Description
Technical field
It the utility model is related to fuse field, more particularly to a kind of quick fuse surface mounting fuse protector.
Background technology
Electrical equipment can be by internal battery or dispatch from foreign news agency come work.But in the unstable generation overcurrent supply of electric current,
Electrical equipment may be burned out, this key areas as the fields such as Aero-Space or communication be never allow occur, fusing
Device as preventing the overcurrent protection of this kind of phenomenon, to equipment supply rated current more than overcurrent situation
Under, fuse, which will be melted, to break so as to protection equipment, but overcurrent is flashy thing sometimes, if fuse reacts
Overlong time, equipment may be will also result in and be burned out.
Utility model content
Technical problem to be solved in the utility model is to provide simple in construction, small in volume, stable performance, installation
Change a kind of convenient and quick response quick fuse surface mounting fuse protector.
The utility model is to be achieved by the following technical programs：
A kind of quick fuse surface mounting fuse protector, it includes insulating ceramics substrate, coated in ceramic substrate upper surface
The quick fuse layer and the electrode positioned at ceramic substrate both ends in portion, the electrode are interconnected with quick fuse layer, described quick
The top of fuse layer is coated with thermal insulation layer, and heat insulation layer, the quick fuse layer both ends width and pottery are coated above the thermal insulation layer
Ceramic chip width is suitable, middle gradually inwardly to narrow and form the fuse part of one fixed width.
The fusing point of the thermal insulation layer is less than the fusing point of ceramic substrate.
The electrode is the ag material being respectively coated at the both ends of two end faces of ceramic substrate and upper and lower surface.
The beneficial effects of the utility model are：
A kind of quick fuse surface mounting fuse protector, it includes insulating ceramics substrate, coated in ceramic substrate upper surface
The quick fuse layer and the electrode positioned at ceramic substrate both ends in portion, the electrode are interconnected with quick fuse layer, described quick
The top of fuse layer is coated with thermal insulation layer, and heat insulation layer, the quick fuse layer both ends width and pottery are coated above the thermal insulation layer
Ceramic chip width is suitable, middle gradually inwardly to narrow and form the fuse part of one fixed width, overcurrent occurs in this way, working as
When, fuse layer can be with quick response, and rapid fusing, so as to protection equipment, and the fusing point of thermal insulation layer is molten less than ceramic substrate
Point, can effectively prevent ceramic substrate from the danger of explosion occurs, and the electrode is in two end faces of ceramic substrate and upper following table
The ag material that the both ends in face are respectively coated, be so advantageous to the conductive and heat-conductive of electrode, be advantageous to the quick fuse of fuse.
Brief description of the drawings
Fig. 1 is main structure diagram of the present utility model；
Fig. 2 is overlooking the structure diagram of the present utility model；
In figure：1. ceramic substrate, 2. fuse part, 3. quick fuse layers, 4. electrodes, 5. thermal insulation layers, 6. heat insulation layers.
Embodiment
In order that those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with the accompanying drawings
The utility model is described in further detail with most preferred embodiment.
As illustrated, a kind of quick fuse surface mounting fuse protector, it includes insulating ceramics substrate 1, coated in ceramic base
The quick fuse layer 3 of piece upper surface middle part and the electrode 4 positioned at ceramic substrate both ends, the electrode mutually interconnect with quick fuse layer
Logical, the top of the quick fuse layer is coated with thermal insulation layer 5, and heat insulation layer 6, the quick fuse layer are coated above the thermal insulation layer
Both ends width is suitable with ceramic substrate width, and centre gradually inwardly narrows to form fuse part 2.
Optimization, the fusing point of the thermal insulation layer is less than the fusing point of ceramic substrate.
Further, the electrode is the silver-colored material being respectively coated at the both ends of two end faces of ceramic substrate and upper and lower surface
Material.
In use, need to only snap onto fuse in pedestal, the electrode at both ends is connected with contact.
Due to a kind of quick fuse surface mounting fuse protector, it includes insulating ceramics substrate, coated in ceramic substrate upper table
The quick fuse layer and the electrode positioned at ceramic substrate both ends of Middle face, the electrode is interconnected with quick fuse layer, described
The top of quick fuse layer is coated with thermal insulation layer, and heat insulation layer, the quick fuse layer both ends width are coated above the thermal insulation layer
Suitable with ceramic substrate width, centre gradually inwardly narrows to form fuse part, in this way, when there is overcurrent, fuse layer
Can be with quick response, rapid fusing, so as to protection equipment, and the fusing point of thermal insulation layer is less than the fusing point of ceramic substrate, Ke Yiyou
Effect prevents ceramic substrate from the danger of explosion occurs, and the electrode is at two end faces of ceramic substrate and the both ends of upper and lower surface point
The ag material not coated, be so advantageous to the conductive and heat-conductive of electrode, be advantageous to the quick fuse of fuse.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
