stayAppleAfter the launch of the iPhone 15 series mobile phones with USB-C interface, it was officially announced that the lightning interface, which has been used for 10 years, will become history.In order to keep the USB-C lightning line in the hands of users,AppleA USB-C to lightning converter with a price of 243 yuan was launched simultaneously.
The total length of this converter is about 11cm. One end is a USB-C plug, the other end is a lightning interface socket, and the middle is connected by braided wire.Support charging, data transmission and audio transmission functions.The charging head network is right belowAppleDisassemble the newly launched USB-C lightning converter, and take a look at the internal workmanship and materials of this converter.
Printed on the front of the packing boxApplelogo、Product name and appearance.
The back is printed with the multilingual name of the product, male head and Lightning socket logo at both ends, application scenario diagram, CE certification logo, etc.
The official name of the product is USB-C to lightning converter, and the model is A2868.In addition, the manufacturer, dealer, manufacturing address, contact number and other information are also printed on this side.
The sticker on the other side is printed with compatible iPhone and iPad models equipped with USB-C interface.
The package contains Apple USB-C to lightning converter, warranty card and multilingual instructions.
Apple USB-C to lightning converter is positioned as a conversion function accessory, which is short in design. The wire head shells at both ends are treated with high bright surface, and the connecting wire body jacket is woven with wear-resistant and explosion-proof leather.
The internal pin of USB-C male head is gold-plated, and the pin is not full.
There is no tail design at both ends of the connecting wire body.
The housing at the other end has a Lightning socket logo design.

The measured end-to-end length of Apple USB-C to lightning converter is close to 11cm.
The diameter of wire body is 3.59mm.
The size of the product in the hand is intuitive.
In addition, the measured net weight is about 10g.
Using ChargeLAB POWER-Z KM003C, it is measured that there is no E-Marker chip inside the USB-C end of Apple's converter.
The iPhone 15 series of the charging head network has not arrived yet. Here we simply test the charging effect of the down converter with Apple's original Lightning cable for the iPad Pro, and the measured power is 8.8V 2.93A 25.75W.
Charging Apple MacBook Pro, the measured power is 8.34V 2.88A 24W.
Disassembly of Apple USB-C to Lightning Converter
After seeing the unpacking and actual use of this USB-C to lightning converter, we will disassemble it to see the internal structure.
First, cut the plastic shell of the USB-C plug. The internal terminals are reinforced with stainless steel sleeves. There are dense laser welding spots at the corresponding positions of the cable and plug, which are used to fix the tail harness sleeve and the USB-C plug.
Continue to cut and cut the internal stainless steel sleeve. The internal USB-C terminal is connected by welding a small plate, and the terminal is filled and fixed with glue.
The front of the small USB-C terminal board is at a glance. The front of the small board is welded with positive and negative electrode wires and data lines, and the solder joints are glued and reinforced.
There is no welding wire or welding element on the back of the small board.
Continue to disassemble the lightning socket. First, use the cutter to cut the white plastic shell, and the interior is a stainless steel shell.
Interior view of plastic housing.
The shell of the corresponding lightning socket is fixed with soft rubber material to improve the feel of use.
Continue to disassemble the internal laser welded stainless steel shell, disassemble the lightning socket shell, use the soft and hard board process inside, and connect the two PCBs through the soft board.
Close up of PCB inside the shell, and the components are sealed with glue as a whole.
The small board on this side is welded with lightning terminals, and the components are covered with glue.
The welding part of the conductor is coated with glue for reinforcement.
The components on the back of the small board are also covered with glue.
Another PCB element is covered with glue for protection and insulation.
There are no welding elements on the other side.
Next, disassemble the cable. There are red, yellow, blue and green cores inside the cable.
Below the skin is a layer of winding shielding mesh.
The internal wire core is a rotary winding structure, which can better eliminate stress and make the cable more flexible.
All the cables are disassembled for a glance, which are in turn woven jacket, plastic sheath, metal shielding mesh, data cable core, etc., and then the core design inside the cable will be introduced in detail.
The two positive power wire cores are tinned copper wires.

Disassembly summary of charging head network
Apple's latest USB-C to lightning converter completely announced that the lightning interface, which has been used for ten years, will come to the end of its life.Although there are numerous lightning interface devices, the USB-C interface has already become a mainstream interface and has been accepted by consumers.Apple's USB-C to lightning converter supports fast charging, data transmission and audio transmission functions, and supports the use of devices connected to other lightning interfaces.
It is learned from the disassembly of the charging head network that this converter continues Apple's traditional workmanship and quality. Under the plastic shell at both ends, the stainless steel shell and the metal shell of the plug are welded and fixed, and filled with glue to enhance the mechanical strength.PCB with soft and hard board process is set at the lightning interface, and all components are covered with hard glue for protection. It can be said that the workmanship is still apple like.
