Abstract
Disclosed is an electromagnetic shielding liner, comprising a foam core, a double faced adhesive tape, and a conductive fiber cloth, wherein the conductive fiber cloth coats the foam core; the double faced adhesive tape is located between the foam core and the conductive fiber cloth, with the two bonding surfaces thereof respectively glued to the foam core and the conductive fiber cloth; and one part of one of the bonding surfaces is exposed from the conductive fiber cloth. In the electromagnetic shielding liner of the utility model, due to the binding force of the double faced adhesive tape exposed from the conductive fiber cloth, the conductive fiber cloth can be clamped between the foam core and the metal conductive surface. Therefore, without any extrusion over the electromagnetic shielding liner, an excellent conduction effect can be generated in the gap filled by the electromagnetic shielding liner.
Description
Technical field
The utility model relates to the electromagnetic shielding field, relates in particular to a kind of electromagnetic shielding liner.
Background technology
Electromagnetic wave is the main mode of electromagnetic energy travels, and during high-frequency circuit work, the outside radiated electromagnetic wave of meeting produces interference to contiguous miscellaneous equipment.On the other hand, the various electromagnetic waves in space also can be sensed in the circuit, and circuit is caused interference.The effect of electromagnetic shielding is to cut off the electromagnetic wave propagation approach, disturbs thereby eliminate.
Electromagnetic shielding liner is the elastomeric material that a kind of surface can be conducted electricity, and electromagnetic shielding liner is installed in the junction of two conducting surfaces, can the slit be filled full, thereby eliminate the conduction discontinuity point.Can know from the operation principle of electromagnetic sealing liner, use the electromagnetic leakage in the slit of electromagnetic shielding liner mainly to determine by the conductivity of gasket material and the contact resistance of contact surface.Therefore, traditional electromagnetic shielding liner generally all need provide certain pressure, to guarantee enough little contact resistance, electromagnetic shielding liner is expressed to a certain degree, just can play shield effectiveness preferably.But, to the power sensitive part,,, can have a strong impact on effect in case pressure is too big like optical system for some.
The utility model content
In view of this, the purpose of the utility model is the electromagnetic shielding liner that provides a kind of effectiveness good.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of electromagnetic shielding liner; It comprises foam core, double faced adhesive tape and conductive fibre fabric; Said conductive fibre fabric coats said foam core; Said double faced adhesive tape is between said foam core and said conductive fibre fabric, and its two adhesive surfaces bond with said foam core and said conductive fibre fabric respectively, and the part of one of them adhesive surface is exposed to outside the said conductive fibre fabric.
Preferably; Said foam core is a rectangular structure; Said double faced adhesive tape is pasted on the face of said foam core; Said conductive fibre fabric is a rectangle, and its relative two ends deviate from the relative two-side adhesive of the adhesive surface of said foam core respectively with said double faced adhesive tape, and said conductive fibre fabric coats face and and respect to one another two sides adjacent with this face that said foam core deviates from said double faced adhesive tape at least.
Preferably, said foam core is an elastomer.
The electromagnetic shielding liner of the utility model; Owing to be exposed to the bonding force of the outer double faced adhesive tape of said conductive fibre fabric; Make conductive fibre fabric can be clipped between foam core and the metallic conduction face; Thereby need not electromagnetic shielding liner is pushed, can between the gap that this electromagnetic shielding liner is filled, produce good conducting effect.

Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As depicted in figs. 1 and 2, a kind of electromagnetic shielding liner comprises foam core 1, double faced adhesive tape 2 and conductive fibre fabric 3.Foam core 1 is an elastomer, and conductive fibre fabric 3 coats foam core 1.Double faced adhesive tape 2 is between foam core 1 and conductive fibre fabric 2, and its two adhesive surfaces bond with foam core 1 and conductive fibre fabric 2 respectively, to connect foam core 1 and conductive fibre fabric 2.The part of an adhesive surface of double faced adhesive tape 2 is exposed to outside the conductive fibre fabric 3.
In a preferred embodiment, foam core 1 is a rectangular structure, and double faced adhesive tape 2 is pasted on the face of foam core 1.Conductive fibre fabric 3 is a rectangle, and its relative two ends deviate from the relative two-side adhesive of the adhesive surface of foam core 1 respectively with double faced adhesive tape 2, and this conductive fibre fabric 3 coats face and and respect to one another two sides adjacent with this face that foam core 1 deviates from double faced adhesive tape 2 at least.
It is understandable that, in other embodiments, also can have hole on the conductive fibre fabric 3, double faced adhesive tape 2 is exposed from hole.
When using this electromagnetic shielding liner, paste on the metallic conduction face that needs shielding being exposed to conductive fibre fabric 3 outer adhesive surfaces on the double faced adhesive tape 2.Because the bonding force of double faced adhesive tape 2 makes conductive fibre fabric 3 be clipped between foam core 1 and the metallic conduction face, thereby need not electromagnetic shielding liner is pushed, and can between the gap that this electromagnetic shielding liner is filled, produce good conducting effect.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection range of the utility model.
