Embodiment

Below in conjunction with Figure of description embodiment of the present utility model is done detailed description.

Please also refer to Fig. 1 to Fig. 7, the keyboard package assembly 1 that preferred embodiment of the present utility model provides comprises a base plate 2, a film circuit board 3, a space bar 4, a rubber mat plate 5, a button deckle board 6, some bridge formations 7 and some keycaps 8.

Base plate 2 can be waterproof material, and film circuit board 3 is arranged on base plate 2 tops, and have a circuit layout 31 and some trip points 32, each trip point 32 is correspondingly to be arranged on a keycap 8 belows, and film circuit board 3 is at the different signal of the matrix position of each keycap 8 transmission corresponding with function.

Space bar 4 can be aluminium matter or plastic material, it is arranged on film circuit board 3 tops, and space bar 4 corresponding single keycaps 8 places have two holding grooves 41 and two guide runners 42, and be provided with the through hole 43 of corresponding quantity in the position of space bar 4 corresponding trip points 32, for penetrating of the elastic component 51 of rubber mat plate 5 by compression leg 511.

Rubber mat plate 5 is arranged on space bar 4 tops, and has a plurality of elastic part 51, and each elastic component 51 is a corresponding keycap 8 belows that are arranged on, and each trip point 32 of each elastic component 51 more corresponding film circuit board 3 is provided with, and single keycap 8 times, two holding grooves 41 of rubber mat plate 5 corresponding space bars 4 and the position of two guide runners 42 are provided with corresponding open-work 52, penetrate for corresponding holding groove 41 and guide runner 42; In addition, have one in the elastic component 51 by compression leg 511, it is made by conductive material to press compression leg 511.

Button deckle board 6 is arranged on rubber mat plate 5 tops, and each is built bridge and 7 is arranged between rubber mat plate 5 and the button deckle board 6, and each keycap 8 is arranged on button deckle board 6 tops; Each keycap 8 is roughly rectangular, but not as limit, keycap 8 has a roof 81 and a ring-side wall 82, ring-side wall 82 is to be connected with the periphery of roof 81, and ring-side wall 82 is internally oblique surface construction (as shown in Figure 3), and and roof 81 folder one acute angle (being that arbitrary of ring-side wall 82 angle between the face with roof 81 places is the acute angle of spending less than 90); Accordingly, button deckle board 6 is the hollow frames 61 with corresponding keycap 8 quantity, and the inner peripheral of each framework 61 is constructed corresponding formation one inclined-plane 611 with the interior inclined-plane of the ring-side wall 82 of each keycap 8.Because keycap 8 internally oblique surface constructions, therefore the interval (as Fig. 4 and shown in Figure 7) between each contiguous keycap 8 is less than the contiguous keycap interval of existing vertical plane structure or outer inclined-plane structure, and roof 81 areas of the keycap 8 of interior inclined-plane structure, it is keycap roof area greater than vertical plane structure or outer inclined-plane structure, the importing of wisps such as dust can be avoided, and the keyboard figure of other function or the employed salient point of blind person etc. can be on bigger roof 81 areas, added.

In addition, one side surface of the roof 81 contiguous bridge formations 7 of keycap 8, be to have two articulated parts 83, two interlocking part 84 and pillars 85, the both sides of bridge formation 7 are to have carrier 71 and slide-bar 72 respectively, and guide sliding part 73 and

pivot

74, and 7 the center of building bridge is equipped with a perforation 75, carrier 71 is to be articulated in rotationally in the articulated part 83, slide-bar 72 is to be arranged on rotationally in the holding groove 41, guide sliding part 73 is to be embedded rotationally in interlocking part 84, and pivot 74 is to be arranged on rotationally in the guide runner 42; And the bottom of pillar 85 is to pass perforation 75 and support to end top at elastic component 51.
