Abstract
The utility model relates to a testing device for a diode, and especially relates to a rapid testing device for reverse direction voltage of a diode, comprising a testboard. Two leads pass through and are fixed on the testboard; one ends of the leads are connected with a compression resistance instrument of reverse direction; and the other ends passing thorugh the testboard are extended outwards to form a placing rail of a diode. The detection rate and the production efficiency are greatly increased; and production cost is reduced, after the above structure is adopted.
Description
Technical field
The utility model relates to the device for quick testing of a kind of diode detection device, particularly a kind of diode reverse voltage.
Background technology
After diode production is finished, need carry out voltage-withstand test to the reverse voltage of diode.In the prior art, be directly diode to be connected with withstand voltage instrument, feed reverse voltage, see whether detection meets the withstand voltage standard of diode.
Because the turnout of diode is very big, and the reverse withstand voltage disqualification rate of diode is very low, a diode is directly connected to detect on the withstand voltage instrument can make that the efficient that detects is very low, consumes very big manpower and materials if all be at every turn.
Summary of the invention
The utility model technical issues that need to address provide whether standard compliant proving installation of a kind of quick test diode reverse voltage.
In order to solve above-mentioned technical matters, diode reverse voltage device for quick testing of the present utility model comprises test board, and two leads pass test board and are fixed on the test board; One end of lead is connected on the reverse withstand voltage instrument, and the other end that passes test board outwards extends and forms the placement track of diode.
After adopting said structure, during test, the two ends of a plurality of diodes are placed on respectively on the placement track of proving installation, feed reverse voltage.Utilize the principle of diode reverse leakage current stack in parallel, if having oppositely withstand voltage non-compliantly in the diode of certain group test, significant change can take place in the waveform of diode reverse leakage current on withstand voltage instrument; This moment diode is just chosen one by one and can be detected underproof diode.Because the disqualification rate of the reverse voltage of diode test is very low, with the detection in parallel of a plurality of diodes, improved detection rates and production efficiency greatly like this, reduced production cost.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model diode reverse voltage device for quick testing.
Fig. 2 is the side sectional view of the utility model diode reverse voltage device for quick testing.
Among the figure: 1 is test board, and 2 is lead, and 3 for placing track, and 4 is clip, and 5 are bending
Embodiment
As depicted in figs. 1 and 2, diode reverse voltage device for quick testing of the present utility model comprises that 1, two lead 2 of test board passes test board and is fixed on the test board 1; One end of lead 2 is connected on the reverse withstand voltage instrument, and the other end that passes test board outwards extends and forms the placement track 3 of diode.There is insulated hull the end outside that lead 2 is connected to withstand voltage instrument, and the placement track 3 of lead 2 other ends is plain conductors that the outside does not have insulated hull, places track 3 like this and can well contact with the two ends of required test diode.
Described as shown in Figure 1 lead 2 is that one in 4, two clips of clip are red with the link of reverse withstand voltage instrument, and another one is a black, can make the convenient placement diode of test man like this and feed reverse voltage.
The tail end that the diode that described as shown in Figure 2 lead 2 outwards extends is placed track 3 upwards bends 5, in the time of like this on one group of diode being placed on placement track 3, can prevent that diode is from placing the tail end landing of track 3.
Test process is as follows: one group of diode is successively placed on places on the track 3 the cathode and anode directions unanimity of all diodes.Clip 4 is connected to the input end of withstand voltage instrument, feed reverse voltage after, the waveform of observation reverse leakage current.If reverse leakage current waveform and standard have bigger fluctuation, then proving in this group diode has reverse voltage underproof, and diode is chosen one by one, and what then choose before when the tilde standardization is defective.Because diode reverse voltage defective very low, so it oppositely withstand voltagely can improve checkability greatly by the group test.
The utility model is not limited to the structure of embodiment illustrated in figures 1 and 2.The metal material of lead of the present utility model can be other metal materials that are suitable for.The clip that is connected with withstand voltage instrument also can be the connected mode of crotch.Such conversion all drops within the protection domain of the present utility model.
