All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The cable management unit of the embodiment may be used in a rack such as a server rack to manage a plurality of different types of cables, where the types of the cables may be cables (e.g., signal lines for transmitting high-frequency signals) or fiber harnesses. The following description will be given by taking only the optical fiber bundle as a representative example, but it should be understood that the present invention can be applied to cables of different forms such as an electric cable and an optical cable.

Generally, the wire management unit is disposed at the rear end of the connector drawer of the cabinet, and the opening thereof may be selectively covered by a cover plate (not shown) or another wire management unit, or may be open. As shown in fig. 1, the wire arranging unit of the present embodiment mainly includes a bottom plate 1, a plurality of side walls 2, a plurality of wire frames 3, a first limiting member 4, a second limiting member 5, a third limiting member 7, a plurality of partition plates 6, a fourth limiting member 8, and a plurality of

curved surface baffles

12, 13, 14, and 15.

In this example, the outer contour of the bottom plate 1 is a square shape without protrusions. But may be, for example, rectangular, etc., as desired. It should be noted that the outer contour of the bottom plate 1 may be concave, but the outer contour does not protrude from the rectangular frame, so the versatility is better.

In this embodiment, except that the plurality of wire frames 3 are subsequently fixed to the bottom plate, for example, the bottom plate 1, the plurality of side walls 2, the first limiting member 4, the second limiting member 5, the third limiting member 7, the fourth limiting member 8, the

curved surface baffles

12, 13, 14, 15 and other components are integrally formed by an injection molding process in the same mold, so that not only the closeness and strength of the wire management unit can be ensured, but also the cost can be reduced because the components do not need to be assembled, and the components are not limited to be integrally formed and can be assembled after being independently manufactured when necessary.

Referring to fig. 1, in this embodiment, four sidewalls 2 are disposed on a bottom plate 1 and enclose a receiving space. The four side walls 2 are provided with wire inlet and outlet ports 21 for communicating the accommodating space with the outside. As shown in fig. 1 and fig. 2, each sidewall 2 of the present embodiment includes two opposite ends, a gap is formed between one end of one sidewall 2 and the other sidewall 2 adjacent to the one end of the sidewall 2, the gap forms an inlet/outlet port 21, and a bending portion 22 bent inward toward the accommodating space is disposed at the end of each sidewall 2 opposite to the inlet/outlet port 21. In this embodiment, the bending portion 22 is a right-angle structure composed of a plurality of planes, but it may also be represented by a continuous curved surface, and the invention is not limited thereto.

More specifically, as shown in fig. 1, one end of the sidewall 2 has a bending portion 22 bent (deformed) toward the accommodating space to form an inwardly-retracted platform 23 outside the sidewall 2, the inwardly-retracted platform 23 is provided with a plurality of through holes 11, the plurality of through holes 11 respectively penetrate through the bottom plate 1, the through holes 11 can be used for penetrating a binding band 200, and the optical fiber harness 100 is fixed on the bottom plate 1 through the binding band 200. By arranging the inward-contracting platform 23 formed by the bending part 22 beside the through hole 11, a space for finger movement can be provided for a person wearing the strap 200, so that the person can conveniently wear the strap 200, and the efficiency of wearing the strap 200 is improved. Correspondingly, the side wall 2 of the other side of the inlet/outlet port 21 opposite to the bending portion 22 is closed, but may also be appropriately retracted (not shown), further increasing the activity space.

In addition, at least three of the plurality of side walls 2 of the present embodiment respectively include an inlet/outlet port 21, so that the wire arranging unit of the present embodiment has a plurality of inlet/outlet ports 21, which is convenient for the optical fiber harness 100 to enter the accommodating space from a plurality of different directions, and improves the versatility of the wire arranging unit. For example, as shown in fig. 1, the wire management unit of the present embodiment includes four sidewalls 2, the four sidewalls 2 form a square or rectangle, and each sidewall 2 has an inlet/outlet port 21.

In a modified design, taking fig. 1 as an example, the inlet/outlet 21 of the sidewall 2 at the lower left of fig. 1 may be disposed at the left end face of the sidewall 2 at the lower right so as to face the inlet/outlet 21 of the sidewall 2 at the upper left and be located on the same straight line. Meanwhile, the inlet/outlet ports 21 formed on the lower right side wall 2 of fig. 1 and located at the right side end face thereof may be alternatively arranged at the right side end face of the upper right side wall 2, that is, the upper right side wall 2 is respectively provided with two inlet/outlet ports 21 located at the left and right side end faces thereof. That is, in the modified design, three side walls 3 are provided with four inlet and outlet ports 21, and the wire arranging unit is horizontally mirrored along the middle line of the upper right and lower left.

As shown in fig. 1, a plurality of partition plates 6 may be further disposed at the inlet/outlet 21 of the wire management unit of this embodiment, and the plurality of partition plates 6 are disposed at intervals. The space between two adjacent partition plates 6 can accommodate the optical fiber wiring harness 100, so that the functions of separating the wiring harness and fixing the wiring harness are achieved, and the convenience of wire arrangement is further improved. Furthermore, the bottom plate 1 may further have a plurality of through holes 11 corresponding to the inlet/outlet ports 21, and the number of the plurality of through holes 11 may be selectively equal to the number of the partition plates 6 and aligned one by one.

In addition, as shown in fig. 1, the wire holder 3 is disposed in the opposite center of the accommodating space to fix the optical fiber fusion splices embedded therein, and the design of the wire holder 3 allows the optical fiber fusion splices to be stacked in multiple layers therein. Furthermore, the first limiting member 4, the second limiting member 5, the third limiting member 7, the fourth limiting member 8 and the curved surface baffles 12, 13, 14 and 15 are all 8 disposed on the bottom plate 1 and all located in the accommodating space, and the wiring frame 3 is located between the first limiting member 4 and the second limiting member 5 and between the third limiting member 7 and the fourth limiting member 8 and has a certain horizontal distance therebetween.

The side of the first limiting member 4 facing the wire connection frame 3 has a first curved surface for limiting the optical fiber harness 100, correspondingly, the side of the second limiting member 5 facing the wire connection frame 3 is called a second curved surface, and so on. Specifically, the first curved surface, the second curved surface, the third curved surface, and the fourth curved surface may be designed such that the central portion is farthest from the wire holder 3 and the left and right wings are gradually converged toward the wire holder 3, respectively. In addition, the top of the first limiting member 4, the second limiting member 5, the third limiting member 7 and the fourth limiting member 8 are respectively provided with an arc-shaped baffle plate horizontally extending towards the connection frame 3 for preventing the optical fiber harness 100 from sliding off from the top of each limiting member. In order to form the arc-shaped baffle plate by injection molding, a through hole is required to be reserved at the connection position of each limiting

member

4,5,7,8 and the bottom plate 1 so as to allow the arc-shaped baffle plate to be formed by using a mold. It should be emphasized that the first limiting member 4, the second limiting member 5, the third limiting member 7 and the fourth limiting member 8 mentioned in the present specification are defined functionally, and the first limiting member 4, the second limiting member 5, the third limiting member 7 and the fourth limiting member 8 are defined as either a structure/component (as shown in fig. 1) separately disposed from other components (for example, the side wall 2) or a part (not shown) of other components (for example, the side wall 2). That is, if the inner side of the sidewall 2 is provided with a curved surface corresponding to each of the position-limiting

members

4,5,7,8, the corresponding portion of the sidewall 2 is the position-limiting

member

4,5,7, 8. Referring to fig. 1, if necessary, any one or both of the first limiting member 4, the second limiting member 5, the third limiting member 7 and the fourth limiting member 8 included in the present embodiment may be omitted, for example, only the first limiting member 4 and the second limiting member 5 are left, and any one or both of the third limiting member 7 and the fourth limiting member 8 may be omitted.

In addition, in the prior art, the position of the wire is limited by a plurality of straight-plate type limiting members, the edges of the straight-plate type limiting members are in point-to-point contact with the optical fiber harness 100 to generate large stress, and by means of the curved surface design of the embodiment, the phenomenon that the optical fiber harness 100 naturally expands outwards in the arranging process is applied, so that the optical fiber harness 100 can be well attached to the curved surface of each limiting member and maintained. For example, when the curved surface of each limiting member corresponds to a circle, the radius of curvature of the first curved surface and the second curved surface is between 3 cm and 20cm, which provides a better maintaining effect for the optical fiber harness 100, and can greatly reduce the stress concentration on the optical fiber harness 100. In addition, when the length of each curved surface of each limiting member is greater than or equal to (not less than) 2cm, the effect can be further improved. Furthermore, the length of each curved surface of each limiting member refers to the shortest straight-line distance between any point on one end surface of the first curved surface and the second curved surface and any point on the other end surface.

It should be noted that, in addition to the strength of the cable itself, in the field of high-frequency electrical signal transmission, the stress concentration may cause the insulation of the cable to be stressed and extruded to deform, thereby generating impedance change, which may cause significant noise, so that the curved surface design of the present invention may have more significant advantages when applied to high-frequency electrical signal transmission. In addition, in this embodiment, the first limiting member 4, the second limiting member 5, the third limiting member 7, and the fourth limiting member 8 are located outside the optical fiber harness 100, that is, each of the limiting

members

4,5,7,8 applies a reaction force in the direction of the wire holder 3 to the optical fiber harness 100.

Specifically, as shown in fig. 1, the first curved surface and the second curved surface may be oppositely disposed, the third curved surface and the fourth curved surface may be oppositely disposed, and the third curved surface and the fourth curved surface may have substantially the same shape as the first curved surface and the second curved surface. The first curved surface, the second curved surface, the third curved surface and the fourth curved surface can be distributed along the periphery of the wiring frame 3 at equal intervals, and the improvement of the stress uniformity of the optical fiber wiring harness 100 is facilitated.

However, the present invention is not limited to this design, and as shown in fig. 2, in another embodiment, the third curved surface of the third limiting member 7 and the fourth curved surface of the fourth limiting member 8 have an offset with the central line of the wire holder 3 respectively. In other words, neither the third curved surface nor the fourth curved surface is located on the center line of the wire holder 3, but is disposed on one side of the center line thereof.

In the present invention, the length of the first curved surface and the length of the second curved surface may be the same or different (or different); the third curved surface and the fourth curved surface may have the same length or different lengths. In the illustration of fig. 2, the length of the first curved surface is the same as that of the second curved surface, but the length of the fourth curved surface is slightly longer than that of the third curved surface, but in the illustration of fig. 1, the lengths of the first curved surface, the second curved surface, the third curved surface and the fourth curved surface are the same.

Furthermore, a cable channel is formed between the first limiting member 4, the second limiting member 5, the third limiting member 7, and the fourth limiting member 8 and a corresponding

curved surface baffle

12, 13, 14, 15, respectively. The surface of each

curved surface baffle

12, 13, 14, 15 facing the corresponding limiting

member

4,5,7,8 is also curved, and the contour thereof can selectively correspond to or be different from the curved surface of the corresponding limiting

member

4,5,7, 8. Furthermore, a cylindrical structure (not shown) integrally formed with the base plate 1 may be optionally added between the

curved baffles

12, 13, 14, and 15 to serve as a structure for the optical fiber harness 100 to turn and enter the junction rack 3.

As shown in fig. 3, the usage of the wire management unit of this embodiment is as follows: when a person arranges the optical fiber bundle 100, the optical fiber bundle 100 bundled into a ring in advance is placed in the accommodating space, and after confirming that each part of the optical fiber bundle 100 is located in the cable channel, the optical fiber bundle can be naturally expanded outwards due to the stress of the optical fiber bundle and is abutted against each curved surface of each limiting

part

4,5,7,8 facing the wiring rack 3, so that each limiting part and each

curved surface baffle

12, 13, 14, 15 can position the optical fiber bundle 100 in the channel, and thus, the optical fiber bundle 100 can be simply maintained in the wire arranging unit. Of course, if the assembling personnel need to directly coil the cable in the cable arranging unit, the design of the cable arranging unit can also assist the assembling personnel to quickly complete the assembling operation.

Compared with the traditional wire arranging mode, in the wire arranging process, personnel only need to guide the optical fiber wire harness 100 to the corresponding curved surface and the clamping groove of the wire connection frame 3 without the need of individual clamping on the optical fiber wire harness 100, so that the wire arranging process of the personnel is greatly simplified, and the labor hour consumed by wire arranging is effectively saved.

The principle and the implementation mode of the invention are explained by applying specific embodiments in the invention, and the description of the embodiments is only used for helping to understand the method and the core idea of the invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present invention.
