Abstract
The invention discloses a fuse-combined type surge protector. The fuse-combined type surge protector comprises a protector body. An overcurrent protection circuit is arranged inside the protector body. At least one backup protection element is connected to the overcurrent protection circuit in series. The protector body comprises a shell. A fuse is connected to the overcurrent protection circuit inside the shell in series and fixedly arranged in a fuse fixing basket groove formed inside the shell. A cover plate is arranged at a groove opening part of the fuse fixing basket groove. The fuse is sealed in the fuse fixing basket groove. One end of the fuse is electrically connected with a discharge electrode on a first binding post at one end inside the shell through a flat and straight connection copper piece. A second binding post at the other end inside the shell is electrically connected with a piezoresistor inside a cavity in the middle of the shell through an L-shaped connection copper piece. According to the fuse-combined type surge protector, the fuse is good in explosion-proof performance, the installed protective basket groove is good in sealing performance, the level of safety performance in use is high, the two ends of the fuse and the binding posts are electrically connected through flat and straight copper pieces, resistance is low, and residues of residual voltage are reduced.
Description
Technical field
The present invention relates to surge protector technical field, be specifically related to a kind of fused combination type surge protector.
Background technology
Under prior art, the fuse of common protector is arranged on outside, is unfavorable for explosion-proofly, is exposed to outside safe not, and fuse two ends connect and easily produced inductance by tortuous wire, or causes residual voltage to be detained, and affects vent discharge effect.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of fused combination type surge protector.
To achieve these goals, the technical solution adopted for the present invention to solve the technical problems is: a kind of fused combination type surge protector, comprise protector body, in protector body, be provided with current foldback circuit and heavy current impact pressure limited protection circuit, described current foldback circuit is at least serially connected with a backup protection element, described heavy current impact pressure limited protection circuit comprises the series circuit that at least one piezo-resistance and a backup protection element form, described protector body comprises shell, on the current foldback circuit of enclosure, be serially connected with a fuse, fuse is fixedly installed in the fixing basket of the fuse groove that enclosure offers, the notch of the fixing basket of described fuse groove is provided with cover plate, fuse is enclosed in the fixing basket of fuse groove, one end of fuse is electrically connected to the sparking electrode being arranged on first binding post of enclosure one end by straight connection copper part, the second binding post that is arranged at the enclosure other end connects copper part by L-type and is electrically connected to the piezo-resistance that is arranged on shell middle part inner chamber.
Furtherly, the fixing basket of a described fuse groove is rectangle or half of cylindrical plastic basket groove, and described plastic crate groove and shell be structure as a whole, and described cover plate is and the corresponding identical dull and stereotyped cover plate of above-mentioned plastic crate groove notch.
Furtherly, be connected copper part with L-type be generous copper sheet to described straight connection copper part.
Beneficial effect of the present invention: fuse explosion-proof performance of the present invention is good, installs a protection basket groove good leak tightness, and usage safety performance grade is high, and when piezo-resistance punctures, circuit produces power current, and fuse can quick-break, makes protector safe escape circuit.Fuse two ends and binding post adopt straight copper sheet to be electrically connected to, and resistance is little, reduce residual voltage residual.
Accompanying drawing explanation
Fig. 1 is the structural representation of watching attentively of the present invention;
Fig. 2 is internal structure schematic diagram of the present invention.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
A kind of fused combination type surge protector as depicted in figs. 1 and 2, comprise protector body 1, in protector body 1, be provided with current foldback circuit and heavy current impact pressure limited protection circuit, described current foldback circuit is at least serially connected with a backup protection element, described heavy current impact pressure limited protection circuit comprises the series circuit that at least one piezo-resistance and a backup protection element form, described protector body 1 comprises shell 2, on the current foldback circuit of shell 2 inside, be serially connected with a fuse 3, fuse 3 is fixedly installed in the fixing basket of the fuse groove 4 of offering shell 2 inside, the notch of the fixing basket of described fuse groove 4 is provided with cover plate, fuse is enclosed in the fixing basket of fuse groove 4, one end of fuse 3 is electrically connected to the sparking electrode 6 being arranged on first binding post 5 of shell 2 inner one end by straight connection copper part 7, the second binding post 5 that is arranged at the shell 2 inner other ends connects copper part 8 by L-type and is electrically connected to the piezo-resistance 9 that is arranged on shell 2 middle part inner chambers.
Preferably, the fixing basket of a described fuse groove 4 is rectangle or half of cylindrical plastic basket groove, and described plastic crate groove and shell 2 be structure as a whole, and described cover plate is and the corresponding identical dull and stereotyped cover plate of above-mentioned plastic crate groove notch.
Preferably, described straight connection copper part 7 is connected copper part 8 for generous copper sheet with L-type.
Compared with prior art; residual voltage of the present invention reduces more than 50%; owing to installing separately fuse additional; at fuse itself, and on connection wire all there is inductance, certainly exist so very large residual voltage, and adopt after fused combination type surge protector of the present invention; this part residual voltage is almost nil; while cutting off the electricity supply, can eliminate electric arc, reliable advantage, can effectively protect equipment more.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and in the situation that not deviating from spirit of the present invention or essential characteristic, can realize the present invention with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present invention is limited by claims rather than above-mentioned explanation, is therefore intended to include in the present invention dropping on the implication that is equal to important document of claim and all changes in scope.
In addition, be to be understood that, although this specification is described according to execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should make specification as a whole, and the technical scheme in each embodiment also can, through appropriately combined, form other execution modes that it will be appreciated by those skilled in the art that.
