The opposite back side in front.Rack gear 2 has guide groove at its back side, for movably linearly guiding rack gear 2.Rack gear 2 its just
Having on face can one or more teeth portion corresponding with the teeth portion 17,18 of slide plate support 15,16.In the assembly of phase shifter package
In state, the teeth portion of slide plate support 15,16 is engaged with the teeth portion of rack gear 2.Rack gear 2 can drivingly be moved linearly, such as rack gear 2
It can linearly be driven by stepper motor.Rack gear 2 can be for example supported on individual rack gear support (not shown), and tooth
Support can be fixed on the shell of antenna for base station.As an alternative, rack gear 2 can also directly support on the housing, or
Say that shell itself may include rack gear support.
When rack gear 2 is for example driven by stepper motor, rack gear 2 moves linearly, and slide plate support 15,16 rotates with being driven,
Therefore slide plate printed circuit board 13,14 is rotated relative to corresponding main printed circuit board, is achieved in phase shift.
In Fig. 1 and embodiment shown in Fig. 2, two slide plate supports 15,16 are supported into respectively, can be turned independently of one another
Dynamic movement, and engaged and jointly rotational motion by with common rack gear 2.As an alternative, it is also possible that two slide plates
Support connects without relative rotation each other, and only one of them slide plate support has teeth portion, this teeth portion is nibbled with rack gear 2
It closes.In this embodiment, when rack gear 2 moves linearly, a first slide plate support among each slide plate support 15,16 turns
Dynamic movement, and a second slide plate support among each slide plate support 15,16 is forced to rotate together with the first slide plate support
Movement.In addition it is also possible that one teeth portion is arranged in the common shaft of two slide plate supports 15,16, such as occupies
It is arranged between two slide plate supports middlely.It is self-evident, more teeth portion can also be additionally provided in, to realize from rack gear
2 arrive the better power transmission of each slide plate support 15,16.This remodeling is also fallen within the protection scope of the utility model.
In the shown embodiment, it is respectively equipped with integrated teeth portion on two slide plate supports 15,16, and therefore each cunning
Piece support 15,16 without relative motion is connected with corresponding teeth portion.It is also possible that each teeth portion is configured to individual component,
It is connected with corresponding slide plate support 15,16, so that the rotation of teeth portion causes the corresponding of corresponding slide plate support 15,16 to turn
It is dynamic.
Bracket 1 includes multiple groups conductor guide portion 19.Such as one group of conductor is respectively equipped in the two sides of each main printed circuit board
Guide portion 19, therefore it is equipped with four groups of conductor guide portions 19 in total.Each conductor guide portion 19 for example may be embodied as, and receive corresponding
The clip or other structures part of conductor.Multiple conductors (such as coaxial cable) (not shown) can be brazed in corresponding main printing electricity
On the plate of road, and each conductor guide portion 19 can for example receive each coaxial cable.Bracket 1 the second arm 4 along vertical
To on the both ends in direction, a supporting leg 20 is substantially perpendicularly stretched out respectively, and each supporting leg has a lip 22, the lip
Portion is equipped with screw hole, for bracket 1 to be fastened on shell (not shown) by screw.
It can be such as seen best by Fig. 1, the first arm 3 and the second arm 4 of U-bracket are separated by gap 25.Multiple slide plates
Formula phase shifter includes clip, bias slide plate printed circuit board is used for, to compress it on main printed circuit board.This can have
Conducive to the consistent of the component for providing radiofrequency signal between the slide plate printed circuit board and main printed circuit board of slide sheet type phase shifter
Coupling.The side of clip is typically applied to slide plate support or slide plate printed circuit board, and the other side of clip acts on master
Printed circuit board or support plate (such as one piece of metal plate), main printed circuit board may be mounted in the support plate.
If two slide plate printed circuit boards are mounted on the reciprocal two sides of support plate, it may be difficult to utilize above-mentioned
Prop clip.For example, the bottom part of clip needs if prop clip is added to the phase shifter being mounted in support plate upper surface
It extends to below support plate.But on the position, prop clip may be with the phase shifter that is mounted on support plate lower surface
Operation interference.
It, can be in two differences by providing the U-bracket 1 having through the first and second separated arms 3,4 of gap 25
Arm on phase shifter is installed, each arm is used as corresponding support plate.Therefore, clip can be used together with each phase shifter,
Slide plate printed circuit board is pressed on main printed circuit board, because the clip for the first phase shifter will not interfere with the second phase shift
The operation of device.Gap 25 is also by each group conductor guide portion 19 for being used for the first phase shifter and each group conductor for being used for the second phase shifter
Guide portion 19 is spaced apart.
Such as best visible by Fig. 2, the first phase shifter can be towards first direction (such as upwards), and the second phase shifter
It can in the opposite direction (such as downwards).This can simplify the assembly of phase shifter package, be single-piece (one in U-bracket 1
Body formula) bracket embodiment in it is especially true.
Fig. 4 shows the signal of the phase shifter package with shielding part 21 of the another embodiment by the utility model
Figure.Here, the other component of phase shifter package can be identical as Fig. 1 and embodiment shown in Fig. 2 other than shielding part 21
Or it is similarly formed.Here, fastening shielding part 21 by screw in the outside of two phase shifters.
Finally, it is noted that above-described embodiment is used only for understanding the utility model, without the guarantor to the utility model
Shield range is construed as limiting.To those skilled in the art, modification can be made on the basis of the above embodiments, these are repaired
Change without departure from the protection scope of the utility model.The technical characteristic recorded in this application can in any combination, as long as this
It is not conflicting for combining, and all these combinations are all the technology contents recorded in this application.
