DETAILED DESCRIPTION
[0035] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0036] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can, for example, be implemented in an order other than those illustrated or described herein.
[0037] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.
[0038] In the description of the embodiments of the present application, it should be understood that the terms "inside", "outside", "top", "bottom", "front", "back", etc. indicating the orientation or position relationship (if any) are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.
[0039] The resonator exists as an independent device after being packaged. The number of pins of the resonator varies depending on its function and packaging form. Therefore, when it is necessary to measure and calibrate the resonator in a special environment, the resonator needs to be soldered on a circuit board and made to work through a circuit that matches the resonator, so as to determine whether the resonator meets the design requirements.
[0040] When soldering the resonator to the circuit board, the iron sheet welding method is often used. This method requires the production of circuit boards, steel meshes, iron sheets, etc. that match the resonator, which is time-consuming and labor-intensive. In addition, the welding process requires multiple heating and cooling, which may damage the resonator itself and affect the test results. The resonator after the test can no longer be used for other products, resulting in great waste. In addition, there is no special adapter for resonator packaging in the prior art, so when testing the resonator, connection becomes the biggest problem.
[0041] Therefore, the embodiment of the present application provides a resonator fixing device to fix the resonator. When fixing the resonator, no welding materials are needed, and no heating and cooling are required. The resonator after testing can continue to be used in other products. The resonator fixing device provided by the present application will be further described below in conjunction with the accompanying drawings.

Figure 4 for Figure 3 Schematic diagram of the structure in which the second spring is arranged below the substrate. Figure 5 This is a schematic diagram of the structure of the metal pressing plate in the resonator fixing device provided in this application.
[0043] like Figure 1 As shown, an embodiment of the present application provides a resonator fixing device, including a substrate 100 , a metal pressing sheet 200 , a first electrode 300 , a second electrode 400 and a fixing assembly 500 , and a limiting portion 110 is provided on the substrate 100 .
[0044] The first electrode 300 is disposed in the limiting portion 110 . When the resonator 600 is installed in the limiting portion 110 , the housing of the resonator 600 abuts against the first electrode 300 .
[0045] The metal pressing sheet 200 is configured such that one end abuts against the pin 610 of the resonator 600 and the other end is connected to the substrate 100 via the fixing assembly 500 . The metal pressing sheet 200 is used to fix the resonator 600 in the limiting portion 110 .
[0046] The second electrode 400 is disposed on the metal pressing sheet 200 , and the second electrode 400 is used to connect with the test circuit.
[0047] In the embodiment of the present application, the resonator 600 is fixed on the first surface of the substrate 100 by the metal pressing sheet 200, and then the external test circuit is connected through the metal pressing sheet 200 and the second electrode 400, so as to realize the circuit connection. Since the present application does not need to heat up and cool down the resonator 600, the resonator 600 will not be damaged, thus ensuring the accuracy of the test. It is also convenient for the resonator 600 to be processed into other components for use, and it is also convenient to take the resonator 600.
[0048] The substrate 100 may be a glass fiber reinforced epoxy resin substrate, a ceramic substrate, a high frequency substrate material, a metal substrate, etc., and may be configured according to specific needs.
[0049] The limiting portion 110 is used to limit the resonator 600 on the first surface of the substrate 100 to prevent the resonator 600 from moving along the first surface of the substrate 100 , while leaving an installation opening for the resonator 600 so that the resonator 600 can be installed in the limiting portion 110 .
[0050] The first electrode 300 is disposed at the bottom of the limiting portion 110 . The first electrode 300 is a plate-like structure and can be made of materials such as copper and aluminum. The area of the first electrode 300 is greater than or equal to the area of the bottom of the limiting portion 110 to ensure better contact between the resonator 600 housing and the first electrode 300 .
[0051] A through hole connected to the first electrode 300 is formed at the bottom of the limiting portion 110 . The first electrode 300 can be connected to an external circuit through the through hole. The first electrode 300 is used for shielding and grounding.
[0052] After one end of the metal pressing sheet 200 is fixed by the fixing component 500, the other end is pressed on the pin 610 of the resonator 600 to fix the resonator 600 in the limiting portion 110, and the connection between the resonator 600 and the test circuit is achieved through the conductivity of the metal pressing sheet 200 itself, so that the test circuit can be connected to the resonator 600 by only connecting the second electrode 400 on the metal pressing sheet 200, and there is no need to set up an additional resonator 600 adapter.
[0053] The test circuit is used to test the voltage and current of the resonator 600 .
[0054] Continue as Figure 1 As shown, in the embodiment of the present application, the limiting portion 110 includes a limiting groove 111, the limiting groove 111 is arranged on the first surface of the substrate 100, the first electrode 300 is arranged at the bottom of the limiting groove 111, and at least part of the resonator 600 is located in the limiting groove 111.
[0055] In the embodiment of the present application, the top surface of the substrate 100 is the first surface, the limiting groove 111 is formed by a cavity that is recessed inward from the first surface, and the groove wall of the limiting groove 111 is perpendicular to the first surface.
[0056] The metal pressing sheet 200 is an elastic pressing sheet, which presses the top of the resonator 600 through its own deformation force, thereby fixing the resonator 600.
[0057] In order to facilitate the subsequent removal of the resonator 600 , the height of the limiting groove 111 is less than two-thirds of the height of the resonator 600 .
[0058] like Figure 2As shown, in the embodiment of the present application, the limiting portion 110 includes two limiting blocks 112 , both of which are arranged on the first surface of the substrate 100 , the first electrode 300 is arranged between the two limiting blocks 112 , and at least part of the resonator 600 is located between the two limiting blocks 112 .
[0059] In the embodiment of the present application, the top surface of the substrate 100 is the first surface, and the side wall of the limiting block 112 is perpendicular to the first surface.
[0060] The first surface of the substrate 100 is provided with a mounting groove (not marked in the figure), and the mounting groove is used to install the first electrode 300 so that the top surface of the first electrode 300 is parallel to the first surface of the substrate 100 to avoid the first electrode 300 affecting the installation of the resonator 600.
[0061] The height of the limit block 112 can be the same as the height of the resonator 600. The resonator 600 is located between the two limit blocks 112. The resonator 600 is fixed by clamping the two limit blocks 112 to prevent the resonator 600 from moving. Since the limit blocks 112 only fix the two sides of the resonator 600, resonators 600 of different lengths can be fixed.
[0062] Combination Figure 2 and Figure 6 As shown, in the embodiment of the present application, a slide groove 120 is provided in the substrate 100, a first spring 130 is provided in the slide groove 120, at least part of the limit block 112 is provided in the slide groove 120 and connected to the first spring 130, and the limit block 112 moves toward the resonator 600 under the action of the first spring 130.
[0063] The resonator 600 is fixed by pushing the limiting block 112 through the elastic force of the first spring 130 , and the distance between the two limiting blocks 112 can also be controlled by moving the limiting block 112 , so as to fix the resonators 600 of different widths.
[0064] A gasket 113 is provided on the side wall of the limiting block 112 that contacts the resonator 600 , and the gasket 113 plays a buffering role.
[0065] When fixing the resonator 600, pull the two limit blocks 112 to move. When the distance between the two limit blocks 112 is sufficient to place the resonator 600, place one end of the shell of the resonator 600 on the first electrode 300, loosen the two limit blocks 112, and the limit blocks 112 squeeze the resonator 600 under the action of the first spring 130, and then press the metal pressing sheet 200 onto the pin 610 of the resonator 600 to achieve fixation.
[0066] Combination Figure 1 and Figure 2As shown, in the embodiment of the present application, the fixing assembly 500 includes a bolt 510 and a nut 520 , and the bolt 510 passes through the metal pressing sheet 200 and the substrate 100 in sequence and is connected to the nut 520 to fix the metal pressing sheet 200 on the substrate 100 .
[0067] Among them, through holes are correspondingly provided on the substrate 100 and the metal pressing plate 200, and the bolts 510 pass through the through holes on the substrate 100 and the metal pressing plate 200 in turn and are connected with the nuts 520. When installing the resonator 600, it is only necessary to lift the metal pressing plate 200.
[0068] In the embodiment of the present application, the fixing assembly 500 further includes a second spring 530 , and the second spring 530 is disposed on the screw rod of the bolt 510 .
[0069] like Figure 3 As shown, illustratively, the bolt head of the bolt 510 is located above the base plate 100 , and the second spring 530 is located on the screw rod between the bolt head and the base plate 100 . The metal pressing sheet 200 can be further compressed by the spring force of the second spring 530 .
[0070] like Figure 4 As shown, illustratively, the bolt head of the bolt 510 is located above the substrate 100, and the second spring 530 is located on the screw between the nut 520 and the second surface of the substrate 100. The bolt 510 can be raised by pressing the nut 520 to release the metal pressing sheet 200, and the metal pressing sheet 200 can be restored after loosening the nut 520. The second spring 530 can release the metal pressing sheet 200 by pressing the nut 520, which makes it easier to install the resonator 600.
[0071] In the embodiment of the present application, the second surface is the bottom surface of the substrate 100 .
[0072] In an embodiment of the present application, the metal pressing sheet 200 includes a fixing portion 210 and a plurality of abutting portions 220 arranged on the fixing portion 210 . The fixing portion 210 is fixed to the first surface of the substrate 100 through a fixing component 500 , and the plurality of abutting portions 220 abut against a plurality of pins 610 of the resonator 600 .

The second electrode 400 is arranged at the top or bottom of the fixed portion 210.
[0074] The plurality of abutting portions 220 are used to abut against the plurality of pins 610 of the resonator 600 , so that the metal pressing sheet 200 can adapt to more types of resonators 600 .
[0075] In the embodiment of the present application, the metal pressing sheet 200 is a conductive material such as a copper sheet, an aluminum sheet, or an alloy.

[0077] In the embodiment of the present application, the resonator 600 is fixed to the first surface of the substrate 100 by the metal pressing sheet 200, and then the external test circuit is connected to the metal pressing sheet 200 and the second electrode 400, so as to realize the circuit connection. Since the present application does not need to heat up and cool down the resonator 600, the resonator 600 will not be damaged, thus ensuring the accuracy of the test. It is also convenient for the resonator 600 to be processed into other components for use, and it is also convenient to take the resonator 600.
