Definitions
- the invention relates to a waveguide fitting for connecting of two waveguides, in particular for connecting one Rectangular waveguide with an elliptical waveguide.
- the invention has for its object a waveguide fitting to create that with simple means and little effort with a waveguide that is a non-rectangular and in particular an elliptical cross section has connected, while ensuring that the connection made is very poor in reflection and intermodulation is.
- the Armature conductive at least at one end with the first Section of a sleeve is connected, the second section to accommodate the end area of the to be connected Waveguide is determined and at least in this second Section through narrow, capillary acting, axial Which is divided into radially resilient slats after inserting the waveguide at least in some areas rest against its outer wall, and that the inner wall at least the second section of the sleeve Recording at least one solder deposit is formed.
- the waveguide Before or after attaching the solder deposit, the waveguide needs with which the connection is to be established, only still cut to the correct length and in the second Section of the sleeve pushed in as far as it will go become. Then the junction becomes so far warmed until proper soldering occurs. This can be checked from the outside because the slots in the Sleeve are kept so narrow that the solder has become liquid it fills up due to the capillary effect. Therefore, the Connection also at the installation site itself and from only little trained Personnel, e.g. Personnel of the operator of the concerned System, reliably manufactured and on their quality be checked.
- this waveguide fitting has its other End a usual flange for connection to the flange a standard waveguide, e.g. a rectangular waveguide.
- the waveguide fitting can be a mirror image trained, so with a second, accordingly designed sleeve.
- the valve according to the invention is basically suitable for connecting two Any waveguide, except rectangular cross-section or to connect e.g. a rectangular waveguide with a smooth-walled waveguide or a waveguide with corrugated walls and circular or elliptical Cross-section.
- the solder depot can be a solder molded part inserted into the sleeve be (claim 2).
- the solder molding can in particular as Ring, designed as a film or as a sleeve and if necessary also be designed in the form of two half-shells.
- the waveguide fitting according to the present invention is preferably used Proposal to connect to a screw-corrugated, so-called elliptical waveguide. Then it was useful the second, to accommodate this elliptical waveguide certain section of the sleeve one to the screw corrugation of the waveguide approximately complementary inner profile (claim 3).
- the solder depot can be made of flux-containing solder wire, on the best flux wire soldered, in a helical Groove in the inner wall of the second section of the Insist sleeve (claim 4).
- the helical groove can be in the valley of the Screw corrugation of the waveguide complementary inner profile of the second section of the sleeve (claim 5).
- the sleeve can be between its first and its second Section an ellipse-like lying in a radial plane Ring surface have that of an end face of the valve is spaced apart by a capillary gap, wherein between the elliptical ring surface and the front surface of the Fitting a second solder deposit is formed (claim 7).
- This second solder deposit ensures that between the Armature and the connected waveguide after soldering A safe front edge contact over the entire circumference exists that at the same time the connection point after outside is RF-tight, and that the connected waveguide Mechanically intercepted reliably via the sleeve, i.e. firmly is connected to the valve.
- This second solder deposit also preferably consists of flux-containing material Solder wire in a groove in the ellipse-like Annular surface of the sleeve (claim 8).
- the arm end of the sleeve is preferably more solid Formed ring and firmly connected to the valve, being between the inner peripheral surface of this ring and the outer circumferential surface area that it engages the valve is arranged at least one further solder depot is (claim 9).
- This further (or third) solder deposit causes that the sleeve practically in one piece after soldering with the valve. This means that this additional plumbing depot also performs contribute to the firm connection between the Armature and the connected waveguide.
- a capillary gap can exist between the further solder depot the roots of the lamellas of the sleeve and the outer Connect peripheral surface of the valve (claim 10).
- the liquid solder not only fills the capillary gap completely and creates a broad Ring over which the sleeve is soldered to the fitting also fills the slits under the capillary action the roots of the lamellae of the sleeve, which at the same time also in this area a visual control of the Allows goodness of soldering from the outside.
- the further solder depot can in turn be made of flux Solder wire exist in a circumferential groove in the inner Circumferential surface of the ring of the sleeve or the outer peripheral surface the valve in its covered by the sleeve Area can be provided (claim 11).
- Figure 1 shows a fitting 50, which is at its upper end a cross-section (e.g. circular or elliptical) of a waveguide 60 has a corresponding recess.
- the recess is the end section of the waveguide 60 added, which is helically corrugated.
- a correspondingly this corrugated profiled solder part 70 surrounds it End of the waveguide 60 on one of the depth of the recess in the fitting 50 corresponding length.
- the solder molding 70 can be made from a suitably profiled and wound Band made of solder material or from corresponding, preformed composite half shells exist. After this Inserting the waveguide 60 including the solder molded part 70 in the recess of the fitting 50 is the connection area warmed until the solder melts.
- the solder can only be in the narrow edge zone 51 can be observed at the end of the armature 50. Not from the outside it can be checked whether the solder is also in the area of the front edge 61 of the waveguide 60 is completely melted and has created a secure solder joint or vice versa an excess of solder around this front edge 61 in the interior of the fitting 50 has flowed, which is the reflection factor increase significantly at this junction could. Therefore, this embodiment is not suitable for high quality connections.
- FIGS. 2 to 5 show a better solution, namely that according to the invention.
- a waveguide fitting 1 is at its lower end a flange 11 with holes 12 for screwing a not shown, e.g. usual rectangular waveguide provided, and with its upper end with a so-called elliptical waveguide 3 connected.
- the fitting 1 carries a sleeve 2 which with part of its length the upper Reaches over the end area of the fitting 1. With the other part its length overlaps the sleeve 2 about three helical Corrugations (see Fig. 3) of the elliptical waveguide 3, whose cross section is only elliptical is, as Figure 4 illustrates.
- Such waveguides are in Known in the art, e.g. under the name FLEX-WELL from RFS in Hanover, Germany.
- the fitting 1 also acts as Transformer, the different types of shafts that on the one hand in the rectangular waveguide, not shown, on the other hand, propagate in the elliptical waveguide 3, merged.
- the valve starting from its upper end face 13, over a defined Lengthening its rectangular inner cross-section, opposing, bowl-shaped recesses 14, 15 (see FIG. 4).
- the frequency, cross-section and The geometry of such fittings depending on the type of shaft is Known in the art and therefore not the subject of the invention.
- the sleeve 2 consists of a metallic, easily solderable and resilient material and can be silver-plated.
- the sleeve 2 comprises a solid ring 21 with which the Sleeve e.g. in a press fit against a ring shoulder 16 the fitting 1 rests and encloses it on the outside.
- On the remaining part of its length is the sleeve 2 by numerous, narrow slots 22 divided into an equally large number of slats 23, who have their roots on the ring 21.
- the inner dimension of the sleeve 2 is in the area of the waveguide 3 receiving section designed so that the slats 23 after inserting the waveguide 3 against it Shaft apex 31 resiliently resilient.
- the inner contour 24 of the sleeve 2 follows the approximately helical profile the corrugation of the waveguide 3 without therefore to this Curl to be exactly complementary. The only important thing is that the approximately helical valley 25 of the inner profile of the Sleeve 2 of the approximately helical apex line Screw corrugation of the waveguide 3 follows.
- the inner contour 24 of the sleeve 2 by a small Amount in the axial direction compared to the helical Profile of the waveguide 3 offset so that after insertion of the waveguide 2 an axial force component arises on the waveguide 3 in the direction of the end face 13 of the armature 1 acts.
- This is one hand ensures that the waveguide in the inner contour 24th the sleeve 2 engages and that the end edge 32 of the waveguide 3 bears against the end face 13 of the fitting 1.
- this measure creates a slight restraint of the waveguide 3 in the recess of the sleeve 2 generates a separate fixation of the valve 1 opposite the waveguide 3 during the later soldering process can spare.
- the section of the sleeve 2 receiving the waveguide 3 ends at an ellipse-like annular surface 27, which of the End face 13 of the fitting 1 spaced apart by a capillary gap a is.
- Located in the elliptical ring surface 27 in one of the end edges 32 of the waveguide 3 groove 28 is approximately equally spaced over its circumference another flux-spiked solder wire 42 and forms one second solder depot.
- the groove 28 could also be in the end face 13 of the sleeve 2 are. Between the groove 28 and the groove 26 may not be connected. With small ones Waveguide cross sections can dispense with the groove 28 become. The groove 26 then begins in the plane of the end face 13th
- the fitting 1 has a groove 17 on the outside at the level of the ring 21 of the sleeve 2.
- This groove 17 could alternatively be located in the inner surface of the ring 21. It contains a flux-spiked solder wire 43 as the third solder deposit.
- a capillary gap b adjoins the groove between the roots of the fins 23 of the sleeve 2 and the outer peripheral surface of the fitting 1 in this area.
- Figure 5 shows the state after soldering. Lot's areas that are covered or filled with dots are dotted hinted as far as they are recognizable in the figure are.
- Figure 6 shows an embodiment that is particular suitable for waveguides with large cross-sectional dimensions.
- the inner contour 24 of the sleeve 2 approximately helical Profile of the undulation of the waveguide 3. It is different that the helical groove 26 'into which the solder wire 41 is inserted, not in the valley (25 in Fig. 3) of the inner contour 24 but is offset by half a pitch, so that they the helical wave trough 33 of the waveguide 3 follows.
