Description

Technical Field

[0001] This utility model relates to the field of optical cable technology, specifically to a testing device for the bending performance of optical cables. Background Technology

[0002] Optical cables are manufactured to meet optical, mechanical, or environmental performance specifications. They are communication cable assemblies that use one or more optical fibers placed in a sheath as the transmission medium and can be used individually or in groups. Optical cables are mainly composed of optical fibers, plastic protective sheaths, and plastic outer sheaths. Bending tests on optical cables are conducted to ensure that the cables can withstand expected bending without damage in actual use. This requires testing equipment for the bending performance of optical cables. Currently, the equipment on the market for testing the bending performance of optical cables involves suspending a weight at the lower end of the cable and observing the degree of wear on the cable's surface by swinging it back and forth. This allows the maximum number of times the cable can be bent back and forth to obtain the bending performance of the optical cable.

[0003] When conducting bending tests, the data measured at different bending angles often show certain differences, which can illustrate the different performance and indicators of optical cables under different usage scenarios; therefore, a testing device for the bending performance of optical cables is proposed.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention ensures the optical cable is vertical by fixing a weight to its lower end. The cable is placed between a first and second clamping plate, and a threaded rod is rotated to bring the second clamping plate closer to the first, thus clamping and fixing the cable. A motor drives a lead screw to rotate, which in turn moves the nut seat and a moving plate left and right. The moving plate then moves a rack left and right, and the gear meshing with the rack drives a turntable to rotate back and forth, adjusting the turntable's rotation angle. By comparing the first clamping plate with the scale lines and the number of rotations, the maximum number of bends the cable can be determined at different angles. During bending tests, the motor can control the turntable's rotation at different angles, allowing for the acquisition of different performance characteristics and indicators of the optical cable under various usage scenarios. The measured data is more comprehensive and practical. Attached Figure Description

[0022] Please refer to the accompanying drawings in the specification. This utility model provides a technical solution: a testing device for the bending performance of optical cables, including a base plate 1, a mounting frame 2 fixedly connected to the upper surface of the base plate 1, a motor 3 fixedly mounted on the right surface of the mounting frame 2, a lead screw 4 fixedly connected to the output shaft end of the motor 3, the lead screw 4 passing through the right surface of the mounting frame 2, a mounting groove 5 opened on the front surface of the mounting frame 2, the lead screw 4 and the inner wall of the mounting groove 5 being rotatably connected by a bearing, a nut seat 6 threadedly connected to the outer wall of the lead screw 4, a moving plate 7 fixedly connected to the front surface of the nut seat 6, a rack 8 uniformly welded to the lower surface of the moving plate 7, a turntable 9 rotatably connected to the front surface of the mounting frame 2 via a bearing, a gear 10 fixedly connected to the outer wall of the turntable 9, the rack 8 and the gear 10 meshing with each other, a first clamping plate 11 fixedly connected to the front surface of the turntable 9, a second clamping plate 12 provided on the right side of the first clamping plate 11, a threaded rod 13 threadedly connected to the inner wall of the first clamping plate 11, the threaded rod 13 and the second clamping plate 12 being connected to the first clamping plate 11. The left side walls of the two clamping plates 12 are rotatably connected by bearings. The front surface of the mounting bracket 2 is evenly coated with scale lines 14. The lower end of the optical cable is fixed with a weight to ensure that the optical cable is in a vertical state. The optical cable is placed between the first clamping plate 11 and the second clamping plate 12. The threaded rod 13 is rotated to bring the second clamping plate 12 closer to the first clamping plate 11, thus clamping and fixing the optical cable. At this time, the lowermost ends of the first clamping plate 11 and the second clamping plate 12 are at the center of the turntable 9. The motor 3 drives the lead screw 4 to rotate. The lead screw 4 drives the nut seat 6 and the moving plate 7 to move left and right. The moving plate 7 drives the rack 8 to move left and right. The gear 10 meshing with the rack 8 drives the turntable 9 to rotate back and forth, thereby adjusting the rotation angle of the turntable 9. Since the lowermost end of the second clamping plate 12 is at the center of the turntable 9, the angle at which the optical cable is bent is the rotation angle of the turntable 9. By comparing the first clamping plate 11 with the scale lines 14 and the number of back and forth rotations, the maximum number of times the optical cable is bent at different angles can be obtained.

[0023] In this embodiment, specifically: a limiting block 15 is fixedly connected to the lower surface of the nut seat 6, a limiting groove 16 is fixedly connected to the lower surface of the inner sidewall of the mounting groove 5, and the outer sidewall of the limiting block 15 and the inner sidewall of the limiting groove 16 are slidably connected; so that the nut seat 6 does not rotate with the rotation of the lead screw 4, but moves left and right along the direction of the limiting groove 16.

[0024] In this embodiment, specifically: a knob 17 is fixedly connected to the left end of the threaded rod 13; rotating the knob 17 causes the threaded rod 13 to rotate.

[0025] In this embodiment, specifically: two limiting rods 18 are fixedly connected to the left side wall of the second clamping plate 12, and the outer side wall of the limiting rods 18 is slidably connected to the first clamping plate 11; so that the second clamping plate 12 moves away from or closer to the first clamping plate 11.

[0026] In this embodiment, specifically: two guide shafts 19 are rotatably connected to the lower end of the front surface of the mounting bracket 2, and guide rollers 20 are fixedly connected to the outer side wall of the guide shafts 19; when in use, the optical cable is passed through the middle of the two guide rollers 20 to prevent damage caused by the swinging of the optical cable.

[0027] In this embodiment, specifically: a first arc plate 21 is fixedly connected to the lower surface of the first clamping plate 11, and a second arc plate 22 is fixedly connected to the lower surface of the second clamping plate 12; to prevent the optical cable from breaking accidentally.

[0028] In this embodiment, specifically: four legs 23 are welded to the lower surface of the base plate 1 to support the base plate 1.

[0029] In this embodiment, specifically: the right side of the front surface of the mounting bracket 2 is provided with an operation panel 24.

[0030] The working principle of this utility model is as follows: A weight is fixed to the lower end of the optical cable to ensure it is vertical. The optical cable is placed between the first clamping plate 11 and the second clamping plate 12. The threaded rod 13 is rotated, causing the second clamping plate 12 to move closer to the first clamping plate 11, thus clamping and fixing the optical cable. At this time, the lowermost ends of the first clamping plate 11 and the second clamping plate 12 are at the center of the turntable 9. The motor 3 drives the lead screw 4 to rotate, which in turn drives the nut seat 6 and the moving plate 7 to move left and right. The moving plate 7 then drives the rack 8 to move left and right, and the gear 10 meshing with the rack 8 drives the turntable 9 to rotate back and forth. Adjusting the rotation angle of turntable 9, since the lowest end of the second clamping plate 12 is located at the center of turntable 9, the angle at which the optical cable is bent is the rotation angle of turntable 9. By comparing the first clamping plate 11 with the scale line 14 and the number of back-and-forth rotations, the maximum number of times the optical cable is bent at different angles can be obtained. This constitutes a test device for the bending performance of optical cables. During the bending test, the turntable 9 can be rotated at different angles by the motor 3, thereby obtaining different performance and indicators of the optical cable under different usage scenarios. The measured data is more comprehensive and more practical.
