Description
Technical field
The utility model is related to electrical protection component fields, are provided in particular in a kind of multiple-level surface attachment fuse.
Background technology
With the development of modern electronic technology, portable modern electronic equipment is from mobile phone, laptop to tablet computer
Deng into huge numbers of families, these electronic equipments are required for lithium ion battery power supply, charger be realize energy convert-to lithium ion
The indispensable weapon of battery charging.Recent battery explosion, charging overheat, charger are smoldered and on fire or even fire etc. causes great peace
Full accident occurs often, higher and higher to the safe design code requirement of battery and charger.Fuse is as second class protection member
How device plays safe and reliable protective effect in electronic circuit, closely related with the characteristic of fuse.Immobilising device
The fuse of type fuse and hollow type is two big main Types of small-sized multiple-level surface attachment fuse at present.
Hollow type surface mounting fuse protector also includes two major class：Made using ceramic tube as the fuse of housing and with organic matter
Fuse for housing.Fuse both ends are welded on two ends by the fuse using ceramic tube as housing by scolding tin,
Scolding tin meeting and fuse materials during melting（Such as copper）Low-melting alloy is formed, the problem of easily disconnection under high-temperature soldering, especially
It is the popularization of electronic product pb-free solder, this phenomenon becomes increasingly conspicuous；And the copper cap of end is directly set on ceramic tube, can not be done
To being fully sealed, product is vulnerable to ambient atmos（Such as vapor, acid vapor）Influence, and then influence life of product.To have
Machine object is placed on as the fuse fuse of housing among cavity, as product has Japanese Patent to announce JP2006-244948 in
Two product disclosed in state patent 201110123326.X is all to make hanging fuse with circuit board overlapping（Conducting wire）It pastes on type surface
Fuse is filled, fuse and surface electrode are linked together with the mode of plating, solve the ceramic tube failure welding of square
Problem.But this design also has notable defect：First, fuse is located among product, by the way that the electrode come connection surface is electroplated, but
The coefficient of expansion of the through-hole inner hole wall base material of circuit board material is larger, all higher than the coefficient of expansion of coated metal, in this way higher
Under temperature condition, coated metal can be removed with base material, be elongated or even be pulled off so as to cause fuse, can not produce relatively low specification
Product；Secondly, it in fuse exposure through-hole, fixes and then easily by injured, the connectivity of fuse and fuse is caused to be deteriorated, from
And influence properties of product.
Immobilising device type fuse includes two major class of individual layer fuse-type and multilayer fuse-type.Individual layer fuse-type is using ceramics
Etc. organic shells such as inorganic housing or FR4, one layer of metal is plated on its surface, is then etched into circuit, then stamp layer protecting film.
With the raising of disjunction condition, the protective film on fuse, which can be broken through, causes a large amount of high temperature substances to spray, therefore its breaking capacity
Will not be very high, security risk is existed simultaneously, effective safeguard protection can not be played the role of.Multilayer fuse uses similar lamination electricity
The technique of appearance alternately prints fuse and printing ceramic slurry on support plate, and by precuring, multilayer fuse is back and forth formed with this,
The sintering of product is completed finally by co-firing technology.Also have in the prior art and the cavity plate containing cavity is stacked in fuse surface
And then multilayer hollow fuse is made, such fuse is promoted compared with individual layer fuse, fusing ability.
In the prior art, for multilayer fuse, termination electrode usually is set in the above, the lower lid, before fuse
Side termination electrode is made in face and below electroplated metal layer, and realization termination electrode is electrically connected with melt.This set usually can be due to
Coating is removed with base material and fuse is caused to be cut off with being electrically connected for termination electrode, influences the job stability of fuse；It is meanwhile right
In multilayer hollow fuse, due to the setting of cavity, the structural strength of fuse in itself is weakened, and influences the disjunction energy of fuse
Power, there are security risks.
