Description
Technical field
The utility model relates to a kind of cavity, and particularly a kind of decimeter wave band pass filter does not have frock welding cavity.
Background technology
The decimever television transmitter generally all needs to use band pass filter, meets national standard to guarantee the transmitter outgoing television signal.In powerful band pass filter adopt coaxial cavity formula filter mostly.For making compact conformation, convenient employing cross-couplings designs, and cavity generally is designed to folding mode.The cavity of six cavity filters as shown in Figure 1 also has four chambeies, eight chambeies or the filter of multi-cavity more.Described cavity mainly is by longitudinal baffle 1, lateral partitions 2, is with vertical side plate 3, horizontal side plate 4 all around, on cover plate 5 is arranged, the rectangular hexahedron that has base plate 6 to be constituted down.Described longitudinal baffle 1 and lateral partitions 2 are right-angled intersection and are provided with described cavity is separated into a plurality of chambers.The roughness in the cavity and the size of the contact resistance between each plate are the keys of decision filter loss size.Roughness depends on the quality of plate surface, and the contact resistance between each plate depends on the design processing method.For saving material, adopt sheet copper to be welded.Because the dimension precision requirement of cavity is very tight, welds what a cavity, difficulty is very big.
Many both at home and abroad at present employing frocks are welded together with each plate, the weld jig complex structure, not only make the increase of cavity manufacturing cost very big, and very not favourable aspect the control distortion, because frock has restricted expanding with heat and contract with cold of workpiece in the process of weld heating, to cause workpiece to have bigger residual stress, in addition, because the frock quality is very big, increased the workpiece time of staying at high temperature, make the material grain growth serious, particularly autoclasis easily takes place in the brass part in follow-up plating processing.
For overcoming the above-mentioned defective that adopts the frock welding to be brought, adopt the assembling of tenon inserting mode in the import cavity, under no machine condition, weld then.Concrete structure is in the both sides of dividing plate and bottom plug tenon to be set, and corresponding mortise is set on side plate, and the plug tenon root is cut sulculus as shown in Figure 2, and the tenon extension is turned round an angle, cavity is shaped, then welding.This mode needs the mould of die-cut sulculus, the mould structure complexity, because this cavity output is limited, it is very expensive that the cavity processed mould is gone at the stand.Protrude in the cavity outside on the other hand, and to reverse plug tenon not only not attractive in appearance, and install and handling process in scratch easily.
Because the above-mentioned defective that above-mentioned existing cavity body structure exists, the design people is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, and cooperate the utilization of scientific principle, and actively studied innovation, make it have more practicality in the hope of what found a kind of new structure.Through constantly research, design, and, create the utility model that has practical value finally through after studying sample and improvement repeatedly.
