Description

Technical Field

[0001] The utility model relates to the technical field of connectors, specifically a male connector, a female connector and a connector assembly for noise reduction. Background Technology

[0002] A split air conditioner consists of an indoor unit and an outdoor unit. The system joint for connecting the refrigerant medium between the two units uses a stop valve as the joint in the existing technology. It has the following disadvantages: First, it requires professional installation, which is labor-intensive and time-consuming. Especially in Europe and the United States, labor costs are expensive, and the installation cost is often higher than the cost of the air conditioner itself; second, a small amount of refrigerant will leak during the connection operation; third, air may sometimes enter the refrigeration system during installation, causing the pressure of the refrigeration system to increase when it is working, and the refrigeration performance will deteriorate.

[0003] The existing split connector is divided into a male connector and a female connector. When the fluid passes through the male connector and the female connector, it will hit the spring, resulting in a large noise. At the same time, the valve body sealing structure uses O-rings for sealing, resulting in poor sealing and short service life. The structure of the female connector makes the assembly process complicated, which invisibly increases the production cost. Contents of utility model
