Abstract
The utility model relates to the field of shielding carried out by equipment or elements directed at electric fields or magnetic fields. The utility model especially relates to one kind of conductive foam. The conductive foam comprises rectangular foam bodies and a conductive cloth. The conductive cloth is arranged to circle around the surfaces of the corresponding foam bodies for one round. One end of the conductive cloth is bonded with the external surface of the other end of the conductive cloth. Fixing blue layers are arranged on the bonded portion between one end of the conductive cloth and the external surface of the other end of the conductive cloth. Arc long grooves recessed towards the intermediate portion form in the left and the right sides of the foam body. Setting sheets parallel to the left side surfaces and the right side surfaces of the foam bodies are inlayed in the foam bodies. The two ends of each setting sheet are close to the both ends of the foam body. The surface of the conductive cloth is provided with a metal conducting layer. The arc long grooves are arranged, so that effects of electric conduction and magnetism isolation are enhanced. The sticky layer is arranged, so that fixing effects of the conductive cloth are improved; and the setting sheets are arranged, so that soundness and anti-pressure performance of the foam structure are improved.
Description
Technical field
The utility model relates to equipment or the shielding field of element to electric field or magnetic field, especially relates to a kind of conducting foam.
Background technology
Conducting foam has surface conductivity, can prevent electromagnetic interference.Conducting foam has the shielding material of different section shapes, installation method, UL grade screening effectiveness, and the effect of its formation is not identical yet.Existing conducting foam is to be generally made up of flame-retardant sponge outer wrap conductive fabric, but the fixed effect of the conducting foam of this setting is poor, its outside conductive fabric easily comes off, and easily occurs displacement when foam is subject to External Force Acting, and its anti-pressure ability is poor, be easy to damage by pressure shielding device; And conductive fabric is only set, and conductive effect is poor.
Utility model content
The utility model, in order to overcome the deficiencies in the prior art, provides one to be connected firmly, the conducting foam that resistance to compression is effective.
To achieve these goals, the utility model is by the following technical solutions: a kind of conducting foam, comprise foamed cotton and the conductive fabric of rectangle, and described conductive fabric arranges along surface one circle of foamed cotton, and one end of conductive fabric and the outer surface of its other end are bonding, and its bonding place is provided with fixing glue-line; The left and right side of described foamed cotton forms to umbilicate arc long recess, is inlaid with the setting sheet parallel with foamed cotton left and right side in foamed cotton, and the two ends of setting sheet are near the two ends of foamed cotton; The surface of described conductive fabric is provided with metal conducting layer.Described fixing glue-line has strengthened the fixed effect of conductive fabric, and the length that two long recess are set can extend conductive fabric, and then make to strengthen the conduction of conducting foam, antimagnetic effect; Setting sheet has improved firm shape and the ability of anti-deformation of conductive foam structure, and the two ends of setting sheet are near the two ends of foamed cotton, both there is certain buffering effect, can avoid again it that deformation occurs because pressurized is excessive, further protect the miscellaneous part in foam, shielding device and shielding device, also improve the fastness of foam structure, extended its useful life; Metal conducting layer can further strengthen structural strength and the conductivity of conducting foam.
As preferably, described setting sheet is two steel discs parallel to each other, and wherein a steel disc is near the front side of foamed cotton, and another steel disc is near the rear side of foamed cotton, and a two steel discs side part adjacent to each other overlaps.The structural strength of steel disc is large, and anti-deformation is effective, and two steel discs are set have strengthened the ability that conducting foam bears pressure, and two steel discs one in front and one in back, and its conductive sponge bubble is stressed evenly, and mid portion overlaps each other and can improve overall compression capability.
As preferably, the width of described long recess is 2/3rds of foamed cotton left and right side width.This setting neither can affect the fastness of conductive foam structure, can make again its conduction, every magnetic best results.
In sum, the utlity model has following advantage: be provided with arc long recess, before increasing conduction, every the effect of magnetic, adhesive-layer be set improved the fixed effect difficult drop-off of conductive fabric; And setting sheet is set, strengthen fastness and the compressive property of foam structure.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out to clear, complete description.
As shown in Figure 1, a kind of conducting foam, comprises foamed cotton 1 and conductive fabric 2, and described foamed cotton 1 is strip, and its cross section is rectangle, described conductive fabric 2 arranges around the surface of foamed cotton 1 circle, and the outer wall of the inwall of conductive fabric 2 and foamed cotton 1 is bonding, and one end inner surface of conductive fabric 2 and conductive fabric 2 other end outer surfaces are bonding, its place bonded to each other is provided with fixing glue-line 3 simultaneously, this fixing glue-line is set and can makes the junction fixed effect of conductive fabric better, difficult drop-off, structure is more firm; Further, the left side of described foamed cotton 1 and right side all form to umbilicate long recess 4, and the cross section of this long recess 4 is curved, this long recess is set, increased the surface area of foamed cotton 1, and then increased the area of conductive fabric, reach strengthen conduction, every the effect of magnetic.The surface of described conductive fabric 2 is provided with metal conducting layer 6, arrange this metal conducting layer further strengthened the conduction of conductive fabric, every magnetic effect; And in foamed cotton 1, be inlaid with setting sheet 5,, setting sheet 5 is long rectangle, and setting sheet 5 all be arranged in parallel with left surface and the right flank of foamed cotton 1, and the two ends of the sheet 5 that formalizes are near the two ends of foamed cotton 1.Concrete, described setting sheet 5 is steel disc, and two steel discs are parallel to each other, and wherein a steel disc is near the front side of foamed cotton 1, and another steel disc is near the rear side of foamed cotton 1, and a two steel discs side part adjacent to each other overlaps.
Preferably, the width of the opening part of described long recess 4 is 2/3rds of foamed cotton 1 left surface width, and the width of left surface is identical with the width of right flank, and the width of the opening part of long recess 4 is also 2/3rds of foamed cotton 1 right flank width.
Obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all should belong to the scope of the utility model protection.
