DETAILED DESCRIPTION
Referring to FIGS. 1-2, a foldable computing device 1 is illustrated. In the embodiment, the foldable computing device is a notebook computer. The notebook computer 1 includes a display 10, a base 20, a first connector 30 and a second connector 40. The display 10 is rotatably connected to the base 20. The first connector 30 is electrically connected to the display 10, and the second connector 40 is electrically connected to a circuit board (not shown) of the base 20. The first connector 30 and the second connector 40 are connected together to electrically connect the display 10 to the circuit board of the base 20, such that signals can be transmitted between the display 10 and the base 20.
Referring also to FIGS. 3-4, the display 10 includes an insulating cover 101 having a first arc-shaped end 102. The first arc-shaped end 102 includes an arc-shaped inner surface 103. The inner surface 103 defines a plurality of slots 104 that extend in a circumferential direction and are substantially parallel to each other. Each slot 104 includes a first conductive member 105 (see FIG. 7). In the embodiment, the first conductive member 105 is a metal layer coated on the bottom of each slot 104. Each conductive member 105 is connected to one contact (not shown) of the first connector 30.
Referring also to FIGS. 5-6, the base 20 includes an insulating base plate 201 at bottom. The base plate 201 includes a second arc-shaped end 202. The second arc-shaped end 202 includes an arc-shaped outside surface 203 that including a plurality of protruding ridges 204 spaced from each other. In the embodiment, there are equal numbers of the ridges 204 and the slots 104. Each ridge 204 includes a second conductive member 205 (see FIG. 7). In the embodiment, the second conductive member 205 is a metal layer coated on the ridge 204. Each second conductive member 205 is connected to one contact (not shown) of the second connector 40.
In the embodiment, the notebook computer 1 further includes a protective cover 50 to shield exposed portions of the ridges 204 when the ridges 204 are not received in the slots 104 to prevent the ridges 204 from being damaged. A gap 501 (see FIG. 7) is formed between the protective cover 50 and the second arc-shaped end 202 to receive the first arc-shaped end 102.
Referring to FIGS. 7-8, when the display 10 is rotated to a predetermined position, the arc-shaped end 102 moves into the gap 501 with the ridges 204 received in the slots 104, respectively, causing the conductive members 105 to contact the conductive members 205. The connectors 30 and 40 are thus electrically connected. Rotating the display 10 back to a closed position, causes the conductive members 105 to lose contact with the conductive members 205, thus the connectors 30 and 40 become disconnected.
Referring to FIGS. 9-10, in an alternative embodiment, a notebook computer 1a is substantially the same as the notebook computer 1 except for the following: a plurality of ridges 104a protrude from the inner surface 103 of the cover 101, and a plurality of slots 204a are defined in the outside surface 203 of the base plate 201.
Although the present disclosure has been specifically described on the basis of the exemplary embodiment thereof, the disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiment without departing from the scope and spirit of the disclosure.
