When we tested the refrigerator compressor electrical seal terminal (Fig. 1), the clamp shown in Figure 2 was used. The compression screw 3 and the clamp 1 were screwed together. When the pressure was applied, a slight tilt was generated, and the workpiece and the clamp were specific. The sealing ring 4 cannot be closed. After improvement, the 45° inclined surface of the part which is in contact with the workpiece is clamped, and an isosceles triangular boss (Fig. 3) with a height of 0.5 mm is pulled out and hardened to HRC 40 to 45. Meet the 18MPa pressure test.
