Advantage of the present invention is, because adopting the single U-shaped support with direct inserted type is its support component, cooperate keycap bottom pillar to form firm the combination, thereby can reduce the operation noise of strip button, make the vertical stretching motion of keycap more smooth with positioning seat on the keyboard substrate; In addition, owing to adopt the U-shaped support design of direct inserted type, the operation of the spare part that need not fix when the assembling keycap makes the easy to assembly quick of strip keycap.
Below cooperate referring to accompanying drawing, describe assembly, structure and the effect of the present invention's one specific embodiment in detail.
Fig. 1 is an assembly exploded view of the present invention.
Fig. 2 is the transverse sectional view of the present invention after combination.
Fig. 3 is a side view cutaway drawing of the present invention, shows that keycap is not depressed.
Fig. 4 is a side view cutaway drawing of the present invention, shows that keycap is depressed.
As shown in Figure 1, the computor-keyboard pushbotton of low noise of the present invention comprises that the bottom of the strip keycap 15 on keyboard substrate 10 is provided with keyseat 11, two draw-in grooves 12 and 13, two positioning seats 20 and 21, with the U-shaped support 14 of a direct inserted type.
This strip keycap 15 comprises, is provided with the projection 16 that one protrudes out downwards in the middle of its root edge face, and is respectively equipped with the pillar 17 and 18 that one protrudes out downwards in its root edge face two side ends.In addition, the lateral border in this two pillar 17 and 18 is respectively equipped with embeded slot 19 (embeded slot of Fig. 1 B-C post 18 lateral borders does not show).
Above-mentioned two embeded slots 19 are same configuration, the characteristics of each embeded slot 19 are: the female parts of groove has broader forward and backward openend respectively, and make the two corresponding tapers that become less spacing in the middle of the groove, embeded slot 19 bottoms are protruded the position and are then formed the inclined-plane downwards, therefore, U-shaped support 14 two ends bending segment ends are fastened to inside grooves easily along this inclined-plane, embeded slot 19 bottom.
And for example among Fig. 1, be located at the keyseat 11 on the keyboard substrate 10, the projection 16 that its openend just protrudes out corresponding to keycap 15 root edges, the hollow inside of keyseat 11 is provided with elastic insulated rubber blanket (rubber blanket is not represented among Fig. 1).When pressing down keycap 15, keyseat 11 openends can be for projection 16 at keyseat 11 inner stretching motions, or by the elasticity of rubber blanket with keycap 15 pop into position.Two positioning seats 20 and 21 on the keyboard substrate 10 lay respectively on the pillar 17 and 18 pairing positions of keycap 15 root edge both sides, and two positioning seats 20 are identical with 21 structure, are the U font of opening laterally.When pressing down keycap 15, each positioning seat 20 just can be for corresponding each pillar 17 and 18 vertical within it stretching motions with 21.Two draw-in grooves 12 and 13 are located at respectively on the substrate 10 in aforementioned each positioning seat 20 and 21 outsides, and two draw-in grooves 12 are identical with 13 structure, and the openend of draw-in groove upwards in just can being snapped into for the traversing section of U-shaped support 14, forms tight clamping.
