A type of female connector.

Application: This connector is widely used in PCB circuit boards in electronics, electrical appliances, and meters.

Function: Its function is to function as a bridge between the blocked or isolated circuits in the circuit, and it is responsible for the task of current or signal transmission. It is usually used in conjunction with the motherboard to form a board-to-board connection or used in conjunction with an electronic harness end to form a board-to-wire connection; it can also be used independently for board-to-board connection.

The sample of the mother-in-law product is folded and edited. The models used in different electronic products are not exactly the same. Therefore, there are also many models of the mother-in-law. According to the standard classification of FKMCONN, the product can be divided into 2.54mm according to the spacing. Mm, 1.27mm, 1.00mm, 0.8mm five types (other special spacing can also be customized as needed);

According to the number of rows, there are single row mother, double row mother, three row mother, etc. According to the package usage, there are patch SMT, plug-in DIP (inline/bend), etc.; at the same time, it can be customized for the corresponding pin header. The size of the mother is high.

Folding classification

1. The mother is divided according to the spacing: 0.8, 1.0, 1.27, 2.0, 2.54 spacing.

2, the mother is divided according to the height of the plastic and whether there are bumps, the bumps are semi-convex and full convex.

3, according to the number of rows of pin headers: single row, double row, 3 rows, 4 rows, etc., the current maximum is only 4 rows.

4, according to the installation method: 180 degrees with S, 90 degrees with W, SMT with T.

5. According to whether it needs to be increased, whether it needs to be divided by positioning column, there are two kinds of positioning columns, one is the inner positioning column and the other is the ear positioning column.

Female terminal type: U-terminal and Y-terminal U-shaped terminal, contact with U-shaped terminal Y-type terminal with three faces and general plastic height, contact with two faces, general plastic high Y-type terminal 3 row mother detection item :

1. The overall height of the needle and the mother. (vernier caliper)

2. The pin width of the mother. (visual inspection)

3. Whether the combination between the pin and the mother is tight.

Note: Please slowly insert and remove the pin and the mother, especially when pulling the pin, pay attention to ensure that both ends of the pin can come out at the same time, so as not to damage the pin.
