Abstract
The utility model provides a function test tool for a signal control module. The function test tool comprises a power supply circuit, a current-limiting circuit, and a LED display circuit. The power supply circuit is used for providing a stable direct-current voltage for the whole circuit. The current-limiting circuit is used to play a current-limiting protection role in the whole circuit. The LED display circuit is used for providing an indicator light display function for the test of the whole circuit. The function test tool has advantages of a small size, a simple structure and easy operation, and is applicable to test the signal control module. According to the utility model, electrical performance failures can be judged through the judgment of program functions, power signals and control signals.
Description
Technical field:
The utility model relates to a kind of functional test frock, particularly a kind of functional test frock of signal controlling module.
Background technology:
In the electron trade manufacture process, the several factors that is restricting production efficiency and quality all has close getting in touch with the testing apparatus that every money product matches, the functional test frock of prior art; Volume is big, the unprotect lid; Must connect D.C. regulated power supply, operate cumbersome, difficult mobile.
The utility model content:
The utility model is just in order to solve the problems of the technologies described above, and a kind of volume of design little, outer box protection is arranged, save the AC/DC current regulator power supply, directly connect a power lead and import 90～265Vac alternating current and get final product.
A kind of functional test frock of signal controlling module; Comprise feed circuit, current-limiting circuit, LED display circuit; Said feed circuit are that entire circuit provides galvanic current to press; Said current-limiting circuit has played the effect of current-limiting protection to entire circuit, and the test that said LED display circuit is an entire circuit provides pilot lamp demonstration effect.
The functional test frock of said signal controlling module, said feed circuit connect current-limiting resistance and power light is that circuit provides galvanic current to press.
The functional test frock of said signal controlling module, said current-limiting circuit realizes current-limiting protection through current-limiting resistance, avoids excessive electric current to pass through, and burns out electronic devices and components.
The functional test frock of said signal controlling module, said LED display circuit through the bright of test light emitting diode with do not work, come determining program function, power supply signal and control signal whether normal, then can judge whether fault of product electric property.
The functional test frock of said signal controlling module; Volume is little; Outer box is made by aluminium material, has an aperture that power light is emerging in the outside on the aluminium lid, and other LED light all is emerging in the outside and makes things convenient for test operation; Supply socket and switch are installed in the side, and the input end that is connected with four lines and the output terminal that is connected with eight lines be direction in the same side.
Description of drawings:
Accompanying drawing is the test fixture circuit diagram of the utility model.
Embodiment:
Engaging accompanying drawing and specific embodiment below further describes the utility model.
Shown in accompanying drawing, be the test fixture circuit diagram of the utility model, comprise feed circuit, current-limiting circuit, LED display circuit, said feed circuit are at the alternating current of input end input 90～265Vac, and through an AC-DC converter, converter is exported 5V and 24V.Output 5V DC voltage connects LED light emitting diode D7 and current-limiting resistance R1, and wherein LED light emitting diode D7 is the sign that has or not power supply as display power supply.Bright like power light, prove power supply, power light does not work, and proving does not have power supply, and more whether decision circuitry has problem through just estimating to make people.When of the power supply of output 24V direct current as power circuit, connect diode D8 and played anti-reverse hypotensive effect, also played the current-limiting protection effect simultaneously.And D8 connects two ports, and port connects the P3 connector, promptly connects the input port of tested power module, and as the power supply power supply of tested power module, another port connects 2 normally closed switchs, is respectively K1, K2 and 2 normal open switch K5, K6.K5 connect P2 connector 1 pin and with the LED5 conducting, LED5 is connected with R9 again, R9 has played the current-limiting protection effect to tested power module, P2 connects the output port of tested power module, the PG of K3, K4 connection AC-DC converter.Said current-limiting circuit is R2, R3, R4, R5, R6, R7 and R8, R9, and effect all is a current limliting, and said LED display circuit is that LED1, LED2, LED3, LED4, LED6 are identical with the effect of LED5, and wherein EG is a earth, and SG is a signal ground, and PG is a Power Groud.
Particularly; The alternating current that earlier the supply socket connecting line is directly connected 90～265Vac during operation behind tested power module success write-in program, breaks off alternating current; And break off being connected of tested power module and programmable device, directly carry out tested power module then and transfer and survey operation.
The utility model test fixture volume is little, and outer box is made by aluminium material, has an aperture that power light is emerging in the outside on the aluminium lid, and other LED light all is emerging in aspect, outside test operation, and supply socket and switch are installed in the side.
As stated, be the most preferred method of the utility model.
