On face, sealing cover is fastened at the upper end opening of installation cavity, and the upper port contact position of sealing cover and installation cavity is marked with circumferential direction
The plastic packaging glue-line of distribution sets Packed cavity between the lower surface and PCBA control circuit board of sealing cover, wherein sealing cover
Lower surface is fixed with the support column being arranged downwards, and support column is close to setting with the inner bottom surface of installation cavity, at this time support column
Improve the installation strength of sealing cover.
As further program of the utility model：The sealing cover is made of plastic material.
As further program of the utility model：It is in integral structure between the sealing cover and support column.
As further program of the utility model：It offers in the PCBA control circuit board and is passed through for support column activity
Jack.
The beneficial effects of the utility model：The utility model relative to traditional structure essentially consist in PCBA control circuit board with
Cavity is equipped between sealing cover, it can be PCBA control circuit board that cavity, which can reserve heat-dissipating space for PCBA control circuit board,
Reserved thermal expansion stress Free up Memory, while the usage amount of less plastic packaging glue reduce cost, and fast, the work that plastic packaging glue is dry
Make high-efficient.
The additional aspect and advantage of the utility model will be set forth in part in the description, partially will be from following description
In become obvious, or recognized by the practice of the utility model.
