Abstract
The invention discloses an improved box type ceramic directional coupler. The improved box type ceramic directional coupler is characterized by comprising a box type housing with an opening on a top surface; stepped holes are formed on the two end surfaces of the housing body; wire connection terminals are arranged inside the stepped holes; a ceramic plate is installed inside the housing; four corners of the bottom of the housing are provided with stepped pin holes; pin assemblies are arranged inside the stepped pin holes; the pin assembly comprises a pin; an insulation ring sleeves the pin; the pin is coaxially fixed with an insulation sleeve ring through a positioning shaft shoulder; the top of the pin assembly is connected to the ceramic plate; a colloidal layer is loaded inside the housing; a cover plate is installed on the top surface of the housing; and the cover plate is installed on the housing body through a bolt. The improved box type ceramic directional coupler is small in volume, strong in an anti-interference capability and low in a production cost, and solves problems of looseness of pins and damaged ceramic plates due to heat expansion and cold contraction during usage of a coupler through improvement in structures of the housing and the pin.
Description
Technical field
The present invention relates to directional coupler, more particularly, to a kind of improved box ceramic directional coupler.
Background technology
Directional coupler is used in the passive component in frequency applications.Directional coupler is used for obtaining quantitation from main transmission line
RF signal power, this main transmission line in another circuit for analysis, or control primary path watt level purpose and will take
The high frequency signal transmission going out is to measurement port.Directional coupler is made up of two coupling lines, and this two coupling lines are arranged to distance
Distance make the signal being transmitted by main line be coupled to measure on coupling line number.
Directional coupler is used in widely applying, including：Signal waveform for measurement or monitoring or feedback and frequency are provided
Spectrum, or combination goes into or from the feeding of antenna, or the standing wave state of detection antenna, or provide for control circuit, system
Tap, or for send signal and receive signal intermediate conveyor level come to identify coupling main path signal after circuit shape
State.
With industrialized continuous development, small size, jumbo part, it has also become the development trend of certainty.In radio frequency
In application circuit, to pass through or detect powerful signal, and require good heat dispersion, necessarily will recognize that pottery coupling
Device.
Ceramic coupler has good directionality and capacity of resisting disturbance, and this bonder has transmission signal, isolation electricity
Road function.Compared with traditional transformer coupling isolator, photoelectrical coupler, this bonder have small volume, strong antijamming capability,
The advantages of low production cost.Ceramic coupler mainly should in the communications field, the ceramic coupler that makes of special process with common
Bonder is compared, and has notable in terms of the main performances such as power transmission capacity, heat conductivity, directionality index, capacity of resisting disturbance
Improve.
Content of the invention
It is an object of the invention to provide a kind of improved box ceramic directional coupler.
For achieving the above object, the technical scheme is that：A kind of improved box ceramic directional coupler, bag
Include the cassette shell of top surface opening, the both ends of the surface of described housing are respectively equipped with shoulder hole, and ladder in the hole is respectively provided with terminal stud；
The inside of described housing is equipped with ceramic wafer；Described housing bottom corner is respectively equipped with stepped pin holes, described pin holes
Inside it is respectively provided with contact pin component, described contact pin component includes contact pin, outside contact pin, is set with insulation sleeve ring, contact pin passes through positioning shaft shoulder
With insulation sleeve ring axial restraint, contact pin component top is connected with described ceramic wafer；Described enclosure interior fill gelatinous layer；
Equipped with cover plate, described cover plate is arranged on housing described housing top surface by screw.
A kind of preferred as the present invention, described insulation collar material is poly fourfluoroplastics.
The invention has the beneficial effects as follows：
1. the present invention have the advantages that small volume, strong antijamming capability, low production cost, through-put power big,.
Improved by the structure of housing, contact pin, solve bonder in use because effect of expanding with heat and contract with cold causes
Contact pin loosens, and damages the problem of ceramic wafer.
Brief description
Fig. 1 is the structural representation of the present invention.
Specific embodiment
Below in conjunction with accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described.
As shown in figure 1, a kind of improved box ceramic directional coupler, including the cassette shell 1 of top surface opening, described shell
The both ends of the surface of body 1 are respectively equipped with shoulder hole 2, are respectively provided with terminal stud 3 in shoulder hole 2；
The inside of described housing 1 is equipped with ceramic wafer 4；Described housing 1 bottom corner is respectively equipped with stepped pin holes 6, described slotting
It is respectively provided with contact pin component 5, described contact pin component 5 includes contact pin 501, is set with poly fourfluoroplastics outside contact pin 501 in pin hole 6
The insulation collar 502, contact pin 501 passes through positioning shaft shoulder 503 and the insulation collar 502 axial restraint, contact pin component 5 top and described pottery
The welding hole of porcelain plate 4 connects.In the prior art, common mode is, after contact pin is arranged on poly fourfluoroplastics insulated column, to pass through
Clear opening is coordinated with housing, and this connected mode is more close before not welding, but needs in the bonder course of processing
To heat through reflow machine, to receive the physical effect of thermal expansion shrinkage, cause the fit clearance between contact pin, insulated column, housing
Increase, when bonder plug, contact pin can produce loosening, outwards extracting or jacking ceramic wafer inwards, causing ceramic wafer damage
Bad.By being improved to stairstepping, setting the shaft shoulder on contact pin jack, greatly reduce the loosening problem between part, improve coupling
The serviceability of clutch.
Described housing 1 inside fill gelatinous layer（In figure is not shown）.
Described housing 1 top surface is arranged on housing 1 by screw 8 equipped with cover plate 7, described cover plate 7.
Described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the present invention
In embodiment, the every other enforcement that those of ordinary skill in the art are obtained under the premise of not making creative work
Example, broadly falls into the scope of protection of the invention.
