Don't forget to learn during of Novel coronavirus pneumonia,ChangJiang connectors takes you to learn together-the role and classification of pin connector. Want to know what the pin connector is useful for, let's first briefly understand the product of the lower pin. The pin is generally used on the connection of the PCB board, and there is a row female and wire end connector used with the pin. Wait. Pin header is a product in the connector industry.Pin Header has the good name of universal connector.
The current pin connector is widely used in PCB circuit boards in electronics, electrical appliances, and meters. It is usually used in conjunction with a female header to form a board-to-board connection effect, or it is used in conjunction with an electronic harness terminal to form a board-to-wire connection. It can also be used independently for board-to-board connection. The pin connector also functions as a bridge between blocked or isolated circuits in the circuit, and plays the role of current or signal transmission.
Since the specifications of the pin connector applied to electronic products are not the same, the pin connector is also divided into various models and specifications. The following is classified according to the pin connector standard of the electronics industry:
1. Pin connector can be roughly divided into 0.8, 1.0, 1.27, 2.0, 2.54, 3.96 pitch and so on according to the pitch.
2. The row number of the pin connector can be divided into single row, double row, three row, four row, etc. Now the row number is four rows.
3. The pins of the pin connector can be divided into straight pins, bent pins, SMT, etc., and also classified by the size of the pins.
4. The size of the pin connector is classified according to the overall size, length, width, thickness and row pitch.
5. Pin headers can be divided into SMT (horizontal / vertical), plug-in DIP (straight plug / bent plug) and so on according to the package.
6. Pin headers can be divided into 180 ° using WV, 90 ° using WR, and SMT using S.
