Abstract
The utility model discloses a light touch waterproof switch structure, which comprises a substrate, a cover plate, a button, a spring piece and a waterproof membrane, wherein the substrate is buckled with the cover plate to form a shell; the waterproof membrane is arranged on an upper port of the substrate; the circumferential side of the waterproof membrane is fixedly connected with a contact surface of the substrate by the cover plate; the waterproof membrane is positioned between the button and the spring piece; and the button can be displaced up and down and simultaneously press the waterproof membrane plus the spring piece below the button to deform, so as to turn on or turn off the switch. As a dustproof membrane and an internal button are omitted from the light touch waterproof switch structure, the structure is assembled more compactly; and the light touch waterproof switch structure has the advantages of reasonableness in structure, safety, reliability, and the like, and is particularly suitable for small size household appliances.

Traditional switch generally comprises pedestal, loam cake, button and shell fragment, when user's pressing keys, and shell fragment distortion and make the Switch main body conducting; When resetting, switch is off-state.So, this switch is not provided with waterproof sealing structure, and slit and the slit of button and cover plate mating holes of liquid between meeting is fitted by loam cake and pedestal enters in the pedestal, causes the loose contact of switch even can't connect and operate as normal.
Chinese patent document CN200820145515.0 discloses a kind of water proof type touch-switch, comprises pedestal, cover plate, shell fragment and button, is provided with waterproof membrane and dustproof film between shell fragment and the button, and the shell fragment end face is provided with button in, and button top end face is in abutting connection with dustproof film in this.Though document scheme can reach the waterproof purpose, because the existence of dustproof film and interior button make its structure assembling complicated, and the specification of product is relatively large, is not suitable for small household appliances and uses.
Summary of the invention
To the deficiency of prior art, the utility model provides a kind of rational in infrastructure, safe and reliable water proof switch structure of touching.
For achieving the above object, the utility model is realized through following technical scheme:
A kind of water proof switch structure of touching; Comprise pedestal, cover plate, button, shell fragment and waterproof membrane; Pedestal and cover plate fasten and form housing, and described pedestal port is provided with waterproof membrane, and all sides of this waterproof membrane are fixed by cover plate and pedestal contact-making surface; Waterproof membrane is between button and the shell fragment, and the waterproof membrane of pushing simultaneously below it by the upper and lower displacement of bond energy makes switch conduction or disconnection together with the shell fragment distortion.
Further, the described button center perforation that is arranged in cover plate that stretches out is exposed to outside the housing, and the projection edge of button periphery breaks away from housing greater than the center perforation of cover plate to prevent button, and the button bottom has the center that a projection presses on waterproof membrane and shell fragment.
Further, be provided with center contact and contact, both sides in the described pedestal, the contact, both sides is on same plane and be higher than center contact, and the bottom of pedestal is provided with the terminal that is connected with center contact and side contact respectively, and pedestal and terminal are injected into one.
Further, be extended with lead on the described susceptor edge angle, corresponding with the position, hole that cooperates on the cover plate, and the end face that contacts of cover plate and pedestal is provided with annular projection and fixes with tight extruding waterproof membrane.
The utility model is owing to omitted dustproof film and interior button; Make the structure assembling compact more; The material of the waterproof membrane of the utility model employing simultaneously is rubber T=0.30 Shao Shi 35 degree; It can be out of shape and make switch conduction or disconnection by depressing button with shell fragment, and switching function does not have damage the utility model soaks 240H in 10cm and temperature are 60 ℃ water after.
The utlity model has following useful effect:
1, the utility model stops water or other liquid to enter in the pedestal because a waterproof membrane is set above the contact effectively, plays the waterproof purpose, has avoided situations such as contact is perishable and aging to take place;
2, the utlity model has rational in infrastructure, security performance advantages of higher;
3, the utility model action force: 250 ± 50gf, useful life: 100000 cycler Min.

Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Embodiment: see also Fig. 1 to Fig. 7; A kind of water proof switch structure of touching comprises pedestal 5, cover plate 2, button 1, shell fragment 4 and waterproof membrane 3, and pedestal 5 fastens with cover plate 2 and forms housing; Described pedestal 5 port are provided with waterproof membrane 3; The all sides of this waterproof membrane are fixed by cover plate 2 and pedestal 5 contact-making surfaces, and waterproof membrane 3 is between button 1 and the shell fragment 4, and the waterproof membrane 3 that the upper and lower displacement of button 1 ability is pushed below it simultaneously makes switch conduction or disconnection together with shell fragment 4 distortion.The described button 1 center perforation 20 that is arranged in cover plate 2 that stretches out is exposed to outside the housing; The projection edge 10 of button 1 periphery breaks away from housing greater than the center perforation of cover plate to prevent button, and button 1 bottom has the center that a projection 11 presses on waterproof membrane 3 and shell fragment 4.Be provided with center contact 51 and contact, both sides 52,53 in the described pedestal 5, the contact, both sides is on same plane and be higher than center contact, and the bottom of pedestal is provided with the terminal 6 that is connected with center contact and side contact respectively, and pedestal and terminal are injected into one.Described pedestal 5 corners have extended upward lead 54, and are corresponding with the position, hole 21 that cooperates on the cover plate 2, and 3 four jiaos of waterproof membranes have the breach that cooperates with guide pillar, and the end face that contacts of cover plate and pedestal is provided with annular projection and fixes with tight extruding waterproof membrane.
