Description

Changeable detachable pencil electromagnetic shield component

Technical Field

The utility model relates to a structural design for electromagnetic shield specifically is a changeable detachable pencil electromagnetic shield component.

Background

With the development of technology, smart city construction is accelerated everywhere, the city security field is further developed as a guardian of a city, data is displayed, and the scale of the security market of China reaches trillions in 2020. Particularly, the video identification technology is applied to the security protection field of various cities, public places and the like, and brings unprecedented great opportunities. At the present stage, the high-definition demand in the security protection field is highlighted, relevant data are displayed, the shipment percentage of the existing high-definition camera is about 20%, and the increase of the security protection camera in the industry for three years is supported by the improvement of the percentage.

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.

SUMMERY OF THE UTILITY MODEL

To the problem mentioned in the background art, the utility model provides a changeable detachable pencil electromagnetic shield component has with low costs, light loading and unloading and the stable characteristics of shielding effect.

The above technical purpose of the present invention can be achieved by the following technical solutions: a changeable detachable wire harness electromagnetic shielding element comprises conductive cloth, wherein a magic tape matt surface is further arranged on one side of the conductive cloth; the hook-and-loop fastener is characterized in that a hook-and-loop fastener face is arranged on the other side of the conductive cloth, the hook-and-loop fastener further comprises conductive foam, the conductive foam is arranged on one side of the conductive cloth, a double-faced adhesive tape is further arranged on the conductive cloth, and the double-faced adhesive tape is located between the hook-and-loop fastener face and the hook-and-loop fastener rough face.

Preferably, the magic tape hair side is at least two groups and is arranged in parallel.

Preferably, the hook and loop fastener surfaces are at least two groups and arranged in parallel.

Preferably, the conductive foam is arranged between the two groups of hook and loop fastener rough surfaces or between the two groups of hook and loop fastener hook surfaces.

Preferably, the conductive foam is 4T high-density full-conductive foam.

To sum up, the utility model discloses following beneficial effect has: the utility model discloses a thereby changeable detachable pencil electromagnetic shield component realizes the shielding effect to the cable through electrically conductive cloth and the cotton electrically conductive closed loop structure that forms of electrically conductive bubble, and the bonding design of pasting through the magic simultaneously can make shielding component's installation and dismantlement all very convenient, and the design of double faced adhesive tape has guaranteed the stability of being connected between electrically conductive cloth and the cable, moreover because the structure and the shape of electrically conductive cloth itself can be adjusted wantonly, so can compatible cable shielding's under the arbitrary scene application.
