Description of drawings

Fig. 1 is a schematic cross-sectional view of a steel wire stranded stainless steel tube miniature optical cable of the present invention.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

The reference numerals in Fig. 1 are: sheath 1; twisted steel wire 2; stainless steel tube 3; filling ointment 4; optical fiber 5.

As shown in Figure 1, a steel wire stranded stainless steel tube miniature optical cable includes a sheath 1, a stranded steel wire 2, a stainless steel tube 3, a filling ointment 4 and an optical fiber 5, wherein the sheath 1 wraps the stranded Steel wire 2, the stranded steel wire 2 wraps the stainless steel tube 3, the stainless steel tube 3 wraps the filling ointment 4, and the filling ointment 4 wraps the optical fiber 5.

As shown in Figure 1, the material of the sheath 1 can be selected from PE, TPU, nylon, LSZH, PVC and other materials with different characteristics according to different application requirements. The sheath 1 is used to protect the stranded steel wire 2 and print the cable identification.

As shown in Figure 1, the material of the stranded steel wire 2 can be selected from ordinary steel wire, phosphating steel wire, galvanized steel wire or stainless steel wire according to different application requirements, and the number of stranded steel wires is not less than 12 to reduce the outer diameter of the optical cable. The role of the steel wire 2 is to improve the bending resistance of the inner stainless steel tube 3, increase the tensile strength of the optical cable, and enhance the lateral pressure resistance of the optical cable.

As shown in FIG. 1 , the material of the stainless steel pipe 3 can be 304, 316 stainless steel or other alloy materials according to different application occasions. The outer diameter of the stainless steel tube 3 can be selected from 0.9 mm to 3.2 mm according to the number of cores of the optical fiber 5 ranging from 1 to 48 cores; the stainless steel tube 3 provides good protection for the optical fiber 5 .

As shown in FIG. 1 , the filling ointment 4 can be selected from common ointment, low-temperature ointment or high-temperature ointment according to different application occasions. Its function is to form a buffer layer between the optical fiber 5 and the stainless steel tube 3 to protect the optical fiber 5 better.

As shown in FIG. 1 , different types of optical fibers can be selected according to different application requirements.

As shown in Figure 1, the utility model provides a steel wire stranded stainless steel tube micro-optical cable. The micro-optic cable depends on the number of cores, and the outer diameter of the product is 2.5mm (1 core) to 7mm (48 cores). The alternative model is GYTS , GYTA conventional optical cable. Compared with GYTS and GYTA conventional optical cables with the same number of cores, the outer diameter of the optical cable is smaller and the weight is lighter.

The above content is a further detailed description of the utility model in combination with specific preferred embodiments, and it cannot be assumed that the specific implementation of the utility model is only limited to these descriptions. For a person of ordinary skill in the technical field to which the utility model belongs, without departing from the concept of the utility model, some simple deduction or substitutions can also be made, which should be regarded as belonging to the protection scope of the utility model.
