Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of optical cable testing, in particular to a multifunctional optical cable tensile testing machine. BACKGROUND

[0002] Optical cable is a communication cable composed of optical fiber as the core transmission unit, supplemented by protective layer, reinforcing member, etc., used for long-distance and large-capacity transmission of optical signals. Its core includes optical fiber (high-purity quartz glass or plastic) that transmits light by total reflection, plastic protective layer, and steel wire or aramid fiber reinforcing member, with the characteristics of large transmission capacity, long distance, strong anti-interference, good security, and lightness, widely used in communication network, broadcast television, power and military communication fields. During the production of optical cable, optical cable tensile testing machine is needed to test the performance of optical cable.

[0003] In the prior art, the patent document with publication number CN113432960B discloses a multifunctional optical cable tensile testing machine. The device includes a base, a fixed frame is provided on the surface of the base, a gas cylinder is fixed on the inner top of the fixed frame, a first positioning structure and a second positioning structure are respectively provided on the surface of the base and the bottom of the gas cylinder, and a protective cover is movably installed on the surface of the fixed frame. The first positioning structure includes a positioning box, a first motor is fixed inside the positioning box, and the output shaft of the motor is connected to a connecting block. The device preliminarily clamps one end of the optical cable through the relative movement of the two fixed plates, and then drives the rotating cylinder to rotate by the connecting block to complete the fixation of the end of the optical cable, thereby reducing the manual operation steps. However, the device still has the following problems: when clamping and fixing the optical cable, only clamping force is applied from both sides, which will cause uneven distribution of clamping force in this single-point stress mode, making the optical cable prone to slipping during tensile testing, affecting the stability and accuracy of test data. More importantly, when increasing the clamping force to prevent slipping, the local pressure concentration will cause the stress imbalance of the cross section of the optical cable, which may cause the outer protective layer to be crushed and cracked, and even damage the internal optical fiber structure. This not only directly damages the optical cable sample, but also may cause the optical cable to break at an unexpected position, resulting in that the test result cannot truly reflect the actual tensile performance, seriously affecting the scientificity and reliability of the test.
