How to use connector ? 

As we all know, connectors can be divided into 4 types, differentiated by their function :

1) inline or cable connectors permanently attached to a cable, allowing it to be plugged into another terminal.

2) chassis or panel connectors which are permanently attached to a piece of equipment, allowing users to connect a cable to a stationary device.

3) PCB mount connectors soldered to printed circuit board, providing a point for to a cable or wire to be attached.

4) splice or butt connectors ( primarily insulation displacement connectors ) which permanently join two lengths of wire or cable.
