Round hole pin row female connector
Round hole female row pin connector
English name: Pin Header.
This kind of connector is widely used in electronics, electrical appliances, and PCB circuit boards on the surface. Its role is to function as a bridge between blocked or isolated circuits in the circuit, and is responsible for current or signal transmission. task. Generally used with female headers to form a board-to-board connection; or used with electronic wiring harness terminals to form a board-to-wire connection; it can also be used independently for board-to-board connection.
Round hole pin header and female feature: single row and double row, straight needle and curved needle, the pin spacing is 2.54mm and 3.96mm, various pin lengths.
Round hole pin row classification
1. The mother row is distinguished according to the interval: 0.8, 1.0, 1.27, 2.0, 2.54 intervals.
2. Female headers are distinguished according to the height of the plastic and whether they have bumps. The bumps are divided into semi-convex and full-convex.
3. According to the number of rows of needles: single row, double row, 3 rows, 4 rows, etc., now the highest row is only 4 rows.
4. Different according to the device method: 180 degrees is marked with S, 90 degrees is marked with W, and SMT is marked with T.
5. According to whether you need to increase the height and whether you need a positioning column, there are two types of positioning columns, one is the inner positioning column and the other is the ear positioning column.
Female row terminal type: U terminal and Y terminal
U-shaped terminal, touch U-shaped terminal with 3 general plastic bumps on the surface
Y-type terminal, touch with 2 sides, generally high-plastic Y-type terminal
