Moreover, the conductive foam may be classified into a general conductive foam, a nickel-plated copper conductive foam, a gold-plated conductive foam, a carbon-plated conductive foam, a tin-plated conductive foam, a conductive aluminum foil foam, a conductive copper foil foam, an omni-directional conductive foam, an SMT conductive foam, an I/O conductive foam pad, and the like.

However, the device is only suitable for effectively avoiding the breakage of the conductive cotton, prolonging the service life of the conductive cotton, and can not solve the problems of insufficient protection and internal strength of the outer side of the conductive cotton.

The outside of current two-sided conductive cotton, when being connected with equipment electrical components, the circumstances of wearing and tearing fish tail appears easily to the side, lacks better protection architecture, influences the life of two-sided conductive film, and moreover, the inside of conductive cotton lacks better enhancement protection, and intensity is not enough, and does not possess waterproof and fireproof function, influences the use of two-sided conductive cotton.
