Embodiment
In order to make those skilled in the art person understand better the utility model scheme, and above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with embodiment and embodiment accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, radio-frequency filter of the present utility model has the filter body 2 that is welded to each other and for the radome 4 of shielded signal, filter body 2 is rectangular structure, there are six faces, a face is electrode surface, a face is printed circuit drawing, radome 4 for cross section be the structure of " L " font, there are two faces, the back side welding of the electrode surface of face and filter body 2, another face suspends over against printed circuit drawing, puts to add a cover radome 4 after scolding tin and then cross stove both are welded together on filter body 2.
As Fig. 2, shown in 3, the assembling fixture that the utility model provides was assembled filter before crossing stove, it comprises square chuck body 6, the material of the utility model preferred fixture body 6 is aluminium alloy, heat conduction is fast, wherein the plane at regulation chuck body 6 places has orthogonal first direction 1 and second direction 3, in described chuck body 6 interval offer uniformly some be parallel to each other put part groove 8, put part groove 8 for placing filter body 2, put part groove 8 identical with the degree of depth of location notch 10, in described chuck body 6, put part groove 8 and also offer for the location notch 10 along first direction 1 location radome 4 for corresponding every, describedly put part groove 8 and location notch 10 side by side and the consistent setting in interval.Location notch 10 for place radome 4 suspend one side free end, the width value of location notch 10 on first direction 1 is exactly the changing value of spacing between radome 4 and filter body 2, that is to say that control the width value of location notch 10 on first direction 1 just can accurately control the consistency of overall filter performance in error range.Therefore after using assembling fixture of the present utility model, can control accurately the spacing between filter body 2 and radome 4, and during Batch assemblage, distance values is between the two stable, the finished product filtering characteristic high conformity of assembling, have simple in structure, packaging efficiency is high, the advantage of end properties high conformity.
Position for further fixed mask cover 4, described location notch 10 is interior offers along its bearing of trend the spacing hole 12 that several move along second direction 3 for limiting radome 4, and the contact pin that radome 4 suspends on the free end of one side is inserted and in spacing hole 12, just limited the movement of radome 4 along second direction 2.
Described put part groove 8 along being all protruding with the first protuberance 14 to its outside on the dual-side of first direction 1, it is along being all protruding with the second protuberance 16 to its outside on the dual-side of second direction 3, the edge of described the second protuberance 16 is concordant with the edge of location notch 10.Because the model of filter is varied, but the shape of radome 4 is consistent mostly, just different for the width of filter body 2 radomes 4 of different size, in assembly line, in the middle of one day, assemble possibly the filter of Multiple Type, this just there will be the unmatched situation of radome 4 and filter body 2 to produce, by being set, the first protuberance 14 and the second protuberance 16 remind the edge of assembler radome 4 should not exceed the first protuberance 14 and the second protuberance 16, if exceed the model mistake that radome 4 is just described.
In order further to improve packaging efficiency, at each, put the interior side near location notch 10 of part groove 8 and be equipped with a spacer 18, the rear assembler of spacer 18 is set only need to be sidelong the printed circuit diagram of filter body 2 into putting in part groove 8 in the face of accurate location notch 10, after unified putting well, erecting chuck body 6 makes the printed circuit drawing of filter body 2 be adjacent to spacer 18, spacing between spacer 18 and location notch 10 is exactly the spacing between filter body 2 and radome 4 like this, there is no need in order to reach spacing accurately and going one by one put meticulously.
As further improvement of the utility model, in putting part groove 8, each is equipped with a plurality of air-vents 20, air-vent 20 is ventilative use when finishing rear product introduction tin stove and weld for assembling, after setting up air-vent 20, the scolding tin between filter body 2 and radome 4 joint faces is heated evenly, weldability is good.
Above-described embodiment is preferably execution mode of the utility model; but execution mode of the present utility model is not limited by the examples; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify and all should be equivalent substitute mode, within being included in protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claim was defined.
