Pai mother is a connector, mainly used in electronics, electrical appliances, instrumentation in the PCB circuit board, mainly play the role of current or signal transmission. Usually supporting the use of pins, constitute a board-to-board connection. Relevant information is as follows:

First, the spacing between the plastic height:

1, row mother in accordance with the pitch division: points 0.8,1.0,1.27,2.0,2.54 pitch.

2, row mother in accordance with the plastic height and whether to bring bumps to divide the bump half convex and full convex.

3, the row of plastic height Our current work is done is complete: 2.1MM, -9.0MM plastic high

4, in accordance with the pin row of the number of divisions: sub-single row, double row, row 3, row 4, etc., currently the highest only 4 rows.

5, divided according to the installation: 180 degrees with S, 90 degrees with W, SMT with T said.

6, in accordance with the need to increase, whether it needs to be divided with positioning column, there are two positioning column, one is the positioning column, one is the ear positioning column.

Second, the row of female terminal type: U terminal and Y terminal / O terminal

U-type terminals, contact with three general plastic height U-shaped terminal

Y-type terminals, contact with two general high plastic surface with Y-type terminal

Third, Pai mother test items:

1, row needle and the overall height of the row mother. (Vernier caliper)

2, the row of pins width. (Visual inspection)

3, the combination of row needle and row mother is close. Board to board connectors
