[0018] Example 1, refer to Figures 1-4 A liquid pressure test fixture, comprising a liquid tank 1, characterized in that the upper surface of the liquid tank 1 is fixed with a bottom fixed plate 2 through a bolt, the inside of the bottom fixed plate 2 is horizontally embedded with a spring top post 201, the upper part of the spring top post 201 is embedded with a spring top post push-pull screw 202, one end of the bottom fixed plate 2 near the middle of the liquid tank 1 is fixed with an electrode fixing block 3 through a bolt, and one end of the electrode fixing block 3 near the middle of the liquid tank 1 is horizontally embedded with an electrode screw 301.

[0019] Four bottom fixed plates 2 are arranged on the upper surface of the liquid tank 1, and the bottom fixed plates 2 are symmetrically arranged around the horizontal or vertical central axis of the liquid tank 1;

[0020] After the product or wire package is put into the liquid tank 1, 10% sodium chloride solution is added into the liquid tank 1, the product or wire package is completely immersed in the liquid, the lead wire is fixed on the electrode fixing block 3 by penetrating the wire hole, and then the test positive and negative electrodes of the withstand voltage tester are clamped on the electrode screws 301 of the corresponding two windings, the air conductivity is better than the liquid conductivity when power is supplied, so when each of the two wire packages has a pinhole, the withstand voltage must be poor, which greatly improves the detection of the withstand voltage of the product, and the detection effect is better;

[0021] The embedded hole in the inner hole of the electrode fixing block 3 is provided, and the vertical cutting area of the embedded hole is consistent with the vertical cutting area of the spring top column 201;

[0022] The spring top column 201 slides horizontally left and right in the bottom fixed plate 2, and the spring top column 201 is located outside the entrance of the embedded hole in the electrode fixing block 3;
