Fig. 2 is the power amplifier protection of pipe structural schematic diagram of the present invention；
Fig. 3 is flow chart of the method for the present invention；
In figure, 1- flange support plates, 2- ring flanges, 3- tube core pedestals, 4- shells, 5- grooves.
Specific implementation mode
Technical scheme of the present invention is described in further detail below in conjunction with the accompanying drawings, but protection scope of the present invention is not limited to
It is as described below.
It is fixed in screw to illustrate power tube by taking EGNC210MK power tubes as an example, ring flange deformation damage
After the reason of bad power tube, and the structures and methods of use the application, the concrete principle of ring flange deformation is avoided；
As shown in Figure 1, for the structural schematic diagram of EGNC210MK power tubes, which includes tube core pedestal 3, shell 4 and method
The bottom of blue disk 2, the tube core pedestal 3 is fixed on the upper surface of the ring flange 2, and be provided in tube core pedestal 3 opening to
On groove 5, the groove 5 for installing shell 4 described in power amplifier tube chip by resin bonding at the top of tube core pedestal 3, and
Groove 5 is sealed, threaded hole is provided on ring flange 2（Coordinate the screw of M2.5 × 6）；The upper surface of the ring flange 2 is also set
It is equipped with boss, the lower surface of tube core pedestal 3 is provided with pit, and the boss is matched with pit realizes ring flange 2 and wick-based
After the assembly of seat 3, by way of welding or resin bonding, ring flange 2 and tube core pedestal 3 are fixed together；
In power tube installation process, power tube is mounted in aluminium cavity using the stainless steel screws of M2.5 × 6；But pass through
It finds that more power amplifier tube failure is bad after subsequent thermocycling, is found when removing analysis to defective products, all defective products
Power tube shell 4 is all cracked, and buckling phenomenon occurs in the ring flange 2 of power tube；
To power tube using being caused ring flange 2 to be bent by temperature stress effect under high/low temperature again after screw installation, to make shell 4
Cracking, the reason of damaging power tube, are further analyzed discovery, and the ring flanges 2 of the EGNC210MK power tubes is using can cut down
The stacking of metal material three is added into, and overall thickness only has 1.78mm；It is acted on by temperature stress under high/low temperature, is added due to three stackings
The coefficient of thermal expansion that can be cut down between metal material ring flange 2 and aluminium cavity is different, and ring flange is again very thin, and only 1.78mm works as method
Blue disk will deform when can not meet with stresses, and discharge stress, and ring flange 2 is firmly fixed on aluminium cavity by screw at this time
On, thus power amplifier pipe flange it is complete after so that power amplifier shell 4 is cracked, power tube is damaged.
For such case, the present invention provides a kind of power amplifier protection of pipe structure preventing ring flange installation deformation, such as Fig. 2 institutes
Show, which includes flange support plate 1 and the power tube with ring flange 2, lower surface and the flange support plate 1 of the ring flange 2
Upper surface is welded and fixed, and forms the power tube of flanged support plate 1.
In embodiments herein, the thickness of the flange support plate 1 is 4mm；The flange support plate 1 and ring flange 2
Length and width dimensions are identical；The flange support plate 1 is the copper support plate that upper surface is provided with plating nickel gold Cu/Ep Ni5Au0.5.
As shown in figure 3, a kind of forming method of power amplifier protection of pipe structure for preventing ring flange installation from deforming, including
Following steps：
S1. it is 4mm to process thickness using copper coin, and length and width dimensions are equal to the copper support plate of the ring flange 2；
S2. in copper support plate plating nickel gold Cu/Ep Ni5Au0.5, flange support plate 1 is formed；
S3. the low temperature tin cream of one layer of 0.12~0.15mm thickness is brushed in the upper surface of the flange support plate 1（SnBiAg low temperature soldering paste）；
S4., the ring flange of power tube 2 is positioned over to the upper surface of flange support plate 1；
S5. by after ring flange 2 and 1 consistency from top to bottom of flange support plate, flange support plate 1 is positioned on warm table；
S6. the temperature of control warm table is in 170 DEG C, carries out heating welding to ring flange 2 and flange support plate 1, is formed flanged
The power tube of support plate 1；
S7. after the completion of heating welding, the power tube of flanged support plate 1 is taken out, after natural cooling, machine-shaping terminates.
In embodiments herein, due to being usually to use resin bonding between the shell 4 and tube core pedestal 3 of power tube
Together（Such as EGNC210MK power tubes）, it is more than after 200 DEG C in temperature, resin can soften, and there may be displacements for shell 4, and
Influence the leakproofness between shell 4 and pedestal 3.Therefore when being sintered power amplifier pipe flange with flange support plate, temperature is no more than 200
℃.Traditional PbSn soldering paste cannot be selected when being sintered thus（183 DEG C of fusing point, when welding general temperature to reach 220 DEG C could shapes
At good solder joint）, we choose SnBiAg alloy low temperature soldering paste, and the fusing point of the alloy low temperature soldering paste is 143 DEG C.When sintering we
The low temperature tin cream of one layer of 0.12~0.15mm thickness is first brushed on flange support plate, then power tube is placed on flange support plate 4, after alignment
It is placed on to heat on the warm table that temperature setting is 170 DEG C and be sintered；In embodiment, due to needing the work(of flanged support plate 1
Pipe is put on product cavity, therefore also needs to open up multiple threaded holes for flange support plate 1, is convenient to the work(of flanged support plate 1
Put the assembly between pipe and product cavity.Due to there is the flange support plate 1 of 4mm thickness under ring flange 2, it is entirely capable of resisting under high/low temperature
Stress, can effectively avoid flange distortion and cause power amplifier tube shell crack, damage power tube, to sum up, the present invention can be effective
It prevents the ring flange of power tube from deformation being installed, and then effectively prevents power tube damage, brought to installing and using for power tube
Convenience.
Finally, it should be noted that the above is only a preferred embodiment of the present invention, it should be understood that the present invention is not office
Be limited to form disclosed herein, be not to be taken as excluding other embodiments, and can be used for various other combinations, modification and
Environment, and can be in contemplated scope described herein, modifications can be made through the above teachings or related fields of technology or knowledge.And
Changes and modifications made by those skilled in the art do not depart from the spirit and scope of the present invention, then all should the right appended by the present invention want
In the protection domain asked.
