Technical field
The present invention relates to rectifying tube technical fields, and in particular to a kind of explosion-proof rectifying tube and its method for packing.
Background technology
For the high current rectifier diode of large-scale convertor equipment, after backward voltage blocking failure occurs, can fuse
Device generates a very big reverse surge current before disconnecting.This reverse surge current can cause shell to burst or damage, so as to lead
There is security incident in cause personnel or equipment.
The prior art is useful for the inside explosion-proof technology of power device.The technology mainly has in element shell indoor design
One explosion-proof energy-absorbing buffering structure for absorbing the impact force that buffering falls explosion time one step ahead, avoids directly acting on ceramic ring, so as to
Ceramic ring is protected, ceramic ring is avoided to burst.But existing common energy-absorbing buffering structure is only to be made using one layer of elastic material
Explosion-proof coil structures or anti-explosion air-sac formula structure, explode strength it is bigger when, corresponding explosive forces cannot be inhaled completely
It receives, remaining impact force is directly delivered in shell ceramic ring, and ceramic ring is caused to burst.
Therefore, be adapt to the larger application scenario of such explosive force, it is necessary to the cooperation encapsulating package of design specialized it is explosion-proof
Rectifying tube.
The content of the invention
The technical problem to be solved by the invention is to provide a kind of better explosion-proof rectifying tubes of explosion-proof effect.

According to common knowledge, the first connection metalwork is connected metalwork with second and should ensure that certain flatness, roughness
And intensity, it is good with the contact of pipe lid and chip assembly after encapsulating to ensure.So as to not interfere with the performance of electrical aspect.Separately
Outside, for the structure of this explosion-proof buffering component when exploding generation, the first connection metalwork and the second connection metalwork limit sun
The deformation of pole molybdenum sheet and cathode molybdenum sheet simultaneously absorbs part explosion cushion effect.Moreover, the first connection metalwork and the second connection
Metalwork plays the role of connecting seat, for fixing the first explosion-proof buffering ring and the second explosion-proof buffering ring.First explosion-proof buffering ring
It is deformed with the second explosion-proof buffering ring under the action of explosive forces, so as to buffer and absorb explosive forces.
In a preferred embodiment, the explosion-proof buffering component includes the cathode molybdenum sheet for being located at pipe lid and chip assembly
Between the first connecting copper block, be located between pedestal and the anode molybdenum sheet of chip assembly the second connecting copper block, be connected with first
First polytetrafluoroethylene ring of copper sheet connection and the second polytetrafluoroethylene ring being connected with the second connecting copper block.Polytetrafluoroethylene (PTFE)
The explosion-proof buffering ring of making, intensity is high, processing performance and good insulation preformance, and can high temperature resistant.First connection metalwork and second
It is the copper billet being made using oxygen-free copper to connect metalwork, and ensures flatness, roughness and the concentricity of processing, from
And ensure to ensure that electric property is good with each contact surface energy good contact after encapsulating.
In one embodiment, the diameter of the first connection metalwork is straight not less than the cathode molybdenum sheet of chip assembly
Footpath, the diameter of the second connection metalwork are not less than the diameter of the anode molybdenum sheet of chip assembly.The explosion-proof rectifying tube is in integrally

7. explosion-proof rectifying tube according to claim 1, which is characterized in that between the second explosion-proof buffering ring and ceramic ring
Gap is not less than 2.5mm.
8. a kind of method for packing of explosion-proof rectifying tube, which is characterized in that using according to any one of claims 1 to 7 explosion-proof
Rectifying tube, the explosion-proof buffering component of the explosion-proof rectifying tube include the first connection metalwork, the first explosion-proof buffering ring, the second connection
Metalwork and the second explosion-proof buffering ring comprise the following steps in encapsulation：First the second explosion-proof buffering ring seal is attached on pedestal,
Then the second connection of encapsulation metalwork, then chip assembly is encapsulated, subsequently assemble the first connection metalwork and the first explosion-proof buffering
Ring is encapsulated by the component after the first connection metalwork and the assembling of the first explosion-proof buffering ring, package tube lid.
9. method for packing according to claim 8, which is characterized in that explosion-proof slow in the first connection metalwork of assembling and first
When rushing ring, first the first explosion-proof buffering ring is heated and softened, the oblique angle for then connecting metalwork according to first, which is caught in first, to be prevented
Quick-fried buffering ring completes assembling.
