Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.

A carrier cable special for a power modem comprises two carrier cable cores 1, an inner sheath 11 is arranged outside the two carrier cable cores 1, the inner sheath 11 is made of polyolefin materials such as PE or PVC and has certain hardness, and the two carrier cable cores 1 are coated by the inner sheath 11 together, so that the two carrier cable cores 1 are kept in a relatively parallel state.

Referring to fig. 1, inner sheath 11 is equipped with elastic sleeve 12 outward, elastic sleeve 12 specifically is stainless steel spring housing, stainless steel spring housing possesses elasticity, movable space is left to inner sheath 11 and elastic sleeve 12 inboard, elastic sleeve 12 has good antitorque effect to the carrier cable core 1 by inner sheath 11 cladding, when the cable receives the flexible turn-round of external force hank, on the one hand, elastic sleeve 12 self can at first take place to twist reverse, with external force to the torsion isolation of carrier cable core 1 outside, thereby it takes place the effect that the hank wound takes place for two carrier cable cores 1 to play, on the other hand, elastic sleeve 12 has elastic restoring force after receiving the external force effect, thereby make the cable also can keep good form under the condition of laying of long distance, be difficult for leading to the poor accumulation of two carrier cable cores 1 length because of hank winding.

Preferably, the profile of the side of the inner sheath 11 in contact with the elastic sheath 12 is circular arc, the cross section of the inner sheath 12 is oblong, and the oblong profile is beneficial to improving the relative winding or bending action of the elastic sheath 12 outside the inner sheath 11 and further improving the anti-torsion action on the two carrier cable cores 1.

As a preferable scheme, referring to fig. 1, a fool-proof protrusion 111 is disposed on one side of the inner sheath 11 corresponding to one of the carrier cable cores 1, so as to help a worker distinguish between two carrier cable cores 1 that are input and returned when the worker plugs the cable.

Referring to fig. 1, the elastic sleeve 12 is provided with a separation belt 4, a reinforcing layer 5 and an outer sheath 6 in sequence. The isolation belt 4 plays a role in protecting the internal cable and facilitating detachment when wire stripping connection is carried out; the reinforcing layer 5 is made of Kevlar fiber, the Kevlar fiber is low in density, high in strength and good in toughness, so that the tensile strength of the cable can be enhanced, particularly for the elastic sleeve 12 which is fragile in a bending or twisting state, the Kevlar reinforcing layer 5 can protect the elastic sleeve 12, and the elastic sleeve 12 can keep good resilience; the outer sheath 6 is the outermost layer of the cable and serves to protect the cable and to insulate it.

As another alternative, referring to fig. 2, the carrier cable dedicated for the power modem further includes two power lines 2 for supplying power, the power lines 2 are disposed in the isolation belt 4 and contact with the outer wall of the elastic sleeve 12, the two power lines 2 contact with the outer wall of the elastic sleeve 12 and are arranged in a distribution manner with a triangular cross section, and the isolation belt 4 tightly wraps the two power lines 2 and the elastic sleeve 12 wrapping the two carrier cable cores 1, so that the position between the cables inside the cable is kept stable.

In addition, a filling material 3 is arranged between the elastic sleeve 12 and the power line 2, the filling material 3 can be filled cotton yarn or filled factice, and the filling material 3 is arranged on the outer sides of the power line 2 and the elastic sleeve 12, so that the position stability of the cable in the cable is better maintained.

The utility model discloses a theory of operation of special carrier cable of power cat does:

through set gradually inner sheath 11 outside two parallel arrangement's carrier cable core 1, elastic sleeve 12, spacer 4, enhancement layer 5 and oversheath 6, inner sheath 11 makes two carrier cable core 1 can keep good parallel state, when the cable receives the hank of external force to wind, spring elastic sleeve 12 can play the effect that the hank of substitute carrier cable core 1 of certain degree was wound or is buckled, thereby make carrier cable lay at long distance and arrange the in-process, also can keep the mutual parallel of two carrier cable cores 1, thereby make two carrier cable cores 1 of signal input and passback length keep unanimous after the cutting into, greatly reduced because of the poor problem of signal that length inconsistent causes, thereby make this special carrier cable of power cat still keep high signal transmission power level under long distance.

The technical solution provided by the present invention is described in detail above, and the principle and the implementation of the present invention are explained by applying specific examples, and the description of the above examples is only used to help understanding the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
