Description
Technical field
The utility model relates to technical field of new energy, and in particular to a kind of new-energy automobile fuse.
Background technique
" a kind of new-energy automobile fuse " technical solution applied before our company are as follows:
A kind of new-energy automobile fuse, including ceramic tube, the ceramic tube are 95 alumina ceramic tubes, the ceramics
Be fixedly connected with sliver strip melt inside pipe, external both ends be arranged in emit terminal, it is described in emit terminal outer be arranged it is outer emit connecting terminal,
Terminal is emitted in described and emits connecting terminal outside and is symmetrically pressed, and outer emit is provided with through-hole on connecting terminal, in the ceramic tube
Quartz sand is filled in portion, and the quartz sand carries out the filling of ceramic tube by through-hole.
But above-mentioned fuse is two strip holes and plug hole (such as Fig. 1), alumina ceramic tube due to what is opened in interior emit
It emits in assembly inside, process is tedious, and main cause has two aspects:
It on the one hand is to need upper and lower two strip holes and plug hole keeping concentricity (concentricity) when emitting in press-fitting.
Therefore, it emits in assembly inside, first any pressure on one side, then needs a tooling directly to come from this end plug sub-aperture through the other end real
It now positions, working efficiency is low, is unfavorable for operating, and brings to personnel's operation many cumbersome.
On the other hand, two strip holes are inside emitted apart from narrow, are unfavorable for wearing melt, are restricted volume production and efficiency.
Utility model content
The purpose of this utility model is to solve the above problems, and it is relatively easy to provide a kind of processing technology thereof, saves process
And cost, and more efficient new-energy automobile fuse.
To achieve the above object, the utility model provides the following technical solutions:
A kind of new-energy automobile fuse, including ceramic tube and its internal sliver strip melt being fixedly connected, external both ends
Emit terminal in being arranged, it is described in emit terminal outer be arranged it is outer emit connecting terminal, it is described in emit terminal inner to be provided with fillet rectangular
Body through-hole, it is described in emit terminal and emit connecting terminal outside and symmetrically press, the sliver strip melt is for being truncated overload and short circuit electricity
Stream, outer emit are provided with through-hole on connecting terminal, the ceramic tube inside fills quartz sand, and the quartz sand is carried out by through-hole
The filling of ceramic tube.
Further, the length-width ratio of the rounded cuboid through-hole is 26:16.
Further, the ceramic tube is 95 alumina ceramic tubes.
Preferably, the ceramic tube and sliver strip melt are welding.
Preferably, the through-hole diameter is 5.4mm.
Further, the utility model is suitable for 1000 volts of electric cars below, charging pile and is suitable for antidetonation, resistance to height
Temperature, the demanding occasion of the class of insulation
The utility model has the beneficial effects that:
The utility model effectively improves relative to existing fuse, interior cap mechanical strength, and processing technology is relatively former
Carry out two strip holes and one fills the simple of sand hole, has saved process and reduced moulds of industrial equipment cost and processing cost；Simultaneously
Fuse assembly technology is simpler than currently existing scheme, improves whole working efficiency.Overall mechanical strength is high, it is firm can
It leans on, is highly-safe.
