Abstract
The utility model relates to a fuse with the filter effect, which comprises a safe electric conductor and at least two electrode terminals which are electrically connected with the end of the safe electric conductor. The surface of the safe electric conductor is covered with a layer of magnetic ceramic body; at least two conductive layers are arranged between the end of the safe electric conductor and electrode terminals; the end of the safe electric conductor, the conductive layer, and the electrode terminals are electrically connected with each other. One electrode terminal is a conducting wire body, and the other electrode terminal is a conducting cover body. The electrode terminals are respectively covered with the ends of the magnetic ceramic body. The fuse of the utility model has the advantages of few circuit elements and low cost and has the double functions protecting the circuit and filtering.
Description
The utility model relates to a kind of fuse, particularly relates to a kind of the utilization in what one electric system or the electronic circuit system, has the fuse with filter action of circuit protection and filter effect concurrently.
Be generally the processing safety of protection electric system or electronic circuit system; big city is provided with a fuse at each power unit of system, to avoid excessive because of system power, and produces heat energy; and then with the circuit burnout of this electric system or electronic circuit system, even cause fire.
Development trend along with miniaturization, thin typeization, lightweight and the multifunction of electronic product, main element in the electronic circuit system, as resistance, electric capacity, inductance etc., also improved relatively by the ratio of waferization, therefore, the packaging density of Circuits System is also just along with increasing, simultaneously, the flux that element that it is contiguous or electronic loop are also just relatively leaked is easily interfered, and cause electromagnetic interference (EMI), so the electromagnetic interference (EMI) of electronic product is eliminated the bare bones that has become the Circuits System design.Certainly, the fuse of necessary element also must cooperate this kind trend in the electronic system.
From the above, the electromagnetic interference that one burning voltage can be provided and avoid electronic product for each power supply unit that makes system, usually the fuse of system can be connected a filter element, to reach the effect of filtering and protective circuit, as shown in Figure 1, connection pin type fuse 11 in the past is connected with filter element 12, can reach the effect of filtering and protective circuit; Yet, in this manner, must use fuse and filter element simultaneously just by what, when this can increase the assembler, also there is the problem that element is many, cost is high.
Main purpose of the present utility model is to provide a kind of fuse that reduces circuit element, reduces cost and have concurrently protective circuit and filter function.For achieving the above object, the utility model is taked following measure:
Fuse with filter action of the present utility model, comprise an insurance electric conductor and with at least two electrode terminals being electrically connected respectively of end of insurance electric conductor, its feature is at what:
Insurance electric conductor surface is coated with one deck magnetic ceramics body.
Described fuse with filter action, its feature what:
Described electrode terminal is a conductive wire body.
Described fuse with filter action, its feature what:
Described electrode terminal is a conduction cover body, and electrode terminal covers the end of closing the described magnetic ceramics body of what respectively.
Described fuse with filter action, its feature what:
Described fuse also comprises at least two conductive layers that are arranged between described insurance electric conductor end and electrode terminal, and end, conductive layer and the electrode terminal of insurance electric conductor are electrically connected mutually.Be elaborated as follows by Cui embodiment and accompanying drawing to fuse of the present utility model:
Description of drawings:
Fig. 1 is the schematic perspective view of fuse and filter element in the past.
Fig. 2 is of the present utility model first schematic diagram than Cui embodiment.
Fig. 3 is of the present utility model second schematic perspective view than Cui embodiment.
Fig. 4 is the of the present utility model the 3rd schematic perspective view than Cui embodiment.
Fig. 5 is the of the present utility model the 3rd sectional schematic diagram than Cui embodiment.
As shown in Figure 2, of the present utility model first comprises than Cui embodiment: insurance electric conductor 21, a magnetic ceramics body 22 and one group of electrode terminal 23.
Insurance electric conductor 21 is electric conductors that can bear certain electric current (voltage) amount.
At this, what deserves to be mentioned is that the material of above-mentioned magnetic ceramics body 22 can be made of ambrose alloy zinc-iron oxygen magnet etc.
As shown in Figure 3, of the present utility model second comprises than Cui embodiment: insurance electric conductor 31, a magnetic ceramics body 32 and one group of electrode terminal 33.Insurance electric conductor 31 is electric conductors that can bear certain electric current (voltage) amount.Magnetic ceramics body 32 coats above-mentioned insurance electric conductor 31, utilizes the magnetic characteristic of magnetic ceramics body 32, can filter the noise in the above-mentioned insurance electric conductor 31, so that the fuse tool filter effect of present embodiment.Electrode terminal 33 is conduction cover bodies, and is electrically connected with above-mentioned insurance electric conductor 31 two ends respectively, and covers the both ends of closing the above-mentioned magnetic body 32 of what respectively.The material of above-mentioned magnetic ceramics body 32 can be ambrose alloy zinc-iron oxygen magnet etc.
As Fig. 4 and shown in Figure 5, the 3rd embodiment of the present utility model comprises: an insurance electric conductor 41, a magnetic ceramics body 42, one group of conductive layer 43 and one group of electrode terminal 44.Insurance electric conductor 41 is electric conductors that can bear certain electric current (voltage) amount.Magnetic ceramics body 42 coats above-mentioned insurance electric conductor 41, and the magnetic characteristic of magnetic ceramics body 42 can be filtered the noise in the above-mentioned insurance electric conductor 41, makes the fuse tool filter effect of present embodiment.Electrode terminal 44 is conduction cover bodies, and is electrically connected with above-mentioned insurance electric conductor 41 two ends by the conductive layer 43 of above-mentioned tool satisfactory electrical conductivity respectively, and cover both ends of closing the above-mentioned magnetic body 42 of what respectively.
The utlity model has following effect:
Can find out from the foregoing description, coated by magnetic ceramics body 22, magnetic ceramics body 32 and the magnetic ceramics body 42 of a tool filter effect respectively by what insurance electric conductor 21,31,41 of the present utility model, so fuse of the present utility model still has filter function except that the effect with fuse in the past.Say that simply fuse of the present utility model is single element, can finish the effect of protective circuit and filtering again simultaneously, this can reduce the use of filter element, and reach the effect that reduces cost a circuit.Moreover, have filter function by what fuse of the present utility model, thus the noise of power supply output can be filtered, and then reach the effect that burning voltage is provided.
