Exterior
Millet has three USB ports, one more than Oerlikon, and the USB hole pitch is also wider than the Oribo, plug and unplug experience is very smooth, and the Oribo USB hole spacing is too narrow, plug and play better than millet. This allows Xiaomi to beat Oerlikon in the USB interface.
Ourui Bo can be seen that the appearance of the size of millet longer and wider than the higher, more heavier, I discovered the advantages of size and weight Ourui Bo in actual use, see below
It is because of Oerlikon's large volume that when inserting multiple plugs, the Oerlikon busbars will not be tilted and the millet busbars will be lifted to one side by the plug pressure. There is discomfort.
Both plugs have overload protection, but Oerlikon has set up an independent overload protection switch.
Dismantling
On the back of each of the two rows, there is a parameter description of the product. Xiaomi uses an engraving version, while Oerlikon is printed in black and has a QR code downloaded by the app . No exposed screw holes on the back, all covered with rubber feet cleverly, millet with four rubber stickers, while Oerlikon uses two bars instead, the actual drag and drop test Oerlikon plug row is more stable. The plugs are square and the company LOGO is engraved . After removing the foot pad, four triangular screws appeared, which made it difficult for the user to open it on his own, and the author dismantled it.
Both inserts are one-off, non-injection molded shells, and many detailed internal buckles are not easy to remove. After the removal of the four external screws of Oribo, there were still two hidden screws inside. This design made the author unpredictable, and the author could only dismantle it violently.
Layout and layout
The two rows of cables are very neat, solder joints are clear, contacts are good, there is really no fly line to open, circuit board design is also very reasonable. Oribo is opened from the front, so we can see the spring-type protection door, millet need to remove the copper wire to see the protection door, this kind of protection door is very necessary for users with children at home, the author did not use the screwdriver to force into the jack, It seems that both are very good at protecting the door.
The dismantling of the protective doors of the two sockets shows that the integrated protective door used by Oerlikon and the millet are assembled. Although the functions of the two are identical, the cost of the integrated protective door is slightly higher.
Looking at both copper strips, both use one-piece tin-phosphor-copper strips as conductors, which have a larger surface area and can provide good electrical conductivity and heat dissipation. At present, there are not many products using integrated copper strips. Intuitively, the material of the two copper strips is almost the same, but the copper strips of millet are slightly thicker than those of Oribo. The difference is very small, and it is almost impossible to distinguish them without careful comparison. Oerlikon engraved the brand LOGO on the copper strip.
The switch between the two is very different, Oerlikon uses an electronic touch switch, millet uses a paddle switch, it is difficult to say who is superior, from the map is not difficult to see that the manufacturing process of the touch switch to be more complex, which should be fixed More solder joints are on the circuit board and the cost is relatively high.
Oerlikon has set up a separate overload protector. Millet designs the overload protector switch and the power switch in one, and one switch controls two functions. The author has a surprising discovery that the location of Xiaomi's switch plastic on the photo has obvious traces of being burned. This should be the “credit†of the soldering iron during processing. If it is not dismantling, it is really hard to find. There are also minor mistakes in coming to the big brands, and Oerlikon’s independent overload switches are much more neat.
The author found a silver bar buried on the board of Oribo. What is the effect of this? In fact, this part of the silver is the hot line, most manufacturers are connected with wire, to know that each additional wire in the row plug may be due to poor solder joints lead to open circuit, in order to minimize the use of wire, directly to the fire wire design in the circuit board On top and cover the tin layer to increase conductivity. This process is like the construction of electrical engineering. All wire joints must not only be tightly connected to the copper wire, but must be coated with a layer of heated liquid tin on the outside to ensure good electrical conductivity and heat dissipation. This is the reason why only two wires are seen inside the Oerlikon Bar.
Speaking of the wire, we can see from the photos that the two wires inside the Oerlikon busbars are covered with a layer of white soft plastic skin. What does this play? The internal space of the plug is narrow and tight, and the assembly process, welding process and use process may cause damage to the blue insulating layer. If the blue insulated wire is damaged, there is a risk of short circuit, and even more serious consequences may occur, increasing the wire sheath. This is to protect the insulation from being scratched or crushed by internal components. It must be said that Oribo wants to be very thoughtful in detail design.
Looking at the contrast of the wires, Oerlikon used the wire of Akihabara. From the appearance, it can be clearly seen that the wire diameter of Oeremberg is a little bit thicker than that of millet. The cutaway view of Oerlikon's outer protective layer is thicker than the protective layer of millet. As for the wire diameter difference is not obvious, remove the insulation layer can see the millet is using 42 wire copper wire, Oerlikon uses a 25 wire copper wire, the same wire diameter, the less the number of copper wire, the more conductive properties OK, the price is higher. It seems that the quality of Akihabara's professional wire is very good.
Both lengths of the strips have been rigorously tested to ensure that they are not too long and lead to wire redundancy. The author finds that the welding process between the blue conductors and the zero conductor copper strips of the Oreibo Strip ensures that the contact surfaces have good electrical conductivity and that the connections are more reliable and difficult to disconnect.
After dismantling and comparing the two types of plugs are very good, in terms of design have their merits, but Oerlikon plug row slightly better, especially in small details such as: wire protection sleeves, circuit board coated tin wire, touch welding connection technology, Akihabara cables are better than millet strips. Of course, the cost is naturally higher than that of millet. The millet plugs have a slight flaw in the small details of the switch welding, I do not know if it is an individual case or a product common problem.
