"A comprehensive explanation of the role and classification of the pin connector" This article is organized by Elecbee.cn for you, purchase connectors, and optimize

Want to know what is the use of the pin connector, we first have a simple understanding of the bottom pin this product, the pin is generally used in the connection of the PCB board, with the pin pair used with the bar, wire connector and so on. Pin is a product in the connector industry, the English name (Pin Header), with a good name for universal connectors.

With the competition of the connector market, the current pin connector is widely used in the PCB circuit board in electronics, electrical appliances, and instruments, usually used with the bar, forming the effect of board-to-board connection, or used with the electronic wiring harness terminal, forming board-to-wire connection, and can also be independently used for board-to-board connection. The role of the pin connector is also to play the function of a bridge between the blocked or isolated circuits in the circuit and take on the task of current or signal transmission.

Because the specifications of the pin connector applied to electronic products are not the same, the pin connector is also divided into a variety of model specifications, and the following is classified according to the standard of the pin connector in the electronic industry:

1, the pin connector can be roughly divided into 0.8, 1.0, 1.27, 2.0, 2.54 spacing according to the spacing.

2, the number of rows of pin connectors can be divided into single row, double row, three rows, four rows, etc., and now the maximum number of rows is four rows.

3, the pins of the row pin connector can be divided into straight feet, curved feet, SMT, etc., and are classified by the size of the needle.

4, the size of the pin connector is classified according to the outline size length, width, thickness and row distance.

5, the pin connector can be divided into SMT(horizontal paste/vertical paste), plug-in DIP(straight insert/bent insert) and so on.

6, the pin connector can be divided into 180° expressed by S, 90° expressed by W, SMT expressed by T, etc.
