[0028] In the description of the present application, unless otherwise explicitly limited, the words such as setting, installing, connecting, etc. should be broadly understood, and the person skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical scheme.
[0029] In the communication industry, the quality of communication cables is directly related to the stability and reliability of information transmission. Communication cables are usually conductive wire structures covered with protective wire sleeve structures, such as network cables, which are a common type of communication cable. To ensure that the communication cable can withstand the expected tension without breaking or performance degradation during use, it is necessary to conduct a tension test on the communication cable. In traditional technology, a clamping structure is usually used to clamp both ends of the cable, and then a tensile force is applied to the communication cable to achieve the tension test. This tension test structure concentrates the force on the end of the communication cable. During the tension test, not only is the communication cable easily damaged due to excessive pressure at the clamping contact position, but the communication cable is also easily offset from the clamping structure, resulting in inaccurate test results.
[0030] On the other hand, the traditional fixing method lacks flexibility and is difficult to adapt to the testing needs of communication cables of different specifications and lengths. The existing tension test device cannot accurately control the stretching speed and displacement of the cable during testing, which affects the accuracy and repeatability of the tension test. At the same time, for communication cables that need to simulate complex stress conditions in actual use environment, the traditional tension test device often cannot provide sufficient testing dimensions and accuracy.
[0031] The following refers to the accompanying drawings that Figure 1 to the accompanying drawings that Figure 4 The tension test device for communication cables of the embodiments of the present application can effectively protect the communication cables and accurately and reliably perform the tension test with high efficiency.

[0036] By setting the first winding wheel 120 and the second winding wheel 250 for winding the communication cable, the contact area between the communication cable and the winding wheel can be effectively increased, thereby effectively balancing the interaction force, avoiding damage to the communication cable or inaccurate test results due to excessive pressure at the connection, allowing the communication cable to be closer to the actual stress state during the tensile test, and effectively improving the accuracy and reliability of the tensile test; the translation adjustment mechanism 210 in the second positioning assembly can adjust the position of the translation seat 220 relative to the first winding wheel 120, thereby effectively adapting to the test requirements of communication cables of different lengths and specifications, not only effectively improving the versatility and flexibility of the tensile test, but also simplifying the winding and straightening operation of the communication cable, effectively reducing the difficulty of the tensile test, and improving the efficiency of the tensile test. By driving the second winding wheel 250 to translate away from the first winding wheel 120 through the stretching drive test mechanism 230, the stretching speed and displacement of the communication cable can be controlled, and the accuracy and repeatability of the tensile test can be significantly improved.
