Description

Technical Field

[0001] The present invention belongs to the field of optical cables, and particularly relates to a multi-unit butterfly-shaped fiber optic cable with composite components. Background Art

[0002] With the popularization and application of FTTH, FTTR, and FTTC, the use of butterfly-shaped fiber optic cables is increasing day by day. Since different users on the same floor require different butterfly-shaped fiber optic cables, it is often necessary to lay them multiple times, resulting in an increase in cost.

[0003] CN115097588A discloses a multi-unit butterfly-shaped fiber optic cable, which has multiple butterfly units and multiple engaging components; the butterfly unit is composed of an optical fiber, a strengthening member, and a unit sheath, and the unit sheath has a first engaging port and a second engaging port; the engaging component is composed of an engaging body; in the assembled state, the outer edges of all the butterfly units are on the same cylindrical surface, one end of the engaging component between adjacent butterfly units is embedded in the second engaging port of one butterfly unit, and the other end of the engaging component between adjacent butterfly units is embedded in the first engaging port of another butterfly unit. It has the advantages of being convenient for expanding butterfly units, flexible and convenient to assemble, having a compact structure, small occupied space, less material consumption, and low cost.

[0004] However, for the structure of the prior art, although it can be expanded by the engagement of butterfly units and engaging components, when a large number of butterfly units are required, the assembly speed is slow and the structural stability after assembly is poor; since the ends in the length direction of the cross-section of the butterfly introduction unit are engaged by components, the size of the formed optical cable is large, the space in the central space is large and the stability is poor, and it will spread even with a slight touch, which limits its use. Summary of the Invention

[0005] To solve the above problems, the object of the present invention is to disclose a multi-unit butterfly-shaped fiber optic cable with composite components, which is realized by the following technical solutions.

[0006] A multi-unit butterfly-shaped fiber optic cable with a composite component, having a composite component which is an integral structure; the composite component consists of m connecting bars and n butterfly units, where m ≥ 3, n ≥ 2, and both m and n are integers; each butterfly unit consists of two reinforcing members, an optical communication component, and a butterfly sheath, the two reinforcing members are respectively located on the upper and lower sides of the optical communication component, the butterfly sheath integrally covers the reinforcing members and the optical communication component, the cross-section of the butterfly sheath is a runway shape or a rectangle, and the optical communication component is located in the center of the butterfly sheath; on the outer edges of the left and right sides of each butterfly sheath, there is a connecting bar connected, the space above the connecting bar is the second groove, and the space below the connecting bar is the first groove; the cross-section of the composite component is in a row structure, all the connecting bars are on the same straight line, all the butterfly units are arranged in parallel, and the left-right symmetry plane of each butterfly sheath is perpendicular to the connecting bar; the up-down symmetry planes of all the connecting bars are in the same plane, and each butterfly unit is symmetric about the up-down symmetry plane of the connecting bar.

[0007] A multi-unit butterfly-shaped fiber optic cable with a composite component, having a plurality of the above-mentioned composite components, and the plurality of composite components are distributed in a stacked manner. Between the upper and lower adjacent composite components: the butterfly sheath of the upper composite component located below the connecting bar is embedded in the second groove of the lower composite component, and the butterfly sheath of the lower composite component located above the connecting bar is embedded in the first groove of the upper composite component, and all the composite components are fitted together to form an integral body.

[0008] In this solution, a second groove is also formed above the outermost connecting bar, and a first groove is also formed below the outermost connecting bar; when there is an outermost connecting bar, it plays a role in supporting the corresponding butterfly sheath, but if the outermost connecting bar does not exist, since the single composite component is an integral structure, the middle connecting bar can also support and bear the weight of the edge butterfly units.

[0009] A multi-unit butterfly-shaped fiber optic cable with a composite component, having one of the above-mentioned composite components, and the outermost connecting bars of the composite component are bonded to form a closed circular structure, all the connecting bars are on the first circumference, all the butterfly units are arranged in a circle, the left-right symmetry plane of each butterfly sheath passes through the center of the first circumference, the top of the inner butterfly sheath is on the second circumference, the inner space surrounded by the second circumference is the central cavity, the central cavity is communicated with the first groove, and the cross-section of the composite component is in a circular structure.

[0010] A multi-unit butterfly-shaped fiber optic cable with composite components, having multiple identical composite components as described above, or having X first composite components and Y second composite components, where X and Y are both natural numbers; X and Y cannot be 0 at the same time; the first composite component and the second composite component are both the composite components as described above. In the first composite component, m = 4 and n = 3. In the second composite component, m = 3 and n = 2; all the composite components are joined and bonded to form a closed circular structure. All the connecting bars are on the first circumference, and all the butterfly units are arranged in a circular pattern. The left-right symmetry plane of each butterfly sheath passes through the center of the first circumference. The top of the inner butterfly sheath is on the second circumference. The inner space enclosed by the second circumference is the central cavity. The central cavity is connected to the first groove. The cross-section of the composite component is a circular structure.

[0011] The combination of the above first composite component and second composite component can form any multi-unit structure with more than 1 butterfly unit. Moreover, there are at most two types of composite components, making production, storage quite convenient and assembly flexible. Of course, for specific usage scenarios, it is not limited to the above first composite component and second composite component, that is, the values of m and n can be adjusted as needed.

[0012] In the above-mentioned multi-unit butterfly-shaped fiber optic cable with composite components, a support component is provided in the central cavity. The support component is composed of a reinforcing member, a cushion layer, at least three support members, and a telescopic layer. The cushion layer is wrapped around the reinforcing member. The support members are symmetrically distributed outside the cushion layer. One end of the support member is connected to the outer surface of the cushion layer. The telescopic layer is located outside the support member. The other end of the support member is connected to the inner surface of the telescopic layer; the outer surface of the telescopic layer and the butterfly sheath of each butterfly unit are in line contact, and the so-called line contact is a tangential line contact.

[0013] The function of the support component is to support and position the composite component, making the structure more stable. In fact, even when it is not present, it can also play the role of optical cable transmission. The above support members are symmetrically distributed outside the cushion layer. The support members can be straight elements or curved elements, as long as they have a certain strength and hardness, or have a certain strength and hardness under specific conditions. For example, when the support member is inflated inside, it has a certain strength and hardness, etc. Another example is that it is an elastic element; the telescopic layer has a large deformation function, high elasticity and elastic recovery performance, such as materials similar to balloon bodies or polyurethane materials, etc.; when gas is filled between the cushion layer and the telescopic layer, the telescopic layer deforms, enlarges, and expands. When maintaining a certain specific pressure, it deforms, enlarges, and expands to a certain diameter; at different pressures, it can present different diameters. In this way, it can adapt to the structures of different numbers of butterfly units, and it can also make the butterfly units in the optical cable change as needed, achieving the purpose of flexible use and flexible assembly.

[0014] This application has the following main beneficial technical effects: simple structure, easy to assemble, better mechanical properties, significantly reduced cable size, more stable structure, more reliable, and more convenient and flexible to use. BRIEF DESCRIPTION OF THE DRAWINGS

The difference is that in the formed fiber optic cable, the composite component 1 is composed of eight connecting strips 11 and eight butterfly units 12; there is no support component 2.

[0033] In addition, in this embodiment, it can be formed by splicing two composite components 1. When splicing, the splicing part is bonded so that the two composite components 1 are combined into one body and form a complete first cylindrical structure; among them, each composite component 1 only has five connecting strips 11 and four butterfly units 12; among them, the length of the outermost connecting strip 11 is preferably half of the length of the middle connecting strip 11.

[0037] In this embodiment, the upper ends of the butterfly sheaths 123 of all butterfly units 12 are in the same plane; the lower ends of the butterfly sheaths 123 of all butterfly units 12 are in the same plane.

[0038] Embodiment 4: Please refer to Figure 9 , and refer to Figures 7 to 8, A multi-unit butterfly-shaped optical cable with composite components is composed of the composite components 1 described in Example 3. The composite components 1 are stacked with vertical displacement. The butterfly-shaped sheath of the upper composite component 1 abuts on the first groove of the lower composite component 1. The butterfly-shaped sheath of the upper composite component 1 is not embedded in the first groove of the lower composite component 1, but is adhered to the butterfly-shaped sheath of the lower composite component 1, and all the composite components 1 form an integral whole.

[0039] Of course, in this embodiment, the number of composite components 1 is not limited to five, and can also be other numbers to form a multi-layer stack.

[0040] Example 5: Please refer to Figure 10 , and refer to Figures 7 to 9 , A multi-unit butterfly-shaped optical cable with composite components, referring to Example 4, the difference is that it has three composite components 1; the number of connection bars 11 and butterfly units 12 in each composite component 1 is different from that in Example 4; the cross-section of the butterfly-shaped sheath 123 is rectangular; in adjacent upper and lower composite components, the butterfly-shaped sheath 123 of the upper composite component 1 located below the connection bar 11 is embedded in the second groove of the lower composite component 1, and the butterfly-shaped sheath 123 of the lower composite component 1 located above the connection bar 11 is embedded in the first groove of the upper composite component 1; when the width of the butterfly-shaped sheath 123 matches the width of the first groove and the second groove, bonding is not required, and the fitting of the butterfly-shaped sheath 123 with the first groove and the second groove makes the composite component 1 integrated, and it is easy to separate and use; of course, glue can also be slightly applied at the engaging or fitting or contacting positions to further integrate the composite component 1.

[0041] In Example 3 and Example 5, the number of butterfly units in a single composite component is at least two; for example, when the number of butterfly units in a single composite component is two, a Figure 4 structure can be formed by bending the connection bar; when the number of butterfly units in a single composite component is three, a Figure 3 structure can be formed by bending the connection bar; when the number of butterfly units in a single composite component is four, a Figure 6 structure can be formed by bending the connection bar; for other structures, those skilled in the art can achieve them under the above inspiration.

[0042] In this application, in Examples 1 to 3, the number of butterfly units in the final optical cable is not less than three.

[0043] A multi-unit butterfly-shaped optical cable with composite components described in this application has a single composite component, and the composite component is of an integral structure; The composite component is composed of m connecting bars and n butterfly units, where m≥3, n≥2, and both m and n are integers. Each butterfly unit consists of two reinforcing members, an optical communication component, and a butterfly sheath. The two reinforcing members are respectively located on the upper and lower sides of the optical communication component. The butterfly sheath entirely wraps the reinforcing members and the optical communication component. The cross-section of the butterfly sheath is in the shape of a runway or a rectangle, and the optical communication component is located in the center of the butterfly sheath. A connecting bar is connected to the outer edge on the left and right sides of each butterfly sheath. The space above the connecting bar is the second groove, and the space below the connecting bar is the first groove. When m - n = -1, the outer edge of the outermost butterfly unit has no connecting bar; when m - n = 1, the outer edges of the outermost butterfly units all have connecting bars; when m = n, only one of the outer edges of the two outermost butterfly units has a connecting bar. The cross-section of the composite component is in a row structure or a circular structure. When the cross-section of the composite component is in a row structure, all the connecting bars are on the same straight line, all the butterfly units are arranged in parallel, and the left-right symmetry plane of each butterfly sheath is perpendicular to the connecting bar. The up-down symmetry planes of all the connecting bars are in the same plane, and each butterfly unit is symmetric about the up-down symmetry plane of the connecting bar. When the cross-section of the composite component is in a circular structure, the outermost connecting bars are bonded together, and the composite component forms a closed circular structure. All the connecting bars are on the first circumference, all the butterfly units are arranged in a circle, the left-right symmetry plane of each butterfly sheath passes through the center of the first circumference, the top ends of the inner butterfly sheaths are on the second circumference, and the inner space enclosed by the second circumference is the central cavity, which is connected to the first groove.

[0044] In this application, the butterfly units within the same composite component are the same, having the same shape and the same size.

[0045] In the above-described embodiment where the cross-section of the composite component is in a row structure, on the plane perpendicular to the axis in the extending direction of the butterfly sheath, the uppermost ends of the butterfly sheaths are in the same plane, the lowermost ends of the butterfly sheaths are in the same plane. The distance between the uppermost end and the lowermost end of the butterfly sheath is the length or height of the butterfly sheath, and the distance between the leftmost and rightmost sides of the butterfly sheath is the width of the butterfly sheath. The length or height of the butterfly sheath is greater than the width of the butterfly sheath. The circular structure of the cross-section of the composite component is formed by winding or bending and folding the cross-section of the composite component in a row structure, and then bonding the free ends of the outermost connecting bars.

[0046] In the above-described embodiment, m = n + 1. To better implement it, the lengths of the middle connecting bars are equal, and the sum of the lengths of the two outermost connecting bars is equal to the length of any one of the middle connecting bars.

[0047] Certainly, in the embodiment where the cross-section of the composite component has a row-like structure, it is also possible that m + 1 = n, that is, the connecting strip on the outer side of the outermost butterfly sheath is not provided, that is, there is only a connecting strip between the butterfly sheaths, achieving the purpose of saving materials and being more beautiful.

[0048] In the multi-unit butterfly lead-in optical cable with a composite component described in this application, the material of the connecting strip is plastic.

[0049] In the multi-unit butterfly lead-in optical cable with a composite component described in this application, the material of the strengthening member is steel wire, copper wire, aluminum wire, iron wire, glass fiber reinforced plastic rod or aramid yarn.

[0050] In the multi-unit butterfly lead-in optical cable with a composite component described in this application, the optical communication component is a single optical fiber or an optical fiber ribbon or a tight-buffered optical fiber.

[0051] In the multi-unit butterfly lead-in optical cable with a composite component described in this application, the material of the butterfly sheath is plastic.

[0052] In the multi-unit butterfly lead-in optical cable with a composite component described in this application, the material of the reinforcing member is steel wire, copper wire, aluminum wire, iron wire, glass fiber reinforced plastic rod or aramid yarn.

[0054] In the multi-unit butterfly lead-in optical cable with a composite component described in this application, the material of the support member is plastic.

[0055] In the multi-unit butterfly lead-in optical cable with a composite component described in this application, the material of the telescopic layer is plastic.

[0056] One type of the composite component in this application is a linear structure and a staggered stacked structure of multiple linear structures; another is a circular closed structure formed by connecting the head and tail of a single linear structure; still another is a circular closed structure formed by bending and splicing multiple composite components; and there is also one type: a support component is placed in the central cavity formed by the above-mentioned another type and still another type.

[0057] This application has the advantages of rapid assembly, stable structure after assembly, and excellent mechanical properties; in the case of the circular closed structure, the height direction of the butterfly sheath of the butterfly unit is towards the center of the circle, which significantly reduces the size of the optical cable and the size of the central cavity; moreover, the structure is stable and reliable, and it will not easily come apart, so it is convenient and flexible to use.

[0058] In this application, the material of the connecting strip is plastic, which is a material that can be melted by ultrasonic waves. When the connecting strips are joined together, the end faces of the connecting strips are bonded together by ultrasonic heating, and the production speed is very fast.

[0059] In this application, when there is only one composite component, the circular structure can also be formed by integral extrusion, that is, it is not necessary to form a circumference by bonding the connecting strips; this production method is also very convenient.

[0060] This application has the following main beneficial technical effects: simple structure, easy to assemble, better mechanical properties, significant reduction in the size of the optical cable, more stable and reliable structure, and more convenient and flexible to use.

[0061] This application can be used as an intelligent sensor or an intelligent sensing element; since it can transmit voice and images, it can also be used as a physical sensor, such as a voice sensor or an image sensor; since it transmits optical signals through the total reflection principle, it can also be used as a distance sensor; the optical fiber in this application itself is an optical waveguide, so it can be used as an optical waveguide, such as an array optical waveguide or a diffraction optical waveguide; this application can also be used in the field of optical computing, as part of optical computing, optical computing, and optical network computing, such as optical chip computing.

[0062] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations on the present invention. The protection scope of the present invention should be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
