[0002] The traditional copper waveguide is formed by splicing and welding, the welding quality of manual splicing and welding is unstable, the welding equipment is required to be high, the strength of the welding position is not high, the welding seam is easy to be deformed by pulling during assembly, and even cracks, if secondary splicing is carried out, the quality after welding is poor. As important structural parts and transmission carriers, the quality consistency and stability of the waveguide product are extremely crucial. Moreover, the copper waveguide is expensive and heavy in quality, is not conducive to the disassembly and assembly of the electronic equipment which is quickly transferred, and the internal copper waveguide is generally subjected to silver plating treatment based on the requirement of electrical conductivity, the price of the silver plating process is high, and the uniform consistency cannot be guaranteed.
[0003] At present, part of the copper waveguide is replaced by aluminum waveguide, aluminum is lighter, and the commonly used surface treatment of the aluminum waveguide is conductive oxidation treatment, which replaces the expensive silver plating treatment required by the copper waveguide and reduces the cost.
[0004] However, the aluminum material is not suitable for welding, so how to splice the aluminum waveguide is a problem to be solved at present. CONTENT OF THE UTILITY MODEL

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0023] Example 1
[0024] This embodiment of the straight waveguide splicing structure includes a straight waveguide 1 and a flange 2, as follows: Figure 1 As shown, the cross-section of the straight waveguide 1 is rectangular. The left part of the figure is the main view, and the right part is the right view.
[0025] like Figure 2 As shown, flange 2 includes journal 21 and connecting part 22. The upper left part of the figure is the front view, the right side is the right view, and the bottom is the top view. Figure 4As shown, the cross section of journal 212 matches the cross section of straight waveguide 1. Journal 21 is fitted onto the end of straight waveguide 1 and fixedly connected by screws. The connection between journal 21 and straight waveguide 1 is wrapped with composite material 3 to form a straight waveguide splicing structure. Adjacent straight waveguide splicing structures are connected by the connection part 22 of flange 2.
[0026] Example 2
[0027] This embodiment is a further design based on Embodiment 1. Specifically, conductive adhesive is applied to the contact area between the inner wall of the journal 21 and the outer wall of the end of the straight waveguide 1.
[0028] The straight waveguide 1 has screw holes on both sidewalls. The journal 21 has a connecting hole 211 at the corresponding position of the screw hole. The journal 21 is fixedly connected to the end of the straight waveguide 1 by screwing the bolt through the connecting hole.
[0029] In this embodiment, the narrower side of the four sides of the straight waveguide 1 has two screw holes, and the wider side has three screw holes. The corresponding side of the journal 21 also has two connecting holes and three connecting holes. The connecting part 22 has several mating holes for fixing to the connecting part of the adjacent straight waveguide splicing structure by bolts.
[0030] In this embodiment, the straight waveguide 1 is made of aluminum and undergoes conductive oxidation treatment. By using an aluminum waveguide instead of a copper waveguide, aluminum is lighter, and the commonly used conductive oxidation surface treatment replaces the expensive silver plating required for copper waveguides, thus reducing costs. The aluminum waveguide is bonded to the flange with conductive adhesive and fixed with bolts, achieving the goal of integral molding of the waveguide and flange. The end portion of the bonded waveguide is then wrapped with a composite material to strengthen the support strength of the waveguide end and ensure the stability of the stressed portion.
[0031] In this embodiment, during assembly, the straight waveguide 1 is first connected to the journal 21 of the flange 2, with a certain distance maintained between the flange 2 and the port of the straight waveguide 1. Figure 3 The micro-cured conductive adhesive is applied along the outer diameter of the waveguide. Figure 3 In the area outlined in the dashed box, ensure the adhesive is applied evenly across all four waveguide planes. After application, slowly move flange 2 towards the waveguide port, pressing and pushing the conductive adhesive until the flange reaches the waveguide port. Wipe away any excess adhesive, then screw flange 2 onto the port of straight waveguide 1 using bolts. Repeat the above steps in the other direction. After screwing, place the product... Figure 4 Leave it to stand and wait for the conductive adhesive to fully cure.
[0032] Then, using composite material 3, in this embodiment, carbon fiber is used to wrap the end of the connection between the straight waveguide 1 and the journal 21 of the flange, such as... Figure 5As shown, after wrapping with a certain number of layers and in a certain direction, the purpose of strengthening the end force is achieved. After ensuring that there is sufficient support strength here, it can be connected and used with other waveguides. After the composite material is cured and formed, it is locally polished and washed with water.
[0033] Several straight waveguide splicing structures are interconnected by flanges to form a path for the transmission of electrical signals.
[0034] The technical solutions of this utility model are not limited to the above embodiments. All technical solutions obtained by equivalent substitution fall within the scope of protection claimed by this utility model.
