Definitions
- the invention relates to an elbow for Waveguide connections in the preamble of claim 1 specified type.
- Contra-angles and elbows for waveguide connections serve to change the direction of the energy flow in the waveguide as free of reflections as possible. While this takes place continuously in elbows, the change of direction in elbows is carried out abruptly.
- the bending or kinking can take place in the E plane as well as in the H plane. In the case of contra-angle handpieces, lower reflection factors are obtained at a 45 ° position or by multiple kinking.
- elbows of the type mentioned are in one piece and have a closed design. Thereby conditionally they are manufactured as investment castings. Investment casting is however very much due to its one-off manufacturing process expensive.
- the invention has for its object an elbow for waveguide connections of the type mentioned constructively so that its manufacture by more cost-effective procedure becomes possible.
- the task is for an elbow Waveguide connections in the preamble of claim 1 defined genus according to the invention by the features in Characteristic part of claim 1 solved.
- the contra-angle handpiece according to the invention is characterized by a one-sided open construction from what the manufacture in one Casting process with reusable molds, e.g. B. Die casting process allowed.
- the open form the workpiece is replaced by the one used Waveguide tube completed, so that again closed elbow is created.
- the second advanced waveguide tube is then attached to it trained end flange on the flange surface of the Elbow placed so that it is the connection opening coaxially encloses, the inner contour of the Waveguide tube is flush with the connection opening.
- the Manufacturing costs for the contra-angle can be z. B. at Transition from investment casting to die casting up to reduce to 10%.
- the waveguide tube in the insertion groove of the cap are the clear dimensions of the coaxial to the connection opening Insert groove to double the wall thickness of the insert Waveguide tube chosen larger than the corresponding clear dimensions of the connection opening. This is ensures that the inner contour of the waveguide tube is flush with the connection opening and none reflective edges are present inside the waveguide.
- the waveguide tube inserted in the insertion groove is included the cap is electrically and mechanically firmly connected, what with a metal conductive adhesive or by soldering with a conductive solder can be accomplished.
- Angle piece 10 for a 90 ° deflection in the H plane has in a known manner two connection openings 11, 12 for each a continuative, rectangular one Waveguide tube 13, 14 (FIG. 2) and a deflection surface 15 for the low reflection reflection of the energy flow from Waveguide tube 13 to the waveguide tube 14 or vice versa.
- the connection openings 11, 12 are arranged relative to one another that their normals are perpendicular to each other.
- the Deflection surface 15 is symmetrical to the connection openings 11, 12 aligned, the normals of which an angle of 45 ° to the normals of the connection openings 11, 12 includes.
- the angle piece 10 has a flange 16 with a Flange surface 161 for laying one with the continuing waveguide tube 14 firmly connected End flange 20 (Fig. 2) and one piece on Flange 16 molded cap 17.
- a flange surface 161 In the flange surface 161 is the connection opening 11 and in the cap 17 Connection opening 12 and the deflection surface 15 are formed.
- the cap 17 In the cap 17 there is an opening towards the flange surface 161 U-shaped insertion groove 18 molded into the Connection opening 12 is immediately upstream.
- the for Connection opening 12 coaxial insertion groove 18 is used positive reception of an end section of the continuing waveguide tube 13 and is dimensioned such that when the waveguide tube 13 is inserted, the inner contour of the Waveguide tube 13 flush with the connection opening 12 and the outer contour of the insertion groove 18 terminating Tube wall 131 of the further waveguide tube 13 is flush with flange surface 161. To realize this the clear dimensions of the insertion groove 18 selected so that they double the wall thickness of the continuing Waveguide tube 13 are larger than the corresponding ones clear dimensions of the connection opening 12.
- the angle piece 10 described has by the described constructive design a design open on one side, so that it is easily made in a mold and without Destroying the casting tool can be demolded.
- a Mold can thus a variety of elbows, e.g. B. in the die casting process, rationally manufactured, so that the manufacturing costs compared to a production in Investment casting processes can be extremely reduced.
- a waveguide connection (Fig. 2) the further waveguide tube 13 with his End section in the insertion groove 18 in the angle piece 10 used so that it is with its end face on the Connects opening 12 surrounding shoulder (19). Then the waveguide tube 13 in the insertion groove 18 mechanically set, while at the same time on an electrically conductive Connection is respected.
- This setting can for example by an electrically conductive Metal glue is made on the adjacent one Surfaces of insertion groove 18 and waveguide tube 13 in front Inserting the waveguide tube 13 is applied.
- the Waveguide tube 13 can also be electrically conductive solder are soldered into the insertion groove 18. Thereafter, as shown in Fig.
- Fig. 3 is an angle piece 10 'for one Waveguide connection with a 90 ° deflection in the E plane shown.
- this contra-angle 10 coincides the angle piece 10 in Fig. 1, so that the same Provide construction elements with the same reference numerals are.
- the invention is not based on those described above Embodiments limited. So instead of the a deflecting surface 15 also several deflecting surfaces are provided be in turn symmetrical to the connection openings 11, 12 can be arranged. With an arrangement of three consecutive deflection surfaces are the kink angles of the individual deflection surfaces to each other 26.3 °, 37.4 ° and 26.3 °.
