Abstract
The utility model discloses a kind of fuse-link, its drip irrigation device comprises fusion tube, be located at the fuse in fusion tube and be located at the enclosing cover at fusion tube two ends respectively, the outer wall place, two ends of described fusion tube is respectively equipped with ring recess, described enclosing cover comprises socket part and riveting portion, described socket part is sheathed on the end of fusion tube, described riveting portion is integrated with socket part and is connected, and described riveting portion riveting enters in ring recess corresponding to this end of fusion tube.It can realize enclosing cover and the effective of fusion tube fixes, and not easily loosens, comes off, and improves stability in use and the breaking capacity of fuse-link, ensures that fuse-link still can be in long-term high-quality, normal operating state under extreme, severe condition.
Description
Technical field
The utility model relates to a kind of circuit protection electric component, and more particularly it relates to a kind of fuse-link.
Background technology
Fuse-link is commonly called as " fuse ", is apply electronic component very widely in power equipment, plays a part very large in the safe operation of circuit.Fuse-link on market is generally made up of fusion tube, fuse and enclosing cover, is stamped electric conducting material outward and makes, and fuse is placed in melt, and two ends are connected to enclosing cover, fills arc-extinguishing medium in fusion tube.
Authorization Notice No. is that the Chinese patent document of CN203398066U discloses a kind of photovoltaic system protection fuse blows body; comprise fusion tube, be located at the fuse in fusion tube and be located at the enclosing cover at fusion tube two ends respectively; it is characterized in that: described fusion tube two ends are respectively equipped with head protector; head protector is between fusion tube and enclosing cover; described head protector is provided with the through hole with fusion tube conducting, and the opposite side of the corresponding enclosing cover of through hole is provided with the insulation board that can puncture.Existing fuse-link structure is many and above-mentioned similar, its two ends are enclosing cover, be placed on the two ends of fusion tube, inner connection fuse, enclosing cover is and is directly placed on fusion tube, and fusion tube is cylindrical tube, what enclosing cover of the prior art and fusion tube only adopted is the mode be directly socketed, although process more convenient, but because enclosing cover lacks effective fixation, connect effect defective tightness, enclosing cover easily exists loosening, or fixing problem not in place, thus will the stability of the element uses such as fusion tube internal fuse be had influence on, as enclosing cover loosens, cause inner arc-extinguishing medium leakage etc., enclosing cover is for ensureing that fuse-link can be in high-quality for a long time, the guarantee of normal operating state, therefore guarantee that enclosing cover is in the stability that effective fixation uses fuse-link very important.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of fuse-link, it can realize enclosing cover and the effective of fusion tube fixes, not easily loosen, come off, improve the stability in use of fuse-link, ensure that fuse-link still can be in long-term high-quality, normal operating state under extreme, severe condition.
For achieving the above object, the utility model provides following technical scheme: a kind of fuse-link, comprise fusion tube, be located at the fuse in fusion tube and be located at the enclosing cover at fusion tube two ends respectively, the outer wall place, two ends of described fusion tube is respectively equipped with ring recess, described enclosing cover comprises socket part and riveting portion, described socket part is sheathed on the end of fusion tube, and described riveting portion is integrated with socket part and is connected, and described riveting portion riveting enters in ring recess corresponding to this end of fusion tube.
Described fusion tube is organic material pipe.
By adopting technique scheme, abandon on the basis of the mode that traditional fuse-link enclosing cover and fusion tube are directly socketed, by being respectively provided with ring recess in fusion tube two ends, make to form certain stagger ratio between ring recess bottom surface and the sidewall surfaces of fusion tube, be equipped with a riveting portion, its socket part and traditional outer cover structure similar, riveting portion is shaped in the opening part of socket part, and when enclosing cover is placed on fusion tube one end, riveting portion can be used for riveting and enters in ring recess, make also to form certain stagger ratio between riveting portion and socket part, thus enclosing cover is fixed on fusion tube closely, by this technical scheme, make the enclosing cover fixed effect fixed more reliable, not easily loosen, come off, cannot deviate to both sides, the stability that effective raising fuse-link uses, better to adapt to the use under mal-condition.And fusion tube is organic material pipe, convenient production and processing fusion tube profile, its material itself has good toughness and intensity.When fuse big current disjunction fusion tube inside produces huge pressure, enough toughness and intensity can be had to bear and offset this pressure, be unlikely to fusion tube and burst.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model fuse-link embodiment;
Fig. 2 is the structural representation of the utility model fuse-link embodiment fusion tube.
Description of reference numerals: 1, fusion tube; 2, enclosing cover; 11, ring recess; 21, socket part; 22, riveting portion.
Embodiment
Referring to figs. 1 through Fig. 2, the utility model fuse-link embodiment is described further.
As shown in Figure 1, fuse-link described in the present embodiment, comprise fusion tube 1, be located at the fuse in fusion tube 1 and be located at the enclosing cover 2 at fusion tube 1 two ends respectively, the outer wall place, two ends of described fusion tube 1 is respectively equipped with ring recess 11, ring recess 11 is annular, described enclosing cover 2 comprises socket part 21 and riveting portion 22, described socket part 21 is sheathed on the end of fusion tube 1, described riveting portion 22 is integrated with socket part 21 and is connected, described riveting portion 22 riveting enters in ring recess 11 corresponding to this end of fusion tube 1, and described fusion tube 1 can adopt pmma material to make.
This programme has abandoned the mode that traditional fuse-link enclosing cover 2 is directly socketed with fusion tube 1, by being respectively provided with ring recess 11 in fusion tube 1 two ends, make between the sidewall surfaces of ring recess 11 bottom surface and fusion tube 1, to form certain stagger ratio (i.e. difference of height), enclosing cover 2 also abandons the structure of cylindrical cap in the past simultaneously, be equipped with a riveting portion 22, its socket part 21 and traditional enclosing cover 2 similar, riveting portion 22 is shaped in the opening part of socket part 21, and when enclosing cover 2 is placed on fusion tube 1 one end, riveting portion 22 is for being positioned at above ring recess 11, by riveting portion 22 riveting is entered in ring recess 11, make also to form certain stagger ratio between riveting portion 22 and socket part 21, thus make enclosing cover 2 be fixed on fusion tube 1 closely, by this technical scheme, make enclosing cover 2 fixed effect fixed more reliable, not easily loosen, come off, cannot deviate to both sides, the structure in ring recess 11 is entered by riveting portion 22 riveting, snap-in force is produced bottom riveting portion 22 and ring recess 11, it is made to be difficult to rotate, fixed effect is reliable, the stability that effective raising fuse-link uses, better to adapt to the use under mal-condition.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, all within design concept of the present utility model, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
