Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that the high-voltage detecting device of a kind of Full-plastics sealed element, it is possible to the High-Voltage Insulation characteristic of convenient disposable detection large area product.
According to the technical scheme that this utility model provides, the high-voltage detecting device of described Full-plastics sealed element includes: top board, electrode, insulation strip, testing base, the side of described top board and testing base is connected through the hinge, top board is provided with electrode, testing base is provided with test trough and insulation strip, detected product is placed in test trough, the laminating of bottom surface and test trough bottom surface, the current-carrying part of detected product and insulation strip docile；When top board and testing base pressing, described electrode is fitted with detected product upper surface；During detection, high voltage is applied in detected product by electrode and testing base.
Concrete, described testing base is one piece of conductive metal sheet, and insulation strip is embedded in testing base.Described top board adopts insulant, and electrode is embedded in top board.
Described electrode, test trough are strip.Insulation strip is positioned at by test trough.
The utility model has the advantages that: adopt can the top board structure of free-open-close, testing base designs test trough, coincide with test product profile；Testing base is inlayed lower insulation strip, makes product current-carrying part can insulate with electric conductor, it is possible to the High-Voltage Insulation characteristic of disposable detection large area product.
Figure of description
Fig. 1 is the structural representation of this utility model open mode.
Fig. 2 is the structural representation after this utility model places detected product.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, high-voltage detecting device of the present utility model includes top board 1, electrode 2, insulation strip 4, testing base 5, the side of described top board 1 and testing base 5 is connected by hinge 3, top board 1 is provided with electrode 2, testing base 5 is provided with test trough 6 and insulation strip 4.
Described testing base 5 is one piece of conductive metal sheet, and the shape detecting product above as required opens test trough, makes detected product 7 docile being placed in test trough 6 of energy.Testing base 5 has been inlayed a bar insulation bar 4.
Top board 1 adopts insulant, and top board 1 has been inlayed an electrode made by conductive metallic material 2.Being connected by hinge 3 between top board 1 and testing base 5, top board 1 can movable downwards and and testing base 5 pressing.
As in figure 2 it is shown, detected product 7 is placed in the test trough 6 of testing base 5, and fit with test trough 6 bottom surface in the bottom surface of detected product 7, and insulation strip 4 is positioned at test trough 6 side, the current-carrying part of detected product 7 and insulation strip 4 docile；Top board 1 can downwards with testing base pressing 5, during pressing, the electrode 2 that top board 1 is inlayed is fitted with detected product 7 upper surface.
This utility model is applicable to semi-conductor discrete device encapsulation field, is used for the plastic-sealed body the testing Full-plastics sealed element tolerance to 2500V voltage.During detection, high voltage (2500V) is applied on product by electrode 2 and testing base 5.Top board 1 of the present utility model can folding swimmingly, electrode 2, insulation strip 4, test trough 6 are both designed as strip, it is possible to detect longer product.
When testing multiple small pieces, by disposable for the small pieces marshalling high-voltage detecting device putting into this utility model design, contrasting background technology, this utility model can test 16 products for 0.3 second, and efficiency improves 16 times, and production capacity is promoted to 192K per hour.
