Description

Technical Field

[0001] The utility model belongs to the technical field of cables, and particularly relates to a cable transition structure. Background Art

[0002] In high-speed cable applications (such as four-channel small form-factor pluggable cables (QSFP)), an installer picks up a multi-conductor cable, opens one end of it and exposes the internal conductors by a certain predetermined length to form a cable branch structure with multiple free ends of conductors, and in QSFP applications, usually four free ends of conductors are formed. This branching from a main cable to a multi-conductor small form-factor pluggable (SFP) branch cable occurs in a transition area. When these conductors are connected to their corresponding connectors, it is important to provide some strain relief for this branch structure to prevent these conductors from being damaged. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a cable transition structure with a simple structure and reasonable design to solve the above problems.

[0004] The utility model realizes the above purpose through the following technical solutions:

[0005] A cable transition structure includes a protective shell, and a plurality of positioning components are uniformly arranged on the inner side wall of the protective shell. Each of the plurality of positioning components includes a positioning ring fixedly connected to the inner side wall of the protective shell, and a locking component for fixing the branch cable is arranged on one side of the positioning ring.

[0006] As a further optimized scheme of the utility model, the locking component includes a threaded sleeve fixedly arranged on one side of the positioning ring, a positioning screw is threadedly sleeved inside the threaded sleeve, and an arc-shaped positioning plate located inside the positioning ring is arranged at one end of the positioning screw.

[0007] As a further optimized scheme of the utility model, a rubber ring matching with the branch cable is arranged on the inner side wall of the positioning ring.

[0008] As a further optimized scheme of the utility model, the protective shell adopts a hollow frustum structure.

[0009] As a further optimized scheme of the utility model, a bottom plate is integrally arranged at the small port of the protective shell, and a wire inlet hole is opened at the center of the bottom plate.

[0010] As a further optimized scheme of the utility model, a cover plate is covered at the large port of the protective shell. A plurality of wire outlet holes matching with the positioning rings are opened on the cover plate. A plurality of first positioning plates are arranged around the cover plate, and a plurality of second positioning plates matching with the first positioning plates are arranged at the edge of the large port of the protective shell. The first positioning plates and the second positioning plates are fixed by bolts.

[0011] The beneficial effects of the present utility model are as follows: In the present utility model, through the integrally formed protective shell, the strength of the protective shell can be improved, so that the branch cables inside the protective shell play a good protective role. And by arranging multiple groups of positioning components inside the protective shell, each branch cable is fixed, preventing multiple branch cables from winding around each other, which makes it inconvenient for subsequent maintenance of the cables. Moreover, the multiple branch cables are separately fixed, preventing the damage of one branch cable from affecting the operation of other branch cables and improving the working life of the branch cables.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following further describes the present application in detail with reference to the drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0017] Embodiment

[0018] As Figure 1 、 Figure 3As shown in the figure, a cable transition structure includes a protective shell 1. The protective shell 1 adopts a hollow frustum structure. A bottom plate 3 is integrally provided at the small port of the protective shell 1. An inlet hole 4 is opened at the center of the bottom plate 3. A plurality of positioning components 2 are evenly arranged on the inner side wall of the protective shell 1. Each of the plurality of positioning components 2 includes a positioning ring 201 fixedly connected to the inner side wall of the protective shell 1. A locking component for fixing the branch cable is arranged on one side of the positioning ring 201. The locking component includes a threaded sleeve 203 fixedly arranged on one side of the positioning ring 201. A positioning screw 202 is threadedly sleeved inside the threaded sleeve 203. One end of the positioning screw 202 is provided with an arc-shaped positioning plate 204 located inside the positioning ring 201. During use, by passing the branch cable through the positioning ring 201 and then rotating the positioning screw 202, the arc-shaped positioning plate 204 can be moved to fix the branch cable inside the positioning ring 201, preventing multiple branch cables from being wound together and facilitating maintenance by personnel. A rubber ring 205 matching the branch cable is arranged on the inner side wall of the positioning ring 201. During use, through the rubber ring 205, it is possible to prevent damage to the branch cable when the branch cable is fixed by extrusion.

[0019] On the basis of the above solution, a further improvement is that, as Figure 2 shown, a cover plate 5 is covered and arranged at the large port of the protective shell 1. A plurality of outlet holes 6 matching the positioning rings 201 are opened on the cover plate 5. During use, the cover plate 5 can seal one end of the protective shell 1 to prevent dust from entering the interior of the protective shell 1 and affecting the operation of the branch cable. Through the plurality of outlet holes 6, multiple branch cables can be separated and operate independently, improving the efficiency of the cable. A plurality of first positioning plates 7 are arranged around the cover plate 5. A plurality of second positioning plates 8 matching the first positioning plates 7 are arranged at the edge of the large port of the protective shell 1. The first positioning plates 7 and the second positioning plates 8 are fixed by bolts, so that the cover plate 5 can seal the large port of the protective shell 1 to prevent external objects from affecting the working stability of the branch cable inside the protective shell 1.

[0020] It should be noted that for this cable transition structure, during use, one end of the main line of the multi-conductor cable is passed through the inlet hole 4, and then the branch ends of the multi-conductor cable are respectively passed through different positioning rings 201. Then the positioning screw 202 is rotated, so that the arc-shaped positioning plate 204 at one end of the positioning screw 202 fixes the branch cable inside the positioning ring 201, fixing multiple branch cables. Finally, the multiple branch cables are passed through the outlet holes 6 on the cover plate 5, and then the branch cables are connected to the corresponding connectors to prevent damage to the cable during branching.

[0021] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all fall within the protection scope of the present utility model.
