Abstract
The invention relates to a high-surge-resistant fuse wire which is used for suppressing metal ion gas caused by a heat source generated by high current flowing through an electronic circuit. The high-surge-resistant fuse wire comprises a columnar hollow body, a pair of electrodes which cover the upper and lower end surfaces of the columnar hollow body, a fuse wire which is arranged in the internal part of the columnar hollow body, and tin which fills between the electrodes and the fuse wire. An arc blocking agent fills in the opening of one side of the columnar hollow body. The beneficial effects of the high-surge-resistant fuse wire are that metal ion gas caused by the heat source generated by high current flowing through the electronic circuit can be suppressed so that the fuse wire is enabled to bear higher current and thus the hollow body of the covered fuse wire is enabled not to be ruptured.
Description
Technical field
The present invention has about the resistance to high surging fuse of one, especially a kind of the big current because flowing through electronic circuit can be suppressed to produce thermal source and the resistance to high surging fuse of the metal ion gas caused.
Background technology
Fuse, also known as fuse, fuse, one is connected to the disposable assembly in order to protective circuit on electronic circuit; when circuit power on flow through large time; make metal wire wherein or sheet metal produce high temperature and fuse, cause opening a way and interruptive current, avoid coming to harm with protective circuit.The fuse manually more renewed is needed to resume operation to make circuit after old blown fuse.
Produce high temperature because being subject to electronic circuit big current causes existing fuse structure not come to harm to protect electronic circuit in the past; therefore must be fused; but then manually need be replaced with new fuse after fusing could allow electronic installation continue normal operation, and therefore money and human cost all can improve.Again, existing fuse, because heat insulation structural designing technique is not good enough, causes fuse usually because of the temperatures involved be created in electronic circuit and the situation that fuses usually occurs.
Moreover, general existing fuse causes fuse to fuse because of the high temperature that overcurrent is inducted, and while fusing, make hollow cylindrical body inside produce the metal ion gas of described fuse, this metal ion easily makes described hollow cylindrical body inside produce electric arc, and the generation of electric arc easily makes described hollow cylindrical body break.
Edge this, the present inventor is because the problem of existing fuse structure lacks and structural design does not attain the desirable fact, namely inventor sets about researching and developing its scheme solved, wish to develop a kind of resistance to high surging fuse having more fail safe, convenience and economic benefit, to promote the development of this industry, satisfy the design when many and have generation of the present invention.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of resistance to high surging fuse, make to suppress the thermal source because the big current flowing through electronic circuit produces and the metal ion gas that causes.
Technical scheme of the present invention is as follows:
A kind of resistance to high surging fuse, comprise on a column type hollow body, a pair covering described column type hollow body, fuse and that the electrode, of lower surface is arranged at described column type hollow body inside fills out the tin be overlying between described electrode and fuse, the opening part being overlying on described column type hollow body side filled out by an electric arc blocking agent.
Above-mentioned resistance to high surging fuse, described electrode is a concavity cup electrode.
Above-mentioned resistance to high surging fuse, described fuse is made up of a single metal material.
Above-mentioned resistance to high surging fuse, described electric arc blocking agent is a high molecular electric arc blocking agent.
Above-mentioned resistance to high surging fuse, fill out that the amount of covering is less than described column type hollow body internal volume 1/2nd of described electric arc blocking agent.
Above-mentioned resistance to high surging fuse, also includes shrinkage cast film, its after being heated completely evenly coating described column type hollow body and electrode to protect fuse.
Above-mentioned resistance to high surging fuse, also includes shrinkage cast film, and it is only evenly coated to described column type hollow body to protect fuse after being heated.
Above-mentioned resistance to high surging fuse, the internal diameter of described shrinkage cast film is greater than the external diameter of described column type hollow body.
Above-mentioned resistance to high surging fuse, described column type hollow body is one of them of a hollow cylindrical body or cube rod hollow body.
Beneficial effect of the present invention for: suppressing the thermal source that the big current because flowing through electronic circuit produces and the metal ion gas caused, making fuse bear more big current and do not cause the hollow body of coating fuse to break.
