Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, are intended to be within the scope of the present application.

The terms "first" and "second" and the like in this application are used for distinguishing between different objects and not for describing a particular sequential order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps, operations, components, or modules is not limited to the particular steps, operations, components, or modules listed but may optionally include additional steps, operations, components, or modules inherent to such process, method, article, or apparatus.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

As shown in fig. 1 to 5, the optical fiber cartridge with a wire harness clamping function of the exemplary embodiment includes a cartridge body 1, a winding mechanism 2, and a cover body 3. The winding mechanism 2 comprises two semicircular grooves 21, an outer sleeve 22, two inner sleeves 23, two screws 24 and a driving assembly 25. The outer sleeve 22 is fixed to the bottom wall of the case 1, and two inner sleeves 23 are slidably fitted inside the outer sleeve 22. Two screws 24 are rotatably mounted inside the outer sleeve 22 and are screwed with the inner walls of the two inner sleeves 23, respectively. The drive assembly 25 connects the two screws 24 and is responsible for driving the screws 24 in rotation. One end of the two inner sleeves 23, which are far away from each other, is fixedly connected with the two semicircular groove bodies 21 respectively, and the two semicircular groove bodies 21 are connected with the bottom wall of the box body 1 in a sliding manner respectively. The cover 3 contacts the upper end of the semicircular groove body 21 in a closed state.

More specifically, the optical fiber harness is wound between the two semicircular grooves 21, and thus the optical fiber harness is placed in the groove of the semicircular groove 21, thereby achieving the arrangement of the harness. When the cover 3 is in the closed state, it closes the top of the semicircular groove body 21, thereby realizing clamping fixation of the optical fiber bundle, so that the optical fiber bundle is clamped between the cover 3 and the groove bottom of the semicircular groove body 21.

In practical application, after the wire harness is wound, the driving assembly 25 drives the two screws 24 to rotate in different directions at the same time. The two screws 24 drive the two inner sleeves 23 to extend, and the inner sleeves 23 move the two semicircular grooves 21 away from each other. In this way, the bundle of optical fibers wound between the two semicircular grooves 21 is tensioned, thereby effectively preventing the bundle from falling out during movement or transportation of the fiber optic enclosure. By adjusting the distance between the two semicircular grooves 21, the winding circumference of the wire harness can be adjusted. In more detail, as the distance between the two semicircular grooves 21 increases, the circumference of the optical fiber bundle during the winding process increases accordingly, which enhances the practicality of the optical fiber cassette. The optical fiber box with the optimal design not only improves the efficiency of wire harness management, but also improves the stability of the wire harness in the moving or transferring process of the optical fiber box.

As an example, the case 1 and the cover 3 are connected to each other by a hinge 11. In particular, the hinge 11 serves as a connecting element for hinging the case 1 and the cover 3. This design enhances the structural stability of the fiber optic cassette and further enhances its convenience and flexibility during use.

The hinged connection may enhance the structural stability of the fiber optic enclosure because it provides a secure and reliable connection. The hinge 11 ensures that the case 1 and the cover 3 are kept in place, preventing unnecessary movement or sliding when opening or closing the cover 3. In this way, the cover 3 can be ensured to be correctly and firmly fixed on the box 1 when being closed, and the safety of the internal optical fiber wire harness is prevented from being influenced by accidental opening of the cover.

Of course, "structural stability" is also understood herein as operational stability or service stability, meaning that the predictability and controllability of the behavior of the fiber optic cassette is ensured during operation (e.g., opening and closing of the cover 3). Meanwhile, the hinge connection reduces abrasion between the box body and the cover body caused by frequent opening and closing, so that the durability of the optical fiber box is improved.

As an embodiment, the inside of the box body 1 is provided with a mounting groove 12, and the inside of the mounting groove 12 is provided with a first clamping block 13 and a spring piece 14. The first clamping block 13 is movably arranged in the mounting groove 12, and the elastic sheet 14 contacts the inner wall of the mounting groove 12 to provide elastic support for the first clamping block 13. The first clamping block 13 is provided with a clamping groove 131, the lower surface of the cover body 3 is provided with a second clamping block 31, and the second clamping block 31 is provided with a claw 311 matched with the clamping groove 131. The side of the first clamping block 13 opposite to the elastic sheet 14 is provided with a push rod 15, and the push rod 15 passes through the side wall of the box body 1.

More specifically, the claw 311 of the second clamping block 31 is buckled in the clamping groove 131 of the first clamping block 13, so that the cover 3 is fixed. When the cover body 3 needs to be opened, the ejector rod 15 is pressed, the ejector rod 15 extrudes the first clamping block 13, the elastic piece 14 is compressed, at the moment, the first clamping block 13 is separated from the second clamping block 31, and the cover body 3 can be opened. After the push rod 15 is not pressed, the elastic piece 14 drives the first clamping block 13 to return to the initial position under the action of the restoring force of the elastic piece 14. When the cover body 3 is closed, only the clamping claw 311 of the second clamping block 31 is buckled in the clamping groove 131 of the first clamping block 13, and the cover body 3 is fixed again.

The design effectively realizes the quick opening and closing of the cover body, ensures the stability of the cover body when the cover body is closed, simultaneously provides the protection for the fiber harness, and prevents the potential damage to the fiber harness caused by the accidental opening of the cover body.

As an embodiment, the number of the mounting groove 12, the first clamping block 13, the elastic piece 14, the second clamping block 31 and the ejector rod 15 is two, and the pressing plate 16 is connected between the two ejector rods 15.

In this design, when the cover 3 is in the locked state, the claws 311 of the two second clamping blocks 31 are respectively locked in the locking grooves 131 of the two first clamping blocks 13, so as to ensure firm locking of the cover 3. The two-point fixing design effectively enhances the stability of the structure.

When the cover body 3 needs to be opened, the pressing plate 16 is pressed, the pressing plate 16 drives the two ejector rods 15 to move, the two ejector rods 15 respectively squeeze the two first clamping blocks 13, the two elastic sheets 14 are compressed, at the moment, the two first clamping blocks 13 are separated from the corresponding second clamping blocks 31, and the cover body 3 can be opened.

When the cover body 3 is closed, the clamping claws 311 of the two second clamping blocks 31 are respectively buckled in the clamping grooves 131 of the two first clamping blocks 13 again through direct buckling, so that the cover body 3 is fixed.

The design of the double fixing points not only improves the buckling stability of the cover body 3, but also facilitates the opening and closing of the cover body 3, so that the operation can be fast and conveniently carried out when the inspection and maintenance of the internal structure of the box body 1 are required. This design further improves the utility, reliability and durability of the fiber optic cassette.

As one example, the drive assembly 25 is comprised of a drive bevel gear 251, a drive shaft 252, a rocker 253, and two driven bevel gears 254. The drive shaft 252 passes through the upper wall of the outer sleeve 22 and is in rotational connection therewith. Two driven bevel gears 254 are fixedly attached to the screw 24, respectively. The rocker arm 253 is engaged with two driven bevel gears 254 and fixedly connected to the upper end of the drive shaft 252. The lower end of the driving shaft 252 is connected to the driving bevel gear 251, and the driving bevel gear 251 is connected to two driven bevel gears 254 in mesh.

In a specific operation, the rocker 253 is rotated to drive the drive bevel gear 251 to rotate by rotating the rocker 253. The rotation of the drive bevel gear 251 drives the two driven bevel gears 254 to rotate synchronously but in opposite directions, which in turn drives the two screws 24 to rotate synchronously but in opposite directions. The rotation of the two screws 24 guides the inner sleeve 23 to move towards or away from each other, thereby effecting control of the screws 24.

The design effectively realizes synchronous but reverse rotation of the double screws, further enhances the functionality of the fiber optic box, and improves the stability and reliability of the fiber optic box in the use process. Meanwhile, the relative position of the inner sleeve 23 is adjusted, so that the fixed perimeter of the optical fiber wire harness is adjusted, and the practicability and the flexibility of the optical fiber box are improved.

As an example, the bottom wall of the box 1 is provided with two guide shafts 4, and two semicircular grooves 21 are designed to be slidably mounted between the two guide shafts 4. The arrangement of the two guide shafts 4 aims at guiding the semicircular groove body 21, and ensures that the semicircular groove body 21 can slide between the two guide shafts 4.

In another embodiment, the cross-section of the outer sleeve 22 and of both inner sleeves 23 is rectangular. Specifically, the rectangular cross section design of the outer sleeve 22 and the two inner sleeves 23 endows the outer sleeve 22 with the functions of guiding and limiting the inner sleeve 23, so that the inner sleeve 23 can stretch and retract under the guiding of the outer sleeve 22, and the inner sleeve 23 is prevented from rotating relative to the outer sleeve 22 in the stretching process.

As an embodiment, two bearings 26 with seats are provided inside the outer sleeve 22, and the two screws 24 are respectively connected with the two bearings 26 with seats in a rotating manner. Specifically, the provision of the seated bearing 26 facilitates the driving of the screw 24.

As an example, a wire holder 5 is provided on one side of the case 1. Specifically, the wire holder 5 is mainly used for mounting and fixing the optical fiber harness so that the optical fiber harness can be stably accessed into the optical fiber box.

The exemplary embodiments of the present application may be combined with each other, and exemplary embodiments obtained by combining also fall within the scope of the present application.

The present application has been described with particular application to the principles and embodiments thereof, the description of the above examples being only for aiding in the understanding of the method of the present application and its core ideas; meanwhile, those skilled in the art will have variations in the specific embodiments and application scope in light of the ideas of the present application, and the present description should not be construed as limiting the present application in view of the above.
