Connectors are not only used in items such as smartphones and computers that are closely related to our daily lives, but also have a wide range of applications to all electronic related terminal devices. Due to the need for connectors to handle various design styles and applications, there are a wide variety of connectors. What kind of connection effect will the use of connectors produce? Let's take a computer as an example to illustrate. Firstly, it is the memory slot. A slot installed on the PCB board inside the computer chassis for connecting to a memory card. Secondly, it is used as a connector for the internal PCB board of the computer. The circuit is composed of multiple PCBs according to different functions, and connectors are required to connect these PCBs. In addition, connectors are also needed to connect the LCD screen and keyboard to the PCB board. Finally, there are IO connectors. This is a connector used to connect computer hosts, printers, mobile devices, televisions, and other external devices.
