Among them, manual insertion and extraction is limited by human power, unable to perform high-intensity insertion and extraction tests, with a large labor intensity and low work efficiency. At the same time, there may be misdetection due to human negligence. Among them, the cost of the high-precision positioning instrument is relatively high, which is not conducive to manufacturers reducing the testing cost. Summary of the Utility Model

Fixing frames are symmetrically arranged on both sides of the conveyor belt in the conveying direction, so that the plugs at both ends of the data cable can be simultaneously fixed in two symmetric fixing frames. Plugging and unplugging mechanisms are symmetrically arranged on both sides of the support frame in the conveying direction, and the plugging and unplugging mechanisms correspond to the fixing frames. The plugging and unplugging mechanism includes a telescopic element, a proximity switch, and a plug socket.

A limiting block is arranged in the fixing clamping plate. The top of the limiting block is U-shaped, and the two fixing clamping plates form a U-shaped structure, both including a top clamping plate and a bottom support plate. The top clamping plates on both sides extend to the top of the limiting block and are partially located within the U-shaped portion of the limiting block for cooperating with the limiting block to place the data cable plug. The bottom support plates on both sides are L-shaped and are staggeredly symmetrically distributed at the bottom of the placement groove. A lever is arranged between the two bottom support plates. The lever is respectively matched with the bottom support plates on both sides in a manner capable of rotating horizontally through a pin shaft, and the pin shaft is close to the middle position of the limiting block.

[0025] Referring to Figures 1 to 3 , an embodiment of the present application provides a data cable pulling force testing device, which includes a support frame 10 and a conveyor belt 20 disposed on the support frame 10 and capable of rotating directionally. Wherein, on both sides of the conveyor belt 20 in the conveying direction, fixing frames 30 are symmetrically arranged, so that the plugs at both ends of the data cable can be simultaneously fixed in two symmetrically arranged fixing frames 30. In addition, on both sides of the support frame 10 in the conveying direction, plugging and unplugging mechanisms 40 are symmetrically arranged, and the plugging and unplugging mechanisms 40 correspond to the fixing frames 30. Specifically, the plugging and unplugging mechanism 40 includes a telescopic element 41, a proximity switch 42, and a plug socket 43. Among them, the telescopic element 41 is preferably implemented as a telescopic cylinder, or can also be a telescopic electric cylinder. At the same time, the plug socket 43 is fixedly arranged at the top of the telescopic rod 411 of the telescopic element 41 and faces the fixing frame 30 in the conveying direction. In addition, a force sensor 412 is also installed on the telescopic rod 411 for measuring the pulling force when the plug socket 43 is pulled out from the data cable plug when the telescopic rod 411 moves. Correspondingly, a groove adapted to plug the data cable plug is provided at the inner end of the plug socket 43. In addition, an induction element cooperating with the proximity switch 412 is provided on the fixing frame 30.

[0026] Specifically, when measuring the pulling force of the data cable plug, first fix the plugs at both ends of the data cable in two symmetrically distributed fixing frames 30. The conveyor belt 20 rotates directionally. When the proximity switch 42 senses that the fixing frame 30 has moved into place through the sensing element, the conveyor belt 20 stops running. The telescopic element 41 controls the telescopic rod 411 to extend, so that the groove of the plug socket 43 is inserted into the data cable plug. Then the telescopic element 41 retracts and resets. During the retraction and reset process, the maximum pulling force sensed by the pulling force sensor 412 is the maximum pulling force of the data cable plug. Furthermore, in this way, the pulling force tests on the two plugs on the same data cable can be automatically completed simultaneously. The operation is convenient, the work efficiency is high, the equipment cost is low, and the misdetection caused by human error can also be avoided.

[0027] In one embodiment, the proximity switch 42 is located directly below the plug socket 13.

[0028] In one embodiment, the conveyor belt 20 is arranged on the top of the support frame 10 and extends in the horizontal direction to facilitate the installation and testing of the data cable to be tested. The support frame 10 is provided with a driving roller 11 and a driven roller 12 for rolling and supporting the conveyor belt 20, and a rotating motor 13 for driving the driving roller 11 to rotate. The motor rotating shaft of the rotating motor 13 coaxially drives the driving roller 11 to rotate and cooperates with the driven roller 12 to drive the conveyor belt 20 to rotate.

[0029] In one embodiment, the fixing frame 30 includes a fixing seat 31. A wire groove 301 extending in a direction perpendicular to the conveying direction is provided on the top of the fixing seat 31, so that the wire body of the data cable can be placed through the wire groove 301, and the plugs at both ends of the data cable can be fixed on the fixing frame 30. The fixing seat 31 is also provided with a placement groove 302 at the outer end of the wire groove 301, and at the same time, fixed clamps 32 are symmetrically provided on both sides close to the groove wall in the placement groove 302, and an elastic member 33 is provided between the fixed clamps 32 and the groove wall. In addition, a limiting block 34 is provided in the fixed clamps 32, wherein the top of the limiting block 34 is U-shaped, and the two fixed clamps 32 form a U-shaped structure, both including a top buckle plate 321 and a bottom support plate 322, wherein the top buckle plates 321 on both sides extend to the top of the limiting block 34, and are partially located in the U-shape of the limiting block 34, for cooperating with the limiting block 34 to place a data line plug, wherein the bottom support plates 322 on both sides are L-shaped, and are staggered and symmetrically distributed at the bottom of the placement groove 302, and a lever 323 is provided between the two bottom support plates 322. The lever 323 is respectively matched with the bottom support plates 322 on both sides through a pin shaft 324 in a manner that it can rotate in the horizontal direction, and the pin shaft 324 is close to the middle position of the limit block 34. At the same time, the top wall and bottom wall of the placement groove 302 are respectively slidably matched with the fixed clamping plate 32.

[0030] During the installation process, first, the lever 323 is moved to open the fixed clamps 32 on both sides under the limiting action of the placement groove 302, and the data line plug is placed in the U-shaped space surrounded by the top buckle plate 321 and the limiting block 34. During this period, the elastic member 33 always provides elastic force to push the fixed clamps 32 relatively close, so that the data line plug can be firmly fixed. When the plug-in test is completed, the lever 323 is moved to drive the fixed clamps 32 on both sides to move relatively away, and the limiting action of the top buckle plate 321 is lost, so that the data layer plug can be taken out of the limiting block 34.

[0031] In one embodiment, the elastic member 33 is implemented as a V-shaped elastic plate or a V-shaped spring.

[0032] In one embodiment, the cross-section of the portion of the top buckle plate 321 extending to the top of the limit block 34 is in a right-angled trapezoid, and the long bottom side of the right-angled trapezoid is close to the limit block 34 and slides with the top of the two side ends of the limit block 34, so that the data cable plug can be limited by the top position of the hypotenuse and the long bottom side. Once the fixed splint 3 moves outward, the inner upper position of the top buckle plate 321 will provide a larger unloading space, and the data cable plug can be quickly detached from the placement slot 302. Similarly, this shape can also facilitate the data cable plug to be quickly put into place during testing.

[0033] In one embodiment, one end of the lever 323 away from the wire groove 301 extends to the outside of the fixed seat 31. At the same time, the support frame 10 is symmetrically provided with stoppers 14 that cooperate with the lever 323 on both sides of the conveyor belt 20. The stoppers 14 are located at the trailing end close to the conveying direction and below the conveyor belt 20. Thus, during the rotation of the conveyor belt 20, the lever 323 can be blocked by the stopper 14 to make the dial 323 rotate automatically, so as to automatically open the fixed clamp 32, and then the data line plug can automatically fall under its own weight, realizing automatic unloading, thereby further improving the work efficiency.

[0034] Further preferably, a dial 15 is provided between the two symmetrically distributed stoppers 14 of the support frame 10. At the same time, the dial 15 extends along the width direction of the conveyor belt and extends a predetermined distance upward in the direction perpendicular to the extending direction, so as to block the wire body part of the data line after the conveyor belt 20 conveys the fixed frame over. Thus, by combining the stopper 14 to block the data line plug, it can be ensured that the data line can automatically fall along the dial 15 after the test is completed, thereby ensuring the reliability of automatic unloading and the certainty of the blanking position.

[0035] In one embodiment, there are multiple groups of the fixed frames 30, and the multiple groups of the fixed frames 30 are evenly spaced along the conveying direction of the conveyor belt 20. Thus, continuous automatic testing of the data line plugs can be achieved by this testing device, thereby effectively improving the testing efficiency.

[0036] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and described in the embodiments. Without departing from the above principles, the embodiments of the present invention can have any deformation or modification.
