Description
Technical field
The invention mainly relates to electronic product or the waterproof correlative technology field of equipment, specifically a kind of electronic product is mechanical
Formula key water-proof structure.
Background technique
To existing electronic product or equipment with mechanical key, mainly by two kinds of waterproof forms:
The first: having hole location to correspond to key in keys upwards plus a lid, lid.The surface of lid, then with glue or
One layer of sheet or silica gel piece on double faced adhesive tape, water would not enter from key again.
Second: there is hole location to correspond to key in keys upwards plus a lid, lid, a flexible glue lid is added at hole location,
Flexible glue lid front is squeezed with another part by ultrasonic bonding or lock screw etc. modes front, thus make water will not again from
It is penetrated at key, reaches waterproof effect.
First way, it is fairly simple, but waterproofing grade is not high, generally can only achieve IP56 grades of waterproofing grade hereinafter,
It is unable to reach and reaches IP67 or IP68 grades of higher level.
The second way can achieve relatively high waterproofing grade, but production technology is complicated, need profession equipment or
More parts go assembling to squeeze flexible glue lid.For example by ultrasonic bonding, the bonding machine of profession is needed, increases production indirectly
Difficulty or cost.If compressing flexible glue lid by lock screw, needs multiple screws and more manually go to assemble, increase a production
The cost of material and cost of labor of product.
Summary of the invention
For the deficiency for solving current technology, the present invention combination prior art provides a kind of structure letter from practical application
The high electronic product mechanical key waterproof construction of list, good water-proof effect, anti-water stability.
Technical scheme is as follows:
A kind of electronic product mechanical key waterproof construction, in the electronic product with mechanical key, including
Flexible glue lid, the flexible glue lid are embedded in the mounting hole for corresponding to mechanical key on electronic product casing, and flexible glue lid is embedding
Enter its rear lateral surface to be extruded on the side wall of mounting hole；
Fastener, the fastener are inserted into the opening in flexible glue base portion by interior of shell, and after fastener insertion, lateral surface is squeezed
In on the side wall of flexible glue lid bottom opening.
Flexible glue base portion has position-arresting disk, and the limit dish external diameter is greater than mounting hole aperture, for preventing flexible glue lid
Deviate from by mounting hole.
The fastener has limiting stand, and the limiting stand is resisted against on the position-arresting disk after fastener insertion.
The shell upper installing hole external circumferential has several locating slots, and the position-arresting disk circumferentially has several positioning logical
Hole, the limiting stand circumferentially have several positioning columns, are passed through in positioning through hole insertion locating slot by positioning column and realize flexible glue
Lid is fixed.
The shell upper installing hole external circumferential has several positioning columns, if the position-arresting disk, limiting stand circumferentially all have
Dry positioning through hole, by positioning column insertion position-arresting disk, limiting stand circumferential direction positioning through hole in realization flexible glue lid fix.
There is the through-hole passed through for mechanical key press section on the fastener.
After the fastener installation, bottom is supported by the step of mechanical key.
It is equipped with back-off on the housing, after the fastener installation, bottom can be blocked by the back-off of shell.
The flexible glue lid is silica gel lid.
There is the protrusion for pressing mechanical key in the flexible glue lid.
Beneficial effects of the present invention:
1, the present invention is suitable for almost in all electronic products with mechanical key or equipment, has part few, anti-
The advantage that water effect is good, anti-water stability is high, the waterproof service life is long, when processing and fabricating, do not have to professional equipment and assembling are gone to produce, unskilled labourer
Factory can do high-grade waterproof product.
2, present invention assembly is simple, only need to by silica gel lid with shell and fastener association together with, when assembly with compared with
High efficiency and lower labor intensity.
3, for the present invention under identical waterproof requirement, so that the cost of product is lower, product has more the market competitiveness, is convenient for
It promotes the use of.
4, a variety of specific fixed forms provided by the invention, can be realized the quick assembling of silica gel lid, shell and fastener,
It can guarantee the firm fixation of silica gel lid after assembling simultaneously, silica gel lid falls, deviates from caused by drawing will not be pulled because of user.

Specific embodiment
With reference to the drawings and specific embodiments, the invention will be further described.It should be understood that these embodiments are merely to illustrate
The present invention rather than limit the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, this field
Technical staff can make various changes or modifications the present invention, and such equivalent forms equally fall within range defined herein.
The present invention can be applied in nearly all electronic product with mechanical key or equipment to be a kind of, when using such as
Shown in Fig. 1, flexible glue lid 2 pressing disposition outside electronic product casing, by pressing flexible glue lid 2 realize mechanical key pressing with
And water-proof function.
Embodiment 1:
As shown in figs. 2 to 4, a kind of electronic product mechanical key waterproof construction corresponds to machine in the shell of electronic circuit board
Load onto silica gel lid 2 or other flexible glue lids that a bottom has opening in the mounting hole 5 of 4 position of tool formula key, silica gel lid 2 it is outer
