Technical Field
[0001] This utility model relates to the field of power equipment technology, specifically to an insulating housing for a rectifier. Background Technology
[0002] A rectifier is an electronic device that converts alternating current (AC) to direct current (DC). It is widely used in various industrial, commercial, and household electrical systems. During operation, the high voltage and high current environment inside a rectifier requires its casing to have good insulation properties to prevent safety hazards such as current leakage, short circuits, and electric shock. Therefore, developing an insulating casing for a rectifier is particularly important.
[0003] Referring to the insulating housing of a rectifier with reference announcement number CN211859968U, the housing includes a device body, which comprises a base box and a cover. The base box and the cover are connected by a fixing device, which includes a latch and a latching block. The latch is fixed to the cover, and the latching block is fixed to the outer surface of the base box on the same side. A slot is provided in the center of the top of the cover, and a handle is movably disposed in the slot. The base box includes an upper box and a lower box, which are integral structures. A shock-absorbing device is provided at the bottom of the lower box, and the shock-absorbing device includes an upper plate and a lower plate. The upper plate and the lower plate are... A shock-absorbing spring is fixed in the middle, and a cavity is opened on the bottom surface of the upper plate. Through the device body and the rubber ring device, after the user puts the rectifier into the box, the material and structural characteristics make the rectifier wrapped in the insulation device. In the event of leakage during use, it will not be transmitted to the outside through the device body. As can be seen from the above, although the insulation shell can be used well, it usually does not have a related heat dissipation structure, making it difficult to dissipate heat from the rectifier body. This makes the rectifier body prone to burning due to high temperature, which often troubles users. Utility Model Content

[0028] In use, the upper sealing frame 4 is set to accommodate the upper lock seat 12;
