Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber cable connection, in particular to a highly integrated optical fiber jumper. Background Art

[0002] In the process of implementing the utility model, the inventor found that the prior art has at least the following problems:

[0003] Wireless base stations currently generally adopt a distributed approach with separate BBU and RRU, which are connected by cables. There are two media that need to be transmitted between BBU and RRU: power and information. In the early days, power and information were separated, powered by power cords, and transmitted by coaxial cables or optical cables, and concentrated in a cavity on the transmission tower, and then connected to the RRU through power jumpers and optical jumpers.

[0004] With the development of wireless base station links today, the mainstream connection has used optical-electrical hybrid cables, that is, the power line and optical cable are integrated into one cable, and the two ends of this hybrid cable are separated into multiple electrical and optical branches, which are connected to a distribution box and then connected to the RRU through power jumpers and optical jumpers. In the existing technology, it is not convenient to separate various branches after the cables are integrated, so it is more troublesome during installation. The jumper structure can be further improved. Utility Model Content

[0005] The utility model aims to provide a highly integrated optical fiber jumper which is convenient for separating various branches and can be expanded and selected.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A highly integrated fiber optic patch cord comprises a cable sheath with a plurality of optical fiber cores wrapped inside the cable sheath; a docking port is fixed at one end of the cable sheath with a diverter plate installed inside the docking port; the docking port is detachably connected to an optical fiber interface away from the end of the cable sheath; the optical fiber core is guided out along the optical fiber interface after passing through the diverter plate; a compression piece is fixed inside the cable sheath, and a plurality of compression pieces are arranged along the circumferential direction of the cable sheath.

[0008] Furthermore, the diverter plate is provided with diverter holes, and a plurality of diverter holes are provided along the circumference of the diverter plate, and an optical fiber core runs through each diverter hole.

[0009] By adopting the above technical solution, it is convenient to split the integrated light core to facilitate docking with different interfaces. At the same time, the splitter plate is detachable and can be replaced with different numbers of splitter holes for use, which has high selectivity.

[0010] Furthermore, a groove is provided on the inner wall of the docking port, and the diverter plate is placed inside the groove.

[0011] By adopting the above technical solution, the splitter plate is easily fixed.

[0012] Furthermore, a slot is provided on the outside of the docking port, and a plurality of slots are provided along the circumferential direction of the docking port. One end of each slot is connected to a card slot, and a protruding block is fixed to the card slot near the end surface of the docking port.

[0013] Furthermore, a card block is carded inside the card slot, the card block is L-shaped, the card block is fixedly connected to the end face of the optical fiber interface away from the card slot end, and the number of the card block is consistent with that of the card slot.

[0014] By adopting the above technical solution, after the optical fiber interface is docked with the docking interface, the card block on the optical fiber interface is inserted into the slot inside the docking interface, and the docking interface is rotated at the same time so that the card block enters the card slot, and then the card block is fixed by the protruding block. At the same time, the diverter plate is fixed when the optical fiber interface is docked, so that the overall optical fiber jumper is easy to disassemble for subsequent maintenance.

[0015] Furthermore, the clamping member includes a fixed tube fixed and bonded to the inner wall of the cable skin, a spring is fixed inside the fixed tube, a movable tube is fixed to the other end of the spring, the movable tube slides inside the fixed tube, and a clamping arc plate is fixed to the end of the movable tube away from the fixed tube.

[0016] By adopting the above technical solution, the wire core is placed between all the pressing arc plates, and then contacts the surface of the pressing arc plates. When in contact, the pressing arc plates receive pressure and drive the moving tube to slide along the inside of the fixed tube, thereby compressing the spring. At the same time, the spring has rebound potential energy, which reacts on the pressing arc plates, thereby tightly covering and fixing the internal optical fiber core, thereby facilitating the integrated use of different numbers of optical fiber cores.

[0017] Furthermore, a partition bar is fixed inside the optical fiber interface, and a plurality of partition bars are arranged along the length direction of the optical fiber interface.

[0018] By adopting the above technical solution, a separator is fixed inside the optical fiber interface, and several separators are arranged along the length direction of the optical fiber interface, and then the optical fiber core is led out along the intervals of the separator to separate each interface to facilitate the wiring of subsequent jumpers.

[0019] In summary, the beneficial technical effects of the utility model are:

[0020] 1. The splitter plate is used to separate the integrated light cores for easy docking with different interfaces. The splitter plate can be disassembled and replaced with different numbers of splitter holes, which has high selectivity.

[0021] 2. The pressing piece is used, and the core is placed between all the pressing arc plates, and then contacts the surface of the pressing arc plates. When in contact, the pressing arc plates receive pressure and drive the moving tube to slide along the inside of the fixed tube, thereby compressing the spring. At the same time, the spring has rebound potential energy, which reacts on the pressing arc plates, thereby tightly covering and fixing the internal optical fiber core, thereby facilitating the integrated use of different numbers of optical cores;

[0022] 3. A card slot and card block structure is adopted. After the optical fiber interface is docked with the docking interface, the card block on the optical fiber interface is passed into the slot inside the docking interface, and the docking interface is rotated at the same time so that the card block enters the card slot, and then the card block is fixed by the raised block. At the same time, the splitter plate is fixed when the optical fiber interface is docked, so that the overall optical fiber jumper is easy to disassemble for subsequent maintenance.
