Sealing assembly for electronic component and underwater booster
A sealing assembly for electronic components including a sealing seat and a sealing shell for mounting the electronic component. The sealing shell is received through an opening in the top of the sealing seat and into complementary mounting chamber. A left end of the sealing shell includes a first connection channel; a left end of the mounting chamber includes a second connection channel and a sealing gasket surrounding the second connection channel.
