Types and application of round hole row needle and row mother?

发布时间:2021-07-05

Regarding the current electronic market, the demand for round-hole pin and female connectors is very large, and their pin and female connectors are generally widely used in PCB circuit boards in electronics, electrical appliances, and exterior equipment. And according to the needs of different devices, there are many types of standard classifications of headers and headers. I remember that I also talked to us about the functions and influencing factors of the header and female connector before, then I will give you a detailed description of the round-hole header and female type classification and the precautions for use.


Round hole pin header type classification:

1. Number of rows: single row, double row, three row, four row, etc.

2. Distance: 0.8, 1.0, 1.27, 2.0, 2.54, etc.

3. Installation method: 180 degrees is indicated by S, 90 degrees is indicated by W, and SMT is indicated by T.

4. Positioning column: inner positioning column, ear positioning column.

5. Stitches: straight feet, curved feet.

6. Packing: blister pack, roll bag, bulk pack.


Note for the use of round hole pin headers:

1. When using the pin header and female connector, please slowly insert and pull out the round hole header and header, especially when pulling out the header, do not use too much force to avoid damaging the pins, pay attention to try to ensure the ends of the header Can come out together.

2. The header and female connector has been in use for a long time. Please pay attention to often remove the dust in the pinhole of the header. Once the dust accumulates too much, it will cause the contact between the header and the header to be bad. The use of the mother will show some current or unstable signal transmission.

3. In the process of using the female connector with round-hole pin header, pay attention to not inserting it in reverse or misplacement. When the plug is not well, you can't pull it out forcibly to avoid damaging the pin header.

4. When the number of rows of pin header connectors is relatively large, regarding the connection between the header and the header, pay attention to whether the headers are aligned with the pinholes of the header, or if they are not aligned, once they are connected Simple insertion leads to bending of the pin header.

5. When installing the pin and female connector, if you find that the pin is lacking in the number of pins, you should choose to replace it immediately. Otherwise, the use of the pin and female connector is relatively simple to show some problems and other problems.


Recommendations for purchasing round hole pin headers and female headers

1. When purchasing round-hole pin headers and headers, consider the application environment of the header headers and headers, especially the working conditions of header headers. For example, the environmental requirements of some equipment are high temperature resistant, and some need to prevent moisture and so on. Therefore, the appropriate round-hole pin headers should be selected according to the environmental requirements of the equipment.

2. When we buy the round hole header header, we must understand the various functions of the header header before purchasing. Because header headers of different standards have different functions, and most header headers cannot be used interspersedly, otherwise, it will directly affect the quality of the use of round hole header headers.
