By using above-mentioned technical proposal, connection sheet is arranged to construction section and linkage section two-stage structure so that even
Buffering effect can be played by connecing two sections of section and construction section so that connection sheet can be when length dimension limits in a certain range
Buffering effect is more preferably.
The present invention is further arranged to：The construction section extending direction and fusion tube axis parallel.
By using above-mentioned technical proposal, extending direction and fusion tube axis parallel that construction section is arranged make fuse pacify
It is easier to install with horizontality on pipe fitting.
The present invention is further arranged to：The inner ring and liner of sealing effect have been equipped between the end cap and fusion tube.
By using above-mentioned technical proposal, inner ring and liner are set to seal the gap between end cap and fusion tube so that no
Water is had to enter in fusion tube.
The present invention is further arranged to：The inner ring includes circumferential segment and the cladding fusion tube end face for coating one circle of fusion tube circumference
Planar section, be provided with through-hole in the middle part of the planar section.
By using above-mentioned technical proposal, the outside that setting inner ring is enclosed in fusion tube in the form of coating forms a circle cladding
The sealing station of formula, therefore sealing effect is more preferable, being provided with through-hole in the middle part of planar section allows melt to pass through through-hole and end cap phase
Even.
The present invention is further arranged to：The liner abuts with inner ring and end cap close respectively in circular ring shape and both ends of the surface
Envelope.
By using above-mentioned technical proposal, setting liner allows middle part and end cap of the melt by liner in circular ring shape
It is connected.
The present invention is further arranged to：The melt is equipped with sealing with end cap junction.
By using above-mentioned technical proposal, sealing is set to connect melt and end cap so that do not allow between melt and end cap
Easy accidental separation.
The present invention is further arranged to：Port position of the sealing in fusion tube forms complete covering surface, the envelope
It is tightly connected between glue and inner ring, liner.
It by using above-mentioned technical proposal, is tightly connected between sealing and inner ring, liner so that inner ring can be tightly attached to
The surface of fusion tube, and the surface that can be tightly attached to inner ring is padded, play better seal effect.
The present invention is further arranged to：The melt is made of silver plate and surface is provided with multiple punchings and forms fusing side by side
Place, the punching is rectangle so that spacing is equal between adjacent punching.
By using above-mentioned technical proposal, since punching is rectangular, fusing length when fusing is longer, is not easy
Occur overlapping but also causing the state of access after fusing not only.
In conclusion beneficial effects of the present invention are：
1, cushioning effect is played by directly installing flexible connection sheet in end cap, is bearing for a long time and is absorbing automobile
When travelling the impact collision external force for vibrations of jolting, its damage is avoided by connection sheet buffering；
2, when using the connection sheet of identical coefficient of elasticity, more long then its buffer capacity of length of connection sheet is stronger, by connection sheet
Be arranged the position of end cap edge make connection sheet extend outwardly it is longer apart from when fuse overall dimensions will not be long.

Specific implementation mode
Below in conjunction with attached drawing, invention is further described in detail.
As depicted in figs. 1 and 2, a kind of fuse suitable for new-energy automobile, including fusion tube 1 and in fusion tube 1
Melt 2, fusion tube 1 is interior to carry out anti-stopping leak arc filled with quartz sand filler 3.In order to enhance antiknock, anti-crack ability, fusion tube 1 is using oxidation
Aluminium porcelain is made.
As shown in Figures 2 and 3, two end caps 4 of fusion tube 1 have an end cap 4 made of copper, end cap 4 coat fusion tube 1 both ends of the surface and
Circumferential one by close end encloses.Inner ring 5 and liner 6 are lined between end cap 4 and fusion tube 1, inner ring 5 includes cladding 1 circumference one of fusion tube
The planar section 8 of 1 end face of the circumferential segment 7 of circle and cladding fusion tube, the middle part of planar section 8 are provided with through-hole 9, and liner 6 is in circular ring shape, and two
End face abuts sealing with inner ring 5 and end cap 4 respectively.The both ends of melt 2 pass through inner ring 5 and liner 6 end cap 4 with both ends later
Electrical connection.
As shown in figure 3, the cooperation by inner ring 5 and liner 6 to be fitted close between end cap 4 and fusion tube 1, end cap is avoided
4 abjections.In melt 2 sealing is connect by sealing 10 at 4 cooperation of end cap simultaneously so that be not easy between melt 2 and end cap 4 point
From, and port position of the sealing 10 in fusion tube 1 forms complete covering surface and seals its port and prevent quartz sand from leaking.Sealing 10
It is tightly connected between inner ring 5, liner 6 so that inner ring 5 can be tightly attached to the surface of fusion tube 1, and padding 6 can be tightly attached to
Better seal effect is played on the surface of inner ring 5.
As shown in figure 4, melt 2 is made of silver plate and surface is provided with multiple punchings 11 and is formed 12 at fusing side by side, punching 11
It is rectangle and so that there are wide spacing between adjacent punching 11.Due to punching 11 be it is rectangular, fusing when
The length that fuses is longer, is less prone to the state for overlapping but also causing access after fusing not only.
As shown in Figure 1, the downside of the marginal position of two end caps 4 is integrally formed with flexible connection sheet 13.Even
Contact pin 13 include with 1 axis parallel of fusion tube and to far from 13 direction of another connection sheet extend construction section 14 and connect construction section
14 and end cap 4 linkage section 15, be provided with mounting hole 16 on construction section 14.
Specifically used state：The connection sheet 13 at fuse both ends is mounted in the corresponding mounting base of new-energy automobile, two
Root connecting pole, which is each passed through after two mounting holes 16 to tighten by bolt cooperation, is fixedly connected with piece 13.It bears and absorbs for a long time
Running car jolts the impacts of vibrations when colliding external force, and construction section 14 and the linkage section 15 of connection sheet 13 play similar with shrapnel
Cushioning effect.
Assigned direction in this specific embodiment is intended merely to facilitate between each component of statement position relationship and mutually
The relationship of cooperation.This specific embodiment is only explanation of the invention, is not limitation of the present invention, art technology
Personnel can as needed make the present embodiment the modification of not creative contribution after reading this specification, but as long as
It is all protected by Patent Law in scope of the presently claimed invention.
