This issue of dismantling brings the USB-C data cable in the Xiaomi 100W car charger set, this charging cable has a black appearance, a length of 1 meter, and the USB-C terminal uses a black glossy plastic shell, and the overall color scheme is black, and the appearance design is very simple. This data cable supports 20V5A 100W charging power and supports USB20 data transmission, can give full play to the output power of the car charger. Let's bring the disassembly of Xiaomi's USB-C data cable, let's take a look at the internal workmanship and materials.
The front of the box is printed with the Xiaomi brand logo, product appearance drawing, name, power and interface logos.
The parameters of the product are printed on the back, in addition to a barcode sticker.
The package contains a car charger, a data cable and an instruction manual.
The data cable is wound and fixed with a rubber ring, and the cable is a classic all-over black design.
The plastic shell of the data cable head is designed with a bright surface and is treated with anti-bending.
Close-up of the inside of the USB-C male connector of the cable, non-full PIN design.
The overall body of the line is smooth and spine.
The total length of the cable is approximately 101cm.
The diameter of the wire body is 38mm。
In addition, the weight of the wire is measured to be about 27g.
Using the ChargerLab Power-Z KM003C, the cable with an E-marker chip is measured, with a power transmission capacity of 20V5A and a data transmission capacity of USB 20。
In terms of pressure drop test, the test data results of 11 gears of the wire rod are shown in the table above.
Drawing a histogram, it can be clearly seen that the gear with the largest voltage drop difference is 0. at 20V5A57V, the lowest difference is 011v。
Finally, use this data cable with a 100W fast charging charger to charge the Apple MacBook Pro, and the measured power is 2008v 4.64a 93.24W, successfully turn on 20V5A PD fast charging.
After reading the appearance, length and actual test of Xiaomi's 100W data cable, let's disassemble it and take a look at the workmanship and materials inside this data cable.
First, use a cutter to cut the black plastic casing of the data cable.
The plastic shell is a metal shell inside, which plays a role in reinforcement.
The other side is the same metal case.
Remove the filled sealant, close-up of the tail harness structure, and use it to fix the data cable.

The metal shell is disassembled, and the inside is reinforced with hard rubber filling.
The glue on the surface of the small plate is removed, and the wire is soldered to the small terminal plate.
The terminal plate is soldered on one side to connect the wires.
A resistor is welded on the other side.
Continue to disassemble the terminal on the other end and use a cutter to cut through the plastic housing.
The inner metal casing is fixed by spot welding.

The metal shell is disassembled, and the inside is reinforced with hard rubber filling.
The terminal plate is soldered on one side to connect the wires.
Remove the filled hard glue and solder an e-marker chip to the small board.
The Yingjixin IP2133H E-Marker chip is soldered on the terminal board, which is a USB Type-C 22 standards and PD31. Standardized USB Type-C cable electronic tag chip, providing a complete E-marker chip solution for USB-C cable. Yingjixin IP2133H has passed USB-IF PD31 Certified, TID: 9513, supports USB-C full-featured cable applications. The chip has an integrated temperature sensor to support real-time cable temperature acquisition.
IP2133H has integrated VCONN diode, integrated RA resistor, chip supports data flashing and flashing protection, and supports data locking. Chip support 27-5.75V operating voltage, 55V withstand voltage support for VCON and CC pins, the chip is available in DFN2*2-6L, DFN2*2-8L and WLCSP-6B packages, suitable for USB-C passive cables, active cables, Thunderbolt 3, Thunderbolt 4, and 240W full-featured cable applications.
Yingjixin IP2133H data information.
Cut the data cable to observe the cross-section, two red thick cores are positive power cores, yellow is VConn cores, blue is CC cores, and white and green are USB20 core, negative electrode transparent thick core.
The outer sheath of the cable is cut and the inside is a braided shielding net.
Underneath the shield is a layer of shielding aluminum foil.
The shielded aluminum foil is filled with power and data cores, and at the same time, it is filled with tensile wires.
The internal cores of the cable are listed in order, including plastic sheath, shielding mesh, shielding aluminum foil, power core, data core, and tensile cable. Let's start with a detailed introduction to the core design inside the cable.
The two red cathode power cores are tinned copper wires with tensile wires inside.
For USB2The data cable for 0 data transmission, the green color is the D+ core, and there is a tensile cable inside.
For USB2The data cable for 0 data transmission, white is the D-core, and there is a tensile cable inside.
The blue CC wire is equipped with a tensile wire inside.
The yellow vconn cable has a tensile cable inside.
The negative power core is made of translucent sheath.

A list of all dismantling and a family photo.
The USB-C cable that comes with the Xiaomi 100W car charger kit is 1 meter long, uses the same black color scheme as the car charger, and supports 100W charging power and USB20 data transmission, which can give full play to the output capacity of the car charger. Paired with a car charger, it can quickly charge Xiaomi mobile phones, and it also supports charging laptops.
Through dismantling, the charging head network learned that Xiaomi's 100W data cable USB-C terminal adopts a plastic shell, and the internal spot welded metal shell is used to fill it with hard rubber to increase strength. The inside of the cable is made of thickened wires, with a braided shield and shielding aluminum foil, and filled with tensile wires to increase strength. The use of Yingjixin IP2133H E-Marker chip for cable transmission capability marking, the peripheral components of the chip are simplified, the functions are comprehensive, and it is suitable for different power and various types of USB-C cables.
