Description
Technical field
The utility model relates to communication technical field, the tap of particularly a kind of close coupling.
Background technology
Wideband wireless mobile communication has become global communications industry and has developed one of industrial field of greatest concern, in the past few decades, along with the develop rapidly of modern wireless telecommunications, communication relevant industries, radio-frequency module has irreplaceable position in wireless communication technology, has a wide range of applications.
But the coupled modes existing defects of resonant column port at present, existing processing disadvantages has: solder joint is many, uncontrollable, easily causes intermodulation bad; Assembling is complicated, and complicated operation is high to required precision; Have welding hidden danger, solder joint also can impact the quality of product, there is the risk of rosin joint, disconnected weldering.Along with more and more higher bandwidth demand, the requirement of device fabrication to the technique that resonant column port is coupled is also more and more higher, close coupling, comparatively high coupling coefficient can be provided, easily realize comparatively broad passband port coupling, keep coupling coefficient consistency, the technical solution exempting to weld is needed badly most simultaneously.Meanwhile, equipment assembling process also demand fulfillment simply assemble, increase work efficiency, can be cost-saving.
Utility model content
The purpose of this utility model is the tap in order to solve a kind of close coupling that above-mentioned the deficiencies in the prior art provide.The tap mode of the program can realize superpower coupling; Do not have solder joint, intermodulation is good; Assembling is simple.
To achieve these goals, the tap of a kind of close coupling designed by the utility model, comprise mobile jib, heat-shrinkable T bush, resonant column and cavity, described resonant column and described heat-shrinkable T bush are arranged at inside cavity, described resonant column side is provided with heat-shrinkable T bush installing hole, described mobile jib is connected with described resonant column by described heat-shrinkable T bush, realizes close coupling.
Further, a kind of tap of close coupling, described heat-shrinkable T bush is insulating material.
Further, a kind of tap of close coupling, described mobile jib connects any type of radio frequency, microwave cable or joint.
The tap of a kind of close coupling that the utility model obtains, no-welding-spot, can not cause intermodulation bad; Assembling is simple, can realize quick assembling; Welding hidden danger, can not impact because of the quality of solder joint to product, there is not the risk of rosin joint, disconnected weldering.
The utility model has the advantage of: realize superpower coupling; Do not have solder joint, intermodulation is good; Assembling is simple.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of embodiment.
Fig. 2 is the plan structure schematic diagram of embodiment.
1 be mobile jib, 2 are heat-shrinkable T bushs, 3 are resonant columns, 4 are cavitys, 5 is heat-shrinkable T bush installing holes.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment:
As shown in the figure, a kind of tap of close coupling, comprise mobile jib 1, heat-shrinkable T bush 2, resonant column 3 and cavity 4, it is inner that described resonant column 3 and described heat-shrinkable T bush 2 are arranged at cavity 4, described resonant column 3 side is provided with heat-shrinkable T bush installing hole 5, and described mobile jib 1 is connected with described resonant column 3 by described heat-shrinkable T bush 2, realizes close coupling, described heat-shrinkable T bush 2 is insulating material, and described mobile jib 1 connects any type of radio frequency, microwave cable or joint.
The tap of a kind of close coupling that the present embodiment obtains, no-welding-spot, can not cause intermodulation bad; Assembling is simple, can realize quick assembling; Welding hidden danger, can not impact because of the quality of solder joint to product, there is not the risk of rosin joint, disconnected weldering.
The advantage of the present embodiment is: realize superpower coupling; Do not have solder joint, intermodulation is good; Assembling is simple.
For the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; its framework form can be flexible and changeable; just make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the utility model is determined by submitted to claims.
