A Wire-to-board connector is a connector used to connect wires to a circuit board. It usually consists of two main parts: a socket (socket) and a plug (header). The socket is usually mounted on the circuit board, while the plug is connected to the wire. The following is a general classification description of wire-to-board connectors:

Pin arrangement: Wire-to-board connectors can be classified and described according to their pin arrangement. Common arrangement methods include straight insert type (upright type), patch type, Angle insert type (right Angle type) and so on. The in-line pin is perpendicular to the bottom of the connector, the patch pin is parallel to the bottom of the connector, and the Angle pin is connected to the bottom of the connector at an Angle.

Number of pins: Wire-to-board connectors can be classified and described according to their number of pins. The number of pins can range from a few pins to hundreds of pins, and the common number of pins is single row, double row, three row, etc.

Pin spacing: Wire-to-board connectors can be classified and described according to the spacing between pins. Pin spacing is usually measured in millimeters (mm), with common spacing being 2.54mm (0.1 in), 2.0mm, 1.27mm, and so on. The choice of pin spacing depends on the needs of the specific application and the size of the electronic component.

Pin shape: Wire-to-board connectors can be classified and described according to the shape of the pin. Common pin shapes include round pins, square pins, knife pins, etc. The choice of pin shape usually depends on the design of the connector and the environment in which it is used.

Pin material: Wire-to-board connectors can be classified and described according to the pin material. Common pin materials include brass, phosphor bronze, stainless steel, etc. The choice of material will affect the electrical conductivity, corrosion resistance and mechanical strength of the pin.

Current and voltage levels: Wire-to-board connectors can be classified and described according to the current and voltage levels they support. Different connector designs and material choices can support different current and voltage requirements to meet the power needs of a specific application.

Application field: Wire-to-board connectors can be classified and described according to their main application field. It is widely used in electronic equipment, circuit boards, embedded systems, consumer electronics, industrial automation and other fields.
