Specific embodiment
Below in conjunction with the accompanying drawings, the technical solution of the utility model is specifically described.
The utility model provides a kind of follow-on cavity coupler, including a cavity 4 and is arranged in the cavity 4
First coupling bar 5 and the second coupling bar 6；One end of first coupling bar 5 is connected to and is embedded on the lateral wall of cavity first
First connector 1, the other end is connected to the second connector 3 being embedded on the lateral wall of cavity second；The one of second coupling bar 6
End is connected to the 3rd connector 2 being embedded on the lateral wall of cavity the 3rd, and the other end is connected to the 3rd inside sidewalls wall；First
The upper surface of the coupling bar 6 of coupling bar 5 and second is provided with first medium block 11, the first coupling bar 5 and the second coupling bar 6
Lower surface is provided with second medium block 9.
Further, in the present embodiment, the other end of the second coupling bar 6 is connected to a medium seat cushion 10, medium seat
Pad 10 is connected to the metal step 13 for being arranged at the 3rd inside sidewalls wall through a T-shaped power resistor 12.T-shaped power resistor passes through spiral shell
Silk is fixed on metal step.
Further, in this embodiment, first medium block and second medium block length, width, the first coupling bar and second
The length and cross-sectional width of coupling bar are determined according to the actual parameter of the cavity coupler.First and second medium block
It is FR4 dielectric-slabs.It is silver-plated that first coupling bar and the second coupling bar are copper bar, and medium seat cushion is white polyethylene.
Further, in the present embodiment, the first coupling bar 5 includes two ends and connects two ends and transversal
Face is the first male part 7 of rectangle；Second coupling bar turns shape end and connects this two and turns shape end and transversal including two
Face is the second male part 8 of rectangle；First male part be arranged in parallel with above-mentioned second male part, so that conduct on the first coupling bar
As the second male part parallel coupling of coupled zone on first male part and the second coupling bar of coupled zone.First male part 7
Width is consistent with the length of the second male part 8.By coupling bar 5 and 6, in the presence of medium block 9 and 11, cavity size is realized
Diminution and material cost reduction.
Above is preferred embodiment of the present utility model, all changes made according to technical solutions of the utility model are produced
