Description

Technical Field

[0001] This utility model relates to the field of filter technology, and more specifically to an integrated structure of a port connector horn and cover plate. Background Technology

[0002] With the large-scale construction of 5G network base stations, each base station needs to install multiple filters that operate at 5G network frequencies. The filters are required to have high batch pass rates, simple processes, and low costs.

[0003] Chinese Patent Publication No. CN219959390U discloses a filter comprising: a housing having a functional cavity; a tuning cover plate covering the housing and sealing the functional cavity; a connector passing through one side of the housing and extending to the functional cavity, the end of the connector extending to the functional cavity having a threaded hole; a connecting rod disposed in the functional cavity and having an external thread structure at one end, the connecting rod being connected to the threaded hole through the external thread structure; a connecting piece disposed in the functional cavity and having one end connected to the end of the connecting rod away from the connector; a port copper wire disposed in the functional cavity and having one end connected to the end of the connecting piece away from the connecting rod; a resonator disposed in the functional cavity and connected to the end of the port copper wire away from the connecting piece; and a tuning screw passing through the tuning cover plate and extending to the port of the resonator.

[0004] However, this filter uses a method of riveting the connector to the functional cavity, which means that the height of the connector needs to be adjusted by adjusting the height of the first support member. This results in problems such as difficulty in adjustment and a small range of cavity depth, which need to be improved. Utility Model Content

[0005] In view of this, the purpose of this application is to provide an integrated structure of the port connector flare and cover plate, so as to increase the space below the connector and expand the range of cavity depth selection. The specific solution is as follows:

[0006] An integrated structure of a port connector horn and cover plate includes a cavity and a tuning cover plate that matches the cavity. The cavity has an inner cavity and a connector is disposed therein. The upper end of the connector is connected and fixed to the lower side of the tuning cover plate. A metal connecting rod is disposed at the bottom of the connector. The cavity has a socket that communicates with the inner cavity and allows the bottom of the metal connecting rod to be inserted.

[0007] Preferably, a PTFE sleeve is fitted to the bottom of the metal connecting rod, and the outer peripheral sidewall of the PTFE sleeve matches the inner diameter of the insertion cavity.

[0008] Preferably, the upper side of the tuning cover is provided with a flared opening, and the bottom of the flared opening is connected to the top of the connector.

[0009] Preferably, the tuning cover is fitted with a tuning screw, and the inner cavity is fitted with a resonator that matches the tuning screw vertically.

[0010] Preferably, an SMA connector is inserted into the outer side of the cavity.

[0011] As can be seen from the above solutions, this application provides an integrated structure of port connector flare and cover plate. This integrated structure of port connector flare and cover plate has the following beneficial effects: by setting the flare of the connector on the tuning cover plate, and riveting the connector core and medium to the outer shell on the tuning cover plate, the space below the connector is significantly increased, thereby achieving the purpose of increasing the cavity depth adjustment range.

[0015] To make the technical solution and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0016] like Figure 1 As shown, a port connector with an integrated horn and cover structure includes a cavity 1 and a tuning cover 2 that matches the cavity 1. A horn 21 is provided on the tuning cover 2, which is used to mate with a connector 6.

[0017] like Figure 1 , Figure 2As shown, an inner cavity 11 is provided within the cavity 1. The connector 6 is located within the inner cavity 11, and its upper end is fixedly connected to the lower side of the tuning cover 2. In this embodiment, the upper end of the connector 6 is fixedly connected to the lower side of the tuning cover 2 using a riveting connection, facilitating the installation, fixing, disassembly, and maintenance of the connector 6. Simultaneously, the bottom of the flared opening 21 communicates with the top of the connector 6. A metal connecting rod 7 is provided at the bottom of the connector 6, and a cavity 12 is provided in the cavity 1, communicating with the inner cavity 11 and allowing the bottom of the metal connecting rod 7 to be inserted. The cavity 12 allows for effective adjustment of the cavity depth range by adjusting the height of the connector 6.

[0018] It should be noted that a PTFE sleeve 8 is fitted onto the bottom of the metal connecting rod 7, and the outer peripheral sidewall of the PTFE sleeve 8 matches the inner diameter of the insertion cavity 12. Simultaneously, a tuning screw 3 is inserted into the tuning cover plate 2, and a resonator 5, corresponding to the upper and lower parts of the tuning screw 3, is inserted and fixed in the inner cavity 11. An SMA connector 64 is inserted into the outer side of the cavity 1.

[0019] In summary, this application provides an integrated structure of the port connector 6 horn 21 and cover plate. This integrated structure of the port connector 6 horn 21 and cover plate significantly increases the space below the connector 6 by setting the horn 21 of the connector 6 on the tuning cover plate 2 and riveting the inner core and medium of the connector 6 to the outer shell on the tuning cover plate 2, thereby achieving the purpose of increasing the cavity depth adjustment range.
