Description

Technical Field

[0001] This utility model belongs to the field of coaxial connectors, specifically relating to a coaxial connector vibration damping device and its crystal oscillator. Background Technology

[0002] Because crystal oscillators exhibit acceleration effects, their output performance deteriorates in vibrating environments, severely impacting the performance of electronic devices. Furthermore, vibration can alter the internal dimensions, shape, and stress of coaxial connectors, thus degrading signal transmission. Therefore, vibration damping is necessary for coaxial connectors. However, current damping devices typically consist of a simple planar buffer pad between the coaxial connector and the mounting bracket. This pad's damping effect is limited, and over time, it hardens, further reducing its effectiveness. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a coaxial connector vibration damping device and its crystal oscillator that are simple in structure, have good vibration damping effect, and are easy and quick to install.

[0004] This utility model provides a coaxial connector vibration damping device, including a mounting plate and a plurality of fixed vibration damping mechanisms. The plurality of fixed vibration damping mechanisms are arranged in a ring array on the mounting plate, or the plurality of fixed vibration damping mechanisms are arranged symmetrically on the mounting plate.

[0005] The mounting plate is used to fix the coaxial connector, and the mounting plate is also provided with mounting holes for mounting the fixed vibration damping mechanism;

[0006] The fixed vibration damping mechanism includes a mounting rod, washer I, washer II, and fasteners;

[0007] The fixed end of the mounting rod is fixed to the position to be installed, and the free end to the fixed end of the mounting rod is provided with a fastener mating structure, a limiting boss I and a limiting boss II in sequence;

[0008] The mounting hole is sleeved on the mounting rod between the limiting boss I and the limiting boss II, and the washer I is disposed between the mounting plate and the limiting boss I, and the washer II is disposed between the mounting plate and the limiting boss II;

[0009] The fastener is detachably mounted on the fastener mating structure to prevent the washer I from detaching from the limiting boss I.

[0010] Furthermore, the size of the mounting hole is larger than the size of the mounting rod;

[0011] The washer I or washer II is provided with a buffer ring protruding from it for embedding into the gap between the mounting hole and the mounting rod, and the outer wall of the buffer ring is adapted to the wall of the mounting hole.

[0012] Furthermore, the fastener mating structure is an external thread, and the fastener is a nut I;

[0013] The size of nut I is larger than the size of limiting boss I.

[0014] Furthermore, the fixed end of the mounting rod is detachably coupled to the position to be installed.

[0015] Furthermore, a fixing hole is provided at the installation position, and a screw is provided at the end of the installation rod away from the limiting boss II;

[0016] The screw is threadedly connected to the fixing hole, or the screw passes through the fixing hole and is screwed with a nut II.

[0017] Furthermore, the limiting boss II abuts against the surface of the position to be installed.

[0018] Furthermore, the mounting plate has a through hole in the middle for inserting a coaxial connector;

[0019] The coaxial connector has a flange on one side of the through hole, and the flange is detachably connected to the mounting plate.

[0020] Furthermore, the flange is connected to the mounting plate by bolt fasteners.

[0021] This utility model also provides a crystal oscillator, including a mounting bracket, a crystal, a coaxial connector, and a vibration damping device for the coaxial connector;

[0022] The mounting bracket is provided with a crystal mounting cavity, and the crystal is disposed in the crystal mounting cavity;

[0023] One wall of the mounting bracket is the installation position, and the installation position is provided with an installation through groove that extends to the crystal mounting cavity. The mounting plate is disposed inside or outside the installation through groove.

[0024] The coaxial connector is mounted on the mounting plate, and one end is connected to the crystal.

[0025] Furthermore, the crystal is disposed within the crystal mounting cavity via an elastic buffer mechanism.

[0026] The beneficial effects of this utility model are that the coaxial connector vibration damping device provided by this utility model is used to fix the coaxial connector at the installation position in a vibration environment. The coaxial connector is indirectly fixed to the mounting rod and the installation position via washers I and II made of elastic deformable material, while the mounting rod and the installation position are rigidly connected. When the installation position vibrates, the vibration at the installation position is not directly transmitted to the coaxial connector, but is buffered and damped by washers I and II before being transmitted to the coaxial connector. This achieves vibration isolation between the coaxial connector and the installation position, reducing the vibration of the coaxial connector. In other words, when the installation position vibrates, it reduces changes in the internal spatial dimensions, shape, and internal stress of the coaxial connector, ensuring the effectiveness of signal transmission.

[0027] In addition, the fixed vibration damping mechanism of this utility model has a simple overall structure, is easy and quick to assemble, and facilitates the disassembly and maintenance of the mounting plate and coaxial connector. Attached Figure Description

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0037] As attached Figure 1 -Appendix Figure 3 As shown, this utility model provides a coaxial connector vibration damping device, which can be used for the fixed installation of coaxial connectors in crystal oscillators, and can also be used for the fixed installation of coaxial connectors in microwave modules. It includes a mounting plate 1 and a plurality of fixed vibration damping mechanisms 2. The plurality of fixed vibration damping mechanisms 2 are arranged in a ring array on the mounting plate 1, or the plurality of fixed vibration damping mechanisms 2 are symmetrically arranged on the mounting plate 1, so as to ensure the support stability of the plurality of fixed vibration damping mechanisms 2 on the mounting plate 1.

[0038] The mounting plate 1 is used to fix the coaxial connector 3. The mounting plate 1 is also provided with mounting holes 11 for mounting the fixed vibration damping mechanism 2. The number of mounting holes 11 is the same as the number of fixed vibration damping mechanisms 2. Each mounting hole 11 is used to mount one fixed vibration damping mechanism 2. (Refer to the attached document.) Figure 2In one specific embodiment, four mounting holes 11 and fixed vibration damping mechanisms 2 are provided, and the four are arranged in a rectangular symmetrical structure, while the coaxial connector 3 is fixed in the middle of the mounting plate 1, so as to achieve uniform and symmetrical vibration damping support for the coaxial connector 3 by the four fixed vibration damping mechanisms 2.

[0039] The fixed vibration damping mechanism 2 includes a mounting rod 21, washer I 22, washer II 23 and fasteners, wherein washer I 22 and washer II 23 are made of elastic deformable material;

[0040] The mounting rod 21 includes a fixed end and a free end. The fixed end of the mounting rod 21 is fixed to the installation position 41. Specifically, it can be a fixed integral part or a detachable fixed part. The free end to the fixed end of the mounting rod 21 are provided with a fastener mating structure, a limiting boss I 212 and a limiting boss II 213 in sequence.

[0041] The mounting hole 11 is sleeved on the mounting rod 21 between the limiting boss I 212 and the limiting boss II 213, that is, the mounting rod 21 is arranged through the mounting hole 11, and the washer I 22 is disposed between the mounting plate 1 and the limiting boss I 212. Preferably, the washer I 22 is also sleeved on the mounting rod 21, and the limiting boss I 212 is used to restrict the movement of the washer I 22. The washer II 23 is disposed between the mounting plate 1 and the limiting boss II 213. Preferably, the washer II 23 is also sleeved on the mounting rod 21, and the limiting boss II 213 is used to restrict the movement of the washer II 23.

[0042] The fastener is detachably mounted on the fastener mating structure to prevent the washer I22 from disengaging from the limiting boss I212. At this time, the outer diameter of the limiting boss I212 is slightly larger than the inner diameter of the washer I22 and the washer II23. This arrangement makes it easier to fit the washer I22 and the washer II23 onto the mounting rod 21, thereby simplifying the installation difficulty of the entire coaxial connector vibration damping device.

[0043] The coaxial connector vibration damping device provided by this utility model is used to fix the coaxial connector 3 to the installation position 41 in a vibration environment. The coaxial connector 3 is indirectly fixed to the mounting rod 21 and the installation position 41 by washers I 22 and II 23 made of elastic deformable material. The mounting rod 21 and the installation position 41 are rigidly connected. When the installation position 41 vibrates, the vibration at the installation position 41 is not directly transmitted to the coaxial connector 3, but is buffered and damped by washers I 22 and II 23 before being transmitted to the coaxial connector 3. This achieves vibration isolation between the coaxial connector 3 and the installation position 41, reducing the vibration of the coaxial connector 3. In other words, when the installation position 41 vibrates, it reduces changes in the internal spatial dimensions, shape, and internal stress of the coaxial connector 3, ensuring effective signal transmission.

[0044] In addition, the fixed vibration damping mechanism 2 of this utility model has a simple overall structure, is easy and quick to assemble, and facilitates the disassembly and maintenance of the mounting plate 1 and the coaxial connector 3.

[0045] In one embodiment, the size of the mounting hole 11 is larger than the size of the mounting rod 21;

[0046] The washer I 22 or washer II 23 is provided with a protruding buffer ring 25 for fitting into the gap between the mounting hole 11 and the mounting rod 21. The buffer ring 25 is also made of an elastic deformable material, and the outer wall of the buffer ring 25 is adapted to the wall of the mounting hole 11. In this embodiment, the mounting hole 11 and the mounting rod 21 can be isolated by the buffer ring 25, further reducing the transmission of vibration on the mounting rod 21 to the mounting plate 1 and the coaxial connector 3, and improving the vibration isolation effect. Preferably, refer to the attached figure. Figure 1 The buffer ring 25 is integrally set on the lower washer II 23, further simplifying the installation process.

[0047] In one embodiment, the fastener mating structure is an external thread 211, and the fastener is a nut I 24, which facilitates the installation and disassembly of the fastener. Moreover, the threaded mating has a self-locking characteristic, which can ensure the fixation stability of the fastener after installation. In other embodiments, the fastener mating structure and the fastener can also adopt structures such as snap-fit ​​slots, adhesive blocks, etc.

[0048] The size of the nut I24 is larger than the size of the limiting boss I212. Therefore, after the nut I24 is engaged with the external thread 211, it can help the limiting boss I212 to limit the position of the washer I22.

[0049] In one embodiment, the fixed end of the mounting rod 21 is detachably engaged with the installation position 41, thereby facilitating the assembly and disassembly of the entire fixed vibration damping mechanism 2.

[0050] In one embodiment, a fixing hole 42 is provided on the installation position 41, and a screw 26 is provided on the end of the mounting rod 21 away from the limiting boss II 213;

[0051] The screw 26 is threadedly connected to the fixing hole 42, or the screw 26 passes through the fixing hole 42 and is screwed with a nut II 27, which simplifies the difficulty of detaching and installing the fixing end of the mounting rod 21 and the installation position 41.

[0052] In one embodiment, the limiting boss II 213 abuts against the surface of the installation position 41. In this embodiment, the limiting boss II 213 is used to limit the axial position of the washer II 23 on the one hand, and on the other hand, it can be used to fix and limit the fixed end of the mounting rod 21 when it is fixed on the installation position 41, so that the multiple fixed vibration damping mechanisms 2 are assembled at the same height, further simplifying the installation difficulty of this coaxial connector vibration damping device.

[0053] In one embodiment, the mounting plate 1 has a through hole 12 in the middle, which is used to pass through the coaxial connector 3;

[0054] The coaxial connector 3 is provided with a flange 31 on one side of the through hole 12, and the flange 31 is detachably connected to the mounting plate 1. In this embodiment, the coaxial connector 3 is detachably connected to the mounting plate 1, which facilitates the individual disassembly, assembly, and maintenance of the coaxial connector 3.

[0055] In one embodiment, the flange 31 is connected to the mounting plate 1 by bolt fasteners to simplify disassembly and assembly.

[0056] This utility model also provides a crystal oscillator, including a mounting bracket 4, a crystal 5, a coaxial connector 3, and the aforementioned coaxial connector vibration damping device;

[0057] The mounting bracket 4 is provided with a crystal mounting cavity 44, and the crystal 5 is disposed on the crystal mounting cavity 44;

[0058] One wall of the mounting bracket 4 is the installation position 41. The installation position 41 is provided with an installation through slot 43 that extends through the crystal mounting cavity 44. The installation through slot 43 is used to allow the coaxial connector 3 to extend out of the crystal mounting cavity 44. The mounting plate 1 is provided inside or outside the installation through slot 43. Preferably, the mounting plate 1 is provided inside the installation through slot 43 to provide basic and simple physical protection for the coaxial connector vibration damping device through the crystal mounting cavity 44. At this time, the nut II 27 is also provided on the outer wall of the mounting bracket 4 to facilitate the cooperation between the nut II 27 and the screw 26.

[0059] The coaxial connector 3 is disposed on the mounting plate 1, and one end is connected to the crystal 5 to realize the connection between the coaxial connector 3 and the crystal 5.

[0060] In one embodiment, the crystal 5 is disposed in the crystal mounting cavity 44 by an elastic buffer mechanism. Preferably, the crystal 5 is fixed on the crystal mounting cavity 44 by an elastic buffer structure.

[0061] The specific installation steps for this crystal oscillator are as follows:

[0062] S1, the coaxial connector 3 is fixed to the mounting plate 1 via flange 31;

[0063] S2, the washer II23 with the buffer protrusion 25 is passed through the limiting boss I212 and fitted onto the mounting rod 21 within the range of the limiting boss I212 to the limiting boss II213, with the buffer protrusion 25 facing the limiting boss I212;

[0064] S3, pass the screws 26 of the multiple fixed vibration damping mechanisms 2 through the fixing holes 42 of the mounting bracket 4 until the limiting boss II 213 abuts against the inner wall of the crystal mounting cavity 44, and then tighten the nut II 27 to complete the installation of multiple mounting rods 21 and the position to be installed 41;

[0065] S4, the mounting holes 11 of the mounting plate 1 are matched one by one with the mounting rods 21, and then the mounting holes 11 are fitted onto the corresponding mounting rods 21, and then cooperate with the buffer ring 25 after passing through the limiting boss I 212.
