Description

Technical Field

[0001] This utility model relates to the field of metal cavity filter technology, specifically a turret structure for a small filter cavity. Background Technology

[0002] A filter is a frequency-selective device that allows specific frequency components of a signal to pass through while significantly attenuating other frequency components. Within a defined passband, the filter's attenuation is minimal, ensuring smooth energy transmission; outside the passband, the attenuation increases dramatically, effectively suppressing the transmission of unnecessary energy and thus filtering out interference components that do not match the frequency of the desired transmitted signal.

[0003] As the requirements for products in the communications market become increasingly stringent, and the weight of products becomes more and more demanding, there is a growing number of filters with small cavities and shallow cavities. Conventional press-fit support structures and conventional threaded joint support structures require more space and need to be matched with a custom connecting rod, which increases costs. They cannot be used on filters with shallow cavities.

[0004] Due to increasingly stringent requirements for product size and cost, many products have relatively small cavity depths. The first type, crimping, involves welding the transmission piece to the connector, which is difficult to position and results in poor consistency. The second type, a conventional threaded structure, requires a precision-machined hole at the bottom of the support base to accommodate a rigid connector, increasing processing time. Furthermore, both of these structures require more space, making them unsuitable for products with small cavity depths. They also necessitate custom-made connecting rods matching the cavity depth for connecting the connector and the rigid connector, further increasing costs and failing to meet production needs. Therefore, a turret structure for small filter cavities is proposed to address the aforementioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a turret structure for small filter cavities, which has the advantage of occupying little space. It solves the problems of the two existing structures requiring more space, being unsuitable for products with small cavity depths, and requiring customized connecting rods that match the cavity depth for connecting joints and rigid connectors, resulting in higher costs and failing to meet production needs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a turret structure for a small filter cavity, comprising a filter cavity and a connector disposed on the top of the filter cavity, wherein a transmission plate is disposed inside the filter cavity, and a novel turret structure capable of fixing the transmission plate is disposed inside the filter cavity.

[0007] The novel turret structure includes a novel connector turret disposed on the top of the filter cavity and extending into it. A slot is provided on one side of the bottom end of the novel connector turret, and a limiting notch is provided on the side of the novel connector turret near the filter cavity.

[0008] Furthermore, the novel connector turret is a hollow cylinder, and the filter cavity is pressed and fixed to the novel connector turret using a press.

[0009] Furthermore, the bottom of the connector is fixedly installed on the top of the new connector turret.

[0010] Furthermore, there are two limiting notches, which are symmetrically distributed on the left and right sides of the new connector turret.

[0011] Furthermore, the slot and the limiting notch are parallel to each other.

[0012] Furthermore, the novel connector turret is located on the outer side of the filter cavity, where a pressure plate is fixed, and the limiting notch is located at the bottom of one side of the pressure plate.

[0013] Furthermore, the novel connector turret and connector are fixedly installed by slotting.

[0014] Furthermore, the bottom of the connector extends into the interior of the novel connector turret.

[0015] Furthermore, the outer side of the bottom of the new connector turret is provided with knurled teeth.

[0016] Furthermore, one side of the transmission piece is fixedly connected to the novel connector turret.

[0017] Compared with the prior art, this utility model provides a turret structure for a small filter cavity, which has the following advantages:

[0018] This turret structure for small filter cavities, by incorporating a novel connector turret, allows for the fixed mounting of the connector on its top. The slotted design facilitates a shorter distance between the connector and the filter cavity, thus saving space. Furthermore, the limiting notch allows for easy pressing of the novel connector turret into the filter cavity and also enables the positioning of the transmission plate. The structure is simple, low-cost, and space-efficient, solving the problems of existing structures requiring more space, being unsuitable for products with shallow cavities, and necessitating custom-made connecting rods matching the cavity depth for connecting the connector and rigid connector, resulting in higher costs and failing to meet production requirements.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 2 This embodiment provides a turret structure for a small filter cavity, including a filter cavity 1 and a connector 2 disposed on the top of the filter cavity 1. A transmission plate 3 is disposed inside the filter cavity 1, and a novel turret structure capable of fixing the transmission plate 3 is disposed inside the filter cavity 1. The novel turret structure includes a novel connector turret 4 disposed on the top of the filter cavity 1 and extending into its interior. A slot 41 is provided on one side of the bottom end of the novel connector turret 4, and a limiting notch 42 is provided on the side of the novel connector turret 4 near the filter cavity 1.

[0024] Among them, the new connector turret 4 is a hollow cylinder. The new connector turret 4 is located on the outside of the filter cavity 1 to fix the pressing plate. The limiting notch 42 is located at the bottom of one side of the pressing plate. The new connector turret 4 and the connector are fixedly installed through the slot 41.

[0025] It should be noted that there are two limiting notches 42, which are symmetrically distributed on the left and right sides of the new connector turret 4. The slot 41 is parallel to the limiting notch 42, and the outer side of the bottom of the new connector turret 4 is provided with knurled teeth.

[0026] It should be noted that the new connector turret 4 is made of AL6061-T6 material, and its surface is treated with hard anodizing. AL6061-T6 is an aluminum alloy material. After T6 heat treatment, it has high strength and hardness and can withstand large loads. Its Brinell hardness can reach about 95-100, and its Rockwell hardness is about 12-15. This level of hardness makes it suitable for manufacturing parts that require a certain degree of wear resistance. It has good toughness and ductility, and its elongation can reach about 12%. This means that when subjected to external forces, it will not easily break, but can deform to a certain extent and absorb energy. This is very important for some structural components that need to withstand impact loads.

[0027] In this embodiment, one side of the transmission piece 3 is fixedly connected to the new connector turret 4, the bottom of the connector 2 is fixedly installed to the top of the new connector turret 4, the bottom of the connector 2 extends into the interior of the new connector turret 4, and the filter cavity 1 and the new connector turret 4 are pressed and fixed by a press.

[0028] The filter cavity 1 has a minimum cavity depth of 12mm. By setting a new connector turret 4, the connector 2 can be fixedly installed on the top of the new connector turret 4. By setting a slot 41, the distance between the connector and the filter cavity 1 can be shortened, thereby saving space. By setting a limiting notch 42, the new connector turret 4 can be pressed into the filter cavity 1, and the transmission piece 3 can be positioned. The structure is simple, the cost is low, and the space occupation is small.

[0029] The working principle of the above embodiments is as follows:

[0030] First, the staff uses a socket wrench to fasten the connector 2 to the top of the new connector turret 4. Then, the transmission piece 3 is welded to the new connector turret 4. At the same time, the transmission piece 3 is precisely positioned in the center of the slot 41 by PTFE. Then, the staff uses a press to press the new connector turret 4 into the filter cavity 1. At the same time, the new connector turret 4 is fixed by limiting notch 42.

[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
