Button

Technical field

The present invention relates to a kind of button, particularly a kind of button with hook structure.

Background technology

Button has been widely used in the electronic product as switch, can be referring to people such as Slobodan Krstic at document IEEETransactions on components, Hybrids, Push-ButtonHybrid Switch one literary composition among the and Manufacturing Technology.

Fig. 1, front view and the left view that is respectively a kind of common button 10 shown in Figure 2.This button 10 generally includes press section 11, and these 11 back sides, press section protrude out a guide pillar 12 backward, and this guide pillar 12 extends back several grabs 13 away from an end of press section 11.Common push button panel (figure does not show) generally includes the block button hole that can match with described grab 13, and when this button 10 was gone into push button panel by group, grab 13 can be pressed into the block button hole on the push button panel, thereby is held.

Yet described several grabs 13 are vertically extended back by described guide pillar 12 usually and form, and when button 10 was pressed, the stress that the bottom 130 of grab 13 is subjected to was comparatively concentrated, thereby cause grab 13 fractures easily, and then make the useful life of button 10 shorter.

Summary of the invention

To a kind of compressive resistance height, the button of easy fracture not be described with specific embodiment below.

A kind of button, it comprises a press section, one annular guide column and at least one grab, this press section comprises a press surface and a composition surface relative with this press surface, this annular guide column has first end and reaches and this first end opposite second end, this first end links to each other with described composition surface, this at least one grab is arranged on the end face of the second end of described annular guide column, this at least one grab comprises a main part and a clamping part respectively, this main part links to each other with the end face of the second end of described annular guide column, and the junction of this main part and annular guide column is formed with chamfering, the inboard of this main part is provided with a ribs, and this ribs links to each other along the axial direction extension of described annular guide column and with the inwall of described annular guide column.

Compared with prior art, the main part of the grab of described button and the junction of annular guide column are formed with chamfering, the inboard of this main part is provided with ribs and this ribs links to each other with the inwall of annular guide column, this kind structure can be disperseed the stress that grab bore when button is pressed, thereby can improve the compressive resistance of grab, make button have the advantage of long service life.

Embodiment

Below in conjunction with accompanying drawing the embodiment of the invention is described in further detail.

Referring to Fig. 3 and Fig. 4, the button 20 that the embodiment of the invention provided comprises press section 22, guide pillar 24 and grab 26.

Described press section 22 comprises press surface 220 and the composition surface 222 relative with this press surface 220.

Described guide pillar 24 is arranged on the composition surface 222 of described press section 22, its have first end 240 and with these first end 240 opposite second end 242.This first end 240 links to each other with the composition surface 222 of described press section 22.Certainly, this guide pillar 24 also can be integrated with press section 22, thereby this guide pillar 24 can be protruded out along the direction away from press section 22 by the composition surface 222 of described press section 22 and forms.This guide pillar 24 is an annular guide column, and its inside can be formed with the through hole that runs through first, second end 240,242, or the blind hole that sets to the concave from the second end 242.In the present embodiment, this guide pillar 24 is the inner annular guide column that is formed with the through hole that runs through first, second end 240,242.

Described grab 26 is arranged on the end face of the second end 242 of described guide pillar 24.This grab 26 comprises a main part 260 and a clamping part 262.This main part 260 links to each other with the end face of the second end 242 of described guide pillar 24, and the junction of this main part 260 and guide pillar 24 is provided with chamfering, thereby the width d of this junction diminishes gradually along the direction away from guide pillar 24.Preferably, this chamfering is the R angle.The inboard of this main part 260 is provided with ribs 264, and this ribs 264 links to each other along the axial direction extension of described guide pillar 24 and with the inwall of described guide pillar 24.Certainly, this grab 26 can be integrated with described guide pillar 24, and this grab 26 can be formed along extending away from the direction of guide pillar 24 by the second end 242 ends of guide pillar 24.

Referring to Fig. 5, also rib 224 can be set on the described press section 22, this rib 224 can be integrated with press section 22, it is formed at the composition surface 222 of press section 22 and links to each other with the lateral wall of the first end 240 of described guide pillar 24, thereby can improve the compressive resistance of guide pillar 24 and the junction of press section 22.Preferably, this rib 224 is an axis with the central shaft of described guide pillar 24, be distributed in the lateral wall of guide pillar 24 first ends 240 radially along 24 circumferencial directions of guide pillar around.

The button 20 that the embodiment of the invention provides, the main part 260 of its grab 26 is formed with chamfering with the junction of guide pillar 24, the inboard of this main part 260 is provided with ribs 264 and this ribs 264 links to each other with the inwall of guide pillar 24, the stress that this kind structure can disperse grab 26 to be born when button 20 is pressed, thereby can improve the compressive resistance of grab 26, make button 20 have the advantage of long service life.

In addition, those skilled in the art also can do other and change in spirit of the present invention, as the quantity of the structure of suitable change guide pillar, grab or structure and contiguous block position etc. is set, as long as it does not depart from technique effect of the present invention and all can.The variation that these are done according to spirit of the present invention all should be included within the present invention's scope required for protection.
