Abstract
The utility model relates to a fuse, comprising an inner core, a fuse wire, leads, a base body, baffles, and a casing. A surface of the inner core is fixed with the fuse wire, and the inner core is connected with the leads. The base body is molded on the two leads as a whole through injection molding. Through the injection molding, an upper edge of the base body is connected with four baffles which are perpendicular to the base body. The casing covers on the base body which is inlaid with the inner core and the baffles. Edges of the baffles are arc-shaped, and the baffles are uniformly and correspondingly disposed on four sides of the inner core and are higher than the fuse wire. When the fuse is disconnected to perform protection, most generated arcs strike on the four baffles to disperse energy, so that the casing is not easy to melt or damage, and potential safety hazard of the fuse is reduced.
Description
Technical field
The utility model relates to a kind of fuse, the low fuse of particularly a kind of potential safety hazard.
Background technology
Fuse is a kind of application electric elements very widely in daily commercial production and life, is mainly used in the protective circuit safe operation.Fuse is using when breaking off safeguard protection, and the electric arc that the moment that fuse breaks off produces can directly hit on shell, causes shell to fuse easily or impacts and cause some security incidents.
The utility model content
The utility model provides a kind of fail safe higher fuse to the deficiency of prior art.
The utility model is realized through following technical scheme:
A kind of fuse; Comprise inner core, fuse, lead, pedestal, baffle plate and shell, it is characterized in that: the intrinsic fuse of said core surface, inner core connects lead; Said pedestal is molded on two leads through integrated through injection molding; The pedestal upper end-face edge is connected with four baffle plates that are vertically to pedestal through injection moulding, and the height of this baffle plate is higher than fuse, and said shell covers on the pedestal that studs with inner core and baffle plate.
Further, the profile of said pedestal is the different oblate cylinder center stack shapes of two diameters.
Further, said baffle plate is a kind of baffle plate of processing with the PA46 material with resistance to elevated temperatures.
Further, the edge of said baffle sidewall is an arc.
Further, said baffle plate evenly is located at four sides of inner core accordingly.
Further, said shell is cylindric.
Further, the interior diameter of said shell equates with the maximum gauge of pedestal.
The beneficial effect of the utility model is: when fuse broke off protection, the electric arc major part of being sent can be hit on four baffle plates and energy is disperseed, and shell can not fused or destroy so easily, thereby reduced the potential safety hazard of fuse.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further specified.
Can find out that from Fig. 1 and Fig. 2 a kind of fuse comprises inner core 1, fuse 2, lead 3, pedestal 4, PA46 baffle plate 5 and shell 6; Said inner core 1 surperficial intrinsic fuse 2; Inner core 1 connects lead 3, and said pedestal 4 is molded on two leads 3 through integrated through injection molding, and pedestal 4 upper end-face edges are connected with four PA46 baffle plates 5 that are vertically to pedestal 4 through injection moulding; Sidewall 7 edges of PA46 baffle plate 5 are arc and four sides that evenly are located at inner core 1 accordingly; The height of PA46 baffle plate 5 is higher than fuse 2, and the interior diameter of said shell 6 equates that with the maximum gauge of pedestal 4 shell 6 covers on the pedestal 4 that studs with inner core 1 and PA46 baffle plate 5.
When fuse broke off protection, nationality was by PA46 baffle plate 5, and the electric arc major part of being sent can be hit on four PA46 baffle plates 5 and energy is disperseed, and shell 6 can not fused or destroy so easily, thereby reduced the potential safety hazard of fuse.
Below the utility model is done a detailed description, but obvious, those skilled in the art can carry out various changes and improvement, and the scope of the utility model that does not deviate from appended claims and limited.
Claims (7)
1. fuse; Comprise inner core, fuse, lead, pedestal, baffle plate and shell, it is characterized in that: the intrinsic fuse of said core surface, inner core connects lead; Said pedestal is molded on two leads through integrated through injection molding; The pedestal upper end-face edge is connected with four baffle plates that are vertically to pedestal through injection moulding, and the height of this baffle plate is higher than fuse, and said shell covers on the pedestal that studs with inner core and baffle plate.
2. a kind of fuse according to claim 1 is characterized in that: the profile of said pedestal is the different oblate cylinder center stack shapes of two diameters.
