Abstract

The utility model discloses a card holder for a fuse tube. The card holder comprises a base and a metal pull ring hinged with a side surface of the base. The base comprises a base body and a hard insulation cover body buckled with the base body; the base body is a cone; the periphery of the base body is provided with an insulation layer; the insulation layer is made of a soft epoxy resin layer; the base body is provided with an insert core therein; the insert core is vertically disposed at the center of the base body and extends to the outer side of the base body; the insert core is further provided with an extension part disposed out of the base body; the periphery of the extension part is provided with a circular fin set; and a circular clamping jaw set is disposed out of the hard insulation ring. The soft insulation layer is designed at the periphery of the base body. The insulation layer plays relatively good insulation effect while realizing a seal effect of the connecting part between card holder and the fuse tube, and thus oil seal originally disposed below the base body is improved into the insulation member seal; and phenomena of poor insulation effect and even no insulation caused by oil leakage can be effectively prevented.
