Fig. 2 is the structural representation (down state) about reed-type press-key structure embodiment in the present invention.
Fig. 3 is the structural representation about control panel embodiment in the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is elaborated.
Refer to Fig. 1 and 2, shown in figure is a kind of reed-type press-key structure, is applicable to the control system that aviation, naval vessel or weapons are equipped, in order to improve the fabrication tolerance between keying body 1 and reed switch 2.This press-key structure forms primarily of keying body 1, reed switch 2 and cap body 3.
Described reed switch 2 is in the below of described keying body 1, is formed with gap between described reed switch 2 and described keying body 1.Described cap body 3 is between described keying body 1 and described reed switch 2.Described cap body 3 combines with described keying body 1 and described cap body 3 and described reed switch 2 offset.Specifically, the bottom surface of described keying body 1 is formed with the auxiliary section to downward-extension.Described auxiliary section has first paragraph and second segment.Wherein, the diameter of described first paragraph is greater than the diameter of described second segment, described first paragraph relative to described second segment more adjacent to the bottom surface of described keying body 1.Described cap body 3 is defined formed by cap body 3 medial surface, cap body 3 lateral surface, the outer end face of cap body 3, cap body 3 inner top surface, cap body 3 bottom surface.Described cap body 3 medial surface coordinates with described second segment, and the bottom surface of described cap body 3 bottom surface and described first paragraph offsets, and the end face of described cap body 3 inner top surface and described second segment has one first gap.Again, the diameter of described cap body 3 medial surface is less than the diameter of described second segment, makes described cap body 3 and described second segment interference fit.In the present embodiment, the diameter of described cap body 3 medial surface is less than the diameter of described second segment, and the diameter of described cap body 3 lateral surface is equal to or less than the diameter of described first paragraph, plays support structure effect.In the present embodiment, the diameter 2mm less of the diameter of described second segment of described cap body 3 medial surface.Again again, described first clearance control is at 0.2-0.6mm.In the present embodiment, gap value is 0.4mm.Separately again, the outer end face of described cap body 3 and described cap body 3 inner top surface spacing are greater than 1mm, that is, the thickness of described cap body 3, can have different specifications, and concrete numerical value can be determined according to actual conditions.The most again, described keying body 1 is employing hard material, and described cap body 3 is employing elastomeric material.In the present embodiment, hard material is plastics, and elastomeric material is rubber.
Referring to Fig. 3, is the key controlled panel of a kind of light-guiding type shown in figure, is applicable to the equipment control systems such as aviation, naval vessel, weapons.This control panel forms primarily of light guide panel 4, printed circuit board 6, light conductor, base plate 5 and above-mentioned reed-type press-key structure.Wherein, described keying body 1 is arranged in described light guide panel 4, and described reed switch 2 is arranged on described printed circuit board 6.During assembling, put into described light conductor and described printed circuit board 6 successively respectively in described light guide panel 4, described reed switch 2 is fixed on described printed circuit board 6, and described cap body 3 contacts with described reed switch 2.By screw 7, base plate 5 and other structural members are fixed in light guide panel 4.Press described keying body 1, the comfortableness of test button, as button comfort level is mated with preset value, completes assembling process.If handfeel of keys is partially lax, take screw 7 and structural member apart, change cap body 3 described in thick die bed.If handfeel of keys stroke is partially short, change cap body 3 described in thin die bed.
Below only have expressed embodiments of the present invention, it describes comparatively concrete and detailed, but can not therefore be construed as limiting the scope of the patent.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
