Screw rod, can basis close to the lower end of the metal Coupling piece or resonance mobile jib between metal Coupling piece and resonance mobile jib
Need to be set as specific shape to realize that specific coupling area is e.g. set as flat structure or specific column structure.
The adoptable adjusting method of the stiffness of coupling of the coupled structure, for example, adjusting gold by the diameter for changing adjusting screw rod
Belong to the coupling area of coupling piece and adjusting screw rod, the coupling area of resonance mobile jib and adjusting screw rod, by adjusting adjusting screw rod
Highly, change the size of face between coupled structure, i.e. coupling area size, reached with this change metal Coupling piece with it is humorous
Stiffness of coupling adjustable range size between vibration mobile jib: the coupling area of adjusting screw rod is bigger, and stiffness of coupling adjustable range is bigger.
In addition to the above regulating measure, this coupled structure in resonance mobile jib side is located at for metal Coupling piece, coupling is strong
Degree adjustable range can also be realized by adjusting the thickness of metal Coupling piece: the thickness of metal Coupling piece is bigger, coupling area
Bigger, then stiffness of coupling adjustable range is bigger.
Fig. 1 shows a kind of birds-eye perspective of specific communication headend equipment component.As shown in Figure 1, the communication front end
Part of appliance has a cavity 5, and cover board 6 is fixed on cavity 5 by cover board mounting screw 7 can form a closed appearance
Chamber.As shown in Figure 1, there are four resonant rods 2 for setting in cavity 5, each resonant rod 2 includes the resonance mobile jib for resonance.
Resonance mobile jib in the present embodiment is the tubular structure of upper end opening, can pass through the resonant rod mounting screw in insertion tubular structure
11 are fixed on resonant rod 2 height that resonant rod 2 in cavity 5 and is adjusted, and realize the relatively described metal Coupling piece, adjust spiral shell
The adjusting of the coupling area of bar.The present embodiment communicates metal Coupling piece 1 set in the cavity 5 of headend equipment component, root
It requires to distinguish non-contact couple with two or more resonant rods 2 respectively according to product design.As shown in Figure 1, the communication headend equipment
Component tool is fixed on cavity 5 by connector mounting screw 9 respectively there are two the connector 8 for carrying out signal transmission with other component
On side wall.The one end of connector 8 in cavity 5 includes a conductor rods, and the end of conductor rods is connected with conductor disc, the disk of conductor disc
Facing towards the resonance mobile jib of corresponding resonant rod 2, pass through the non-contact biography for coupling realization electromagnetic signal of conductor disc and resonant rod 2
It is defeated.Adjusting screw rod 10 is fixed on cover board 6, protrude into the intracorporal resonant rod 2 of the chamber and the opposite gap of metal Coupling piece 1 it
Between, it passes through cover board 6 and is coupled with each resonant rod 2 and metal Coupling piece 1, since the upper end of adjusting screw rod 10 is realized by adjusting nut
Adjustable fixation therefore can be by selecting the size of adjusting screw rod 10 and protruding into position, the depth adjustment communication headend equipment
The working frequency and coupling state of component.
As shown in Figure 1, 2, 3, the middle section of the metal Coupling piece 1 in the present embodiment is set as the shape of strip, and both ends are set
Two semi-circular sheet metals are set to, global shape requires according to properties of product and had similar to double (end) wrench, specific size parameter
Body design.Each semi-circular sheet metal is non-contactly covered respectively on the resonance mobile jib of a resonant rod 2, and in metal Coupling piece
There are enough space adjusting screw rods 10 between resonance mobile jib；Adjusting screw rod 10 is located at resonance mobile jib and metal Coupling piece 1
Between；In order to enable metal Coupling piece 1 is capable of fixing in cavity 5 and not direct with cavity 5, resonant rod 2, adjusting screw rod 10
It contacts, is consolidated metal Coupling piece 1 one group of insulated screw 3 and insulation spacer 4 made of nonmetallic materials in the present embodiment
Due in cavity 5.
According to Fig. 1,2,3 it is found that the resonance mobile jib of adjusting screw rod 10 and metal Coupling piece 1, resonant rod 2 in the present embodiment
Between there is stronger coupling.According to basic electromagnetic theory it is found that adjusting screw rod 10 is on cavity wall direction
The resonance mobile jib of projection and resonant rod 2 has overlapped area, i.e. coupling area between the projection on cavity wall direction；
Adjusting screw rod 10 is equally deposited between the projection on cavity wall direction in the projection on cavity wall direction and metal Coupling piece 1
In overlapped coupling area.The resonance mobile jib of above-mentioned coupling area and adjusting screw rod 10 and resonant rod 2 is at cavity bottom
Projector distance distance in portion, adjusting screw rod 10 and projector distance of the metal Coupling piece 1 on cavity bottom, adjusting screw rod 10
Diameter, the thickness of metal Coupling piece 1, these factors are coupled between adjusting screw rod 10 and resonant rod 2, metal Coupling piece 1
The strength relationship of effect is maximum, therefore required stiffness of coupling can be obtained by the adjusting to these factors.
Wherein, the overlapping area projected between adjusting screw rod 10 and the resonance mobile jib of resonant rod 2 is bigger, then adjusting screw rod 10
Stiffness of coupling between resonant rod 2 is bigger, and on the contrary then coupling dies down.The adjusting of the parameter can be big by changing adjusting screw rod diameter
Small and resonance rod-shape and the depth of cavity is protruded into adjust.
The overlapping area projected between adjusting screw rod 10 and metal Coupling piece 1 is bigger, then adjusting screw rod 10 and metal Coupling
Stiffness of coupling between piece 1 is bigger, and on the contrary then coupling dies down.This coupling area can be big by changing the diameter of adjusting screw rod 10
It is small, change the stiffness of coupling between adjusting screw rod 10 and resonance mobile jib, between adjusting screw rod 10 and metal Coupling piece 1, to change indirectly
Become the stiffness of coupling between metal Coupling piece 1 and resonant rod 2.
In addition to this, various other feasible regulative modes can also be used, for example, the annular in semi-circular sheet metal is wide
Degree, semi-ring radian and thickness it is certain under conditions of, stiffness of coupling can be adjusted by adjusting the position of adjusting screw rod 10, adjusted
Screw rod 10 is closer at a distance from the inner ring of semi-circular sheet metal, resonance mobile jib, and stiffness of coupling is bigger.
By embodiments above it is found that technical solution of the present invention can greatly improve coupling by above-mentioned adjustment structure
Stiffness of coupling adjustable extent between component and resonant rod, and provide a variety of simple and effective stiffness of coupling regulative modes.
The structure of coupled structure of the present invention is simple, and cost of implementation is cheap, can be widely applied to the communication such as duplexer, combiner, filter
Headend equipment component, has highly application value.
The above is only embodiments of the present invention, and the description thereof is more specific and detailed, and but it cannot be understood as right
The limitation of the invention patent range.It should be pointed out that for those of ordinary skill in the art, not departing from the present invention
Under the premise of design, various modifications and improvements can be made, these are all belonged to the scope of protection of the present invention.
