An information device comprising:
- a control board having a circuit unit and a retaining portion;
- a shell sleeved onto said control board and having an end contacting against said retaining portion;
- and
- a sealing cap sleeved onto the other end of said shell and being engaged with said control board, thereby relatively securing said sealing cap and said control board in position and confining said shell between said retaining portion and said sealing cap;
- wherein said control board comprises a coupling end having two decreasingly narrowing opposite sides, said coupling end having two recesses on the two opposite sides of said control board;
- said sealing cap comprises a plate-like stopping portion and a clamping portion, said clamping portion having two claw hooks extending parallel from two ends of a side of said stopping portion, each of said claw hooks having a ditch and a fending portion, said ditch having substantially the same width as the thickness of said electronic circuit board at its inner side, said fending portion protruding from a free end of one of said claw hooks for jamming said recess and further securely engaging said sealing cap and said control board while said clamping portion is inserted into said shell and then said coupling end of said electronic circuit board slides into said ditches.
