Abstract
The utility model relates to a structural design for electromagnetic shielding, in particular to a light and thin detachable wire harness electromagnetic shielding element, which comprises conductive cloth, wherein one side edge of the conductive cloth is provided with a conductive adhesive layer, the conductive cloth is also provided with a double-sided adhesive layer, and the double-sided adhesive layer is positioned beside the conductive adhesive layer; thereby form electrically conductive closed loop structure through electrically conductive cloth and conductive adhesive layer and realize the shielding effect to the cable, can fix shielded component on the one hand through the bonding design of double faced adhesive tape simultaneously, guaranteed the stability of being connected between electrically conductive cloth and the cable, on the other hand very be convenient for by the installation and the dismantlement of shielded component, moreover because structure and the shape of electrically conductive cloth itself can be adjusted wantonly, so can compatible cable shielding's under the arbitrary scene application, thereby make whole frivolous detachable pencil electromagnetic shield component can be better realize shielding component's light and thin nature and buckling performance, thereby can adapt to the application scene of cable more.
Description
Technical Field
The utility model relates to a structural design for electromagnetic shield specifically is a frivolous type detachable pencil electromagnetic shield component.
Background
With the development of technology, smart city construction is accelerated everywhere, the city security field is more deepened as a guardian of the city, and data shows that the scale of the security market of China reaches trillions in 2021 year; particularly, the video identification technology is applied to the security protection field of various cities, public places and the like, and brings unprecedented great opportunity; the high-cleanness requirement in the field of security at the present stage is highlighted; the shipment percentage of the existing high-definition camera is about 20%, and the increase of the security camera in the industry for three years is supported by the increase of the proportion.
High resolution support is required for high definition images, so that the requirements for signal transmission are high, and shielding protection for an internal cable (FFC) is necessary to ensure normal signal transmission without interference.
The shielding protection commonly used before is generally realized by using copper material to manufacture a package, and although the shielding effect of the material is good, the cost is high and the weight is heavy, the installation and the disassembly are inconvenient, and the efficiency is lower when the problem occurs and rework and repair are needed.
The applicant proposes an improved design of a changeable detachable wire harness electromagnetic shielding element, which is characterized in that a magic tape hair surface is further arranged on one side of the conductive cloth; be equipped with the magic on the opposite side of electrically conductive cloth and paste the face of colluding, nevertheless because the thickness that the magic was pasted leads to whole pencil electromagnetic shield component's thickness thicker, the line environment of walking of adaptation cable of not being convenient for, because the line environment of walking of part cable is comparatively narrow and small and have a buckling, so the current cable of adaptation that above-mentioned scheme can not be fine walks the line environment requirement.
SUMMERY OF THE UTILITY MODEL
To the problem mentioned in the background art, the utility model provides a frivolous type detachable pencil electromagnetic shield component.
The above technical purpose of the present invention can be achieved by the following technical solutions: the utility model provides a frivolous type detachable pencil electromagnetic shield component, includes electrically conductive cloth, be equipped with conductive adhesive layer on electrically conductive cloth's a side edge, still be equipped with double-sided adhesive layer on the electrically conductive cloth, double-sided adhesive layer is located by conductive adhesive layer.
Preferably, the conductive cloth is further provided with an original film layer, the original film layer is bonded with the conductive cloth, and the original film layer and the conductive glue layer are respectively located on two sides of the conductive cloth.
Preferably, the thickness of the conductive adhesive layer may be 70 μ.
To sum up, the utility model discloses following beneficial effect has: the utility model discloses a frivolous type detachable pencil electromagnetic shield component, thereby form electrically conductive closed loop structure through conductive cloth and conductive adhesive layer and realize the shielding effect to the cable, bonding design through the double faced adhesive tape can fix on the one hand by the component, the stability of being connected between conductive cloth and the cable has been guaranteed, on the other hand very is convenient for by the installation and the dismantlement of shielding component, moreover because the structure and the shape of conductive cloth itself can be adjusted wantonly, so can compatible cable shielding's under the arbitrary scene application, thereby make whole frivolous type detachable pencil electromagnetic shield component can be better realize shielding component's light and thin nature and buckle the performance, thereby can the application scene of adaptation cable more.

fig. 2 is a schematic view of the usage state of the present invention.
Description of reference numerals: 1. a conductive cloth; 2. a conductive adhesive layer; 3. a double-sided adhesive layer; 4. a primary membrane layer; 5. a cable.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
A light and thin detachable wire harness electromagnetic shielding element comprises conductive cloth 1, wherein a conductive adhesive layer 2 is arranged on one side edge of the conductive cloth 1, a double-sided adhesive layer 3 is further arranged on the conductive cloth 1, and the double-sided adhesive layer 3 is positioned beside the conductive adhesive layer 2; the conductive cloth 1 is also provided with an original film layer 4, the original film layer 4 is bonded with the conductive cloth 1, and the original film layer 4 and the conductive adhesive layer 2 are respectively positioned at two sides of the conductive cloth 1; the thickness of the conductive adhesive layer may be 70 μ.
In specific implementation, after the cable 5 is installed, the double-sided adhesive tape on the conductive cloth 1 is firstly bonded and fixed with the cable 5, and then the conductive adhesive layer 2 on one side of the conductive cloth 1 is bonded with the other side of the conductive cloth 1, so that the conductive cloth 1 and the conductive adhesive layer 2 can form a conductive closed-loop structure, the shielding effect on the cable 5 is effectively realized, and meanwhile, the double-sided adhesive layer 3 can be bonded with the cable 5, so that the position of the conductive cloth 1 on the cable 5 is stable; the coarse estimate, based on frequency, can achieve a shielding effectiveness of 60 dB.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
