Description

Technical Field

[0001] This utility model relates to the field of splitter technology, specifically a slotted optical cable splitter. Background Technology

[0002] Optical fiber is a flexible optical fiber, as thin as a hair, made of extremely pure glass or plastic. Its core structure consists of two layers: a central core and an outer cladding. The cladding has a slightly lower refractive index than the core. Utilizing the principle of total internal reflection, it confines the optical signal within the core and transmits it over long distances like water flowing through a pipe. It has outstanding advantages such as large transmission capacity, low loss, resistance to electromagnetic interference, and strong security, making it the backbone of modern communication networks.

[0003] Chinese patent CN223284432U discloses a communication optical cable splitter. The splitter includes a housing with an inlet hole at one end and a connecting shell connected to the other end via a thread. A splitter plate is snap-fitted to the other end of the connecting shell. A snap-fit ​​assembly is assembled between the connecting shell and the splitter plate. A first splitter hole is formed on the side wall of the splitter plate. Different diameter first and second splitter holes are formed on the side wall of the splitter plate. During use, a splitter plate with the corresponding hole diameter is selected according to the specific needs of cable splitting to connect and fix it to the connecting shell. The splitter plate and the connecting shell are connected and fixed using a snap-fit ​​assembly. The snap-fit ​​assembly makes the connection and disassembly between the splitter plate and the connecting shell simpler and more convenient. This not only improves the efficiency of cable splitting during cable laying but also makes the disassembly of the splitter plate simpler and faster during maintenance and repair of the splitter point.

[0004] While the aforementioned splitter can improve cable splitting efficiency, both the main and branch cables lack fixing. During use, when any cable is pulled by external force, the resulting stress is directly transmitted to other cables through the splitting hole, causing them to pull on each other. This chain reaction of pulling can easily lead to displacement or loosening of other cables, and even damage to the internal optical fibers, seriously affecting the long-term stability and reliability of the splitting point. Utility Model Content

[0005] The purpose of this invention is to provide a slotted optical cable splitter to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows.

[0007] A slotted optical cable splitter includes a housing. A main cable pass-through hole is formed on one side of the housing. A main sleeve is disposed outside the main cable pass-through hole. Multiple first clamps are flexibly connected to the ends of the main sleeve. The first clamps have a trapezoidal cross-section with a bottom plane and an upper inclined plane. External threads are provided on the outer surface of the first clamps. Nuts are fitted onto the outer surface of the main sleeve. Multiple branch cable pass-through holes are formed on the other side of the housing. Branch sleeves are disposed outside the branch cable pass-through holes. Multiple second clamps are flexibly connected to the ends of the branch sleeves. The second clamps have a trapezoidal cross-section with a bottom plane and an upper inclined plane. A retraction mechanism is shared on the outer sides of the multiple branch sleeves to simultaneously retract the multiple sets of second clamps inward.

[0008] Therefore, by rotating the nut onto the first clamp, multiple first clamps can retract inward and clamp onto the main optical cable. The retraction mechanism drives multiple sets of second clamps to retract inward and clamp onto the branch optical cable simultaneously. This allows the main optical cable and the branch optical cable to be fixed separately, preventing the pulling of one optical cable from affecting other optical cables and ensuring the long-term stability and reliability of the branching point.

[0009] Furthermore, the shrinking mechanism includes a limiting ring fitted onto the outer surface of the support sleeve. Adjacent limiting rings are connected by a connecting plate. A screw is threaded through and connected to the interior of the connecting plate in the middle. The end of the screw is rotatably connected to the outer surface of the housing. Rotating the screw can drive multiple limiting rings to slide simultaneously toward each set of second clamping plates, realizing rapid clamping of the optical cable.

[0010] Furthermore, guide rods are slidably installed inside the connecting plates on both sides, with the ends of the guide rods connected to the outer surface of the housing. This allows the connecting plates and the limiting rings to move more smoothly.

[0011] Furthermore, an L-shaped block is installed at the other end of the guide rod. A stop bar is vertically slidably installed inside the crossbar of the L-shaped block. A shoulder is provided on the outer surface of the stop bar, and a spring is fitted on the outer surface of the stop bar. The two ends of the spring abut against the shoulder and the crossbar of the L-shaped block, respectively. The stop bar is used to abut against the rear of the connecting plate to prevent the support sleeve from sliding backward on the second clamp.

[0012] Furthermore, beveled slots are provided on both sides of the connecting plate, corresponding to the stop bar. This allows the stop bar to automatically rise and fall back behind the connecting plate during the rotation of the screw.

[0013] Furthermore, both the first and second clamping plates have rubber pads on their inner walls, and the surfaces of the rubber pads are textured with anti-slip patterns. This enhances the clamping effect on the optical cable.

[0014] Furthermore, the outer surface of the nut is provided with multiple levers. This facilitates better rotation of the nut to drive the first clamping plate to clamp the main optical cable.

[0015] Furthermore, it includes a cover, which is screwed onto the top of the housing. This provides physical protection for the branching point and reduces interference from the external environment.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0017] 1. This utility model, by rotating the nut onto the first clamp, allows multiple first clamps to retract inward and clamp onto the main optical cable. The retraction mechanism drives multiple sets of second clamps to retract inward simultaneously and clamp onto the branch optical cable, thereby fixing the main optical cable and the branch optical cable separately. This prevents the situation where pulling on one optical cable will affect other optical cables, ensuring the long-term stability and reliability of the branching point.

[0018] 2. This utility model uses a stop bar to block the rear side of the connecting plate, which can effectively prevent the support sleeve from sliding backward on the second clamp and causing the second clamp to loosen its grip on the optical cable, thus further ensuring the long-term stability and reliability of the optical cable.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-5 As shown, a slotted optical cable splitter includes a housing 1. A main cable pass-through hole 101 is provided on one side of the housing 1. A main sleeve 102 is provided outside the main cable pass-through hole 101. Multiple first clamps 103 are flexibly connected to the end of the main sleeve 102. The cross-section of each first clamp 103 is a trapezoidal structure with a bottom plane and an upper inclined plane. External threads are provided on the outer surface of each first clamp 103. A nut 104 is fitted onto the outer surface of the main sleeve 102. Multiple branch cable pass-through holes 105 are provided on the other side of the housing 1. A branch sleeve 106 is provided outside the branch cable pass-through hole 105. Multiple second clamps 107 are flexibly connected to the end of each branch sleeve 106. The cross-section of each second clamp 107 is a trapezoidal structure with a bottom plane and an upper inclined plane. A retraction mechanism 2 is provided on the outer side of the multiple branch sleeves 106 to simultaneously retract the multiple sets of second clamps 107 inwards.

[0023] In use, the main optical cable is passed through the main sleeve 102 into the housing 1. After splitting, multiple branch optical cables are passed through multiple branch insertion holes 105 and branch sleeves 106 respectively. Then, the nut 104 is rotated to screw it into the external thread of the first clamp 103. Since the outer side of the first clamp 103 is a beveled structure, under the pressure of the nut 104, multiple first clamps 103 will simultaneously retract inward and clamp onto the main optical cable, thus fixing the main optical cable. Then, the retraction mechanism 2 simultaneously drives multiple sets of second clamps 107 to retract inward and clamp onto the branch optical cables, thereby fixing the main optical cable and branch optical cables separately. This prevents the situation where pulling one optical cable will affect other optical cables, ensuring the long-term stability and reliability of the splitting point.

[0024] Preferably, the shrinking mechanism 2 includes a limiting ring 201 sleeved on the outer surface of the support sleeve 106. Two adjacent limiting rings 201 are connected by a connecting plate 202. A screw 203 is threaded through and connected to the interior of the connecting plate 202 in the middle. The end of the screw 203 is rotatably connected to the outer surface of the housing 1.

[0025] When the screw 203 is rotated, the threaded connection will cause multiple limiting rings 201 and multiple connecting plates 202 to move outward simultaneously. Since the outer side of the second clamping piece 107 is a sloping structure, it can shrink inward and clamp onto the optical cable under the pressure of the limiting ring 201 to complete the fixation. Since it can fix multiple optical cables at the same time, the operation efficiency is high.

[0026] Preferably, a guide rod 3 is slidably provided inside the connecting plate 202 on both sides, and the end of the guide rod 3 is connected to the outer surface of the housing 1.

[0027] The guide rod 3 provides a limiting and guiding function for the connecting plate 202, enabling the connecting plate 202 and the limiting ring 201 to move more smoothly.

[0028] Preferably, an L-shaped block 301 is installed at the other end of the guide rod 3. A stop rod 302 is vertically slidably disposed inside the crossbar of the L-shaped block 301. A shoulder 303 is provided on the outer surface of the stop rod 302. A spring 304 is sleeved on the outer surface of the stop rod 302. The two ends of the spring 304 abut against the shoulder 303 and the crossbar of the L-shaped block 301, respectively. Inclined slots 305 are provided on the connecting plates 202 on both sides, and the inclined slots 305 correspond to the stop rods 302.

[0029] When the rotating screw 203 drives the connecting plate 202 to move towards the second clamping piece 107, the inclined groove 305 will contact the bottom of the stop bar 302. Under the action of the squeezing force, the stop bar 302 moves upward and drives the shoulder 303 to compress the spring 304, so that the connecting plate 202 can automatically move to the rear of the stop bar 302. When the stop bar 302 loses the squeezing action of the inclined groove 305 and the connecting plate 202, it can be pushed down by the spring 304 to reset and block the rear of the connecting plate 202, which can play a role in preventing backward movement. This can effectively prevent the support sleeve 106 from sliding backward on the second clamping piece 107 and causing the second clamping piece 107 to loosen its clamping effect on the optical cable, further ensuring the long-term stability and reliability of the optical cable.

[0030] Preferably, the inner walls of the first clip 103 and the second clip 107 are provided with rubber pads, and the surface of the rubber pads is provided with anti-slip texture.

[0031] The rubber pads and anti-slip texture not only increase the clamping effect on the optical cable, but also the flexible contact can avoid damage to the optical cable, thus ensuring the communication quality of the optical cable.

[0032] Preferably, the outer surface of the nut 104 is provided with a plurality of levers 5.

[0033] The addition of a hand grip point facilitates better rotation of the nut 104, which in turn drives the first clamping plate 103 to clamp the main optical cable.

[0034] Preferably, it also includes a cover 4, which is mounted on the top of the housing 1 by screws.

[0035] By installing the cover 4 on the top of the housing 1, physical protection can be provided for the branch point, reducing interference from the external environment.

[0036] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, which will not be described in detail here.
