When the ultrabook is getting thinner and lighter, we pay more attention to the evolution of the shell material, heat dissipation design, screen thinning and so on. But everyone has noticed that the thickness of the ultrabook is so thin that even the port becomes a light and thin obstacle, but these ports are an indispensable configuration for notebooks. So, how to ensure that the port is a barrier to ultra-thinness while ensuring the use of the demand? Mini port /external wiring Compressed port into a key What should I do if the port is too large? The most straightforward way is of course to compress the port thickness. Newer ports, such as HDMI, DP (DisplayPort) ports, etc., have mini port specifications that significantly reduce port size and thickness. In this way, miniporting the port is not an easy obstacle to further compressing the thickness of the notebook. However, not every port has a mini specification, especially old ports, such as RJ-45 (wired network port), D-sub (VGA video port), etc., the thickness is close to 11mm. Such a port is difficult to install in an ultra-thinbook that pursues the ultimate in thinness and lightness. But these ports are indispensable for commercial use. Therefore, many commercial ultrabooks use a patch cord solution, which uses USB, mini DP or dedicated miniaturized ports. After being processed by the patch cord, it is expanded to a conventional D-sub or RJ-45 port. However, the extra patch cord becomes a burden when carrying, and it is troublesome to use for multiple transfer and storage. In this regard, the design of the Sony Pro series is very clever, the specially designed wireless routing can be directly plugged into the power adapter (optional accessory), and then the network cable is inserted into the route, and the wireless signal can be conveniently obtained. Figure: mini port and extension cable are a lot of ultra-pole to avoid the thickness of the port speaker: Sony Pro 11 optional accessories mini HDMI interface and dedicated wireless routing motherboard "embedded" port body thickness reduction, in fact, become Thin and light barriers are not just thick ports like D-sub and RJ45. Even the seemingly thin USB port can become an obstacle in the pursuit of extremely thin and light models. For an ultra-pole of a dozen millimeters, after deducting the thickness of the screen, the outer casing, etc., the thickness of the inner surface of the main surface is often only six or seven millimeters. After the USB port is loaded, the USB port is almost "top of the ground". Don't forget, in the traditional design, the various ports are installed on the top of the motherboard, which takes up more space. Although there is also a mini USB port specification, if you use such a port, it will become very troublesome to insert a USB flash drive and connect a mouse. Therefore, the mini USB is not practical in a notebook. So, what kind of excellent design should I use? From the disassemble diagram, we can see that the port has changed the way it was installed on the top of the motherboard. Instead, the motherboard is hollowed out at the location where the port needs to be installed. At the same time, the port is embedded in the motherboard cutout, thus avoiding The motherboard and the components mounted on the motherboard make the whole machine thicker. However, in this type of installation, the port is only fixed by the side solder joints, and the fixing strength is inevitably reduced. When the port is pulled or shaken, the port is liable to be broken due to the force. In order to avoid this hidden danger, we have seen that in many upper and lower outer casings, there are various kinds of buckles, and the ports are firmly locked to disperse the force of the port, which is a good guarantee. The safety of the whole machine. Figure: The traditional design installs the port on the top of the motherboard, which will increase the thickness of the whole machine: on the Lenovo Ultra 2 and other ultrabooks, the motherboard at the port is hollowed out and embedded in the port, which can reduce the port thickness. Landing is guided by the situation, and large ports are placed in thicker areas of the outer casing. This should be what every manufacturer should have. In fact, there are many examples of this. When the blade shape is popular, the port of the ultrabook is set at the back of the notebook. On the Shenzhou Ui43 and other models, the port design and the whole machine shape are also matched, and the keyboard position is slightly moved backward, while the front of the keyboard is slightly The bulge is flush with the keyboard surface so that the thickness of the front of the keyboard is increased to facilitate the installation of thicker ports such as the D-sub and RJ45. The thinner area under the keyboard is installed with thinner ports such as USB and mini HDMI. In this way, the ports are arranged in an orderly manner, making full use of the height difference between the ultra-poles and placing various ports as much as possible. In the choice of “Topography”, the Dell Latitude E7440 is even better. Its use of the convex shaft not only makes full use of the space behind the whole machine, but also alleviates the problem of insufficient port of the ultrabook. The design of the RJ45 port is even more impressive. The port placed at the boss of the rotating shaft makes full use of the height of the convex shaft. The height of the top of the port is even higher than the height of the C-plane of the ultra-pole, which makes a thickness larger than the C-face. The height of the port is saved on the E7440. There is a large port on the thin model, which is the design that makes clever use of the notebook shape. Figure: The port of Shenzhou Ui43 matches the shape of the fuselage: The RJ45 of the Dell E7440 is placed at the shaft, and the top of the port is even higher than the height of the C-face. Summary: Port design, ultra-thin and easy-to-use, has become a lot of manufacturers. An excuse to simplify the design of the ultrabook port. If only the old ports such as D-sub and RJ45 are omitted by most manufacturers, it is barely acceptable. After all, in the ordinary home field, the demand for these ports is really not high, but if the ultrabook is only Two USB ports, and too close, such port design can only explain the laziness of the manufacturers, and the ultra-thin of the ultrabook is really not too much relationship. Because the design described in this article is the excellent design of PC manufacturers in the face of thin and large ports, with this design, the ease of use of the superbook is greatly increased. From this point of view, the port is by no means a victim of thinning.
