Description
Technical field
Electric fittings field is the utility model is related to, especially a kind of DC fuse switch.
Background technology
DC fuse is mainly partly made of melt and fusion tube and outer filled wait.In use, fuse is connected
In by protection circuit, when exceeding setting by the electric current of protection circuit, and by after a certain period of time, being produced by melt itself
Heat fusing melt, disconnects circuit, so as to play the role of protection.The electricity of disjunction circuit using metallic conductor as melt
Device, is series in circuit, and when overloading or short circuit current flow passes through melt, melt itself will generate heat and fuse, so as to power train
System, various electrical equipments and household electrical appliance all play certain protective effect, present DC fuse conventional unipolar
18mm wide fuse bases fill the protection of fusible core, direct current install and use the space accounted for it is big, to photovoltaic generating system electricity consumption, distribution
Installation practicality is not high, cannot increasingly meet the requirement that some distribution are installed and used, and solidus is cumbersome.
Utility model content
The purpose of this utility model is to solve defect existing in the prior art, there is provided a kind of DC fuse switch.
To achieve these goals, the technical solution adopted in the utility model is：
A kind of DC fuse switch, including fuse base more than a pole or a pole, fuse base are equipped with one
A or more than one fusible core, the fuse base are equipped with solidus mechanism corresponding with fusible core, and solidus mechanism includes setting
Installation passage on fuse base, is equipped with multiple fixed plates in installation passage, and the end of fixed plate is equipped with groove, in groove
Spring, the end connection arc clamp of spring are installed, arc clamp includes insertion end and fastening end, insertion end and fastening end
Between connected by inclined support surface, the inclined support surface of multiple arcs clamp surrounds wiring hole.
A kind of above-mentioned DC fuse switch, multiple fixed plates are uniformly arranged on installation passage inner wall.
A kind of above-mentioned DC fuse switch, the fuse base four corners are equipped with fixing bolt.
A kind of above-mentioned DC fuse switch, multiple fusible cores are set up in parallel on fuse base.
A kind of above-mentioned DC fuse switch, the width of single pole cut out base is 18mm.
A kind of above-mentioned DC fuse switch, the two poles of the earth fuse base are welded by rivet.
The beneficial effects of the utility model are：The single pole cut out base of the fuse switch be equipped with one or one with
On fusible core, contour structures compact, can reduce lateral dimension installation site, reduce box sizes, reduce babinet cost；
Reduce accessory, 2 pole fuse bases need not be equipped with, rivet welds, reduced production technology, reduced production cost, improve production
Efficiency.

Embodiment
As shown in Figures 1 to 4, a kind of DC fuse switch, including fuse base 1 more than a pole or a pole, melt
Disconnected device base 1 is equipped with one or more fusible core 2, and fuse base 1 is equipped with solidus mechanism corresponding with fusible core 2,
Solidus mechanism includes the installation passage 3 being arranged on fuse base 1, and multiple fixed plates 4, fixed plate 4 are equipped with installation passage 3
End be equipped with groove 5, installation spring 6 in groove 5, the end connection arc clamp 7 of spring 6, arc clamp 7 includes inserting
Enter end 71 and fastening end 72, connected between insertion end 71 and fastening end 72 by inclined support surface 73, multiple arcs clamp 7
Inclined support surface 73 surrounds wiring hole 74, and the aperture that multiple fastening ends 72 surround hole is less than the hole that multiple insertion ends 71 surround hole
Footpath, when electric wire accesses, the end of electric wire is inserted into wiring hole 74 from the insertion end 71 of arc clamp 7, and electric wire is with tilting branch
Support face 73 contacts and extrudes the fastening end 72 of arc clamp 7, so as to compress spring 6, fastening end 72 is acted in the elastic force of spring
Lower clamping electric wire, effectively prevents electric wire from loosening, and is inserted directly into electric wire and can fix electric wire, and electric wire is easy for installation.
In the utility model, multiple fixed plates 4 are uniformly arranged on 3 inner wall of installation passage, and 1 four corners of fuse base are set
There is fixing bolt 11, multiple fusible cores 2 are set up in parallel on fuse base 1, and the width of single pole cut out base 1 is 18mm, and two
Pole fuse base 2 is welded by rivet.
The single pole cut out base of the fuse switch is equipped with one or more fusible core, and contour structures are compact tight
Gather, lateral dimension installation site can be reduced, reduce box sizes, reduce babinet cost；Reduce accessory, 2 pole fuse bases
It need not be equipped with, rivet welds, reduces production technology, reduces production cost, improves production efficiency.
The advantages of basic principle, main feature and the utility model of the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
