1.8 meters, lightning 3, 100W fast charge, I heard that as long as 70 yuan? Disassemble the Dell full-featured cable

preface

The Raiden 3 data cable has a super high transmission rate, and many high-end computers will be equipped with the Thunderbolt 3 interface for high-speed transmission of data and video expansion. Because of the high specifications of Raiden 3, the price of 2-meter-long cables is usually close to 1,000 yuan, which discourages many consumers.

Charging head network got a Dell Dell full-featured data cable, the length of the line is 1.8 meters, although its appearance is not good, but the actual measurement supports Lightning 3 high-speed transmission, and supports 100W fast charging, the following will be disassembled on this line to see how the interior is designed.

Dell 1.8m full-featured line out of the box

The cable obtained by the charging head net is bulk and is covered with plastic film, which is very simple.

The overall weight of the cable is about 82g.

The wires at both ends are relatively long, the shell is frosted for easy insertion and removal, and both are designed with three small circular grooves, in addition to the anti-bending design.

USB-C male close-up, full PIN design.

Attached is a simple 24PIN instruction for USB-C.

The measured wire body diameter is 5.33mm, which is already thicker than most data lines on the market.

The length is 1.8 meters.

Using the ChargerLAB POWER-Z KM002C, this is a passive Lightning 3 data cable that supports a transmission bandwidth of 40 Gbps and a power transmission capacity of 100W.

Using a flash pole 140W Gallium Nitride charger with cables to charge the MacBook Pro 16 2201 with a power of 20.47V 4.65A 95.17W.

To test whether the cable supports data transfer function, connect the notebook computer and the Acacias USB4 hard disk box at both ends of the cable, which is loaded with Samsung 970EVO SSD.

The actual measured write speed is about 1462.1MB/s, and the read speed is about 2853.6MB/s, which is basically equivalent to the transmission specification of Raiden 3. The high data transfer speed means that large files can be transferred in seconds, which can effectively improve work efficiency.

Dell 1.8m full-featured cable disassembly

Dell full-featured data cable plug using soft plastic injection molding, feel very good, injection molded inside is a steel sleeve, spot welded to the USB-C plug, high strength is not easy to break.

The inside of the plug is fixed by a steel sleeve, and the internal filling is reinforced with hard plastic and solid workmanship.

The steel sleeve on the other side is also spot welded to the USB-C terminal for fixing, and the steel sleeve extends out of the line card to fix the shielding mesh.

The wire card holds the steel sleeve and the data wire core.

The other side can be seen to be fixed by stamping.

The steel sleeve is removed and the plug is filled with translucent hard plastic supports.

The data cable is welded on one side of the shielded wire and the power cord.

The back side is welded with shielded wires and USB data cables, and the E-Marker chip is not soldered on the terminals, and the other end is continued to be disassembled.

The other end of the data cable is the same design, which will not be introduced here. The E-Marker chip can be seen on the terminals on the other end.

The other side of the terminal is the same design.

Close-up of the E-Marker chip on the terminal board, silk screen 621 73B, in a CSP package, with only one capacitor on the outer components.

Continue to remove the male shell, the dismantling method is not very high-minded, in the process some of the stitches fell off, in addition to a little tin.

Disassemble the plugs at both ends and start disassembling the cable below. Underneath the outer skin of the cable is a shield and an internal core.

Attach the Wikipedia description of the color of the USB-C cable, of course, but also on a case-by-case basis.

Underneath the outer skin is a woven shielding mesh.

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 shielded aluminum foil.

The shielding mesh and shielding aluminum foil are removed, exposing the inner core of the data cable.

Among them, the red, yellow, blue and green shielding cable is the Thunderbolt 3 data cable, the silver is the USB2.0 shielding cable, the black is the positive power core, the silver shielding cable is used for CC communication, and there are three anti-tensile wires inside.

Raiden 3 is wrapped in blue shielded aluminum foil, with a yellow-blue wire inside for differential routing and a bare wire for grounding.

The green shielded wire is the same design.

There is no ground wire inside the silver shield cable, and the white and green cable is used for USB 2.0 data transfer.

Two cathode cables close-up with a black skin.

The cable corresponding to the VBUS and CC functions is also shielded with aluminum foil, and the silver shielded aluminum foil has a blue core inside.

The silver shielded aluminum foil has a red core inside.

The silver shielded aluminum foil has a yellow core inside.

The silver shielded aluminum foil has a brown core inside.

Three anti-brush close-ups in the cable.

All disassembled, let's take a family portrait.

Charging head net disassembly summary

Dell's full-featured data cable is 1.8 meters long, supports 20V 5A 100W power transmission, and can be quickly charged to external monitors, storage devices and laptops to meet the needs of longer-distance lightning equipment. The plug at both ends of the cable is anti-bending treatment, and the plug shell is injection molded with soft plastic, which makes it feel good to use.

Through disassembling, the charging head network found that Dell's 1.8-meter full-featured data cable connector has a spot welded steel sleeve inside, hard plastic filling, and is very durable. The data wire core is covered with aluminum foil shielding layer, and there is also a shielding mesh under the outer skin connected with the steel sleeve, which is fully shielded and 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.
