A keyboard comprises a key module and a backlight module in which the key module comprises a light-transmissive key part and an electric circuit substrate, and the backlight module comprises a light guide plate, a reflection unit and at least one light source. The backlight module is disposed between the key part and the electric circuit substrate. Thus, lights emitted by the light source are projected into the light guide plate from the lateral side of the light guide plate, and the lights are reflected by the reflection unit for directly passing through the light output surface of the light guide plate and the key part.

An adapter (100) includes a printed circuit board (9), a first connector mounted onto the printed circuit board and having a room, a second connector mounted onto the printed circuit board and having a chamber (62), and an optical device (8) including a first optical module (81) and a second optical module (82) optically connecting with each other. The first connector includes a tongue portion (11) extending into the room and a set of terminals (212, 222) having contacting portions (2120, 2220) disposed on one side of the tongue portion and exposed to the room. The first optical module is disposed on another side of the tongue portion (11) opposite to the contacting portions. The second connector includes a set of contacts (66) having contacting sections (661) exposed to the chamber. The second optical module is disposed on the second connector and communicates with the chamber (62).
