[0002] In electronic equipment and communication systems, the resonator is an important component, and the stability of its installation directly affects the performance of the entire system. At present, countersunk screws are widely used to fix the resonator during installation to ensure that it can maintain stable performance during operation. However, in practical applications, due to the tolerance of the angles of the countersunk hole and the countersunk surface of the countersunk screw during the manufacturing process, this will cause the contact state between the two to be not an ideal surface contact, but a line and surface contact. As a result, the resonator may vibrate or displace during operation, resulting in poor installation stability and even affecting its performance. In addition, line contact may also cause stress concentration on the countersunk screw when it is subjected to force, thereby accelerating its wear and damage. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] The present application extends a base into the cavity at the bottom center of the cavity, places the resonator on the base, and a countersunk hole is opened at the bottom of the resonator. A countersunk screw passes through the countersunk hole and is limited by the countersunk hole. An annular soft metal gasket is provided between the countersunk hole and the countersunk screw. The soft metal gasket can ensure that the countersunk screw and the soft metal gasket are in surface contact through deformation, and the resonator and the soft metal gasket are also in surface contact.

In addition, the soft metal gasket achieves surface contact on both sides, which can reduce the wear of the countersunk screw caused by stress concentration due to force.

[0021] Embodiment 1

[0022] Combination Figures 1 to 3 As shown, an embodiment of the utility model provides a resonator mounting structure, including a cavity 1 and a resonator 2 arranged inside the cavity 1, a base 101 extends into the cavity from the bottom center of the cavity 1, the resonator 2 is placed on the base 101, and the bottom of the resonator 2 includes a countersunk hole with a countersunk screw 3, and an annular soft metal gasket 4 is provided between the countersunk hole and the countersunk screw 3.

[0023] Specific, combined Figure 1 and Figure 2 As shown, the outer facade of the cavity 1 is rectangular, and the inner facade is circular. The inner facade is formed into a circular shape so that the inner facade can be adapted to the circular shape of the resonator 2, thereby forming a uniform resonant cavity. The center of the bottom of the cavity 1 bulges into the cavity, and a base 101 is extended. The upper end surface of the base 101 contacts the bottom surface of the resonator 2 to support and install the resonator 2. The two contact surfaces of the base 101 and the resonator 2 can be in complete contact or incomplete contact. For example, when the contact area of the annular upper end surface of the base 101 is smaller than the contact area of the bottom surface of the resonator 2, incomplete contact is formed.

[0024] More specifically, a countersunk hole (not shown in the figure) is provided in the bottom of the resonator 2, and the annular diameter of the countersunk hole gradually decreases from top to bottom, forming a funnel shape. The countersunk hole is used to limit the countersunk head of the countersunk screw 3, so that the countersunk head of the countersunk screw 3 is placed at the bottom of the resonator 2, and the threaded portion of the countersunk screw 3 is placed in the base 101, so that the resonator 2 and the base 101 are fixed by the countersunk screw 3.

[0025] More specifically, the soft metal gasket 4 can be formed by electroplating a soft metal material. The soft metal material includes, but is not limited to, conductive glue, silver, aluminum, copper, etc. An annular soft metal gasket 4 is provided between the countersunk hole and the countersunk screw 3. In order to achieve a tight connection between the countersunk head of the countersunk screw 3 and the annular surface of the countersunk hole, the countersunk screw 3 is rotated and force is applied to squeeze the soft metal gasket 4 to produce deformation. After the deformation, the soft metal gasket 4 is filled into each gap between the countersunk head and the annular surface of the countersunk hole, thereby ensuring that the countersunk screw 3 and the soft metal gasket 4 form a surface-to-surface contact, and ensuring that the resonator 2 and the soft metal gasket 4 are also in surface-to-surface contact. By adding the soft metal gasket 4 as a medium, the annular surface of the countersunk hole of the resonator 2 and the countersunk screw 3 are indirectly in surface-to-surface contact, which is more conducive to ensuring the stability of the resonator installation and avoiding the performance of the resonator being affected by the instability of the resonator installation. In addition, both sides of the soft metal gasket 4 are in surface-to-surface contact, which can reduce the wear of the countersunk screw 3 caused by stress concentration due to the force.

[0026] In the embodiment of the utility model, a base 101 is extended into the cavity from the bottom center of the cavity 1, and the resonator 2 is placed on the base 101, and a countersunk hole is opened at the bottom of the resonator 2, and a countersunk screw 3 passes through the countersunk hole and is limited by the countersunk hole, and an annular soft metal gasket 4 is provided between the countersunk hole and the countersunk screw 3. The soft metal gasket 4 can ensure that the countersunk screw 3 and the soft metal gasket 4 are in surface contact through deformation, and the resonator 2 and the soft metal gasket 4 are also in surface contact, which can ensure the stability of the resonator installation and avoid affecting its performance due to the unstable installation of the resonator; in addition, the soft metal gasket 4 achieves surface contact on both sides, which can reduce the wear of the countersunk screw 3 caused by stress concentration caused by the force.

[0027] Embodiment 2

[0028] Combination Figure 1 and Figure 3 As shown, in this embodiment, the annular surface shape of the soft metal gasket 4 is set corresponding to the countersunk hole and the countersunk surface shape of the countersunk screw 3.

[0029] Specifically, since the countersunk hole and the countersunk surface of the countersunk screw 3 are funnel-shaped, the soft metal gasket 4 is set to be funnel-shaped, which is consistent with the size of the annular surface of the countersunk hole to achieve complete fit, which is more conducive to completely wrapping the countersunk surface of the countersunk screw 3 on the annular surface to ensure overall stability in the circumferential direction. The thickness of the soft metal gasket 4 can be selected according to the angle tolerance and spacing between the annular surface of the countersunk hole and the countersunk surface of the countersunk screw 3.

[0030] Embodiment 3

[0031] Combination Figure 1 and Figure 3 As shown, in this embodiment, the base 101 is an annular structure with a mounting groove 1011 defined in the center, and the threaded portion of the countersunk screw 3 is placed in the mounting groove 1011 .

[0032] Specifically, in order to ensure that the installation of the resonator 2 is more stable, the structure of the base 101 needs to be compatible with the structure of the resonator 2. For this purpose, the base 101 can be set as a ring structure so as to fit more stably with the bottom surface of the resonator 2. The above-mentioned installation groove 1011 can be a cylindrical groove, the diameter of the cylinder is greater than or equal to the diameter of the threaded portion of the countersunk screw 3, and the depth of the installation groove 1011 can at least accommodate the threaded portion of the countersunk screw 3 to ensure that the threaded portion of the countersunk screw 3 can smoothly enter the installation groove 1011, so that the resonator 2 is fixedly connected to the cavity 1 through the countersunk screw 3 to ensure the stability of the installation.

[0033] Embodiment 4

[0034] Combination Figure 3 As shown, in this embodiment, after the annular surface at the upper end of the base 101 abuts against the contact surface at the bottom of the resonator 2, an annular cavity 5 is formed between the base 101 and the resonator 2, and the mounting groove 1011 is located at the center of the annular cavity 5 and extends to the lower end of the base 101.

[0035] Specifically, after the resonator 2 and the base 101 are installed, an annular cavity 5 is formed between the two, and the annular cavity 5 is circumferentially arranged on the upper surface of the installation groove 1011. The formation of the annular cavity 5 is beneficial in practical applications because the resonator 2 will generate heat due to operation. The annular cavity 5 can be used as a part of thermal management to ensure that the resonator 2 operates within a normal operating temperature range.

[0036] Embodiment 5

[0037] Combination Figure 3 As shown, in this embodiment, the resonator 2 includes a resonant cavity 201 , a countersunk hole is provided at the bottom of the resonant cavity 201 , and the head of the countersunk screw 3 is limited by the countersunk hole and the soft metal gasket 4 .

[0038] Specifically, by setting a countersunk hole at the bottom center of the resonant cavity 201, after the countersunk screw 3 is passed through the countersunk hole, the soft metal gasket 4 is used for limiting to ensure that the countersunk screw 3 and the countersunk hole of the resonator 2 are in surface-to-surface contact, thereby enhancing the stability and sealing of the connection.

[0039] Embodiment 6

[0040] Combination Figure 1 and Figure 2As shown, in this embodiment, a tuning cover plate 6 is provided on the top of the cavity 1, and the tuning cover plate 6 is connected to the upper end of the ring wall of the cavity 1 through a plurality of connectors 7; a through hole is provided at the position of the tuning cover plate 6 corresponding to the resonant cavity 201, and a tuning screw 8 is passed through the through hole, and one end of the tuning screw 8 facing the cavity is directly opposite to the resonant cavity 201.

[0041] Specifically, the tuning cover plate 6 is rectangular and matches the shape of the cavity 1 so as to encapsulate the upper surface of the cavity 1. When encapsulating, it can be fixed by evenly arranging multiple connectors 7 at various connection positions. For example, two holes are respectively opened on the four sides of the tuning cover plate 6, and grooves are respectively opened at positions corresponding to the holes opened on the upper surface of the cavity 1 and the tuning cover plate 6. The holes and grooves at the corresponding positions are fixedly connected by bolts and nuts. Among them, the tuning cover plate 6 can affect the resonant cavity inside the filter through its deformation and fine adjustment, so that the frequency resonates with the resonant cavity through the resonator 2, thereby achieving the effect of generating frequency and being tunable. The tuning cover plate 6 adopts a nut with damping, and the damping is embedded in one side of the nut. When the bolt passes through the nut, the end of the bolt first contacts the internal thread of the nut, and finally penetrates the damping for self-locking. In this way, metal debris adhering to the end of the bolt can be filtered out and accumulated in the nut, thereby reducing interference with the internal signal of the resonator 2.

[0042] More specifically, a through hole (not shown in the figure) can be opened at the center of the tuning cover plate 6 at a position corresponding to the resonator 2, and the tuning screw 8 is passed through the through hole, and one end facing the cavity 1 is directly opposite to the resonant cavity 201 of the resonator 2. The tuning screw 8 is applied to the resonator 2, and the resonant frequency can be effectively tuned by changing the length of the tuning screw 8. When the tuning screw 8 is lengthened, the resonant frequency will move down; when the tuning screw 8 is shortened, the resonant frequency will move up. The high adjustability enables the resonator 2 to accurately adapt to different frequency requirements, and by accurately adjusting the tuning screw 8, it can be ensured that the resonator 2 works in the best state, thereby improving the performance of the applied product.

[0043] Embodiment 7

[0044] Combination Figure 1 and Figure 2 As shown, in this embodiment, a first connector 9 and a second connector 10 fixed based on a fixing member 11 and symmetrically arranged are connected to the side wall of the cavity 1; the first connector 9 and the second connector respectively include a connecting portion 901 and a fixing portion 902 extending laterally from the middle of the connecting portion 901, the fixing portion 902 is provided with a fixing hole, and the side wall of the cavity 1 is provided with a first mounting hole and a second mounting hole, one end of the connecting portion 901 is penetrated into the first mounting hole, and the fixing hole and the second mounting hole are connected by the fixing member 11; the connecting portion 901 and the fixing portion 902 are an integrally formed structure.

[0045] Specifically, connectors can be respectively arranged on opposite surfaces of the cavity 1, the connector on one side is the first connector 9, and the connector on the opposite surface is the second connector 10. The above-mentioned fixing member 11 can be a bolt, a screw, etc. Each connector includes a fixing portion 902 and a connecting portion 901, the fixing portion 902 is perpendicular to the connecting portion 901, and extends laterally from both sides of the middle section of the connecting portion 901, and the connecting portion 901 and the fixing portion 902 are an integrally formed structure. Fixing holes are respectively provided on both sides of the fixing portion 902, and a second mounting hole (not shown in the figure) is provided on the side wall of the cavity 1 corresponding to the size of the fixing hole, and a first mounting hole (not shown in the figure) is provided corresponding to the size of the connecting portion 901. In this way, it can be ensured that the first mounting hole is penetrated at one end of the connecting portion 901, and the fixing member 11 is penetrated with the fixing hole and the second mounting hole at the same time, so that the connector is fixedly connected to the cavity 1. Among them, the first connector 9 and the second connector 10 are mainly used to realize the physical connection and electrical connection between the resonator 2 and other electronic components or systems, and are helpful to ensure the stable operation of the resonator 2, improve the system performance and meet the specific application requirements.

[0046] In the embodiment of the utility model, a base 101 is extended into the cavity from the bottom center of the cavity 1, and the resonator 2 is placed on the base 101, and a countersunk hole is opened at the bottom of the resonator 2, and the countersunk screw 3 passes through the countersunk hole and is limited by the countersunk hole. An annular soft metal gasket 4 is provided between the countersunk hole and the countersunk screw 3. The soft metal gasket 4 can ensure that the countersunk screw 3 and the soft metal gasket 4 are in surface-to-surface contact through deformation, and the resonator 2 and the soft metal gasket 4 are also in surface-to-surface contact, so that the stability of the resonator installation can be ensured, and the performance of the resonator can be avoided from being affected by the unstable installation of the resonator; in addition, the soft metal gasket 4 realizes surface-to-surface contact on both sides, which can reduce the wear caused by the stress concentration of the countersunk screw 3 due to the force. By setting the annular surface shape of the soft metal gasket 4 to correspond to the countersunk hole and the countersunk surface shape of the countersunk screw 3, it is more conducive to completely wrapping the countersunk surface of the countersunk screw 3 on the annular surface, and ensuring the overall stability in the circumferential direction. By making the base 101 into an annular structure, a mounting groove 1011 is opened in the center, and the threaded portion of the countersunk screw 3 is placed in the mounting groove 1011, it can ensure that the installation of the resonator 2 is more stable. By forming the annular cavity 5, a heat dissipation space can be provided for the resonator 2. By arranging the tuning screw 8 on the resonant cover plate, the resonant frequency can be effectively tuned to accurately meet different frequency requirements. By arranging the first connector 9 and the second connector 10 on the opposite surfaces of the cavity 1, physical and electrical connections with other external electronic components or systems can be achieved.
