Description

Technical Field

[0001] The present application relates to the field of antenna technology, and in particular to an integrated antenna connector and an antenna. Background Art

[0002] A signal base station, also known as a public mobile communication base station, is an interface device for mobile devices to access the Internet. It is also a form of radio station, which refers to a radio transceiver station that transmits information between mobile terminals through a mobile communication exchange center within a certain radio coverage area.

[0003] A signal base station generally includes devices such as antenna units, filters, and radio frequency remote units. Since each device needs to be produced separately and assembled after production, in order to assemble the devices into a complete signal base station, connector welding ports need to be reserved between the devices. For example, SMP (Symmetrical Multi-Processing) board quick connectors are used to connect the ports between the components.

[0004] However, with the rapid layout of 5G signal base stations, 5G communications have increasingly stringent requirements on base station antennas in signal base stations. Specifically, 5G signal base stations integrate large-scale antenna arrays and other devices. A large number of antenna arrays need to present a certain spatial layout and cannot be integrated on the same circuit board. Therefore, more connection ports need to be reserved for welding connectors for connecting other components. The connectors themselves are small in size, and the reserved welding ports are all at the millimeter level. During the welding process of a large number of ports, welding errors are inevitable, which will lead to installation errors in the subsequent installation of devices, or even failure to install normally, reducing the construction efficiency of signal stations. Summary of the Invention

[0005] The present application provides an integrated antenna connector and antenna to solve the problem in the prior art signal base station that the antenna array needs to reserve a port for welding the connector, thereby causing installation errors of various components due to the welding of the connector, resulting in reduced efficiency in signal base station construction.

[0026] The following embodiments are described in detail, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numbers in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following embodiments are not intended to represent all possible implementations consistent with the present application. They are merely examples of systems and methods consistent with certain aspects of the present application, as detailed in the claims.

[0027] See also Figure 1 , which is a schematic diagram of the overall structure of the integrated antenna connector provided in an embodiment of the present application. The integrated antenna connector provided in this application includes an outer conductor 2 and an inner core 3 located within the outer conductor 2. The outer conductor 2 is disposed on a side surface of the antenna board 1. The outer conductor 2 is made of a non-metallic material, such as plastic, and is integrally formed with the antenna board 1 using in-mold injection molding technology.

[0028] The outer surface of the outer conductor 2 is provided with a first metal layer 21, and the first metal layer 21 is connected to the ground layer 11 of the antenna board 1. The inner surface of the outer conductor 2 is provided with an impedance layer 22. The first metal layer 21 and the impedance layer 22 are processed on the outer conductor 2 using LDS technology or selective electroplating technology.

[0029] Among them, LDS (Laser Direct Structuring) is a 3D-MID (Three-dimensional molded interconnect device) production technology that specializes in laser processing, injection molding, and electroplating processes. Its principle is to give ordinary plastic components / circuit boards electrical interconnection functions, component support functions, and plastic shell support and protection functions, as well as shielding, antenna and other functions generated by the combination of mechanical entities and conductive patterns.

[0030] See also Figure 2 , is a schematic diagram of the transmission line structure of the integrated antenna connector provided in an embodiment of the present application. The inner core 3 passes through the antenna board 1 and connects to the transmission line 12 on the other side of the antenna board 1. The transmission line 12 is used to connect functional units on the antenna board 1, such as the feed unit.

[0031] In actual application, the outer conductor 2 of the integrated antenna connector is integrally formed with the antenna board 1, avoiding the need to reserve a large number of connector welding ports on the antenna board 1, thereby avoiding installation errors of subsequent devices due to welding errors, and avoiding the inability to install due to connector welding, thereby improving the construction efficiency of the signal station.

[0032] To facilitate the connection of the connector to other devices, see Figure 3 , is a schematic structural diagram of an overall cross-section of the integrated antenna connector provided in an embodiment of the present application. In some embodiments of the present application, the integrated antenna connector further includes a guide body 4 provided on the outer conductor 2; the guide body 4 is a trumpet-shaped structure with openings at both ends, and the end with the smaller opening is connected to the outer conductor 2. The smaller opening of the trumpet-shaped structure is the same size as the opening of the outer conductor 2. Due to the small opening of the outer conductor 2, there are inconveniences in connection during use, especially when there are a large number of connectors, and the device (the plug corresponding to the connector) needs to be accurately connected to the corresponding connector. In the embodiment of the present application, a trumpet-shaped guide body 4 is provided on the outer conductor 2, and the end with the smaller opening of the guide body 4 is connected to the outer conductor 2. Through the positioning and guiding function of the guide body 4, it is ensured that external devices can be more conveniently connected to the integrated connector.

[0033] Furthermore, the guide body 4 is made of the same material as the outer conductor 2 and is integrally formed with the outer conductor 2 using in-mold injection molding. A second metal layer 41 is provided on the outer side of the guide body 4, and the second metal layer 41 is connected to the first metal layer 21. The first metal layer 21 is formed using LDS technology or selective electroplating technology.

[0034] A non-metallic guide layer 42 is provided inside the guide body 4. Because the inside of the guide body 4 needs to provide positioning and guidance, there is a certain amount of friction between the guide layer 42 and the connector. To avoid significant wear on the connector or affecting its conductivity, the guide layer 42 is made of a non-metallic material with relatively low hardness.

[0035] Since the impedance layer 22 needs to cooperate with the first metal layer to achieve signal impedance to the inner core 3, the impedance layer 22 needs to meet certain impedance requirements. In the embodiment of the present application, the impedance of the impedance layer 22 is 50 ohms.

[0036] Furthermore, in some embodiments of the present application, the outer conductor 2 may be made of a metal material. When a metal material is used, the outer conductor 2 is integrally formed with the antenna board 1 through the ground layer 11, and a non-metallic layer is provided between the outer conductor 2 and the impedance layer 22 to prevent conductive connection between the first metal layer 21 and the impedance layer 22.

[0037] It can be seen from the above technical solution that the integrated antenna connector provided in the embodiment of the present application includes an outer conductor 2 and an inner core 3 inside the outer conductor 2; the outer conductor 2 is arranged on one side surface of the antenna board 1 and is integrally formed with the antenna board 1; the outer surface of the outer conductor 2 is provided with a first metal layer 21, and the first metal layer 21 is connected to the ground layer 11 of the antenna board 1, and the inner surface of the outer conductor 2 is provided with an impedance layer 22; the inner core 3 passes through the antenna board 1 and is connected to the transmission line 12 on the other side of the antenna board 1.

[0038] In actual application, the outer conductor 2 of the integrated antenna connector is integrally formed with the antenna board 1, avoiding the need to reserve a large number of connector welding ports, avoiding installation errors of subsequent devices due to welding errors, and avoiding the inability to install due to connector welding, thereby improving the construction efficiency of the signal station.

[0041] It should be noted that the integrated antenna connector can be used not only on antennas, but also in other devices in the base station that require reserved connector welding ports, such as filters. If used for connecting filters, the antenna board 1 can be changed into a filter conversion board.

[0042] See also Figure 4 , is a schematic diagram of the structure of one side of an antenna provided in an embodiment of the present application.

[0044] The antenna including the integrated connector provided in the embodiment of the present application avoids reserving ports for welding connectors during actual application, reduces installation errors caused by welding connectors, and thus improves the construction efficiency of signal stations.
