The advantageous effect of twisted-pair cable disclosed by the utility model is：Restrictive coating inner wall is divided into several by the skeleton
A first cavity, the twisted-pair feeder are set in the first cavity, and the section of the locating piece is arc, the both sides of the locating piece
Connect with restrictive coating inner wall, the arc part of the locating piece and restrictive coating inner wall form the second cavity, the locating piece with set
The twisted-pair feeder set in the first cavity contacts, and twisted-pair feeder is fixed in the first cavity by the locating piece, prevents the multiple twin
Line is shifted and is shaken in the first cavity, is reduced the twisted-pair feeder and is carried out friction generation damage, the twisted-pair feeder with skeleton
It is contacted respectively with skeleton and locating piece, because there is the second cavity between the locating piece and restrictive coating, in cable by outer
When power squeezes, the locating piece plays the role of bumper and absorbing shock, and the shape of second cavity changes, by partial action power
Both sides are distributed to, the extruding to twisted-pair feeder in first cavity is reduced, to play the role of protecting twisted-pair feeder.
Description of the drawings
Fig. 1 is the cross section structure schematic diagram of the utility model twisted-pair cable.
Specific implementation mode
The utility model is further elaborated and is illustrated with reference to specific embodiment and Figure of description:
A kind of twisted-pair cable, including restrictive coating 10, the skeleton 20 and several multiple twins that are arranged inside restrictive coating 10
The section of line 30, skeleton 20 is cross structure, and 10 inner wall of restrictive coating is divided into four impartial regions, skeleton 20 and restrictive coating
Region corresponding to 10 forms the first cavity 12, and twisted-pair feeder 30 is set in the first cavity 12, will by increasing by 20 structure of skeleton
Twisted-pair feeder 30 is isolated in cable inner, advantageously reduces the cross-talk between line and line, the equilibrium response of cable is improved, in bone
The centre in 20 section of frame is further opened with through-hole, and stiffener 21 is equipped in through-hole, and stiffener 21 is wire or glass fibers
Dimension reinforced plastics is made, and the tensile property for increasing cable by being equipped with stiffener 21 among skeleton 20 prevents cable from making
With being pullled fracture in the process.
Several locating pieces 11 are equipped in restrictive coating 10, locating piece 11 is set to restrictive coating corresponding with the first cavity 12 10
Inner wall, the section of locating piece 11 are arc, and the both sides of locating piece 11 connects with 10 inner wall of restrictive coating, locating piece 11 and are arranged the
