Abstract
The utility model provides a shifting device whose power supply outputs multiple currents, comprising current-limiting resistances and a switching device. The utility model is characterized in that the at least two current-limiting resistances are provided and are respectively connected to the switching device. Compared with the prior art, the utility model is advantageous in that the supply of the same voltage and different currents can be facilitated, the testing on the circuit board by testing staffs is facilitated, and the circuit shifting is effectively simplified; the use is convenient, the design is reasonable, the structure is simple and the use value is quite high.
Description
1, technical field
Specifically a kind of power supply of the utility model is exported the switching device shifter of multiple electric current.
2, background technology
In process to circuit board testing, need carry out the different electric current of same voltage and come same circuit board is tested, need test each stage of whole process during test.And existing test mode need ceaselessly be carried out the switching of circuit, and very loaded down with trivial details of operating process is unfavorable for the test of tester to circuit board very much.
3, summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of power supply to export the switching device shifter of multiple electric current.
The technical solution of the utility model realizes that in the following manner its structure is made of current-limiting resistance, switch, and current-limiting resistance is provided with 2 at least; The current-limiting resistance that is provided with is connected with switch respectively.
Above-mentioned current-limiting resistance and switch are arranged in parallel.
The utility model has the advantages that:
A kind of power supply of the present utility model is exported the switching device shifter of multiple electric current and is compared with prior art, can provide identical voltage different electric currents easily, being convenient to the tester tests circuit board, effectively simplify the loaded down with trivial details degree that circuit switches, and the utility model also has easy to use, characteristics such as reasonable in design, simple in structure, thereby, good use value had.
4, description of drawings
Fig. 1 exports the structural representation of the switching device shifter of multiple electric current for a kind of power supply.
5, embodiment
Do following detailed description the in detail below in conjunction with the switching device shifter that accompanying drawing is exported multiple electric current to a kind of power supply of the present utility model.
As shown in Figure 1, its structure of switching device shifter that a kind of power supply of the present utility model is exported multiple electric current is made of current-limiting resistance, switch, and current-limiting resistance is provided with 2 at least; The current-limiting resistance that is provided with is arranged in parallel with switch respectively.
In power up, power supply passes through change-over switch again to each circuit supply after by current-limiting resistance, regulates corresponding electric current by control its switch and controls output current on this circuit, realizes the test job of circuit board.
In the test process, if there is not change-over switch, the tester needs deenergization that circuit is carried out the circuit blocking processing; After connecting change-over switch, the tester does not need deenergization, and directly commutation circuit gets final product.
It is very simple and convenient that a kind of power supply of the present utility model is exported its processing and fabricating of switching device shifter of multiple electric current, can process shown in the accompanying drawing to specifications.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
