Description

Technical Field

[0001] The invention relates to the technical field of coaxial cable detection, in particular to a coaxial cable detection device. Background Art

[0002] Coaxial cable is a type of cable consisting of an inner conductor surrounded by a concentric conductive shield, separated by two dielectrics (insulating materials). Many coaxial cables also have a protective outer jacket or sheath. The term "coaxial" refers to the inner conductor and outer shield that share a geometric axis. Coaxial cable is a transmission line used to transmit high-frequency electrical signals with low loss. It is used in applications such as telephone trunks, broadband Internet cables, high-speed computer data buses, cable television signals, and connecting radio transmitters and receivers to antennas. It differs from other shielded cables in that the dimensions of the cable and connectors are controlled to provide precise, constant conductor spacing, which is necessary for its effective use as a transmission line. Coaxial cable is used as a transmission line for radio frequency signals. Its applications include feed lines that connect radio transmitters and receivers to antennas, computer network (such as Ethernet) connections, digital audio (S / PDIF), and the distribution of cable television signals. One advantage of coaxial cable over other types of radio transmission lines is that in an ideal coaxial cable, the electromagnetic field carrying the signal exists only in the space between the inner and outer conductors. This allows coaxial cable traces to be installed next to metal objects without the power losses that occur in other types of transmission lines. Coaxial cable also protects the signal from external electromagnetic interference.

[0003] The physical properties of coaxial cables need to be tested before leaving the factory, including tensile strength, bending strength and anti-twisting ability. During the test, the above three properties need to be tested on three different devices. The frequent replacement of equipment is inefficient and has low practicality.
