preface:

On March 31, 2015, at the new product communication meeting of Xiaomi's 5th Anniversary Rice Noodle Festival, Xiaomi released five new products at one go: Xiaomi NOTE Goddess Edition, Hongmi 2A Mobile Phone, Xiaomi Plug in Board, Xiaomi TV and Xiaomi Scale. On the day of the Rice Noodle Festival, the patch panels were out of stock, and the demand exceeded the supply, which shows how much users like this product!

The patch panel is a necessary household product for every household, and its brands are countless. For example, the Bull safe socket we know is deeply rooted in the hearts of the people. Xiaomi unexpectedly launched the patch panel at this time. I thought that when Xiaomi launched various smart products in succession, this patch panel must also be an "intelligent" product, It will be a member of Xiaomi's intelligent ecosystem, but it is not. What is the difference between this patch board and how can it be robbed by so many people? Today, I will reveal the secret for you.

Unpacking:

Xiaomi cable tray, packaging box and Xiaomi mobile phone are different from other products. They are not wrapped in kraft paper, but like most of its products, white packaging boxes are used. There is a logo in the middle of the packaging box, which is the consistent style of Xiaomi.

The opening is also sealed by a round sticker with a meter character on it, indicating that it is one of Xiaomi's products

The back of millet flat panel is marked with various information about the flat panel, such as rated voltage and current. Generally speaking, the household current is within A. Since there are many households that use electricity in the family, there is no need to worry about the current and voltage exceeding the fixed voltage and current

When I opened the box, I saw the millet flat cable board, which was also equipped with a plastic protective suit. It can be seen that millet flat cable board and line phase I are tied together, which is very neat

The user manual of Xiaomi flat panel contains the product introduction, product specifications, characteristics, precautions, etc. of Xiaomi flat panel

At the back of the user manual is the warranty description and list. Well, it's the three guarantee certificate of Xiaomi flat cable board. Ha ha

The whole cable plate is bound by rubber belt, and all wires are neatly arranged and tied around the cable plate.

Take off the protective sleeve, it can be clearly seen that there are three USB cables on the cable tray, which support 5V-3.1A power. When only one cable is used, the current is only 2.1A. When two cables are used by colleagues, the current is only 1.5A. Oppositely, when three cables are used at the same time, the current is only 1A

The same is true for the socket part. There are three sockets. A little bit of knitting here thinks that the design is very considerate, that is, each socket has a protective baffle to prevent dust from entering, which affects the beauty of the flat panel

Out of the wiring port of the flat panel is the switch of the flat panel, which is hard to describe. Anyway, it seems to be integrated with the flat panel, not as colorful as other flat panels. It looks strange

The wiring port is the foresight interface between the connecting wire and the flat panel. If it is not handled properly, the wire is very likely to be broken. The millet flat panel has a wear resistant interface design, which is very good

The interface of the flat panel is also well designed. The plug is also covered with a protective sleeve to prevent contact with heavy air oxygen and oxidation.

The plug uses a three port plug, which is connected to one more ground wire than a two port plug. This connection method has the advantage of preventing static electricity from touching, and the generated static electricity will be transmitted to the ground through the ground wire to dissipate it.

The wire is long enough to see if it is very thick. In fact, it is very simple. It is wrapped with three smaller wires, namely the live wire, the neutral wire and the ground wire. That's why it is so thick. On the surface, the wire actually plays a protective role

At the bottom of the flat panel, there is the basic information of the flat panel. On the left side, there is a meter logo. These characters are engraved on the template during the production, which means that Xiaomi flat panel has been in production for a long time

There are four rubber pads on the base. The rubber pads are designed to prevent slipping and abrasion of the cable board. They are very considerate

It's a user experience. If you plug in Xiaomi, you can only plug in the socket. It's more powerful to use it. Does it look like Xiaomi can only plug in the socket as part of Xiaomi's flat cable board?

Disassembly appreciation:

Such a good cable layout? Xiao Bian wanted to see what was in it. This time, Xiao Bian broke his family and dismantled it.

First, prepare tools, screwdrivers, tweezers, power on tools, crowbars, pliers, and flat wire boards to be destroyed by small braids

First remove the 4 rubber pads

Unscrew the screws at four corners with a screwdriver

Open the gap with the power on tool

Use a crowbar to slowly pry open the back cover of the flat panel. Why does Xiaobian feel like dismantling a mobile phone?

Open the rear cover

When I see the device inside, this section is behind the USB interface for mobile phone charging. Of course, the USB interface cannot be directly connected to the wire like the socket. It must be soldered on the circuit board, which is more urgent and secure

The socket interface is the same as the ordinary socket, which uses copper plate wires, but these copper plate wires are much thicker than other flat wire boards

The switch of the flat panel can't see what to do, only the black one

Continue to disassemble. It looks good. One switch is also independent and directly connected to the wire. Another antenna is also directly connected to the copper wire. This wire is the ground wire, which is responsible for deriving static electricity

Then take out the rest

The flat panel is empty. There is nothing but a frame

Then take a look at the copper wire board that has been removed. It seems that it can still be used now (if you don't get electrified) ha ha! Just kidding, don't try

There is also a meter on a section of the copper plate, well, more than one

When looking at the charging interface of the mobile phone, the three USB's are full of capacitors and inductors, which can convert AC power into DC voltage, lower the voltage and stabilize the voltage, and know the voltage range that can be used by the mobile phone

These capacitors and inductors are directly connected to the circuit board with solder, and are concentrated together

This is the whole circuit board removed

Summary:

In today's society, we have more and more electronic devices, which have to be charged everywhere. However, the previous patch panels are basically the same, with only the power on function. However, there are more electronic devices, which can be plugged in again and again, and again and again are not enough. The full socket is full of charging heads, which makes people bored to death. However, Xiaomi patch panels have solved these problems very well. Xiaomi patch board is small and exquisite, made of high-quality materials, and has re customized core components and optimized the structure to reduce its area by 50% compared with the patch board of the same specification. Each process is carefully carved, and three USB interfaces are designed to successfully solve the problem of more intelligent devices and large number of chargers occupying sockets; Unique double action protection door, recoverable overload device, 750 degree flame retardant level, USB charging safety protection, safety and trustworthiness. Such a delicate, compact, safe and practical millet patch panel costs only 49 yuan. 49 yuan can solve many problems in your life, and it is worth getting started.
