Definitions
- the invention relates to a cavity resonator of a prismatic housing made in one piece along its edges connected, plan metal plates with openings at least for coupling and decoupling of RF energy.
- Such cavity resonators belong to this created on this side State of the art and are for example as usually multi-circuit, transmit-side bandpass filter for RF powers of several hundred watts up in high Megahertz range or used in the gigahertz range.
- the prismatic housing then consists of several chambers of the same dimensions along their side surfaces e.g. in I-, L- or U-form strung together as well as mechanically and electrically connected to each other. Each chamber forms a filter circuit.
- the chambers are designed or made as hollow castings made of comparatively thick metal plates, alternatively made of thick-walled metal hollow profiles along their edges soldered and / or welded and before or after, before fitting the chamber lid, inside galvanic coppered or silvered.
- Cavity resonators is therefore a complex manufacturing technology required.
- a cavity resonator which consists of a tube with a bottom and a lid, each welded to the tube.
- WO-A1-9825443 is a prismatic housing with Openings for conducted coupling and decoupling known by RF energy.
- the housing includes one in theirs Edge region spaced slots having Base plate and a hood whose resting on the bottom plate Side edges projecting and the slots of the Bottom plate has sweeping tabs.
- the invention is based on the object, a cavity resonator the introductory specified genus, the with at least the same mechanical stability and electrical Quality is considerably cheaper to produce.
- Such plates can be made of corresponding semi-finished boards by punching and / or by electron or laser beam cutting with very small dimensional tolerances too Produce costs that are insignificant over the cost of the cutting of the plates of the known cavity resonators lie.
- the applied connection technology allows it, all the side walls, the floor, the lid and possibly also the inner walls of a multiple chambers Cavity resonator to produce in one piece and the chambers only by appropriate intermediate walls or To create intermediate wall spaces instead of several, as before each for itself complete chambers - in sau Vietnamese Resonators along orthogonal axes - juxtaposed and having to connect with each other.
- the tabs are according to the thickness of the Undercut slotted plate.
- the undercut This facilitates the mating of the plates subsequent deformation of the tabs.
- An advantageous embodiment is characterized in that the width of the undercuts from the side flap edge in the direction of the remaining Laschensteges of a value greater than the thickness of the The slotted plate is, to a value that is at most equal to the thickness of the plate accessed, decreases and that the tabs are restricted.
- the cabinets The tabs thus inevitably leads to a correct position Clamping together each connected in this way Plates. This will ensure that so connected plates except for a given soldering gap be placed in the correct position.
- six-circuit filter consists of a prismatic housing with continuous Exterior walls 1 to 6 of metal plates and inner partitions 7, 8 and 9.
- the filter thus comprises six chambers, from to see the chambers 10, 11 and 12 in Fig. 1 in section are.
- the first and the last chamber have a coupling connection 20 and a decoupling connection 21.
- Each of Chambers is equipped with Abstimmschiebern such as 30, 31 and 32.
- the chambers are here via coupling lines like 40 and 41 not closely related construction coupled together.
- All metal plates, including the inner partitions 7, 8 and 9, are connected together, as in Figures 3 and 4 is shown in more detail.
- the side plate 2 has one over its side edge 2a (see Fig. 4) projecting tab 2.1.
- These tabs passes through in accordance with FIG. 3 in the cover plate. 6 trained slot 6.1.
- the tab 2.1 is of both Undercut pages.
- the width of the symmetrical Undercuts H takes from the side flap edges 2.1a and 2.1b towards the remaining tab web 2.1c of a value greater than the thickness d of the side plate 2 is, to a value that is at most equal to this Thickness d is off.
- the final soldering is not shown.
- To produce of a defined soldering gap can be the margins the tabs having plates with integral, to the Tabs equiaxed, almost point-like projections with e.g. be provided a height of 0.1 mm, in particular when laser cutting from large panels without additional costs let generate.
- the inner partitions such as e.g. the partitions 7 to 9 in Figs. 1 and 2, assembled to a so-called. Gefache, then the outer walls, i. the side walls, the floor and the lid, to be put on.
- Figures 5 and 6 illustrate that the previously described Connection technology, cf. Detail X in Fig. 6, corresponding Figures 3 and 4, regardless of the geometry the arrangement of the chambers is relative to each other.
