Description

Technical Field

[0001] The present invention relates to a batch electrical conduction test device, and more particularly to a conduction test device for a DS6-60 terminal board. Background Art

[0002] For the conventional conduction test of a PCB board, a simple solution can be to directly measure it with a multimeter.

[0003] However, for a DS6-60 terminal board, due to its high integration level, when manually measuring with a multimeter, it is easy to cause a short-circuit fault due to inaccurate control, resulting in the accidental contact of the test leads, and further causing damage to the circuit board.

[0004] In addition, when multiple-channel tests are required, the test results need to be recorded one by one. First, it is impossible to intuitively reflect which channel is not conducting. Especially when several circuit boards need to be compared, it is impossible to quickly and intuitively reflect the comparison situation. Second, due to the excessive continuous test volume, it will cause local fatigue of the personnel, increasing the incidence of short circuits.

[0005] In the prior art, usually, the test leads of the multimeter are improved to reduce their conductive area to reduce short-circuit accidents, but the problem of low test efficiency still cannot be solved. In addition, after reducing the conductive area of the test leads, the test efficiency will be further reduced. Summary of the Invention

[0006] The purpose of the present invention is to provide a conduction test device for a DS6-60 terminal board. The power supply is divided into multiple paths through a power supply splitter, and a main circuit switch is provided. The main circuit power supply can be connected after all paths are connected, so as to avoid short circuits caused by accidental contact during the wiring process and prevent the board from being burned out. In addition, through a feedback branch provided with light-emitting diodes, the integrity of each circuit to be tested can be clearly and intuitively known.

[0007] The purpose of the present invention can be achieved by the following technical solutions:

[0008] A conduction test device for a DS6-60 terminal board includes a DC power supply module, a main circuit switch, a power supply splitter, a wiring module, and multiple feedback branches.

DETAILED DESCRIPTION

[0026] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0027] A DS6-60 terminal board conduction test device includes a DC power supply module 4, a main switch 7, a power supply splitter 8, a wiring module and multiple feedback branches, the feedback branch includes a branch switch 13 and a light-emitting diode 14 connected in series in sequence, one end of the main switch 7 is connected to the positive electrode of the DC power supply module 4, and the other end is connected to the female end of the power supply splitter 8, each sub-end of the power supply splitter 8 is respectively connected to the first end of multiple circuits to be tested on the tested terminal board 9, the second end of each circuit to be tested is respectively connected to one end of each corresponding feedback branch via the wiring module, and the other end of the feedback branch is connected to the negative electrode of the DC power supply module 4.

[0028] The power supply is divided into multiple paths through the power supply splitter 8, and a main circuit switch 7 is provided. The main power supply can be turned on after all paths are connected, thereby avoiding short circuits caused by accidental touches during the wiring process and avoiding board burnout. In addition, the feedback branch provided with a light-emitting diode 14 can clearly and intuitively know the integrity of each circuit to be tested.

[0029] In almost all embodiments, a fuse 6 is provided between the main switch 7 and the DC power supply module 4 to protect the safety of the test circuit.

[0030] In addition, the input end of the DC power supply module 4 is connected to the lighting electrical connection 1 through the rocker switch 4 and the power socket 2 in turn. Generally, a fuse 6 can also be set between the power socket 2 and the rocker switch 4. In this design, the DC power supply module 4 is an AC / DC module. The input of the AC / DC module is 220V AC and the output is 5V DC. The specific model can be NES-50-5.

[0031] In some embodiments, the device further includes a box body. The wiring module includes a first electrical connector 10, a second electrical connector 11, and a third electrical connector 12. The main circuit switch 7, the power supply splitter 8, the third electrical connector 12, and all feedback branches are arranged inside the box body. Each input end of the first electrical connector 10 is respectively connected to the second end of each circuit under test, and each output end is respectively connected to each input end of the second electrical connector 11. Each output end of the second electrical connector 11 is respectively connected to each input end of the third electrical connector 12, and each output end of the third electrical connector 12 is respectively connected to each feedback branch. The wiring module is composed of multiple electrical connectors. Based on three electrical connectors, the part separated from the terminal board under test 9 can be subjected to interface conversion, and the subsequent interfaces can be designed to be matched, so that a part can be fixed inside the box body. While simplifying the wiring during testing, the overall neatness is also improved, and errors are avoided.

[0032] Since the third electrical connector 12 and the power supply splitter 8 located inside the box body 15 are not convenient to change, they are relayed through the first electrical connector 10 and the second electrical connector 11, which can improve the reliability of the line connection.

[0033] In some embodiments, the main circuit switch 7, and the branch switches 13 and light-emitting diodes 14 of all feedback branches are all located on the surface of the box body, which is easy to operate.

[0034] In certain embodiments, the second electrical connector 11 and the third electrical connector 12 are connected by a buckle, which improves the convenience of line connection during testing.

[0035] Generally, the main circuit switch 7 is a micro toggle switch. Similarly, the branch switch 13 is a micro toggle switch.

[0036] The device further includes a main circuit indicator light 3. One end of the main circuit indicator light 3 is connected to the output end of the main circuit switch 7, and the other end is connected to the negative pole of the DC power supply module 4.

[0037] In this embodiment, the power supply splitter 8 adopts a rectangular electrical connector 5535043-4, and the third electrical connector adopts a rectangular electrical connector CS-TX19-5.08×10.16-36ZC.

[0038] The 220V AC power is converted into 5V DC power by the DC power supply module 4. The power is divided into 34 paths by the power supply splitter 8 and supplied to the terminal board under test respectively, so that multiple circuits of the terminal board under test can be measured simultaneously. After the power comes out of the terminal board under test 9, it passes through the first electrical connector 10, the second electrical connector 11 and the third electrical connector 12, and then each path is connected to the branch switch 13 of the corresponding feedback branch respectively. After passing through the current limiting resistor and the light emitting diode 14, it reaches the negative pole of the DC power supply module 4, forming a closed loop. After the DC power supply module 4 converts the power into 5V DC power, there is a main switch as the total switch. After the 5V DC power passes through the terminal board under test 9, it is divided into multiple signal outputs, and the on-off of each output is independently controlled by the branch switch 13, and the light emitting diode 14 indicates the test result. Two fuses 6 play a role in overload protection.

[0039] In this application, the test loop of each path of the terminal board is separately displayed by the light emitting diode 14, which is intuitive, convenient and easy to observe, and there is no need to record the test results after testing one by one. And connectors are equipped, and the DC power supply module 4 and the test circuit are integrated in a box 15, which is convenient for direct connection with the terminal board under test 9, and the test is simple and clear.
