Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details:
The mechanical keyboard switch with dust reduction capability as shown in Figures 1 to 5, comprise chassis 1 and be set in turn in described the One On The Chassis upper cover 2, axle core 3, activity external member 4, spring 5, static terminal 6 and moving contacting plate 7 from top to bottom, described spring 5 is sleeved on outside described axle core 3, described axle core 3 comprises the seal convexity 33 being arranged at axle core print 31 on the upside of described axle core 3, arranging the mandrel 32 on the downside of axle core print 31 and be arranged at outside described axle core print 31, and described seal convexity 33 is arranged around described axle core print 31 surrounding.Shown spring 5 is sleeved on outside shown axle core 3, and upper end contacts with the lower surface of axle core print 31, lower end contacts with the upper surface on chassis 1, when pressing the keycap on keyboard as user, spring 5 compresses, now axle core print 31 moves down and enters inside, chassis 1, and drive activity external member 4 to move the described moving contacting plate 7 of shake-up, described moving contacting plate 7 is made to touch on static terminal 6, complete the operation of input, when user stops pressing the keycap on keyboard, spring 5 can be with moving axis core print 31 that keycap is set back, wait for pressing next time, when axle core 3 moves up and down, have dust and other impurities and move into mechanical keyboard inside by axle core 3, therefore, need to install seal convexity 33 additional on axle core print 31, and make seal convexity 33 can fill gap between axle core print 31 and upper cover completely, even can with form non-gap between described upper cover and coordinate, when dust drops on axle core 3, although axle core 3 can be followed to be moved up and down, but because coordinating between seal convexity 33 with upper cover, mechanical keyboard switch internal cannot be entered into, can be removed very easily.
Described seal convexity 33 is one-body molded with described axle core print 31.The bulk strength of axle core 3 can be met, also can meet the interference fit between seal convexity 33 and upper cover 2, effectively prevent seal convexity 33 to be separated from axle core print 31 because of problems such as frictions, cause body construction to the destruction of mechanical keyboard switch.
The thickness of described seal convexity 33 is not less than the gap width between described upper cover 2 and described axle core 3.Meet seal convexity 33 and upper cover 2 carries out non-gap cooperation, but thickness is unsuitable excessive, preferred scope is for being greater than between upper cover 2 and axle center between width 0.01mm-0.1mm.
Described activity external member 4 is provided with detent 41, described seal convexity 33 is provided with the positioning convex 331 coordinated with described detent 41.
Described positioning convex 331 is arranged at the outer middle side part of described seal convexity 33.
The height of described seal convexity 33 equals the height of described upper cover 2 and described axle core 3 cooperation place.
Described axle core print 31 is rectangular structure, through hole 21 is provided with in the middle part of described upper cover 2, and the frontal projected area of described through hole 21 is less than or equal to the frontal projected area of described axle core print 31, the outermost of the orthographic projection view of described axle core print 31 is the projection of seal convexity 33, and namely seal convexity 33 can carry out non-gap with the madial wall of described through hole 21 and coordinates.And axle core print 31 is set to rectangular structure, the complete filling vias 21 of axle core print can be made, increase overall sealing.
Described axle core print 31 offers the card interface 311 for installing keycap, the degree of depth of described card interface 311 is less than the height of described axle core print 31.Card interface 311 is offered downwards by the top of axle core print 31, and is not more than the height of axle core print 31.
Be provided with protruding 41, described protruding 41 in the middle part of described activity external member 4 to be slidably matched with described moving contacting plate 7 towards described moving contacting plate side.The contact area between described moving contacting plate can be reduced, and then the friction reduced between described moving contacting plate 7, increase the useful life of described mechanical keyboard switch, wherein, protruding 41 is one-body molded with described activity external member 4, and be formed with the circular arc of the center of circle outside described activity external member 4 on the downside of in the of described protruding 41, can described protruding 41 most advanced be worn after, continue use.
The mechanical keyboard switch of what the application provided have dust reduction capability, by axle core print 31 and on cover between seal convexity 33 is set, effectively dust etc. can be affected the object gear of mechanical keyboard use in the outside of keyboard, user can be allowed well to eliminate or wiping is gone out, structure is simple, easy to use.
The above; be only preferred embodiment of the present invention; not in order to limit the present invention, every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalently replace and improve, within the protection range that all should be included in technical solution of the present invention.
