Description
Technical field
This utility model belongs to fuse technologies field, is specifically related to a kind of sealing tubular fuse.
Background technology
Fuse refers to when electric current exceedes setting, makes melt fuse with the heat that itself produces, the one of disconnecting circuit
Kind of electrical equipment, fuse be exceed setting a period of time according to electric current after, make Melt molten with the heat that himself produces, thus
Circuit is made to disconnect；Use a kind of current protector that this principle is made, fuse be widely used in high and low voltage electric distribution system and
In control system and electrical equipment, as short circuit and the protector of overcurrent, it is to apply one of most common protection device.
Metallic conductor is utilized to be series in circuit as melt, when overload or short circuit current are by melt, because of himself
Heating and fuse, thus a kind of electrical equipment of disjunction circuit, fuse structure is simple, easy to use, is widely used in power system, each
Planting as protection device in electrical equipment and household electrical appliance, fuse is mainly made up of, wherein melt, shell and bearing 3 part
Melt is the key element controlling operating chacteristics, and the material of melt, size and dimension determine operating chacteristics, and melt material is divided into
Low melting point and high-melting-point two class, low melting material such as lead and metal, the low easy fusing of its fusing point, owing to its resistivity is relatively big,
Therefore make the sectional dimension of melt relatively greatly, the metal vapors produced during fusing is more, is only applicable to the fuse of low breaking capacity,
Materials with high melting point such as copper, silver, its fusing point is high, it is not easy to fusing, but owing to its resistivity is relatively low, can be made into than low fusing point melt relatively
Little sectional dimension, the metal vapors produced during fusing is few, it is adaptable to the fuse of high breaking capacity, the shape of melt is divided into silk
Shape and banding two kinds, the shape changing cross section can significantly change the operating chacteristics of fuse, and fuse has various different fusing
Characteristic curve, goes for the needs of dissimilar protection object.
Existing sealing tubular fuse nut and outside are provided with waterproof washer and seal, and waterproof washer is using
In the most aging, nut the most easily loosens.
Utility model content
This utility model purpose is to provide a kind of sealing tubular fuse, including insulating cylinder, copper cap, slotting tool and melt, institute
Stating copper cap and be fixed on the both sides of insulating cylinder, insulating cylinder both sides are provided with slotting tool, and slotting tool to the internal extension of insulating cylinder and is connected with melt
Fixing, with jagged sealing mechanism on described copper cap, and there is sealing bearing in the connection side pressure envelope of copper cap with insulating cylinder；
Arranging non-conductive fibre cloth in insulating cylinder, non-conductive fibre cloth one end is bonded on the inwall of insulating cylinder, and one end is solid with melt bonding
Fixed.
Further, the two ends, left and right of described melt are respectively arranged with U-lag mouth, and screw is solid by melt by U-lag mouth
It is scheduled on slotting tool.
Further, described slotting tool being fixed with socket, socket is provided with binding post.
Further, described non-conductive fibre cloth can substitute with nylon cloth.
The beneficial effects of the utility model are:
1, simple in construction of the present utility model, is provided with two-layer and seals, good seal performance；
2, use fiber cloth to fix melt so that melt is flexible fixing in insulation tube, reduce in transit to melt
Infringement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, title and the mark of all parts are as follows:
Binding post 1, slotting tool 2, socket 3, copper cap 4, screw 5, melt 6, non-conductive fibre cloth 7, sealing mechanism 8, seal bearing
9, insulating cylinder 10.
Detailed description of the invention
For making technical characteristic of the present utility model, operation principle and beneficial effect it can be readily appreciated that below in conjunction with accompanying drawing and reality
Execute example this utility model is described in further detail, but be not construed as restriction of the present utility model.
With reference to Fig. 1, a kind of sealing tubular fuse, including insulating cylinder 10, copper cap 4, slotting tool 2 and melt 6, described copper cap 4
Being fixed on the both sides of insulating cylinder 10, insulating cylinder 10 both sides are provided with slotting tool 2, and slotting tool 2 to the internal extension of insulating cylinder 10 and connects with melt 6
Connect fixing, with jagged sealing mechanism 8 on described copper cap 4, and connection side pressure Feng Youmi at copper cap 4 with insulating cylinder 10
Envelope bearing 9；Arranging non-conductive fibre cloth 7 in insulating cylinder 10, non-conductive fibre cloth 7 one end is bonded on the inwall of insulating cylinder 10, and one
End is adhesively fixed with melt 6.
The two ends, left and right of described melt 6 are respectively arranged with U-lag mouth, and melt 6 is fixed on slotting by U-lag mouth by screw 5
On cutter 2.
Being fixed with socket 3 on described slotting tool 2, socket 3 is provided with binding post 1.
Described non-conductive fibre cloth 7 can substitute with nylon cloth.
When concrete assembling, by insulating cylinder 10 with in sealing bearing 9 press seal together to copper cap 4, seal bearing 9 for absolutely
The press seal of edge cylinder 10, sealing mechanism 8 is for secondary seal.Use the seal form of this structure, fusing can be effectively reduced
Device in use causes the problem of aging of sealing ring, and the technical program uses press seal one sealing, decreases nut simultaneously
Loosening problem.
Use fiber cloth to fix melt 6 so that melt 6 is flexible fixing in insulation tube 10, reduce in transit to molten
The infringement of body 6.
The above, be only preferred embodiment of the present utility model, not impose any restrictions this utility model, every
Any simple modification, change and equivalent structure change above example made according to this utility model technical spirit, the most still
Belong in the protection domain of technical solutions of the utility model.
