The junction box module is the terminal connection of the cable, the user line and branch trunk line of the wire and cable, and plays an important role. The junction box can be installed in the space bridge, box, pipe and cable trench. It is small in size, does not occupy the effective use space of the building, and is easy to install without cutting off the main cable. The junction box is generally divided into two types according to its purpose. One type is used for connecting the power distribution box to the power supply, and the industrial distribution box is usually referred to as the reference type; The other type is used for communication signal junction box of communication line, which is usually used for network connection. We said that in life, telephone box, cable box, etc.
Junction box module is a connector industry. The junction box module is used for power access or data conversion through shunt, and can output multiple current data or signal equipment. Then, the junction box is usually called M8, while the M12 junction box refers to the line of M8 or M12 socket. It is different from the common socket, which is the power output socket. The common socket has only positive and negative, or has wire, cable box and industrial use. The power output is a pin-shaped I/O port.
