When testing an optical cable with a small outer diameter of a reinforcing element, the optical cable surface can be prevented from slipping with a clamp that applies tension, thereby ensuring stable and accurate testing and having large adhesion of the reinforcing element.

[0005] The technical solution of the present invention is as follows: the butterfly optical cable has a reinforcement member arranged parallel to its axial direction, and is characterized in that the optical cable adhesion detection device comprises a tensile machine 1, a force-applying end clamp 2 and a fixed end clamp 3, the tensile machine 1 and the fixed end clamp 2 are fixedly connected to a frame 4, the force-applying end clamp 2 is connected to the side of the tensile machine 1 facing the fixed end clamp 3, and the two ends of the butterfly optical cable are clamped by the force-applying end clamp 2 and the fixed end clamp 3;

[0011] The sample preparation method of the butterfly optical cable is as follows:

[0012] The length of the sample is 100mm. At 25mm from the upper end of the sample, the sheath skin is peeled off until only two reinforcements are left. The peeling length is 50mm. After peeling, 25mm of unpeeled area is left at both ends, and only two reinforcements are left in the middle 50mm. Then one of the reinforcements is cut off, and 2mm length is left at both ends of the cut reinforcement.

[0013] The matching insert 24 must be completely matched with the slot and be flush with the end face of the slot after assembly. At the same time, during the test, the end faces of the matching positioning element 23 and the matching insert 24 are flush with each other and the finish of the end face reaches ▽10 or above.

[0018] T3. Place the matching plug-in component in the plug-in installation area in the fixture body, and ensure that the reinforcement of the butterfly optical cable sample is placed in the center of the slot of the matching plug-in component.

[0019] T4. Connect the fixture body to the connecting device, and ensure that the top thread of the fixture body is screwed into the fixed position. At this time, the narrow surface of the butterfly optical cable in the middle of the fixture at the lower end of the tensile machine should be perpendicular to the center of the fixture.

[0020] T5. Confirm again that the reinforcement of the butterfly cable sample is placed in the center of the slot of the matching plug-in component, move the matching positioning component downward until it contacts the upper end surface of the fixture body plug-in installation area, and tighten the screws of the vertical limit hole to position it.

[0021] Follow these steps to perform the test:

[0022] S1. Sample preparation: 5 samples were prepared, with a sample length of 100 mm. At 25 mm from the upper end of the sample, the sheath was peeled off until only two reinforcements were left. The peeling length was 50 mm. After peeling, 25 mm of unpeeled area was left at both ends, and only two reinforcements were left in the middle 50 mm.

[0045] In order to clearly illustrate the technical features of this patent, this patent is elaborated in detail below through a specific implementation method and in combination with its accompanying drawings.

[0046] The present invention Figure 2-13 As shown, the butterfly optical cable has a reinforcement member arranged parallel to its axial direction, and is characterized in that the optical cable adhesion detection device includes a tensile testing machine 1, a force-applying end clamp 2 and a fixed end clamp 3, the tensile testing machine 1 and the fixed end clamp 2 are fixedly connected to the frame 4, the force-applying end clamp 2 is connected to the side of the tensile testing machine 1 facing the fixed end clamp 3, and the two ends of the butterfly optical cable are clamped by the force-applying end clamp 2 and the fixed end clamp 3; it needs to be explained that: this case aims to solve the problem of slipping of the force-applying end, therefore, the fixed end clamp 3 in this case can adopt the same traditional clamp as the prior art, and the fixed end clamp 3 only serves to fix one end of the optical cable, and the fixed end clamp 3 itself does not actively apply tension to the optical cable.

[0047] The force-applying end fixture 2 comprises a connecting device 21, a fixture body 22, a matching positioning element 23 and a matching insert 24. The connecting device 21 is detachably connected to the tensile machine 1, and the fixture body 22 is fixedly connected to the connecting device 21.

[0048] The clamp body 22 includes a front body 221 and a rear body 222. The front body 221 is fixedly connected to a side of the rear body 222 away from the connecting device 21. The rear body 222 is fixedly connected to the connecting device 21. The rear body 222 is provided with a receiving hole for accommodating a matching positioning element 23. The matching positioning element 23 is penetrated in the rear body 222, and the two are detachably connected. The matching positioning element 23 is provided with a through hole adapted to the butterfly optical cable; the front body 221 is provided with a slot for accommodating a matching plug-in 24. The matching plug-in 24 is inserted into the slot, and the matching plug-in 24 is provided with a groove 241 adapted to the reinforcement.

[0049] Before testing, take a section of butterfly optical cable and peel off the outer skin in the middle to expose the internal reinforcement, such as Figure 3 After that, one end of the butterfly optical cable is first inserted into the matching positioning element 23, and then the matching insert 24 is inserted into the slot, and the matching positioning element 23 is inserted into the through hole as a whole, so that the reinforcement member in the butterfly optical cable enters the bottom of the groove along the groove, and the matching positioning element 23 is against the matching insert 24. After the force-applying end clamp 3 is assembled, the other end of the butterfly optical cable can be clamped by the fixed end clamp.

[0050] In this way, when the tensile machine 1 applies tension to start the test, the matching positioning element 23 can stably "hold" one end of the butterfly optical cable, the groove in the matching plug 24 can stably "hold" the reinforcement, and the matching plug 24 can stably press against the cut position of the butterfly optical cable towards the end face of the matching positioning element 23. Finally, the problem of slipping between the optical cable skin and the clamp applying tension can be solved, and a series of situations that lead to inaccurate data testing, such as the test sample toppling over during the test, the test sample being squeezed and deformed, and being peeled off from the thin point of the sheath wall, can be avoided, thereby improving the accuracy of the test. Overall, it has the advantages of exquisite structure, simple assembly, good use effect, and accurate adhesion test results.

[0051] The connecting device 21 includes a base 211 and a locking nut 212. The end of the base 211 away from the clamp body 22 is detachably connected to the tensile machine through a pin, and a step ring is provided in the middle of the base 211. The outer wall of the step ring is provided with an external thread, and the locking nut 212 is connected to the step ring through a thread. Among them, the working end of the tensile machine is a sleeve with two external pin holes, and the base is also provided with an internal pin hole perpendicular to its axial direction; when in use, one end of the base can be extended into the sleeve, and the pin is inserted to complete the connection between the base and the tensile machine. After that, the locking nut 212 can be rotated toward the side where the sleeve is located until it rests on the end face of the sleeve. Finally, the stable connection between the connecting device and the tensile machine can be achieved through the cooperation of the locking nut 212 and the pin.

[0052] Furthermore, the outer wall of the locking nut 212 is gear-shaped, which is convenient for twisting with a wrench. The locking nut 212 has a certain moving space for positioning after being connected to the tensile testing machine.

[0053] The connecting device is connected to the upper end of the tensile machine. The entire assembly process is as follows:

[0054] 1. Connect the connecting device to the sleeve on the tensile machine, fix it with the latch, and tighten the locking nut to position it;

[0055] 2. Open the butterfly optical cable required for the test as required, place it in the matching positioning element, and place the matching positioning element in the fixture body;

[0056] 3. Place the matching insert in the fixture body, ensuring that the reinforcement of the butterfly cable sample is placed in the center of the groove in the matching insert;

[0057] 4. Connect the fixture body to the connecting device, and ensure that the top thread of the fixture body is screwed into the fixed position. At this time, the narrow surface of the butterfly optical cable in the middle of the fixture at the lower end of the tensile machine should be perpendicular to the center of the fixture;

[0058] 5. Confirm again that the reinforcement of the butterfly cable sample is placed in the center of the groove in the matching plug-in, move the matching positioning element downward until it contacts the upper end surface of the matching plug-in, and tighten the screws of the vertical limit hole to position it.

[0059] The above five assembly steps realize the fixed installation of a butterfly-shaped optical cable reinforcement adhesion tooling: the matching insert and the fixture body are completely fitted, and the degree of freedom is zero. The matching positioning element and the matching insert have flat surfaces and are completely fitted, and the longitudinal degree of freedom is zero after being fixed by the vertical limit hole screws.

[0060] At least one vertical limiting hole 223 is formed on the side wall of the rear body 222, and a limiting bolt threadedly connected to the vertical limiting hole 223 is provided in the vertical limiting hole 223, and the vertical limiting hole 223 is arranged along the radial direction of the receiving hole in the rear body 222. In this way, after the matching positioning element 23 is installed in the receiving hole, the limiting bolt can be installed along the vertical limiting hole 223 until the limiting bolt abuts against the matching positioning element 23, thereby realizing the detachable connection between the matching positioning element 23 and the rear body 222.

[0061] The front body 221 is also provided with a limiting slot in the middle of the slot, and the middle of the outer wall of the matching insert 24 is also provided with a limiting insert block 242 connected thereto as one body, and the limiting insert block 242 is adapted to the limiting slot.

[0062] The limiting plug block 242 and the limiting slot are both arranged perpendicular to the slot. In this way, when the matching plug sheet 24 is inserted into the slot, the limiting plug block 242 can be inserted into the limiting slot simultaneously, so that the limiting plug block 242 and the front body 221 are kept fixed in the length direction of the slot, avoiding accidental movement of the two during subsequent testing, so as to ensure the accuracy of the test results.

[0063] The core of the present invention is that the matching positioning element 23 is added to ensure vertical extraction, and the unique matching insert 24 avoids the influence of friction on the test and improves the accuracy of the test; at the same time, the following matching detection method also effectively solves the problem of slipping with the clamp that applies tension when testing products with small outer diameters of reinforcing elements.

[0064] The matching positioning element in the present invention is a cylindrical structure, and its size matches the receiving hole of the fixture body: the matching positioning element needs to pass freely in the receiving hole of the fixture body without getting stuck. The center of the matching positioning element is a through-hole structure, and the shape of the through-hole needs to match the structure of the test sample, such as round, rectangular, triangular, etc.; the end face of the matching positioning element needs to be polished, and the finish reaches ▽10 or above.

[0065] The structure of the matching plug-in in the present invention needs to match the slot in the plug-in installation area, and it can be round, rectangular, triangular, etc. Both ends of the matching plug-in need to fill the slot, and a groove that is compatible with the reinforcement and used to accommodate the reinforcement is opened at the center of the matching plug-in; the center position of the groove needs to be in a straight line with the center of the entire test device, the groove needs to run through the entire matching plug-in, and the inside of the groove needs to be polished, with a smoothness of ▽10 or above; the end face of the matching plug-in needs to be polished, with a smoothness of ▽10 or above.

[0066] The sample preparation method of the butterfly optical cable is as follows:

[0067] The sample length is 100mm. At 25mm from the upper end of the sample, the sheath is peeled off until only two reinforcements are left. The peeling length is 50mm. After peeling, 25mm of unpeeled area is left at both ends. Only two reinforcements are left in the middle 50mm. Then one of the reinforcements is cut off, and 2mm is left at both ends of the cut reinforcement. This sample preparation method is used for samples that are easy to slip and have small reinforcement components. It is different from the standard sample preparation method: the sample length is 100mm. At 25mm from the upper end of the sample, the sheath is peeled off until the end, and only reinforcements are left at 75mm.

[0068] The matching positioning element 23 needs to be able to be raised and lowered and positioned, the matching insert 24 needs to be completely matched with the slot, and be flush with the end face of the slot after assembly. At the same time, during testing, the end faces of the matching positioning element 23 and the matching insert 24 are flush with each other, and the smoothness of the end faces reaches ▽10 or above. The above requirements reduce the space for the specimen to be deformed by force, avoid the friction caused by the specimen being deformed by force during the test and affect the test results, and improve the accuracy of the test.

[0069] The center of the matching positioning element 23 is a through-hole structure, and the shape of the through-hole matches the structure of the test specimen, such as a circle, a rectangle or a triangle, etc., which solves the problem of tearing from the side when the lateral force F1 is greater than the tensile force F0. Figure 14-15 As shown, when the lateral force F1 is greater than the tensile force F0, if the butterfly optical cable is not supported, the sample will be torn from the side, thus losing the meaning of adhesion testing. However, in this case, due to the presence of matching positioning elements, the optical cable can be supported to ensure that it is only subjected to axial force.

[0070] The optical cable adhesion detection device is assembled according to the following steps:

[0071] T1. Connect the connecting device to the matching device at the upper end of the tensile machine, fix it with a latch, and turn the locking device to position it;

[0072] T2. Open the butterfly optical cable required for the test as required, place it in the matching positioning element, and place the matching positioning element in the fixture body;

[0073] T3. Place the matching plug-in component in the plug-in installation area in the fixture body, and ensure that the reinforcement of the butterfly optical cable sample is placed in the center of the slot of the matching plug-in component.

[0074] T4. Connect the fixture body to the connecting device, and ensure that the top thread of the fixture body is screwed into the fixed position. At this time, the narrow surface of the butterfly optical cable in the middle of the fixture at the lower end of the tensile machine should be perpendicular to the center of the fixture.

[0075] T5. Confirm again that the reinforcement of the butterfly cable sample is placed in the center of the slot of the matching plug-in component, move the matching positioning component downward until it contacts the upper end surface of the fixture body plug-in installation area, and tighten the screws of the vertical limit hole to position it.

[0076] Follow these steps to perform the test:

[0077] S1. Sample preparation: 5 samples were prepared in total, with a sample length of 100 mm. At 25 mm from the upper end of the sample, the sheath was peeled off until only two reinforcements were left. The peeling length was 50 mm. After peeling, 25 mm of unpeeled area was left at both ends, and only two reinforcements were left in the middle 50 mm. Then one of the reinforcements was cut off, and 2 mm was left at both ends of the cut reinforcement. For specific styles, see Figure 3 .

[0078] S2. Sample installation: Take out the matching positioning element 23, place one of the manufactured samples in the matching positioning element 23, and then place the matching positioning element 23 with the sample in the rear body 222 of the fixture body 22, insert the matching plug-in 24 into the front body 221 of the fixture body 22, and ensure that the reinforcement is placed in the groove of the matching plug-in 24, control the tensile testing machine, move it to move the sample downward, so that the other 25mm long unpeeled area of ​​the sample is moved downward, and clamp it with a fixed end fixture; after the sample is installed, it must be ensured that the test optical cable is in close contact with the matching plug-in, and at the same time, the matching positioning element is in close contact with the matching plug-in element, and then tighten the limit bolts on the fixture body.

[0079] S3. Sample test: Pull the reinforcement at a constant speed of 100mm / min, and the force value should be constantly increased. Sudden stretching should be avoided. When the force value gradually increases until the reinforcement is disconnected from the sheath of the butterfly cable, the maximum reading displayed on the tensile machine is the adhesion of the butterfly cable reinforcement;

[0080] S4, repeat the test: remove the tested sample, replace the next sample, repeat steps S2-S3, and obtain the adhesion of the reinforcement in the next sample; until all the five samples made in step S1 are tested, take the average of the five valid values ​​to obtain the test data of this test. (Abnormal data caused by sudden stretching or other reasons are not considered as valid values ​​and need to be retested.

[0081] There are many specific implementation ways of the present invention. The above is only the preferred implementation mode of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principle of the present invention. These improvements should also be regarded as the protection scope of the present invention.

Confirm again that the reinforcement of the butterfly cable sample is placed in the center of the slot of the matching plug-in component, move the matching positioning component downward until it contacts the upper end surface of the fixture body plug-in installation area, and tighten the screws of the vertical limit hole to position it.

7. An adhesion detection method based on the butterfly optical cable adhesion detection device with strong reinforcement adhesion as claimed in claim 1 or 2, characterized in that: Follow these steps to perform the test: S1. Sample preparation: 5 samples were prepared, with a sample length of 100 mm. At 25 mm from the upper end of the sample, the sheath was peeled off until only two reinforcements were left. The peeling length was 50 mm. After peeling, 25 mm of unpeeled area was left at both ends, and only two reinforcements were left in the middle 50 mm. Then one of the reinforcements was cut off, and 2 mm of length was left at both ends of the cut reinforcement. S2. Sample installation: Take out the matching positioning element (23), place one of the manufactured samples in the matching positioning element (23), then place the matching positioning element (23) containing the sample in the rear body (222) of the fixture body (22), insert the matching insert (24) into the front body (221) of the fixture body (22), and ensure that the reinforcement is placed in the groove of the matching insert (24), control the tensile machine, move it to move the sample downward, make another 25 mm long unpeeled area of ​​the sample downward, and clamp it with a fixed end clamp; S3. Sample test: Pull the reinforcement at a constant speed of 100mm / min, and the force value increases constantly. When the force value gradually increases until the reinforcement is disconnected from the sheath of the butterfly cable, the maximum reading displayed on the tensile machine is the adhesion force of the butterfly cable reinforcement; S4, repeat the test: remove the tested sample, replace it with the next prepared sample, repeat steps S2-S3, and obtain the adhesion of the reinforcement in the next sample; until all the five samples prepared in step S1 are tested, take the average of the five measured valid values ​​to obtain the test data of this test.
