Plastic board and keyboard thereof
A plastic board suitable for a keyboard having first and second keyswitch sets includes first and second board portions and transverse dividing slots. The first and second board portions have first and second mounting areas respectively corresponding to the first and second keyswitch sets. First dividing slots of the first board portion extend sequentially along a periphery of at least one first mounting area to separate first and second board regions. Second dividing slots of the second board portion extend sequentially along a periphery of at least one second mounting area to separate third and fourth board regions. The transverse dividing slots are formed separately between the first and second board portions to separate the first and third board regions and separate the second and fourth board regions. The first, second, third, and fourth board regions have a feeding point, respectively, to be formed by an injection molding process.
1 . A keyboard comprising:
at least one first keyswitch set comprising a plurality of first keyswitches arranged along a transverse direction;
at least one second keyswitch set comprising a plurality of second keyswitches arranged along the transverse direction; and
a plastic board connected to the at least one first keyswitch set and the at least one second keyswitch set, the plastic board comprising:
a first board portion having a plurality of first mounting areas corresponding to the plurality of first keyswitches, a plurality of first dividing slots extending sequentially along a periphery of at least one first mounting area within a first middle section of the first board portion to separate a first board region and a second board region on the first board portion;
a second board portion having a plurality of second mounting areas corresponding to the plurality of second keyswitches, a plurality of second dividing slots extending sequentially along a periphery of at least one second mounting area within a second middle section of the second board portion to separate a third board region and a fourth board region on the second board portion; and
a plurality of transverse dividing slots formed separately between the first board portion and the second board portion to separate the first board region and the third board region and separate the second board region and the fourth board region;
wherein the first board region, the second board region, the third board region, and the fourth board region have at least one feeding point, respectively, to be formed by an injection molding process.
2 . The keyboard of claim 1 , wherein at least one of the first board region and the third board region forms a stop slot at a position corresponding to a bridge section of any two adjacent transverse dividing slots.
3 . The keyboard of claim 1 , wherein at least one of the first board region and the second board region forms a stop slot at a position corresponding to a bridge section of any two adjacent first dividing slots.
4 . The keyboard of claim 1 , wherein a plurality of hook arms is integrally formed at a position on the plastic board corresponding to the plurality of first mounting areas and extends downward to be engaged with a holding board of a computer device, to make the keyboard detachably mounted on the computer device.
5 . The keyboard of claim 4 , wherein the plastic board has a hole corresponding to the hook arm, and a rib is suspended in the hole and connected to the hook arm.
