Description
Technical field
The present invention relates to a kind of sealing-off fixture of SMP connectors and sealing-off method.
Background technology
SMP type coaxial microband connectors are a kind of small-sized push-in type radio frequency connectors, with small volume, fast insert-pull, work
The characteristics of making bandwidth, is widely used in various microwave modules, and the chamber of microwave module is generally fixed in the form of welding
In body.In use, because a variety of causes causes the failure of some connector, its dismounting is a highly difficult thing,
And other destructions are likely to cause, and then cause the failure of whole microwave module.
In microwave module, SMP type coaxial microband connectors are to complete radiofrequency signal switching, the critical function of energy transmission
Element, is also the important input of microwave module, output interface.SMP is different according to linkage interface, is divided into cloudy head, first two positive shape
SMP type coaxial microband connectors on formula, usual microwave module use male interface.SMP type coaxial microband connectors
External diameter has two kinds of screw-type, light pillar type, is to be fixed in the form of welding on cavity.
The most common failure mode of SMP type coaxial microband connectors has following several：When the 1st, plugging, due to radial direction mismatch,
The mutual top pressure of inner wire, causes the inner wire of SMP type coaxial microband connectors to be broken；When the 2nd, welding, positioning is inaccurate, causes solder
Spread, internal and external conductor short circuit；3rd, the dielectric support failure of fixed inner wire.
After SMP types coaxial microband connector fails, it is necessary to changed.At present, SMP type coaxial microband connectors are removed
Method have three kinds：Overall heating, local heating, machining.Overall heating is to utilize heating furnace or warm table, by microwave mode
The temperature of block is increased to more than the temperature of solder thawing, further takes out SMP type coaxial microband connectors.Local heating is to utilize hot blast
The SMP type coaxial microband connectors of the Hot-blast Heating failure of rifle blowout, the temperature melted to solder.Machining is to utilize metal
The method of cutting, cuts into chip by SMP type coaxial microband connectors and removes.
The sealing-off method of overall heating, operation is fairly simple, but has the disadvantage：Melt when overall heating-up temperature is increased to solder
When more than temperature, not only the solder of failed coupler melts, and the solder of the connector of other normal functions also melts simultaneously, welding
The solder of micro strip can also receive influence, in addition, different materials are also differed with the elevated expansion of temperature in microwave module, may
Some are brought to destroy, such as potsherd ftractures.
Although heat gun can local heating, heat conduction efficiency is than relatively low, and rifle mouth must be just effective in the distance of very little
Really, the SMP type coaxial microband connectors of failure could be taken out, in this mistake after solder thawing, it is necessary to remove heat gun
Cheng Zhong, distributing for heat can cause temperature to reduce, so when usually used, can be adjusted to the blowing temperature of heat gun far above weldering
Expect more than melt temperature, which again increases the risk of other area damages of microwave module.Simultaneously as the wind pressure ratio of heat gun compared with
Greatly, the solder of thawing is easy to be blown into inside microwave module, brings short-circuit equivalent risk.
The sealing-off method of machining, the drawbacks of overall heating can be effectively prevented from, but operate more complicated：Select to close
Suitable installation way is fixed on lathe；Need to be accurately positioned failed coupler；During machining programming, dress is considered
Clamp the error of bit strip；It is the connector of screw thread for external diameter, after machine tooling, also wants pincers worker tapping again.Whole process is taken
, it is necessary to which exper ienced operating personnel complete during expenses of labour.
The content of the invention
Present invention seek to address that above mentioned problem is there is provided a kind of sealing-off fixture of SMP connectors and sealing-off method, it passes through
Electric iron carries out quick local heating, sealing-off to the SMP types coaxial microband connector failed in microwave module, to other regions
Influence it is small, and do not influenceed by microwave module size, shape, and the sealing-off method is simple, workable, the scope of application
Extensively, its technical scheme used is as follows：
A kind of sealing-off fixture of SMP connectors, it is characterised in that：Including sealing-off head and heating pole, sealing-off head by with
It is integrally formed in the head being connected with SMP coaxial microband adapters and for the afterbody being connected with heating pole, the head
Shape and the inner chamber of the outer conductor of SMP coaxial microband adapters match, breach groove, the head are machined with the head
End there is projection, the inner chamber of the outer conductor of the SMP coaxial microbands adapter has for the raised groove being caught in, the tail
The embedded SMA actuators in portion have internal thread, and the heating pole is mainly integrally formed by the first bar portion, the second bar portion and the 3rd bar portion, described
First bar portion matches with electric iron, what the internal thread being machined with the outer peripheral face of second bar portion with afterbody inner chamber matched
External screw thread, the 3rd bar portion has the accommodating cavity that the inner wire for SMP coaxial microband adapters is inserted.
On the basis of above-mentioned technical proposal, the breach groove is cross.
On the basis of above-mentioned technical proposal, the head hardness is HV390~410.
On the basis of above-mentioned technical proposal, the sealing-off head and heating pole are made by beryllium-bronze.
A kind of sealing-off method of SMP connectors, it is characterised in that：Using above-mentioned sealing-off fixture, first, by sealing-off head
Head is pressed into the inner chamber of the outer conductor of the SMP coaxial microband connectors of failure, and breach slot structure makes the head of sealing-off head have one
Fixed contraction, ability is opened, when sealing-off head is completely forced into, the projection at head port is opened, and is stuck in the connection of SMP coaxial microbands
It is spacing by the progress of hole shoulder in the groove of the inner chamber of the outer conductor of device；Then, heating pole is screwed into sealing-off head by connection screw thread, is turned
Dynamic sealing-off head is pressed on the inner face of SMP coaxial microband connectors until the end face of heating pole, and the end of sealing-off head is by tightly
Ground is clipped between heating pole and SMP coaxial microband connectors, and now three is closely connected；Then, by the another of heating pole
Electric iron and fixation, now, solder horn of the heating pole equivalent to electric iron are inserted in one end；Finally, electric iron electrified regulation is extremely welded
Material melts, in the case where still remaining powered on, and rotates or directly stirs heating pole, the SMP coaxial microband connectors of failure are taken
Go out.
The invention has the advantages that：The SMP type coaxial microband connectors failed in microwave module are entered by electric iron
The quick local heating of row, sealing-off, the influence to other regions is small, and is not influenceed by microwave module size, shape, and should
Sealing-off method is simple, workable, applied widely.
