Abstract
The utility model discloses a butterfly-shaped drop cable and a sheath thereof. The sheath of the butterfly-shaped drop cable comprises an optical fiber containing hole and tearing gaps, wherein each tearing gap is triangular and the inward concave direction of each tearing gap faces to the optical fiber containing hole; and two angles of more than 0 degree are respectively formed between the inward concave direction of each tearing gap toward the optical fiber containing hole and two symmetrical center lines of the cross section of the sheath of the butterfly-shaped drop cable. As each tearing gap is triangular and the inward concave direction of each tearing gap faces to the optical fiber containing hole, the sheath can be straightly torn from any one of the tearing gaps to the optical fiber containing hole, so that optical fibers can be conveniently taken out; and simultaneously, the tearing gaps obliquely face to the optical fiber containing hole relative to the symmetrical center lines of the cross section of the sheath of the butterfly-shaped drop cable, so that the thickness of a middle sheath skin is not reduced, the optical fibers cannot be bitten off by cicadas easily, tearing is not affected when the optical fibers are taken out, and the reliability of the sheath is improved.

Embodiment
The utility model embodiment provides a kind of butterfly leading in cable sheath, to increase the reliability of sheath.The utility model also provides a kind of butterfly leading in cable that comprises above-mentioned butterfly leading in cable sheath.
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1 and Fig. 2, the structural representation of the butterfly leading in cable sheath that Fig. 1 provides for the utility model embodiment; The structural representation that the tearing port of the butterfly leading in cable sheath that Fig. 2 provides for the utility model embodiment distributes.
The butterfly leading in cable sheath that the utility model embodiment provides, comprise optical fiber accommodation hole and tearing port 2, tearing port 2 is the triangle tearing port, the indent direction of tearing port 2 is towards optical fiber accommodation hole 1, tearing port 2 indents have angle to two symmetrical center line of the xsect of the direction of optical fiber accommodation hole 1 and butterfly leading in cable sheath, and this angle is greater than 0 °.
Dotted line in Fig. 2 is two symmetrical center line of the xsect of butterfly leading in cable sheath.
wherein, tearing port 2 is the triangle tearing port, the indent direction of tearing port 2 is towards optical fiber accommodation hole 1, when tearing so, can tear optical fiber accommodation hole 1 by tearing mouth 2 always, be convenient to the taking-up of optical fiber, simultaneously, tearing port 2 indents have angle to two symmetrical center line of the xsect of the direction of optical fiber accommodation hole 1 and butterfly leading in cable sheath, angle is greater than 0 °, that is to say tearing port 2 with respect to the symmetrical center line of the xsect of butterfly leading in cable sheath be tilt towards optical fiber accommodation hole 1, can not weaken the sheath skin thickness of center section, optical fiber is difficult for being bitten broken by cicada, and do not affect and tear taking-up optical fiber, increased the reliability of sheath.
Simultaneously, the indent direction of tearing port 2 is when this tearing port 2 is torn towards optical fiber accommodation hole 1 Main Function, can tear optical fiber accommodation hole 1 always, makes the optical fiber in optical fiber accommodation hole 1 to be removed.
And, from Fig. 3, we can find out, the both sides that are arranged on optical fiber accommodation hole 1 due to tearing port 2 symmetries, but also be on the less direction of the width of existing butterfly leading in cable sheath, very easily tear so, easily bite broken, and the tearing port 2 in the butterfly leading in cable sheath that the utility model embodiment provides tilts towards optical fiber accommodation hole 1, width that can this sheath of attenuate.
Concrete, tearing port 2 is two, and tears 2 mouthfuls of indents to the center of circle of the straight line process optical fiber accommodation hole 1 of the summit composition of optical fiber accommodation hole 1.Two tearing ports 2 are set help tearing fully of sheath, facilitate the taking-up of optical fiber, when tearing, tear since a tearing port 2, then, tear optical fiber accommodation hole 1, because one of them tearing port 2 indent is passed through the center of circle of optical fiber accommodation hole 1 to summit and another tearing port 2 indents of optical fiber accommodation hole 1 to the straight line of the summit composition of optical fiber accommodation hole 1, after optical fiber accommodation hole 1 is torn, be easy to tear another one tearing port 2, thereby sheath is torn fully so, be convenient to take out optical fiber, simultaneously, first tear which tearing port 2 can, very convenient.
and, the position of these two tearing ports 2 is asymmetric with respect to two symmetrical center line of the xsect of sheath, as can be seen from Figure 3, butterfly leading in cable sheath of the prior art is quadrilateral, pass so in the straight line of optical fiber accommodation hole 1, two symmetrical center line with the xsect of sheath are the shortest, if these two tearing ports 2 are symmetrical in wherein symmetrical center line, be arranged on sheath, these two tearing ports 2 will inevitably be on another symmetrical center line so, and shorten the length of this symmetrical center line, more shortened the thickness of sheath on symmetrical center line, easily break by the teeth, and the tearing port 2 of the butterfly leading in cable sheath that the utility model embodiment provides with respect to the symmetrical center line of the xsect of butterfly leading in cable sheath be tilt towards optical fiber accommodation hole 1, can not weaken simultaneously the thickness on the straight line of the butterfly leading in cable sheath that the utility model embodiment provides, also can increase the reliability of sheath.
Concrete, the both sides up and down of optical fiber accommodation hole 1 are provided with reinforcement accommodation hole 3.Can insert reinforcement in reinforcement accommodation hole 3, the butterfly leading in cable sheath that the utility model embodiment provides is reinforced.
Concrete, the both sides up and down that are arranged on optical fiber accommodation hole 1 of reinforcement accommodation hole 3 symmetries.Consolidation effect is better.
The utility model embodiment also provides a kind of butterfly leading in cable, comprises optical fiber and sheath, and sheath is butterfly leading in cable sheath as described in above-mentioned any one embodiment.
This butterfly leading in cable does not weaken the sheath skin thickness of center section, is difficult for being bitten broken, and does not affect to tear and take out the reliability that optical fiber has increased the use of the reliability of sheath and this butterfly leading in cable.
Concrete, the butterfly leading in cable also comprises the reinforcement that is arranged in sheath.In order to reinforce the butterfly leading in cable.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, realization in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
