How to connect a network cable with a shielding layer

　　The wiring process of a network cable with a shielding layer requires careful operation to ensure good electrical connection and shielding effect. The following are the specific wiring steps:

　　Prepare tools and materials

　　wire strippers

　　Crimping pliers

　　Shielded crystal head

　　Sidewire meter (for testing connections)

　　Network cable with shielding layer

　　Stripping and finishing

　　Peel off the outer skin: Use wire stripping pliers to remove about 1.5 cm to 2 cm of the outer skin of the mesh wire, taking care not to damage the inner wire core and shielding layer.

　　Finish the shielding layer: Gently arrange the shielding layer (aluminum foil layer or braided mesh layer) to avoid it being torn or damaged. For double shielded network cables, special attention needs to be paid to distinguish between the two layers of shielding.

　　III. Core sorting and insertion of crystal head

　　Sort the wire cores: According to the T568B or T568A standard (usually using T568B), the wire cores are arranged in the order of white orange, orange, white green, blue, white blue, green, white brown, and brown.

　　Insert the crystal head: Insert the sorted wire core into the jack of the shielded crystal head, making sure that each wire can be inserted in place. The metal shell of the shielded crystal head will be used to connect the shielding layer.

　　Fourth, connect the shielding layer

　　Connect the shielding layer with the crystal head: Connect the shielding layer (aluminum foil layer or braided mesh layer) tightly with the metal shell of the shielding crystal head. If one side of the aluminum foil layer is non-conductive, make sure that the conductive surface is in contact with the metal shell of the crystal head.

　　Ensure electrical continuity: Observe whether the interface of the network device or socket has a reed, which allows the socket to touch the metal shielding layer on the RJ45 plug with shielding function, so that the shielding layer is connected as a circuit.

　　Five, pressing the crystal head

　　Put in the crimping pliers: Put the shielding crystal head that plugs in the wire core and connects the shielding layer into the crimping pliers.

　　Press hard: Press the crimping pliers hard to ensure that the crystal head is tightly connected to the wire core and shielding layer. A "click" is usually heard to indicate that the pressing is complete.

　　VI. Testing and Grounding

　　Test connection: Use the side cable meter to test the connection of the network cable and ensure that all the indicator lights flash in sequence to indicate that the connection is normal.

　　Grounding treatment: The shielded network cable must have a good grounding system. Direct external interference signals to the earth through the diversion ground wire. If there are only neutral and live wires, without the ground wire, the shielded wire will not play any role. Grounding can be done by connecting the shielding layer (or special ground wire) in the network cable to the ground terminal of the network equipment or socket, or by other means to ensure that the shielding layer is connected to the earth.

　　VII. Precautions

　　Avoid damaging the shielding layer: Be careful not to damage the shielding layer when stripping and finishing the wire core. If the shielding layer is damaged, it will affect its anti-interference performance.

　　Select the correct crystal head: A shielded crystal head with a metal casing must be used to ensure electrical continuity of the shielding layer.

　　Check the grounding system: Before connecting the shielded network cable, make sure the grounding system is in good condition and reliable. If the grounding is poor, the shielding layer will not function.

　　Through the above steps, you can successfully connect the network cable with a shielding layer and ensure that it has good electrical performance and anti-interference ability.
