I got the charging head networkLISENA 2m long cable launched by Lishen Technology240WWoven USB-C data line, the body of this data line adopts two-color knitting process, the terminal adopts bright plastic shell, and is printed withLISENBrand.This fast charging cable supports PD3.1240WCharging power, and downward compatible with 100W fast charging, to meet the needs of notebook and mobile phone charging.Here is the Lisen Technology240WTake a look at the internal materials and workmanship when disassembling the data line.
LISEN240WThe braided data line is bound by two rubber rings after being wound for several times, giving the first impression that it is very long enough to meet the needs of most scenarios.
The wire ends at both ends of the cable adopt black bright plastic shell, which is also printed withLISENBrand.
Close up of USB-C male head, internal non full PIN design.
Like Apple woven fast charging cable, the body and head of this data cable are also designed without tail.
The wire material is mainly black, but the knitted coat is made of gray and black two-color lines, which is more recognizable than the conventional black lines and avoids aesthetic fatigue.
The measured length of LISEN braided data line is about 202.5cm.
The diameter of wire body is 3.75mm.
The overall weight is about 48g.
Using ChargeLAB POWER-Z KM003C, it is measured that the cable is equipped with an E-Marker chip, the data transmission capacity is USB 2.0, the power transmission capacity is 50V5A, and supports USB PD3.1 240W fast charging.
In terms of voltage drop test, the test data results of 15 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 0.93V of 20V5A and 28V5A, and the gear with the lowest difference is 0.18V of 5V1A, 9V1A, 12V1A, 15V1A, 20V1A, 48V1A.
Disassembly of LISEN 240W braided data cable
After seeing the appearance, length and test of this kind of braided data cable of Lisen Technology, we will disassemble it to see the internal materials of this data cable.
First, cut the outer plastic shell of the USB-C terminal.
Fill and inject glue inside the plastic shell.
Clean the filling and glue injection on the terminal surface and continue to observe.
One side of the small terminal board is welded with positive and negative wire cores, CC wire cores and USB2.0 data lines.
The other side of the small terminal board is welded with the E-Marker chip.
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.
Continue to cut the outer plastic shell of the USB-C terminal at the other end and disassemble the terminal at the other end.
Fill and inject glue inside the plastic shell.
Clean the glue injection on the small terminal board.
One side of the small terminal board is welded with positive and negative wire cores, CC wire cores and USB2.0 data lines.
There is no E-Marker chip welded on the other side of the small board.
Cut the data wire to observe the section. The outermost layer is the braided sheath, the inner core is the white sheath, the thickened red core is the positive power core, the blue core is the CC core, the white green core is the USB2.0 core, and the negative pole is the thickened black core.
Inside the braid is a white cable sheath.
Close up of power core and data core inside the cable.
Cut out a section of cable and disassemble it, which is in turn braided sheath, plastic sheath, power cable core, data cable core, etc. Next, we will start to introduce the core design inside the cable in detail.
A close-up of the positive red power wire core, with multiple strands of copper wire inside and anti pulling wire inside.
The blue CC line is internally provided with a stay wire.
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.
A close-up of the black power core of the negative pole, with multiple strands of copper wire inside and anti pulling wire inside.
Take a look at all of them and have a family photo.
Disassembly summary of charging head network
LISEN LISEN Technology's braided data cable supports 240W charging power. The cable uses a braided body, and the terminal uses a bright plastic shell, which is beautiful and fashionable.The plastic terminal is marked with LISEN Lisen brand, and the length of the data cable is 2 meters. It supports USB2.0 data transmission and is suitable for laptop, mobile phone and high-power mobile power charging.
The charging head network learned from the disassembly that the USB-C data line terminal of Lisen Technology adopts injection molding process, and the inside of the shell is filled with glue to increase strength.The cable terminal adopts the British Chips IP2133H E-Marker chip for the cable transmission capacity marking. The peripheral components of the chip are simple, with comprehensive functions, and can be adapted to various USB-C cables of different powers and types.
