Abstract
The utility model discloses caps outside a kind of fuse, including fusion tube, are arranged on the inner ring at fusion tube both ends and are arranged on fusion tube both ends and cover the cap of inner ring, and cap shape is not fixed, and have round, rectangular etc., and the outer wall of cap is equipped with concave point.Thus the outer cap of fuse designed can effectively increase the binding force with fuse base by concave point.
Description
Technical field
The utility model is related to fuse technologies fields, are especially a kind of outer cap of fuse.
Background technology
Fuse refers to when electric current is more than specified value, melt is made to fuse with the heat that itself is generated, the one of disconnecting circuit
Kind electric appliance.Fuse be according to electric current be more than specified value for a period of time after, with its own generation heat make Melt molten, so as to
Disconnect circuit；With current protector a kind of made of this principle.Fuse be widely used in high and low voltage electric distribution system and
It is using one of most common protection device as short circuit and the protector of overcurrent in control system and electrical equipment.
The outer cap of fuse is also known as fuse-link, and the outer cap of fuse of the prior art has the following problems in use：
The outer cap of the outer cap of fuse is susceptible to when being installed with fuse base to be occurred with reference to undesirable situation；There is fuse in fusion tube, melt
It manages as single layer structure, service life is low, and arc quenching effect is poor, and in order to improve the arc quenching effect of fusion tube, some producers can be by fusion tube system
Into multiple tube, the service life and arc quenching effect of fusion tube can be increased, but this multiple tube involves great expense, and can improve and be produced into
This.
Utility model content
In view of the defects of above-mentioned prior art, the purpose of this utility model is that：There is provided a kind of fuse outer cap, Neng Gouti
The high binding force with fuse base, and manufacture at low cost.
The technical solution of the utility model is：The outer cap of fuse, including fusion tube, be arranged on the inner ring at fusion tube both ends with
And be arranged on fusion tube both ends and cover the cap of inner ring, the outer wall of the cap is equipped with concave point.
Further, the quantity of the concave point is one or more.
Further, the highland barley paper tube that can be taken out, geomery and the fusion tube phase of the highland barley paper tube are equipped in fusion tube
Match.
Further, the both ends of the fusion tube have opening, and the taking-up of highland barley paper tube refers to that the highland barley paper tube and tube body are removable
Formula connects.
Further, the removable connection refers to the removable company of opening of the opening and fusion tube of highland barley paper tube
It connects.
Further, the highland barley paper tube is inserted into from the opening of fusion tube and is accommodated in fusion tube, and highland barley paper tube is outer
Wall is bonded with fusion tube inner wall.
Using cap outside fuse provided by the utility model, advantage is：The outer wall of cap is equipped with concave point, recessed
Point facilitates cap to be combined with fuse base；Highland barley paper tube it is cheap and wear-resisting ageing-resistant, arc-extinguishing tube can be improved
Service life, also with arc quenching effect, and highland barley paper tube is replaced conveniently.

Fig. 2 is the decomposition diagram of the utility model；
Fig. 3 is the structure diagram when fusion tube of the utility model is installed with highland barley paper tube；
The fusion tube and the structure diagram after the installation of highland barley paper tube that Fig. 4 is the utility model.
Shown in figure：1-fusion tube, 2-inner ring, 3-cap, 4-concave point, 5-highland barley paper tube.
Specific embodiment
For it is relatively intuitive, be fully understood by the technical solution of the utility model, now just combine the progress of the utility model attached drawing
Unrestricted feature description is as follows：
As shown in Fig. 1-Fig. 4, the outer cap of fuse including fusion tube 1, is arranged on the inner ring 2 at 1 both ends of fusion tube and is arranged on
1 both ends of fusion tube and the cap 3 for covering inner ring 2, the outer wall of cap 3 are equipped with concave point 4.
The quantity of concave point 4 is one or more.3 shape of cap is not fixed, and has round, rectangular etc..
The highland barley paper tube 5 that can be taken out is equipped in fusion tube 1, geomery and the fusion tube 1 of highland barley paper tube 5 match.
The both ends of fusion tube 1 have opening, and highland barley paper tube 5, which can take out, refers to the highland barley paper tube 5 and the removable connection of tube body
The removable removable connection of opening for connecting the opening and fusion tube 1 that refer to highland barley paper tube 5.
The opening of highland barley paper tube 5 from fusion tube 1 is inserted into and is accommodated in fusion tube 1, and the outer wall of highland barley paper tube 5 and fusion tube 1
Inner wall is bonded.During assembling, first one end of highland barley paper tube 5 is inserted into fusion tube 1, until highland barley paper tube, 5 whole are inserted into fusion tube 1.
The outer wall of the outer cap cap 3 of fuse provided by the utility model is equipped with concave point 4, and concave point 4 facilitates cap 3 with melting
Disconnected device pedestal combines；Highland barley paper tube 5 it is cheap and wear-resisting ageing-resistant, the service life of arc-extinguishing tube can be improved, also had
There is arc quenching effect, and highland barley paper tube 5 is replaced conveniently.
Certainly, the above is only the preferred embodiments of the present utility model only, and therefore, it does not limit the patents of the utility model
Range, all with the utility model specification and schema content institute, simply modification and equivalent structure change for it, should all similarly wrap
Within scope of patent protection contained in the utility model.
