The charging head network got a 100W USB-C data cable launched by Lenovo, this data cable model CC510L, using a fresh mint green color, the length of the data cable is 1 meter, it supports 5A high-current transmission, and it supports USB20 data transfer. The two ends of the data cable are integrated injection molded terminals, and the words thinkplus are printed on both ends, which is very recognizable. The following brings the dismantling of Lenovo's USB-C fast charging data cable, and let's take a look at the internal workmanship and materials.
The data cable is packaged in a transparent plastic bag on the front, which is convenient for offline consumers to understand the real thing, and the product name and Lenovo brand are printed on the front.
The back is printed with product descriptions, cable specifications, and business information.
Close-up of the product parameters, the wire model is CC510L, mint green color, and the length is 15 meters, the data transmission specification is USB20, the charging specification is 100W.
The package includes a data cable and a product warranty card.
Compared with the conventional black and white color cable, the Lenovo ThinkPlus 100W fast charging data cable uses mint green color scheme, and the overall appearance is very small and fresh.
The two-end wire head shell is integrated with the net tail, and the thinkplus brand is printed on the front.

The outer skin of the wire is made of excellent TPE material, and the overall flexibility of the wire body feels good.
The measured length of the data cable is about 1 meter.
The diameter of the wire body is 444mm。
In addition, the overall weight of the cable is about 31g.
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 20V5A62V, the lowest difference is 15 20V1A 011v。
Finally, use this data cable with a flash 140W charger to charge Apple MacBook Pro, and the input power of the notebook interface is measured to be 8781W, successfully turn on 20V5A PD fast charging.
After reading the unboxing and display of Lenovo's data cable, let's disassemble it and take a look at the materials inside the cable.
First, cut the injection molded shell of the USB-C plug and fill the inside of the injection molded shell with white hard plastic to protect the USB-C terminal board.
Close-up of the outer layer of hard protective plastic of the terminal plate, and the USB-C plug housing is spot welded with metal shell reinforcement.
Remove the injection molding on the surface of the terminal plate, and solder the e-marker chip and the positive and negative wires on the front of the board.
USB2 is soldered on the back of the small board0 data cores, CC cores and VCONN cores.
Close-up of the E-Marker chip, using Hynetek Semiconductor's HUSB332. This is the high-voltage electronic tag chip (EMarker) launched by Hynetek, which has passed the USB-IF Association certification, TID number: 875, which has made a series of performance improvements and reliability enhancements for various applications and compatibility feedback from customers in the market. The HUSB332 can be mounted on USB20 cable (5A cable), USB30 cable, USB31 cable, USB32 cables and 40Gbps cables.

Then cut open the injection molded shell at the other end.
The outer layer of the terminal plate is filled with transparent hard protective plastic.
Clean up the injection molding on the surface of the terminal board and solder USB20 data cores, CC cores and VCONN cores.
The positive and negative wires are soldered on the other side of the board, and the pads corresponding to the E-marker chip are not discharged.
Cut the data cable to observe the cross-section, in which the red thick core is the positive power core, the blue is the CC core, the yellow is the VCONN core, and the white and green are USB20 core, negative electrode with black thick core.
The outer sheath of the cable is cut, and the inside is shielded aluminum foil, which tightly wraps the inner core of the cable.
Close-up of the power and data cores inside the cable.
The cables are all disassembled at a glance, in order of plastic sheath, shielding aluminum foil, power core and data core. Let's start with a detailed introduction to the core design inside the cable.
The red cathode power core is made of tinned copper wire with tensile wire inside.
For USB20 transmission data cable, green D+ core with tension cable inside.
The white D-core also has a tensile wire inside.

A list of all dismantling and a family photo.
Lenovo's USB-C data cable is 1 meter long, and the cable is made of mint green TPE skin, which feels good to use. The two ends of the cable are injection molded terminals and printed with the word thinkplus, which is very recognizable. The measured cable supports 100W power transmission, which is suitable for laptops, high-power power banks and mobile phone fast charging.
Through the dismantling of the charging head network, it was learned that Lenovo's data cable uses injection molded USB-C terminals, and the inside of the terminals is filled with hard plastic to increase strength. The inside of the cable is made of thickened conductors with shielded aluminum foil, and the cable capability is marked with a Husb332 E-marker chip. The inside of the wire is filled with tensile wire, and the overall workmanship is solid, reliable and durable.
