Abstract
The utility model discloses a bow-type drop cable which comprises a protective sleeve. The protective sleeve has an integrated structure which has two circular ends and is connected with a thin narrow belt-shaped connecting belt and has an 8-shaped cross section. Two sides of the protective sleeve are provided with bow-shaped tail wings. A connecting belt of the protective sleeve is provided with an optical fiber which is coated by an insulating layer. Copper wires which are respectively coated by an insulating layer are arranged closely to two sides of the optical fiber. Steel wires which are respectively coated by an insulating layer are arranged outside the copper wires. According to the bow-type drop cable provided by the utility model, the protective cable has the integrated structure which has two circular ends and is connected with the thin narrow belt-shaped connecting belt and has the 8-shaped cross section; the waist part of the protective sleeve, namely the connecting belt is provided with the optical fiber; copper wires which are coated by the insulating layer are arranged adjacently to two sides of the optical fiber; the optical fiber transmits a communication signal; and the copper wires transmit electric energy, thereby integrating the optical cable with the electric cable.
Description
Technical field
The utility model relates to optical cable field, particularly a kind of butterfly leading in cable.
Background technology
Existing butterfly optical cable inside only has an optical fiber purposes that can transmit for signal of communication comparatively single.Simultaneously the main material of optical fiber is quartz material, and when optical fiber can produce dependent variable to optical fiber by the outdoor construction pulling force producing during to indoor introducing, and dependent variable surpasses the serviceable life that will affect greatly optical fiber at 4/1000ths o'clock.Optical fiber is when outdoor construction, and its two ends are fixing, and can to realize optical cable stretching.But after optical fiber introducing is indoor, optical fiber need to be laid along indoor wall curve, therefore needing can be fixing piecemeal by optical fiber, meets the requirement of different indoor environments.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of butterfly leading in cable, its objective is, a kind of transmit communications signals and electric energy are simultaneously provided, and can facilitate the optical cable of indoor laying.
For achieving the above object, the technical solution of the utility model is as follows;
Butterfly leading in cable, it comprises sheath, described sheath is that two ends are rounded and connected and xsect is the integral structure of " 8 " font by the connecting band of thin shaped like narrow, the both sides of sheath are provided with butterfly tail, the connecting band place of sheath arranges the optical fiber that is coated with insulation course, the both sides that are close proximity to optical fiber are provided with the copper cash that is coated with insulation course, and the arranged outside of described copper cash has the steel wire that is coated with insulation course.
Preferably, described sheath is made by low smoke and zero halogen material.
Pass through technique scheme, a kind of butterfly leading in cable that the utility model provides, its sheath is that two ends are rounded and connected and xsect is the integral structure of " 8 " font by the connecting band of thin shaped like narrow, waist at sheath, be that connecting band place arranges optical fiber, optical fiber both sides are near the copper cash that has wrapped up insulation course, Optical Fiber Transmission signal of communication, copper cash electric energy transmitting, is complex as a whole optical cable and cable; Copper wire cloth is placed in to optical cable both sides, because optical cable has higher tensile strength, in work progress, has protected optical cable not to be subject to outside destroy; In sheath both sides, be provided with butterfly tail, only need to be with nail by the fixing fixedly optical cable of empennage, convenient construction during layout.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below.
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
The present embodiment as shown in Figure 1, a kind of butterfly leading in cable, it comprises sheath 1, described sheath 1 is for two ends are rounded and connected and xsect is the integral structure of " 8 " font by the connecting band 2 of thin shaped like narrow, the both sides of sheath 1 are provided with butterfly tail 3, connecting band 2 places of sheath 1 arrange the optical fiber 4 that is coated with insulation course, the both sides that are close proximity to optical fiber 4 are provided with the copper cash 5,6 that is coated with insulation course, the arranged outside of described copper cash 5,6 has the steel wire 7,8 that is coated with insulation course, and described sheath 1 is made by low smoke and zero halogen material.
The present embodiment; the reinforcement that optical fiber both sides steel wire in butterfly optical fiber cable is formed changes solid copper wire into; the all tensile strength of solid copper wire itself have made up the intensity weakness of annealed copper wire, make its existing certain intensity, can protect again optical fiber and carry out the transmission of light signal.
By two hard copper conductors and two thicker wires compound cable or broadband line made together with optical fiber that have insulation course, wherein hard copper conductor and thicker wire are outside with weather resistant fire retardant polyolefin extruded insulation layer.
The utility model becomes butterfly by cable configuration design, and two ends butterfly tail makes in cable laying installation process convenient attractive in appearance, registers one's residence while installing, as long as directly nail empennage, does not need with line card, to fix in addition again.Cable intermediate recess becomes kidney-shaped, is convenient to peel off optical fiber when mounted and does not injure conductor.
For making professional and technical personnel in the field can realize or use the utility model.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize 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.
