Description
Technical field
This utility model relates to a kind of switch.
Background technology
Microswitch is widely used in the electronic products such as mobile phone, camera, panel computer. But existing microswitch exists gap due to the junction of its upper cover and base, therefore will cause that steam penetrates into switch internal, and make the internals of switch or even electronic product make moist corrosion.
Therefore those skilled in the art are devoted to develop a kind of better microswitch of humidity resistance.
Utility model content
Because the drawbacks described above of prior art, technical problem to be solved in the utility model is to provide a kind of better microswitch of humidity resistance.
For achieving the above object, this utility model provides a kind of microswitch, including upper cover, shell fragment, base portion and circuit board; The middle part of described upper cover is provided with the portion of pressing; Described upper cover described press portion be arranged below contact part; Described shell fragment is positioned at the lower section of described contact part;
Described upper cover is disposed with First terrace, second step face and the 3rd step surface from the close-by examples to those far off, from high to low by described contact part;
Described base portion includes the base being combined with described upper cover; Described base is provided with the storage tank holding described shell fragment; Described base is provided with fourth step surface corresponding with described First terrace, second step face and the 3rd step surface, the 5th step surface and the 6th step surface;
Described circuit board is arranged in described storage tank; The middle part of described circuit board is provided with middle junction, and both sides are respectively arranged with the first side junction and the second side junction; Described first side junction and the second side junction stretch out described base.
The beneficial effects of the utility model are: this utility model simple in construction, seal tight, and humidity resistance is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model one detailed description of the invention.
Fig. 2 is working state schematic representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As it is shown in figure 1, a kind of microswitch, including upper cover 10, shell fragment 20, base portion 30 and circuit board 40. The middle part of upper cover 10 is provided with the portion of pressing 12, and upper cover 10 is arranged below contact part 13 in the portion of pressing 12, and shell fragment 20 is positioned at the lower section of contact part 13.
Upper cover 10 is other in contact part 13 is disposed with First terrace, second step face and the 3rd step surface from the close-by examples to those far off, from high to low.
Base portion 30 includes the base 31 being combined with upper cover 10, and base 31 is provided with the storage tank 311 holding shell fragment 20, and base 31 is provided with fourth step surface corresponding with First terrace, second step face and the 3rd step surface, the 5th step surface and the 6th step surface.
Circuit board 40 is arranged in storage tank 311, and the middle part of circuit board 40 is provided with middle junction 32, and both sides are respectively arranged with the first side junction 33 and the second side junction 34, and the first side junction 33 and the second side junction 34 stretch out base 31.
As in figure 2 it is shown, press contact part 13, junction the 32, first side junction 33 and the second side junction 34 in making contact part 13 connect, thus switching on power.
Preferred embodiment of the present utility model described in detail above. Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work. Therefore, all technical staff in the art pass through the available technical scheme of logical analysis, reasoning, or a limited experiment on the basis of existing technology according to design of the present utility model, all should in the protection domain being defined in the patent claims.
