Description

A kind of board-like electric bridge waveguide

Technical field

The utility model relates to a kind of waveguide, particularly relates to a kind of board-like electric bridge waveguide.

Background technology

Waveguide is used for transmitting uhf electromagnetic wave, loss that can be minimum by its pulse signal be sent to destination, the size of waveguide internal diameter because of the wavelength of defeated signal different.Be widely used in the radio fields such as a centimetre radio communication that involves millimeter wave, radar navigation just because of waveguide loss when the transmission electromagnetic wave is little.

The sectional dimension precision of waveguide, inner surface smoothness and geometric accuracy have significant impact to its serviceability.The electric bridge waveguide that now microwave device manufacturing firm continues to use normally processes by the following method: the cavity that is moulding by the drawing segmentation combination by waveguide, then adopt traditional flame brazing method to be welded on molding cavity the parts such as reactance diaphragm, ring flange.There is following drawback in the waveguide of producing like this: 1., when the welding flange of molding cavity two ends, both need be carried out to accurate orientation assemble, and operating personnel often are difficult to accomplish accurate location, waveguide combination precision is not high; 2. because the part that needs the soldering assembling is more, need repeatedly gas brazing, and repeatedly use the stronger fluorine-containing brazing flux of corrosivity during soldering, in cavity, residual brazing flux is difficult to thoroughly remove clean, will be subject to corrosion in various degree in waveguide use procedure afterwards, greatly shorten useful life; 3. repeatedly soldering easily causes the cavity welding deflection large, and the size of components precision such as reactance diaphragm, ring flange are difficult to guarantee.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of energy is self-align, assembly precision is high, antiseptic property is good, the board-like electric bridge waveguide of Functionality, quality and appealing design, long service life.

The purpose of this utility model is achieved through the following technical solutions: a kind of board-like electric bridge waveguide, it comprises upper head plate, bottom plate, left wallboard, right wallboard and dividing plate, upper head plate and bottom plate are provided with ring flange and reactance diaphragm, be equipped with ring flange and dividing plate technology groove on left wallboard and right wallboard, the reactance diaphragm lays respectively at the lower surface of upper head plate and the upper surface of bottom plate, ring flange lays respectively at upper head plate, bottom plate, the two ends of left wallboard and right wallboard, the dividing plate technology groove is positioned at the centre position of left wallboard and right wallboard, the dividing plate both sides are fixed in the dividing plate technology groove of left wallboard and right wallboard, upper head plate and left wallboard, right wallboard is fixed by soldering, bottom plate and left wallboard, right wallboard is fixed by soldering.

Further, on described upper head plate and bottom plate, be equipped with groove, on left wallboard and right wallboard, be equipped with convex shoulder, ring flange is provided with connecting hole.

The beneficial effects of the utility model are:

(1) ring flange is separately positioned on upper and lower end plate and left and right wallboard, without the assembling of carrying out ring flange, not only improved the production efficiency of product, and produce the phenomenon in gap in the time of effectively avoiding ring flange and upper and lower end plate and the combination of left and right wallboard, make electric bridge waveguide die cavity combination precision high;

(2) upper and lower end plate, dividing plate and left and right wallboard all adopt aluminium alloy to process, and antiseptic power is strong;

(3) be respectively equipped with groove and convex shoulder on upper and lower end plate and left and right wallboard, effectively guaranteed the self-align assembling of upper and lower end plate and left and right wallboard, the combination precision is high;

(4) upper and lower end plate, dividing plate and left and right wallboard only need just can be shaped by a vacuum brazing, reduced manufacturing procedure, and welding deformation amount are little.
