In order to solve the technical problem, the utility model discloses a following technical scheme: the utility model provides a novel one-piece type indoor optical cable, includes coated optical fiber and sheath, the sheath cover is established in coated optical fiber's outside, is equipped with aramid yarn reinforcing element between coated optical fiber and the sheath, coated optical fiber and aramid yarn reinforcing element fixed connection.
The coated optical fiber and the aramid yarn reinforcing element are adhesively connected by an adhesive body.
The adherend is a resin adherend.
The resin adherend is a gel structure made of acrylate.
The coated optical fiber comprises a fiber core, and a coating layer is wrapped outside the fiber core.
The sheath is a tubular structure made of polyvinyl chloride, low-smoke halogen-free flame-retardant polyolefin, polyethylene or nylon.
Adopt above-mentioned structure the utility model discloses, through adopting the resin bonding body, it is together fixed with coated optical fiber and aramid yarn reinforcing element to the form of a body structure is stereotyped through the mould, and through ultraviolet lamp curing oven solidification shaping, then establish the one deck sheath at its outside cover, make sheath and coated optical fiber and aramid yarn reinforcing element's fit tightly hug closely together, realize with the machine case rack in same space of littleer optical cable size, the wiring of bigger core number is carried out to the network computer lab, and the mechanical properties of optic fibre, environmental performance etc. has obtained higher embodiment.

Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1 is a coated optical fiber, 2 is a sheath, 3 is an aramid yarn reinforcing member, and 4 is a resin binder.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
As shown in fig. 1, the utility model provides a novel one-piece type indoor optical cable, including coated optical fiber 1 and sheath 2, specifically for coated optical fiber 1 includes the fibre core, and the outside parcel of fibre core has the coating, and the coating can keep the propagation of light in the fibre core, and 2 covers of sheath are established in coated optical fiber 1's outside to play the effect of protection to coated optical fiber 1. An aramid yarn reinforcing element 3 is arranged between the coated optical fiber 1 and the sheath 2, the sheath 2 and the aramid yarn reinforcing element 3 are both used for protecting the coated optical fiber 1, providing mechanical strength required by cable bearing, laying, storage, transportation and use, preventing invasion of moisture and water, environmental erosion, chemical erosion, organism gnawing and the like, and improving the application performance of the optical cable.
The coated optical fiber 1 and the aramid yarn reinforcing element 3 are fixedly connected, specifically, the coated optical fiber 1 and the aramid yarn reinforcing element 3 are bonded and connected through a bonding body, and preferably, the bonding body is a resin bonding body 4, so that the processing environment of the optical cable is adapted, and the bonding effect of the coated optical fiber 1 and the aramid yarn reinforcing element 3 is good. The coated optical fiber 1 and the aramid yarn reinforcing element 3 are fixed together by the resin adhesive body 4, are shaped in an integrated structure mode through a die and are cured and molded through an ultraviolet lamp curing oven, and then the sheath 2 is extruded and molded through the die and is firmly attached to the outside of the combined body of the coated optical fiber 1 and the aramid yarn reinforcing element 3. The common single-core indoor optical cable mainly comprises a tightly sleeved optical fiber, an aramid yarn reinforcing element and a sheath, wherein the 3 parts are completely loosened, and the tightly sleeved optical fiber, the aramid yarn reinforcing element and the sheath easily slide relative to each other in the using process to influence the using effect; in addition, since the tight-buffered optical fiber includes the coated optical fiber and the tight-buffered coating layer, the overall outer diameter of the optical cable is large, and the maximum number of cores cannot be distributed in a limited space.
Coating optical fiber 1 and aramid yarn reinforcing element 3 are fixed together through resin binder 4, through the mould design with the form of a body structure, then with the laminating of sheath 2 firmly in the outside of coating optical fiber 1 and aramid yarn reinforcing element 3's complex, make coating optical fiber 1, there are not tight cover coating layer and unnecessary space in the middle of sheath 2 and aramid yarn reinforcing element 3, realize the great reduction of whole external diameter of optical cable, thereby can realize the wiring of more core number with the quick-witted case rack in same space with littleer optical cable size, network machine room, and aramid yarn reinforcing element 3 of optical cable still keeps the same quantity, the mechanical properties of optic fibre has been guaranteed, environmental performance etc.
The resin adhesive body 4 in this embodiment is a gel structure made of acrylate, the sheath 2 is a tubular structure made of polyvinyl chloride, low-smoke halogen-free flame-retardant polyolefin, polyethylene or nylon, and the materials for making the resin adhesive body 4 and the sheath 2 are not limited to the above materials, and other suitable materials capable of realizing the embodiment can be selected.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
