Description

[Technical Field]

[0001] This utility model belongs to the field of antenna communication technology, and in particular relates to a 5G external antenna. [Background Technology]

[0002] Currently, an increasing number of electronic products utilize wireless communication technology to wirelessly transmit data, sound, and images, thereby forming wireless local area networks. Drones, as tools for aerial photography, are highly sought after by consumers. Many users, seeking an immersive experience of the drone's view, have opted to combine VR glasses with drones, controlling the drone via an external antenna.

[0003] In the prior art, for example, the antenna device and image transmission equipment disclosed in Chinese Patent Publication No. CN209747726U include a coaxial cable and an antenna assembly. The antenna assembly includes a housing, an antenna bracket, an LDS antenna on the antenna bracket, and a connector. One end of the coaxial cable exposed in the housing is inserted into the connector, and the corresponding end of the wire core is welded to the connector to realize the electrical connection between the coaxial cable and the connector. In this solution, one end of the coaxial cable and the connector are both located outside the housing. On the one hand, this will cause the overall size of the antenna device to be too long, which may affect the user's experience of wearing VR glasses. On the other hand, since one end of the coaxial cable and the connector are both located outside the housing, there is no waterproof effect.

[0004] To address the problems of the aforementioned solutions, Chinese Patent Publication No. CN117394021A discloses a miniaturized antenna and drone VR glasses. This solution eliminates the coaxial cable as the connection medium between the terminals and the circuit board, thus reducing the overall size of the antenna. Simultaneously, both the terminals and the circuit board are integrated inside the housing, providing a waterproof effect. Therefore, this solution achieves both waterproofing and minimizes the overall size of the antenna. However, this solution still has the following two problems:

[0005] (1) The circuit board has a rectangular sheet structure. The rectangular circuit board will occupy a large space, which will result in a limited reduction in the overall size of the antenna.

[0006] (2) A notch is provided at one end of the sheet-like circuit board. The center pin on the terminal is inserted into the notch to realize the electrical connection between the center pin and the circuit board. When the insertion is completed, the center line of the center pin coincides with the center line of the short side of the circuit board. The center pin is round and the notch is square. The round and square center pins are difficult to position, which will increase the installation difficulty between the center pin and the circuit board. Moreover, after the round and square center pins are positioned on the sheet-like circuit board, they are prone to displacement, which will lead to electrical failure.

[0007] Therefore, it is necessary to provide a 5G external antenna to solve the above-mentioned technical problems. [Utility Model Content]

[0008] The main purpose of this utility model is to provide a 5G external antenna that can shorten the overall length of the external antenna, improve the reliability of the external antenna, and also improve the waterproof effect.

[0009] This utility model achieves the above-mentioned objective through the following technical solution: a 5G external antenna, comprising a housing and a radiating module, a PIN pin, and a connector installed inside the housing. One end of the housing is provided with a plug interface. The connector is sleeved around the PIN pin and located at one end of the plug interface. The radiating module is located at the end furthest from the plug interface. The radiating module includes a feed terminal and a ground terminal at its left and right ends. The feed terminal is provided with a feed pin, and the ground terminal is provided with a ground pin. One end of the PIN pin is connected to the feed terminal and is used to contact the feed pin to achieve electrical conduction. One end of the connector is connected to the ground terminal and is used to contact the ground pin to achieve electrical conduction. When receiving or transmitting a signal, the other ends of both the PIN pin and the connector are plugged into a transceiver to achieve electrical conduction.

[0010] Furthermore, the radiation module includes an annular main body and a sub-support disposed inside the main body and fixedly connected to the main body. A power supply circuit is provided on the left side of the main body and the left side of the sub-support to form the power supply terminal. A grounding circuit is provided on the right side of the main body and the right side of the sub-support to form the grounding terminal. The power supply pin is located on the left side of the sub-support, and the grounding pin is located on the right side of the sub-support.

[0011] Furthermore, the sub-bracket is provided with a first mounting through hole for mounting the PIN pin, and the left end of the PIN pin is inserted into the first mounting through hole to contact the power supply pin to achieve electrical conduction.

[0012] Furthermore, the left end of the connector is fixed to the right side of the sub-bracket and contacts the grounding pin to achieve electrical conduction.

[0013] Furthermore, the connector has an internal clearance through-hole for the PIN pin to pass through.

[0014] Furthermore, the housing includes a first housing and a second housing, which are mated and fastened together to form a receiving space, in which the radiation module, the PIN pin, and the connector are all housed.

[0015] Furthermore, one end of the first housing is configured as a closed end and the other end is configured as a first opening;

[0016] One end of the second housing is configured as a second opening that mates with the first opening, and the other end is the insertion interface.

[0017] Furthermore, the radiation module is disposed inside the first housing, with the power supply end facing the closed end and the grounding end facing the first opening, and a protective pad is provided between the power supply end and the closed end.

[0018] Furthermore, the second opening is provided with an outwardly extending annular flange, and an annular groove is formed between the outer wall of the annular flange and the outer wall of the second housing. When the first housing and the second housing are mated and fastened, the annular flange extends into the interior of the first housing, and the inner wall of the first housing contacts and seals with the outer wall of the annular flange.

[0019] Furthermore, the interior of the second housing is provided with a second mounting through hole for mounting the connector, and the space between the outer wall of the connector and the wall of the second mounting through hole is filled with waterproof adhesive.

[0020] Compared with existing technologies, the advantages of this 5G external antenna are as follows:

[0021] (1) The radiation module includes a circular main body and a sub-support set inside the main body and fixedly connected to the main body. The power supply circuit and the grounding circuit are distributed on the circular main body and the sub-support. The radiation module is circular in shape, which can shorten the length of the radiation module to the greatest extent, thereby further shortening the overall length of the external antenna.

[0022] (2) The sub-bracket has a planar structure and is provided with a first mounting through hole for positioning and mounting the PIN pin. The left end of the PIN pin is interference-fitted with the first mounting through hole. This design can ensure the reliability of the connection between the PIN pin and the sub-bracket, prevent damage, and save maintenance costs. It can also ensure the stability of the contact between the PIN pin and the power supply pin, thereby ensuring the smooth reception and transmission of signals.

[0023] (3) The first and second housings are fixedly connected by ultrasonic technology, eliminating the need for buckle structures or screw fixing posts. The size and weight of the external antenna are further reduced, which is conducive to the miniaturization and lightweight design of the 5G external antenna. It also reduces the impact of metal screws and other components on the performance of the 5G external antenna. In addition, the ultrasonic connection structure is tightly integrated, which can achieve a tight seal between the first and second housings, thereby preventing moisture, dust and other substances from entering the containment space through the connection between the first and second housings. This effectively protects the radiation module, PIN pins and connectors, and prevents the performance of the radiation module, PIN pins and connectors from being affected.

[0024] (4) A viscous waterproof adhesive is filled between the outer wall of the connector and the wall of the second mounting through hole. On the one hand, the viscous waterproof adhesive can firmly stick the connector into the second mounting through hole, which can further ensure the reliability of the assembly between the connector and the second housing. On the other hand, the waterproof adhesive can prevent moisture, dust and other substances from entering the containment space through the connection between the connector and the second housing, which can effectively protect the radiation module, PIN pin and connector, and prevent the performance of the radiation module, PIN pin and connector from being affected.

Detailed Implementation Methods

[0031] Please refer to Figures 1-2This embodiment is a 5G external antenna 100, which is used to be plugged into a signal transceiver (not shown in the figure) for receiving or transmitting signals. The 5G external antenna 100 includes a housing 1 and a radiating module 2, a PIN pin 3 and a connector 4 installed inside the housing 1. One end of the housing 1 is provided with a plug interface 11. The connector 4 is sleeved on the outer periphery of the PIN pin 3 and is located at one end of the plug interface 11. The radiating module 2 is located at the end away from the plug interface 11. The radiating module 2 includes a feed end 21 and a ground end 22 at the left and right ends. The feed end 21 is provided with a feed pin and the ground end 22 is provided with a ground pin. One end of the PIN pin 3 is connected to the feed end 21 and is used to contact the feed pin to achieve electrical conduction. One end of the connector 4 is connected to the ground end 22 and is used to contact the ground pin to achieve electrical conduction. When receiving or transmitting signals, the other end of the PIN pin 3 and the connector 4 are plugged into the signal transceiver to achieve electrical conduction.

[0032] In this embodiment, the radiating module 2 includes a circular main body 23 and a sub-support 24 disposed inside the main body 23 and fixedly connected to it. Correspondingly, the sub-support 24 is circular and located in the middle inside the main body 23. A feeding circuit is provided on the left side of the main body 23 and the left side of the sub-support 24 to form a feeding terminal 21, and a grounding circuit is provided on the right side of the main body 23 and the right side of the sub-support 24 to form a grounding terminal 22. The feeding pin is located on the left side of the sub-support 24, and the grounding pin is located on the right side of the sub-support 24. The radiating module 2 is circular and includes feeding terminals 21 and grounding terminals 22 at both ends. The feeding circuit and grounding circuit are distributed on the main body 23 and the sub-support 24. The radiating module 2 is circular in shape, which can minimize the length of the radiating module 2, thereby further shortening the overall length of the external antenna.

[0033] In other embodiments, the main body 23 may be configured as a square ring structure, and the corresponding sub-support 24 may be configured as a square structure. In other embodiments, the main body 23 and the sub-support 24 may be configured as other shapes, which are not limited here.

[0034] The sub-support 24 has a planar structure and a first mounting through-hole 25 for mounting the PIN pin 3. The left end of the PIN pin 3 is inserted into the first mounting through-hole 25 and extends out of the left side of the sub-support 24 to contact the power supply pin, thus achieving electrical conduction. The left end of the PIN pin 3 and the first mounting through-hole 25 are interference-fitted, which ensures the reliability of the connection between the PIN pin 3 and the sub-support 24, making it less prone to damage and saving maintenance costs; it also ensures the stability of the contact between the PIN pin 3 and the power supply pin, thereby ensuring the smooth reception and transmission of signals.

[0035] The left end of connector 4 is fixed to the right side of sub-support 24 by laser direct forming (LDS) technology, and the right side of connector 4 contacts the grounding pin to achieve electrical conduction. Connector 4 is sleeved on the outer periphery of PIN pin 3, and the interior of connector 4 is provided with a clearance through hole 41 for PIN pin 3 to pass through.

[0036] In this embodiment, connector 4 is an SMA connector. The SMA connector is fixed to the sub-support 24 using laser direct forming (LDS) technology, which ensures the reliability of the connection between the SMA connector and the sub-support 24, making it less prone to damage and saving maintenance costs. It also ensures the stability of the contact between the SMA connector and the grounding pin, thereby ensuring the smooth transmission and reception of signals. The SMA connector is existing technology, and its structure will not be described in detail here.

[0037] In other embodiments, connector 4 may be an MMCX connector or an IPEX connector, or other types of connectors. Connector 4 may be configured in different types so that the 5G external antenna 100 can be adapted to different types of transceivers.

[0038] The housing 1 includes a first housing 12 and a second housing 13. The first housing 12 and the second housing 13 are mated together to form a receiving space 14, in which the radiation module 2, the PIN pin 3, and the connector 4 are all housed. One end of the first housing 12 is a closed end 121 and the other end is a first opening 122. One end of the second housing 13 is a second opening 131 that mates with the first opening 122, and the other end is a plug-in interface 11.

[0039] The radiation module 2 is disposed inside the first housing 12, with the power supply end 21 facing the closed end 121 and the grounding end 22 facing the first opening 122. Since the power supply end 21 faces the closed end 121, a protective pad (not shown in the figure) is provided between the power supply end 21 and the closed end 121 to prevent collisions. This protective pad (not shown in the figure) prevents the radiation module 2 from contacting the inner wall of the first housing 12; furthermore, it buffers external forces on the first housing 12, reducing the impact of external forces on the radiation module 2. This protective pad (not shown in the figure) can be a foam layer or other flexible material; no limitation is made here.

[0040] The second housing 13 has an outwardly extending annular flange 132 at the second opening 131. The height of the annular flange 132 is lower than the height of the outer wall of the second housing 13, so that an annular groove 133 is formed between the outer wall of the annular flange 132 and the outer wall of the second housing 13. When the first housing 12 and the second housing 13 are mated and fastened, the first opening 122 and the second opening 131 are mated and fastened in opposite directions. The annular flange 132 extends into the interior of the first opening 122 side of the first housing 12. The shell wall of the first housing 12 conforms to the annular groove 133, and the inner wall of the first housing 12 contacts and seals the outer wall of the annular flange 132. The outer wall of the first housing 12 is flush with the outer wall of the second housing 13. The inner wall of the first housing 12 is sealed to the outer wall of the annular flange 132 to prevent moisture, dust, etc. from entering the receiving space 14 through the contact point between the inner wall of the first housing 12 and the outer wall of the annular flange 132. This effectively protects the radiation module 2, PIN pin 3, and connector 4, and prevents their performance from being affected. The outer wall of the first housing 12 is flush with the outer wall of the second housing 13, which ensures the consistency of the left and right heights of the housing 1 and ensures the aesthetics of the 5G external antenna 100. After the first housing 12 and the second housing 13 are fastened together, ultrasonic welding is used to connect the first housing 12 and the second housing 13, thereby achieving a fixed connection between the first housing 12 and the second housing 13. The ultrasonic process for connecting the first housing 12 and the second housing 13 eliminates the need for snap-fit ​​structures or screw fixing posts, further reducing the size and weight. This is beneficial for the miniaturization and lightweight design of the 5G external antenna 100, and also reduces the impact of metal screws and other components on the performance of the 5G external antenna 100. Furthermore, the ultrasonic connection structure is tightly joined, enabling a tight seal between the first housing 12 and the second housing 13, thereby preventing moisture, dust, etc. from entering the housing space 14 through the connection between the first housing 12 and the second housing 13. This effectively protects the radiation module 2, PIN pin 3, and connector 4, preventing their performance from being affected.

[0041] The second housing 13 has a second mounting through hole 134 for mounting the connector 4. The connector 4 and the second mounting through hole 134 are conformally fitted to each other, which can ensure the reliability of the assembly between the connector 4 and the second housing 13. Waterproof adhesive (not shown in the figure) is filled between the outer wall of the connector 4 and the hole wall of the second mounting through hole 134. The waterproof adhesive is sticky. On the one hand, the adhesive can firmly stick the connector 4 to the second mounting through hole 134, which can further ensure the reliability of the assembly between the connector 4 and the second housing 13. On the other hand, the waterproof adhesive can prevent moisture, dust and other substances from entering the receiving space 14 through the connection between the connector 4 and the second housing 13, which can effectively protect the radiation module 2, PIN pin 3 and connector 4 and prevent the performance of the radiation module 2, PIN pin 3 and connector 4 from being affected.

[0042] In this embodiment, connector 4 is a female connector. The right end of the female connector is aligned with or retracted inside the second housing 13. The right end of the female connector forms a mating cavity for the male connector on the transceiver (not shown in the figure) to be inserted. The right end of the PIN pin 3 is retracted within the mating cavity of connector 4. When the 5G external antenna 100 is plugged into the transceiver (not shown in the figure), it can be ensured that connector 4 and PIN pin 3 will not be exposed in the second housing 13, further preventing moisture, dust, etc. from affecting the performance of PIN pin 3 and connector 4. In other embodiments, connector 4 can also be set as a male connector. There is no limitation here. It is only necessary to adjust the structure of the second housing 13 to adapt to different connectors 4 according to the actual situation.

[0043] When using the 5G external antenna 100 provided in this solution, first plug the 5G external antenna 100 into the signal transceiver (not shown in the figure). After powering on, the PIN pin 3 contacts the feed pin to achieve electrical conduction, and at the same time, the connector 4 contacts the ground pin to achieve electrical conduction. If it is necessary to receive the signal radiated by the signal base station (not shown in the figure), the changing current on the radiating module 2 will generate a radiation field and transmit the signal to the signal transceiver (not shown in the figure) through the PIN pin 3 and the connector 4. If it is necessary to transmit the signal through the signal transceiver (not shown in the figure), the signal is transmitted to the radiating module 2 through the PIN pin 3 and the connector 4 and then transmitted to the signal base station (not shown in the figure) to complete the signal transmission. Therefore, the 5G external antenna 100 of this solution can work with the signal transceiver (not shown in the figure) to complete the reception and transmission of signals.

[0044] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
