The difference between the round hole pin header and other concepts.Elastic contact Production

　　1. The main differences are the conceptual differences of "round hole pin headers", "terminals" and "connectors"

　　①Round hole pin header, namely CONNECTOR. Also called the connector round hole pin header. It is a component that electronic engineering and technical personnel often touch. Also known as connectors, plugs and sockets in China. Generally refers to the round hole pin header of electrical appliances. That is, two devices are connected to transmit current or signal.

　　②Connector is a kind of positioning connector for connecting electronic circuit. It is composed of 2 parts, namely, plug-in and connector. Under normal circumstances, they can be completely separated. The similarity between switch and connector lies in the contact condition of the contact pair. The modification of the switch completes the purpose of changing the connected circuit, and the essential difference is that the connector only needs to be pierced and removed. The switch can complete the circuit change on its body, but the connector cannot be completed on the body. The contact pair of the connector has a fixed corresponding connection. Therefore, the connector can also be called a round hole pin header.

　　③Connecting terminal, English name Terminal (terminal). It is an accessory product used to complete electrical connections, and is industrially divided into the category of round hole pin headers. The terminal block is used to facilitate the connection of the wire. It is originally a piece of metal enclosed in insulating plastic, with holes at both ends, which can penetrate the wire. Terminals can be divided into WUK terminal blocks, series, series, etc.

　　2. From the scope of ownership, the difference is "round hole pin header", "terminal", "connector"

　　① "Round hole pin header = connector" is the first category, and the terminal block is only one of the "round hole pin header" categories

　　The difference between the connector and the round hole pin header?

　　The round hole pin header is the connection between the line and the line; the connector is the connection between the line and the board and the box. In real life, people often refer to the same thing in confusion.

　　②The terminal belongs to some of the round hole pin headers. The round hole pin header is a general term. The round hole pin header that we commonly used in the past generally includes two major types: housing and terminal. The housing is mostly plastic, which plays a role in maintenance, and the terminal is metal, which is universal.
