The wiring part of the built-in outdoor fuse under current techniques is set to bolt arrangement and insulating case sub-connection conventionally, but be subject to for a long time the impact of the adverse circumstances such as typhoon, heavy rain, dust, unavoidably can be from the threaded portion of the bolt inner defective insulation that forms of insulation cover that seeps water, cause potential safety hazard, and long-term exposed bolt connector under adverse circumstances is also easily corroded the problem such as get rusty.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of waterproof outdoor fuse, it can effectively solve the outdoor fuse of prior art and be subject to for a long time the impact of the adverse circumstances such as typhoon, heavy rain, dust, can assign to the inner defective insulation that forms of insulation cover from the threaded portion water leaking-in of bolt unavoidably, cause potential safety hazard, and long-term exposed bolt connector under adverse circumstances is also easily corroded the problem such as get rusty.
For achieving the above object, the utility model provides following technical scheme:
The outdoor fuse of a kind of waterproof, comprise insulation cover, in described insulation cover, be provided with high-tension fuse, the upper end of described insulation cover is connected with mounting cover, described mounting cover is connected with bolt connector, the bottom of described bolt connector is connected to one end of high-tension fuse, described mounting cover is connected with insulation rain cover, the other end of the relative mounting cover of described insulation rain cover is circular arc top cover, the wall of the insulation rain cover between described mounting cover link and circular arc top cover is conical walls, the large end of described conical walls is connected with circular arc top cover, the small end of described conical walls is connected with adapter sleeve, described adapter sleeve is connected with mounting cover, described conical walls is provided with hole slot, described hole slot is provided with rubber ring, described rubber ring is provided with through wires hole.
By adopting technique scheme, making screwed joint be insulated rain cover completely protects inside, avoid screwed joint for a long time at storm wind, heavy rain, under the adverse circumstances such as dust, be corroded, and infiltration, smooth camber line by circular arc top cover is excessive, making to insulate the top of rain cover can ponding and be not easy dust, greatly increase the useful life of insulation rain cover, by being arranged on the rubber ring on the hole slot in conical walls, can make electric wire pass the through wires hole on rubber ring, due to the good springiness of rubber, electric wire can pass rubber ring by extruding through wires hole, thereby make rubber ring seal up electric wire completely, the hidden danger of having avoided rainwater to enter insulation rain cover from through wires hole, by the conical walls of back taper, strengthen further again the waterproof ability of through wires hole.
The utility model is further set to: it is characterized in that, described insulation rain cover and mounting cover are directly provided with the first sealing ring.
By adopting technique scheme, by the first sealing ring, avoid water to enter the hidden danger in insulation rain cover from the junction between insulation rain cover and mounting cover, greatly increase the sealing property of insulation rain cover and mounting cover.
The utility model is further set to: between described mounting cover and insulation cover, be provided with the second sealing ring.
By adopting technique scheme, by the second sealing ring, the hidden danger of having avoided water to enter insulation cover inside from the junction between insulation cover and mounting cover, has increased the sealing property of insulation cover and mounting cover greatly.
The utility model is further set to: described insulation cover is provided with projection.
By adopting technique scheme, the projection by insulation on cover, has increased the creepage distance of electric arc on insulation cover greatly, has increased breakdown protection performance, and the volume of the cover that can reduce accordingly to insulate, and reduces cost.
Compared with prior art, the utility model has the advantage of: it is inner and form defective insulation, cause potential safety hazard and the long-term exposed problem such as get rusty that is easily corroded of screwed joint under adverse circumstances from the threaded portion of the bolt insulation cover that seeps water in the impact that is subject to for a long time the adverse circumstances such as typhoon, heavy rain, dust that it can effectively solve the screwed joint of outdoor fuse of prior art.
