Description
Technical field
The utility model relates to Intelligent fuse technical field, is specially a kind of melt for Intelligent fuse.
Background technology
Intelligent fuse is also referred to as fuse, and it is a kind of installation in circuit, ensures the electric elements that circuit safety runs.Fuse is exactly a kind of short-circuit protector in fact, is widely used in distribution system and control system, mainly carries out short-circuit protection or heavy overload protection.Along with the development of advanced technology, the demand of high-quality fuse is being increased always, melt is as the most important part of fuse, its quality directly decides the quality of Intelligent fuse, in use, there is metal electro-migration phenomenon in the energized state in molten metal, namely the Ion transfer in metal, cavity can be there is in this migration in regional area generation mass defect, or produce quality accumulation and occur hillock or solidify state burr, cause metal defects, cause local overheating, high temperature can accelerate the electromigratory process that metallizes again, defect is increased further, build up and cause melt fusing occurs, have impact on the normal work of melt, melt does not generally all arrange quick-disassembly structure when changing because of melt in the market, change very inconvenient, for above problem, we propose a kind of melt for Intelligent fuse.
Summary of the invention
The purpose of this utility model is to provide a kind of melt for Intelligent fuse, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of melt for Intelligent fuse, comprise main body sheet copper, left hanging head, right hanging head, hexagon through hole, arc-shaped slot and tin coating, the zone line of described main body sheet copper is provided with four lines four row 16 hexagon through holes, the zone line both sides panel of main body sheet copper is evenly provided with the salient point of solid matter, the left and right sides of described main body sheet copper is respectively equipped with left hanging head and right hanging head, the set of described main body sheet copper interposition is provided with tin coating, the both sides of described main body sheet copper are all provided with four arc-shaped slots.
Preferably, described left hanging head and right hanging head are respectively hook structure and lower draw-bar structure, and the hanging head depth of groove of left hanging head and right hanging head is 30mm, connect with the corresponding wiring card on fuse.
Preferably, described left hanging head and right hanging head also can be replaced by the quick-disassembly structure such as link and chuck.
Preferably, the thickness of described tin coating is 0.5-1mm, and area accounts for 2/3rds of main body sheet copper.
Preferably, described main body sheet copper also according to the shape of Intelligent fuse shell, can be set to the sheet copper structure of corresponding various shapes.
Compared with prior art, the beneficial effects of the utility model are: this is used for the melt of Intelligent fuse, the left hanging head adopted, right hanging head and arc-shaped slot make the dismounting of melt convenient, fixing more stable, the hexagon through hole adopted can well be avoided producing quality and piles up and occur hillock or solidify state burr, cause metal defects, the salient point of employing can well be filled up the cavity produced due to metal electro-migration phenomenon around salient point.
Accompanying drawing explanation
Fig. 1 is the utility model vertical view;
Fig. 2 is end view of the present utility model.
In figure: 1 main body sheet copper, 2 left hanging heads, 3 right hanging heads, 4 hexagon through holes, 5 arc-shaped slots, 6 tin coatings and salient point 7.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-2, the utility model provides a kind of technical scheme: a kind of melt for Intelligent fuse, comprise main body sheet copper 1, left hanging head 2, right hanging head 3, hexagon through hole 4, arc-shaped slot 5, tin coating 6 and salient point 7, the zone line of described main body sheet copper 1 is provided with four lines four row 16 hexagon through holes 4, the zone line both sides panel of main body sheet copper 1 is evenly provided with the salient point 7 of solid matter, add man-hour, by carrying out punching press to sheet copper 1, form the salient point 7 of hexagon through hole 4 and solid matter, hexagon through hole 4 well can improve the breaking capacity of melt, arc extinguishing ability and fusing ability, the solution that can also produce metal electro-migration phenomenon flows into hexagon through hole 4 and fills up hexagon through hole 4, can well avoid producing quality pile up and occur hillock or solidify state burr, cause metal defects, salient point 7 can well be filled up the cavity produced due to metal electro-migration phenomenon around salient point 7, the left and right sides of described main body sheet copper 1 is respectively equipped with left hanging head 2 and right hanging head 3, described left hanging head 2 and right hanging head 3 are respectively hook structure and lower draw-bar structure, and the hanging head depth of groove of left hanging head 2 and right hanging head 3 is 30mm, described left hanging head 2 and right hanging head 3 also can be replaced by the quick-disassembly structure such as link and chuck, left hanging head 2 can be connected with the corresponding wiring card on fuse with right hanging head 3, the very enough realizations of this buckle structure are adopted to change melt fast, the set of described main body sheet copper 1 interposition is provided with tin coating 6, the thickness of described tin coating 6 is 0.5-1mm, and area accounts for 2/3rds of main body sheet copper 1, tin coating 6 can be good at preventing main body sheet copper 1 from corroding, the both sides of described main body sheet copper 1 are all provided with four arc-shaped slots 5, arc-shaped slot 5 can realize coordinating with corresponding projection on Intelligent fuse housing, make the fixing more stable of main body sheet copper 1, described main body sheet copper 1 also can according to the shape of Intelligent fuse shell, be set to the sheet copper structure of corresponding various shapes.
