Background
The shielded cable is a transmission line in which signal lines are wrapped with a metal mesh braid. The braid is typically red copper or tin-plated copper. The wire and cable industry is the second largest industry next to the automobile industry, and the product variety satisfaction rate and the domestic market share are both over 90 percent. Along with the high-speed development of the wire and cable industry, the number of newly-increased enterprises is continuously increased, and the whole technical level of the industry is greatly improved. For example, the invention has the technical application publication number CN114566322a, and is a buried high-temperature-resistant shielding cable, which comprises a cable body and a connection seat, wherein the cable body penetrates through the interior of the connection seat, the outer surface of the connection seat is fixedly connected with a supporting seat, the interior of the supporting seat is fixedly connected with a shielding seat, the side surface of the shielding seat is provided with a connection assembly, one side of the connection assembly is connected with a sealing assembly, the connection assembly comprises a toggle rod which is rotationally connected with the side surface of the shielding seat, the outer surface of the toggle rod is rotationally connected with a rotating rod, and one side of the rotating rod is connected with a push plate. Through when the bull stick drives the push pedal and removes, the push pedal can stimulate telescopic link and extension spring of its one side simultaneously, and telescopic link and extension spring can reduce the vertical load force that cable junction received this moment, avoid cable junction atress suddenly and destroy the phenomenon of articulated department wire, improved the life of cable self.
Shielding is to ensure the transmission performance of the system in an electromagnetic interference environment, and the anti-interference performance here should include two aspects, namely, the capability of resisting external electromagnetic interference and the capability of the system itself to radiate electromagnetic interference outwards. For example, the technology disclosed in the application publication number CN114264851a is a method for measuring electromagnetic shielding attenuation of a shielded cable, which is used for measuring electromagnetic shielding attenuation of a shielded cable to be measured; the current calibration device is connected in series between the tested shielding cable and the signal source cable on the nonmetal support, the other end of the signal source cable is connected with the signal source, and the other end of the tested shielding cable is connected with a load; the measurement method comprises a reference measurement on the current calibration device and an attenuation measurement on the measured shielded cable; the attenuation measurement comprises a near-end measurement close to the position of the current calibration device and a far-end measurement which is carried out by arranging a current probe at a position spaced by a distance M from the near-end measurement, wherein the maximum value is an attenuation measurement value; the measure of the masked attenuation is equal to the ratio of the reference measure to the attenuation measure or the difference between the logarithmic unit measure of the reference measure and the logarithmic unit measure of the attenuation measure. In theory, the cable and the connector are covered with a metal shielding layer, so that unnecessary electromagnetic waves can be effectively filtered, however, for the shielding system, the shielding layer is insufficient, and more importantly, the shielding layer must be well grounded, so that interference current can be effectively led into the ground.
However, in the actual laying process of the shielded cable, for example, when the shielded cable is laid on a wall, the laying party hopes that the shielded cable is laid straight, so that on one hand, electromagnetic interference can be reduced, the working performance of the laid cable is ensured, and on the other hand, the waste of the cable can be reduced as much as possible, and the price and cost for laying the shielded cable on the wall are reduced. However, the lack of a corresponding high-precision actual length measurement mechanism in the prior art makes it difficult to reliably identify the degree of the laying relaxation of each shielded cable, and thus increases in the cost of laying the cable and decreases in the quality of laying are likely to occur.
