Abstract
The invention discloses the microminiature paster fuse of electronic applications; including the insulated substrate, fuse piece and two electrodes being made up of laminated structure; the insulated substrate for magnesia and alundum (Al2O3) by forming; two electrode is respectively arranged on the both sides of fuse piece and connected as one with fuse piece; the middle part of the fuse piece is provided with the perforate that some rows are arranged in the form of vertical, and the surface of the fuse piece and electrode is covered with insulating protective layer.Compared with prior art, in fuse piece central aperture so that this paster fuse manufacture craft is simple, and low manufacture cost, operating chacteristics is more easy to control, product safety and reliability, makes product operating chacteristics consistent, I2T values uniformity is high, and breaking capacity improves, power consumption relative reduction, so as to the accurate protection circuit of safety and the critical elements of circuit.
Description
Technical field
The present invention relates to electronic applications, more particularly to a kind of microminiature paster fuse.
Background technology
Fuse be it is a kind of be connected on electronic circuit to the disposable elements of protection circuit, when electric current is excessive on circuit
When, metal wire or sheet metal therein is produced high temperature and is fused, cause open circuit and interruptive current, with protect a circuit from by
Injury.Existing paster fuse causes operating chacteristics inconsistent, I because of fuse piece structure design2T values are inconsistent, breaking capacity
Difference, so as to the Important Components being unable in safety protective circuit and circuit.Also, existing paster fuse power consumption is larger, using
Battery capacity can be lost in new energy resources system.Thus, prior art needs to improve.
The content of the invention
Present invention aim to address disadvantages described above, there is provided a kind of microminiature paster fuse, its is simple in construction, volume
Small, current range is big, I2T values uniformity is high, and breaking capacity improves, and operating chacteristics is more easy to control, product safety and reliability, with gram
The defects of taking in the prior art.
The purpose of the present invention is achieved in the following ways：
Microminiature paster fuse, including insulated substrate, fuse piece and two electrodes being made up of laminated structure, the insulated substrate by
Formed for magnesia and alundum (Al2O3), the fuse piece is close to the one side of insulated substrate, and two electrode is respectively arranged on fuse piece
Both sides and connected as one with fuse piece, the width of the fuse piece is less than the width of electrode, and the middle part of the fuse piece is provided with some
The perforate arranged in the form of vertical is arranged, the surface of the fuse piece and electrode is covered with insulating protective layer.
What deserves to be explained is when rated current passes through paster fuse, fuse is in thermal equilibrium state, and the paster is protected
Dangerous silk fuse piece tapping does not change, product safety work.When circuit operation irregularity or it is short-circuit when, pass through paster fuse
Electric current is much larger than rated current, and the thermal balance of paster fuse fuse piece is broken, fuse piece weak spot --- and the temperature of-tapping is rapid
Lifted and fused, reach safety protective circuit purpose.
In described above, the scheme that is more highly preferred to, the perforate is provided with three rows altogether.
In described above, the scheme that is more highly preferred to, the fuse piece is made using ag material.
In described above, the scheme that is more highly preferred to, the insulating protective layer is made up of glass material.
The invention has the advantages that：The present invention's is reasonable in design, and small volume, current range is big, with showing
There is technology to compare, in fuse piece central aperture so that this paster fuse manufacture craft is simple, low manufacture cost, and operating chacteristics is more
It is easy to control, product safety and reliability, make product operating chacteristics consistent, I2T values uniformity is high, and breaking capacity improves, and power consumption is relative
Reduce, so as to the accurate protection circuit of safety and the critical elements of circuit.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention.
In figure, 1 is fuse piece, and 2 be electrode, and 3 be perforate.
Embodiment
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings.
The present embodiment, reference picture 1, the microminiature paster fuse in this programme, it is mainly used in DC circuit protection, welding
It was used for flow short-circuit safeguard protection on PCB, it implements insulated substrate, the fuse piece 1 and two that structure includes being made up of laminated structure
Electrode 2, for the insulated substrate by being formed for magnesia and alundum (Al2O3), the fuse piece 1 is close to the one side of insulated substrate, institute
State two electrodes 2 to be respectively arranged on the both sides of fuse piece 1 and connect as one with fuse piece 1, the width of the fuse piece 1 is less than the width of electrode 2
Degree, makes product operating chacteristics more easy to control, so as to improve breaking capacity and I2T values, and make power consumption relative reduction.The fuse piece 1
Middle part be provided with the perforate 3 that is arranged in the form of vertical of three rows, the surface of the fuse piece 1 and electrode 2 is covered with insulating protective layer.
In addition, the fuse piece 1 is made using ag material.The insulating protective layer is made up of glass material.With it is existing
Technology is compared, in the central aperture 3 of fuse piece 1 so that this paster fuse manufacture craft is simple, low manufacture cost, and operating chacteristics is more
It is easy to control, product safety and reliability, make product operating chacteristics consistent, I2T values uniformity is high, and breaking capacity improves, and power consumption is relative
Reduce, so as to the accurate protection circuit of safety and the critical elements of circuit.
Above content is to combine specific preferred embodiment further description made for the present invention, it is impossible to assert this
The specific implementation of invention is confined to these explanations.For general technical staff of the technical field of the invention, not
On the premise of departing from present inventive concept, some simple deduction or replace can also be made, are regarded as protection scope of the present invention.
