Description

Technical Field

[0001] The utility model relates to the field of detection technology; specifically, the utility model relates to a testing device for voltage resistance samples. Background Art

[0002] In the breakdown voltage resistance experiment, the ceramic coating and metal substrate on the surface of the sample need to be connected, the positive electrode contacts the ceramic film, and the negative electrode contacts the metal substrate. However, there is no suitable test device on the market, and two people need to work together, one holding the sample and the other using an electric pen to test. During the experiment, if the two people do not cooperate well, the positive and negative electrodes will not be aligned properly and cannot be accurately connected, which will affect the accuracy of the experimental data and make the experiment unable to proceed normally. In addition, there is a risk of the high-voltage electric pen falling off, which poses a very high safety hazard to the operator. Utility Model Content

[0005] A first electrode pen support plate is disposed at the upper end between the first support column and the third support column, and a second electrode pen support plate is disposed at the upper end between the second support column and the fourth support column. Both the first electrode pen support plate and the second electrode pen support plate are arc-shaped.

[0006] In the aforementioned testing device, optionally, a first sample supporting plate is disposed at the lower end between the first supporting column and the second supporting column, and a second sample supporting plate is disposed at the lower end between the third supporting column and the fourth supporting column.

[0007] In the aforementioned testing device, optionally, the cross-sections of the first supporting column, the second supporting column, the third supporting column and the fourth supporting column are circular.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: in the breakdown voltage resistance experiment, the experimental sample is placed on the first sample support plate and the second sample support plate, and leans against the second support column and the fourth support column. The first electrode pen support plate and the second electrode pen support plate are used to place the positive electrode pen and the negative electrode pen, thereby avoiding the human experimental error caused by the offset of the test point that may be caused by long-term testing, ensuring the accuracy of the experiment, and reducing the number of people holding the sample, so that only one person is needed to complete the experiment.

[0015] Figure 1 The schematic diagram of the structure of the test device for voltage resistance samples of the utility model is shown in the figure, which includes a base 1, a first support column 2, a second support column 3, a third support column 4, a fourth support column 5, a first electrode pen support plate 6, and a second electrode pen support plate 7 of the test device, and the whole test device is made of insulating materials.

[0016] like Figure 1 As shown, the first support column 2, the second support column 3, the third support column 4 and the fourth support column 5 are arranged on the upper end surface of the base 1, and the first support column 2, the second support column 3, the third support column 4 and the fourth support column 5 are respectively located at the four corners of the rectangle. A first electrode pen support plate 6 is arranged at the upper end between the first support column 2 and the third support column 4, and a second electrode pen support plate 7 is arranged at the upper end between the second support column 3 and the fourth support column 5. The first electrode pen support plate 6 and the second electrode pen support plate 7 are both arc-shaped. The first electrode pen support plate 6 and the second electrode pen support plate 7 are used to support the positive electrode pen and the negative electrode pen.

[0017] Furthermore, a first sample support plate 8 is disposed at the lower end between the first support column 2 and the second support column 3, and a second sample support plate 9 is disposed at the lower end between the third support column 4 and the fourth support column 5. The first sample support plate 8 and the second sample support plate 9 are used to place samples.

[0018] Furthermore, the cross-sections of the first support column 2, the second support column 3, the third support column 4 and the fourth support column 5 are circular, the sample is placed on the first sample support plate 8 and the second sample support plate 9 and leans against the second support column 3 and the fourth support column 5, and the sample is in sheet form. Since the cross-sections of the second support column 3 and the fourth support column 5 are circular, point contact is made between the sample and the second support column 3 and the fourth support column 5, thereby reducing the contact area between the sample and the second support column 3 and the fourth support column 5, reducing the risk of voltage being absorbed, and reducing the contact area can reduce the possibility of sample contamination and increase the testable area of ​​the sample.

[0019] In combination with the above embodiments of the utility model, during the operation of the voltage resistance sample testing device, the sample is placed in the testing device, that is, the bottom of the sample is at the first sample support plate 8 and the second sample support plate 9, and is leaning against the second support column 3 and the fourth support column 5. The positive electrode detection pen is placed on the first electrode pen support plate 6, and the negative electrode detection pen is placed on the second electrode pen support plate 7. The positive electrode detection pen contacts the ceramic membrane of the sample, and the negative electrode detection pen contacts the metal substrate of the sample. Of course, an operator is still required to hold the ends of the positive electrode detection pen and the negative electrode detection pen.

[0020] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
