The connector assembly includes a housing (11) in which a contact terminal (13A) and an earth terminal are insert-moulded. Inner and outer surfaces of an annular sealing member (14) respectively engage a connection groove (111) extending around the housing (11) and confronting airtight protrusion parts (4) of the upper and lower casings (100A, 100B). The mobile phone casing may comprise a casing body with a connector assembly insertion hole in a sidewall thereof and a cover. The connector assembly and a printed circuit board (2) are secured to the mobile phone casing such that the contact terminal (13A) and the earth terminal engage connection terminals (21A) of a printed circuit board connector (21) or traces on the printed circuit board. A method of assembling a mobile phone is also disclosed.
