What this dismantling brings ismillet100WThe USB-C data cable in the car charging package is black in appearance and 1m in length. The USB-C terminal is covered with black bright plastic shell, and the overall color is black. The appearance design is very simple.The measured data line supports 20V5A100WCharging power, supporting USB2.0 data transmission, can fully start the car charging output power.Here comesmilletTake a look at the internal workmanship and materials when disassembling this USB-C data cable.
Printed on the front of the packing boxmilletBrand logo, product appearance, name, power and interface identification.
The parameter information of the product is printed on the back, and the barcode sticker is also pasted.
The package contains the car charger, data cable and user manual.
The data line is fixed by rubber ring after winding, and the wire material is a classic black design.
The plastic shell of the data line head is designed with a bright surface, and is subject to anti bending treatment.
Internal close-up of USB-C male head of wire material, with non full PIN design.
The whole thread body is smooth without burrs.
The total length of the cable is about 101cm.
The diameter of wire body is 3.8mm.
In addition, the measured wire weight is about 27g.
Using ChargeLAB POWER-Z KM003C, it is measured that the cable is equipped with an E-Marker chip, with power transmission capacity of 20V5A and data transmission capacity of USB 2.0.
In terms of voltage drop test, the test data results of wire rod at 11 gears are shown in the table above.
The histogram is drawn. It can be clearly seen that the gear with the largest difference in pressure drop is 0.57V of 20V5A, and the gear with the lowest difference is 0.11V of 9/12/15V1A.
Finally, use this data cable100WThe fast charging charger charged Apple MacBook Pro, and the measured power was 20.08V 4.64A 93.24W. The 20V5A PD fast charging was successfully started.
After seeing the appearance, length and actual test of Xiaomi's 100W data cable, we will take a look at its internal workmanship and materials.
First, use a cutter to cut the black plastic shell of the data line.
The inside of the plastic shell is a metal shell for reinforcement.
The other side is also the same metal shell.
Remove the filled sealant, and make a close-up of the wire tail harness structure, which is used to fix the data line.
Close up of spot weld between metal shell and USB-C terminal.
Dismantle the metal shell, and fill and reinforce the interior with hard glue.
Remove the glue on the surface of the small board, and connect the wire to the terminal board by welding.
One side of the small terminal board is welded to connect wires.
Weld a resistance on the other side.
Continue to disassemble the terminal at the other end and cut the plastic housing with a cutter.
The internal metal shell is fixed by spot welding.
Close up of spot weld between metal shell and USB-C terminal.
Close up of wire tail harness structure.
Dismantle the metal shell, and fill and reinforce the interior with hard glue.
One side of the small terminal board is welded to connect wires.
Clean the filled hard glue and weld an E-Marker chip on the small board.
Yingji core IP2133H E-Marker chip welded on the terminal board is a USB Type-C cable electronic label chip that supports USB Type-C 2.2 standard and PD3.1 specification, providing a complete E-Marker chip solution for USB-C cable.Yingjixin IP2133H has passed the USB-IF PD3.1 certification, TID: 9513, supporting USB-C full function cable applications.Integrated temperature sensor inside the chip supports real-time cable temperature acquisition.
IP2133H is internally integrated with VCONN diode and Ra resistor. The chip supports data burning and write protection, and supports data locking.The chip supports 2.7-5.75V working voltage, VCONN and CC pins support 55V withstand voltage, and the chip provides DFN2 * 2-6L, DFN2 * 2-8L and WLCSP-6B packaging, which is suitable for USB-C passive line, active line, lightning 3, lightning 4, and 240W full function cable applications.
Yingjixin IP2133H data information.
Cut the data line and observe the section. Two red thick cores are positive power cores, yellow is VCONN core, blue is CC core, white green is USB2.0 core, and negative is transparent thick core.
Cut the outer skin of the cable, and the inside is braided shielding mesh.
Below the screen is a layer of shielding aluminum foil.
The interior of the shielding aluminum foil is the power wire core and data wire core, and the interior is also filled with anti pull wire.
The list of cable cores inside the cable includes plastic sheath, shielding mesh, shielding aluminum foil, power core, data core and tension wire.Now we will begin to introduce the design of the cable core in detail.
The two red positive power wire cores are tinned copper wires with anti pull wires inside.
The data line used for USB2.0 data transmission is D+wire core in green, with anti pull wire inside.
The data line used for USB2.0 data transmission is D-core in white, with anti pull wire inside.
The blue CC line is internally provided with a stay wire.
The yellow VCONN cable is equipped with anti pull wire inside.
The negative pole power core adopts a translucent sheath.
Close up of anti stay wire filled inside the cable.
Take a look at all of them and have a family photo.
Disassembly summary of charging head network
The USB-C data cable attached to the Xiaomi 100W car charger set is 1 meter long. It uses the same black color as the car charger, supports 100W charging power and USB2.0 data transmission, and can give full play to the output capacity of the car charger.With the car charger, it can quickly charge the Xiaomi mobile phone and also support charging the laptop.
The charging head network learned through disassembly that the USB-C terminal of Xiaomi's 100W data line uses a plastic shell, and the internal spot welding metal shell is filled with hard glue to increase strength.Thickened wires are used inside the cable, and woven shielding mesh and shielding aluminum foil are set, and anti stay wire is filled to increase strength.Yingjixin IP2133H E-Marker chip is used to mark the cable transmission capacity. The peripheral components of the chip are simple and have comprehensive functions. It is suitable for USB-C cables of different powers and types.
