Connector, that is, CONNECTOR. It is also called connector, plug and socket in China. Generally refers to the connector. That is, the device that connects two active devices to transmit current or signal. It is widely used in military systems such as aviation, aerospace, and national defense. Connectors are a component that our electronic engineering technicians often come into contact with. The SIM card connector is a common smaller connector that we use in electronic products such as mobile phones and computers. Its function is very simple: to build a bridge of communication between blocked or isolated circuits in the circuit, so that the current flows and the circuit completes the predetermined function. Connectors are indispensable components in electronic equipment. If you follow the path of current flow, you will always find one or more connectors. The connector form and structure are ever-changing. There are various types of connectors depending on the application target, frequency, power, application environment, etc. For example, the connector used for lighting on the court is very different from the connector for the hard disk drive and the connector for igniting the rocket. But no matter what kind of connector, it is necessary to ensure that the current flows smoothly and reliably. In general, connectors are not limited to connecting currents. In today's rapidly developing optoelectronic technology, the carrier for transmitting signals in optical fiber systems is light. Glass and plastic replace the wires in general circuits, but connectors are also used in optical signal paths, and their functions are the same as those of circuit connectors.  

Use of connectors:

Improving the production process Electrical connectors simplify the installation process of electronic products. It also simplifies the mass production process; easy to repair If an electronic component fails, the failed component can be quickly replaced when a connector is installed; easy to upgrade With the advancement of technology, components can be updated when a connector is installed, and new and more complete components can be replaced; improve the flexibility of design The use of connectors allows engineers to have greater flexibility when designing and integrating new products, as well as when using components to form systems. As the structure of connectors becomes increasingly diverse, new structures and application areas continue to emerge, it has become difficult to get used to trying to use a fixed form to deal with classification and naming issues. Despite this, some basic classifications are still useful.

Electronic connectors have also developed along with the intelligent electronics industry. They are a new type of manufacturing industry. my country developed them relatively late and for a short period of time, so there is a large room for development. The card socket connector is a part of the domestic development that is relatively fast.
