Patent ID: 7108518

Claim:
An assembly structure of an electrical card, comprising: a connector frame, having multiple contact terminals at its rear side with the tail ends of said contact terminals electrically connected with electric contacts at the front end of a circuit board, wherein two clamp arms separately protrude from two lateral sides of said connector frame; a back cover, having two extension arms separately extending from two lateral sides thereof; and a shell, further comprising an upper shell and a lower shell, which can be press-fit together to form a unitary body that encapsulates said circuit board, wherein at least one front press-fit platelet is formed on each lateral side in the end of said upper shell to be installed to said connector frame, and said lower shell has at least one press-fit hook at the positions corresponding to said front press-fit platelets; said press-fit hooks of said lower shell are inserted between said connector frame and said clamp arms, and press-fit with said front press-fit platelets of said upper shell to install both said upper shell and said lower shell to said two clamp arms; the other ends of said upper shell and said lower shell are press-fit to said back cover and wrap said two extension arms to assemble said upper shell, said lower shell, said connector frame and said back cover into an electrical card structure; wherein said front press-fit platelet of said upper shell has a through-hole, and said press-fit hook of said lower shell has an inward bent platelet, and said bent platelet is to be press-fit into said through-hole of said front press-fit platelet to engage said front press-fit platelet of said upper shell with said press-fit hook of said lower shell.
