Want to know what the use of the pin connector, we first briefly understand the pin this product, the pin is generally used in the PCB board connection, with the pin paired with the use of the row of female, wire-end connectors and so on. Pin is a product in the connector industry, the English name (Pin Header), has a universal connector's good name. Along with the competition in the connector market, now the pin connector is widely used in electronics, electrical appliances, instruments in the PCB circuit board, usually used in conjunction with the mother of the row, constituting the effect of board-to-board connection, or with the electronic harness terminals, constituting a board-to-wire connection, can also be used independently for board-to-board connections and so on. The role of the pin connector is also in the circuit is blocked or isolated between the circuit, to play the function of a bridge, the task of current or signal transmission.

As the pin connector is applied to electronic products are not the same specifications, so the pin connector is also divided into a variety of model specifications, the following in accordance with the electronic industry pin connector standards for classification: 1:

1. Pin connector according to the pitch can be roughly divided into 0.8, 1.0, 1.27, 2.0, 2.54 pitch, etc..

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

3. The pin of the row of pin connectors can be divided into straight, curved, SMT, etc., and the size of the pin to be classified.

4. The size of the pin connector according to the form factor length, width, thickness and row distance to be classified.

5. Pin connector according to the package can be divided into SMD SMT (lying / standing paste), plug-in DIP (straight / curved plug) and so on.

6. Pin connector can be divided into 180° with S, 90° with W, SMT with T, etc. according to the installation method.
