Wire or sheet metal made of the relatively low metal material of point, it is connected on by protection circuit, the equipment in circuit or circuit
When overloading or breaking down, molten part generates heat and melted, and so as to cut off circuit, reaches the purpose of protection circuit or equipment.It is known
In outdoor high-voltage fuse, overcoat is the insulator of ceramic material, and the protection original paper such as fusion tube, contact is all placed in into ceramic insulation
It is sub internal, while be bonded at the line outlet of cable using injection molded elastomer on insulator form totally-enclosed insulated enclosure protection up and down,
The effect such as dust-proof, antifouling, anti-corrosion, antifog, anti-icing can be played.And almost all of fuse uses in the market
It is ceramic coat, this overcoat weight is larger, installs and uses and follow-up detachable maintaining is inconvenient；In addition, ceramic material is hard
Degree is high, and at some aperture positions, its sealed connection between the component of quality of rubber materials is poor.
Utility model content
In order to solve the above problems, the purpose of this utility model is to propose a kind of cast for outdoor closed fuse
Formula insulating coating, the overcoat of traditional ceramic material is changed into the silicon rubber pipe sleeve of erosion resisting insulation, while in silicone rubber tube
The resin lining that moulding by casting high rigidity insulate in set, significantly reduces the overall weight of fuse overcoat, and improve
The sealing property of opening.
The utility model is for the taken technical scheme that solves the above problems：One kind is used for outdoor closed fuse
Cast-type insulating coating, the fuse overcoat is by silicon rubber pipe sleeve and the resin for being close to silicon rubber pipe sleeve inwall moulding by casting
Lining integrally connected is formed, and one end of the silicon rubber pipe sleeve and resin lining be cable inlet, the other end be for loading or
The openend of fuse element is taken out, the side-walls of silicon rubber pipe sleeve and resin lining close to bottom offer the cable of through-lumen
Outlet, wherein, cable inlet and cable outlet are sealed to fill out respectively and are provided with into line conductive pole and outlet conductive pole, it is described enter line it is conductive
Post and outlet conductive pole, which are the cable inlet of an external diameter and respective installation place, or cable outlet internal diameter matches cylindric leads
Body, enters at both ends center of the line conductive pole along fuse length direction and outlet conductive pole is along the two of vertical fuse length direction
The screw for installing connecting cable or fuse element is offered at the center of end.
As preferable, the end that the silicon rubber pipe sleeve is located at cable inlet is cast with sealing rubber cap.
As preferable, the end interior edge end circumference that the resin lining is located at openend is hidden and is provided with the first inserts, tree
Fat lining is connected with fuse base by the first inserts.
As preferable, the inwall in the resin lining cylinder at outlet conductive pole is set along fuse length direction
It is equipped with the second inserts for installing fixed fuse element.
Compared with prior art, the utility model has the advantages that：
A kind of cast-type insulating coating for outdoor closed fuse described in the utility model, different from traditional
Using ceramic material as fuse overcoat, but use anticorrosive anti-wear and insulation, silicone rubber material in light weight work
For fuse overcoat, while the resin lining of cast high rigidity insulation is integrally formed in silicon rubber pipe sleeve, resin lining makes up
Silicone rubber tube is enclosed on the deficiency of component installation process hardness, dedicated for the installation connection fusing component in overcoat, two
Person combines, and significantly reduces the overall weight of fuse overcoat, and picture cable inlet in overcoat, cable outlet etc. are multiple
Opening, then when being sealed using sealing rubber cap, it is directly combined with silicone rubber seal, sealing effectiveness more preferably, improves
The sealing property of opening.
