Problems solved by technology
However, since the spraying of metal screws requires a special process, the processing technology is complicated and the cost is high, and in order to ensure the cost, the screws are packaged and transported in batches, and the insulation layer is easily worn out during transportation, causing the insulation to fail.
[0005] In order to solve the above problems, some companies also use plastic screws and ceramic screws instead of metal screw connections to solve this problem. However, due to factors such as plastic screw threads are easy to slip, ceramic screws are brittle and have high processing costs, they are not suitable for mass production.

The invention provides an electrical insulated seat for connecting with a heat radiator and a variable-frequency module of an air-conditioner. The electrical insulated seat comprises a supporting plate and insulated columns; the supporting plate comprises buckles and assembling columns and is assembled on the heat radiator by the matching of the buckles and the clamp holes of the heat radiator; first holes are formed on the assembling columns; the insulated columns are located in preformed holes of the heat radiator; first holes and third holes are formed on the insulated column; the insulated columns are arranged on the supporting plate by the matching of the second holes and the assembling columns; and the third holes and the first holes are communicated to form penetrating holes. Correspondingly, the invention further provides an air-conditioner. According to the technical scheme, the creepage distance from the variable-frequency module to the heat radiator is increased effectively, so that the requirement of the creepage distance in the international standard is satisfied; the heat radiation speed of the variable-frequency module is improved effectively; in addition, the insulated columns and the supporting plate of the electrical insulated seat are molded, so that the price is low and the cost is reduced.
Description
technical field [0001] The invention relates to the field of household electrical appliances, more specifically, to an electrical insulating seat and an air conditioner. Background technique [0002] Such as figure 1 , figure 2 , image 3 As shown, the frequency conversion module 1 of the existing frequency conversion air conditioner needs to dissipate heat through the radiator 4. In order to ensure the effective contact and insulation between the radiator 4 and the frequency conversion module 1, an insulating rubber heat conduction sheet is usually placed between the radiator 4 and the frequency conversion module 1. The rubber pad 2 ensures the gap between the radiator 4 and the frequency conversion module 1 . However, due to the effective and reliable connection between the frequency conversion module 1 and the radiator 4 , most products currently on the market are connected by metal screws 3 . Since the radiator bolts are connected to the radiator 4, the creepage dis...
