After the production of the terminal block is completed, the terminal block is placed on the airtight detection seat 2. The lower pressure seat 7 is controlled to move downward by the lower pressure cylinder 5 and pressed tightly on the terminal block. At this time, the terminal block is clamped on the airtight detection seat 2. After applying a certain pressure through the air pressure detector, the pressurization is stopped. The speed of air pressure decay is observed through the air pressure detector 8. When the sealing of the terminal block is good, the air pressure decay speed is small. When the sealing of the terminal block is not good, the air pressure decay speed is large. The air pressure decay speed can be used to know whether the terminal block is qualified.

The air pressure detector 8 increases the pressure in the airtight card slot 23 to a certain value through the air supply pipe 9 and then stops increasing the air pressure. At this time, the air pressure decay speed is observed on the air pressure detector 8 to judge the airtight effect of the terminal;

[0022] There is a positive pressure between the wiring terminal and the airtight slot 23 , which makes it easier to remove the wiring terminal from the airtight slot 23 .
