Device for detecting whether surface of cable needing to be laid for communication is damaged

Abstract

The invention relates to the technical field of communication, and discloses a device for detecting whether the skin of a cable needing to be laid for communication is damaged or not. The device comprises a housing, a power detection mechanism is movably connected to the interior of the housing, a connecting block is fixedly connected to the upper end of the power detection mechanism, and a limiting block is movably connected to the left end of the connecting block. The upper end of the connecting block is fixedly connected with a compression spring, the upper end of the compression spring is fixedly connected with a fixing block, the left end of the fixing block is movably connected with an indicating lamp, and a protective shell is fixedly connected to the left end of the indicating lamp and located at the upper end of the inner wall of the housing. In the moving process of the cable in the housing, when it is detected that the skin is damaged and the internal wire is exposed, the internal current passes through the power detection mechanism at the moment, so that the current is carried in the power detection mechanism, the current flows through the interior of the indicator lamp, the indicator lamp is lightened, and the effect of warning external personnel is achieved.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a device for detecting whether the skin of a cable laid for communication is damaged. Background technique [0002] In ancient times, communication was generally transmitted through letters or oral dictation, which often took a long time to transmit, but modern communication can quickly transmit information through Internet connections, so as to achieve efficient implementation, facilitate people's communication, and make communication The required cables are also laid across the country. [0003] However, there are still defects that need to be overcome in the detection of cables in the current communication. After the cable is processed, the skin may be damaged under the action of external force or the environment, so that the internal wires of the cable are exposed to the outside air, which may cause damage to the cable for a long time. The internal circuit of...

[0003] However, there are still defects that need to be overcome in the detection of cables in the current communication. After the cable is processed, the skin may be damaged under the action of external force or the environment, so that the internal wires of the cable are exposed to the outside air, which may cause damage to the cable for a long time. The internal circuit of the cable is faulty, which causes losses, but it is difficult to detect whether there is any damage to the skin. Therefore, a device for detecting whether the skin of the cable that needs to be laid for communication is damaged came into being.
