The present invention is further described with exemplary embodiment with reference to the accompanying drawing, wherein identical label in attached drawing
All refer to identical component.In addition, if the detailed description of known technology is for showing the invention is characterized in that unnecessary
, then it omits it.
Fig. 1~8 collectively illustrate phase shifter 100 of the invention, phase-shift circuit 2 including cavity 1, in cavity 1 and
Phase shifter dielectric-slab 3 (call in the following text " dielectric-slab) between cavity 1 and phase-shift circuit 2.
Cavity 1 includes bottom wall 12, upwardly extends a pair of sidewalls 11 to be formed along 12 longitudinally two sides of bottom wall and be connected across
This to the roof 10 on side wall 11,1 transverse ends of cavity it is at least open at one end to install circuit board 2, dielectric-slab 3 and allow Jie
Scutum 3 is stretched out and is moved in a straight line from the opening.
Dielectric-slab 3 is preferably tabular, and top is equipped with for supporting the protrusion on the roof 10 or bottom wall 12 of cavity 1
35, the top surface which is higher than dielectric-slab 3 is arranged.
Due to being equipped with protrusion 35 between the roof 10 or bottom wall 12 of dielectric-slab 3 and cavity 1, so that dielectric-slab 3 and cavity 1
Between be always tight fit relationship so that dielectric-slab 3 is not in pitch in transverse shifting process, it is hereby ensured that letters
The fluctuation of number index is small；Simultaneously as protrusion is 35 smaller with the contact surface of roof 10 or bottom wall 12, thus protrusion 35 and roof 10 or
Frictional force between bottom wall 12 is also smaller, such dielectric-slab 3 can successfully relative to 1 lateral displacement position of cavity, without
It will appear the phenomenon of mobile difficulty.
Preferably, protrusion 35 is square block or hemispherical.
Incorporated by reference to Fig. 3, in present embodiment, offered on dielectric-slab 3 through-hole 31 (to avoid dielectric-slab moving process by
The hereafter interference of the element on circuit board) or groove, the inner sidewall of through-hole 31 or groove is equipped with elastic arm 32, the end of elastic arm 32
Equipped with protrusion 35.When the dielectric-slab 3 is installed in cavity 1, protrusion 35 is suppressed roof 10 or bottom in dielectric-slab 3 and cavity 1
Between wall 12.
Fig. 3 illustrates the embodiment similar with a upper embodiment, the difference is that: the lengthwise side of dielectric-slab 3
Jagged 34 are opened up on wall, elastic arm 32 extends from the peripheral wall of notch 34 and formed.
