Abstract
The utility model relates to a capacitance coupling apparatus used for a waveguide filter, comprising an insulation support member, an insulation screw and a coupling copper sheet; the insulation support member is arranged under the coupling copper sheet; the insulation screw successively penetrates the coupling copper sheet and the insulation support member. Compared with prior arts, the capacitance coupling apparatus has the advantages of a simple structure, convenience in processing, high consistency, low costs, etc.
Description
Technical field
The utility model relates to a kind of capacitive coupling device, especially relates to a kind of capacitive coupling device that is used for waveguide filter.
Background technology
Capacitive coupling is claimed field coupled or Electrostatic Coupling again, is a kind of coupled modes that the existence owing to distributed capacitance produces.Along with developing rapidly of wireless telecommunication system, increasingly high to filter each item index request, in order to enhance productivity, reduce production costs.In traditional cavity body filter, what adopt usually is insulated support, and the mode of keeper and copper wire welding realizes capacitive coupling.
Because these parts are more loaded down with trivial details in processing, parts are more, and consistency is difficult to control in the manufacturing process, and very high to operating personnel's requirement, wayward product quality uprises production cost.
The utility model content
The purpose of the utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of simple in structure, easy to process, consistency is high, the lower-cost capacitive coupling device that is used for waveguide filter.
The purpose of the utility model can realize through following technical scheme:
A kind of capacitive coupling device that is used for waveguide filter is characterized in that, comprises insulated support, insulation screw, coupling copper sheet, and described insulated support is located at coupling copper sheet below, and described insulation screw passes coupling copper sheet and insulated support successively.
Described coupling copper sheet is a laminated structure, and is inverted U-shaped.
Described coupling copper sheet both sides are respectively equipped with the through hole corresponding with the filter adjustment screw near the bending place.
Described insulated support is a polyether-ether-ketone with the material of insulation screw.
Compared with prior art, the utility model adopts less parts, and is simple in structure, novel, practical, stable performance, reliable, high conformity, and lower to the requirement of machining accuracy, cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the rigging position sketch map of the utility model in waveguide filter.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
As shown in Figure 1; A kind of capacitive coupling device that is used for waveguide filter; Insulated support 2 is a polyether-ether-ketone with the material of insulation screw 3; The below of coupling copper sheet 1 centre is lined with insulated support 2, and insulation screw 3 passes coupling copper sheet 1 and insulated support 2, is used for being connected with the waveguide filter cavity.Coupling copper sheet 1 is a sheet, is bent into inverted U-shapedly through punching, and its bending place has two through holes, is respectively left through hole 11, right through hole 12, two tuning screws on the respective filter cover plate.
As shown in Figure 2, the whole capacitor coupling device is fixed on the cavity 5 of filter through insulation screw 3, and the bipod of inverted U-shaped coupling copper sheet 1 is installed downwards.Coupling copper sheet 1 does not directly contact with cavity 5 surfaces, and the centre is lined with one deck insulated support 2.First tuning screw 61, second tuning screw 62 are located at respectively on the cover plate 4 of filter, pass cover plate 4 backs and insert in the corresponding left through hole 11 of coupling copper sheets 1, the right through hole 12.During use, as long as first tuning screw 61, second tuning screw 62 on the rotation cover 4 are the size of adjustable condenser.
