Background technology
Mobile communications network covering in, microwave device be it is indispensable, common microwave device mainly have phase shifter,
Power splitter, wave filter, coupler, duplexer etc., the quality of its performance directly influence the covering quality of network.Microwave device master
To include the components such as Microwave Net circuit and cavity.To lift the stability and reliability of Antenna Operation, it is desirable to which microwave device exists
Installation on antenna-reflected plate is to stablize, is reliable.To avoid passive intermodulation (i.e. PIM) problem, microwave device not with antenna
Reflecting plate directly contacts, and often designs a kind of plastic fastener of insulation, and side is first connected on the cavity of the microwave device,
Opposite side is reconnected on antenna-reflected plate, and plastic fastener is connected with cavity, and at least one location hole is often preset on cavity,
It is corresponding, at least one positioning column is preset on plastic fastener.Determine plastic fastener on cavity by this point
Position.But the shielding of the electric property and cavity in view of microwave device, the location hole cannot be opened too greatly, together
When, since the wall thickness of cavity is relatively thin, the projecting height of the positioning column can not be higher than the wall thickness of the cavity, excessive to influence chamber
The slip of in-vivo medium, during installation, it is necessary to which plastic fastener is placed in cavity positioning before the positioning column enters the location hole
Near hole, judge further according to naked eyes and micro-judgment, make plastic fastener rotation while be held on cavity, the positioning column
Also the location hole is entered.Certainly, since location hole is smaller and positioning column is shorter, it may appear that plastic fastener is clamped on cavity fixed
The situation that position does not align, at this time more troublesome to plastic fastener progress position adjustment.
Still further aspect, is the continuity for not influencing cavity shielding and electric property, and location hole can not be placed in microwave device
The surface of circuit in part, the excessive perforate on cavity, by milling cutter hole milling through cavity wall thickness to cavity inner wall, can including
Wall produces countless trickle burrs, if the burr, which is dealt with improperly, can equally produce PIM problems, meanwhile, the burr of inner side is compared to outer
The burr of side, deals with increasingly difficult.This undoubtedly adds the cost of antenna.
It can be seen from the above that also there are certain defect for the prior art.
