In order to make the objects, features and advantages of the present invention more comprehensible, the technical solutions in the embodiments of the present invention are described in detail below with reference to the accompanying drawings, and it is apparent that the embodiments described below are only some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The technical scheme of the invention is further described below by the specific embodiments with reference to the accompanying drawings.
Referring to fig. 1-2, the present invention provides a technical solution:
A butterfly-type optical cable comprising: the outer sheath 2, first light unit 3, second light unit 4, the transversal symmetry's of oversheath 2 dagger shape that personally submits, oversheath 2 includes top 21, terminal 24, first arc 22 and second arc 23, first arc 22 with second arc 23 are two sections, top 21 is circular and connects first arc 22, first arc 22 links to each other with second arc 23, the arc of first arc 22 is inwards sunken, the arc of second arc 23 outwards protrudes, and two sections second arc 23 intersects to form sharp angle shape's terminal 24, first light unit 3 with second light unit 4 imbeds in proper order in oversheath 2, first light unit 3 yuan imbeds two sections in oversheath 2 the region between first arc 22, second light unit 4 yuan imbeds two sections in oversheath 2 the region between second arc 23, top 21 inside is equipped with first reinforcement 1.
The first light unit 3 and the second light unit 4 are sequentially embedded into the outer sheath 2, and when in use, the two light units can be independently constructed according to different application scenes after being peeled from the tearing opening of the outer sheath 2.
The first light unit 3 is a butterfly light unit, the second light unit 4 is a circular light unit, and the cross-sectional area of the second light unit 4 is larger than that of the first light unit 3, so that in order to ensure enough strength, the lower half of the outer sheath 2 is relatively larger in size, and therefore, the second arc section 23 is provided with a proper protruding structure in the horizontal direction to ensure certain strength of the outer sheath 2.
The whole structure of the outer sheath 2 is in a slender dagger shape, which makes rainwater, worm eggs and corrosive liquid difficult to accumulate or adhere on the surface of the optical cable, and even if the liquid drifts on the butterfly-shaped optical cable, the liquid can easily slide down immediately; the smaller the included angle θ between the tangent line at a certain point of the first arc segment 22 and the second arc segment 23 and the horizontal line, i.e. the flatter the gradient is, the larger the supporting force of the liquid such as rainwater from the outer sheath 2 can be obtained, the larger the friction force between the two is, and the rainwater is less likely to slide down; on the contrary, the larger the included angle theta between the tangent line at a certain point and the horizontal line is, i.e. the steeper the gradient is, the smaller the supporting force from the outer sheath 2 can be obtained by the liquid such as rainwater, the smaller the friction force between the two is, the liquid such as rainwater is easy to slide down, when the included angle theta is more than or equal to 90 degrees, the liquid such as rainwater loses the supporting force from the outer sheath 2, and the liquid can slide down rapidly under the action of gravity, and the scheme has the design that the first arc section 22 is concave and the second arc section 23 is convex instead of directly designing the outer sheath 2 into an oval shape, so that: the included angle theta between the tangent line and the horizontal line at a certain point of the area of the upper half part of the ellipse is smaller than 90 degrees, and the area provides relatively large adhesion supporting force for liquids such as rainwater, so that the area where the liquids such as rainwater are accumulated is reduced by shortening the length of the corresponding arc section with the included angle theta smaller than 90 degrees as much as possible.
Further, the first arc section 22 and the second arc section 23 are arranged tangentially, so that the junction between the two arc sections is more smooth and smoother through the tangential arrangement, and the occurrence of structures such as edges and corners or steps is avoided to produce a reserved space for liquid such as rainwater.
When the liquid such as rainwater falls in the concave of the first arc section 22, because the included angle θ of this area is greater than 90 °, the liquid such as rainwater loses the supporting force from the outer sheath 2, i.e. the base of the loss of adhesion inevitably flows downwards, the included angle θ of the tangent line of the first arc section 22 and the second arc section 23 is set to be greater than 80 °, when the rainwater flows nearby, because the length of the nearby arc section is shorter and the included angle θ is greater than 80 °, i.e. the gradient is still steeper, the liquid such as rainwater can obtain the supporting force and friction force of the outer sheath 2, so that the liquid such as rainwater cannot stably adhere to this area, the included angle θ of the middle part of the second arc section 23 approaches 90 °, the included angle θ of the lower part of the second arc section 23 is greater than 90 °, and the liquid such as rainwater cannot provide sufficient adhesion, so that the liquid such as rainwater can rapidly slide.
Further, the difference between the lowest point of the first arc section 22 in the horizontal direction and the highest point of the second arc section 23 in the horizontal direction is less than or equal to 2mm, and if the difference is too large, the first arc section 22 and/or the second arc section 23 form a transition section with a longer length and a flatter gradient, and the transition section may provide an adhesion foundation for liquids such as rainwater, so that the size is limited to avoid the accumulation of rainwater at the transition section or the corner of the first arc section 22 and the second arc section 23.
In summary, the above-mentioned structure setting of oversheath 2 makes in time the landing in the adhesion of appearance rainwater or corrosive liquids etc. on the optical cable surface, avoids causing liquids such as rainwater to be stocked on the optical cable surface, leads to increasing the heavy burden and the atress of optical cable and to the damage such as optical cable corrosion, guarantees the good signal transmission of optical cable.

A suspension wire 25 is further arranged on the outer sheath 2 in the area between the first reinforcement 1 and the first light unit 3, and the suspension wire 25 is wider than a butterfly-shaped optical cable with a conventional shape, has good bearing effect and is not easy to damage.
Further, the end 24 of the outer sheath 2 is provided with a second reinforcing member 6, the weight of the second reinforcing member 6 is smaller than that of the first reinforcing member 1, the tensile property of the optical cable can be integrally increased, the load bearing burden of the hanging wire 25 is reduced, good signal transmission of the optical cable is guaranteed, and the second reinforcing member 6 can be made of aramid fiber, glass fiber yarn or other materials.
Further, the first light unit 3 and the second light unit 4 are both internally provided with third reinforcing members 7, the third reinforcing members 7 enable the first light unit 3 and the second light unit 4 to have a certain tensile strength, good signal transmission of an optical cable is further guaranteed, the two light units can be independently constructed after being stripped, and materials of the third reinforcing members 7 can be selected from steel wires, steel strands, aramid fibers, aramid fiber plastic rods, glass fiber rods and the like.
