The invention discloses a line fracture protection printed board. The line fracture protection printed board includes a printed board body and a power source circuit which is arranged on the printed board body and is used for providing a working power source; the printed circuit board body is also provided with a time base oscillation circuit for generating control signals, and a push-pull circuit which controls the switch-on or switch-off of the power source circuit through the control signals, wherein the push-pull circuit is connected with the time base oscillation circuit and the power source circuit respectively. According to the line fracture protection printed board of the invention, the time base oscillation circuit and the push-pull circuit are arranged on the printed board body, and the push-pull circuit controls the on-off of the power source circuit through the control signals, and therefore, line fracture protection of lines and cables can be effectively realized, and errors caused by wiring can be decreased; after the printed circuit board is modularized, the printed circuit board can be produced in a batched manner, and therefore, production cost can be decreased, and production efficiency can be improved.
Description
technical field [0001] The invention relates to the technical field of cable disconnection protection, in particular to a disconnection protection printed board. Background technique [0002] The cables of mobile devices often need to be dragged back and forth, which will wear and scratch the cables, resulting in damage to the cable insulation, resulting in leakage. In the prior art, external devices such as leakage protectors, circuit breakers, and fuses are generally used to realize the leakage protection of cables, but this method increases the difficulty of wiring and increases the production cost. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing a modularized disconnection protection printed board with low production cost. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technical scheme: [0005] The disconnection protection printed boa...
