Fig. 1 is the partial sectional view of the resistor component 1000 of the integrated fuse illustrated according to one embodiment of the invention.
With reference to this figure, the resistor component 1000 of integrated fuse comprises: resistor 100, fuse 200, linkage unit 300 and shaping (molding) unit 400.
Resistor 100 is function for playing resistance and limits the element of impulse current.Resistor 100 can be electric wire 150 is rolled onto the form on ohmic load 110 (with reference to Fig. 2).Can extend from the cap (cap) 130 of the end being formed at resistor 100 and have the 1st lead-in wire 101.
Fuse 200 is the elements making loop connect short circuit according to overcurrent or heat.From the fuse cap 230 of an end being formed at fuse 200, can extend that having goes between with the 1st 101 the corresponding 2nd goes between 201.
Linkage unit 300 is structures that resistor 100 and fuse 200 are inserted respectively.Accordingly, resistor 100 and fuse 200 connect by linkage unit 300 is one.Now, linkage unit 300 is between resistor 100 and fuse 200, into a line with their shapes.
Forming unit 400 is the formations surrounding resistor 100 and fuse 200, linkage unit 300.Forming unit 400 makes resistor 100, fuse 200 and linkage unit 300 form as one, that is, become one (piece).
According to this structure, the connection between resistor 100 and fuse 200 becomes firmer.
Further, resistor 100 and fuse 200 are interconnected and become one.
Secondly, the concrete structure of above-mentioned resistor 1000 is described with reference to Fig. 2.
Fig. 2 be for illustration of illustrative in Fig. 1, according to the profile of the internal structure of the resistor component 1000 of the integrated fuse of one embodiment of the invention.
With reference to this figure, first, resistor 100 can possess: the 1st lead-in wire 101, ohmic load 110, resistance cap 130, electric wire 150 and protection portion 170.
1st lead-in wire 101 extends from resistance cap 130.1st lead-in wire 101 is connected to circuit board.
Ohmic load 110 has drum substantially.Ohmic load 110 can be formed by ceramic material.
Resistance cap 130 is attached to an end of ohmic load 110.Resistance cap 130 has the diameter being greater than ohmic load 110, is formed by metal material.
Electric wire 150 can bear high current and can not fuse (fusing).Such as, electric wire 150 can be formed by the alloy of copper (Cu) with nickel (Ni).Electric wire 150 is wound into ohmic load 110 with spiral.One end of electric wire 150 is connected to resistance cap 130, and the other end is connected to linkage unit 300.
Protection portion 170 is coated with and installs to ohmic load 110 to surround electric wire 150.Protection portion 170 can be formed by silicon material, can be formed particularly by aqueous silicon.Accordingly, protection portion 170 can, when electric wire 150 fractures because of overcurrent, prevent its fragment from scattering.
Secondly, fuse 200 can have the 2nd lead-in wire 201, fuse load 210, fuse cap 230, short 250 and trigger unit 270.
2nd lead-in wire 201 prolongations from fuse cap 230.Corresponding 1st lead-in wire 101 of 2nd lead-in wire 201.Go between 101 identical with the 1st, the 2nd lead-in wire 201 can be form zinc-plated on copper cash.If described tin is less than 30 % by weight, then weldability is not outstanding; If more than 40 % by weight, then conductivity is not outstanding.
Fuse load 210 is cylinder type, is to extend to be formed.Fuse load 210 can be formed by salic ceramic material.Now, described pottery can containing the aluminium oxide of 55 % by weight to 85 % by weight.
If aluminium oxide is less than 55 % by weight, then the content of other compositions outside alumina increases, thus causes economy sharply to decline.Further, if aluminium oxide is more than 80 % by weight, then conductivity can sharply decline.Inventor thinks that the content of this aluminium oxide is preferably 55 % by weight to 70 % by weight.
Fuse cap 230 is arranged to an end of the length direction along fuse load 210.Further, fuse cap 230 is formed by conductive material.
Specifically, fuse cap 230 can comprise: the plate of copper material; And Gold plated Layer, relative to the described plate of 100 % by weight, the tin of 30 % by weight to 40 % by weight is plated on the surface of described plate and is formed.At this, the advantage of copper is good economical benefit and resistive is low.Further, tin makes the weldability between the 2nd lead-in wire 201 and fuse cap 230 good.
Short 250 is the parts connecting fuse cap 230 and linkage unit 300.Specifically, short 250 can comprise the tin layers being coated with and being contained in the outer peripheral face of fuse load 210.
Described tin layers specifically can by following Structure composing: nitric acid silverskin 251, at the outer peripheral face of the fuse load 210 with salt acid elution, gold-plated with silver nitrate; And tin film 253, nitric acid silverskin 251 plates ashbury metal.
Described tin layers, on the outer peripheral face of fuse load 210, can be formed with 2 μm to 10 μm thickness.If the thickness of described tin layers is less than 2 μm, then time gold-plated, difficulty is large, cannot realize the short circuit of short 250 smoothly.Further, if the thickness of described tin layers is more than 10 μm, then the short circuit of short 250 can too soon (too responsive).
Trigger unit 270 is arranged to surround short 250 to promote the short circuit of short 250.Specifically, trigger unit 270 can be the epoxy resin film arranged along the circumferential direction of fuse load 210, and described epoxy resin mould is film that the heat applied according to short 250 promotes the intensification of short 250, that formed by epoxy resin.
Linkage unit 300 is the formations for making ohmic load 110 and fuse load 210 insert respectively.And be the part be connected with electric wire 150 and the respective one end of short 250.Linkage unit 300 is formed as electrical resistance conductor.The concrete structure of linkage unit 300 is described with reference to Fig. 3.
Again with reference to Fig. 2, forming unit 400 is the structures surrounding ohmic load 110, fuse 200 and linkage unit 300 and form the outward appearance of resistor 1000.Accordingly, resistor 1000 can be single-piece (piece) structure.
Forming unit 400 can be formed by silicon material.Now, the hardness of the silicon of forming unit 400 can be greater than the silicon of protection portion 170.Accordingly, forming unit 400 more firmly can protect whole resistor 1000.
According to this formation, according to heat more than the setting benchmark applied to fuse 200, short 250 can be fused.Now, because possessing described tin layers, short 250 can fuse being shorter than in the short time in the past.
Specifically, the fusing point of the nickel be in the past suitable for is 1455 DEG C, and the fusing point of copper is 1084.5 DEG C, but the fusing point of the tin of tin film 253 is 231.93 DEG C, and the nitric acid silver point of nitric acid silverskin 251 is 212 DEG C.In other words, the fusing point of short 250 is only 1/5 ~ 1/7 of material in the past, and therefore short 250 can more promptly fuse.
Tin as the main component of described tin layers is difficult to directly gold-plated to fuse load 210.In order to head it off, adopt in the present embodiment with the following method: first, the outer peripheral face of the fuse load 210 with salt acid elution is formed by the gold-plated nitric acid silverskin 251 of silver nitrate, secondly, nitric acid silverskin 251 is formed by the gold-plated tin film 253 of ashbury metal.According to this formation, short 250 can be made a response to the heat more than benchmark applied by resistor 100, thus is promptly shorted.
Further, the fusing of short 250 because of trigger unit 270 being accelerated.To this, with reference to the experimental result of the table 1 of the fuse 200 to the described epoxy resin film of employing, illustrate trigger unit 270.
[table 1]
Known with reference to above experimental result, be suitable for the result of described epoxy resin film as trigger unit 270, on average achieve the short circuit of fuse 200 with 39.74 seconds.But, when not being suitable for described epoxy resin film, on average achieved the short circuit of resistance type fuse with 49.04 seconds.
Therefore, as trigger unit 270, described epoxy resin film can shorten the duration of short circuit of average about 9.7 seconds.This roughly shortens the duration of short circuit of about 20%.
With reference to Fig. 3, the formation relevant to above-mentioned linkage unit 300 is described.
Fig. 3 is the profile of the pith that the part relevant to the linkage unit 300 of Fig. 2 is shown.
With reference to this figure, linkage unit 300 is the electric conductors formed by monolithic.
Specifically, linkage unit 300 can be the holder possessing the 1st holddown groove 310 and the 2nd holddown groove 330.At this, the 1st holddown groove 310 and the 2nd holddown groove 330 can be arranged to open in the opposite direction.
Described holder also can have the next door 350 separating the 1st holddown groove 310 and the 2nd holddown groove 330.
According to above-mentioned formation, ohmic load 110 can be inserted into the 1st holddown groove 310, and fuse load 210 can be inserted into the 2nd holddown groove 330.Accordingly, the connection between ohmic load 110 and fuse load 210 easily realizes by described holder.
Further, because possessing next door 350, when ohmic load 110 and fuse load 210 are inserted into the 1st holddown groove 310 and the 2nd holddown groove 330 respectively, the degree of depth immobilization of insertion can be made.
