Structure for covering interconnection of a folding electronic device

A structure for covering an interconnection sheet of a folding electronic device, comprising:

• a main body including a flat cavity and a window opening at the back end thereof;
• a cover member including a flat cavity coupled rotatably at the back end thereof to the back end of said main body;
• the interconnection sheet disposed through said window opening from an internal cavity of said main body to said flat cavity of said cover member;
• and
• a cover unit protecting said interconnection sheet in the proximity of the back end of said main body;
• said cover unit including:
• a base plate fixed in the proximity of the back end of said internal cavity of said main body;
• a cover plate attached slidably at the back end of said base plate;
• and
• elastic biasing means fixed between said cover plate and said base plate for biasing said cover plate elastically away from said window opening;
• wherein the back end of said cover member includes a guide edge movable into and out of said window opening according to the rotation of said cover member,
• wherein said cover plate abuts against said guide edge of said cover member by bias of said elastic biasing means to cover any gap between said guide edge and said cover plate.
