Description
Technical field
The utility model relates to appliance switch field, particularly relates to a kind of switching device.
Background technology
Switching device is just mounted in the appliance switch that wall uses, be used for make-and-break contact use household electrical appliance.
Please refer to Fig. 1, Fig. 1 is the structural representation of a kind of typical switching device in prior art.
Be point cantact between the switch springboard 11 of current most switching device on the market and contact chip 12, contact portion only has the cross-sectional sizes of contact chip 12, and the sectional area of contact chip 12 is less, and contact area is less.When switching device closure or openness, sectional area between switch springboard 11 and contact chip 12 is less, when the resistivity of contact chip 12 and length constant, resistance is corresponding larger, the heat produced is more, temperature is higher, and frequent this switching device that uses easily burns out, and the useful life of switching device reduces.
In sum, how effectively improving the useful life of switching device, is current those skilled in the art's urgent problem.
Utility model content
The purpose of this utility model is to provide a kind of switching device, effectively improves the useful life of switching device.
For solving the problems of the technologies described above, the utility model provides following technical scheme:
A kind of switching device, comprise and being positioned on switch panel for controlling the switch springboard that described switching device opens or cuts out and the contact chip be communicated with power supply, touching described switch springboard can drive described switch springboard to contact with described contact chip or be separated, and described switch springboard and described contact chip are plane-plane contact.
Preferably, described contact chip comprises the arc end that can contact with described switch springboard and the link be communicated with described power supply, and the contact-making surface of described arc end and described switch springboard is specially arc surface.
Preferably, the width of described arc end is greater than the width of described link.
Preferably, bending described arc end and described link one-body molded.
Preferably, described arc end is by being welded to connect the end in described link.
Switching device provided by the utility model, comprise switch springboard and contact chip, switch springboard is positioned on switch panel, touch switch springboard can open or cut out by control switch device, and contact chip is communicated with power supply, and touch switch springboard can contact with contact chip or be separated by driving switch springboard, when switch springboard contacts with contact chip, be plane-plane contact between the two, contact-making surface can be plane, also can be cambered surface.The contact area of plane-plane contact is comparatively large, and namely between switch springboard and contact chip, contact area is comparatively large, when the resistivity of contact chip and length constant, resistance is less, and the heat of generation is less, and temperature is lower, switching device is easy burn-out not, and the useful life of switching device is longer.

Embodiment
Core of the present utility model is to provide a kind of switching device, effectively improves the useful life of switching device.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 2, the structural representation of the switching device that Fig. 2 provides for embodiment a kind of in the utility model.
In a kind of embodiment, switching device provided by the utility model, comprise switch springboard 1 and contact chip 2, switch springboard 1 is positioned on switch panel, and touch switch springboard 1 can open or cut out by control switch device, contact chip 2 is communicated with power supply, touch switch springboard 1 can contact with contact chip 2 or be separated by driving switch springboard 1, when switch springboard 1 contacts with contact chip 2, is plane-plane contact between the two, contact-making surface can be plane, also can be cambered surface.The contact area of plane-plane contact is comparatively large, and namely between switch springboard 1 and contact chip 2, contact area is comparatively large, when the resistivity of contact chip 2 and length constant, resistance is less, and the heat of generation is less, and temperature is lower, switching device is easy burn-out not, and the useful life of switching device is longer.
Above-mentioned switching device is only a kind of preferred version, specifically be not limited thereto, pointed adjustment can be made according to actual needs on this basis, thus obtain different execution modes, contact chip 2 comprises the arc end that can contact with switch springboard 1 and the link be communicated with power supply, and the contact-making surface of arc end and switch springboard 1 is specially arc surface.Contact chip 2 comprises arc end and link, and link is communicated with power supply, and arc end can contact with switch springboard 1, and the curvature of arc end is larger.Touch switch springboard 1, the arc surface contacted as plane-plane contact contacts arc end with switch springboard 1, and contact area is comparatively large, and resistance is less, and the heat of generation is less, not easily produces high temperature, the useful life of extended switch device; Further, arc surface smoother, arc end contacts better with switch springboard 1.
On the basis of above-mentioned embodiment, those skilled in the art can according to the difference of concrete occasion, some changes are carried out to switching device, the width of arc end is greater than the width of link, switch springboard 1 in use, switch springboard 1 increases with the contact area of contact chip 2, and resistance reduces further.It should be noted that, width mentioned here refers to the direction being parallel to arc end axis.
It is important to note that switching device provided by the utility model should not be restricted to this kind of situation, bending arc end and link are formed in one.The arc end of contact chip 2 and link are integrated; arc end is bent to form by contact chip 2; the amount of curvature that arc end is bending does not do further restriction; can according to the different sets itself of concrete service condition; as long as the job requirement increasing contact area between switch springboard 1 and contact chip 2 can be met, all in protection range of the present utility model.
Switching device provided by the utility model, in the immovable situation of other parts, arc end is by being welded to connect the end in link.Arc end and link also can be the two parts be separated, and arc end and link link together, and such as arc end is by being welded to connect the end in link.
In this specification, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
