Description

Technical Field

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

[0002] A data cable is a cable used to transmit data between electronic devices. It can not only transmit digital information such as files, pictures, and videos, but also provide power to devices in many cases. It is an indispensable tool in people's daily lives. Data cables often need to undergo various physical operations such as bending and folding. Therefore, in order to simulate real-world usage environments, bending tests are conducted to simulate these real-world usage scenarios and evaluate the durability of data cables under such conditions.

[0003] Existing data cable bending test devices typically involve manually fixing the data cable to a clamp with wear-resistant padding materials such as rubber on its surface, and then performing various bending tests. Manual fixing usually takes more time than automated fixing, which greatly reduces the overall testing efficiency. Moreover, it is difficult to ensure that the fixing force and position are completely consistent each time, which will affect the reliability of the test results.

[0004] Therefore, a data cable bending test device is proposed to solve the problems mentioned above. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0026] Please see Figure 1 - Figure 7 The data cable bending test device in this embodiment includes one or more gear shafts 21 in groups of two. A gear cylinder 22 meshes with the surface of the gear shaft 21. The gear cylinder 22 is arc-shaped. A fixing plate 23 is fixedly installed on the inner surface of the gear cylinder 22. Each group of fixing plates 23 is interlocked with each other. A motor 20 is provided on the mounting surface of the gear shaft 21.

[0027] A protective shell 19 is provided on the outside of the gear cylinder 22. The gear shaft 21, gear cylinder 22, and fixing plate 23 are all inside the protective shell 19. The upper half of the protective shell 19 has the same curvature as the gear cylinder 22. A threaded rod 18 is provided on the lower half of the protective shell 19. A motor 24 is fixedly installed at one end of the threaded rod 18. A workbench 4 is provided on the outside of the protective shell 19.

[0028] Among them, motor 4 20 and motor 5 24 are electrically connected to the external power line. The gear shaft 21 rotates in the opposite direction under the drive of motor 4 20. The two fixing plates 23 rotate upward under the drive of gear cylinder 22 until they are in contact and stop rotating. The protective shell 19 moves linearly on the threaded rod 3 18 under the drive of motor 5 24, flattening the data cable and fixing the outer sheath of the data cable. Then, the two ends of the data cable are tightened by external clamps to carry out the bending test operation, which can achieve automatic fixing and avoid the problems of low testing efficiency and instability under manual operation.

[0029] The upper surface of the workbench 4 has several slots 15. The lower surfaces of the front and rear ends of slot 15 have slots 2 16. The lower surface of slot 2 16 has holes 17. The threaded rod 3 18 is located inside the hole 17. The arc-shaped surface of the protective shell 19 is the same as that of slot 15.

[0030] The protective shell 19 is located inside the limiting space formed by the slot 2 16 and the hole 17. The upper surface of the protective shell 19 is flush with the worktable 4. Before the fixing operation, the two protective shells 19 are located in similar positions inside the limiting space to avoid uneven data cables. They are first fixed from the middle position and then moved to both ends to improve the fixing efficiency.

[0031] A support platform 5 is provided below the workbench 4. A vibration device 7 is fixedly installed on the upper surface of the support platform 5. The workbench 4 is fixedly installed on the upper surface of the vibration device 7. Two support frames 1 are fixedly installed on the upper surface of the support platform 5.

[0032] The vibration device 7 can make the data cable move slightly on the surface of the workbench 4 through continuous and regular vibration until it reaches the optimal position, namely slot 15, so that the data cable can make fuller contact with slot 15 and ensure that the fixing plate 23 can fix it completely.

[0033] One or more electric telescopic rods 6 are fixedly installed on the lower surface of the support frame 1. The electric telescopic rods 6 are fixedly installed on the upper surface of the support platform 5. Threaded rods 13 are fixedly installed inside the support frame 1. One end of the threaded rod 13 is smooth. Fixing blocks 11 are sleeved on the outer sides of both ends of the threaded rod 13. Motors 8 are fixedly installed on the mounting surface of the threaded rod 13.

[0034] Among them, the second motor 8 is electrically connected to the external power supply line. The fixing block 11 located at the smooth end of the threaded rod 13 remains in a fixed position when the second motor 8 drives the threaded rod 13. The fixing block 11 at the other end of the threaded rod 13 can move closer to it to avoid the fixing block 11 at one end getting stuck and affecting the working efficiency.

[0035] A rotating rod 14 is inserted through the lower half of the fixing block 11. A motor 3 9 is installed at one end of the rotating rod 14, and a fixing member 10 is fixedly installed at the other end of the rotating rod 14. A motor 1 3 is fixedly installed on the upper surface of the fixing member 10. A threaded rod 12 is fixedly installed at the output end of the motor 1 3. A clamping plate 2 is sleeved on the outside of the threaded rod 12. Two clamping plates 2 are a group and are symmetrically distributed vertically. The lower surface of the lower clamping plate 2 is fixedly connected to the lower half of the fixing member 10.

[0036] The fixing parts 10 are arranged in relative positions. Both motor 3 and motor 9 are electrically connected to the external power line. The threaded rod 12 does not contact the lower clamping plate 2. When the outer sheath of the data cable is fixed, motor 3 drives the threaded rod 12, causing the upper clamping plate 2 to descend and gradually contact the lower clamping plate 2 until the data cable connector is fixed. Motor 9 drives the rotating rod 14, causing the fixing parts 10 and clamping plate 2 to rotate as a whole. The data cable can be wrapped around the surface of clamping plate 2 to complete the bending test.

[0037] The direction of threaded rod 13 is consistent with that of groove 15, and clamping plate 2 is perpendicular to threaded rod 13;

[0038] Among them, threaded rod 13 and clamping plate 2 are located outside the workbench 4. The length of slot 15 is not greater than the length of the data cable being tested, so that the connectors at both ends of the data cable being tested can fully extend out of the workbench 4, and clamping plate 2 can fix them normally.

[0039] The surface of clamp 2 is semi-circular arc, and the lengths of clamp 2 and threaded rod 13 are both greater than the corresponding lengths of the workbench 4.

[0040] Both the clamping plate 2 and the threaded rod 13 can move away from and closer to the worktable 4 under the push of the electric telescopic rod 6, so that the clamping plate 2 does not affect the data cable fixing operation of the worktable 4 and avoids the worktable 4 from being bumped during the rotation and movement of the clamping plate 2.

[0041] The working principle of the above embodiments is as follows:

[0042] In use, the data cable is laid on the upper surface of the workbench 4 along the direction of slot 15. The vibration device 7 starts running, causing the data cable to slide into the inside of slot 15. Motors 4 20 and 5 24 are electrically connected to the external power cord. The gear shaft 21 rotates in the opposite direction under the drive of motor 4 20. The two fixing plates 23 rotate upward under the drive of gear cylinder 22 until they are in contact and stop rotating. The protective shell 19 moves linearly on the threaded rod 3 18 under the drive of motor 5 24, flattening the data cable and fixing the outer sheath of the data cable. The electric telescopic rod 6 drives the clamping plate 2 to move down to fix both ends of the data cable. At this time, the fixing plate 23 returns to the inside of the protective shell 19 under the drive of motor 4 20. The electric telescopic rod 6 pushes the clamping plate 2 upward away from the workbench 4. Motor 3 9 drives the clamping plate 2 to rotate. Motor 2 8 drives the clamping plate 2 to move to the other end of the threaded rod 2 13 to perform a bending test. This achieves automatic fixing and avoids the problems of low testing efficiency and instability under manual operation.

[0043] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
