Subsequently, the controller controls the atomizer to operate, causing it to spray atomized water vapor to increase the humidity of the environment.

Description

Technical Field

[0001] This utility model relates to the technical field of tensile testing equipment, specifically to a tensile testing device for fiber optic connectors. Background Technology

[0002] Fiber optic connector tensile testing equipment is a specialized instrument used to evaluate the mechanical properties and structural reliability of fiber optic connectors under tensile force. By applying a controllable traction force, it simulates the stress state of fiber optic connectors under actual installation, maintenance, or accidental stress scenarios, and detects their deformation, displacement, fracture threshold, and residual performance under specified loads. However, existing fiber optic connector tensile testing equipment can only apply tension to the fiber at a fixed position, resulting in relatively simple results that cannot reflect the tensile strength of the fiber optic connector under different operating conditions, leading to poor practicality. At the same time, fiber optic connectors lack the ability to simulate humidity environments, making it difficult to truly reflect the performance degradation of the connector under actual operating conditions, which can lead to changes in tensile performance.

[0003] Therefore, a tensile testing device for fiber optic connectors is needed to improve the above-mentioned problems. Utility Model Content

[0004] To address the problem that tensile testing equipment can only apply tension to the fiber optic cable at a fixed position when testing fiber optic connectors, resulting in limited and unreliable results that cannot reflect the tensile strength of the fiber optic connector under different operating conditions, this invention provides a tensile testing device for fiber optic connectors to solve the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A tensile testing device for fiber optic connectors includes a mounting base. A controller is mounted on the outer wall of the mounting base via a support column. Tensile components are mounted on the outer wall of the mounting base, wherein two sets of tensile components are provided and are respectively located on opposite outer walls of the mounting base. A testing component is mounted on one side of the tensile components and on the outer wall of the mounting base. Mounting brackets are symmetrically arranged on the other side of the tensile components and on the outer wall of the mounting base. Fiber optic fixing seats are mounted on the outer wall of the mounting brackets.

[0006] As a preferred embodiment of this utility model, the tensile assembly includes a fixed base and a tensile testing machine. The fixed base is installed on the inner wall of the mounting base, and a sliding base is installed on the base surface of the fixed base. An mounting frame is installed on the outer wall opposite to the sliding base, and a transmission wheel is rotatably connected to the inner wall opposite to the mounting frame. The transmission wheels are connected to each other via a transmission belt.

[0007] As a preferred embodiment of this utility model, one end of the transmission wheel passes through the mounting frame and extends to the outer wall of the mounting frame where a drive motor is mounted. A mounting plate is slidably connected to the outer wall of the sliding base, and a transmission belt is connected to the bottom outer wall of the mounting plate via a connecting block.

[0008] As a preferred embodiment of this utility model, a fixing column is installed on the outer wall of the mounting plate, wherein two sets of fixing columns are provided and are respectively located on the opposite outer walls of the mounting plate, and a movable base is slidably connected to the outer wall of the fixing column. A fixing plate is installed on the top outer wall of the movable base, wherein two sets of fixing plates are provided and are respectively located on the outer wall of the movable base.

[0009] As a preferred embodiment of this utility model, a bearing is installed on the outer wall of the fixed plate, a limiting roller is rotatably connected to the inner wall of the bearing, and a tensile testing machine is installed on the bottom outer wall of the movable base, wherein one end of the tensile testing machine is connected to the base surface of the fixed plate.

[0010] As a preferred embodiment of this utility model, the test component includes a fixed bracket, which is installed on the outer wall of the mounting base. A positioning plate is installed on the top outer wall of the fixed bracket, and positioning rods are symmetrically arranged on the outer wall of the positioning plate.

[0011] As a preferred embodiment of this utility model, a enclosure shell is slidably connected to the outer wall of the positioning rod, wherein the enclosure shell and the fixed bracket are connected by a sliding connection, and an atomizer is installed on the inner wall of the enclosure shell, wherein the atomizer is located in the inner cavity of the fixed bracket.

[0012] As a preferred embodiment of this utility model, an electrically controlled cylinder is installed directly below the positioning plate and on the inner wall of the fixed bracket. One end of the electrically controlled cylinder is equipped with a guide rod, wherein one end of the guide rod passes through the positioning plate and extends to the outer wall of the positioning plate to connect to the enclosure shell. The controller is connected to the drive motor, tensile testing machine, atomizer and electrically controlled cylinder through wires, and the connection method is electrical connection.

[0013] Compared with existing technologies, this invention enables the adjustment of the tensile testing machine's position by setting a tensile component in the fiber optic connector tensile testing equipment, thereby allowing tensile testing of the optical fiber from different positions. A drive motor drives the transmission wheel and transmission belt in tandem. The transmission belt displacement pushes the mounting plate laterally along the sliding base via a connecting block. A dual tensile component pulls the optical fibers from both sides of the connector. Positioning is achieved through a linkage mechanism of fixed columns, fixed plates, bearings, and limiting rollers. After the limiting rollers move to the preset position, the controller controls the tensile testing machine to perform the tensile test. The tensile component can drive the tensile testing machine to move laterally, adjusting to different positions to apply tensile force to the optical fiber. This solves the problem that existing fiber optic connector tensile testing equipment can only apply tensile force to the optical fiber at a fixed position, resulting in limited and unreliable results that cannot reflect the tensile force resisted by the fiber optic connector under different operating conditions, thus lacking practicality.

[0014] This invention increases the humidity of the environment by setting up a test component in the fiber optic connector tensile testing equipment. By activating the controller to operate the electrically controlled cylinder, one end of the cylinder applies a downward pulling force to the enclosure housing via a guide rod. This causes the enclosure housing to move downward on the outer wall of the positioning rod, thus enclosing the fiber optic connector. Subsequently, the controller controls the atomizer to spray atomized water vapor to increase the humidity of the environment. Then, the tensile component performs a tensile test on the fiber optic cable, allowing the fiber optic connector to undergo a tensile test in a humid environment. This solves the problem that fiber optic connectors lack the ability to simulate humidity environments, making it difficult to accurately reflect the performance degradation of connectors under actual working conditions, which leads to changes in tensile performance.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

Two sets of tensile components 4 are provided and are located on opposite outer walls of the mounting base 1. A test component 5 is mounted on one side of the tensile component 4 and on the outer wall of the mounting base 1. A mounting bracket 6 is symmetrically arranged on the other side of the tensile component 4 and on the outer wall of the mounting base 1. A fiber optic fixing seat 7 is mounted on the outer wall of the mounting bracket 6.

[0019] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 and Figure 4The tensile assembly 4 includes a fixed base 401 and a tensile testing machine 402. The fixed base 401 is mounted on the inner wall of the mounting base 1. A sliding base 403 is mounted on the base surface of the fixed base 401. A mounting frame 404 is mounted on the opposite outer wall of the sliding base 403. A transmission wheel 405 is rotatably connected to the opposite inner wall of the mounting frame 404, and the transmission wheels 405 are connected to each other by a transmission belt 406. One end of the transmission wheel 405 passes through the mounting frame 404 and extends to the outer wall of the mounting frame 404 where a drive motor 407 is mounted. A mounting plate 408 is slidably connected to the outer wall of the sliding base 403. A connecting block 409 connects the bottom outer wall of the mounting plate 408 to the mounting plate 403. A drive belt 406 is connected to the outer wall of the mounting plate 408, and a fixed column 410 is installed on the outer wall of the mounting plate 408. Two sets of fixed columns 410 are provided and are located on opposite outer walls of the mounting plate 408. A movable base 411 is slidably connected to the outer wall of the fixed column 410. A fixed plate 412 is installed on the top outer wall of the movable base 411. Two sets of fixed plates 412 are provided and are located on the outer wall of the movable base 411. A bearing 413 is installed on the outer wall of the fixed plate 412. A limit roller 414 is rotatably connected to the inner wall of the bearing 413. A tensile testing machine 402 is installed on the bottom outer wall of the movable base 411, and one end of the tensile testing machine 402 is connected to the base surface of the fixed plate 412.

[0020] Based on the above structural features and connection relationship, the drive shaft of the drive motor 407 drives the transmission wheel 405 to rotate, thereby causing the transmission wheel 405 to apply force to the transmission belt 406. When the transmission belt 406 is displaced by the force, the transmission belt 406 will apply a lateral displacement force to the mounting plate 408 through the connecting block 409, thereby causing the mounting plate 408 to move laterally on the outer wall of the sliding base 403. In this embodiment, specific references Figure 1 , Figure 2 , Figure 4 and Figure 5 The test component 5 includes a fixed bracket 501, which is installed on the outer wall of the mounting base 1. A positioning plate 502 is installed on the top outer wall of the fixed bracket 501. Positioning rods 503 are symmetrically arranged on the outer wall of the positioning plate 502. A enclosure shell 504 is slidably connected to the outer wall of the positioning rods 503. The enclosure shell 504 and the fixed bracket 501 are connected by a sliding connection. An atomizer 505 is installed on the inner wall of the enclosure shell 504. The atomizer 505 is located in the inner cavity of the fixed bracket 501. An electric cylinder 506 is installed directly below the positioning plate 502 and on the inner wall of the fixed bracket 501. A guide rod 507 is installed at one end of the electric cylinder 506. One end of the guide rod 507 passes through the positioning plate 502 and extends to the outer wall of the positioning plate 502 to connect with the enclosure shell 504. The controller 3 is electrically connected to the drive motor 407, tensile testing machine 402, atomizer 505 and electric cylinder 506 via wires, thereby energizing the device and enabling the controller 3 to control the operation of the drive motor 407, tensile testing machine 402, atomizer 505 and electric cylinder 506.

[0021] When the fiber optic connector tensile testing equipment of this scheme is working, the two ends of the fiber are fixed on the inner wall of the fiber fixing seat 7, and the two ends of the fiber are respectively clamped on the inner wall of the limiting roller 414, so that the limiting roller 414 limits the fiber, while the fiber optic connector is located in the inner cavity of the fixing bracket 501. By turning on the switch of controller 3, controller 3 controls drive motor 407 to run. When drive motor 407 runs, drive shaft of drive motor 407 drives transmission wheel 405 to run, which in turn causes transmission wheel 405 to apply force to transmission belt 406. When transmission belt 406 is displaced by force, transmission belt 406 will apply lateral displacement force to mounting plate 408 through connecting block 409, which will cause mounting plate 408 to move laterally on the outer wall of sliding base 403. By setting two sets of tension components 4, the two sets of tension components 4 will stretch the optical fibers on both sides of the optical fiber connector respectively, so that the mounting plate 408 drives the fixing plate 412 to move via the fixing post 410, and then the fixing plate 412 drives the limiting roller 414 to move via the bearing 413. When the limiting roller 414 moves to the appropriate position, the controller 3 controls the tensile testing machine 402 to operate, and then the tensile testing machine 402 applies tension to the optical fiber. The tension components 4 can drive the tensile testing machine 402 to move laterally to adjust to different positions to apply tension to the optical fiber, thereby solving the problem that the existing optical fiber connector tensile testing equipment can only apply tension to the optical fiber at a fixed position, and the results obtained are relatively simple and cannot reflect the tensile force that the optical fiber connector can withstand under different working conditions, resulting in poor practicality. By activating controller 3, the controller 3 controls the operation of the electronically controlled cylinder 506, which in turn applies a downward pulling force to the enclosure housing 504 via the guide rod 507. This causes the enclosure housing 504 to move downward on the outer wall of the positioning rod 503, thus moving it to one side of the fiber optic connector to form a barrier. Subsequently, controller 3 controls the atomizer 505 to operate, causing it to spray atomized water vapor to increase the humidity of the environment. Then, the tensile component 4 performs a tensile test on the optical fiber, allowing the fiber optic connector to undergo a tensile test in a humid environment. This solves the problem that the fiber optic connector lacks the ability to simulate humidity environments, making it difficult to accurately reflect the performance degradation of the connector under actual working conditions, which can lead to changes in tensile performance.
