Description

A kind of wane type switch

Technical field

The utility model relates to a kind of mains switch, particularly a kind of wane type switch.

Background technology

At present; The utility model patent that is called " wane type switch " by the applicant application and the name that obtains authorizing is disclosed on the State Intellectual Property Office website; This wane type switch is through setting up the stage clip shell fragment that a middle part is provided with groove between fork and seesaw, and stage clip shell fragment two ends are connected with the seesaw two ends respectively, and the simple structure that simultaneously the fork lower end is withstood in the groove has realized that fork fiddles with to seesaw; Thereby the wearing and tearing of fork lower end have not only been reduced; Increase the useful life of wane type switch, but also simplified the assembling of wane type switch, improved the dependability of wane type switch simultaneously.But; In actual application; The applicant finds that there is a weak point in the wane type switch of said structure: promptly the stage clip shell fragment can receive fork lower end applied pressure generation strain and produce back stretch; And this back stretch can be delivered to the spike place, two ends of stage clip shell fragment along two circular arc shell fragments of stage clip shell fragment; Downward pressure becomes comparatively smooth because of two ends receive to make seesaw, and this can cause being connected the moving contact at seesaw two ends and the electric clearance that is connected between the fixed contact on the fixed contact support diminishes, thereby makes wane type switch because of normal use of the not enough influence of the electric clearance between moving contact and the fixed contact easily.

The utility model content

The technical problem that the utility model will solve is, provides a kind of seesaw can compressive deformation, thereby can effectively prevent to influence the wane type switch of normal use because of the electric clearance between moving contact and the fixed contact diminishes.

For solving the problems of the technologies described above, the utility model provides a kind of wane type switch of following structure: comprise drain pan, fork, seesaw, the stage clip shell fragment that is connected with seesaw, the loam cake that is connected with drain pan and the fixed support that is positioned at drain pan, be provided with fast-wiring mechanism between drain pan and the fixed support; Fork and drain pan upper end are rotatably connected, and the fork upper end is connected with button, is connected with seesaw support and two fixed contact supports that are provided with fixed contact on the fixed support; The seesaw frame is on the seesaw support; The two ends of seesaw are equipped with moving contact and hole clipping, and stage clip shell fragment two ends are equipped with and are used for the spike that matches with hole clipping, and the fork lower end withstands in the groove of being located at stage clip shell fragment middle part; Wherein, Be provided with horizontal shell fragment and inclination shell fragment symmetrically on the stage clip shell fragment between groove and two spikes, have angle between horizontal shell fragment and the inclination shell fragment, have angle β between inclination shell fragment and the spike; The spike lower end is provided with card base, has angle γ between card base and the spike.

The described a kind of wane type switch of the utility model, wherein, the angle of angle is 163 ~ 167 degree, and the angle of angle β is 103 ~ 107 degree, and the angle of angle γ is 148 ~ 152 degree.

The described a kind of wane type switch of the utility model, wherein, the angle of angle is 163 degree or 165 degree or 167 degree, the angle of angle β is 103 degree or 105 degree or 107 degree.

The described a kind of wane type switch of the utility model, wherein, the angle of angle γ is 148 degree or 150 degree or 152 degree.

After adopting said structure; Compared with prior art; The utlity model has following advantage: because a kind of wane type switch of the utility model has been made into the stage clip shell fragment of groove both sides the multiaspect shape be made up of horizontal shell fragment, inclination shell fragment and spike by original circular arc; And have angle between horizontal shell fragment and the inclination shell fragment, have angle β between inclination shell fragment and the spike, therefore; Behind stage clip shell fragment compressive deformation; The back stretch of its generation is concentrated in junction and the inclination shell fragment and the junction of spike rather than the spike place that cooperates with the seesaw two ends of horizontal shell fragment and inclination shell fragment, thereby has reduced spike greatly to the downward pressure that the seesaw two ends are applied, and seesaw can be held its shape; And then prevented that effectively the situation that the electric clearance between moving contact and the fixed contact diminishes because of seesaw from taking place, and guaranteed the normal use of a kind of wane type switch of the utility model.In addition; The effect that is located at the card base of spike lower end in a kind of wane type switch of the utility model is with after seesaw is connected at the stage clip shell fragment; Card base can be clamped on the hole clipping lower end to guarantee that spike cooperates with the effective of hole clipping, and the situation of avoiding coming off because of angle is excessive between spike and the hole clipping takes place.
