Abstract
The utility model relates to the technical field of a silicone key, and especially relates to a waterproof silicone key which comprises a metal piece, an adhesive layer coated on the metal piece, and a silicone layer which is vulcanized and bonded to the whole surface of adhesive layer. The silicone layer is provided with a groove used for marking a letter or a number. Since the whole surface of the metal piece is coated with the adhesive layer and the silicone layer is bonded on the whole surface of the adhesive layer through hot vulcanization, the combined degree of the metal piece and the silicone layer is strong, and the performance of the waterproof silicone key is stable. Moreover, since the silicone layer is provided with the groove for marking the letter or number, and according to the letter or number marked by the groove, the marking as the subsequent processing is facilitated.
Description
Technical field
The utility model relates to the silica gel push-button technical field, particularly relates to a kind of water-proof silica-gel button.
Background technology
The structure of the water-proof silica-gel button in the existing electronic product comprises the reinforcement metal sheet, and this reinforcement metal sheet is coated with an interface agent layer respectively in two surfaces up and down, and this two interfaces agent layer is respectively arranged with a layer of silica gel.Water-proof silica-gel button of the prior art, up and down two surfaces are bonding with layer of silica gel because the reinforcement metal sheet has only, and therefore, the bonding conjugation of reinforcement metal sheet and layer of silica gel is strong inadequately, causes the performance of water-proof silica-gel button to be stablized inadequately.
Summary of the invention
The purpose of this utility model is to provide a kind of water-proof silica-gel button at weak point of the prior art, and in this water-proof silica-gel button, the bonding conjugation of sheet metal and layer of silica gel is strong, thereby makes the stable performance of this water-proof silica-gel button.
For achieving the above object, the utility model is achieved through the following technical solutions.
A kind of water-proof silica-gel button is provided, comprises sheet metal, be coated on the adhesive phase of described sheet metal all surfaces and the layer of silica gel that heat cure is bonded in described adhesive phase all surfaces.
Described layer of silica gel is provided with the groove for the mark letter or number.
Described groove be shaped as rectangle.
The thickness of described adhesive phase is 25 μ m ~ 50 μ m.
The thickness of described adhesive phase is 40 μ m.
The thickness of described layer of silica gel is 0.05mm ~ 0.2mm.
Described sheet metal is stainless steel substrates.
The beneficial effects of the utility model: a kind of water-proof silica-gel button of the present utility model comprises sheet metal, is coated on the adhesive phase of sheet metal all surfaces and the layer of silica gel that heat cure is bonded in the adhesive phase all surfaces; Layer of silica gel is provided with the groove for the mark letter or number.Because all surfaces of sheet metal is coated with adhesive phase, and layer of silica gel is all surfaces that is bonded in adhesive phase by heat cure, so the bonding conjugation of sheet metal and layer of silica gel is strong, thereby makes the stable performance of this water-proof silica-gel button.And because layer of silica gel is provided with the groove for the mark letter or number, the letter or number of this groove mark is convenient to the mark as the following process operation.
Description of drawings
Fig. 1 is the structural representation of a kind of water-proof silica-gel button of the present utility model.
In Fig. 1, include:
1---sheet metal,
2---adhesive phase,
3---layer of silica gel, 31---groove.
Embodiment
The utility model is described in further detail with the following Examples.
See Fig. 1.A kind of water-proof silica-gel button of present embodiment comprises sheet metal 1, is coated on the adhesive phase 2 of sheet metal 1 all surfaces and the layer of silica gel 3 that heat cure is bonded in adhesive phase 2 all surfaces.Wherein, sheet metal 1 all surfaces refers to six surfaces of sheet metal 1, and adhesive phase 2 all surfaces refer to six surfaces of adhesive phase 2, and six surfaces comprise upper and lower surface, left and right side and front and back sides.Because six surfaces of sheet metal 1 are coated with adhesive phase 2, and layer of silica gel 3 is six surfaces that are bonded in adhesive phase 2 by heat cure, so the bonding conjugation of sheet metal 1 and layer of silica gel 3 is strong, thereby makes the stable performance of this water-proof silica-gel button.
In the present embodiment, layer of silica gel 3 is provided with the groove 31 for the mark letter or number.This groove 31 be shaped as rectangle.Certainly, according to needs of production, the shape of groove 31 also can be other shapes, for example: triangle, circle, ellipse or have the polygon at least five limits.The letter or number of this groove mark is convenient to the mark as the following process operation.
In the present embodiment, the thickness of adhesive phase 2 is 40 μ m.The adhesive phase 2 of this thickness has stronger bonding force makes sheet metal 1 and layer of silica gel 3 good bond together, and simultaneously, the adhesive phase 2 of this thickness can not influence the performance of this water-proof silica-gel button.
In the present embodiment, the thickness at layer of silica gel 3 further groove 31 places is 0.05mm, and other thickness except groove 31 places in the layer of silica gel 3 is 0.1mm.Layer of silica gel 3 with above-mentioned thickness can play water-proof function, simultaneously also can economical with materials, reduce production costs.
In the present embodiment, sheet metal 1 is stainless steel substrates, thereby makes this sheet metal 1 be not easy to get rusty.
The embodiment 2 of a kind of water-proof silica-gel button of the present utility model, the difference of present embodiment and embodiment 1 is, the thickness of adhesive phase 2 is 25 μ m, and the adhesive phase 2 of this thickness has enough strong bonding force makes sheet metal 1 and layer of silica gel 3 good bond together; The thickness at layer of silica gel 3 further groove 31 places is 0.12mm, and other thickness except groove 31 places in the layer of silica gel 3 is 0.2mm, and the layer of silica gel 3 with above-mentioned thickness can play fine water-proof function.Other structure and the operation principle of present embodiment are identical with embodiment 1, do not repeat them here.
The embodiment 3 of a kind of water-proof silica-gel button of the present utility model, the difference of present embodiment and embodiment 1 is, the thickness of adhesive phase 2 is 50 μ m, the adhesive phase 2 of this thickness has very strong bonding force makes sheet metal 1 and layer of silica gel 3 good bond together, and the adhesive phase 2 of this thickness can not influence the performance of this water-proof silica-gel button; The thickness at layer of silica gel 3 further groove 31 places is 0.08mm, and other thickness except groove 31 places in the layer of silica gel 3 is 0.15mm, and the layer of silica gel 3 with above-mentioned thickness can play fine water-proof function.Other structure and the operation principle of present embodiment are identical with embodiment 1, do not repeat them here.
Should be noted that at last; above embodiment only is used for the explanation the technical solution of the utility model but not to the restriction of the utility model protection range; although with reference to preferred embodiment the utility model has been done detailed description; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement the technical solution of the utility model, and not break away from essence and the scope of technical solutions of the utility model.
