Description

Technical Field

[0001] This utility model relates to the field of fiber optic splitter technology, specifically to a fiber optic splitter that prevents detachment. Background Technology

[0002] Fiber optic splitters are passive devices that distribute and combine optical signals, splitting a single input optical signal into multiple output signals or combining multiple input signals into a single output. They are commonly used in fiber optic access networks, local area networks (LANs), and fiber-to-the-home (FTTH) applications, often requiring frequent plugging and unplugging of fiber optic terminals for maintenance, upgrades, or line adjustments. However, many fiber optic splitters rely solely on simple plugging and unplugging to position and fix the fiber optic terminals. During this process, or due to accidental contact, terminals can easily become loose or slip off, leading to unstable optical signal connections, packet loss, or interruptions. This severely impacts the stability and transmission efficiency of the communication system, increases maintenance difficulty, and raises the risk of operational errors. Therefore, there is an urgent need for a fiber optic splitter that prevents detachment and addresses these technical shortcomings. Utility Model Content

[0003] The purpose of this invention is to provide an optical fiber splitter that prevents detachment, thereby solving the problems of loose terminals and high risk of signal interruption mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fiber optic splitter to prevent detachment, comprising a housing and a front panel. The front end of the housing is provided with three sets of connection ports, and terminal connectors are inserted into the connection ports. The ends of the terminal connectors are fiber bundles. The housing has a wall groove processed inside, and the wall groove has an anti-detachment structure. The anti-detachment structure includes a set of springs fixedly connected to the inner wall of the wall groove. The front end of the spring is fixedly connected to a movable block, and the bottom end of the movable block is fixedly connected to a connecting rod. The front end of the connecting rod abuts against two sets of clamping pieces. The inner side of the front end of the clamping pieces has a slot. A terminal sleeve is fixedly sleeved on the outside of the terminal connector, and the slot and the terminal sleeve form a snap-fit ​​connection.

[0005] As a further technical solution of this utility model, the connection port and the clip do not contact each other, and each set of clips is symmetrically distributed about the midpoint of the connection port.

[0006] As a further technical solution of this utility model, the clip has an "L" shape on its outer surface and is a component made of elastic plastic.

[0007] As a further technical solution of this utility model, the clip is movably connected to the box body, and a torsion spring is movably connected between the clip and the wall groove.

[0008] As a further technical solution of this utility model, each torsion spring is fitted with a gear at its bottom end, and two adjacent sets of gears are meshed and connected.

[0009] As a further technical solution of this utility model, the connection port is provided in three groups at the front end of the front panel, and the connection ports in each group are evenly distributed.

[0010] As a further technical solution of this utility model, an insulating ring is glued to the outer edge of the connection port, and the insulating ring is made of insulating rubber.

[0011] As a further technical solution of this utility model, handles are installed at all four corners of the front panel, and rubber sleeves are fitted over the handles.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the fiber optic splitter that prevents detachment not only achieves the fixed snap-fit ​​of the terminal connector without the need for additional tools, and achieves consistent opening or closing of the clips under stress, but also avoids the interface from being exposed and is not easily affected by dust and moisture.

[0013] (1) By setting an anti-drop structure, before inserting the fiber bundle, push the movable block towards the connecting rod to press the two sets of clips. The clips open outward under the action of the connecting rod, and the slot opens to form an insertion channel. At this time, align the terminal connector with the connection port and insert it. Then release the movable block. After the spring is released under pressure, it drives the connecting rod back to its original position. The torsion spring drives the clips to elastically rebound, and the clips quickly close. The slot locks the outer edge of the terminal sleeve, realizing the fixed snap-fit ​​of the terminal connector. No additional tools are required. The insertion and removal are efficient, and the snap-fit ​​is precise and firm. It solves the problems of loose and easy-to-fall-off terminals and high risk of signal interruption in traditional fiber optic splitters.

[0014] (2) By setting up clamps and gears, each set of clamps is movably connected to the bottom of the gears, and the two adjacent sets of gears mesh with each other through the tooth structure. During the process of pushing the movable block, the gears transmit the motion synchronously, so that the two sets of clamps open or close in the same way under the force, ensuring that the locking process is smooth, stable and not biased.

[0015] (3) By setting up a connection port and an insulating ring, each connection port is covered with an insulating ring on its outer edge. The insulating ring is a highly elastic insulating rubber ring. During the insertion of the terminal connector, it forms a tight fit with the outer wall of the terminal sleeve, isolating the electrical interference between the terminal contact part and the external metal parts. At the same time, it has a certain buffering performance to prevent the terminal from becoming loose or making poor contact due to the insertion and removal impact, and to avoid the interface part being exposed and not easily affected by dust and moisture.

[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] Please see Figure 1-4 The present invention provides an embodiment of an anti-detachment fiber optic splitter, comprising a housing 1 and a front panel 2. The front end of the housing 1 is provided with three sets of connection ports 14, and terminal connectors 12 are inserted into the connection ports 14. The end of the terminal connectors 12 is a fiber bundle 11. The housing 1 has a wall groove 3 processed inside, and the wall groove 3 has an anti-detachment structure. The anti-detachment structure includes a set of springs 4 fixedly connected to the inner wall of the wall groove 3. The front end of the springs 4 is fixedly connected to a movable block 5, and the bottom end of the movable block 5 is fixedly connected to a connecting rod 6. The front end of the connecting rod 6 abuts against two sets of clamping pieces 9. The inner side of the front end of the clamping pieces 9 is provided with a slot 10. The terminal connectors 12 are fixedly sleeved with terminal sleeves 13. The slots 10 and the terminal sleeves 13 form a snap-fit ​​connection. The connection ports 14 do not contact the clamping pieces 9. Each set of clamping pieces 9 is symmetrically distributed about the midpoint of the connection port 14.

[0023] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, before inserting the fiber bundle 11, push the movable block 5 towards the connecting rod 6, thereby pressing against the two sets of clamps 9. The clamps 9 open outward under the action of the connecting rod 6, and the slot 10 opens to form an insertion channel. At this time, align the terminal connector 12 with the connection port 14 and insert it. Then release the movable block 5. After the spring 4 is released from pressure, it drives the connecting rod 6 to return to its original position. The torsion spring 8 drives the clamps 9 to elastically rebound, and the clamps 9 quickly close. The slot 10 locks the outer edge of the terminal sleeve 13, thereby achieving the fixed snap-fit ​​of the terminal connector 12.

[0024] The clip 9 has an "L" shape on its surface. The clip 9 is a component made of elastic plastic. The clip 9 is movably connected inside the box 1. A torsion spring 8 is movably connected between the clip 9 and the wall groove 3. A gear 7 is sleeved at the bottom of each torsion spring 8. Two adjacent sets of gears 7 are meshed and connected.

[0025] Specifically, such as Figure 1 and Figure 3 As shown, each set of clamping plates 9 is movably connected to a gear 7 at its bottom. The two sets of gears 7 are meshed with each other through a toothed structure. During the process of pushing the movable block 5, the gears 7 transmit motion synchronously, so that the two sets of clamping plates 9 open or close in unison under the force.

[0026] Three sets of connection ports 14 are provided at the front end of the front panel 2. Each set of connection ports 14 is evenly distributed. An insulating ring 16 is glued to the outer edge of the connection port 14. The insulating ring 16 is made of insulating rubber. A handle 15 is installed at each of the four corners of the front panel 2. A rubber sleeve is fitted on the outside of the handle 15.

[0027] Specifically, such as Figure 1 and Figure 4 As shown, each set of connectors 14 is covered with an insulating ring 16 on its outer edge. The insulating ring 16 is a highly elastic insulating rubber ring that forms a tight fit with the outer wall of the terminal sleeve 13 during the insertion of the terminal connector 12, isolating the electrical interference between the terminal contact part and the external metal parts, and at the same time having a certain buffering performance to prevent the terminal from becoming loose or having poor contact due to the insertion and removal impact.

[0028] Working principle: Before inserting the fiber bundle 11, push the movable block 5 towards the connecting rod 6, thereby pressing against the two sets of clamps 9. Under the action of the connecting rod 6, the clamps 9 open outward, and the slot 10 opens to form an insertion channel. At this time, align the terminal connector 12 with the connection port 14 and insert it. Then release the movable block 5. After the spring 4 is released from pressure, it drives the connecting rod 6 to return to its original position. The torsion spring 8 drives the clamps 9 to elastically rebound, and the clamps 9 quickly close. The slot 10 locks the outer edge of the terminal sleeve 13, realizing the fixed engagement of the terminal connector 12. During the pushing of the movable block 5... During the process, the gear 7 transmits motion synchronously, so that the two sets of clamping plates 9 open or close in unison under force, ensuring that the engagement process is smooth, stable and without deviation. Each set of connection ports 14 is covered with an insulating ring 16. The insulating ring 16 is a highly elastic insulating rubber ring that forms a tight fit with the outer wall of the terminal sleeve 13 during the insertion of the terminal connector 12, isolating the electrical interference between the terminal contact part and the external metal parts, and at the same time having a certain buffering performance to prevent the terminal from becoming loose or having poor contact due to the insertion and removal impact, and to avoid the interface part being exposed.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
