Abstract
The utility model discloses a connecting structure of a cover plate of a resonant cavity and an outer conductor. The connecting structure comprises the cover plate of the resonant cavity and the outer conductor, wherein the outer conductor is a cylinder, a groove is formed at the upper end of the outer conductor, and a convex edge is arranged on an upper wall of the groove; a through hole is formed in the cover plate of the resonant cavity; the diameter of the through hole is smaller than that of an outer circle of the convex edge and greater than that of an outer wall of the outer conductor; and the through hole in the cover plate of the resonant cavity is riveted with the groove of the outer conductor in an extrusion mode. By adoption of the connecting structure, material consumption of the whole conductor is reduced, and the cost of the materials is reduced; one hole is required to be processed in the cover plate, so that easiness of processing is realized; the outer conductor which is the cylinder is easy to process; and an extrusion riveting structure is firm and reliable, so that the design reliability of a filter is improved overall.
Description
Technical field
The utility model relates to a kind of communications parts, particularly a kind of resonant cavity cover plate and outer conductor syndeton.
Background technology
The mode that the mounting means that the filter industry connects outer conductor and cover plate firmly adopts screw to install mostly; Under the situation that conductor diameter is certain outside; The mode that screw is installed can increase the volume of outer conductor greatly; Increased the material cost of outer conductor, the while is excessive owing to outer conductor on the cover board occupies, and has influenced the screw installation site of resonant cavity cover plate and resonant cavity.And the hard installation region that connects outer conductor also needs processing on the cover plate, has increased processing cost.
Summary of the invention
The purpose of the utility model is in order to overcome the influence of above-mentioned background technology to installation reliability; And the riveted joint design that a kind of outer conductor and cover plate are provided for the material cost that reduces outer conductor; Simple realization easily of its processing and fabricating and cost of manufacture are lower, have satisfied the requirement of filter reliability of products.
For realizing above-mentioned purpose; A kind of resonant cavity cover plate and the outer conductor syndeton of the utility model design; Comprise resonant cavity cover plate and outer conductor, said outer conductor is a column, is provided with a circle chimb at the upper end edge circumferencial direction of column; Cylinder outer surface at the root of chimb is provided with a ring recess; Said resonant cavity cover plate is provided with through hole, and the diameter of this through hole is less than the external diameter of chimb and greater than the diameter of outer conductor, the through hole of said resonant cavity cover plate is riveted through the fashion of extrusion and the groove of outer conductor.
In technique scheme, said resonant cavity cover plate material is softer than the material of outer conductor than the soft said resonant cavity cover plate material of the material of outer conductor, is convenient to realize the above-mentioned fashion of extrusion riveted structure of passing through.
The outer conductor of the utility model and the riveted structure of cover plate; Have following beneficial effect: the outer conductor materials are few, reduced material cost, only need process a hole on the cover plate; Processing is simple; Outer conductor is the column handling ease, and this sound construction that presses is reliable, has improved the reliability of Design of Filter generally.
Description of drawings
Fig. 1 is resonant cavity cover plate (1) structural representation of the utility model;
Fig. 2 is outer conductor (2) structural representation of the utility model;
Fig. 3 is the utility model overall structure sketch map;
Among the figure: 1, resonant cavity cover plate, 1.1, through hole, 2, outer conductor, 2.1, chimb, 2.2, groove, 2.3, the outer wall of outer conductor.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to describe in detail:
The utility model resonant cavity cover plate and outer conductor syndeton; Comprise resonant cavity cover plate 1 and outer conductor 2; Outer conductor 2 is a column, is provided with a circle chimb 2.1 at the upper end edge circumferencial direction of column, is provided with a ring recess 2.2 at the cylinder outer surface of the root of chimb 2.1; Resonant cavity cover plate 1 is provided with through hole 1.1; The diameter of this through hole 1.1 is less than the outside diameter of chimb 2.1, and greater than outer wall 2.3 diameters of outer conductor, the through hole 1.1 of resonant cavity cover plate 1 is riveted through the fashion of extrusion and the groove 2.2 of outer conductor 2.Resonant cavity cover plate 1 material is softer than the material of outer conductor 2.
Hard connection outer conductor is a column; It is bigger slightly than 1.1 sizes of the through hole on the resonant cavity cover plate that the upper wall of groove 2.2 is provided with chimb 2.1; The outer wall 2.3 of outer conductor is slightly littler than through hole 1.1 sizes of resonant cavity cover plate, forms a kind of matched in clearance each other, and the through hole 1.1 in the process of riveted joint on the resonant cavity cover plate 1 overlaps with chimb 2.1 some material of outer conductor; Because resonant cavity cover plate 1 material of selecting for use is softer than the material of outer conductor 2; Under the external force squeezing action, this a part of material can be squeezed in the groove 2.2 on the outer conductor in the groove that the through hole 1.1 with the resonant cavity cover plate forms on the cover plate 1, and last outer conductor 2 has been completely fixed on the resonant cavity cover plate 1; This sound construction that presses is reliable, has improved the reliability of Design of Filter.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from the spirit and the scope of the utility model.Like this, belong within the scope of the utility model claim and equivalent technologies thereof if these of the utility model are revised with modification, then the utility model also is intended to comprise these changes and modification interior.
The content of not doing in this specification to describe in detail belongs to this area professional and technical personnel's known prior art.
