Description

Technical Field

[0001] The utility model relates to the technical field of fiber optic jumpers, and specifically relates to a double 8-shaped fiber optic jumper. Background Art

[0002] The double 8-shaped fiber optic jumper is a fiber optic jumper with a special design. It consists of two mutually parallel double-core jumpers, and these two double-core jumpers are symmetrically arranged by an adhesion method. This design enables the double 8-shaped fiber optic jumper to directly branch out a 4-core connector, solving the problems of large workload in centralized wiring of jumpers, difficult cable management, numerous and complex ends that are difficult to distinguish, thereby reducing labor costs and the probability of errors occurring during manual wiring. In addition, this fiber optic jumper is also provided with a dust cap with an anti-loss structure, which can enable users to quickly and conveniently find the dust cap of the jumper, so that the end face of the jumper connector can be protected in real time.

[0003] Patent CN210109396U proposes a double 8-shaped fiber optic jumper. On the basis of a double-core jumper, another double-core is paralleled, thus forming a double "8" - shaped jumper, which can directly branch out a 4-core connector and is provided with number identification, solving the problems of large workload in centralized wiring of jumpers, difficult cable management, numerous and complex ends that are difficult to distinguish, and further reducing labor costs and the probability of errors occurring during manual wiring; in addition, a dust cap with an anti-loss structure is provided, which can enable users to quickly and conveniently find the dust cap of the jumper, so that the end face of the jumper connector can be protected in real time.

[0004] In the above solution, because there are four plug-in ends and four branch wires, although the double cores at the rear are arranged side by side, the front end is in a loose state. When carrying or when a plug-in end is not in use, the front end is also prone to entanglement problems, and it is impossible to provide good limit for the front end. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a double 8-shaped fiber optic jumper to solve the problems raised in the above background art. The structure of the utility model is novel. Through the limiting component, the four branch wires are separated by a certain space and do not contact each other, which is convenient for carrying and storing, and at the same time, it is also convenient to take out the corresponding branch wire and plug for use, avoiding the problem of entanglement between the branch wires.

[0006] To achieve the above object, the utility model is realized by the following technical solutions: A double 8-shaped fiber optic jumper, including a cable, the cable is composed of two connecting wires adhered side by side, and a connection seat is arranged at the front end of the cable. Four branch wires are branched out on the outer side of the connection seat, and the other ends of the branch wires are connected with plugs. The four branch wires and the four plugs are arranged side by side. A dust-proof sleeve is sleeved on the outer end of the plug. A limiting component is arranged between the four branch wires. The limiting component includes a circular plate. The circular plate is located at the gap between the four branch wires. Fixing rings are fixed at the positions of the four branch wires corresponding to the circular plate, and inserting plates are arranged on the side surfaces of the fixing rings. The inserting plates can be slidably inserted into the interior of the circular plate. A first spring is fixed on the back surface of the circular plate, and the other end of the first spring is fixedly connected with the connection seat.

[0007] Furthermore, the limiting component further includes an inserting frame. The inserting frame is fixed on the side surface of the fixing ring. A vertical plate is fixed on the outer side of the inserting plate, and the protrusion on the middle surface of the vertical plate is slidably inserted into the interior of the inserting frame.

[0008] Furthermore, a second spring is fixed on the top of the inserting frame, and the other end of the second spring is fixedly connected with the vertical plate.

[0009] Furthermore, a winding ring is rotatably installed at the front end of the fixing ring through a bearing and a torsion spring.

[0010] Furthermore, a lost-proof rope is wound inside the winding ring, and the other end of the lost-proof rope is fixedly connected with the outer side of the dust-proof sleeve.

[0011] Furthermore, two supporting rings are arranged at the positions corresponding to each branch wire between the circular plate and the connection seat, and the supporting rings are semi-circular. The inner wall of the supporting ring contacts the inner side surface of the branch wire.

[0012] Furthermore, the supporting ring at the front end of the connection seat is fixedly connected with the connection seat, and the supporting ring at the rear end of the circular plate is fixedly connected with the circular plate.

[0013] Furthermore, a connecting rope is fixed between the two supporting rings, and the connecting rope contacts the surface of the branch wire.

[0014] The beneficial effects of the utility model:

[0015] 1. When the circular plate of the utility model moves to the position of the fixing ring under the elastic force of the first spring, the supporting ring connected to the circular plate will also be driven to the rear of the fixing ring. At this time, the connecting rope between the two supporting rings on the same straight line is unfolded into a straight line. The two supporting rings and the connecting rope limit the surface between the fixing ring of the branch wire and the connection seat to a certain extent from the side, avoiding the problem of entanglement.

[0016] 2. The utility model drives the winding ring to rotate through the torsion spring of the winding ring to wind the lost-proof rope, so that the dust-proof sleeve is stored at the rear end of the plug, avoiding the loss of the dust-proof sleeve and at the same time avoiding the lost-proof rope from affecting the wiring.

[0017] 3. In the present utility model, the plug board is inserted on the circular board to limit the fixing ring. At this time, the branched wires cannot move outwards and are restricted by the circular board with a certain interval between them, which is beneficial to the side-by-side arrangement of the front-end plugs. The branched wires at the back end will not contact and entangle with each other. When a single plug needs to be taken out, the vertical board is moved outwards, and the plug board moves out of the circular board. At this time, the fixing ring is separated from the circular board, and the branched wires and plugs can be used separately. The remaining parts are still limited by the circular board, which can solve the problem of bundling the redundant branched wires and plugs when not all the plugs are used, so as to avoid affecting the installation environment.

[0018] 4. Compared with the prior art, the present utility model separates the four branched wires by a certain space through the limiting component, so that they do not contact each other, which is convenient for carrying and storing. At the same time, it is also convenient to take out the corresponding branched wires and plugs for use, avoiding the problem of entanglement between the branched wires.

[0025] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific embodiments.

[0026] Please refer to Figures 1 to 5, the present utility model provides a technical solution: a double 8-shaped optical fiber jumper, including a cable 1, the cable 1 is composed of two connecting lines adhered and arranged side by side, and a connection seat 12 is provided at the front end of the cable 1. Four branch lines 11 branch out from the outside of the connection seat 12, and the other ends of the branch lines 11 are connected with plugs 13. The four branch lines 11 and the four plugs 13 are all arranged side by side. A dust-proof sleeve 14 is sleeved on the outer end of the plug 13. A limiting component 2 is arranged between the four branch lines 11. The limiting component 2 includes a circular plate 22. The circular plate 22 is located at the gap between the four branch lines 11. Fixing rings 23 are fixed at the positions of the four branch lines 11 corresponding to the circular plate 22, and insertion plates 210 are arranged on the side surfaces of the fixing rings 23. The insertion plates 210 can be slidably inserted into the inside of the circular plate 22. A first spring 21 is fixed on the back surface of the circular plate 22, and the other end of the first spring 21 is fixedly connected with the connection seat 12. The compositions of the cable 1, the connection seat 12, the branch lines 11 and the plugs 13 are the same as those of the existing double 8-shaped optical fiber jumper. The four branch lines 11 are limited by the limiting component 2 to maintain a certain distance and do not wind around each other. The front end of the plug 13 is protected by the dust-proof sleeve 14 to prevent dust from entering the inside of the plug 13. The branch lines 11 on the limiting component 2 can be taken out one by one or all taken out, and the unused branch lines 11 and plugs 13 are kept in a limited state, thereby avoiding the problem of wire segment winding.

[0027] In this embodiment, the limiting component 2 further includes an insertion frame 27. The insertion frame 27 is fixed on the side surface of the fixing ring 23. A vertical plate 28 is fixed on the outer side of the insertion plate 210, and the protrusion on the middle surface of the vertical plate 28 is slidably inserted into the inside of the insertion frame 27. A second spring 29 is fixed on the top of the insertion frame 27, and the other end of the second spring 29 is fixedly connected with the vertical plate 28. The insertion plate 210 is inserted into the circular plate 22 to limit the fixing ring 23. At this time, the branch line 11 cannot move outwards and is bound by the circular plate 22 with a certain interval between them, which is beneficial to the side-by-side arrangement of the front-end plugs 13, and the branch lines 11 at the back end will not contact and wind around each other. When a single plug 13 needs to be taken out, the vertical plate 28 is moved outwards, and the insertion plate 210 moves out of the circular plate 22. At this time, the fixing ring 23 is separated from the circular plate 22, and the branch line 11 and the plug 13 can be used alone, and the remaining parts are still limited by the circular plate 22, which can solve the problem of bundling the redundant branch lines 11 and plugs 13 in the case of incomplete use of the plugs 13 and avoid affecting the installation environment.

[0028] In this embodiment, a winding ring 24 is rotatably installed at the front end of the fixing ring 23 through a bearing and a torsion spring. An anti-loss cord 15 is wound inside the winding ring 24, and the other end of the anti-loss cord 15 is fixedly connected to the outer side of the dust cover 14. After the dust cover 14 is removed, the torsion spring of the winding ring 24 drives it to rotate to wind the anti-loss cord 15, so that the dust cover 14 is received at the rear end of the plug 13, avoiding the loss of the dust cover 14 and also avoiding the anti-loss cord 15 from affecting the wiring.

[0029] In this embodiment, two support rings 25 are provided at the positions corresponding to each branch wire 11 between the circular plate 22 and the connection base 12, and the support rings 25 are semi-circular. The inner wall of the support ring 25 is in contact with the inner surface of the branch wire 11. The support ring 25 at the front end of the connection base 12 is fixed to the connection base 12, and the support ring 25 at the rear end of the circular plate 22 is fixedly connected to the circular plate 22. A connecting cord 26 is fixed between the two support rings 25, and the connecting cord 26 is in contact with the surface of the branch wire 11. When the circular plate 22 moves to the position of the fixing ring 23 by the elastic force of the first spring 21, the support ring 25 connected to the circular plate 22 will also be driven to the rear of the fixing ring 23. At this time, the connecting cord 26 between the two support rings 25 on the same straight line is unfolded into a straight line, and the two support rings 25 and the connecting cord 26 limit the surface between the fixing ring 23 of the branch wire 11 and the connection base 12 to a certain extent from the side, avoiding the problem of winding.

[0030] When using the device, the plug board 210 is inserted on the circular plate 22 to limit the fixing ring 23. At this time, the branch wires 11 cannot move outwards and are restricted by the circular plate 22 with a certain interval between them, which is beneficial to the side-by-side arrangement of the front-end plugs 13, and the rear-end branch wires 11 will not contact and wind each other. When a single plug 13 needs to be taken out, the vertical plate 28 is moved outwards, and the plug board 210 moves out of the circular plate 22. At this time, the fixing ring 23 is separated from the circular plate 22, and the branch wire 11 and the plug 13 can be used separately. The remaining parts are still limited by the circular plate 22, which can solve the problem of bundling the redundant branch wires 11 and plugs 13 in the case of incomplete use of the plugs 13 to avoid affecting the installation environment. After the dust cover 14 is removed, the torsion spring of the winding ring 24 drives it to rotate to wind the anti-loss cord 15, so that the dust cover 14 is received at the rear end of the plug 13, avoiding the loss of the dust cover 14 and also avoiding the anti-loss cord 15 from affecting the wiring. When the circular plate 22 moves to the position of the fixing ring 23 by the elastic force of the first spring 21, the support ring 25 connected to the circular plate 22 will also be driven to the rear of the fixing ring 23. At this time, the connecting cord 26 between the two support rings 25 on the same straight line is unfolded into a straight line, and the two support rings 25 and the connecting cord 26 limit the surface between the fixing ring 23 of the branch wire 11 and the connection base 12 to a certain extent from the side, avoiding the problem of winding.
