Description
Technical field
The utility model is related to communication antenna technical field, more particularly to a kind of high frequency die casting oscillator insulation spacer.
Background technology
Influence antenna third order intermodulation (PM) one of key factor be metal with metal joint gap at small gap, small
The micro discharge phenomenon of burr, and the original design of antenna high frequency oscillator assembling is that high frequency die casting oscillator is (general by trip bolt
It is logical play plain cushion screw or it is resistance to fall screw) it is fixed, directly contacted with reflection plate face, except the oscillator pin at screw fastening can be with reflection
Plate contact is outer, and oscillator bottom can also contact with reflecting plate, and contact area is larger.
The original design is more or less at contact surface due to reflecting plate and the flatness problems with respect of the objective reality of oscillator bottom surface
Can there is minim gap, and then cause tail end to discharge, cause PM to deteriorate；Transportation is had enough to meet the need simultaneously has the cycle or aperiodic
Vibrations, screw may be loosened or resilience, and oscillator bottom can be caused to be collided with reflecting plate, and plane roughness becomes big, softer reflection
Plate easily produces small burr, causes micro- end to discharge, and then causes third order intermodulation (PM) to deteriorate.
The content of the invention
The purpose of this utility model is, regarding to the issue above, there is provided a kind of high frequency die casting oscillator insulation spacer.
The technical scheme that the utility model is used to achieve the above object for：
A kind of high frequency die casting oscillator insulation spacer, including its shim body, the shim body include upper surface and lower surface,
The upper surface is provided with the first depression, and the lower surface is provided with the second depression, convex is provided with first recessed central, in this
Convex is provided with oscillator trip bolt through hole through the shim body, the convex be formed around several oscillator pin vias,
Several U-shaped holes and several oscillator stud location holes, screw hole column is provided with the lower surface or so two ends through shim body,
In the upper surface, the correspondence screw hole column is provided with screw, and it is fixed to be provided with oscillator stud location hole described in lower surface correspondence one
Position post.
The shim body is rounded.
The oscillator pin number of vias is two, and the U-shaped hole number is two.
The shim body is symmetrical, and the oscillator pin via is symmetrical arranged with the U-shaped Kong Jun, the oscillator column
