Abstract
The utility model relates to a special-shaped conductive foam comprising a conductive fiber layer and a foam body. The conductive fiber layer is arranged outside the foam body. Conductive fibers are interweaved to form the conductive fiber layer. The conductive fibers are sequentially composed of an anti-oxidation layer, a conductive layer and a fibrous layer from outside to inside. A bonding layer is arranged between the conductive fiber layer and the foam body. The foam body is internally provided with a cavity. The anti-oxidation layer is made of nickel material. The conductive layer is made of copper material. According to the technical scheme of the utility model, the special-shaped conductive foam is reasonable in structure. Based on the combination of copper material with nickel material, the special-shaped conductive foam is excellent in conductivity and shielding effect. Within the frequency range of 100 KHz to 10 GHz, the conductive foam is good in shielding effect.
Description
Technical field
The utility model relates to electronic components, particularly a kind of special-shaped conducting foam.
Background technology
Fiber abnormity conducting foam is to be used between equipment and electronic product enclosure and electronic component, plays that screen is worn-out, damping, conducting ground connection act on.Existing fiber abnormity conducting foam is generally comprised of three-decker: fiber abnormity conducting foam, conducting resinl and the protection separated type material that can tear.Its thickness all below 5mm, the application scenario special to some, for example, two contact mechanisms distant (being greater than 5mm) or foam compressive deformation require larger situation, are difficult to meet instructions for use.
The shielding product in market is of a great variety, has metal species product, the macromolecule silicone rubber products that electrically conductive particles is filled etc.Comparatively speaking, material therefor price, the manufacturing equipment cost of these products are higher, manufacturing process flow is more complicated, the price of product on market is higher, this just limited this series products some need electromagnetic shielding similar functions and the system that must control cost on application.
Utility model content
For the defect existing in prior art, the purpose of this utility model is to provide a kind of special-shaped conducting foam.
For reaching above object, the technical scheme that the utility model is taked is:
A special-shaped conducting foam, comprises conductive fiber layer and foam body, and described conductive fiber layer is arranged at the outside of described bubble face body, and described conductive fiber layer is formed by conductive fiber braiding; Described conductive fiber is from being followed successively by outside to inside anti oxidation layer, conductive layer and fibrage; Between described conductive fiber layer and foam body, adhesive linkage is set; Described foam body interior arranges cavity; Described anti oxidation layer is nickel metal; Described conductive layer is copper metal.
On the basis of such scheme, described foam body is polyurethane.
On the basis of such scheme, described fibrage is polyester fiber.
The beneficial effects of the utility model: rational in infrastructure, the combination of copper and mickel provides splendid conductivity and shield effectiveness, abnormity conducting foam can obtain good shield effectiveness at 100KHz to the frequency range of 10GHz, be applicable to the limited occasion of capacity and clossing pressure, expense is low, requiring the occasion of the high-performance shielding of good stickiness to be particularly suitable for using, be widely used in electronic cabinet, casing, indoor cabinet, industrial equipment, notebook computer, mobile communication equipment etc.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is the utility model structural representation;
Fig. 2 is conductive fiber structural representation described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of special-shaped conducting foam, comprises conductive fiber layer 1 and foam body 3, and described conductive fiber layer 1 is arranged at the outside of described bubble face body 3, it is characterized in that described conductive fiber layer 1 is formed by conductive fiber braiding; Described conductive fiber is from being followed successively by outside to inside anti oxidation layer 11, conductive layer 12 and fibrage 13; Between described conductive fiber layer 1 and foam body 3, adhesive linkage 2 is set; Described foam body 3 inside arrange cavity 4; Described anti oxidation layer 11 is nickel metal; Described conductive layer 12 is copper metal.Described foam body 3 is polyurethane.Described fibrage 12 is polyester fiber.
By copper metal and nickel metal, be attached on fiber and made conductive fiber, be woven into afterwards conductive fiber layer 1, wire performance and shield effectiveness are better.
With way of example, the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
