Abstract
The utility model discloses a kind of bellows conducting foam, comprises columniform hollow body, the lateral surface of hollow body is disposed with pet layer, conductive fabric and overcoat; It is outer and be molded as one with described pet layer that described conductive fabric is coated on described pet layer; Described overcoat is pasted onto on conductive fabric by tack coat; The outer surface of described overcoat is ripple type.The utility model is reasonable in design, reduces the cost of manufacture of conducting foam, has good enabling capabilities, conductive capability and protective capacities, realize conducting foam conductivity and stability organically unification.
Description
Technical field
The utility model belongs to conducting foam field, specifically, relates to a kind of bellows conducting foam.
Background technology
Along with the development of electronic technology, the harm that electromagnetic radiation brings to environment and human body is more and more serious, how to reduce electromagnetic radiation and becomes various countries' question of common concern.In concrete design of electronic products, usual needs are at electronic product positioned inside conducting foam, conducting foam be used on the one hand screening electron product work time the electromagnetic wave that produces, also can reduce the impact that external electromagnetic ripple works on electronic product itself on the other hand, and the electrostatic of generation outwardly can be derived and prevent to produce too much electrostatic.
Existing conducting foam is generally foam and conductive fabric is made, and need foam to support the cost of manufacture that improve conducting foam, pressurized flexible type conductivity and stability are not good, cannot realize the organic unity of conducting foam conductivity and stability.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provide a kind of reasonable in design, there is good enabling capabilities, conductive capability and protective capacities, realize the bellows conducting foam of conducting foam conductivity and stability organic unity.
For solving the problem, the technical scheme that the utility model adopts is:
A kind of bellows conducting foam, is characterized in that: comprise columniform hollow body, the lateral surface of hollow body is disposed with pet layer, conductive fabric and overcoat; It is outer and be molded as one with described pet layer that described conductive fabric is coated on described pet layer; Described overcoat is pasted onto on conductive fabric by tack coat; The outer surface of described overcoat is ripple type.
As a kind of technical scheme of optimization, described hollow body position is semi-cylindrical fiber cavity.
As a kind of technical scheme of optimization, described overcoat comprises nonwoven fabrics and metal protection silk screen, and metal protection silk screen is arranged in nonwoven fabrics.
As a kind of technical scheme of optimization, the Thickness Ratio of described pet layer, conductive layer and overcoat is (1-1.2): (0.9-1.2): (1-1.5).
Owing to have employed technique scheme, compared with prior art, the utility model is reasonable in design, reduces the cost of manufacture of conducting foam, has good enabling capabilities, conductive capability and protective capacities, realize conducting foam conductivity and stability organically unification.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail simultaneously.
Accompanying drawing explanation
Fig. 1 is the cross section structure schematic diagram in a kind of embodiment of the utility model.
Embodiment
Embodiment:
As shown in Figure 1, a kind of bellows conducting foam, comprises columniform hollow body 4, the lateral surface of hollow body is disposed with pet layer 3, conductive fabric 2 and overcoat 1.It is outer and be molded as one with described pet layer that described conductive fabric 2 is coated on described pet layer 3.Described overcoat is pasted onto on conductive fabric by tack coat.The outer surface of described overcoat is ripple type.
In the present embodiment, described hollow body 1 is in semi-cylindrical fiber cavity.Described conductive fabric also can replace with other forms of conductive layer.
In the present embodiment, described overcoat 1 comprises nonwoven fabrics and metal protection silk screen, and metal protection silk screen is arranged in nonwoven fabrics.Overcoat 1 has good cut-protection, prevents scratching performance, can play effective protective effect.
For the needs that reality uses, the present embodiment additionally provides a technical scheme optimized, that is: the Thickness Ratio of described pet layer, conductive layer and overcoat is (1-1.2): (0.9-1.2): (1-1.5).The bellows conducting foam be made up of aforementioned proportion, has best result of use.
The utility model is reasonable in design, reduces the cost of manufacture of conducting foam, has good enabling capabilities, conductive capability and protective capacities, realize conducting foam conductivity and stability organically unification.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change made under enlightenment of the present utility model, and every have identical or akin technical scheme with the utility model, all belongs to protection range of the present utility model.
