USB data line process


USB data line process

A: The USB data cable should be cut obliquely and cut to the required twisted pair length, at least 0.6 meters, and at most 100 meters. Then twisted wire stripper was used to remove the twisted-pair jacket by 2-3 cm. Some twisted pair cables contain a soft nylon cord that can be burned with a lighter or carefully clipped. If you peel off the twisted-pair jacket, you feel that the exposed area is too short, and when you make an RJ-45 connector, you can hold the twisted-pair jacket and pinch the nylon thread to peel off under the skin. A longer exposure line can be obtained; a line with a barrier can only be stripped again.

II: Twisted pair cable after the USB data cable is stripped.

Three: The next step is to perform the operation of the line. Put the orange line in the exposed twisted pair to the front of the person, the brown line to the person's preference, the green line to the left, and the blue line to the right. Wiring times: Upper: Orange Left: Green: Brown Right: Blue.

Four: Put the green line and the blue line on the center, but the orange line and the brown line will not move, the number of connections, the left one: the orange left two: the blue left three: the green left four: brown.

Five: Carefully peel off each pair of lines, white mixed lines facing forward. Since we are making joints in accordance with the specifications of EIA/TIA568B, the line pair colors are inevitably decisive.

6: The exposed twisted pair of USB data cable is cut with hinge cutters or diagonal pliers to a length of only about 14mm. The reason for leaving this length is to comply with EIA/TIA specifications. You can refer to the related RJ- See the 45-gauge and twisted-pair manufacturing specifications. Finally, each line of the twisted pair is placed in the pin of the RJ-45 connector in sequence. The first pin should be put in the white-orange line, and so on.
