Network cable production:
(1) Cut: use knife-edge scissor of press line pliers to cut network cables with appropriate length.
(2) Peel: use knife-edge of press line pliers to shear cables orderly, then put wire heads on peeling blade, make
wire heads touch baffle, then slightly clench pliers and slowly rotate it, let knife rip off the protecting rubber skin of
twisted pair, peel off the skin (note: strip as long as thumb
’
s length).
【
Tip
】
: The length between baffle and peeling blade of press line pliers usually is just same length as plug
’
s, which
can effectively avoiding peeling too long or too short. If peel too long, the network cable will look ugly, meanwhile, it
can not be stuck by plug, the connection point can easily get to loose; if peel too short, because of the existing of
protecting skin, cables become too thick to plug into the bottom of plug, which results in plug can not contact perfectly
with cable cores. Production can not be success as well.
(3) Sort: after removing outer protecting skin, you can see four pairs of twisted-pair
’
s eight cores, and each pair
’
s
color is different. Each pair of two allied core wires consists by one core wire stained with a corresponding color and
one core wire stained with white and little corresponding color. The colors of four panchromatic core wires are: brown,
orange, green and blue. Each pair is entangled with each other. When produce network cable, these four pairs of
eight thin cores should be disassembled, tidied up, straightened and sorted in sequence according to the following
wire order regulation.
Put the side with plastic spring of plug down, up the side with pin, make the end with pin towards to the opposite
direction of yourself, the end with square hole towards to yourself, simultaneously, the far left is the first wire, the far
right is the eighth wire, followed by the remaining order.

(4) Cut: straighten wires as right as possible (do not wrap), press to flat (do not overlap), tighten and tidy up (lean
against each other in one direction), and then use press line pliers to cut flush. In this way, after inserting twisted pair
into plug, each wire can well contact plug
’
s pin, which avoids bad connection. If the former skin is peeled too long,
then it can be cut shorter at this stage. Except outer insulation skin, the remained part is about 14 mm, which length
can rightly insert each thin wire into corresponding trucking. If this part is too long, for one hand it can increase
mutual crosstalk, because allied wires ate no longer twist together, for the other hand, owing to the plug can not pin
the sheathes, cables derail from plug, which can cause bad connection or even Interruption.
(5) Insert: use one hand
’
s thumb and middle finger to nip plug, the plastic shrapnel of plug faces downside, its pin
towards the opposite direction of yourself, using your forefinger to hold it. Other hand nips the rubber skin which is
outside of twisted pair, slowly inserts eight wires along RJ-45
’
s eight truckings with proper force until reaching the top
of trucking.
(6) Press: when all wires are in place, and all wires
’
sequence is correct after thoroughly checking over through
connectors, then you can use press line pliers to make RJ-45 plug. Push one head of RJ-45, from the side without
