Abstract
A kind of fast pressure microwave jointing, belongs to the application field of microwave measurement and microwave equipment, is related to microwave jointing (microwave joint).Traditional microwave jointing use when be usually attached by welding.This mode has Railway Project to need to consider.First, solder joint will affect the microwave property of junction；Second, crossover sub needs frequent replacement, and the consistency of welding is difficult to ensure；Third, frequent welding will cause the damage of crossover sub and the damage of welding position circuit substrate.Therefore, suitable microwave jointing is designed to substitute traditional needs by the microwave jointing of welding realization be significantly.Fast pressure microwave jointing of the invention is pushed by inner conductor of the connector lower platen to crossover sub, the inner conductor of crossover sub is allowed to be tightly pressed against on pcb board, guarantee that junction has good electrical connection, crossover sub is realized conveniently to replace, and connector and the circuit substrate of junction are substantially unaffected, and greatly reduce application cost.
Description
Technical field
The invention belongs to the application fields of microwave measurement and microwave equipment, are related to microwave jointing (microwave
Joint).
Background technique
Microwave adapter coupling is the critical elements in microwave test and microwave equipment.Its effect is two characteristic impedances
The structure that identical transmission structure connects.Its performance superiority and inferiority directly affects the globality of microwave test and microwave equipment
Energy.Especially the integrated miniaturization of microwave circuit, the size at microwave junction position persistently reduce, the company of microwave crossover sub
It connects processing and needs even closer processing.
Traditional microwave crossover sub is usually to be attached by welding when in use.This mode has several
Problem needs to consider.First, solder joint will affect the microwave property of junction；Second, crossover sub needs frequent replacement, welding
Consistency be difficult to ensure；Third, frequent welding will cause the damage of crossover sub and the damage of welding position circuit substrate
Wound.Fast pressure microwave jointing of the invention is pushed by inner conductor of the connector lower platen to crossover sub, and conversion is allowed to connect
The inner conductor of head is tightly pressed against on pcb board, guarantees that junction has good electrical connection, it is convenient and efficient to realize crossover sub
Replacement, and connector and the circuit substrate of junction are substantially unaffected, and greatly reduce application cost.
Summary of the invention
The present invention solves existing microwave crossover sub welding, frequent replacement etc. and exists by introducing connector hold-down devices
The above problem.
Technical scheme is as follows:
A kind of fast pressure microwave jointing is as shown in Fig. 1, including connector lower platen 1, inner conductor pressing member 2, connector mounting plate
3, crossover sub 4, crossover sub inner conductor 5.Pressure jointing is characterized in that fastly as illustrated, under the inner conductor that connector introduces
Casting die can quickly make adapter inner conductor and circuit substrate circuit connection in the case where welding, this is advantageously reduced frequently
Welding is damaged caused by crossover sub and circuit substrate, and convenient and efficient, switching performance is excellent.Connector lower platen is adjustable
The pressure that inner conductor pressing member pushes crossover sub inner conductor can obtain good consistency effect.
The fast pressure microwave jointing specific implementation process of one kind is: as shown in Fig. 2, by specific implementation example to this
Invention is described in further detail.Inner conductor pressing member 2 is connected by adjustable screw in connector lower platen 1, under connector
Pressing plate 1, inner conductor pressing member 2, crossover sub 4 are connected by screw with connector mounting plate 3, under connector lower platen 1, inner conductor
Casting die 2, crossover sub 4 are connected by screw with circuit substrate 6 with the fast pressure microwave jointing A that connector mounting plate 3 is set up,
In, crossover sub inner conductor 5 is connected with circuit substrate microstrip line 7, by adjusting inner conductor pressing member 2 and family's head lower platen 1
The adjustable crossover sub inner conductor of adjustable screw 5 and the pressure of 7 junction of circuit substrate microstrip line, the crossover sub made connect
Meeting place has good electrical contact.When needing replacing crossover sub, it is only necessary to by crossover sub and microwave circuit base
The screw that plate 6 connects is backed out and can quickly and easily be replaced.
The utility model has the advantages that
One, inner conductor pressing member can quickly make adapter inner conductor and circuit substrate circuit connection in the case where welding,
Frequently welding damage caused by crossover sub and circuit substrate is greatly reduced, use cost is reduced；
Two, the pressure that the adjustable inner conductor pressing member of connector lower platen pushes crossover sub inner conductor can obtain good
Connection consistency effect.

Wherein, 1 be connector lower platen, 2 be inner conductor pressing member, 3 be connector mounting plate, 4 be crossover sub, 5 be conversion
Connector inner conductor.
Attached drawing 2 is fast pressure microwave jointing installation example.
Wherein, A is fast pressure microwave jointing, and B is microstrip circuit.
Specific embodiment
A kind of fast pressure microwave jointing, as shown in Fig. 1, including connector lower platen 1, inner conductor pressing member 2, connector peace
Loading board 3, crossover sub 4, crossover sub inner conductor 5.Inner conductor pressing member 2 is by adjustable screw in 1 phase of connector lower platen
Connection, connector lower platen 1, inner conductor pressing member 2, crossover sub 4 are connected by screw with connector mounting plate 3, and connector pushes
The fast pressure microwave jointing A that plate 1, inner conductor pressing member 2, crossover sub 4 and connector mounting plate 3 are set up passes through screw and circuit
Substrate 6 connects, wherein crossover sub inner conductor 5 is connected with circuit substrate microstrip line 7, by adjust inner conductor pressing member 2 with
The pressure of the adjustable screw of family's head lower platen 1 adjustable crossover sub inner conductor 5 and 7 junction of circuit substrate microstrip line, makes
Crossover sub junction have good electrical contact.
Fast pressure microwave jointing provided by the invention can facilitate the quick-replaceable of crossover sub, and butt joint and connect
Very little is lost in head junction circuit substrate, and the electric property consistency of junction is good.
