Description

A kind of electronic product dust seal
Technical field
The utility model relates to sealing gasket, concrete a kind of electronic product dust seal.
Background technique
The shell of electronic product is formed by multiple assembling parts usually, usually will bear the functions such as anti-impact, shockproof, shatter-resistant due to above-mentioned shell, and the general larger material of rigidity that adopts is made, as the macromolecular material such as polycarbonate (PC), acrylic.Due to the restriction of the conditions such as technique, material property, mould and die accuracy, between mutually assembled housing contacts face, often easily occur gap, and the higher characteristic of rigidity causes above-mentioned gap to be difficult to by outer force-closed.For the product that some service lives are comparatively remote, due to the reason such as aging of material, gap will increase gradually.Dust in air, organic substance, microorganism, steam etc. enter electronic product inside by gap, cause electronic product internal wiring aging, be corroded.Especially dust is under electrostatic interaction, can be attached to electronical elements surface securely, affects its heat radiation, the final working life shortening electronic product.Prior art, by arranging flexible dust-proof cushion (as silicagel pad) on the surface of contact of shell, by the deformation behavior of silica gel by above-mentioned gap filling, prevents the impurity such as dust from entering electronic product.But existing dust-proof cushion is pursue with the laminating effect of shell, reduce cost of production, and its surface is comparatively smooth, and after assembling product or Long-Time Service, dust-proof cushion easily slides because of the extruding of shell, and generation displacement causes case surface gap to expose.Because its sealing reliability of existing dust-proof cushion is poor, needing badly provides a kind of and seals the dust proof member that grade is high, anti-slip, reliability is strong.
Model utility content
In view of this, high, the skid-resistant use for electronic products dust seal of the open a kind of sealing grade of the utility model.
The purpose of this utility model is achieved through the following technical solutions: a kind of electronic product dust seal, comprises basic unit and covers the deformation layer on basic unit's one or both sides; Described deformation layer surface is provided with the dust-proof groove of multiple tracks.
Basic unit can select the material that mechanical strength is higher, as PET(PETG), the material such as PP, PC, obtain through being squeezed into sheet.Deformation layer then mainly select hardness low, hold yielding material (as silica gel etc.) when being squeezed and make sheet material and obtain.Because deformation layer hardness is lower, be difficult under external force extruding, maintain its shape and affect sealing effect, the utility model designs the higher basic unit of a hardness especially and formalizes to deformation layer, support, make deformation layer remain in the gap of shell and not be moved, improve the sealing effect to gap, housing contacts face.According to the needs of the shape of product, precision and sealing grade, deformation layer can be all set in the side of basic unit or both sides.Deformation layer and basic unit can adopt gummed, cold pressing or the mode of hot pressing is fixed.Especially, the utility model arranges the dust-proof groove of multiple tracks on the surface of deformation layer; Dust-proof groove significantly can increase the surface area of deformation layer, namely the area of contact in deformation layer and housing contacts face is increased, thus improve deformation layer to the bond strength in housing contacts face, prevent deformation layer, under external force extruding, the risk that housing slot is exposed of sliding occurs.Especially, will form many airtight micro air chamber between dust-proof groove and housing contacts face, the air in air chamber has higher pressure because of the extruding of shell, and further tensioning deformation layer makes it to fit tightly with shell.Designer finds, above-mentioned air chamber also can form multiple tracks isolation barrier, and isolated moisture, dust etc. enter enclosure.Especially, dust sealing of the present utility model is paid somebody's debt and expected repayment later has damping effect, prevents electronic product or shell because of collision, shakes and damage.In addition, dust seal also contributes to reducing electronic product casing gap and light leak occurs, and improves Product Visual effect.
Above-mentioned groove can select arbitrary form to be arranged in deformation layer surface, as linear array arranged side by side, staggered linear array, the concentric or staggered polygonal closed, the curvilinerar figure arrangement that curvature arranged side by side is equal, staggered closing or the arrangement of open curve shape.It is emphasized that above for not exclusively to enumerate, not as the restriction to the utility model protection domain.
Particularly preferred, dust-proof groove described in the utility model selects multiple closed or open curve shape arrangement be crisscross arranged, the area of multiple dust-proof groove longitudinal projection is 0.6:1-0.8:1 with the ratio of deformation layer surface area, and the ratio of the hierarchy structure of groove is 1:0.1-1:0.3.
Dust-proof groove area occupy deformation surface layer than higher---i.e. deformation layer surface is provided with more dust-proof grooves---will the area of contact of deformation layer and product casing be reduced, make it to closely cooperate with the surface of contact of shell, reduce the skidproof effect of dust-proof groove on the one hand, gap easily residual larger between deformation layer and shell on the other hand, causes the decline of sealability.And dust-proof groove area is too small, then cannot realize its skidproof effect to deformation layer.Breadth depth ratio is too high or too low will cause same problem.Designer, through long-term experiment and demonstration, obtains optimum dust-proof groove and the area ratio of deformation layer, and designs width and the depth scale of the dust-proof groove mated with this parameter, farthest promote sealing of the present utility model, dust-proof effect.Due in use, sealing gasket likely slides to any direction, selects the slip that multiple dust-proof groove that the is closed or arrangement of open curve shape be crisscross arranged can prevent sealing gasket from going up in any direction.Above-mentioned arrangement mode also helps the uniformity improving air chamber distribution simultaneously, improves sealing effect of the present utility model further.Described deformation layer surface refers to the one side that deformation layer does not contact with basic unit.Especially, on the dust-proof groove of same, the curvature at adjacent two places should be different.Through checking, when the area of multiple dust-proof groove longitudinal projection is 0.6:1-0.8:1 with the ratio of deformation layer surface area, the air chamber cushioning effect formed
Particularly preferred, be provided with dust-proof piece that multiple tracks is vertical in described dust-proof groove; Dust-proof piece of surface is provided with multiple lower concave curved surface.
Dust-proof piece is conducive to dust-proof groove to be divided into multiple minizone, strengthens the intensity of dust-proof groove further, prevents it by conquassation; Dust-proof piece also helps the shock-absorbing capacity improving the utility model dust seal simultaneously.And be arranged on the elastic force that dust-proof piece of surperficial lower concave curved surface can further improve the dust-proof groove of the utility model, strengthen the utility model sealing effect.
