Description

Technical Field

[0001] This utility model belongs to the field of network construction technology, and in particular relates to a multi-core splitter. Background Technology

[0002] As fiber optic user networks rapidly evolve towards higher density and larger capacity, the number of optical cable cores continues to increase, upgrading from the traditional 4-core and 8-core to 16-core, 32-core, and even higher specifications to meet diverse communication needs such as multi-user concurrent access, high-definition video transmission, and IoT data interaction. Against this backdrop, the splitter, as a core component for optical cable core splitting and node connection, directly impacts the construction efficiency and long-term operational stability of fiber optic networks due to the ease and reliability of its core splitting operation. Therefore, the market demand for efficient splitting solutions compatible with multi-core optical cables is becoming increasingly urgent.

[0003] Currently, during network construction, after the outer sheath of the optical cable is stripped, multiple cores are easily tangled up inside the casing. Construction workers need to identify the core numbers one by one and manually arrange them, which not only consumes a lot of time, but also easily leads to incorrect connection faults due to the confusion of cores.

[0005] This utility model is implemented as follows: a multi-core splitter includes: a housing; a bracket disposed within the housing; a faceplate fixed to the housing by bolts for limiting the position of the bracket; a plurality of hollow tubes disposed within the bracket for separating optical fiber cores, one end of each hollow tube extending beyond the faceplate; and a waterproof mechanism disposed at the tail end of the housing for inserting an optical cable.

[0006] Preferably, the waterproof mechanism includes: a washer disposed at the tail end of the housing; a clamping nut threaded onto the tail end of the housing; a clamping cap threaded onto the clamping nut, wherein the clamping cap is provided with a sealing ring and clamping claws for the optical cable to pass through; and a tightening nut threaded onto the clamping cap.

[0007] Preferably, a waterproof ring is provided between the cover and the bracket to seal the gap and prevent water from entering, and a threaded groove is provided on the housing, which is adapted to the bolt.

[0008] Preferably, the cover has a plurality of insertion holes arranged in an elliptical array, and the insertion holes are adapted to the empty tube.

[0009] Preferably, the inner wall of the bracket is provided with a plurality of axially extending partition ribs, which divide the interior of the bracket into a plurality of independent mounting cavities, which are adapted to the hollow tube.

[0010] Preferably, the inner wall of the housing is provided with an annular positioning protrusion at the bottom position of the bracket, and the bottom of the bracket is provided with an annular positioning groove that matches the annular positioning protrusion.

[0011] Preferably, the cover is further provided with a mounting hole, the inner wall of which is provided with an internal thread, and the specification of the internal thread matches the external thread of the bolt.

[0012] Compared with related technologies, the multi-core splitter provided by this utility model has the following beneficial effects:

[0013] The independent mounting cavity formed by the internal partition ribs of the bracket adapts to the empty tube, and together with the elliptical array of insertion holes on the cover, it forms multiple layers of separation and guidance for the fiber optic cores, reducing the tangled cores and lowering the probability of incorrect connection failures, while simplifying the operation process for construction personnel. Through the coordinated sealing of the gaskets, sealing rings, and clamping claws in the waterproof mechanism at the tail end of the shell, combined with the waterproof ring between the cover and the bracket, external moisture infiltration is blocked from multiple points, providing reliable protection for the cores inside the shell.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides a multi-core brancher, such as Figure 1-6 As shown, the multi-core splitter includes: a housing 1; a bracket 5 disposed within the housing 1; a faceplate 2 fixed to the housing 1 by bolts 7 for limiting the bracket 5; and a plurality of hollow tubes 4 disposed within the bracket 5 for separating the optical fiber cores, one end of each hollow tube 4 extending out of the faceplate 2, and a waterproof mechanism disposed at the tail end of the housing 1 for inserting an optical cable 8.

[0023] In this embodiment, several empty tubes 4 are first installed into the bracket 5, and then the bracket 5 is placed into the housing 1. Then, the cover 2 is placed on the housing 1, and the bolts 7 are passed through the mounting holes of the cover 2 and threaded into the housing 1. The tightening of the bolts 7 causes the cover 2 to limit and fix the bracket 5. Next, the optical cable 8 is inserted into the housing 1 through the waterproof mechanism at the tail end of the housing 1. After the outer sheath of the optical cable 8 is stripped, the exposed multiple optical fiber cores are respectively inserted into the empty tubes 4 in the bracket 5. The part of the empty tube 4 extending out of the cover 2 provides an extension channel for the subsequent connection of the cores.

[0024] The empty tubes 4 inside the bracket 5 separate the optical fiber cores, preventing the cores from becoming tangled and messy inside the housing 1. Construction workers do not need to manually arrange the cores after identifying their serial numbers one by one; they can directly insert the cores according to the position of the empty tubes 4, reducing operation steps and time consumption. At the same time, the waterproof mechanism at the end of the housing 1 can seal the insertion position of the optical cable 8, reducing the probability of external moisture entering the housing 1 and providing protection for the cores.

[0025] Bolt 7 connects the faceplate 2 and the housing 1 to maintain a stable assembly state, thereby keeping the bracket 5 and the empty tube 4 fixed in position and reducing the possibility of wire core displacement due to structural loosening during use; the separation function of the empty tube 4 reduces the possibility of wire core confusion leading to incorrect connection failure, improves the stability of multi-core splitter in network construction, and adapts to the branch connection requirements of multi-core optical cables.

[0026] In a further preferred embodiment of the present invention, the waterproof mechanism includes: a washer 9 disposed at the tail end of the housing 1; a clamping nut 10 threadedly mounted on the tail end of the housing 1; a clamping cap 12 threadedly mounted on the clamping nut 10, wherein the clamping cap 12 is provided with a sealing ring 11 and a clamping claw 13 through which the optical cable 8 can pass; and a tightening nut 14 threadedly mounted on the clamping cap 12.

[0027] In this embodiment,

[0028] First, fit the washer 9 onto the tail end of the housing 1, then thread the clamping nut 10 onto the tail end of the housing 1, so that the washer 9 is clamped between the tail end of the housing 1 and the clamping nut 10, forming a preliminary seal; then, place the sealing ring 11 and clamping claw 13 into the inside of the clamping cap 12 in sequence, then thread the clamping cap 12 onto the clamping nut 10, and finally thread the tightening nut 14 onto the end of the clamping cap 12 away from the clamping nut 10, to complete the overall assembly of the waterproof mechanism;

[0029] The optical cable 8 is passed sequentially through the tightening nut 14, clamping claw 13, sealing ring 11, compression cap 12, compression nut 10, and washer 9 until the optical cable 8 extends into the housing 1. The tightening nut 14 is rotated, and the tightening nut 14 moves towards the compression cap 12, causing the clamping claw 13 to retract, so that the clamping claw 13 fits tightly against the outer wall of the optical cable 8, thus fixing the optical cable 8. At the same time, the retraction of the clamping claw 13 pushes the sealing ring 11 to further compress and deform, enhancing the fit between the sealing ring 11 and the inner wall of the optical cable 8 and the compression cap 12.

[0030] Waterproofing effect and applicability: The fit between the gasket 9 and the tail end of the housing 1 and the clamping nut 10 can prevent external moisture from seeping in through the connection gap between the housing 1 and the clamping nut 10; the synergistic effect of the sealing ring 11 and the clamping claw 13 can provide multiple seals at the insertion position of the optical cable 8, reducing the probability of moisture entering the interior of the housing 1 along the outer wall of the optical cable 8.

[0031] In a further preferred embodiment of this utility model, a waterproof ring 6 is provided between the cover 2 and the bracket 5 to seal the gap and waterproof the surface. A threaded groove is provided on the housing 1, and the threaded groove is adapted to the bolt 7.

[0032] In this embodiment, the waterproof ring 6 is placed on the side of the bracket 5 facing the face cover 2, so that the waterproof ring 6 is aligned with the edge contour of the bracket 5; then the bracket 5 equipped with the waterproof ring 6 is placed inside the housing 1, and the position of the bracket 5 is adjusted so that it fits against the inner wall of the housing 1, in preparation for the subsequent installation of the face cover 2. This process can initially position the waterproof ring 6 through the structure of the bracket 5 itself, so as to avoid the waterproof ring 6 from shifting during assembly.

[0033] The cover is bolted to the housing: Cover the top of the housing 1 with the cover 2, so that the inside of the cover 2 contacts the waterproof ring 6 on the bracket 5; then pass the bolt 7 through the mounting hole of the cover 2, align it with the threaded groove on the housing 1 and screw it in gradually. As the bolt 7 is tightened, it moves the cover 2 closer to the housing 1, so that the waterproof ring 6 is squeezed between the cover 2 and the bracket 5, gradually filling the gap between the two.

[0034] The compressed waterproof ring 6 can fit the contact surface between the cover 2 and the bracket 5, preventing external moisture from seeping into the housing 1 through the gap between the cover 2 and the bracket 5, thus providing protection for the optical fiber core inside the housing. At the same time, the fitting connection between the bolt 7 and the threaded groove of the housing 1 keeps the cover 2 and the housing 1 in a stable assembly state, thereby providing a reliable limit for the bracket 5, reducing the possibility of displacement of the bracket 5 due to vibration during use, and maintaining the separation effect of the hollow tube 4 on the optical fiber core.

[0035] In a further preferred embodiment of the present invention, the cover 2 is provided with a plurality of insertion holes 3, which are arranged in an elliptical array and are adapted to the empty tube 4.

[0036] In this embodiment, several empty tubes 4 inside the bracket 5 are aligned with the insertion holes 3 on the faceplate 2, and the bracket 5 is pushed towards the faceplate 2 so that one end of the empty tube 4 is gradually inserted into the corresponding insertion hole 3. Since the insertion hole 3 and the empty tube 4 are compatible, the empty tube 4 can maintain a stable posture during the insertion process without repeated adjustment of its position until the empty tube 4 extends out of the insertion hole 3, thus completing the initial assembly of the empty tube 4 and the faceplate 2.

[0037] Core insertion and arrangement guidance: After the outer sheath of the optical cable 8 is stripped to expose the optical fiber core, the construction personnel can insert each core into the corresponding empty tube 4 extending from the cover 2. The empty tube 4 is fixed in position by the cooperation of the insertion hole 3 and the cover 2, providing a clear channel for the core insertion; at the same time, several insertion holes 3 are distributed in an elliptical array, so that multiple empty tubes 4 are arranged in a regular manner, avoiding the core from becoming messy and tangled after insertion;

[0038] The matching structure between the socket 3 and the empty tube 4 can reduce the offset of the empty tube 4 in the bracket 5, ensure that each empty tube 4 corresponds to an independent core channel, and reduce the probability of incorrect connection caused by core confusion; the socket 3 distributed in an elliptical array can be reasonably planned and laid out according to the number of cores of the multi-core optical cable, and realize the orderly installation of multiple empty tubes 4 within the limited space of the cover 2.

[0039] In a further preferred embodiment of the present invention, the inner wall of the bracket 5 is provided with a plurality of axially extending partition ribs, which divide the interior of the bracket 5 into a plurality of independent mounting cavities, and the mounting cavities are adapted to the hollow tube 4.

[0040] In this embodiment, several empty tubes 4 are respectively aligned with the independent mounting cavities formed by the partition ribs inside the bracket 5. Then, the empty tubes 4 are gradually inserted along the axial direction of the mounting cavity. Since the mounting cavity and the empty tubes 4 are compatible, the empty tubes 4 can move along the inner wall of the mounting cavity during the insertion process. The partition ribs can guide the position of the empty tubes 4 to avoid the empty tubes 4 from shifting or tilting inside the bracket 5 until the empty tubes 4 are completely placed in the mounting cavity, thus completing the initial assembly of the empty tubes 4 and the bracket 5.

[0041] After the outer sheath of the optical cable 8 is stripped to expose multiple optical fiber cores, each core is inserted into the hollow tube 4 in the mounting cavity of the bracket 5. The separator ribs isolate different hollow tubes 4 through independent mounting cavities, so that the cores inserted into the hollow tubes 4 remain independent, reducing the possibility of cores contacting or tangling with each other inside the shell. Construction personnel do not need to manually adjust the spacing of the cores and can directly complete the core insertion according to the distribution of the mounting cavities, simplifying the operation process.

[0042] The partition ribs and bracket 5 are integrated into one structure, which can enhance the overall strength of bracket 5 and reduce the probability of deformation during assembly or use. At the same time, the independent mounting cavity limits the empty tube 4, which can maintain the stability of the empty tube 4 in the bracket 5 and prevent the empty tube 4 from shifting when the optical cable 8 is pulled by force. This reduces the possibility of connection failure of the core due to the displacement of the empty tube 4, and is suitable for the long-term use of multi-core optical cables.

[0043] In a further preferred embodiment of the present invention, an annular positioning protrusion is provided on the inner wall of the housing 1 at the bottom position corresponding to the bracket 5, and an annular positioning groove adapted to the annular positioning protrusion is provided on the bottom of the bracket 5.

[0044] In this embodiment, the matching and cooperation of the annular positioning protrusion and the annular positioning groove can restrict the circumferential rotation of the bracket 5 within the housing 1, so that the mounting cavity within the bracket 5 always corresponds to the insertion hole 3 on the cover 2. When installing the cover 2 later, there is no need to repeatedly calibrate the relative position of the bracket 5 and the cover 2. The cover 2 can be directly placed on the housing 1 to achieve the alignment of the empty tube 4 and the insertion hole 3, reducing assembly time and improving operational efficiency.

[0045] In a further preferred embodiment of the present invention, the cover 2 is also provided with an installation hole, the inner wall of the installation hole is provided with an internal thread, and the specification of the internal thread matches the external thread of the bolt 7.

[0046] In this embodiment, after the initial assembly of the bracket 5 and the waterproof ring 6 is completed, the cover 2 is placed on the housing 1, so that the mounting hole of the cover 2 is aligned with the thread groove of the housing 1; then the bolt 7 is aligned with the mounting hole. Since the internal thread of the mounting hole matches the external thread of the bolt 7, rotating the bolt 7 will allow the bolt 7 to be gradually screwed into the mounting hole along the internal thread until the end of the bolt 7 contacts the thread groove of the housing 1, laying the foundation for subsequent fixing operations.

[0047] Continue rotating bolt 7. Bolt 7 moves towards housing 1 through the engagement of internal and external threads, causing face cover 2 to gradually approach housing 1, so that face cover 2 generates a stable limiting force on bracket 5. During this process, the engagement method of the threaded connection can be adjusted by controlling the screwing depth of bolt 7, thereby adjusting the limiting force of face cover 2 on bracket 5, avoiding the bracket 5 from shifting due to excessively loose limiting, or the component from deforming due to excessively tight limiting.

[0048] In summary, compared with related technologies, this utility model, through the independent mounting cavity formed by the internal partition ribs of the bracket 5 and its adaptation to the empty tube 4, combined with the elliptical array of insertion holes 3 on the cover 2, forms multiple layers of separation and guidance for the optical fiber core, reducing the messy tangling of the core and lowering the probability of incorrect connection failures, while simplifying the operation process for construction personnel; through the coordinated sealing of the gasket 9, sealing ring 11, and clamping claw 13 in the waterproof mechanism at the tail end of the housing 1, combined with the waterproof ring 6 between the cover 2 and the bracket 5, external moisture infiltration is blocked from multiple points, providing reliable protection for the core inside the housing 1; through the adaptation of the annular positioning protrusion on the inner wall of the housing 1 and the annular positioning groove at the bottom of the bracket 5, combined with the precise connection of the internal thread and bolt 7 in the mounting hole of the cover 2, stable assembly of the bracket 5, cover 2, and housing 1 is achieved, reducing the risk of component displacement, ensuring long-term stability, and comprehensively adapting to the branch connection requirements of multi-core optical cables, improving network construction efficiency and equipment reliability, and solving the problems of inconvenient core arrangement, insufficient waterproof performance, and low assembly efficiency in the construction of multi-core optical cables.
