Summary of the invention
In view of the defect of above-mentioned prior art, the purpose of this utility model is: the fuse providing a kind of easy accessibility.
Technical solution of the present utility model is: a kind of fuse of easy accessibility, comprise base, insulator and arc-extinguishing tube, the quantity of described insulator is two, two described insulators are vertically set on the top of base, the two ends of described arc-extinguishing tube are provided with copperhead, the top of described insulator is provided with fixed head, described fixed head top is provided with connecting portion, described connecting portion comprises the two blocks of side plates being welded on fixed head top and the semicircle top sheet being arranged on two pieces of side plate tops, the upper and lower of the inwall of described two blocks of side plates is respectively equipped with the first Access Division and second and meets portion, the copperhead at described arc-extinguishing tube two ends snaps in the first Access Division and second and connects between portion.
Further, described base is by substrate and to be arranged on the side plate of substrate both sides one-body molded, and is provided with the screwed hole of fixed insulation at described substrate two ends, and described substrate middle position is provided with two through holes.
Further, the side of described connecting portion is outwards provided with seat board, and is provided with junction block on described seat board.
Further, described first Access Division and the second Access Division comprise the first elasticity jig arm and the second elasticity jig arm respectively.
Further, the quantity of described first elasticity jig arm and the second elasticity jig arm is respectively two, and two the first elasticity jig arm and two the second elasticity jig arm are symmetricly set on the inwall of two blocks of side plates respectively.
Apply the fuse of a kind of easy accessibility provided by the utility model, its beneficial effect is: connecting portion comprises the two blocks of side plates being welded on fixed head top and the semicircle top sheet being arranged on two pieces of side plate tops, the upper and lower of the inwall of described two blocks of side plates is respectively equipped with the first Access Division and second and meets portion, the copperhead at described arc-extinguishing tube two ends snaps in the first Access Division and second and connects between portion, during installation during arc-extinguishing tube, as long as the copperhead at arc-extinguishing tube two ends is snapped in the first Access Division and second to connect between portion and just arc-extinguishing tube can be fixed, dismounting is all very convenient.
