Description

Technical Field

[0001] This utility model relates to a fine-tuning carrier bar for a quartz resonator. Background Technology

[0002] With the continuous development of mobile communication, the 5G era has arrived. Quartz crystal resonators are also moving towards higher frequency bands, making the manufacturing process increasingly stringent. For high, medium, and low frequency quartz crystal resonators, fine-tuning is an indispensable part of production. Each time a new frequency band is introduced, the fine-tuning carrier strip needs to be replaced, and different frequency bands require different fine-tuning holes. A large number of fine-tuning carrier strips are needed to keep up with production. During the fine-tuning process, the fine-tuning holes gradually enlarge, and many holes become irregular in shape, eventually leading to the scrapping of many fine-tuning carrier strips. This significantly increases production costs in the workshop. Currently, the fine-tuning carrier strips are of an integral structure; when a carrier strip becomes unusable, the entire unit needs to be replaced, further increasing replacement and production costs. Utility Model Content

[0003] The purpose of this invention is to solve the problem of high replacement costs when existing fine-tuning carriers are replaced due to their integral structure. This invention proposes a quartz resonator fine-tuning carrier, which is a carrier body assembled from a base plate, a mask, and a cover plate. When the fine-tuning hole deforms or enlarges, only the mask needs to be replaced. This reduces replacement costs and allows for the assembly of masks of different specifications according to different frequency bands of quartz crystal resonators, thereby greatly reducing production costs.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a quartz resonator fine-tuning carrier strip, including a carrier strip body, the carrier strip body including a base plate, a mask and a cover plate, the mask is provided with fine-tuning holes, the mask is disposed between the base plate and the cover plate, a positioning connection structure is provided between the base plate and the cover plate, and the mask is provided with an installation structure that cooperates with the positioning connection structure.

[0005] Preferably, the positioning connection structure includes mutually cooperating positioning pins and positioning holes. There are two positioning pins symmetrically distributed at both ends of the base plate. The positioning holes are set on the cover plate and are corresponding to the positioning pins. The mounting structure includes a first through hole that cooperates with the positioning pins. The positioning pin passes through the first through hole and is inserted into the positioning hole.

[0006] Preferably, the top end of the positioning pin is rounded; and / or, the bottom end of the positioning hole is chamfered. The rounded corners and chamfers help reduce the difficulty of inserting the positioning pin into the positioning hole, allowing the base plate and cover plate to be installed smoothly during positioning, thus reducing the difficulty of positioning between the base plate and cover plate.

[0007] Preferably, the positioning pin and the base plate are an integral structure.

[0008] Preferably, the positioning connection structure further includes corresponding first connection holes and second connection holes. The first connection holes are provided in multiple and spaced apart on the base plate, and the second connection holes are provided in multiple and spaced apart on the cover plate. The mounting structure includes a second through hole corresponding to the first connection hole. Screws for connecting the base plate and the cover plate pass through the first connection hole and the second through hole and are tightened in the second connection hole.

[0009] Preferably, the first connecting hole is a threaded hole or a round hole, and the second connecting hole is a threaded hole.

[0010] Preferably, the bottom end of the cover plate is provided with a groove that matches the mask.

[0011] In summary, the advantages of this utility model are as follows: The carrier strip body is configured as a base plate, mask, and cover plate. Since the micro-adjustment hole is located on the mask, when the micro-adjustment hole deforms or enlarges, replacement can be achieved simply by replacing the mask, reducing replacement costs. Furthermore, it allows for the assembly of masks of different specifications according to quartz crystal resonators of different frequency bands, significantly reducing production costs and improving overall production efficiency. Secondly, the positioning connection structure effectively positions the base plate and cover plate during assembly, reducing assembly difficulty and improving assembly efficiency. This positioning connection structure also effectively improves the structural stability of the base plate and cover plate after assembly, enhancing overall stability. Additionally, the installation structure on the mask, which cooperates with the positioning connection structure, prevents mask fixation during assembly, avoiding mask displacement and improving overall installation quality.

[0014] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a quartz resonator fine-tuning carrier includes a carrier body 1, which includes a base plate 2, a mask 3, and a cover plate 4. The mask 3 is provided with fine-tuning holes 30, and the base plate and the cover plate are provided with adjustment holes corresponding to the fine-tuning holes. The mask 3 is disposed between the base plate 2 and the cover plate 4, and a positioning connection structure 5 is provided between the base plate 2 and the cover plate 4. The mask 3 is provided with an installation structure 31 that cooperates with the positioning connection structure 5 for installation.

[0015] The carrier strip body 1 is configured as a base plate 2, a mask 3, and a cover plate 4. Since the micro-adjustment hole 30 is located on the mask 3, when the micro-adjustment hole 30 deforms or becomes larger, it can be replaced simply by replacing the mask 3. This reduces replacement costs and allows for the assembly of masks 3 of different specifications according to quartz crystal resonators of different frequency bands, thereby greatly reducing production costs and improving overall production efficiency. Secondly, the positioning connection structure 5 can effectively position the base plate 2 and the cover plate 4 during assembly, which helps to reduce the assembly difficulty of the base plate 2 and the cover plate 4, thereby improving the assembly efficiency of both. The positioning connection structure 5 can effectively improve the structural stability of the base plate 2 and the cover plate 4 after assembly, which helps to improve the overall stability. In addition, the installation structure 31 on the mask 3, which is installed in conjunction with the positioning connection structure 5, can prevent the mask 3 from being fixed during assembly and prevent the mask 3 from shifting during assembly, thus improving the overall installation quality.

[0016] The positioning connection structure 5 includes a positioning pin 51 and a positioning hole 52 that cooperate with each other. Two positioning pins 51 are provided and symmetrically distributed at both ends of the base plate 2. The positioning hole 52 is provided on the cover plate 4 and corresponds to the positioning pin 51. The mounting structure 31 includes a first through hole 32 that cooperates with the positioning pin 51. The positioning pin 51 passes through the first through hole 32 and is inserted into the positioning hole 52. The cooperation structure of the positioning pin 51 and the positioning hole 52 achieves positioning between the base plate 2 and the cover plate 4 during assembly. The overall structure is simple and easy to assemble. The top end of the positioning pin 51 has a rounded corner 53, and the bottom end of the positioning hole 52 has a chamfer 54. The rounded corner 53 and chamfer 54 help reduce the difficulty of inserting the positioning pin into the positioning hole 52, allowing the base plate 2 and the cover plate 4 to be installed smoothly during positioning, thus reducing the positioning difficulty between the base plate 2 and the cover plate 4. The positioning pin 51 and the base plate 2 are an integral structure, which simplifies the installation structure 31 between the positioning pin 51 and the base plate 2 and improves the connection strength between the positioning pin 51 and the base plate 2.

[0017] The base plate 2 and the cover plate 4 are fixedly connected by screws. Specifically, the positioning connection structure 5 also includes corresponding first connecting holes 55 and second connecting holes 56. Multiple first connecting holes 55 are provided and spaced apart on the base plate 2, and multiple second connecting holes 56 are provided and spaced apart on the cover plate 4. The mounting structure 31 includes a second through hole 33 corresponding to the first connecting hole 55. Screws used to connect the base plate 2 and the cover plate 4 pass through the first connecting hole 55 and the second through hole 33 and are tightened into the second connecting hole 56, facilitating assembly and improving the connection strength between the base plate 2 and the cover plate 4, thus facilitating subsequent replacement of the mask 3. The first connecting hole 55 is a threaded hole or a round hole, and the second connecting hole 56 is a threaded hole. Setting the first connecting hole 55 as a threaded hole or a round hole allows for different structures to be set according to different installation requirements. In this embodiment, a round hole is preferred to facilitate screw insertion. Setting the second connecting hole 56 as a threaded hole enables screw tightening, improving the reliability of the installation of the cover plate 4 and the base plate 2. The bottom end of the cover plate 4 is provided with a groove 41 that matches the mask 3, which can improve the overall positioning accuracy and improve the sealing performance between the base plate 2 and the cover plate 4.
