female header, a type of connector.

Applications: This type of connector is widely used in PCB circuit boards in electronics, electrical appliances, and instruments.

Function: Its function is to serve as a bridge in places where circuits are interrupted or between isolated circuits that are not connected, undertaking the task of current or signal transmission. It is usually used together with a female header to form a btb connection; or used together with the end of an electronic cable assembly to form a board-to-wire connection; it can also be used independently for board-to-board connection.

Classification:

Because the specifications used by different electronic products are not exactly the same, female headers also have many models. According to the standard female header product classification of FKMCONN: by pitch, they can be roughly divided into five categories: 2.54mm, 2.00mm, 1.27mm, 1.00mm, and 0.8mm (other special pitches can also be customized as needed); by number of rows, there are single row female header, dual row female header, three row female header, etc.; by packaging usage, there are smt, DIP (straight/right-angle) etc.; at the same time, to match the corresponding pin header, female header plastic heights of different sizes can be customized.

Classification

1. Female headers are divided by pitch: 0.8, 1.0, 1.27, 2.0, 2.54 pitch.

2. Female headers are divided by plastic height and whether they have bosses; bosses are divided into half boss and full boss.

3. Divided by the number of rows of pin headers: single row, dual row, 3 row, 4 row, etc. Currently the maximum is only 4 rows.

4. Divided by installation method: 180 degree is represented by S, 90 degree is represented by W, and SMT is represented by T.

5. Divided by whether height increase is needed and whether positioning posts are needed; there are 2 types of positioning posts, one is an internal positioning post, and the other is an ear positioning post.

Female header terminal types: U terminal and Y terminal

U-shaped terminal, with contact on 3 sides; generally U-shaped terminals are used for low plastic heights

Y-shaped terminal, with contact on 2 sides; generally Y-shaped terminals are used for high plastic heights [1] 

3 row female header inspection items:

1. The overall height of the pin header and female header. (vernier caliper)

2. The pin width of the female header. (visual inspection)

3. Whether the connection between the pin header and the female header is tight.

Note: Please insert and remove the pin header and female header slowly, especially when removing the pin header, try to ensure that both ends of the pin header can come out at the same time, so as not to damage the pins.
