Detailed description of the invention
Wave filter uses the mode of " interdigital structure " to be different from " coaxially " mode of general employing, it is easy to wave filter and uses " in parallel " connected mode with power splitter, each several part is fully utilized, typically " coaxially " the design wave filter of mode uses " series connection " mode with power splitter so that under same volume, the progression of wave filter reduces and makes Out-of-band rejection be deteriorated.Therefore the present embodiment uses " in parallel " connected mode.
As shown in Figure 1, a kind of track traffic signal transceiver module merit filter-divider structure, it the present embodiment is 2.4G merit filter-divider, including power splitter 1 and wave filter 2, described power splitter 1 includes the cavity of power distributor 4 of an one end open and is arranged on the merit parallel circuit plate 5 inside described cavity of power distributor 4 base plate, multiple coupled resonance bars 7 that described wave filter 2 includes a main cavity surrounded by housing 6, is set in parallel in main chamber body 6, in two ends resonant rod 7 plane, it is perpendicular to plane and is respectively arranged with input and output end pieces 8；Described power splitter 1 and described wave filter 2 are overlapped mutually and are fixed together, and the input and output end pieces 8 of described wave filter 2 is connected through described cavity of power distributor 4 base plate with the circuit in parallel on described merit parallel circuit plate.
As shown in Figure 2, in the present embodiment: wave filter 2 uses the wave filter of a kind of interdigital structure, input and output end pieces 8 is two round bars, this round bar is vertically installed on coupled resonance bar 7, round bar extends to cavity of power distributor 4 base plate direction from coupling resonant rod 7, being different from prior art the wave filter of interdigital structure as shown in Figure 4, parts 8 are not to be vertically installed on coupled resonance bar 7, but concora crush is on coupled resonance bar 7；Therefore, its input/output terminal of the present embodiment structure is arranged on the both sides frame of wave filter and extends to both sides.This kind of structure can make power splitter 1 and wave filter 2 be overlapped mutually and be fixed together, such as same " in parallel " structure (Fig. 1), rather than tiling side by side compared with power splitter in technology 1 and wave filter 2 as shown in Figure 5 links together, as same " is connected " structure, the present embodiment structure makes the progression of wave filter under same volume reduce and make Out-of-band rejection be deteriorated.
As shown in Figure 3, the cylinder 9 of screw it is provided with inside described cavity of power distributor 4 base plate, it is provided with, on described merit parallel circuit plate 5, the circular hole matched with cylinder 9, described merit parallel circuit plate 5 is inserted in cylinder 9 by circular hole, one compression leg 10 with holes is inserted in cylinder 9 to be pushed down merit parallel circuit plate 5 and is fixed on cavity of power distributor 4 base plate by merit parallel circuit plate 5, and fixes with screw 11.The thickness of described cavity of power distributor 4 base plate is not more than 1mm.Owing to the bottom thickness of merit parallel circuit plate Yu the assembling of cavity only has 1mm, that therefore commonly uses beats the mode unworkable (ripe title " subtraction ") that screw is fixing on bottom surface, therefore the upwards some cylinders of milling in bottom surface, be equivalent to local and thicken bottom surface (ripe title " addition "), tapping on cylinder, then punches on the corresponding position of circuit board, and during circuit board assembling, cylinder is through circular hole, it is enclosed within cylinder with compression leg again, uses screw-driving.
As in figure 2 it is shown, the contact surface that main cavity 6 frame of described wave filter 2 and cavity of power distributor 4 are stacked is provided with groove 12.The degree of depth of described groove 12 is more than or equal to 0.1mm.Described groove 12 is the enclosed construction of the frame setting in a week around wave filter.Filter main body fitting surface is milled with the technology groove of the deep 0.1mm of one fixed width.There are two effects: 1, reduce contact surface when other structural members assemble with wave filter, thus ensure electrically to seal；2, the most extraneous steam, due to the existence of groove, had both extended access path, has again and gathers steam and be not easily accessible filtering cavity and break the effect of outdoor electrical performance.
Being fixed together as it is shown in figure 1, the present embodiment median filter 2 superposes with power splitter 1, the outside of wave filter 2 is provided with cover plate 3, and the outside of cover plate 3 is provided with lower shoe 13；The opposite side of power splitter 1 is provided with nameplate 14.
