Description

The button conducting structure

Technical field

The utility model provides a kind of button conducting structure, refers to a kind of structure that increases button conducting effect especially.

Background technology

At present, like Fig. 1 and shown in Figure 2, be present general employed button conducting structure 1; Mainly form, wherein in main support 11 and time support 12, be provided with an elastic component 13, on it and be provided with a button 14 by a main support 11 and 12 on a support; Being located at 15 last times of keyboard base when button conducting structure 1, mainly is through elastic component 13 button 14 to be pushed against in a level altitude, and just the user does not have under the situation that presses button 14; And after the user pressed button 14, button 14 was conflicted and compression elastic piece 13 simultaneously, made elastic component 13 inner set electrical contacts 131 touch the electrical contact point 151 on the keyboard base 15; Whereby to reach control and the purpose of operating, still, because electrical contact 131 is positioned at the middle position of button 14; What therefore the user must be certain when pressing button 14 presses in the tram; Just can make electrical contact 131 touch the electrical contact point 151 on the keyboard base 15,, perhaps press the strength deficiency if press avris at keyboard base 15; Then possibly cause the action that to control and to operate because of electrical contact 131 can't touch electrical contact point 151; Moreover elastic component 13 can produce the situation of elastic fatigue after long-time the use, also possibly cause the good situation of conducting to take place.　　

The utility model content

In view of this, the technical problem that the utility model will solve is to provide a kind of button conducting structure, makes button under the situation that presses of external force, through the multiple spot contact that these electrical contacts produced, to reach the purpose that increases the conducting effect.

For solving the problems of the technologies described above, the technical scheme of the utility model is achieved in that a kind of button conducting structure, and it includes: a main support wherein is provided with a perforation; A support is arranged at the main support outside; Plural number is contact electrically, is arranged at time support two respective side; One elastic component is arranged in the perforation of main support; One button is arranged on main support and time support; It mainly is on two respective side of inferior support, respectively to be provided with electrical contact, makes button under the situation that presses through external force, and electrically contact produces the multiple spot contact.

Further, inferior support is arranged at the main support outside, and is movable.

Further, main support mainly is to be installed on the keyboard base with time support, and keyboard base is provided with the electrical contact point corresponding to electrical contact.

Further, the electrical contact of plural number can be arranged at two respective side of main support in addition.

The technique effect that the utility model reaches is following: the utility model mainly is made up of a main support, support, the electrical contact of plural number, an elastic component and a button; Wherein on inferior support two respective side, respectively be provided with electrical contact; Make button under the situation that presses of external force; Through the multiple spot contact that these electrical contacts produced, to reach the purpose that increases the conducting effect.

Embodiment

See also Fig. 3, Fig. 4, Fig. 5, Fig. 6 and shown in Figure 7, be stereo appearance figure, three-dimensional exploded view and the preferred embodiment figure of the utility model, find out that by knowing among the figure button conducting structure 2 includes: a main support 3 wherein is provided with a perforation 30; A support 4 is arranged at main support 3 outsides, and is mobilizable state; Plural number is contact 5 electrically, is arranged at time 4 liang of respective side of support; One elastic component 6 is arranged in 3 liang of perforation 30 of main support; One button 7 is arranged on main support 3 and time support 4; Button conducting structure 2 mainly is to be arranged on the keyboard base 8, when button 7 does not receive the pressure that external force presses, through elastic component 6 it is pushed against in a level altitude exactly; Make between button 7 and the keyboard base 8 to have certain distance, just the user does not have and presses under the normal condition of using button 7, and presses after button 7 operates and control when user's application of force; Button 7 is conflicted and compression elastic piece 6; Force main support 3 and time support 4 movable simultaneously downwards, at this moment, the electrical contact 5 on 4 liang of respective side of inferior support touches the electrical contact point 81 on the keyboard base 8; Cause the state of conducting, whereby action operating and control.

Wherein, the position of set electrical contact point 81 on the keyboard base 8 must make time support 4 when activity downwards corresponding to the electrical contact 5 on the inferior support 4, and electrically contact 5 can touch electrical contact point 81 smoothly, with the correct purpose that reaches conducting.

Traditional in the past employed button conducting structure mainly is after pressing button 7, conflicts and compression elastic piece 6 through button 7; Make electrical contact 61 set in the elastic component 6 touch the electrical contact point 81 on the keyboard base 8, reaching the purpose of conducting, and the button conducting structure 2 of the utility model is except still can carrying out the conducting through electrical contact 61 set in the elastic component 6; Simultaneously also can carry out conducting through the electrical contact 5 on 4 liang of respective side of inferior support; Therefore, under situation, when the user presses button 7 with multiple spot contact; Do not need the correct central part that presses button 7; Even press the avris of button 7, also can effectively reach the purpose of conducting through the electrical contact 5 electrical contact points 81 of contact, moreover; Also because button conducting structure 2 can carry out conducting through the electrical contact 5 on 4 liang of respective side of inferior support; Therefore also can exempt originally set electrical contact 61 in the elastic component 6, this moment, the function of elastic component 6 was to be used for pushing against button 7 only just, and it is returned back on the normal position when external world presses not receiving.

And since button 7 behind the pressure that is pressed; Main support 3 all can be movable downwards with time support 4, and therefore, electrically contact 5 is except can being arranged at time support 4; Also can be arranged on two respective side of main support 3; But the position of set electrical contact point 81 then must be different on the keyboard base 8, need be positioned at the position corresponding to the electrical contact 5 on the main support 3, can reach the conducting purpose smoothly.

What deserves to be mentioned is in addition; Because traditional employed button conducting structure only carries out conducting through electrical contact 61 set in the elastic component 6; If elastic component 6 then can cause the awkward situation of conducting smoothly in the long-time situation of using the back to produce elastic fatigue or distortion, review the button conducting structure 2 of the utility model; Even elastic component 6 produces the situation of elastic fatigue or distortion, still can carry out conducting through the electrical contact 5 on 4 liang of respective side of inferior support.

The above is merely the preferred embodiment of the utility model, is not the protection range that is used to limit the utility model.
