The casing includes a rectangular bottom plate; four edges of the bottom plate are provided with a front panel, a rear panel, a left side plate and a right side plate respectively which are perpendicular to the rectangular bottom plate; the bottom plate, the front panel, the rear panel, the left side plate and the right side plate form one hollow cavity; a cover plate for sealing the hollow cavity is arranged on the hollow cavity; the inner side of the front panel is provided with a first blocking plate and a second blocking plate which are perpendicular to the front panel and extend into the hollow cavity; the middle of the rear panel is provided with a third blocking plate which is perpendicular to the rear panel and extends into the hollow cavity; and all the above components are connected and fixed by fasteners. The assembling-type filter hollow casing of the utility model is designed based on a plate assembling structure; the machining cost of the whole hollow cavity is under 350 RMB; machining time does not exceed 4 hours; cost can be reduced to 30% of the cost of the machining of a numerical control milling machine; and machining efficiency is also improved by 70%.
Description
Technical field
The utility model relates to a kind of filter assembly, especially a kind of casing of filter.
Background technology
Filter is a kind of universal electric element, the following filter hollow housing of 200MHz frequency adopts the monoblock solid material to process with CNC milling machine mostly at present, raising according to 1/4 Wavelength matched and technical requirement, more than the height of the filter hollow housing that the 200MHz frequency is following generally is greater than 100mm, because element height is too high, and it is lower by the efficiency of general CNC milling machine processing, machining accuracy is difficult to control, whole device fabrication high cost, and machining accuracy can't effectively be controlled, cause properties of product to reduce, product cost is too high, can't accomplish economical and practical.
A 150MHz filter of take is reference, obtaining the hollow cavity diameter according to Insertion Loss and attenuation outside a channel is 65*65*140 (the wide * of long * is high), the hollow cavity joint number is 8 joints, can draw the cumulative volume of hollow cavity, on existing traditional processing mode, if process a set of this type of hollow cavity, machining period generally need to reach more than 15 hours.
Summary of the invention
The utility model provides a kind of working (machining) efficiency high, machining accuracy split mounting type casing of filter.
To achieve these goals, the utility model adopts following technical scheme:
It comprises a rectangular base plate, the four edges edge place of described base plate is provided with respectively the front panel perpendicular to rectangular base plate, rear board, left plate and right plate, described base plate, front panel, rear board, left plate and right plate form a hollow cavity, described hollow cavity is provided with the cover plate of this hollow cavity of sealing, described front panel inboard is provided with perpendicular to front panel and to the first closure plate and the second closure plate that extend in hollow cavity, described rear board middle part is provided with perpendicular to rear board and to the 3rd closure plate extended in hollow cavity, above each parts are connected and fixed by securing member.
Preferably, described the first closure plate and the second closure plate be take the 3rd closure plate and are symmetrical arranged as axis.
Preferably, the distance of described the first closure plate and left plate equals the distance of the first closure plate and the 3rd closure plate.
Preferably, the distance of described the second closure plate and right plate equals the distance of the second closure plate and the 3rd closure plate.
Owing to having adopted said structure, according to the jigsaw package assembly, design draws split mounting type casing of filter of the present utility model, and a whole set of hollow cavity processing cost is in 350 yuan, and process time, every cover was no more than 4 hours; And process with CNC milling machine, a whole set of hollow cavity processing cost surpasses more than 1200 yuan, and process time is longer; According to the jigsaw assembling design, draw, it is CNC milling machine processing 30% that cost can drop to, and working (machining) efficiency has also improved 70%.
