Description

Technical Field

[0001] This utility model belongs to the field of tensile testing equipment, and more specifically relates to a tensile testing fixture for ultrasonic welding strength of fiber optic adapters. Background Technology

[0002] Optical fiber, short for optical waveguide fiber, is a type of fiber made of glass or plastic that serves as a means of transmitting light. The main function of a fiber optic adapter is to connect two optical fibers or an optical fiber to an active device, ensuring the stability and efficiency of optical signals during transmission. By precisely aligning and securing the optical fibers, the adapter minimizes optical signal loss at the connection point, thereby guaranteeing the normal operation of the optical communication system.

[0003] Standard fiber optic adapters come in single, dual, and quad configurations. The manufacturing process for different adapter models requires ultrasonic welding between the fiber optic adapter and the adapter bracket. Tensile testing is necessary to assess the reliability of the welding.

[0004] The existing ultrasonic welding strength tensile test for fiber optic adapters has the following drawbacks:

[0005] 1. For example Figure 1 The diagram shows the structure of an existing ultrasonically welded fiber optic adapter and adapter bracket. Due to the lack of matching tooling fixtures and tensile testing devices for the existing fiber optic adapters, the tensile testing process is complicated, requiring different parts to be fixed separately on the tensile testing machine before testing.

[0006] 2. Low testing efficiency. Due to the reasons mentioned in point 1 above, frequent disassembly and manual fixing lead to low testing efficiency.

[0007] 3. Due to the specifications of fiber optic adapters, single-connect, dual-connect, and quad-connect adapters have different dimensions and installation locations, and there is a lack of a universal test fixture. Summary of the Invention

[0008] To address the aforementioned issues, this invention provides a simple, easy-to-install, convenient, and versatile ultrasonic welding strength and tensile testing fixture for fiber optic adapters.

[0009] According to one aspect of this utility model, a tensile strength testing fixture for ultrasonic welding of fiber optic adapters includes: a movable part, a first mounting support part, a second mounting support part, a driving part, a first fixing clamp, and a second fixing clamp. The first and second mounting supports are vertically arranged at the bottom of the movable part, and slide along the bottom of the movable part. The first fixing clamp is detachably mounted at the bottom of the first mounting support part, and the second fixing clamp is detachably mounted at the bottom of the second mounting support part. The first and second fixing clamps are symmetrically arranged about the vertical center line of the second mounting support part. The driving part connects the first and second mounting supports and drives them to move closer together. The driving part and the movable part bring the first and second mounting supports closer together, thereby fixing the fiber optic adapter to be tested. Separating the first and second mounting supports allows for quick and convenient tensile testing of the fiber optic adapter and replacement of the component under test. The detachable first and second fixing clamps facilitate the clamping of adapters of different specifications, making it widely applicable.

[0010] In some embodiments, the moving part includes: a body, a sliding groove disposed at the bottom of the body, and a slider that matches the sliding groove;

[0011] The sliding groove is a dovetail groove;

[0012] The slider is fixedly mounted on the top of the first mounting support and the second mounting support;

[0013] The slider is inserted into the sliding groove and can move within it. By moving the slider within the sliding groove, the first and second fixed clamps move closer together, ultimately clamping and securing the adapter.

[0014] In some embodiments, the first mounting support includes a first support arm, a first mounting hole, a second mounting hole, and a third mounting hole, with the first mounting hole, second mounting hole, and third mounting hole arranged sequentially from top to bottom on the first support arm. The first and second mounting holes facilitate the installation of the first drive assembly and the second drive assembly, while the third mounting hole facilitates the detachable installation of the first fixing clamp.

[0015] In some embodiments, the second mounting support includes a second support arm, a fourth mounting hole, a fifth mounting hole, and a sixth mounting hole, wherein the fourth mounting hole, the fifth mounting hole, and the sixth mounting hole are sequentially arranged from top to bottom on the second support arm. The fourth and fifth mounting holes facilitate the installation of the first and second drive components, while the sixth mounting hole facilitates the detachable installation of the second fixing clamp.

[0016] In some embodiments, the drive unit includes: a first drive component and a second drive component;

[0017] The first drive assembly passes through the first mounting hole and the fourth mounting hole to drive the first support arm and the second support arm to move closer to each other;

[0018] The second drive assembly passes through the second and fifth mounting holes to drive the first and second support arms closer together. By simultaneously driving the first and second support arms closer together using both drive assemblies, the clamping force is more even, and the movement is smoother.

[0019] In some embodiments, the first drive assembly includes a sliding rod, an end cap, a first spring, a second spring, and a nut. The sliding rod passes through a first mounting hole and a fourth mounting hole. One end of the sliding rod has an end cap, and the other end of the sliding rod is connected to the nut via an external thread. The first spring is sleeved on the sliding rod and is defined by the end cap and a first support arm. The second spring is sleeved on the sliding rod and is defined by the nut and a second support arm. The first and second springs provide a driving force for the first and second support arms to move closer together. The rotation of the nut allows for adjustment of the spring forces of the first and second springs to adapt to different clamping needs.

[0020] In some implementations, the structure of the first driving component is the same as that of the second driving component.

[0021] In some embodiments, a bolt passes through a third mounting hole and connects to a first fixing clamp, detachably fixing the first fixing clamp to the bottom of the first support arm. Similarly, a bolt passes through a sixth mounting hole and connects to a second fixing clamp, detachably fixing the second fixing clamp to the bottom of the second support arm. The detachable installation of the first and second fixing clamps facilitates the clamping of adapters of different specifications, making it widely applicable.

[0022] In some embodiments, a fixing hole is provided in the center of the top of the main body. The fixing hole facilitates connection with a tensile testing machine.

[0023] Compared with the existing technology, this utility model has the advantages of simple structure, convenient installation, convenient testing and good practicality. This invention uses a drive unit and a moving unit to bring the first and second mounting supports closer together, thereby fixing the fiber optic adapter to be inspected. Separating the first and second mounting supports allows for quick and convenient installation tensile testing of the fiber optic adapter and replacement of the component under test. The detachable first and second fixing clamps facilitate clamping adapters of different specifications, making it widely applicable. The sliding block moves within a sliding groove to bring the first and second fixing clamps closer together, ultimately clamping and fixing the adapter. The first and second mounting holes facilitate the installation of the first and second drive components, while the third mounting hole facilitates the detachable installation of the first fixing clamp. The fourth and fifth mounting holes facilitate the installation of the first and second drive components, and the sixth mounting hole facilitates the detachable installation of the second fixing clamp. The first and second drive components simultaneously drive the first and second support arms closer together, resulting in more even clamping force and smoother movement. The first and second springs provide the driving force for the first and second support arms to move closer together, and the rotation of the nut allows for adjustment of the spring force of the first and second springs to adapt to different clamping needs. The fixing holes facilitate connection to a tensile testing machine. Attached Figure Description

[0029] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0030] In the description of this invention, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the terms according to the specific circumstances.

[0031] like Figure 1 As shown, in the existing technology, the welding strength of the fiber optic adapter and adapter bracket after ultrasonic welding needs to be tested. The existing technology directly connects the fiber optic adapter and bracket to the upper and lower parts of the tensile testing machine for testing. This connection process with the adapter is cumbersome and inefficient.

[0032] like Figure 2 As shown, the ultrasonic welding strength tensile testing fixture for fiber optic adapters of this utility model includes: a movable part 1, a first mounting support part 2, a second mounting support part 3, a driving part 4, a first fixing clamp 5, and a second fixing clamp 6. The first mounting support part 2 and the second mounting support part 3 are vertically arranged at the bottom of the movable part 1. The first mounting support part 2 and the second mounting support part 3 slide at the bottom of the movable part 1. The first fixing clamp 5 is detachably installed at the bottom of the first mounting support part 2, and the second fixing clamp 6 is detachably installed at the bottom of the second mounting support part 3. The first fixing clamp 5 and the second fixing clamp 6 are symmetrically arranged about the vertical center line of the second mounting support part 3 of the first mounting support part 2. The driving part 4 connects the first mounting support part 2 and the second mounting support part 3 and drives the first mounting support part 2 and the second mounting support part 3 to move closer to each other. The first mounting support 2 and the second mounting support 3 are brought closer together by the drive unit 4 and the moving unit 1, thereby fixing the fiber optic adapter to be inspected. The fiber optic adapter can be quickly and conveniently replaced by separating the first mounting support 2 and the second mounting support 3 to perform installation tension test. At the same time, the detachable first fixing clamp 5 and the second fixing clamp 6 are used to fix and clamp adapters of different specifications, which has a wide range of applications.

[0033] like Figure 3 As shown, the moving part 1 includes: a body 11, a sliding groove 12 disposed at the bottom of the body 11, and a slider 13 that matches the sliding groove 12;

[0034] Sliding groove 12 is a dovetail groove;

[0035] The slider 13 is fixedly mounted on the top of the first mounting support 2 and the second mounting support 3;

[0036] The slider 13 is inserted into the sliding groove 12 and can move within the sliding groove 12. By moving the slider 13 within the sliding groove 12, the first fixed clamp 5 and the second fixed clamp 6 move closer to each other, ultimately clamping and fixing the adapter.

[0037] The main body 11 has a fixing hole 14 in the middle of its top. The fixing hole 14 facilitates connection with a tensile testing machine. In normal use, this utility model is hung above the tensile testing machine through the fixing hole 14. When testing is required, the adapter is clamped and fixed with the first fixing clamp 5 and the second fixing clamp 6, and the bottom of the adapter is connected to the bottom of the tensile testing machine to perform the test.

[0038] The first mounting support 2 includes a first support arm 21, a first mounting hole 22, a second mounting hole 23, and a third mounting hole 24. The first support arm 21 is provided with the first mounting hole 22, the second mounting hole 23, and the third mounting hole 24 from top to bottom. The first mounting hole 22 and the second mounting hole 23 facilitate the installation of the first drive assembly 41 and the second drive assembly 42, while the third mounting hole 24 facilitates the detachable installation of the first fixing clamp 5.

[0039] The second mounting support 3 includes a second support arm 31, a fourth mounting hole 32, a fifth mounting hole 33, and a sixth mounting hole 34. The fourth mounting hole 32, the fifth mounting hole 33, and the sixth mounting hole 34 are arranged sequentially from top to bottom on the second support arm 31. The fourth mounting hole 32 and the fifth mounting hole 33 facilitate the installation of the first drive assembly 41 and the second drive assembly 42, while the sixth mounting hole 34 facilitates the detachable installation of the second fixing clamp 6.

[0040] like Figure 4 As shown, the drive unit 4 includes: a first drive component 41 and a second drive component 42;

[0041] The first drive assembly 41 passes through the first mounting hole 22 and the fourth mounting hole 32 to drive the first support arm 21 and the second support arm 31 to move closer to each other;

[0042] The second drive assembly 42 passes through the second mounting hole 23 and the fifth mounting hole 33 to drive the first support arm 21 and the second support arm 31 closer together. By simultaneously driving the first support arm 21 and the second support arm 31 closer together through the first drive assembly 41 and the second drive assembly 42, the clamping force is more uniform and the movement is smoother.

[0043] The first drive assembly 41 includes a sliding rod 411, an end cap 412, a first spring 413, a second spring 414, and a nut 415. The sliding rod 411 passes through a first mounting hole 22 and a fourth mounting hole 32. One end of the sliding rod 411 is provided with the end cap 412, and the other end of the sliding rod 411 is connected to the nut 415 via an external thread. The first spring 413 is sleeved on the sliding rod 411 and is defined by the end cap 412 and the first support arm 21. The second spring 414 is sleeved on the sliding rod 411 and is defined by the nut 415 and the second support arm 31. The first spring 413 and the second spring 414 provide a driving force for the first support arm 21 and the second support arm 31 to move closer to each other. The rotation of the nut 415 allows for adjustment of the elasticity of the first spring 413 and the second spring 414 to adapt to different clamping needs.

[0044] The structure of the first drive component 41 is the same as that of the second drive component 42.

[0045] like Figure 5 As shown, in the specific implementation process, the first mounting support 2 and the second mounting support 3 are separated to both sides, the adapter to be tested is placed between the first fixing clamp 5 and the second fixing clamp 6, the first mounting support 2 and the second mounting support 3 are released, the first spring 413 pushes the first support arm 21 towards the middle adapter, and the first fixing clamp 5 abuts against the adapter. At the same time, the second spring 414 pushes the first support arm 21 towards the middle adapter, and the second fixing clamp 6 abuts against the adapter. The adapter is clamped and fixed by the first fixing clamp 5 and the second fixing clamp 6.

[0046] It should be noted that in order to maintain the clamping force, the first spring 413 and the second spring 414 should be kept compressed after the adapter is connected in order to provide sufficient thrust to secure the adapter.

[0047] A bolt passes through the third mounting hole 24 and connects to the first fixing clamp 5, detachably fixing the first fixing clamp 5 to the bottom of the first support arm 21. A bolt passes through the sixth mounting hole 34 and connects to the second fixing clamp 6, detachably fixing the second fixing clamp 6 to the bottom of the second support arm 31. The detachable installation of the first fixing clamp 5 and the second fixing clamp 6 facilitates the clamping of adapters of different specifications, making it widely applicable.

[0048] The above descriptions are merely some embodiments of this utility model. It should be noted that those skilled in the art can make other modifications and improvements without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
