1314 welding, can further promote the reliability that metal cavity 110 is electrically connected with ground plane 133.Moreover, because metallization card slot
1312 run through substrate 131, therefore welding operation can carry out in substrate 131 backwards to the side of metal cavity 110.At this point, metal cavity
110 and phase-shift circuit 120 to welding position formation keep away position, consequently facilitating operation.
In addition, multiple signal terminals 121 are electrically connected with feeder line 135.Therefore, electric signal can feeder line 135 with
It is conducted between phase-shift circuit 120.Wherein, being arranged altogether due to metal cavity 110 and feeding network plate 130, and signal terminal
121 are electrically connected with feeder line 135 again, therefore play the role of being equivalent to traditional coaxial feeder.Therefore, phase shift feeder equipment
100 without coaxial feeder, can realize that feeder line 135 feeds phase-shift circuit 120.
For existing phase shifter, due to realizing phase-shift circuit 120 and feeder line 135 without coaxial feeder
Electrical connection.Therefore, on the outer wall of metal cavity 110 without setting installation coaxial feeder wiring groove, while avoid because
Coaxial feeder need to be welded with the wiring groove of 110 outer wall of metal cavity and generally existing welding efficiency is low, welding quality is poor
Problem is conducive to the electric property for promoting phase shift feeder equipment 100.
It can be realized and be electrically connected by modes such as welding, conducting wire connection, grafting between signal terminal 121 and feeder line 135.
In the present embodiment, substrate 131 offers multiple power feed holes 1313 through substrate 131, and each power feed hole 1313 is backwards to gold
The edge for belonging to 110 side of cavity is provided with the feed pad 1315 being electrically connected with feeder line 135, and signal terminal 121 is through feeding
Hole 1313 is electrically connected with feed pad 1315.
Specifically, signal terminal 121 can be led to substrate 131 backwards to 110 side of metal cavity by power feed hole 1313.Root
According to different demands, power feed hole 1313 can be metallization VIA, can also be common through-hole.At this point, no matter being made using which kind of mode
Signal terminal 121 is electrically connected with feed pad 1315, since metal cavity 110 and phase-shift circuit 120 can be to the portions of electrical connection
Position forms and keeps away position, therefore easy to operate.
Further, in the present embodiment, the position corresponding with multiple power feed holes 1313 of phase-shift circuit 120 is formed with multiple
Foot 123, multiple signal terminals 121 are located on multiple stabilizer blades 123, and stabilizer blade 123 is arranged in power feed hole 1313 and welds with feed
Disk 1315 welds.
Specifically, stabilizer blade 123 and phase-shift circuit 120 are integrally formed, such as the extension protrusion at pcb board edge.Stabilizer blade 123 with
Power feed hole 1313 cooperates the quick positioning, it can be achieved that signal terminal 121 and feeder line 135.Moreover, being drawn by stabilizer blade 123
Signal terminal 121, therefore only need to carry out primary welding operation at feed pad 1315, to reduce welding times.In addition,
Due to the position-limiting action of power feed hole 1313, stabilizer blade 123 is not easily to fall off, to can also promote phase-shift circuit 120 and feeder line 135
The reliability of electrical connection.
It is electrically connected it should be pointed out that other modes realization also can be used between phase-shift circuit 120 and feeder line 135.
For example, the phase shift feeder equipment 100 in embodiment illustrated in fig. 4 two uses feed wire 150 to connect phase-shift circuit 120 and feedback
Electric line 135.
In example 2, the phase shift feeder equipment 100 in phase shift feeder equipment 100 and the utility model preferred embodiment
Difference be: phase shift feeder equipment 100 further includes the feed wire 150 for being arranged in power feed hole 1313.The one of feed wire 150
End is welded with signal terminal 121, and the other end and feed pad 1315 are welded.
Specifically, the feed wire 150 can be metal conductor rod, metallic conductor piece or PCB circuit board.When feed is led
When passing through power feed hole 1313 bending, distortion can occur for line 150.Therefore, though multiple signal terminals 121 not with multiple feeds
Hole 1313 is aligned one by one, can also smoothly realize electrical connection eventually by feed wire 150.That is, the side of above-mentioned electrical connection
Requirement of the formula for the 131 aperture precision of assembly precision and substrate of phase-shift circuit 120 is relatively low, and it is good that this is conducive to promotion product
Rate.
Further, in the present embodiment, one end of feed wire 150 is formed with limited cap 151, on signal terminal 121
Through-hole (not shown) is offered, feed wire 150 is arranged in through-hole and abuts limited cap 151 with the edge of through-hole.
Limited cap 151 is relatively large in diameter, so that the longitudinal cross-section of feed wire 150 is T-shaped.Weld feed wire 150
When, it can first will be far from the through-hole of one end insertion signal terminal 121 of limited cap 151, feed wire 150 can be in limited cap 151
It avoids skidding off under blocking, consequently facilitating assembly.
