Miscellaneous, element is various and the hidden danger that occurs big, high in cost of production shortcoming.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of able to programme double
Source current sensor.
To achieve these goals, the one dual power supply able to programme current sensor designed by this utility model,
Including upper end open and the shell of hollow form, the flowing hole being arranged in shell and be set in flowing hole with
C-type magnetic core between shell, described c-type magnetic core has aperture slots, and described aperture slots is embedded with can
Programming linear Hall plate, described proframmable linear Hall plate is fixedly arranged on wiring board lower surface, described wiring board
Upper surface is provided with terminal, and described terminal electrically connects with proframmable linear Hall plate, tool in the middle of described wiring board
There is the through hole passed for flowing hole.
Further, described terminal all welds in the circuit board with proframmable linear Hall plate.
Further, described outer casing inner wall is provided with locating part, and described locating part is positioned at aperture slots.
Further, described flowing hole is coaxially disposed with shell.
4 pins are set on terminal, are respectively defined as positive pole, negative pole, output and ground connection, able to programme
Four pins are also set on linear Hall sheet and by the wire on wiring board and the pin one a pair on terminal
Should connect, and the power supply of this proframmable linear Hall plate is negative and positive dual power form, then may be used
Program in the aperture slots that linear Hall plate is embedded into c-type magnetic core, then by c-type magnetic core together with wiring board etc.
It is put in shell at shell aperture, and makes flowing hole pass the through hole on wiring board, now, locating part
It is positioned at aperture slots and c-type magnetic core is carried out spacing, then toward encapsulated epoxy resin in shell, it is carried out
Encapsulation, wears in flowing hole and penetrates copper bar or cable, i.e. can measure the electric current by copper bar Yu cable.
When not having electric current to pass through in flowing hole, the voltage of terminal output pin output is millivolt level, is no better than
No-voltage, when there being electric current to pass through in flowing hole, will produce magnetic field in the aperture slots of c-type magnetic core,
The size in magnetic field changes with the size variation flowing through electric current, able to programme in c-type magnetic core aperture slots
Linear Hall sheet is magnet-sensitive element, will export a certain proportion of voltage when sensing magnetic field and from end
