Referring to fig. 1, the optical fiber jumper fiber accommodating device includes a housing 20, and an inlet and an outlet are provided on the housing 20; a rotating assembly 30 and a telescopic member 40 with adjustable length are arranged in the shell 20; a handle (which may be hidden, not shown in fig. 1) is fixedly connected to the rotating assembly 30 through the housing 20; a limit rail is arranged on the rotating assembly 30; the telescopic piece 40 is fixedly connected with the rotating assembly 30, and a limiting structure 50 is arranged at the end part of the telescopic piece 40;

wherein, the optical fiber jumping fiber 10 is wound on the two ends of the limit track and extends out from different inlets and outlets of the shell 20 through the limit structure 50 respectively; the expansion piece 40 is used for adjusting the bending radius of the optical fiber jumping fiber 10 to a target radius value;

the rotating assembly 30 is driven by the handle to rotate, so as to drive the two ends of the optical fiber jumper 10 to move in or out from the inlet and outlet respectively.

Specifically, as shown in fig. 1, two ends of the optical fiber patch cord 10 are respectively a patch cord first connector 101a and a patch cord second connector 101b, a first inlet and outlet 201a and a second inlet and outlet 201b are correspondingly arranged on the housing 20, the patch cord first connector 101a extends from the first inlet and outlet 201a, and the patch cord first connector 101b extends from the first inlet and outlet 201 b.

Considering that the optical fiber jumper 10 has a certain length, for example, 1.5m-3m, in actual use, the optical fiber jumper 10 with the whole length is not needed to realize the connection function, so that the optical fiber jumper 10 with the extra length needs to be stored, and the optical fiber jumper 10 with the extra length is prevented from being wound and knotted, which is inconvenient for subsequent use on one hand, and may affect the performance of the optical fiber jumper 10 on the other hand, for example, when the bending radius of the optical fiber jumper 10 is too small, the optical fiber jumper 10 may leak light.

When the optical fiber jumper fiber 10 is stored, considering that the length of the optical fiber jumper fiber 10 which is generally stored in the optical fiber jumper fiber storage device and is available for use in the prior art is fixed, the length requirement of the flexible optical fiber jumper fiber 10 under different use situations cannot be met, and the influence of the bending radius when the optical fiber is stored on the optical fiber performance is not considered in the existing storage scheme, and the optical fiber jumper fiber 10 of different types cannot be flexibly stored in the standard value range of the bending radius suitable for the performance of the optical fiber jumper fiber 10.

Therefore, in order to realize the storage of the optical fiber with variable usable length and adjustable optical fiber bending radius of the optical fiber jumper 10, in one embodiment of the present utility model, the optical fiber jumper 10 is wound on the limit rail of the rotating assembly 30, and the rotating assembly 30 is fixedly connected with the handle, so that the user can rotate the rotating assembly 30 by rotating the handle, and the optical fiber jumper 10 is rolled out of or into the limit rail along with the rotation of the rotating assembly 30, thereby realizing that the two ends of the optical fiber jumper 10 are moved out or in from the corresponding inlet and outlet of the housing 20, and the length of the optical fiber jumper 10 exposed outside the housing 20 is the length part for real-time use, and the flexible adjustment of the length part for use can be realized by controlling the rotation of the handle. Further, on the basis of flexibly adjusting the length of the fiber optic jumper 10 in real time, when taking into account the influence of unsuitable bending radius on the performance of the fiber optic jumper 10 when taking into account the temporary unused excess length of the fiber optic jumper 10, the requirements of different types and/or use scenes for the bending radius of the fiber optic jumper 10 may be different, so that in order to achieve flexible adjustment of the bending radius during taking of the fiber radius, the length-adjustable telescopic member 40 is fixedly connected with the rotating assembly 30, and a limiting structure 50 is arranged at the end part of the telescopic member 40, thereby, on one hand, the fiber optic jumper 10 is wound around the limiting track and then respectively extends from different inlets and outlets of the shell 20 through the limiting structure 50, and on the other hand, the taking of the temporary unused excess length of the fiber optic jumper 10 is achieved, and on the other hand, the bending radius of the fiber optic jumper 10 is adjusted to the target radius value through the length expansion and contraction of the telescopic member 40, thereby protecting the performance of the fiber optic jumper 10.

Specifically, the inside of the housing 20 is a hollow structure, and the internal cavity of the housing 20 can accommodate the rotating assembly 30, the telescopic rod and the limiting structure 50, and the housing 20 is used for protecting the assembly arranged therein and the housed optical fiber patch cord 10. Further, in order to facilitate the installation of the optical fiber jumper 10 into the limit rail and the limit structure 50, the housing 20 may be configured to be a snap-fit structure, specifically, the housing 20 includes an upper housing and a lower housing; the upper housing is openable or closable relative to the lower housing. It will be appreciated that the upper and lower housings are provided with respective ports on one side thereof, which when the upper and lower housings are closed form the ports of the housing 20.

The rotating assembly 30 may be fixedly disposed on the upper housing or the lower housing, so that when the upper housing is opened relative to the lower housing, the optical fiber jumping fiber 10 may be wound on the rotating assembly 30, and then after the optical fiber jumping fiber 10 is limited by the limiting track and the limiting structure 50, the upper housing and the lower housing are closed, so as to realize protection of the optical fiber jumping fiber 10 and the internal components of the housing 20, thereby the protection capability of the housing 20 in the embodiment of the utility model may reach the IP40 level or above.

Further, considering that the lengths of the optical fiber jumpers 10 are different, the required accommodating length affects the number of actually required limiting turns, and the radius range of the limiting track of the rotating assembly 30 and the adjusting range of the length of the telescopic rod are limited, at the same time, the positions of the inlet and the outlet of the housing 20 are relatively fixed, so that the optical fiber jumpers 10 can be inconvenient to extend or move from the inlet and the outlet of the housing 20, and therefore, in still another embodiment of the present utility model, a plurality of fixing pieces are fixedly arranged at different positions of the upper housing and/or the lower housing of the housing 20 respectively; the fixing member is used for fixing the rotating assembly 30.

The distance between the rotating assembly 30 and the inlet and outlet of the shell 20 is adjusted by fixing the rotating assembly 30 on the fixing pieces at different positions, so that the optical fiber jumping fiber 10 can be more conveniently stretched out or moved in from the inlet and outlet of the shell 20, and the optical fiber jumping fiber 10 can be conveniently used.

Specifically, the rotating assembly 30 includes a rotating shaft and a bearing member, wherein the rotating shaft is fixedly connected with the handle, the bearing member is movably connected with the rotating shaft, the bearing member rotates relative to the housing 20 through the rotating shaft, a limiting track is arranged on the bearing member, and the bearing member is fixedly connected with the telescopic rod. Wherein, for convenience in setting up the limit rail, the bearing member may be disc-shaped, that is, the rotating assembly 30 may be a turntable.

The limiting structure 50 may be a through hole structure, and the limiting of the optical fiber jumping fiber 10 is achieved by penetrating the optical fiber jumping fiber 10 into the through hole structure, so that the optical fiber jumping fiber 10 is ensured not to fall off in the rotating process of the rotating assembly 30, and the optical fiber jumping fiber 10 is not damaged due to limiting. Optionally, in order to improve the efficiency of accommodating the optical fiber jumping fiber 10, the through hole structure is specifically an openable through hole structure, and when the openable through hole structure is closed, the optical fiber jumping fiber 10 is limited, and when the optical fiber jumping fiber 10 is opened, the limitation of the optical fiber jumping fiber 10 is released.

It will be appreciated that, unlike the passive rotation of the rotating assembly 30 by the handle, the rotating assembly 30 may be controlled in an active manner to improve the efficiency of the optical fiber moving in and out, such as in a further embodiment of the present utility model, the optical fiber jumper accommodating device further includes an electric valve fixedly connected to the rotating assembly 30; the electrically operated valve is configured to drive the rotation assembly 30 to rotate when opened.

Further, considering that there may be a difference in the standard value of the bending radius of the different types of optical fiber jumpers 10, the smaller the distance between the limit track and the receiving structure at the end of the telescopic member 40, the smaller the influence on the performance of the optical fiber jumpers 10, so in order to further improve the adaptability of the optical fiber jumpers receiving device, in still another embodiment of the present utility model, as shown in fig. 1, the limit track includes a plurality of sub-tracks with different track radii, such as the first sub-track 301a, the second sub-track 301b, and the third sub-track 301c in fig. 1; the length of the telescopic member 40 corresponds to the track radius of the sub-track where the optical fiber patch 10 is located.

As shown in fig. 1, the track radii of the first sub-track 301a, the second sub-track 301b, and the third sub-track 301c sequentially increase. By providing a plurality of sub-tracks with different radii on the rotating assembly 30, it is convenient for a user to wind the optical fiber jump fiber 10 onto a limit track with a track radius of the target radius value according to the target radius value required by normal operation of the optical fiber jump fiber 10. Correspondingly, considering that the optical fiber jumping fiber 10 needs to be wound and fixed through the split track and then limited through the limiting component, in order to keep the radius of the optical fiber to be limited and wound and fixed as consistent as possible, that is, to avoid the change of the bending radius caused by the need of crossing from the limiting track to the limiting structure 50, the length of the telescopic piece 40 corresponds to the track radius of the split track where the optical fiber jumping fiber 10 is limited, thereby reducing the crossing distance of the optical fiber jumping fiber 10 between the limiting track and the limiting structure 50. In particular, the split track may be concentric or may be a plurality of different centers and different track radii, thereby providing a wider variety of ways of limiting on the limited area rotating assembly 30.

Further, the rotating assembly 30 includes a turntable; the telescopic members 40 are telescopic rods, and the number of the telescopic rods is at least one; the middle part of at least one telescopic link with the center fixed connection of carousel, the both ends of at least one telescopic link set up in the circumference of carousel.

Wherein the center of the turntable is the center of the circle. The two ends of the telescopic rod are arranged in the circumferential direction of the turntable, so that the optical fiber jumping fiber 10 directly enters the limiting structure 50 at the two ends of the telescopic rod after winding the limiting track on the turntable. It will be appreciated that the greater the number of telescopic rods, the greater the number of corresponding limit structures 50, and thus the more stable the limit for the optical fiber hop 10. Specifically, as shown in fig. 1, the number of the telescopic members 40 may be two; the centers of the two telescopic members 40 are crossed, and fixedly arranged in the circumferential direction of the turntable in a cross structure.

Further, the two ends of the telescopic rod are telescopic inwards or outwards relative to the center of the turntable in the direction of the straight line where the diameter of the turntable is located.

The optical fiber jumper 10 is limited outwards by the center of the turntable through the limiting track and the limiting structure 50 at the end of the telescopic rod, so that the two ends of the telescopic rod are stretched inwards or outwards in the direction of the straight line where the diameter of the turntable is located, relative to the center of the turntable, and when the length of the telescopic rod is adjusted, the bending radius of the housed optical fiber jumper 10 is adjusted to be a target radius value.

Further, the housing 20 is made of transparent or semitransparent material, and a scale for marking the length of the telescopic rod is arranged on the surface of the housing 20.

In order to facilitate the user to adjust and determine the corresponding expansion degree of the expansion link according to the required target radius value, scale information for marking the length of the expansion link may be set on the surface of the housing 20, so that the user may adjust the length of the expansion link to a corresponding value according to the read scale. Correspondingly, the housing 20 may be provided as a transparent or translucent material in order to facilitate reading of the scale.

Further, in consideration of the fact that the use environment of the optical fiber jumper 10 may be complex, the operation of the telescopic rod or the rotating assembly 30 may be caused under the influence of an external force or the installation of other devices, so as to cause the optical fiber jumper to move, in still another embodiment of the present utility model, after the length of the optical fiber jumper 10 is adjusted to a desired value, the position of the telescopic rod may be locked, so as to prevent the movement of the telescopic rod and the rotating assembly 30, and in particular, the optical fiber jumper storage device further includes the brake assembly 60; the brake assembly 60 includes a fixed portion, a movable portion, and a blocking portion; the fixed part is fixedly connected with the shell 20, the movable part is movably connected with the fixed part, and the blocking part is fixedly connected with the movable part; the movable part is used for pushing out the blocking part to the direction perpendicular to the telescopic rod, so that the blocking part limits the movement of the telescopic rod.

When the movable part is stressed in the direction perpendicular to the telescopic rod, the blocking part is pushed out in the direction perpendicular to the telescopic rod, so that the blocking part is blocked on the movement plane of the telescopic rod, and the rotation restriction of the telescopic rod is realized.

Specifically, in order to facilitate control of the brake assembly 60 outside the housing 20 to turn on or off the braking function thereof, in still another embodiment of the present utility model, a through hole is provided in the housing 20, the movable portion is provided to protrude in the through hole, and the movable portion pushes out the blocking portion in a direction perpendicular to the telescopic rod when the portion of the movable portion protruding from the housing 20 is pressed, so that the blocking portion limits the movement of the telescopic rod.

After the turntable rotates in place, the movable part protrudes out of the shell 20 by pressing, so that the movable part pushes the blocking part to the direction perpendicular to the telescopic rod, and the telescopic rod is locked and positioned by the pushed blocking part, so that the telescopic rod is ensured to be unable to move.

Correspondingly, when the length of the optical fiber jumping fiber 10 is adjusted, the part of the movable part protruding out of the shell 20 is pressed again, the blocking part is retracted, the limit of the telescopic rod is unlocked, and the rotating assembly 30 can rotate, so that the optical fiber jumping fiber 10 is retracted or rotated out. It will be appreciated that since the telescopic rod is fixedly connected to the rotating assembly 30, the rotating assembly 30 cannot rotate when the telescopic rod cannot move.

Further, the blocking part comprises two blocking bars; the distance between the two blocking rods is larger than the width of the telescopic rod; the two blocking rods are used for clamping the telescopic rod back and forth when pushing out in the direction perpendicular to the telescopic rod so as to limit the telescopic rod to move.

In order to improve the reliability of limiting the telescopic rod, the telescopic rod is pushed out to the direction perpendicular to the telescopic rod through the two blocking rods, so that the telescopic rod is clamped back and forth, the telescopic rod cannot operate in the direction parallel to the rotating assembly 30, and therefore the movement limitation of the rotating assembly 30 is achieved through the movement limitation of the telescopic rod, and the movement of the optical fiber jumping fiber 10 is limited.

The utility model provides an optical fiber jump fiber containing device which comprises a shell 20, wherein an inlet and an outlet are arranged on the shell 20; a rotating assembly 30 and a telescopic member 40 with adjustable length are arranged in the shell 20; a handle passes through the shell 20 and is fixedly connected with the rotating assembly 30; a limit rail is arranged on the rotating assembly 30; the telescopic piece 40 is fixedly connected with the rotating assembly 30, and a limiting structure 50 is arranged at the end part of the telescopic piece 40; wherein, the optical fiber jumping fiber 10 is wound on the two ends of the limit track and extends out from different inlets and outlets of the shell 20 through the limit structure 50 respectively; the expansion piece 40 is used for adjusting the bending radius of the optical fiber jumping fiber 10 to a target radius value; the rotating assembly 30 is driven by the handle to rotate, so as to drive the two ends of the optical fiber jumper 10 to move in or out from the inlet and outlet respectively. Therefore, unlike the prior art that the optical fiber jumping fiber 10 cannot be stored for adjusting the length as required and the bending radius of the optical fiber jumping fiber 10 cannot be kept within the standard radius range, so that the service performance of the optical fiber jumping fiber 10 is affected.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model, and are intended to be included within the scope of the appended claims and description.
