Description

Technical Field

[0001] This invention relates to the field of optical fiber communication technology, and more particularly to a signal transmission butterfly cable. Background Technology

[0002] With the continuous development of fiber optic communication, indoor structured cabling, fiber-to-the-home (FTTH), and low-voltage signal transmission, butterfly-shaped optical cables have been widely used in indoor fiber optic cabling, wall cabling, entry-point cabling, and terminal panel connections due to their flat structure, small size, and ease of stripping and installation. A typical butterfly-shaped optical cable is a single, independent flat structure, generally consisting of a fiber core and a butterfly-shaped outer sheath covering the core. The outer sheath usually has tear grooves on both sides for easy stripping, allowing installers to quickly peel off the sheath and expose the fiber core during splicing or termination.

[0003] In applications requiring multi-channel, multi-core, or multi-route signal transmission, existing technologies typically employ multiple butterfly cables combined or multi-core integrated butterfly cable structures. However, existing integrated butterfly cables generally only allow for the independent disassembly of individual butterfly cables. After disassembly, each butterfly cable unit tends to form separate individual cable bodies, making it difficult to maintain a neat, sheet-like shape. This results in poor adaptability in scenarios requiring neat, low-protrusion, and easily concealed installation, such as wall-mounted, panel-mounted, and baseboard-concealed installations. Especially during batch cabling, the dispersed arrangement of individual cables not only affects construction efficiency but also hinders later identification, organization, and maintenance, and easily leads to a cluttered appearance, affecting the aesthetics of indoor wiring.

[0004] Therefore, there is an urgent need for a signal transmission butterfly cable that can be laid flat as a whole, can be torn into pieces as needed, maintains a regular sheet shape after being split, and can utilize the space between the butterfly cable units to achieve self-holding and clamping functions. Summary of the Invention

[0005] In view of at least one of the above technical problems, the present invention provides a signal transmission butterfly cable that adopts structural improvements to maintain a regular sheet-like shape.

[0006] According to a first aspect of the present invention, a signal transmission butterfly cable is provided, comprising: Multiple butterfly cable units, each butterfly cable unit containing a fiber core, are fixedly connected to form a sheet-like structure, and the sheet-like structure is arranged in a stacked manner. Adjacent sheet-like structures are fixedly connected by multiple connectors; A tear strip is formed between the connector and the butterfly cable unit, and multiple receiving spaces for accommodating optical cables are formed between the two sheet-like structures and the connector. Before and after the tear strip tears, the connector clamps the optical cable contained in the receiving space.

[0007] In some embodiments of the present invention, the butterfly cable unit includes two symmetrically arranged sheaths, and the fiber core is located between the two sheaths; Several pairs of tear openings are symmetrically arranged on both sides of the extending direction of the sheet structure. The tear openings are arranged along the length direction of the sheath and are arranged corresponding to the location of the fiber core and the connection point of two adjacent butterfly cable units.

[0008] In some embodiments of the present invention, the tear is a V-shaped groove.

[0009] In some embodiments of the present invention, the two ends of the connector are connection ends connected to the sheath, and the two connection ends gradually converge toward the center to form a contraction section.

[0010] In some embodiments of the present invention, the concave area surface of the shrinkage section sidewall and the V-shaped groove surface of the tear jointly compress and fix the optical cable contained in the receiving space.

[0011] In some embodiments of the present invention, each side of the cross-sectional polygon of the accommodating space is tangent to the same inscribed circle.

[0012] In some embodiments of the present invention, the tear strip is provided along the length direction of the sheath, and the tear strip includes a connecting strip disposed at the center of the connecting end, and gaps disposed on both sides of the connecting strip.

[0013] In some embodiments of the present invention, the gap is located on the sidewall of the connecting end and is arranged parallel to the sidewall of the sheath.

[0014] In some embodiments of the present invention, when one side of the connecting strip is disconnected, the optical cable squeezes the connector to tilt, the connecting end abuts against the sheath surface, and the connector remains in a clamped state.

[0015] In some embodiments of the present invention, the sheath is in the shape of a regular octagon, two adjacent sheaths are connected by one side, the V-shaped groove is formed by the other side of two adjacent sheaths, and the connector is connected to the side of the sheath adjacent to the V-shaped groove.

[0016] The beneficial effects of this invention are as follows: This invention forms a sheet-like structure by fixing multiple butterfly cable units together, and the multiple sheet-like structures are arranged in a stacked manner. Adjacent layers of sheet-like structures are connected by connectors, and a receiving space for accommodating optical cables is formed between the connectors and the butterfly cable units. This results in a neat sheet-like layout of the signal transmission butterfly cable as a whole. Compared with the existing method of multiple independent butterfly cables being laid out in a dispersed manner, this method can reduce the messiness of the wiring and facilitate wall-mounting, panel mounting, and concealed installation on skirting boards. By setting a tear strip between the connectors and the butterfly cable units, the sheet-like structure can be torn into pieces as needed. Before and after tearing, the connectors clamp the optical cables, preventing the optical cables from falling out of the receiving space after being split. This solves the problem that existing integrated butterfly cables are difficult to maintain a neat wiring state after being split, and improves the construction organization and the convenience of later maintenance.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] like Figures 1 to 8 The signal transmission cable shown includes: Multiple butterfly cable units 1, such as Figures 1 to 4 As shown, the butterfly cable unit 1 contains a fiber core 11, and multiple butterfly cable units 1 are fixedly connected to form a sheet structure, which is arranged in layers. like Figure 3 As shown, adjacent sheet-like structures are fixedly connected by multiple connectors 2; like Figure 3 As shown, a tear strip 3 is formed between the connector 2 and the butterfly cable unit 1, and multiple accommodating spaces 4 for accommodating optical cables 5 are formed between the two sheet-like structures and the connector 2. Before and after the tear strip 3 tears, the connector 2 clamps the optical cable 5 contained in the containment space 4.

[0024] In this invention, multiple butterfly cable units 1 are fixedly connected to form a sheet-like structure, and these sheet-like structures are stacked. Adjacent layers of sheet-like structures are connected by connectors 2. The connectors 2 and the butterfly cable units 1 form a receiving space 4 for accommodating the optical cable 5. This results in a neat, sheet-like layout of the signal transmission butterfly cable. Compared to the existing method of multiple independent butterfly cables being laid out in a dispersed manner, this reduces the clutter of the wiring and facilitates wall-mounting, panel mounting, and concealed installation on baseboards. By setting a tear strip 3 between the connectors 2 and the butterfly cable units 1, the sheet-like structure can be torn into pieces as needed. Before and after tearing, the connectors 2 clamp the optical cable 5, preventing it from detaching from the receiving space 4 after disassembly. This solves the problem of maintaining a neat wiring state after disassembly in existing integrated butterfly cables, improving construction organization and subsequent maintenance convenience. It should be noted that the number of layers of the sheet-like structure, the number of connectors 2, and the number of receiving spaces 4 can be set according to actual wiring requirements.

[0025] Specifically, such as Figure 3 , Figure 4 As shown, the butterfly cable unit 1 includes two symmetrically arranged sheaths 12, with the fiber core 11 located between the two sheaths 12. Several pairs of tear openings 13 are symmetrically arranged on both sides of the sheet-like structure's extension direction. The tear openings 13 are arranged along the length of the sheaths 12, corresponding to the location of the fiber core 11 and the connection points of adjacent butterfly cable units 1. The two sheaths 12 are used to cover and protect the fiber core 11, and connect with the sheaths 12 in adjacent butterfly cable units 1 to form a sheet-like structure. The tear openings 13, corresponding to the location of the fiber core 11 and the connection points of adjacent butterfly cable units 1, are arranged along the extension direction of the fiber core 11 to form a preset tear path under external force. This ensures that the butterfly cable unit 1, while maintaining its overall structure, can be stripped or separated along the corresponding location of the fiber core 11 or the unit connection point. This solves the problem of existing butterfly cables being inconvenient to disassemble and organize, facilitating subsequent wiring and construction operations. As an alternative implementation, the tear 13 may be integrally formed during the molding of the sheath 12, or it may be formed by cutting, pressing or molding after the sheath 12 is molded. This example does not constitute a limitation on the scope of protection.

[0026] refer to Figure 4 As shown, the tear opening 13 is a V-shaped groove. The opening of the V-shaped groove faces the outside of the sheath 12, and its bottom extends towards the location of the fiber core 11. The V-shaped structure reduces the local thickness of the sheath 12, allowing the sheath 12 to tear directionally along the V-shaped groove when subjected to external force. The V-shaped grooves on both sides of the sheath 12 are arranged in a corresponding relationship to ensure that both sides of the butterfly cable unit 1 have a consistent tearing path. By setting the tear opening 13 as a V-shaped groove extending along the length of the sheath 12 and arranged opposite to each other on both sides, it is easier to peel the sheath 12 in a preset direction, improving the regularity of the butterfly cable unit 1 disassembly process.

[0027] like Figure 8 As shown, the connector 2 has two connecting ends 21 that connect to the sheath 12. The two connecting ends 21 gradually narrow towards the center to form a contraction section 22. The connecting ends 21 are used to connect and fix the connector 2 to the sheath 12. The contraction section 22 is formed by gradually narrowing from the connecting ends 21 towards the center, so that the connector 2 as a whole forms a contour structure that narrows in the middle. The two connecting ends 21 are symmetrically arranged about the center position of the connector 2, and the contraction section 22 extends continuously along the length of the connector 2, so that the connector 2 forms a stable connection structure between adjacent sheet-like structures. As an optional implementation, the connecting ends 21 and the sheath 12 can be integrally molded, or fixed by heat fusion or adhesive bonding. This example does not constitute a limitation on the scope of protection.

[0028] like Figure 5 , Figure 6 , Figure 8 As shown, the recessed area of ​​the sidewall of the contraction section 22 and the V-shaped groove of the tear 13 together compress and fix the optical cable 5 housed in the receiving space 4. The optical cable 5 is arranged in the area enclosed by the opposing contraction section 22 and the V-shaped groove. The contraction section 22 and the V-shaped groove are located at different positions on the outer periphery of the optical cable 5. The outer surface of the optical cable 5 abuts against a portion of the contraction section 22 and the V-shaped groove. The contraction section 22 and the V-shaped groove 13 apply contact pressure to the optical cable 5, thereby achieving a fixed arrangement of the optical cable in the receiving space 4. Even during the tearing or movement of the sheet structure, the contraction section 22 and the V-shaped groove 13 can still maintain contact and engagement with the optical cable 5, ensuring the stable arrangement of the optical cable 5 in the receiving space. As an optional embodiment, the recess depth of the contraction section 22 and the width of the V-shaped groove can be adjusted according to the diameter of the optical cable 5. This example does not constitute a limitation on the scope of protection of the claims.

[0029] like Figure 5 , Figure 7 As shown, each side of the polygonal cross-section of the accommodating space 4 is tangent to the same inscribed circle. The center of the inscribed circle coincides with the geometric center of the accommodating space 4, and the sides are arranged along the tangent direction of the inscribed circle, forming an equidistant and continuous polygonal outline. The accommodating space 4 can maintain a uniform and stable cross-section during the arrangement of the optical cable 5, and the optical cable 5 is evenly stressed within the space, avoiding local compression or displacement, and facilitating the neat arrangement of the optical cable 5 within the sheet-like structure. Of course, this is adapted for a single optical cable 5. As an optional embodiment, the number of polygonal sides and the radius of the inscribed circle can be adjusted according to the diameter of the optical cable 5 and the wiring requirements. This example does not constitute a limitation on the scope of protection of the claims.

[0030] like Figure 6As shown, the tear strip 3 is arranged along the extension direction of the butterfly cable unit 1. The tear strip 3 includes a connecting strip 31 disposed at the center of the connecting end 21, and gaps 32 disposed on both sides of the connecting strip 31. The connecting strip 31 is used to connect the connector 2 and the butterfly cable unit 1. The gaps 32 on both sides of the connecting strip 31 form a separating area, so that the tear strip 3 forms a relatively weak connecting area. The gaps 32 are continuously arranged along the extension direction of the connecting strip 31, so that the tear strip 3 can form a preset tear path along the extension direction of the butterfly cable unit 1 under the action of external force.

[0031] By setting the tear strip 3 to include a central connecting strip 31 and gaps 32 on both sides of the connecting strip 31, the problem of the existing butterfly cable connection area being difficult to directionally split is solved, so that the butterfly cable units 1 can maintain the connection state while having a preset tear area.

[0032] like Figure 6 As shown, gap 32 is located on the side wall of connecting end 21 and is parallel to the side wall of sheath 12. Connecting end 21 and sheath 12 are connected by connecting strip 31. Gap 32 extends along the length of sheath 12. The side walls on both sides of gap 32 are formed by connecting end 21 and sheath 12 respectively, and the two side walls are kept parallel and spaced apart, so that regular and continuous interval areas are formed on both sides of connecting strip 31. Through the arrangement of gap 32, a preset tear area can be formed while ensuring the connection strength between connector 2 and butterfly cable unit 1, so that tear strip 3 has a controllable splitting path along the extension direction of butterfly cable unit 1.

[0033] like Figure 5 , Figure 7 As shown, when one side of the connecting strip 31 breaks, the optical cable 5 tends to squeeze the connecting piece 2 on one side, causing it to tilt. The connecting end 21 abuts against the surface of the sheath 12 to suppress the tilt, thereby keeping the connecting piece 2 in a clamped state. Even if one side of the central connecting strip 31 breaks, the connecting piece 2 still maintains contact with the optical cable 5 and the sheath 12, thus achieving a stable fit between the connecting piece 2 and the optical cable 5 after a partial tear in the sheet structure.

[0034] like Figure 3 , Figure 5As shown, the sheath 12 is a regular octagon. Adjacent sheaths 12 are connected by one side, and a V-shaped groove is formed by the other side of adjacent sheaths 12. The connector 2 is connected to the side of the sheath 12 adjacent to the V-shaped groove. The sheath 12 is a regular octagon, and adjacent sheaths 12 are connected to each other by one side of their respective regular octagonal outlines, so that multiple sheaths 12 are sequentially and fixedly arranged along the extension direction of the sheet-like structure. After adjacent sheaths 12 are connected to each other, the other side of the two sheaths 12 that is not used for connection together forms a V-shaped groove. The V-shaped groove is located on one side of the connection area of ​​the two adjacent sheaths 12 and extends along the length of the sheath 12. The connector 2 is connected to the side of the sheath 12 adjacent to the V-shaped groove, so that a clear edge correspondence is formed between the connector 2, the sheath 12, and the V-shaped groove.

[0035] By setting the sheath 12 to a regular octagonal shape, and connecting two adjacent sheaths 12 through one side and forming a V-shaped groove from the other side, with the connector 2 connected to the side adjacent to the V-shaped groove, each side of the sheath 12 undertakes the structural functions of connection, tear guidance, and connector installation position, which makes the positional relationship between the connection area, tear area, and connector installation area of ​​adjacent butterfly cable units clear, and improves the positional stability between the structures in the sheet structure.

[0036] Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to this invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed.
