Simple cow is usually a four-sided plastic socket and a number of neatly arranged square pins. The difference between a simple bull connector and a bullhorn connector is that the simple bullhorn removes the clips on both sides.
Based on demand, the peripheral dimensions of the simple cow connector commonly used 1.27 pitch, 2.0 pitch, 2.54 pitch three specifications; according to the different spacing, the use of the quadrilateral row of pins in the diameter of the corresponding changes. The bottom and PCB board contact surface can be designed for SMT SMD or DIP direct 180 degrees.

Depending on the demand, the peripheral dimensions of the simple cow connector commonly used 1.27 pitch, 2.0 pitch, 2.54 pitch three specifications; according to the different pitch, the diameter of the four-way row of pins used also change accordingly. The bottom and PCB board contact surface can be designed for SMT SMD (shown in Figure 1) or DIP direct 180 degrees.
Simple cow soldered to the PCB board, connected to the corresponding specifications of the IDC cable, and then with another circuit composed of the designer needs to achieve the circuit connection. Usually used to transmit control signals and weak current.
