Description

Technical Field

[0001] This utility model relates to the field of optical fiber technology, and more specifically, to an optical fiber branch connector. Background Technology

[0002] Optical fiber is a device that transmits signals using the principle of total internal reflection of light, with a core, cladding, and coating as its basic structure. It can be divided into single-mode and multi-mode according to the transmission mode, and into step and graded refractive index according to the refractive index distribution. Due to its advantages such as large transmission capacity and low loss, it has become the core medium of modern communication. Optical fiber branch connectors are passive devices used for optical signal distribution or aggregation.

[0003] Currently, existing fiber optic branch connectors employ a structural design: the fiber branch position is built into the connector, and then the main fiber and branch fiber are respectively installed into the connector. The main and branch fibers are then secured by the merging of the connector housing. To prevent the branch fiber from shifting inside the connector, existing designs incorporate barbs at the contact points between the connector and the branch fiber. When the branch fiber is pressed into the connector, the barbs function to position it.

[0004] However, branched optical fibers are inevitably subjected to pulling during actual use. Although barbs can prevent the branched optical fibers from shifting, once pulling occurs, the barbs will scratch the outer protective layer of the branched optical fiber, causing the branched optical fiber body to be exposed, which in turn affects the normal use of the optical fiber. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fiber optic branch connector.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fiber optic branch connector, comprising a main body assembly and a branch assembly and a positioning assembly disposed inside the main body assembly.

[0007] The main body component includes an upper shell and a lower shell.

[0008] The branching assembly includes a main optical fiber and a branch optical fiber, which are connected together. The upper and lower housings each have a groove on their opposite sides. The connection between the main optical fiber and the branch optical fiber is located inside the groove. A trapezoidal branch plate is installed inside each of the two grooves.

[0009] The positioning component includes two movable blocks. A groove is provided on the top of the trapezoidal branch plate corresponding to the lower housing. Both movable blocks are slidably connected inside the groove. Rubber blocks are connected to the opposite sides of the two movable blocks. The rubber blocks are in contact with the outer wall of the corresponding branch optical fiber.

[0010] The present invention is further configured such that: the main body component includes two insert plates symmetrically connected to the bottom of the upper housing, and two slots symmetrically opened on the top of the lower housing, the two insert plates being arranged corresponding to the two slots, and the insert plates being inserted into the interior of the corresponding slots.

[0011] The present invention is further configured such that: a wedge-shaped block is connected to one side of each of the two insert plates that are opposite to each other, and a slot is provided on the inner sidewall of each slot, with the wedge-shaped block and the slot corresponding to each other.

[0012] By adopting the above technical solution, when the upper shell and the lower shell are connected, the insert plate is inserted into the corresponding slot. At the same time, the insert plate drives the wedge block to be inserted into the slot. In this state, the inclined surface of the bottom of the wedge block is pressed against the side wall of the slot, and the insert plate is bent by the pressure. When the wedge block moves to the position of the slot, the elasticity of the insert plate pushes the wedge block to move into the slot, so that the wedge block is stuck in the slot, thereby completing the splicing and assembly of the upper shell and the lower shell.

[0013] The present invention is further configured such that: the branch assembly includes a first adapter slot on one side of the upper housing and the lower housing, the two first adapter slots are respectively provided corresponding to the outer wall of the main optical fiber, and two second adapter slots are symmetrically provided at the bottom of the upper housing and the top of the lower housing, the two opposite second adapter slots are spliced ​​together and are respectively provided corresponding to one of the branch optical fibers.

[0014] By adopting the above technical solution, the connection point between the main optical fiber and the branch optical fiber is located inside the groove. This provides space to accommodate the fiber connection, offering load-bearing capacity and initial protection to prevent damage from external impacts. Trapezoidal branch plates are installed inside both grooves to separate the branch optical fibers. This prevents the branch optical fibers from tangling and squeezing each other, ensuring the independence of each branch optical fiber, reducing signal interference, and facilitating the sorting and management of the branch optical fibers.

[0015] The present invention is further configured such that: a guide groove is provided on one side wall of the slide groove; guide blocks are connected to the side walls of the two moving blocks on the same side; the guide blocks are adapted to the guide groove; a first wedge-shaped surface is provided on the opposite side of the two moving blocks; an insert is connected to the bottom of the trapezoidal branch plate corresponding to the upper shell; a second wedge-shaped surface is provided on both sides of the insert; and the second wedge-shaped surface is adapted to the first wedge-shaped surface.

[0016] The present invention is further configured such that: a limiting groove is formed inside the sliding groove and on the side away from the guide groove; a limiting rod is connected inside the limiting groove; two limiting blocks are slidably connected to the outer wall of the limiting rod; the two limiting blocks are correspondingly arranged with two moving blocks; and the limiting blocks are connected to the corresponding moving blocks.

[0017] The present invention is further configured such that: a spring is connected to one side of each of the two limiting blocks that are opposite to each other; the side of the spring that is away from the limiting block is connected to the side wall of the limiting groove; and both springs are sleeved on the outer wall of the limiting rod.

[0018] By adopting the above technical solution, when the upper and lower shells are spliced, the insert block is used to squeeze the moving block so that the rubber block fits against the branch optical fiber. In this way, the softness of the rubber block can buffer the squeezing force and avoid the barbs from scratching the protective layer, thus protecting the branch optical fiber and ensuring its normal use. By setting a limiting component, the wedge-shaped surfaces of the insert block and the moving block are used to achieve positioning. Moreover, the spring force is used to reset the moving block for easy disassembly. Positioning and disassembly can be completed without barbs, achieving convenient operation and preventing secondary damage to the branch optical fiber.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] (1) By setting up a moving block, a rubber block and a plug, when the upper shell and the lower shell are spliced, the plug is used to squeeze the moving block so that the rubber block fits the branch optical fiber. In this way, the softness of the rubber block can buffer the squeezing force and avoid using barbs to scratch the protective layer, thus achieving the effect of protecting the branch optical fiber and ensuring its normal use.

[0021] (2) By setting a limiting component, positioning is achieved by the wedge-shaped surface of the insert block and the moving block. Moreover, the spring force is used to reset the moving block for easy disassembly. Positioning and disassembly can be completed without barbs, achieving the effect of convenient operation and preventing secondary damage to the branch optical fiber. Attached Figure Description

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0033] Please see Figures 1-6 The present invention provides the following technical solution:

[0034] Example 1, see Figures 1-4 A fiber optic branch connector includes a main body assembly 1, which comprises an upper housing 11 and a lower housing 12. The upper housing 11 and lower housing 12 serve as the body of the branch connector. Two insert plates 13 are symmetrically connected to the bottom of the upper housing 11. Wedge blocks 14 are connected to opposite sides of each insert plate 13. Two slots 15 are symmetrically formed on the top of the lower housing 12. The two insert plates 13 are correspondingly positioned within the two slots 15. Each insert plate 13 is inserted into the corresponding slot 15. A slot 16 is formed on the inner wall of each slot 15. The wedge blocks 14... 4. Corresponding to the slot 16, when the upper housing 11 and the lower housing 12 are connected, the insert plate 13 is inserted into the corresponding slot 15. At the same time, the insert plate 13 drives the wedge block 14 to be inserted into the slot 15. In this state, the inclined surface of the bottom of the wedge block 14 is pressed against the side wall of the slot 15, and the insert plate 13 is bent by the pressure. When the wedge block 14 moves to the position of the slot 16, the elasticity of the insert plate 13 pushes the wedge block 14 to move into the slot 16, so that the wedge block 14 is stuck in the slot 16, thereby completing the splicing and assembly of the upper housing 11 and the lower housing 12.

[0035] A branch assembly 2 and a positioning assembly 3 are provided between the upper housing 11 and the lower housing 12. The branch assembly 2 includes a main optical fiber 22 and a branch optical fiber 23. The main optical fiber 22 and the branch optical fiber 23 are connected. The connection between the main optical fiber 22 and the branch optical fiber 23 is protected by the main body assembly 1. A groove 21 is provided on the opposite side of the upper housing 11 and the lower housing 12. The connection between the main optical fiber 22 and the branch optical fiber 23 is located inside the groove 21. The groove 21 is used to support the connection position of the main optical fiber 22 and the branch optical fiber 23.

[0036] Both grooves 21 are fitted with trapezoidal branch plates 26, which are used to separate the branch optical fibers 23. The branch assembly 2 also includes a first adapter groove 24 on the opposite side of the upper housing 11 and the lower housing 12. The two first adapter grooves 24 are respectively set to correspond to the outer wall of the main optical fiber 22. The bottom of the upper housing 11 and the top of the lower housing 12 are symmetrically set with two second adapter grooves 25. The two opposite second adapter grooves 25 are spliced ​​together and are set to correspond to one of the branch optical fibers 23. When the upper housing 11 and the lower housing 12 are spliced ​​together, the two second adapter grooves 25 are spliced ​​together to support and hold the main optical fiber 22, and the two corresponding first adapter grooves 24 are spliced ​​together to support the branch optical fiber 23. In this state, the main optical fiber 22 and the branch optical fiber 23 are protected by the cooperation of the upper housing 11 and the lower housing 12. At the same time, the main optical fiber 22 can be connected to the branch optical fiber 23 through the branch connector.

[0037] The positioning component 3 includes two movable blocks 37. The top of the trapezoidal branch plate 26 corresponding to the lower housing 12 is provided with a sliding groove 31. Both movable blocks 37 are slidably connected inside the sliding groove 31. Rubber blocks 301 are respectively connected to the opposite sides of the two movable blocks 37. The rubber blocks 301 are attached to the outer wall of the corresponding branch optical fiber 23. The movable blocks 37 are used to slide inside the sliding groove 31. When the two movable blocks 37 are separated from each other, the rubber blocks 301 on the side wall of the movable blocks 37 are attached to the outer wall of the branch optical fiber 23, thereby positioning the branch optical fiber 23.

[0038] One side wall of the slide groove 31 is provided with a guide groove 32. The side walls of the two moving blocks 37 are connected with guide blocks 33 on the same side. The guide blocks 33 are adapted to the guide groove 32. During the sliding process, the moving blocks 37 drive the guide blocks 33 to slide inside the guide groove 32 at the same time, thereby providing auxiliary guidance for the movement direction of the moving blocks 37. The opposite side of the two moving blocks 37 is provided with a first wedge surface 39. The bottom of the trapezoidal branch plate 26 corresponding to the upper shell 11 is connected with an insert block 302. The two sides of the insert block 302 are provided with a second wedge surface 303, which is adapted to the first wedge surface 39.

[0039] When the upper housing 11 and the lower housing 12 are spliced, the upper housing 11 drives the corresponding insert block 302 to press the two moving blocks 37, that is, the insert block 302 moves to the position between the two moving blocks 37. Then, the second wedge surface 303 on the side wall of the insert block 302 slides and presses on the first wedge surface 39. The two moving blocks 37 are separated by the pressure of the insert block 302 at the same time. During the separation process, the moving block 37 drives the rubber block 301 to fit with the branch optical fiber 23, thereby positioning the branch optical fiber 23.

[0040] A limiting groove 34 is formed inside the slide groove 31 on the side away from the guide groove 32. A limiting rod 35 is connected inside the limiting groove 34. Two limiting blocks 36 are slidably connected to the outer wall of the limiting rod 35. The two limiting blocks 36 are correspondingly set with two moving blocks 37. The limiting blocks 36 are connected to the corresponding moving blocks 37. A spring 38 is connected to the opposite side of the two limiting blocks 36. The side of the spring 38 away from the limiting block 36 is connected to the side wall of the limiting groove 34. Both springs 38 are sleeved on the outer wall of the limiting rod 35. When the spring 38 is in a free state, the corresponding limiting block 36 remains stationary, that is, there is a gap between the two limiting blocks 36. At the same time, the two moving blocks 37... There is also a gap between 7. When the insert block 302 presses the moving block 37, the moving block 37 drives the corresponding limiting block 36 to move synchronously. The limiting block 36 slides on the outer wall of the limiting rod 35 and presses the spring 38. Subsequently, during the separation process, the two moving blocks 37 drive the rubber block 301 to adhere to the branch optical fiber 23, thereby positioning the branch optical fiber 23. Due to the splicing of the upper shell 11 and the lower shell 12, the insert block 302 maintains the pressing state of the two moving blocks 37, thereby keeping the moving blocks 37 in the pressing state of the branch optical fiber 23. This ensures that the outer protective layer of the branch optical fiber 23 is not damaged, while also preventing the branch optical fiber 23 from shifting.

[0041] Conversely, when the upper housing 11 and the lower housing 12 are separated, the insert block 302 simultaneously releases the squeezing state of the moving block 37. The moving block 37 is moved away from the branch optical fiber 23 by the elastic force of the spring 38, making it convenient for staff to pick up the branch optical fiber 23 and preventing the branch optical fiber 23 from being inconvenient to remove due to its barbs and causing secondary damage.

[0042] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
