RJ connectors are mainly used for the connection and signal transmission between devices and components, components and cabinets, systems and sub-systems. They are widely used and are often used in various fields such as aviation, aerospace, military equipment, cars, and industry. Nowadays, electrical connection The variety of adapters is complicated. If you want to improve the reliability of electrical adapters, accurate selection of adapters is very important.
When choosing an RJ network connector, the first reference element is its own electrical parameters, because the electrical parameters require that the RJ connector is the main electromechanical component that connects the electrical circuit.
The extra voltage that must be considered is the additional voltage. The additional voltage is also called the operating voltage. It usually indicates the highest operating voltage marked by the manufacturer. It is mainly affected by the insulating material used by the connector and the distance between the touch pairs. Because some components and equipment may not be able to fully utilize all their functions if they are lower than their extra voltage, this element should also be considered when thinking about it, although many connectors produced today can still operate normally if they are lower than the extra voltage.

The RJ network cable has a total of 8 cores, and the colors are orange, blue, green, brown, white orange, white blue, white green, and white brown. The method of connecting the crystal head is as follows
(1) The wiring sequence of the crystal plugs at both ends of the network cable should be the same.
(2) The default wiring sequence is: white-orange, orange, white-green, blue, white-blue, green, white-brown, brown (summary summary: color sequence "orange blue green brown" "white first" "white blue white green change ")
After peeling off the outer gray cable with wire strippers (the stripping length is about 3cm), you need to straighten the wires. After arranging the color sequence, use scissors or wire strippers to cut the wires, and the remaining approximately (1.5-2cm)
Push the color line into the crystal head, clamp the front metal head with the holder, and hear a "click" to indicate that it has been clamped.
Test whether the network cable is intact and use a cable tester to test.
