Description

Technical Field

[0001] The present invention belongs to the technical field of filter coupling debugging, and particularly relates to a deformation coupling debugging structure for a filter. Background Art

[0002] With the rapid development of the communication industry, filters tend to be integrated, miniaturized, and have low intermodulation requirements. In the traditional scheme, screw-threading debugging is shown to complete frequency debugging by adjusting the length of the screw entering the resonator in the cavity. In this debugging method, a threaded engagement structure is adopted. Since both the screw and the cover plate are made of conductive metal materials, metal debris generated by the threaded friction between the metals will fall into the closed cavity during the debugging process, which has a great impact on the intermodulation of the filter. After the traditional filter is debugged, the metal debris accumulated in the filter cavity will cause the stability index of the whole filter to deteriorate. Summary of the Invention

[0003] In order to solve the problem that after the traditional filter described in the background art is debugged, metal debris generated by the threaded friction between the metals will fall into the closed cavity, resulting in the deterioration of the stability index of the whole filter, the present invention proposes the following technical solutions:

[0005] Wherein, the sealing seat includes: a housing, a sealing ring, and a diversion tube; one end of the housing is recessed to form an annular limiting groove, the other end of the housing is communicated with the fluid storage through the diversion tube; the sealing ring is embedded in the annular limiting groove, and a pressure sensor is arranged on the diversion tube.

[0006] Further, the thickness of the coupling area is less than the thickness of the cover plate.

[0007] Further, a adjusting column protrudes from the side of the coupling area away from the resonator, the adjusting column is coaxially arranged with the resonator, and a repair blind hole is arranged in the adjusting column.

[0008] Furthermore, the interior of the cover is of a variable diameter structure, and the diameter of the cover near one end of the diversion tube is smaller than the diameter of the cover far from the diversion tube.

[0009] Furthermore, the inner diameter of the cover is less than or equal to the diameter of the coupling region.

[0010] Beneficial effects: By adjusting the amount of fluid output from the fluid reservoir into the closed space, the present invention causes plastic deformation of the coupling region, thereby adjusting the distance between the coupling region and the resonator, and further completing the coupling debugging process of the filter.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0014] Figure 1 FIG. is a schematic structural diagram of a deformation coupling debugging structure for a filter according to an embodiment of the present invention.

[0015] Refer to Figure 1 , a deformation coupling debugging structure of a sealing seat 2 according to an embodiment of the present invention includes: a cover plate 1, a sealing seat 2, a base 3, and a fluid reservoir 4. Among them, the cover plate 1 is detachably arranged at the end of the base 3 through a connecting member 5 to close the entire resonant cavity. A coupling region 11 for adjusting the coupling degree of the entire filter is provided on the surface of the cover plate 1, and the sealing seat 2 is vertically arranged on the outer periphery of the coupling region 11. One side of the sealing seat 2 abuts against the surface of the cover plate 1 to form a closed hole space, and the other side of the sealing seat 2 is communicated with the fluid reservoir 4. A resonator 31 is arranged in the base 3, and the resonator 31, the base 3, and the sealing seat 2 are coaxially arranged.

[0016] During the coupling debugging process, the operator fills the enclosed space with fluid through the fluid reservoir 4, causing plastic deformation in the coupling region 11, thereby changing the distance between the coupling region 11 and the resonator 31, and then completing the coupling debugging process. In addition, during the coupling debugging process, the operator can quickly complete the coupling debugging process during production by setting the total amount of fluid filled into the enclosed space. After the coupling debugging is completed, the operator only needs to detach the sealing seat 2 from the surface of the cover plate 1 to enter the next process.

[0017] Specifically, the sealing seat 2 includes: a cover body 21, a sealing ring 22, and a diversion pipe 23. An annular groove 211 is formed by the depression at the end of the cover body 21, and the sealing ring 22 is embedded in the annular groove 211. The diversion pipe 23 is a flexible pipe. One end of the diversion pipe 23 is connected to the inside of the cover body 21, and the other end of the diversion pipe 23 is connected to the fluid reservoir 4. A pressure sensor 231 is provided on the diversion pipe 23. During the debugging process, the operator controls the output of the fluid from the fluid reservoir 4 according to the value of the pressure sensor 231. The surface of the cover body 21 abuts against the cover plate 1, and the extending direction of the cover body 21 is perpendicular to the plane direction of the cover plate 1. The cover body 21 is arranged on the outer periphery of the coupling region 11, thereby forming an enclosed space with the coupling region 11 as the bottom. Preferably, in order to further enhance the sealing performance of the enclosed space, in this embodiment, the inner diameter of the cover body 21 is equal to the diameter of the coupling region 11. In other embodiments, the diameter of the coupling region 11 is greater than the inner diameter of the cover body 21. Among them, the diameter size of the coupling region 11 is related to the tuning amount of the overall filter. The larger the coupling region 11, the larger the coupling area and the larger the frequency tuning range. The distance between the coupling region 11 and the resonator 31 is related to the resonant frequency of the filter. When the distance between the coupling region 11 and the resonator 31 decreases, the frequency decreases.

[0018] Furthermore, the interior of the cover body 21 has a variable diameter structure. The diameter of the cover body 21 on the side away from the diversion pipe 23 is smaller than the diameter of the cover body 21 on the side close to the diversion pipe 23. During the coupling debugging process, when the fluid in the fluid reservoir 4 flows through the diversion pipe 23 into the enclosed space, the flow rate of the fluid slows down, thus avoiding a situation where a large amount of fluid quickly flows into the enclosed space, resulting in too short a reaction time for coupling debugging and thus over-coupling. Among them, the fluid stored in the fluid reservoir 4 is liquid or gas, such as commonly used compressed air and lubricating oil, etc. In this embodiment, the fluid stored in the fluid reservoir 4 is compressed air.

[0019] Specifically, on the end face of the cover body 21, the thickness of the coupling region 11 is less than the thickness of the cover plate 1. In addition, in order to further enable the remedy of the coupling excess error during the debugging process, in this embodiment, an adjustment post 6 is formed by protruding in the coupling region 11. A repair blind hole 61 is provided in the adjustment post 6. When the coupling is excessive, an operator can insert a connecting member 5 into the repair blind hole 61, and the operator can lift the distance between the coupling region 11 and the resonator 31 by pulling up the connecting member 5, thereby repairing the cover plate 1 with excessive coupling. After the repair is completed, the corresponding connecting member 5 needs to be taken out from the repair blind hole 61 to ensure the normal production of the product.

[0020] In summary, the present invention adjusts the plastic deformation of the coupling region by adjusting the amount of fluid output from the fluid reservoir into the closed space, thereby adjusting the distance between the coupling region and the resonator, and further completing the coupling debugging process of the filter.
