Abstract
The utility model discloses a photoelectric composite cable, which belongs to the technical field of electric wires and cables. The photoelectric composite cable comprises a cable core, an embossed metal pipe and an outer jacket, wherein the embossed metal pipe is positioned outside the cable core; the outer jacket is positioned outside the embossed metal pipe; and the cable core comprises at least one pair of leads which is coated with an insulating layer respectively and at least one optical fiber which is accommodated in an optical fiber casing. The photoelectric composite cable is characterized in that: a reinforcing fiber which follows the optical fiber is also accommodated in the optical fiber casing. In the technical scheme, the reinforcing fiber is arranged in the optical fiber casing which accommodates the optical fiber, so that the reinforcing fiber independently enhances the tensile strength of the optical fiber and remarkably improves the overall tensile strength of a cable body; moreover, the optical fiber is protected by the reinforcing fiber in each optical fiber casing, so that the phenomenon of the overall damage caused by the damage of a single part in the prior art is avoided.
Description
Technical field
The utility model belongs to technical field of electric wires and cables, is specifically related to a kind of optoelectronic composite cable.
Background technology
The situation of laying of optoelectronic composite cable roughly has following three kinds, and the one, flat formation; The 2nd, level is built on stilts lays; The 3rd, vertical run.Flat formation is less relatively to the pulling force of the optical fiber of optoelectronic composite cable, and level is built on stilts lays then and need protect support or cable tie by means of holder, self-bearing type is built on stilts lay then the requirement of the tensile strength of optoelectronic composite cable the highest.Self-bearing type is built on stilts to be laid main but is used for communication base station, intelligent grid and skyscraper (people claim that skyscraper is a high building) etc. with being not limited to.
Technical scheme such as the novel license notification number of practicality CN201584220Y (a kind of line optoelectronic composite cable that drags) around the tensile strength of improving optoelectronic composite cable; this optoelectronic composite cable is to set gradually stainless steel flexible hose outside the polyester band outside being paperwrapped in cable core; aramid fiber stranded layer and polyurethane jacket; play the effect that increases tensile strength by outermost polyurethane jacket and the aramid fiber stranded layer between stainless steel flexible hose and polyurethane jacket; but make such optoelectronic composite cable except exist complex structure and manufacture craft tediously long; also there is protection effect shortcoming to optical fiber; because what patent structure adopted is the integral type protection; so; in case the aramid fiber stranded layer and/or the stainless steel flexible hose that shield cause damage; all conductor wire cores and optical fiber in the cable core are affected, the situation of injuring all promptly occurs.There are aforesaid shortcoming equally in a kind of electro-optic compound cable for towing and manufacture method thereof that publication No. CN101714425A (being same applicant's application of CN201584220Y) provides.
The tensile strength that how improves the optoelectronic composite cable that is applied to the occasion such as communication base station, intelligent grid and skyscraper that the applicant mentions in the above effectively is that industry is paid close attention to and the phase is got the technical problem of solution all the time, yet there is no all corresponding techniques enlightenments that has in disclosed patent documentation and non-patent literature.For this reason, the applicant has carried out good try, and technical scheme described below is based on producing under this prerequisite.
Summary of the invention
Task of the present utility model is to provide a kind of and can be have effectively not only promoted the protection of optical fiber but also improve optoelectronic composite cable to the whole tensile strength of cable body.
Task of the present utility model is finished like this, a kind of optoelectronic composite cable, comprise cable core, embossing metal tube and oversheath, the embossing metal tube is positioned at outside the cable core, oversheath is positioned at outside the embossing metal tube, described cable core comprises at least one pair of lead and at least one optical fiber that is contained in the ferrule that is coated with insulating barrier separately, is characterised in that: also accommodate the fortifying fibre that is used to follow described optical fiber in the described ferrule.
Insulating barrier described in the utility model also is provided with crowded sheath outward.
Ferrule described in the utility model also has additional the casing protection layer outward.
Fortifying fibre described in the utility model is an aramid fiber, and described optical fiber is positioned at the central authorities of aramid fiber.
Embossing metal tube described in the utility model is a stainless steel tube.
The technical scheme that the utility model provides is owing to set up fortifying fibre in the ferrule of receiving optical fiber, thereby both played the effect that individually optical fiber is increased tensile strength by fortifying fibre, significantly improve with tensile strength again the integral body of cable body, by the fortifying fibre in each ferrule optical fiber is takeed good care of, the such phenomenon of injuring all of prior art can not occurred.
Description of drawings
Fig. 1 is the first example structure figure of the present utility model.
Fig. 2 is the second example structure figure of the present utility model.
Embodiment
Embodiment 1:
Ask for an interview Fig. 1, the cable core 1 that provides has couple of conductor 11, and each lead 11 is outer to be squeezed and cover (lining) insulating barrier 111 is arranged, and crowdedly insulating barrier 111 outside is covered with crowded sheath 1111.Aforesaid insulating barrier 111 and crowded sheath 1111 all preferably use low smoke and zero halogen cross-linked polyolefin or low smoke and zero halogen non-crosslinked polyolefin or rubber composition.The cable core 1 that provides also has a pair of optical fiber 12, and each optical fiber 12 is contained in the ferrule 121, and is coated with casing protection layer 1211 outside ferrule 12, and the material of casing protection layer 1211 is with the description to insulating barrier 111 and crowded sheath 1111.
As technical essential of the present utility model, in aforesaid ferrule 121, also accommodate fortifying fibre 122, fortifying fibre 122 is around optical fiber 12, and promptly optical fiber 12 is positioned at the central authorities of fortifying fibre 122.Fortifying fibre 122 is preferred to adopt aramid fibers, but also can use other fiber with the aramid fiber equivalence.
Embossing metal tube 2 is set outside cable core 1, and embossing metal tube 2 is a stainless steel tube, squeezes outside embossing metal tube 2 and covers oversheath 3, and the material of oversheath 3 is as the description to insulating barrier 111 and squeeze jacket 1111.
Embodiment 2:
Ask for an interview Fig. 2, the cable core 1 that provides has three pairs of leads 11 (every pair has two leads 11) and has three pairs of optical fiber 12 (every pair has two), and all the other are all with the description to embodiment 1.
By the foregoing description 1 and 2 as can be known, the radical that constitutes the logarithm of lead 11 of cable core 1 and optical fiber 12 is as required and changeable, thereby the quantity of the embodiment that can not provide with the applicant limits the utility model scheme.
