What are the applications and functions of round hole headers?
The application of round-hole female header: This kind of connector is widely used in PCB circuit boards in electronics, electrical appliances, and meters.
The role of round hole row mother: its role is to play the function of a bridge between blocked or isolated circuits in the circuit, and undertake the task of current or signal transmission. It is usually used with round-hole female header to form a board-to-board connection; or used with an electronic wiring harness end to form a board-to-wire connection; it can also be used independently for board-to-board connection.
1. Round-hole headers are divided according to the spacing: 0.8, 1.0, 1.27, 2.0, 2.54 spacing.
2. The round hole female header is divided according to the height of the plastic and whether it has bumps. The bumps are divided into semi-convex and full-convex.
3. Divided according to the number of rows of needles: single row, double row, 3 rows, 4 rows, etc. At present, the highest is only 4 rows.
4. Divided according to the installation method: 180 degrees is represented by S, 90 degrees is represented by W, and SMT is represented by T.
5. According to whether the height needs to be increased and whether it needs to be equipped with positioning pillars, there are two types of positioning pillars, one is the inner positioning pillar and the other is the ear positioning pillar.
