the cable core, it is formed by optical fiber ribbon 8 and extrusion molding in the external sheath 9 of optical fiber ribbon, set up in holding the lumen, the optical fiber ribbon is formed by the doubling of many optic fibres, the shape of the cable core matches with holding the lumen, it is fan-shaped in this example, the optical fiber ribbon transmission capacity is large, have certain tensile properties concurrently, the performance, result of use are better, can choose the optical fiber bundle not doubled by resin, there is no reinforcement in the cable core, the flexibility is better, it is easy to stretch out and deform and carry on the construction or change, in the actual production, use the optical fiber ribbon core made in patent No. 201180008860.4, patent name "optical fiber ribbon core, manufacturing approach and optical cable of the optical fiber ribbon core", thinner, lighter, the density is higher;
the card is solid the layer, form by a plurality of backplate 10 interconnect, the one end of backplate forms bellied tenon portion 10a, the other end forms the fourth of the twelve earthly branches portion 10b with tenon portion adaptation, the tenon portion of every backplate and the fourth of the twelve earthly branches portion adaptability joint of adjacent backplate, the setting is outside skeleton and cable core, the backplate has certain radian, protect the cable core through the mode of joint each other, break away from each other for preventing the backplate, the card solid layer still can be fixed around package non-woven fabrics or fine yarn outward.
Although the cable is mainly used in a data center machine room, water-blocking ointment or water-blocking yarns are filled between the sheath and the optical fiber ribbon in consideration of special conditions such as water seepage of the machine room.
The electric lead and the cable core are arranged in the same framework, and a plurality of servers can be connected only by once wiring and multiple branching, so that the laying workload of the optical cable is greatly reduced, and manpower and material resources are saved.
For preventing that the cable core from rocking in the holding intracavity, improve its stability, the left and right sides that supports the arris is equipped with recessed recess 61, and the recess is preferred to be established near the middle part that supports the arris, and the left and right sides of fan-shaped sheath is equipped with the arch 21 with the recess adaptation, and when the installation cable core, only need with two protruding embedding left and right sides of sheath support in the relative recess of arris, can realize the fixed of cable core.
Further, as shown in fig. 1-3, chamfers 11 are arranged on two sides of each supporting edge close to the outer end, two J-shaped hook portions 12 are arranged on the inner side of each guard plate, each hook portion is composed of a straight portion 12a and an arc portion 12b, the arc portions are clamped with the chamfers of the adjacent supporting edges, the guard plates and the two adjacent supporting edges are fixed, and firmness and tightness of the guard plate clamping are greatly improved through matching of the hook portions and the chamfers.
Further, the inboard of every backplate, be provided with inside arch between two hook portions, elastic component 13 with the sheath butt, when cable core embedding holding chamber, backplate block back, elastic component or deformation butt are on the sheath, the inward extrusion sheath of elastic component, it is more firm to make the cable core, the sheath gives the outside effort that the elastic component is opposite simultaneously, make the backplate present the trend of outside deformation, make hook portion and chamfer joint tighter, the overall structure of optical cable is more firm, in the embodiment, the elastic component is equipped with two, its inside is equipped with along axial cavity 13a, inside is the cavity form, more help the deformation of elastic component.
In addition, the outer side of the sheath and the surface opposite to the inner side of the guard plate are provided with pulling parts 14 at even intervals along the axial direction, the pulling parts are in an arc shape with a hollow part protruding outwards and are abutted between the two elastic pieces, and when the cable core is replaced, the arrangement of the pulling parts is more beneficial to pulling the cable core out of the framework.
The elastic piece and the lifting part are arranged to be hollow, and the effects of shock absorption and pressure resistance can also be achieved.
When the cable core is damaged, in order to facilitate replacement of the cable core, as shown in fig. 4 and 5, radial hole columns 15 are arranged inside each supporting edge, the hole columns are uniformly arranged at intervals in the axial direction of the cable, the length beta of each hole column is larger than or equal to the length alpha of the groove from the outer end face of the supporting edge where the groove is located, when the cable core is replaced, a tool such as a screwdriver 16 is inserted into the hole, a screwdriver handle is rotated in the direction opposite to the position of the cable core, the protrusion of the screwdriver handle is separated from the groove, and the cable core is pulled out.
In actual operation, it is found that when only a single radial hole column is arranged inside the supporting edge, the rotation of the screwdriver handle can easily cause the other cable core adjacent to the supporting edge to be separated from the groove, and through further optimization, two hole columns are arranged along the radial direction, when a certain cable core adjacent to the supporting edge needs to be replaced, the screwdriver is inserted into the hole column adjacent to the certain cable core, as shown in fig. 6, when the cable core at the position A needs to be replaced, the screwdriver is inserted into the hole column C and the handle is rotated to the left side, so that the cable core at the position A can be separated from the corresponding supporting edge, after the replacement is finished, a new cable core is only required to be placed into the accommodating cavity again, and after the new cable core is clamped with the corresponding groove, the external protection plate is installed again, so that the operation is simple and convenient.
