Radio frequency adjustment structure

Abstract

An RF conditioning structure includes a base, double-layered covers (upper and lower covers), an adjustable screw, and a chip collection component. The upper cover fits onto the lower cover to form a clamping cavity, and the lower cover fits onto the base to form a functional cavity. The upper cover has a first through hole, and the lower cover has a second through hole. The chip collection component includes an integrally formed flange portion and an annular wall portion. The flange portion is disposed within the clamping cavity and has a first opening, and the annular wall portion is disposed within the functional cavity and has a second opening. The adjustable screw passes through the first through hole, the first opening, the second through hole, and the second opening, and partially extends into the functional cavity. The annular wall portion has an inner wall surface facing the adjustable screw and an outer wall surface with barbs that can abut against the underside of the lower cover. This invention reduces the risk of the chip collection component detaching from the lower cover and falling off.

Claims

1. A radio frequency conditioning structure, wherein, include: Base; A double-layer cover plate is provided with a through hole and includes an upper cover plate and a lower cover plate. The upper cover plate covers the lower cover plate and the lower cover plate covers the base. There is a clamping cavity between the upper cover plate and the lower cover plate and a functional cavity between the lower cover plate and the base. The through hole includes a first through hole provided on the upper cover plate and a second through hole provided on the lower cover plate. An adjustable screw; and a chip collecting component, including an integrally formed flange portion and an annular wall portion. The flange portion is disposed in the clamping cavity and has a first opening at the top of the chip collecting component. The annular wall portion is disposed in the functional cavity and has a second opening at the bottom of the chip collecting component. The first opening communicates with the first through hole and the second through hole, and the second opening communicates with the functional cavity. The adjustable screw sequentially passes through the first through hole, the first opening, the second through hole, and the second opening and partially extends into the functional cavity. The annular wall portion has an inner wall surface and an outer wall surface. The inner wall surface faces the adjustable screw. The outer wall surface has barbs near the flange portion. The barbs extend toward the lower cover plate and can abut against the lower cover plate.

2. The radio frequency conditioning structure as described in claim 1, wherein: The upper cover plate has a first top surface and a first bottom surface, and the lower cover plate has a second top surface and a second bottom surface. The first top surface, the first bottom surface, the second top surface and the second bottom surface are arranged sequentially. The barb has a top plane and a guide slope. The top plane faces the second bottom surface and is in contact with the second bottom surface. The guide slope is located below the top plane and extends obliquely relative to the top plane.

3. The radio frequency conditioning structure as described in claim 2, wherein: One end of the top plane is connected to the outer wall surface and the other end is connected to the guide ramp. One end of the guide ramp is connected to the top plane and the other end is connected to the outer wall surface. The guide ramp and the outer wall surface form an obtuse angle facing outward.

4. The radio frequency conditioning structure as described in claim 2, wherein: The annular wall surrounds the adjustable screw, and the barb surrounds the annular wall.

5. The radio frequency conditioning structure as described in claim 2, wherein: The clamping cavity is formed by the upper cover plate and / or the lower cover plate using one of the methods of clearance and stretching.

6. The radio frequency conditioning structure as described in claim 5, wherein: Both the upper cover plate and the lower cover plate are provided with clearance positions for forming the clamping cavity. The first clearance position of the upper cover plate is formed on the first bottom surface, and the second clearance position of the lower cover plate is formed on the second top surface. The first bottom surface and the second top surface are in contact with each other except for the portion that avoids the clearance position.

7. The radio frequency conditioning structure as described in claim 1, wherein: The adjustable screw includes an upper threaded rod portion and a lower smooth rod portion. The smooth rod portion is integrally formed with the threaded rod portion and their central axes are aligned. The radial dimension of the smooth rod portion is smaller than that of the threaded rod portion. The smooth rod portion abuts against the chip collecting member at the second opening.

8. The radio frequency conditioning structure as described in claim 7, wherein: The inner wall has a middle section that contacts the adjustable screw, and a stepped portion is formed between the middle section and the first opening at the top of the chip collecting member. A first chip receiving groove is formed between the threaded rod portion and the stepped portion.

9. The radio frequency conditioning structure as described in claim 7, wherein: The inner wall has a middle section that contacts the adjustable screw, and a constricted portion is formed between the middle section and the second opening at the bottom of the chip collecting member. A second chip receiving groove is formed between the smooth rod and the constricted portion.

10. The radio frequency conditioning structure as described in claim 1, wherein: The through hole has an internal thread, and the threaded rod above the adjustable screw has an external thread. The adjustable screw is adjustablely positioned and connected to the cover plate by the cooperation between the internal thread and the external thread.

11. The radio frequency conditioning structure as described in claim 1, wherein: It also includes a nut fixed to the cover plate, the adjustable screw passing through the nut and into the through hole, the threaded part of the adjustable screw having an external thread and the nut having an internal thread, the adjustable screw being adjustablely positioned and connected to the cover plate by the cooperation between the internal thread and the external thread.

12. The radio frequency conditioning structure as described in claim 1, wherein: It also includes a resonant rod located within the functional cavity and fixed to the base, with the adjustable screw positioned directly above the resonant rod.
