The utility model content
For this reason, technical problem to be solved in the utility model is that the insulating cylinder of prior art is because the end of the band high-tension electricity that the close fuse in position is set of lid, sealing ring must be set to be prevented creepage, and the sealing ring that brings is in case damaged, just generation is creepage easily, has potential safety hazard and because sealing ring is set, makes the structure of insulating cylinder become complicated, assemble pretty troublesome technical problem, and the insulating cylinder of a kind of difficult generation creepage phenomenon, simple in structure, simple and convenient assembly is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of insulating cylinder comprises
Cylindrical shell and the lid that cooperates with described cylindrical shell;
Electrical fitting is arranged on described cylindrical shell and the described lid, is used for being electrically connected with fuse, other electric elements;
Bindiny mechanism is arranged between described cylindrical shell and the described lid, and described cylindrical shell and described lid are removably connected, and described bindiny mechanism forms connector between described cylindrical shell and described lid;
After described fuse was installed in the described insulating cylinder by described electrical fitting, described connector was positioned at the axial length range of the fusion tube of described fuse.
In the above-mentioned insulating cylinder, described connector the position is set away from metal shell described insulating cylinder, ground connection is installed.
In the above-mentioned insulating cylinder, described connector is positioned at the centre position of described fusion tube.
In the above-mentioned insulating cylinder, described bindiny mechanism is a threaded connection.
Technique scheme of the present utility model has the following advantages compared to existing technology: the 1. insulating cylinder that provides of the utility model, after wherein fuse is installed in the insulating cylinder by electrical fitting, the connector that forms between cylindrical shell and the lid is positioned at the axial length range of the fusion tube of fuse, make the metal connector of connector away from fuse two ends band high pressure, and the fusion tube of close fuse insulation, reduce creepage danger, make the insulating cylinder designs simplification, assemble also very easy, and sealing ring need not be set especially, solved prior art because the sealing ring breakage, cause taking place creepage easily, have the problem of potential safety hazard; 2. the insulating cylinder that provides of the utility model, connector the position is set simultaneously away from metal shell mounting insulation tube, ground connection, near the fusion tube of fuse insulation, reduce the creepage danger of electrified body to metal shell; 3. the insulating cylinder that provides of the utility model, connector is positioned at the centre position of fusion tube, and this position is from two ends that fuse has a high-tension electricity farthest, it is more reasonable to design, and reduces creepage danger, need not sealing ring be set especially and guarantee safety, make the insulating cylinder designs simplification, assemble also very easy; 4. the insulating cylinder that provides of the utility model, bindiny mechanism is a threaded connection, easy accessibility is simple to operate.
