What are the applications and functions of "needle arrangement factory" round hole arrangement?

Application of round hole bushing: this connector is widely used in electronic, electrical, instrument PCB.

Round hole bushing function: its function is in the circuit is blocked or isolated between the circuit, play the function of bridge, take on the task of current or signal transmission. It is usually used in conjunction with the round hole exhaust bus to form a plate-to-plate connection; Or it can be used in conjunction with the end of electronic wire harness to form a plate-to-wire connection; It can also be used independently for plate to plate connection.

1. Round hole bus is divided according to spacing: 0.8, 1.0, 1.27, 2.0, 2.54 spacing.

2. The round hole layout is divided according to the plastic height and whether there are convex points, which can be divided into semi-convex and fully convex.

3. According to the number of rows of pins, there are single row, double row, 3 row, 4 row, etc. At present, the highest row is only 4 row.

4. Divided by installation: 180 ° is represented by S; 90 ° is represented by W; SMT is represented by T.

5. According to whether elevation is needed or not and whether positioning column is needed, there are two types of positioning column, one is internal positioning column and the other is ear positioning column.
