What are the wires in the case for

Hello everyone, I'm a craftsman.https://www.ateamshops.com/chicago-cubs/anthony-rizzo.html The expansion of the computer is basically determined according to the motherboard used. The number of interfaces provided by the motherboard will increase the expansion capability of the computer. In addition to the IO interface, the current motherboard also provides more built-in pin-type interfaces, but most people are unfamiliar with these interfaces. Today, Xiaojiang will briefly introduce the names of the common pin-type interfaces on the motherboard. and function.https://www.vteamsshop.com/golden-state-warriors/stephen-curry.html The first is the connection cable of the front panel of the chassis, which is usually divided into two types: power on/off, restart and indicator light, and the other is the front expansion interface similar to USB. First of all, let's talk about the front wiring of the switch. Usually, JFP1 will be marked next to the interface (different brands of motherboards may have different names), which usually consists of four sets of pins. According to the pair, the upper left two are the power indicator lights, the lower left is the hard disk indicator light, the upper right corresponds to the power-on button, and the lower group is the restart button. Most of these groups of lines on the chassis are designed separately, and the functions they represent will be marked. However, the working indicator and power indicator of the hard disk are divided into positive and negative. Although there will be no hardware failure when connected reversely, the lights will not light up.https://www.wteamsshop.com/los-angeles-dodgers/clayton-kershaw.html Next, let's talk about the front expansion interface. Here we will introduce the common USB2.0, USB3.0 and some Type-C separately: the first is the most common USB 2.0 connector. It is generally located at the bottom of the motherboard, and usually has a large USB name written on it. The whole is composed of 9 pins, and the missing one also plays a certain role in slack, preventing users from inserting it backwards. The USB 2.0 wiring of the chassis usually adopts this one-piece connector. As long as it is inserted according to the position of the notch, in most cases, the connection will not be wrong. The second is the higher-level USB3.0 interface. This interface is generally located on the right side of the motherboard, with a total of 19 pins. In some cases,https://www.xteamsshop.com/pittsburgh-steelers.html it is vertical as shown in the figure below. Sometimes some motherboard models also rotate this connector 90 degrees. There is also a gap on the interface, which plays a role in resting. The front USB 3.0 cable on the chassis is also designed with 19 pins, and there is a protrusion on one side, which corresponds to the missing slot on the motherboard to prevent users from connecting it in reverse. Furthermore, with the upgrade of mobile device interfaces, some desktop chassis will also use front type-c interfaces, which leads to the fact that motherboard manufacturers now also provide type-C headers on some mid- and high-end models. The rate of this interface is generally not lower than the USB 3.0 standard, that is, not lower than 5Gbps. And this interface has no positive or negative distinction, so you don't need to pay special attention to the wiring direction, just find the right wiring and connect it. The front type-C of the case is not very popular at present, only some cases with a medium price or above will be equipped with it. Find the right interface and connect it. This interface is not yet a mainstream interface, but the development trend has indeed begun to slowly work towards this aspect. Finally, let me briefly say: why is the front panel wiring of the chassis still separated? It can be seen from the above introduction that the interface extension cables inside the chassis are basically made into integral interfaces, and have a set-up setting, which is not only easy to install but also not prone to problems. However, the cables on the front panel of the chassis are still separated. Even though most motherboards now use 9-pin connectors, there is still no manufacturer to integrate the four sets of cables. In fact, this is a problem left over from history, because this set of lines is not a standard interface. The host interface in the early years was not as standardized as it is now. In many cases, some motherboards are a group of two horizontal lines, and some are indeed vertical, resulting in Manufacturers have no way to start. Therefore, the separate design can not only solve the problem of different interface design standards, but also facilitate mass production. And now there are many motherboards or chassis that come with four-in-one adapters, making it easier for customers to install jumpers. Although this design sacrifices compatibility to a certain extent, it can greatly simplify the installation. And with the progress of motherboard and chassis manufacturers, I believe this legacy problem can be solved soon.
