shaped design that pulled the wires directly out of the machine, and MagSafe charging port later transitioned to an L-shaped design that placed the wires on the side of the computer. The T-shaped design was used from 2006 to 2009, while the L-shaped design was used from 2010 to 2012.

However, as technology advanced and laptops became thinner and lighter, Apple faced a challenge – how to adapt the sleek design of new devices while maintaining the convenience and security of MagSafe. About a decade later, USB-C gradually replaced Apple’s MagSafe. USB-C cables certainly have their advantages, but MacBook Pro owners have never forgotten about MagSafe.

MagSafe 2 cable

Miniaturization led Apple to launch MagSafe 2 in 2012. MagSafe 2 uses a thinner T-shaped connector, allowing Apple to create a slimmer MacBook. The new design fit the thinner Mac computers Apple released that year. While some users prefer the smaller form factor, the Apple ‌MagSafe‌2 connector is not compatible with the original ‌MagSafe‌ connector and requires an adapter.

Apple brought back the T-shaped design with the ‌MagSafe‌2 cable and stuck with it throughout the Apple ‌MagSafe‌’s lifecycle.
