Abstract
The utility model proposes a kind of coaxial fuse cylindrical electric power capacitor, comprise axle center, the first fuse, the second fuse and the 3rd fuse; Described the first fuse, the second fuse and the 3rd fuse length are different, and axle center is identical, from inside outwards coaxially arrange successively; Between described the first fuse, the second fuse, be provided with gap, between the second fuse and the 3rd fuse, be provided with gap.The coaxial fuse cylindrical electric power capacitor of the utility model, improves the radiating effect of electric capacity, saves and produces material, simplifies production technology simultaneously, reduces production costs.
Description
Technical field
The utility model relates to electric capacity field, particularly a kind of coaxial fuse cylindrical electric power capacitor.
Background technology
Cylindrical electric power capacitor fuse diameter of the prior art is large, and radiating effect is poor; Between fuse, connecting lead wire is long, and interior sense, internal resistance are large, and fuse and core group connecting lead wire crosspoint are many, increases insulating material cost and processing cost.
Utility model content
In order to address the above problem, the utility model provides a kind of coaxial fuse cylindrical electric power capacitor, improves the radiating effect of electric capacity, simplifies production technology simultaneously, reduces production costs.Concrete technical scheme is as follows:
Coaxial fuse cylindrical electric power capacitor, comprises axle center, the first fuse, the second fuse and the 3rd fuse; Described the first fuse, the second fuse and the 3rd fuse length are different, and axle center is identical, from inside outwards coaxially arrange successively; Between described the first fuse, the second fuse, be provided with gap, between the second fuse and the 3rd fuse, be provided with gap.
Preferably, the internal diameter of the second fuse is greater than the external diameter of the first fuse.The 3rd fuse internal diameter is greater than the second fuse external diameter.
Preferably, the length of the first fuse, the second fuse and the 3rd fuse one end end face is variant.
Preferably, the length of the first fuse, the second fuse and the 3rd fuse two ends end face is variant.
Preferably, the second fuse is by being welded to connect on the first fuse, and the 3rd fuse is by being welded to connect on the second fuse.
Preferably, the coiling number of turns of the first fuse, the second fuse and the 3rd fuse reduces successively.
The coaxial fuse cylindrical electric power capacitor of the utility model, the first fuse, the second fuse and the 3rd fuse coaxially arrange, and length reduces successively, therefore inner fuse adstante febre can be discharged in time, improve the radiating effect of electric capacity, save and produce material, simplify production technology simultaneously, reduce production costs.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is coaxial fuse cylindrical electric power capacitor cross-sectional view;
Fig. 2 is the identical longitdinal cross-section diagram of coaxial fuse cylindrical electric power capacitor one end length;
Fig. 3 is the different longitdinal cross-section diagram of coaxial fuse cylindrical electric power capacitor two ends length.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, coaxial fuse cylindrical electric power capacitor comprises axle center 1, the first fuse 2, the second fuse 3 and the 3rd fuse 4.Described the first fuse 2, the second fuse 3 are identical with the 3rd fuse 4 axle center, all taking axle center 1 as axle center, reel successively, and the length of the first fuse 2, the second fuse 3 and the 3rd fuse 4 is all different, preferably the length of the first fuse 2, the second fuse 3 and the 3rd fuse 4 reduces successively.Described the first fuse 2, round axle center 1, is wound into a complete circle; The second fuse 3 is reeled around axle center 1, and the second fuse is positioned at the first fuse outside, and leaves certain gap between the first fuse and the second fuse, and the internal diameter of the second fuse is greater than the external diameter of the first fuse.Because the diameter of the second fuse is larger, so the media roll pitch of the laps number of equal length is few compared with the first fuse.The 3rd fuse 4 is reeled around axle center 1, and the 3rd fuse is positioned at the second fuse outside, and leaves certain gap between the second fuse and the 3rd fuse, and the internal diameter of the 3rd fuse is greater than the external diameter of the second fuse.Because the diameter of the 3rd fuse is larger than the second fuse, so the media roll pitch of the laps number of equal length is few compared with the second fuse.Because the coiling number of turns of the second fuse and the 3rd fuse is few, winding efficiency is high, and because the length of the first fuse 2, the second fuse 3 and the 3rd fuse 4 reduces successively, the end face of fuse one or both ends staggers mutually, good heat dissipation effect, as shown in Figures 2 and 3.
Due to the gap of leaving between fuse, and couple together by welding manner two, between fuse, without insulation processing, connecting lead wire is short, and interior sense and internal resistance are little, and dress is saved insulating material and lead material, and joins simply, reduces production costs.
Coaxial fuse cylindrical electric power capacitor of the present utility model, the first fuse 2, the second fuse 3 and the 3rd fuse 4 coaxially arrange, and length reduces successively, improve the radiating effect of electric capacity, save and produce material, simplify production technology simultaneously, reduce production costs.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
