In the utility model embodiment, keyboard switch comprises: upper cover 101, pressing piece 102, spring 103, base 104, fixed contact 105 and moving contact 106; Be provided with hollow cylinder in base 104, on the sheathed hollow cylinder being arranged on base 104 of spring 103, pressing piece 102 passes upper cover 101 and is arranged on base 104 together with upper cover 101.
Moving contact 106 to be arranged on base 104 and the welding foot of moving contact 106 through base 104, wherein fixed contact 105 to be arranged on base 104 and the welding foot of fixed contact 105 through base 104, and moving contact 106 and fixed contact 105 present relative position arranges;
Wherein, one end of spring 103 contacts with base 104, and the other end of spring 103 contacts with pressing piece 102, and upper cover 101 arranges through hole, and pressing piece 102 is through the through hole of upper cover 101, and upper cover 101 is combined by the mode of clamping and base 104;
Wherein, moving contact 106 is arranged the first contact-making surface 1061, and the second contact-making surface 1062 of arch is set in the both sides of the first contact-making surface 1061.
Wherein, the 3rd contact-making surface 1051 that fixed contact 105 is arranged arranges two convex tendons 1052, fixed contact 105 is contacted with the first contact-making surface 1061 by any one on the 3rd contact-making surface 1051 or two convex tendons 1052 and forms closed primary importance;
Wherein, pressing piece 102 is arranged the inclined-plane 1021 for extruding the second contact-making surface 1062, when pressing piece 102 down moves, inclined-plane 1021 the second contact-making surface 1062 extruded on moving contact 106 impels the convex tendon 1052 on the 3rd contact-making surface 1051 to be separated with the first contact-making surface 1061 second place being formed and disconnect.
It should be noted that, the number of the convex tendon 1052 that the 3rd contact-making surface 1051 of fixed contact 105 is arranged can be at least two, such as, it can be two, three or four, and the convex tendon 1052 that the 3rd contact-making surface 1051 is arranged can be parallel may also be nonparallel, and in actual applications, number and the position of convex tendon 1052 on the 3rd contact-making surface 1051 can be set according to concrete demand.Wherein, if convex tendon 1052 is for be arrangeding in parallel, then effectively can improve the stability that convex tendon 1052 contacts with the first contact-making surface 1061, fixed contact 105 and moving contact 106 all can not offset.
In the utility model embodiment, can go out convex tendon 1052 by the mode of punching press on the 3rd contact-making surface 1051, processing technology is simple.
It should be noted that, in a first embodiment, only to arrange convex tendon 1052 to describe the structure of the utility model keyboard switch on the 3rd contact-making surface 1051, except convex tendon 1052 can be arranged on the 3rd contact-making surface 1051, at least two salient points or boss can also be set, what also effectively can increase the 3rd contact-making surface 1051 and the first contact-making surface 1061 can contact range, improves the useful life of keyboard switch.
It should be noted that, the first contact-making surface 1061 on moving contact 106 is also arch, and the height of the arch of the first contact-making surface 1061 is lower than the height of the arch of the second contact-making surface 1062.
In the utility model, the material of the first contact-making surface 1061, second contact-making surface 1062 and the 3rd contact-making surface 1051 is copper, or the surface of the first contact-making surface 1061, second contact-making surface 1062 and the 3rd contact-making surface 1051 is layers of copper.
In the utility model, base 104 arranges hollow cylinder, one end that spring 103 overlaps is enclosed within the periphery of the hollow cylinder of base 104 and contacts with base 104; Pressing piece 102 arranges the first cylinder, and the periphery that the other end of spring 103 is enclosed within the first cylinder contacts with pressing piece 102, and the internal diameter of hollow cylinder is greater than the external diameter of the first cylinder, and when primary importance, a part for the first cylinder is in the cavity of hollow cylinder.
In the utility model, the relative both sides of pressing piece 102 arrange vertical outstanding slideway, and base 104 are arranged the groove of coupling slideway, the slideway of pressing piece 102 can be stuck in groove and move up and down.
In the utility model, when keyboard switch is in unused state, the convex tendon 1052 on the 3rd contact-making surface 1051 of fixed contact 105 contacts with the first contact-making surface 1061 of moving contact 106 and forms closure state, is primary importance.If apply power down on pressing piece 102, pressing piece 102 down moves, and pressing piece 102 be along base 104 arrange groove down move, and the inclined-plane 1021 that pressing piece 102 is arranged is by moving contact second contact-making surface 1062 along with pressing piece 102, and extruding is formed to the second contact-making surface 1062, because moving contact 106 has elasticity, make the extruding of inclined-plane 1021 to the second contact-making surface 1062 impel the first contact-making surface 1061 of moving contact 106 to depart from convex tendon 1052 on the 3rd contact-making surface 1051, be the second place.And there is elasticity due to spring 103, when pressing piece 102 down moves, spring 103 is produced elastic force by compression, when the power that pressing piece 102 applies is cancelled, pressing piece 102 up moves under the effect of the elastic force of spring 103, and make inclined-plane 1021 depart from the second contact-making surface 1062 gradually, moving contact 106 returns to original position under the elastic force effect of himself, and the first contact-making surface 1061 contacts with the convex tendon 1052 on the 3rd contact-making surface 1051, namely returns to primary importance.
In the utility model, 3rd contact-making surface 1051 of fixed contact 105 is arranged at least two convex tendons 1052 or salient point or boss, and fixed contact 105 is contacted with the first contact-making surface 1061 by any one or more convex tendons 1052, salient point or the boss on the 3rd contact-making surface 1051, make the first contact-making surface 1061 and the 3rd contact-making surface 1051 can contact-making surface larger, effectively can improve the useful life of keyboard switch.And due to just expression the first contact-making surface 1061 and the 3rd contact-making surface 1051 conducting after touching any one convex tendon 1052, salient point or boss of the first contact-making surface 1061, therefore, it is possible to the effective response speed improving keyboard switch.
In the utility model, moving contact 106 arranges the second contact-making surface 1062 respectively in the both sides of the first contact-making surface 1061, and the inclined-plane 1021 corresponding with the second contact-making surface 1062 is set on pressing piece 102, pressing piece 102 is when pressing, second contact-making surface 1062 of the first contact-making surface 1061 both sides will be extruded simultaneously, therefore, it is possible to the effective balance keeping moving contact 106, and moving contact 106 and fixed contact 105 all can not offset, effectively can improve the useful life of moving contact 106, and the useful life of keyboard switch can be improved.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be do not depart from technical solutions of the utility model content, according to any simple modification that technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
