As a simple horn connector, Jane is usually a square-shaped plastic socket and a number of square needles arranged neatly. The difference between the simple cow connector and the horn connector is that the simple horn removes the buckles on both sides. According to the requirements, the outer dimensions of the simple cattle connector are commonly used in 1.27 pitch, 2.0 pitch, and 2.54 pitch; according to the spacing, the diameter of the square pin used is also changed accordingly. The bottom and PCB contact surface can be designed as SMT patch or DIP in-line 180 degrees. Function: After the Jane is soldered on the PCB, it is connected to the IDC cable of the corresponding specification, and then combined with another circuit to form the circuit connection required by the designer, usually used to transmit control signals and weak current.
