Description

Technical Field

[0001] The utility model relates to the technical field of communication cables, in particular to a reinforced self-supporting butterfly-shaped optical fiber ribbon data cable. Background Art

[0002] Fiber optic ribbon data cable is a communication cable used for high-speed data transmission. It consists of multiple optical fibers tightly arranged and packaged together to form a fiber optic ribbon, which is then combined with other components (such as reinforcement elements and sheath materials) to form a complete cable. Compared with single optical fiber cables, fiber optic ribbon data cables have higher density and better manageability. They are very suitable for use in data centers, local area networks (LANs), metropolitan area networks (MANs) and other application scenarios that require a large number of optical fiber connections.

[0003] Butterfly-shaped fiber-optic data cable, also known as butterfly cable, is named for its shape resembling butterfly wings. It is highly flexible, easy to install and beautiful, and is very suitable for use in the "last mile" fiber-to-the-home (FTTH) or fiber-to-the-building (FTTB) network deployment;

[0004] Through the above content, we have mastered the actual application of optical fiber ribbon data cables during operation, and found that there are still some shortcomings. When the existing data cables are connected and assembled, the connecting ends generally adopt a single-type connection, which meets the connection requirements of the cables. However, the protection of the connecting point of the single-type cable is relatively simple, which makes it possible for personnel to plug and unplug it at will, affecting the stability and reliability of the cable during operation. When the cable is pulled by the tension of the wire body, it is easy to cause the cable connecting end to separate;

[0005] Therefore, the present application proposes a reinforced self-supporting butterfly-shaped optical fiber ribbon data cable. Utility Model Content

[0027] Embodiment 1

[0028] In order to solve the technical problems in the background technology, a reinforced self-supporting butterfly-shaped optical fiber ribbon data cable is provided as follows:

[0029] Combination Figure 1-Figure 6 As shown, the utility model provides a reinforced self-supporting butterfly-shaped optical fiber ribbon data cable, including a sheath 1, both ends of the sheath 1 are butt-connected with a sleeve seat 4, a cable joint 5 is fixedly installed on the sleeve seat 4, and the cable joint 5 is respectively provided with a docking port 1 51 and a docking port 2 52, five groups of optical fiber data lines 8 are sheathed inside the sheath 1, and the ends of the optical fiber data lines 8 are butt-connected with the cable joint 5, reinforcing steel wires 9 are sheathed on the sheaths 1 above and below the optical fiber data lines 8, and a locking assembly 6 is butt-connected to the outer side of the sleeve seat 4, and a protective assembly 2 that cooperates with each other is assembled on the locking assembly 6;

[0030] The optical fiber data line 8 is distributed inside the sheath 1 to ensure that the optical fiber is located in the center of the optical cable, which provides good protection for the optical fiber and improves the stability and reliability of the structure. The working strength of the cable is further increased by cooperating with the reinforcing steel wire 9 to avoid or reduce the breakage of the cable during construction and operation. The mutual cooperation between the sleeve 4 and the cable joint 5 enables the cables to be docked with each other. At the same time, the closed protection of the cable docking point is achieved through the mutual cooperation between the outer locking component 6 and the protective component 2, thereby ensuring the stability and reliability of the cable docking point during operation. The protective structure can be quickly disassembled and assembled from the docking point to achieve continuous use.

[0031] The protection assembly 2 includes a protection cover 1 21, a splicing plate 22, a splicing interface 23, and a protection cover 2 24; the locking assembly 6 includes a docking plate 61, a docking sleeve 62, and a threaded bolt 63. The outer side of the sleeve 4 is docked with a docking sleeve 62, and the end face of the docking sleeve 62 is fixedly mounted with a docking plate 61. The docking plate 61 is provided with a corresponding docking hole 611, and the docking plate 61 is docked with a threaded bolt 63 through the docking hole 611. The docking plate 61 is respectively fixedly mounted with a protection cover 1 21 and a protection cover 24, and the protection cover 1 21 and the protection cover 24 are spliced ​​with each other through the splicing plate 22 and the splicing interface 23.

[0032] When the cable joint 5 forms a docking relationship, personnel can dock it through the protective cover 1 21 and the protective cover 2 24, and ensure that the splicing plate 22 and the splicing interface 23 are docked with each other to complete the close docking of the two. After the docking is completed, the docking sleeve 62 and the sleeve seat 4 are docked and clamped with each other, and personnel can achieve close docking of the two through the docking plate 61 and the threaded bolt 63, so that the docking between the protective cover 1 21 and the protective cover 2 24 can be completed, and the docking protection of the cable joint 5 can be achieved.

[0033] Embodiment 2

[0034] like Figure 1 and Figure 6 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0035] In this embodiment, grooves 13 are disposed on both sides of the sheath 1 , and reinforcing ribs 11 are disposed inside the grooves 13 . The reinforcing ribs 11 and the sheath 1 are made of the same material.

[0036] The groove 13 on the sheath 1 ensures that the optical fiber in the sheath 1 is easy to separate, convenient for connection and termination; and the reinforcement rib 11 greatly reduces the degree of cracking of the groove 13 during separation, which has a good staged suppression effect.

[0037] In this embodiment, a sub-assembly 3 is fixedly connected to the top of the sheath 1 , and a steel strand 10 is sheathed inside the sub-assembly 3 . The steel strand 10 passes through the sheath 4 and extends into the second docking port 52 .

[0038] The sub-assembly 3 is used to realize the built-in assembly of the steel strand 10 and also realize the mutual connection with the sheath 1. The steel strand 10 in the sub-assembly 3 can be used to facilitate the suspension of the cable, making it suitable for self-supporting overhead applications.

[0039] Embodiment 3

[0040] like Figure 1-Figure 6 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0041] In this embodiment, the locking assembly 6 further includes a positioning pin 64 , and the inner wall of the docking sleeve 62 is fixedly mounted with the positioning pin 64 . Both sides of the sleeve seat 4 are provided with positioning holes 41 , and the positioning holes 41 and the positioning pin 64 are docked and matched with each other.

[0042] During this period, when the docking sleeve 62 and the socket 4 are fitted and docked, the positioning pin 64 on the inner wall of the docking sleeve 62 will be inserted into the positioning hole 41, so as to achieve the fitting and docking between the docking sleeve 62 and the socket 4. Its effect can also prevent the docking sleeve 62 and the socket 4 from being misaligned, thereby ensuring the stability of the two after docking.

[0043] In this embodiment, the threaded bolt 63 is engaged with the docking hole 611 by means of threads, and a hexagonal rotation hole 631 is provided at the end of the threaded bolt 63 .

[0044] By combining the above content, personnel need to first use tools to cooperate with the hexagonal rotating hole 631, and then realize the rotation of the threaded bolt 63 through the docking cooperation between the two. At that time, the threaded bolt 63 can be connected with the docking hole 611 through threads, so as to complete the connection and fixation between the docking sleeve 62, complete the docking set of the sleeve seat 4, and after the docking is completed, the threaded bolt 63 is built into the docking hole 611.

[0045] In this embodiment, the end of the optical fiber data line 8 extends into the first docking port 51 , and a welding head 7 is welded to the end of the line.

[0046] The end of the steel strand 10 extends into the docking port 51, firstly to ensure that the operating length of the strand 10 is consistent with that of the cable, and secondly to facilitate the docking of the cables and provide space for docking, thus ensuring the stability of the cable during lifting.

[0047] In this embodiment, a hoop 12 is mounted on the sheath 1 and the subassembly 3 .

[0048] The hoop 12 can cooperate with the lifting of the cable to ensure the compactness of the connection between the sheath 1 and the sub-assembly 3 when the sub-assembly 3 is lifted, while reducing the possibility of wire explosion and breakage between the sheath 1 and the sub-assembly 3.
