preface
Recently Dell has launched a variety of displays that support USB-C interface, not only support USB-C data expansion, but also support USB-C connection displays, which are very friendly to newly launched notebooks and mobile phones, can connect notebooks for video output on a line, and power the display, which is greatly convenient to use.
The picture shows a schematic of Dell's USB-C-enabled monitor connection, a notebook connected to a monitor, charging while the video is transmitted. The display has a USB HUB that can be connected to other peripherals such as mice, keyboards, headphones, etc. The display supports USB-C video input, which is not only suitable for gaming, but also very convenient for office.
The charging head network disassembled the USB-C data cable that came with a Dell monitor to see how the structure and material of the USB-C data cable that came with the original monitor were.
The original Dell monitor data cable is out of the box
The data cable is a common black color, which is more resistant to dirt and durable.
The cable head is elongated, the shell is frosted for easy insertion and removal, and there are two small round holes at both ends.
USB-C male close-up, full PIN design.
The cable body is labeled, and from the Type C Gen2 5A words on the top, it can be seen that the cable supports the USB3.2 Gen2 (10Gbps) data transmission standard, as well as the high current that can pass 5A.
The overall thread body is smooth and burr-free, and the flexibility is also good.
The cable measured using the ChargerLAB POWER-Z KM002C has an E-Marker chip and supports 20V5A 100W PD fast charging.
The diameter of the measured wire body is about 5.23mm.
The length is approximately 103cm.
Detach the original Dell monitor cable
The data cable connector is wrapped in soft plastic injection molding, which has a good hand feel. The interior is made of steel sleeve spot welding, which is very strong and not easy to damage.
The plug is filled with hard glue insulation and fixed for more durability.
The steel sleeve is fixed to the plug by spot welding to become a whole, and it is resistant to bending and bending.
The shielding mesh is fastened with a steel sleeve to prevent loosening.
The steel sleeve is disassembled, and the terminal PCB and the steel sleeve are fixed with translucent hard glue filling.
The other side is the same structure.
Clean up the hard glue on the terminal PCB, which has an E-Marker chip on it.
The corresponding data core is welded on the back.
Close-up of the E-Marker chip on the front of the small board, screen printed 621 48B, in A CSP package, with only one capacitor on the outer components.
Continue to disassemble the plug at the other end, the plug is also coated with steel sleeves, and the interior is filled with hard plastic reinforcement.
The other side is also reinforced by a hard glue filling.
Remove the hard glue on the PCB, and there are no soldered E-Marker chips on the terminal PCB.
The corresponding data core is welded on the back.
Disassemble the connector and start disassembling the cable below. Underneath the outer skin of the cable is a shield and an internal core.
Underneath the outer skin is a woven shielding mesh, which is used as a ground wire.
Inside the shielding mesh is a shielded aluminum foil that tightly wraps the cable core.
The cable core is also shielded with different colors of shielding layers.
The data core adopts five sets of shielded wires of yellow, green, red, blue and silver, corresponding to USB3.0 data cable and USB2.0 data cable respectively.
Among them, red, yellow, blue and green are USB3.0 data cable shielding cables, silver is USB2.0 shielding cables, black is the positive power core, and silver shielded wires are used for CC communication purposes.
The shielding wire has a yellow outer layer with a yellow and blue data core inside and a bare wire grounding inside.
The remaining USB 3.0 shield cable is the same design.

The two black wires are positive cores.
For the shielded cable of CC wire and VCONN, the red core is wrapped with aluminum foil shield.
The yellow core is of the same design.
The blue wire core is wrapped with aluminum foil shielding.
The brown wire core is shielded with aluminum foil wrapped around the outside.

All disassembled, let's take a family portrait.
Charging head net disassembly summary
Dell USB-C monitor comes with a data cable length of 1 meter, supports 100W power transfer, supports USB3.0 data transmission, and can connect the monitor to the computer to transmit video signals. It can be used for the notebook to connect the display and charge through the USB-C interface, and can also be used to connect the charger for charging.
The charging head mesh was disassembled and found that Dell's USB-C cable connector has an internal spot welded steel sleeve, hard plastic filling, and is very durable. The data cores are all shielded with an external shielding layer, which can effectively avoid interference. As a first-line PC manufacturer, Dell has introduced solid accessories materials and workmanship to meet the needs of high-intensity use.
