The present invention relates to be used as the structure of push-button switch of the console switch of various electrical equipment, especially relate to the fixed terminal that is arranged in the housing and the structure of armature contact.
Structure as the conventional button switch that is used as console switch, such structure is well-known, promptly on the inner bottom surface of the housing of making box-shaped with insulating material such as synthetic resin, be provided with and expose fixed contact securing and that constitute by conducting metal and be arranged on this fixed contact opposite and dome-shaped armature contact that constitute by metal equally, the projection that utilization is arranged on the core bar that is slidably disposed in the described housing accommodation section is pushed the dome-shaped top of armature contact, thereby makes dome-shaped armature contact that itself and fixed contact are separated.
In addition, with said structure differently, a kind of like this push-button switch structure also is well-known, be that armature contact becomes tabular, central authorities' quilt of the armature contact of this piece flat board is towards formed contact chip protrudingly, be accompanied by the counter-rotating that is configured in the rubber spring in the housing accommodation section, push described contact chip, thereby described contact chip leaves fixed contact by the projection of described rubber spring.In this case, we have also known such armature contact structure, promptly replace above-mentioned armature contact, make the bottom of carbon contact contact rubber spring and have formed described armature contact.
In preceding a kind of traditional structure, along with the switching of switch contact is carried out in the counter-rotating of dome-shaped armature contact, thereby such structure is applicable to the push-button switch that operational stroke is short.On the contrary, in a kind of traditional structure in back, reverse and carry out the switching of switch contact owing to be accompanied by rubber spring, so this structure is applicable to the push-button switch that operational stroke is long.
But, in above-mentioned conventional button construction of switch, under the situation that seeks out the long push-button switch of operational stroke, must set greatlyyer from the bottom surface of described rubber spring to the height at top, when must be bigger, with regard to the problem of overall dimension that forced ground increasing button switch short transverse occurred the rubber spring height setting.
In addition, in the structure of carbon contact contact rubber spring lower end, because the contact resistance increase, so must be used as fixed contact to precious metals such as gold, thereby exist the problem that increases cost.
Thereby, the objective of the invention is to address the above problem and provide a kind of like this operational stroke long push-button switch structure, promptly in the contact resistance that can reduce push contact portion, increasing button switch overall dimension not.
For addressing the above problem, as first technical scheme one push-button switch has been proposed in the present invention, it comprises housing with accommodation section, expose to fixed contact on the inner bottom surface of described accommodation section, have central authorities towards the protruding contact chip that forms and be configured to the armature contact relative, have the rubber spring of described contact chip being pressed to the activation projection of fixed contact direction with described fixed contact, formed the recess that exposes described fixed contact on the central portion of described accommodation section inner bottom surface, described contact chip is the bending downwards by bend in described recess.
Second technical scheme of the present invention has proposed such technical characterictic, be that described armature contact is to be made of the seat portion that takes shape in the outside, the connecting portion that extends from seat portion, the described contact chip that is arranged on swingably in the described seat portion by connecting portion, time bend the described bend that described contact chip forms and take shape on the described contact site.
The 3rd technical scheme of the present invention has proposed such technical characterictic, promptly when constituting described armature contact by the rubber-like sheet metal, has offered the circular arc punching in the central authorities of described seat portion, has formed described contact chip on the central portion of punching.
The 4th technical scheme of the present invention has proposed such technical characterictic, and promptly described rubber spring is arranged in the described seat portion, and described activation projection is pushed described contact chip by the described punching that is arranged on central authorities of described seat portion.
The 5th technical scheme of the present invention has proposed such technical characterictic, and promptly the bend of described contact chip is configured to contact the inner bottom surface of described recess.
The 6th technical scheme of the present invention has proposed such technical characterictic, and promptly the bend of described contact chip is configured to break away from the inner bottom surface of described recess.
As mentioned above, because push-button switch of the present invention is so to form, promptly in the accommodation section inner bottom surface central authorities that are arranged on the housing, formed the recess that exposes fixed contact, the contact chip of armature contact is the bending downwards by bend in recess, so the height of rubber spring does not increase, because the stroke of rubber spring activation projection can only increase at recess, thus the not increase of the overall dimension of push-button switch, thus can provide operational stroke long push-button switch structure.
Because described armature contact is to be made of the seat portion that takes shape in the outside, the connecting portion that extends from seat portion, the described contact chip that is arranged on swingably in the described seat portion by connecting portion, so obtained to stablize the armature contact of contact by simple shape.
Because when constituting described armature contact by the rubber-like sheet metal, central authorities in described seat portion have offered the circular arc punching, on the central portion of punching, formed described contact chip, so, owing to can reduce contact resistance, so not necessarily will make fixed contact, thereby can correspondingly reduce cost with precious metals such as gold.
Because described rubber spring is arranged in the described seat portion and described activation projection is pushed described contact chip by the described punching that is arranged on central authorities of described seat portion, so can prolong the stroke of the activation projection of rubber spring by simple structure.
When the bend of described contact chip was configured to contact on the inner bottom surface of described recess, the stress of contact chip was normally certain, so obtained stable contact.
When the bend of described contact chip is configured to break away from the inner bottom surface of described recess, for example when crooked bend, even deviation has appearred in size, because the inner bottom surface of bend contact housing recess is provided with more than the face so can prevent to float on the armature contact housing.
