Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0041] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral body; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0042] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0043] Example

[0044] First, see Figure 1~Figure 5 The present embodiment provides a withstand voltage test machine, including a detachable protective cover, a withstand voltage test fixture and a movable connection component, the withstand voltage test fixture is used to contact the positive pin of the product to be tested, and the connection component is used to contact the negative pin of the product to be tested to form a closed loop and perform a power-on test on the product to be tested.

[0045] The protective cover and the connecting parts are both existing equipment. This embodiment mainly improves the defects of the existing voltage resistance test fixture. The voltage resistance test fixture provided in this embodiment includes a base 1, a baffle 2, an aluminum bar 31, a power cord 4, a pressure plate 5, and a scale bar 6.

[0046] The upper side of the base 1 is provided with a first groove 11 and a second groove 12 along its length direction, the first groove 11 and the second groove 12 are connected to each other on one side, the depth of the first groove 11 is greater than the depth of the second groove 12, and the width of the first groove 11 is less than the width of the second groove 12. In a specific implementation scenario, the depth of the first groove 11 is 4 mm and the width is 14 mm, and the depth of the second groove 12 is 2 mm and the width is 18 mm.

[0047] The lower part of the baffle 2 is engaged in the first groove 11. In this embodiment, the baffle 2 is L-shaped, and an installation gap is left between the vertical part of the baffle 2 and the pressing plate 5, and the lower side of the plate-like conductive structure 3 is in contact with the upper side of the horizontal part of the baffle 2.

[0048] The aluminum strip 31 is placed flat in the second groove 12, and a plurality of aluminum strips 31 are arranged in abutment with each other in the width direction of the second groove 12 to form a plate-like conductive structure 3, and the upper side of the plate-like conductive structure 3 is flush with the upper side of the base 1. The upper side of the plate-like conductive structure 3 is used to contact the positive electrode pin of the product to be tested. In this embodiment, the length of the plate-like conductive structure 3 is 405 mm, and 25 products to be tested can be arranged in a row on its upper side.

[0049] The power line 4 is connected to the plate-shaped conductive structure 3 .

[0050] The pressing plate 5 is fastened to the upper side of the base 1 by two hexagon socket screws 51. The bottom of the pressing plate 5 can contact the upper side of the plate-like conductive structure 3, and the bottom of the pressing plate 5 presses the plate-like conductive structure 3 tightly into the second groove 12 to limit the plate-like conductive structure 3. In this embodiment, since the lower side of the plate-like conductive structure 3 is in contact with the upper side of the lateral portion of the baffle 2, after tightening the two hexagon socket screws 51, the plate-like conductive structure 3 and the baffle 2 can be fixed at the same time.

[0051] The scale bar 6 is located in the installation gap and fixed on the vertical portion of the baffle 2. In a specific implementation scenario, the bottom of the scale bar 6 is in contact with the upper side of the plate-shaped conductive structure 3.

[0052] It is understandable that, since the plate-like conductive structure 3 is connected to the power line 4, it should be made of conductive material, and other components (base 1, baffle 2, pressure plate 5, scale bar 6) are preferably made of insulating material.

[0053] The plate-shaped conductive structure 3, the baffle 2 and the pressing block together form a storage slot with three inner walls, and the three sides are perpendicular to each other. The storage slot is equivalent to a notch formed after a part is "bitten" off at the top corner of a block, so as to facilitate loading and unloading by horizontal pushing and sweeping, and facilitate the arrangement of multiple products to be tested.

[0054] When in use, first open the protective cover, then take out 25 products to be tested from the finished product tray, arrange them in a line in the storage slot, cover the protective cover, turn on the withstand voltage tester, move the connection component downward, make the connection component press the negative pin of the product to be tested, and perform a power-on test; move the connection component horizontally so that it contacts the negative pin of each product to be tested one by one, thereby completing the withstand voltage test of the 25 products to be tested; after the test is completed, turn off the withstand voltage tester, open the protective cover, put in the finished product tray, and push the product into the finished product tray.

[0055] In other embodiments, the test efficiency may be further improved by increasing the number of connected components.

[0056] In combination with the above content, the above-mentioned withstand voltage test fixture has at least the following beneficial effects:

[0057] 1. In this embodiment, the length of the plate-shaped conductive structure 3 is 405 mm, and 25 products to be tested can be arranged in a row on its upper side, which improves the test efficiency by more than ten times.

[0058] It should be noted that in other implementation scenarios, the length of the plate-like conductive structure 3 only needs to be greater than or equal to three times the length of the product to be tested, that is, greater than or equal to three products to be tested can be placed on the plate-like conductive structure 3 .

[0059] Second, a storage slot with three inner walls is formed by enclosing a plate-like conductive structure 3, a baffle 2 and a pressure block. The three sides are perpendicular to each other, which is convenient for loading and unloading the products to be tested. That is, the present application changes the traditional embedded loading and unloading method to a flat or open loading and unloading method, thereby improving the efficiency of loading and unloading.

[0060] 3. By setting the first groove 11 and the second groove 12 and the L-shape of the baffle 2, an installation gap is left between the vertical portion of the baffle 2 and the pressure plate 5, and the lower side of the plate-like conductive structure 3 is in contact with the upper side of the horizontal portion of the baffle 2, so that after tightening the two hexagon socket screws 51 (other fastening components can also be used), the plate-like conductive structure 3 and the baffle 2 can be fixed at the same time.

[0061] It is understandable that other methods can be used to connect the plate-shaped conductive structure 3 and the baffle 2 to the base 1. When the pressing plate 5 is not used for fixing, the plate-shaped conductive structure 3 and the baffle 2 can be enclosed to form a storage groove with two inner walls, and the two sides are perpendicular to each other.

[0062] Fourth, by setting the scale bar 6, it is convenient to arrange each product to be tested in a suitable position.

[0063] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. In the absence of conflicts, the embodiments of the present application and the features in the embodiments may be combined with each other at will. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
