  • Patent number: 9341892
    Abstract: The present provides a back plate including a plate and a side wall. The side wall extends out from an edge of the plate, wherein the side wall includes a wall body, a first bending sheet, and a second bending sheet. The first bending sheet is formed by bending outward from a top end of the wall body along a first rotating direction. The second bending sheet is formed by bending an end of the first bending sheet that is away from the top end of the wall body inward along a second rotating direction contrary to the first rotating direction, wherein at least a portion of the second bending sheet overlaps the first bending sheet. The second bending sheet includes a fixing part disposed on a face of the second bending sheet that faces away from the first bending sheet.

  • Patent number: 8173555
    Abstract: The present invention relates to a color-coated fouling-resistant conductive cloth and a manufacturing method thereof. The method includes the steps of providing a conductive cloth interwoven by natural fibers or artificial fibers and containing a metal layer, and forming at least one colored resin-coating layer on the metal layer of the conductive cloth by means of blade coating, wherein the surface of the resin-coating layer does not exceed the intersections of warp yarns and weft yarns of the conductive cloth. The conductive cloth of the present invention has the characteristics of colored appearance, artificial or environmental contamination resistance, and low surface resistance.

  • Publication number: 20090008260
    Abstract: The present invention provides a method for manufacturing embossed conductive cloth, which comprises the steps of (a) providing cloth made of natural fibers or artificial fibers; (b) embossing the cloth to form embossed patterns on it; (c) subjecting the cloth with embossed patterns to a surface roughening treatment while maintaining the embossed patterns on the cloth; and (d) subjecting the surface-roughened cloth to a surface metalizing treatment. The embossed conductive cloth obtained from the method of the present invention has excellent metal adhesion.
