Abstract
Disclosed in the invention is a novel broadband filter tap comprising a resonance rod (6), a cavity (4), an aluminum cover plate (3), a silver-plated copper screw (2) and a radio frequency connector (5). The radio frequency connector (5) includes a radio frequency connector inner core (8); and a casing tube is arranged on the radio frequency connector inner core (8). A through hole (10) is formed in the resonance rod (6); the radio frequency connector inner core (8) is connected with the resonance rod (6) by the through hole (10); and the silver-plated copper screw (2) extends into the resonance rod (6). According to the filter tap, the filter bandwidth is effectively extended, so that multiple signals on one filter device can be realized well; tin soldering of the tap and the connector is not employed, so that the intermodulation index of the cavity filter can be well improved and the overall quality of the product can be enhanced; and the assembling is simple and the manual cost is saved.
Description
Technical field
The present invention relates to filter field, particularly a kind of Wideband filter tap.
Background technology
Along with the development of the communication technology, the signal of communication of multi-modulation scheme apply by masses, so, according to original technological means, just need multiple communication equipment to realize the transmission of signal, just cause the waste of resource, but adopt existing technology, multiple Design of Signal has very large difficulty on a cavity body filter.As shown in Figure 1, existing broadband filter tap silver-coated copper wire is directly welded on above resonant rod and realizes, and adopts this kind of mode to realize the tap of filter, there is following shortcoming: 1. weld silver-coated copper wire realizable filter limited bandwidth; 2. add cost of labor; 3. the bad realization of product intermodulation index and bad control etc.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of Wideband filter tap is provided, the effective widening filter bandwidth of this filter tap, the realization of multiple signal on a filter apparatus is better solved, scolding tin is not adopted to weld between tap with connector, the intermodulation index of cavity body filter is well improved, and its assembling is simple, saves cost of labor.
The object of the invention is to be achieved through the following technical solutions: a kind of Wideband filter tap, it comprises resonant rod, cavity, Aluminum cover, silver-plated copper screw and radio frequency connector, described radio frequency connector comprises radio frequency connector inner core, radio frequency connector inner core is provided with sleeve pipe, described resonant rod is also provided with through hole, radio frequency connector inner core is connected with resonant rod by through hole, and silver-plated copper screw stretches into resonant rod.
Described Aluminum cover is fixed on cavity by stainless steel pan head screw.
Described sleeve pipe is PTFE medium sleeve pipe.
Described resonant rod is fixed on cavity by stainless steel sunk screw.
Described silver-plated copper screw is provided with screw thread, and is connected with Aluminum cover by screw thread, silver-plated copper screw is fixed on Aluminum cover by nut.
The invention has the beneficial effects as follows: the invention provides a kind of Wideband filter tap, this filter tap has effectively widened filter bandwidht, the realization of multiple signal on a filter apparatus is better solved, scolding tin is not adopted to weld between tap with connector, the intermodulation index of cavity body filter is well improved, improve the quality of integral product, and its assembling is simple, saves cost of labor.
