[0002] Fiber optic active connectors are widely used products among optical passive devices, and the stable performance of the products is very important. In order to ensure the optical and mechanical reliability of fiber optic active connectors during use, a series of tests need to be carried out, among which the tensile test is an important part. The tensile test of fiber optic active connectors includes bending test, torsion test, tensile test and tail tensile test. These tensile tests require a certain load to be added to the optical cable of the fiber optic active connector. At present, the industry usually uses an 8-shaped winding capstan or a spiral winding cylinder to wind and fix the optical cable, and then add a load under the capstan or cylinder. The existing winding device has requirements for the number of turns of the optical cable, that is, the length of the optical cable, which is not suitable for shorter jumpers, and the winding operation is time-consuming and the test efficiency is low. Summary of the invention

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] According to the first aspect of the utility model, Figure 1As shown, a load device for tensile testing of an optical fiber active connector is provided, comprising:

[0025] Bottom plate 1, fixed top plate 2 and movable top plate 3;

[0026] The upper and lower parts of the bottom plate 1 are respectively provided with left and right through slide grooves 4, the fixed top plate 2 is fixedly connected to the right side of the bottom plate 1, the top and bottom ends of the fixed top plate 2 are fixedly connected to the right side of the slide groove 4, and the top and bottom ends of the movable top plate 3 are slidably connected to the left side of the slide groove 4;

[0027] The left end surface of the fixed top plate 2 and the right end surface of the movable top plate 3 are opposite to form an optical cable test channel 9, and the optical cable test channel 9 is curved;

[0028] A plurality of through holes 8 are respectively provided at the upper and lower parts of the bottom plate 1 .

[0029] In the utility model, a load device for tensile testing of an optical fiber active connector comprises a bottom plate 1, a fixed top plate 2 and a movable top plate 3; the upper and lower parts of the bottom plate 1 are respectively provided with left and right through slide grooves 4, the fixed top plate 2 is fixedly connected to the right side of the bottom plate 1, the top and bottom ends of the fixed top plate 2 are fixedly connected to the right side of the slide groove 4, and the top and bottom ends of the movable top plate 3 are slidably connected to the left side of the slide groove 4; the left end surface of the fixed top plate 2 and the right end surface of the movable top plate 3 are relatively formed into an optical cable test channel 9, and the optical cable of the optical fiber active connector to be tested can be placed in the optical cable test channel 9, and the movable top plate 3 can be placed in the optical cable test channel 9. The optical cable is approached until it contacts and forms a certain lateral pressure, thereby fixing the optical cable and the entire device together, and the weight of the device acts on the optical cable. At the same time, the clamping of the two top plates does not cause additional attenuation to the optical fiber of the optical cable; the optical cable test channel 9 is curved, which can make the optical cable under test fully contact with the left end face of the fixed top plate 2 and the right end face of the movable top plate 3 to prevent inaccurate test results caused by uneven force; the upper and lower parts of the bottom plate 1 are respectively provided with a plurality of through holes 8. Since it is often necessary to increase the load on the optical cable in the tensile test, this can be achieved by hooking weights in the through holes 8, and the plurality of through holes 8 can be used to adjust the size of the load.

[0030] The length of the optical cable fixedly clamped by the load device is only the length of the curved channel between the fixed top plate 2 and the movable top plate 3, which is much smaller than the length of the optical cable required for conventional capstan or drum winding, thereby expanding the application scenarios of the optical fiber active connector tension test and improving the flexibility and efficiency of the optical fiber active connector tension test.

[0031] Furthermore, the load device for the tension test of the optical fiber active connector also includes a rotary wrench 5;

[0032] Two limiting protrusions 6 are arranged on the left side of the bottom plate 1, and the right ends of the two limiting protrusions 6 are fixedly connected by a cross bar 7;

[0033] The rotary wrench 5 is connected to the cross bar 7 by threads, and the end of the rotary wrench 5 is fixedly connected to the middle part of the movable top plate 3.

[0034] In the tension test of the optical cable, the movable top plate 3 needs to be brought close to the optical cable until it contacts and forms a certain lateral pressure. If the movable top plate 3 is squeezed manually, it is difficult to ensure stable pressure and the efficiency is not high. Therefore, the movable top plate 3 can be brought close to the optical cable by rotating the wrench 5 until it contacts and forms a certain lateral pressure, so as to ensure the stability of the force of the optical cable in the test. Two limiting protrusions 6 are arranged on the left side of the bottom plate 1, which can prevent the movable top plate 3 slidably connected in the slide groove 4 from slipping out of the slide groove 4. The right ends of the two limiting protrusions 6 are fixedly connected by a cross bar 7, and the rotating wrench 5 is connected to the cross bar 7 by threads. The end of the rotating wrench 5 is fixedly connected to the middle part of the movable top plate 3. In this way, the cross bar 7, the rotating wrench 5 and the movable top plate 3 form a stable structure. The depth of the rotating wrench 5 can be adjusted by rotating the rotating wrench 5, and then the left and right positions of the movable top plate 3 can be adjusted, so that the movable top plate 3 can be continuously and stably close to the optical cable until it contacts and forms a certain lateral pressure, so as to ensure the smooth implementation and test accuracy of the tension test.

[0035] Furthermore, the end of the rotary wrench 5 is fixedly connected to the middle of the movable top plate 3 through threads.

[0036] The end of the rotary wrench 5 is fixedly connected to the middle of the movable top plate 3 by means of a thread, so that the contact depth and position of the movable top plate 3 and the rotary wrench 5 can be fine-tuned according to the test requirements or the manufacturing accuracy of the components, thereby preventing the rotary wrench 5 and the movable top plate 3 from being unreliably connected, thereby preventing the test from being unable to be smoothly implemented, and also improving the test accuracy to a certain extent.

[0037] Optionally, the minimum bending radius of the optical cable test channel 9 is not less than 20 mm.

[0038] The minimum bending radius of the optical cable test channel 9 is not less than 20 mm, ensuring that the optical cable test channel 9 is curved, so that the optical cable under test can fully contact the left end surface of the fixed top plate 2 and the right end surface of the movable top plate 3, preventing inaccurate test results caused by uneven force.

[0039] Furthermore, the rotary wrench 5 is used to adjust the left and right position of the movable top plate 3 .

[0040] The rotary wrench 5 is used to adjust the left and right position of the movable top plate 3. First, the left and right position of the movable top plate 3 can be adjusted more accurately to apply appropriate pressure to the optical cable. Second, it replaces manpower to ensure the stability of the applied pressure.

[0041] Furthermore, the limiting protrusion 6 is used to limit the position of the movable top plate 3 .

[0042] The limiting protrusion 6 is used to limit the position of the movable top plate 3, so as to prevent the movable top plate 3 from falling out of the slide groove 4 and affecting the efficiency of the tensile test.

[0043] In particular, the through hole 8 is used for hooking a weight.

[0044] The through hole 8 is used for hooking the weight, so that the weight can be hooked on the load device more easily, and the weight will not fall off in the middle of the test.

[0045] Preferably, three through holes 8 are respectively provided at the top and bottom ends of the bottom plate 1 .

[0046] The top and bottom of the bottom plate 1 are respectively provided with three through holes 8, and the tester can hang weights of different weights and combinations at the top and bottom as needed, thereby expanding the flexibility of the test.

[0047] Furthermore, the fixed top plate 2 is fixedly connected to the right side of the bottom plate 1 by means of fixing screws 10 .

[0048] The top plate 2 is fixedly connected to the right side of the bottom plate 1 by means of fixing screws 10. Fixing by means of fixing screws 10 is a common fixing connection method, which is convenient for disassembly, maintenance and replacement.

[0049] Optionally, there are multiple fixing screws 10, and preferably, there are two fixing screws 10.

[0050] There are multiple fixing screws 10, which can improve the firmness of fixing the top plate 2 to the bottom plate 1. Preferably, there are two fixing screws 10, which can be set at different positions of the bottom plate 1 as needed, thereby improving the manufacturing flexibility of the bottom plate 1.
