Description

Technical Field

[0001] This utility model belongs to the field of optical fiber core splicing technology, and in particular relates to an optical fiber core splicing position fixer. Background Technology

[0002] The fiber optic core is the core component of an optical cable, primarily made of high-purity quartz glass. Its main function is to transmit optical signals. With the continuous development and widespread adoption of internet network technology, network cabling needs to be relocated. This relocation involves splicing fiber optic cores. To ensure stable splices, fasteners are used to secure the splice positions.

[0003] Chinese utility model patent with publication number CN210038230U discloses an optical fiber core splice position fixer that can fix the optical fiber core splice position without heating, effectively improve the splice speed, ensure the splice quality, reduce the cost investment for various operators, standardize the network construction principles in various scenarios, reduce investment costs, solve the communication interruption problem caused by urban pipeline relocation, reduce user complaints, improve the quality of communication services and user experience, and save manpower and money to develop new networks.

[0004] However, the aforementioned fixers are difficult to apply to fiber optic splices of various types and diameters, affecting the applicability and practicality of the device. Furthermore, the lack of a positioning structure and the simple snap-fit ​​method result in instability and easy detachment, impacting the stability of the fiber optic splice. Therefore, there is an urgent need to improve existing fiber optic splice position fixers to provide a more widely applicable one. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a reasonably designed, simple, widely applicable, and more stable optical fiber splice positioning optical fiber core splice fixer, thereby solving the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fiber optic cable core splice position fixer includes a fixed base plate. Bolt mounting holes are provided inside both the left and right ends of the fixed base plate. A lower positioning seat is fixedly connected to the upper center of the fixed base plate. An upper positioning seat is provided directly above the lower positioning seat. Positioning holes are provided inside both the lower and upper positioning seats. Flexible clamping components for clamping the optical cable are installed on the inner sides of both the lower and upper positioning seats. Two toothed racks are symmetrically fixed at the bottom of the left and right ends of the upper positioning seat. Two mounting slots are respectively provided inside the left and right ends of the lower positioning seat. The lower ends of the two toothed racks are respectively inserted into the two mounting slots and positioned by the positioning components provided in the mounting slots.

[0008] Preferably, both the lower positioning seat and the upper positioning seat have a concave cross-section, and the lower positioning seat and the upper positioning seat form a disassembly structure with the two sets of flexible clamping components.

[0009] Preferably, the flexible clamping assembly includes a rubber block, positioning elements, grooves, an adhesive layer, and release paper. Positioning elements are bonded to the four right angles on one side of the rubber block, and grooves are equally spaced along the horizontal direction on the other side of the rubber block. An adhesive layer is uniformly coated on the surface of the side of the rubber block with grooves, and release paper covers the surface of the adhesive layer.

[0010] Preferably, the number of positioning holes inside the lower and upper positioning seats is equal to the number of positioning components.

[0011] Preferably, the positioning element is made of elastic rubber, and its longitudinal section is umbrella-shaped and adapted to the positioning hole.

[0012] Preferably, the meshing structure of the two racks is located on opposite sides of each other, and the bottom end of the rack extends into the lower positioning seat and is slidably connected to the lower positioning seat.

[0013] Preferably, the positioning component includes a paddle, a handle, and a support spring. The paddle is rotatably mounted on the inner side of the mounting groove, and a rubber handle is adhesively fitted to the outer side of the top of the paddle. A support spring is fixedly connected between the middle of the paddle and the lower positioning seat.

[0014] Preferably, the bottom end of the paddle engages in the meshing structure of the rack.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In this invention, by controlling the upper positioning seat to move downward, it can cooperate with the lower positioning seat to clamp the optical fiber using two sets of flexible clamping components. As the upper positioning seat moves downward, the rubber block deforms and covers the surface of the optical fiber, increasing the contact area with the optical fiber and enhancing the friction between them. With the assistance of the adhesive layer, it is possible to achieve stable clamping and positioning of optical fibers of various types and diameters. The groove facilitates the deformation of the rubber block and can also serve as a heat dissipation channel, ensuring good heat dissipation at the optical fiber splice position.

[0017] When the upper positioning seat moves downward, the bottom of the paddle is subjected to downward squeezing force. At this time, the bottom of the paddle can rotate normally in the direction away from the rack. After the upper positioning seat is adjusted, the paddle can be reset by the support spring and its bottom can engage with the rack. Due to the limiting effect of the mounting groove, the paddle can limit the rack to prevent it from rebounding upward, thus ensuring the stability of the upper positioning seat position and the fiber optic connection.

[0026] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:

[0027] like Figure 1-5 As shown in the figure, the optical fiber core splice position fixer of this utility model includes a fixed base plate 1. Bolt mounting holes 2 are opened inside both the left and right ends of the fixed base plate 1. A lower positioning seat 3 is fixedly connected to the upper middle position of the fixed base plate 1. An upper positioning seat 4 is provided directly above the lower positioning seat 3. Positioning holes 5 are opened inside both the lower positioning seat 3 and the upper positioning seat 4. Flexible clamping components 6 for clamping optical cables are installed on the inner side of both the lower positioning seat 3 and the upper positioning seat 4. Two racks 7 are symmetrically fixed at the bottom of the left and right ends of the upper positioning seat 4. Two mounting grooves 8 are opened inside the left and right ends of the lower positioning seat 3. A positioning component 9 is provided inside the inner side of each mounting groove 8. The lower ends of the two racks 7 are respectively inserted into the two mounting grooves 8 and positioned by the positioning component 9.

[0028] As a preferred embodiment, based on the above structure, both the lower positioning seat 3 and the upper positioning seat 4 have a concave cross section, and the lower positioning seat 3 and the upper positioning seat 4 form a disassembly structure with the two sets of flexible clamping components 6 respectively.

[0029] In this embodiment, by controlling the upper positioning seat 4 to move vertically downward, the optical fiber can be stably clamped and positioned using two sets of flexible clamping components 6.

[0030] In a preferred embodiment, based on the above structure, the flexible clamping component 6 further includes a rubber block 61, a positioning element 62, a groove 63, an adhesive layer 64, and a release paper 65. The positioning element 62 is bonded to each of the four right angles on one side of the rubber block 61. The other side of the rubber block 61 has grooves 63 evenly spaced along the horizontal direction. The surface of the rubber block 61 with the grooves 63 is uniformly coated with the adhesive layer 64, and the surface of the adhesive layer 64 is covered with the release paper 65.

[0031] In this embodiment, as the upper positioning seat 4 moves downward, the rubber block 61 can deform and cover the surface of the optical fiber. At the same time, with the assistance of the adhesive layer 64, optical fibers of various types and diameters can be stably clamped and positioned. The groove 63 facilitates the deformation of the rubber block 61, and the groove 63 can also serve as a heat dissipation channel to ensure good heat dissipation at the optical fiber splice position.

[0032] As a preferred embodiment, based on the above structure, the number of positioning holes 5 opened inside the lower positioning seat 3 and the upper positioning seat 4 is equal to the number of positioning elements 62. The positioning elements 62 are made of elastic rubber, and the longitudinal section of the positioning elements 62 is umbrella-shaped and adapted to the positioning holes 5.

[0033] In this embodiment, the positioning element 62 and the positioning hole 5 facilitate the disassembly of the flexible clamping component 6 and both the lower positioning seat 3 and the upper positioning seat 4, making it convenient to replace the flexible clamping component 6 and enabling the fixture to be recycled and reused.

[0034] As a preferred embodiment, based on the above structure, the meshing structure of the two racks 7 is further provided on the side opposite to each other, and the bottom end of the rack 7 extends into the lower positioning seat 3 and is slidably connected to the lower positioning seat 3.

[0035] In this embodiment, the use of two racks 7 can ensure the vertical lifting and lowering adjustment of the upper positioning seat 4, and also facilitate the positioning of the upper positioning seat 4 by the positioning component 9.

[0036] As a preferred embodiment, based on the above structure, the positioning component 9 further includes a paddle 91, a handle 92 and a support spring 93. The paddle 91 is rotatably mounted on the inner side of the mounting groove 8. A rubber handle 92 is adhesively sleeved on the outer side of the top of the paddle 91. A support spring 93 is fixedly connected between the middle part of the paddle 91 and the lower positioning seat 3.

[0037] As a preferred embodiment, based on the above structure, the bottom end of the paddle 91 is further engaged in the meshing structure of the rack 7.

[0038] In this embodiment, the support spring 93 is used to provide support for the paddle 91, so that its bottom can be stably engaged with the meshing structure of the rack 7, thereby achieving stable positioning of the upper positioning seat 4.

[0039] The working principle of this utility model is as follows:

[0040] In use, firstly, the fixing base plate 1 can be positioned and installed in the designated position through the bolt mounting holes 2. Then, the optical fiber is placed on the rubber block 61 inside the lower positioning seat 3. Next, the upper positioning seat 4 is manually squeezed to move it vertically downwards, using methods such as... Figure 5 The two sets of flexible clamping components 6 shown in the figure facilitate clamping and positioning of optical fibers. When the upper positioning seat 4 moves down to clamp the optical fiber, the rubber block 61 will be compressed and deformed and cover the surface of the optical fiber, thereby increasing the contact area between it and the optical fiber and enhancing the friction between them. At the same time, with the assistance of the adhesive layer 64, it can achieve stable clamping and positioning of optical fibers of various types and diameters. Moreover, the groove 63 not only facilitates the deformation of the rubber block 61, but also serves as a heat dissipation channel to ensure good heat dissipation at the optical fiber splice position.

[0041] like Figure 5As shown, when the upper positioning seat 4 and the rack 7 move downward, the bottom of the lever 91 is subjected to downward squeezing force. Therefore, the bottom of the lever 91 can rotate away from the rack 7. After the upper positioning seat 4 is adjusted and stabilized to hold the optical fiber, the lever 91 can be reset by the support spring 93 and its bottom can re-engage with the meshing structure of the rack 7. Due to the limiting effect of the mounting groove 8, the lever 91 can only rotate in the set direction. Therefore, the lever 91 can play a limiting role in preventing the rack 7 from rebounding upward, ensuring the stability of the position of the upper positioning seat 4 and the optical fiber connection, and preventing the optical fiber connection from falling off. When it is necessary to release the positioning, the top of the lever 91 can be manually squeezed towards the rack 7.

[0042] It should be noted that the positioning element 62 and the positioning hole 5 allow the two sets of flexible clamping components 6 to be detached from the lower positioning seat 3 and the upper positioning seat 4, making the fixture easier to recycle and reuse, and thus more practical.

[0043] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
