Description

Technical Field

[0001] This utility model relates to the field of resonators, and in particular to a highly stable microwave dielectric resonator. Background Technology

[0002] A resonator is an electronic component or physical device that achieves frequency-selective response based on the principle of resonance. Its core function is that when the frequency of the input signal matches its natural frequency, the system generates significant amplitude amplification through the resonance effect, while effectively suppressing signals in other frequency bands, thereby achieving precise frequency selection and signal enhancement.

[0003] In practical applications, resonators are typically fixed to the circuit board via lead soldering. Due to their resonant operating characteristics, the device generates periodic mechanical vibrations during continuous operation. Furthermore, the resonator's outer casing has a large mass, and this vibration causes the casing to vibrate, which in turn affects the lead positions. Prolonged vibration leads to stress accumulation between the leads and solder joints, causing fretting wear at the solder interface and consequently degrading contact reliability. This process may gradually evolve into poor solder joints, eventually causing the device to detach from its intended mounting position and resulting in circuit malfunction. Utility Model Content

[0004] The technical problem to be solved by this invention is to overcome the defects of the existing technology. This invention proposes a highly stable microwave dielectric resonator.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A highly stable microwave dielectric resonator includes: a resonator body, with a first ring sleeved on the outside of the resonator body; a plurality of extension blocks are mounted on the first ring, with at least two extension blocks; screws are mounted on the extension blocks through screw holes; rubber blocks are mounted on the bottom of the screws; after the resonator body is installed, the screws are rotated, and the screws move along the extension blocks, causing the rubber blocks to contact the upper surface of the mounting position. This operation is repeated until all the rubber blocks at the bottom of the screws contact the upper surface of the mounting point. The screws provide auxiliary support for the resonator body, and the deformation of the rubber blocks buffers the external vibration of the resonator body.

[0006] Preferably, a rotating block for rotating the screw is installed on the top of the screw. The outer surface of the rotating block is rough to increase the friction on the outer side of the rotating block. The outer diameter of the rotating block is larger than the outer diameter of the screw.

[0007] Preferably, the rubber block consists of a bottom block and a top cylinder. The cylinder increases the contact area between the rubber block and the screw, thereby improving the fixing stability between the rubber block and the screw.

[0008] Preferably, a fixing mechanism for fixing the first ring to the outside of the resonator body is installed on the inner side of the first ring.

[0009] Preferably, the fixing mechanism includes a second ring installed inside the first ring; a gap is provided between the outer side of the second ring and the inner side of the first ring, and the number of gaps is at least one; a pressing block for pressing the second ring is movably inserted in the gap; a third ring for driving the pressing block to move is installed on the top of the pressing block.

[0010] Preferably, the second ring is made of rubber, and the inner diameter of the second ring is larger than the outer diameter of the resonator body.

[0011] Preferably, the extrusion block has a trapezoidal cross-section, with the inclined surface of the trapezoid closely attached to the second ring. The bottom of the extrusion block is a small end, and the top is a large end. The small end of the extrusion block is inserted into the gap, and the extrusion block is moved downward through the third ring, allowing the extrusion block to move inside the gap. As the volume of the extrusion block increases inside the gap, it compresses the second ring until the deformed second ring compresses the outside of the resonator body. The frictional force then fixes the first ring to the resonator body.

[0012] Preferably, the inner diameter of the second ring is larger than the outer diameter of the resonator body, so that the second ring can be fitted over the resonator body from either top or bottom.

[0013] Compared with the prior art, the beneficial effects of this utility model include: 1. The resonator body is supported by a screw to reduce the impact of vibration on the resonator body pins. At the same time, the bottom rubber ring and the second rubber ring provide buffering, further reducing the impact of rotation on the resonator body pins and ensuring the stability of the resonator body during use.

[0014] 2. There are at least two screws, which are independently adjustable. This way, no matter how the height of the first ring changes or how the distance between the bottom of the screw and the surface where the installation point is located changes, the screw can be rotated to adjust until the rubber block contacts the surface where the installation point is located.

[0015] 3. The first ring is squeezed by the extrusion block to compress the second ring. The friction between the second ring and the outside of the resonator body is fixed, so the first ring and the resonator body are separable. It can be selected whether to install it as needed, which improves the flexibility of the device. Attached Figure Description

[0017] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0018] According to one embodiment of the present invention, in conjunction with Figures 1-3 As shown.

[0019] A highly stable microwave dielectric resonator has the following structural composition: The resonator comprises a resonator body 1, with a first ring 2 made of stainless steel fitted around the body 1. Several extension blocks 3 are evenly welded to the outside of the first ring 2; at least two extension blocks 3 are provided to ensure structural stability. Each extension block 3 has a screw hole 10 at its center, through which a screw rod 4 is installed. A rotating block 7 is welded to the top of the screw rod 4. This rotating block 7 is specifically designed for rotating the screw rod 4, and its outer surface is roughened to increase external friction for easier operation. Simultaneously, the outer diameter of the rotating block 7 is larger than that of the screw rod 4 for easier gripping. A rubber block 5 is bonded to the bottom of the screw rod 4. This rubber block 5 is integrally formed from a block-shaped bottom portion and a cylindrical top portion. The cylindrical design effectively increases the contact area between the rubber block 5 and the screw rod 4, thereby improving the stability of the fixation.

[0020] Once the resonator body 1 is in place, rotate the screw 4 to move it along the extension block 3 until the rubber block 5 is in close contact with the upper surface of the mounting position. Repeat this operation to ensure that the rubber blocks 5 at the bottom of all screws 4 are in contact with the upper surface of the mounting point. This provides auxiliary support for the resonator body 1 using the screws 4 and effectively buffers the external vibrations experienced by the resonator body 1 by utilizing the deformation characteristics of the rubber blocks 5.

[0021] Furthermore, in this embodiment, a fixing mechanism is added to the inner side of the first ring 2 to securely fix the first ring 2 to the outer side of the resonator body 1. This fixing mechanism includes a second ring 6 bonded to the inner side of the first ring 2. This second ring 6 is made of rubber, and its inner diameter is slightly larger than the outer diameter of the resonator body 1, facilitating the fitting of the second ring 6 onto the resonator body 1. A gap is left between the outer side of the second ring 6 and the inner side of the first ring 2, and at least one gap is provided. Within the gap, compression blocks 8 are movably inserted. These compression blocks 8 have a trapezoidal cross-section, with the inclined surface of the trapezoid in close contact with the second ring 6, and the bottom of the compression block 8 is a small end, while the top is a large end. A third ring 9 is welded to the top of the compression block 8 for driving the compression block 8 to move. During installation, the second ring 6 can be fitted onto the outside of the resonator body 1 from above or below, and then the small end of the compression block 8 is inserted into the gap, and the compression block 8 is moved downwards by the third ring 9. As the extrusion block 8 moves within the gap, its volume gradually increases, thereby extruding and deforming the second ring 6 until the deformed second ring 6 tightly presses against the outer side of the resonator body 1, and the first ring 2 is firmly fixed to the resonator body 1 by friction.

[0022] Working principle: The resonator body 1 is fixed to the target position by soldering the pins. Before the resonator body 1 is fixed, the second ring 6 can be put on the outside of the resonator body 1 from the top or the bottom. Then, the small end of the extrusion block 8 is inserted into the gap, and the extrusion block 8 is moved downward by the third ring 9, so that the extrusion block 8 moves inside the gap. As the volume of the extrusion block 8 inside the gap increases, it extrudes the second ring 6 until the deformed second ring 6 extrudes the outside of the resonator body 1. The first ring 2 is fixed to the resonator body 1 by friction. After the first ring 2 is fixed, the resonator body 1 is fixed. Then, the screw 4 is rotated by the rotating block 7, so that the screw 4 moves along the extension block 3 towards the mounting point through the screw hole 10 until the rubber block 5 contacts the surface of the mounting point. The screw 4 and the rubber block 5 assist in supporting the resonator body 1, reducing the impact of vibration, and the deformation of the rubber block 5 buffers the vibration. Furthermore, the second ring 6 is located between the first ring 2 and the resonator body 1, and the second ring 6 is made of rubber. After being fixed, the second ring 6 can also buffer vibration.

[0023] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
