Problems solved by technology
[0002] Surveying equipment is generally used for field exploration. The existing equipment is to connect the detection instrument with a power supply or a battery. In the prior art, it is only connected through a simple power line. It is easy to reverse the connection during actual operation. Operating without knowing it can easily cause damage to the survey equipment. At the same time, the existing power cord has no fault indication function, and the operator needs to return to the maintenance point for maintenance, which delays the survey time

The invention discloses a safe instrument power line. The power line comprises a power supply input interface, an instrument plug and a protection device arranged between the power supply input interface and the instrument plug; the protection device comprises a shell, an indicating lamp and a circuit board; the circuit board is fixed in the shell, indicating lamps are embedded in the outer side of the shell, the indicating lamps comprise a normal indicating lamp, an overvoltage indicating lamp, an undervoltage indicating lamp and a reverse connection indicating lamp, and the normal indicatinglamp, the overvoltage indicating lamp, the undervoltage indicating lamp and the reverse connection indicating lamp are connected with the circuit board. The safe instrument power line adopting the structure has a reverse connection prevention function and a common fault indication function, is convenient for workers to adjust in time, and saves exploration time.
Description
technical field [0001] The invention relates to a power cord, in particular to a safe instrument power cord. Background technique [0002] Surveying equipment is generally used for field exploration. The existing equipment is to connect the detection instrument with a power supply or a battery. In the prior art, it is only connected through a simple power line, which is easy to be reversed during actual operation. Operating without knowing it can easily cause damage to the survey equipment. At the same time, the existing power line has no fault indication function, and the operator needs to return to the maintenance point for maintenance, which delays the survey time. Contents of the invention [0003] The purpose of the present invention is to provide a safe instrument power cord with anti-reverse connection function and common fault indication function, which is convenient for staff to adjust in time and saves exploration time. [0004] In order to achieve the above obj...
