The JNub is typically composed of a square plastic socket and several neatly arranged square pins. The difference between the JNub connector and the Bullnose connector lies in the removal of the clips on both sides of the simplified Bullnose.

According to requirements, the peripheral dimensions of the Jianniu connector are commonly available in three specifications: 1.27 pitch, 2.0 pitch, and 2.54 pitch. The diameter of the four-row pins used varies accordingly with the pitch. The bottom contact surface with the PCB can be designed as SMT surface mount (as shown in the illustration) or DIP through-hole 180 degrees.

The Simple Bullnose Connector, as the name implies, is a straightforward connector made up of a square plastic socket and a neatly arranged array of square pins. The difference between the Simple Bullnose Connector and the Bullnose Connector lies in the fact that the Simple Bullnose Connector lacks the clips on both sides.

According to requirements, the outer dimensions of Jianniu connectors commonly include 1.27, 2.0, and 2.54 pitch specifications; the diameter of the four-row pins used varies accordingly with the pitch. The bottom contact surface with the PCB board can be designed as SMT surface mount (as shown in the illustration) or DIP through-hole 180 degrees.

The function: After the Jianniu welding is applied to the PCB board, it connects to the corresponding specification IDC ribbon cables, and then forms the circuit connection method required by the designer by combining with other circuits. It is commonly used for transmitting control signals and low currents.
