KR20020002453A - Electrified E.M.I. gasket made of electrified fabric or electrified non-fabric, which enables electricity to flow from left to right and from up to down - Google Patents

Abstract

PURPOSE: An electroconductive gasket using conductive fabric and non-woven fabric is provided to absorb or shield static electricity and electromagnetic wave while absorbing external shock as well, thereby improving performance efficiency without structure modification. CONSTITUTION: An electroconductive gasket is manufactured using fabric or non-woven fabric. A conductive material such as nickel is applied to the fabric or non-woven fabric so as to form an electroconductive fabric. The fabric is overlapped by other fabrics with a conductive adhesive, thereby forming electroconductive textile products. A conductive adhesive is also attached on an applying face to which an attachment is applied. The textile products is formed with a plurality of small and complicated gaskets by an auto die cutting machine. Finally, the gaskets have horizontal and vertical conductibility.

Description

Conductive gaskets made of conductive fabrics and conductive non-woven fabrics (surfaces) and electrically conductive up and down (Electrified E.M.I. gasket made of electrified fabric or electrified non-fabric, which enables electricity to flow from left to right and from up to down}

Conventional GASKET, which is used in wireless communication terminals, computers, monitors, microwave ovens, home appliances, game consoles, and sound equipment, is made of sponges of rubbers or polyurethane materials to be cushioned, and molded to fit the equipment, and its surface is conductive. If the shape is simple, such as a wide rectangular shape or a long rod, the surface conduction and the vertical conduction are possible through the conductive fabric fabric covering the surface, but the sealing work (automatic molding cutting by the mold) is required. The small and complex shape of GASKET removes the conductive fabric fabric from the sealing cross-section, so that the surface is energized but not up and down, so the electrostatic or electromagnetic wave absorption and shielding function is insignificant. In order to compensate for this, when making GASKET using a conductive material of metal such as aluminum, there were many limitations in using it as a GASKET because of its weak buffer function, thick thickness, or poor moldability.

The conductive fabric and the nonwoven fabric are combined and processed with conductive adhesive to make the thickness suitable for the device to which the gasket is attached, and the technology to make the gasket fabric for the gasket having the conductivity of the left and right (surface) and the top and bottom conduction while having a buffer function. After molding, the molding is stable and processing to prevent contaminants such as debris, and it has the buffering property that can be used to replace the existing GASKET without changing the structure of the device. Technology to manufacture conductive GASKET

If you select one or more types of conductive fabrics that adhere conductive materials such as nickel to elastic materials such as textiles or nonwoven fabrics, and attach them to each layer with conductive adhesives as needed, attach the conductive surface to the fixture. It is possible to make GASKET fabric which has shock absorbing property and has conductivity which can conduct left and right (surface) and up and down conduction, and it is made by sealing machine (auto die cutting machine) to fit the equipment to which GASKET is attached. The mass gasket can be mass-produced, and thus the gasket is made of gasket having the conductivity which enables the left and right (surface) energization and the up and down energization even after the sealing molding. The GASKET is made of fiber material, so the molding is unstable and easy to be contaminated by debris such as fiber fragments and dust. In order to stabilize the molding of the molded GASKET and to remove contaminants such as fiber fragments and dust, hot wire cutting is performed during sealing. Alternatively, heat the upper and sealed sections of the gasket with a small flamethrower or heater for 0.2-0.5 seconds while heating it, and melt and process the sealing section of the gasket only weakly so as not to damage the product with a heating iron such as an electric iron.

Conductive GASKET, which has left and right (surface) energization and up and down conduction, has a buffering property that can be used as a substitute for the existing gasket without changing the structure of the device. Wireless communication terminals, computers, monitors, microwave ovens, home appliances, game consoles, sound If it is applied to a device such as GASKET and replaced, it can maintain the buffering function and improve the electricity flow. It prevents the circuit interference inside the device caused by static electricity or electromagnetic waves, thereby stabilizing the device electrically and greatly reducing the risk of static electricity or electromagnetic waves on the user's human body. It can be alleviated and its performance will be more excellent if it is electrically grounded around.

Especially for C-microphone gasket, buzzer gasket, microspeaker & receiver gasket used in wireless communication terminal, computer, monitor, microwave, etc. Application to gasket not only stabilizes and improves the mechanical performance of the equipment, but also greatly reduces the risk of static electricity and electromagnetic waves on the human body.
