Description

Technical Field

[0001] The utility model relates to the field of antennas and labels, and more specifically, to a DFN label with a built-in antenna. Background Art

[0002] The built-in antenna is a component used to receive and send wireless signals. The DFN tag is a specific type of electronic component. When producing the antenna, the DFN tag and the antenna need to be assembled in the circuit at the same time to facilitate the subsequent use of the antenna. However, during installation, the antenna needs to be connected and fixed with metal parts. Before that, the antenna needs to be pre-made with holes. At the same time, the operation is not convenient enough, which affects the assembly efficiency of the device.

[0003] Chinese patent application number: CN202222842462.0, provides a tag antenna that is easy to assemble. This solution uses a screw-type screw-on and screw-on method to quickly install and fix the antenna to be installed in the built-in frame through a buckling structure to complete the assembly of the antenna. The assembly of the antenna is more convenient. Compared with the traditional prefabricated hole operation, no hole is required to ensure the stability of the antenna, and further prevent the antenna from being damaged during the prefabricated hole process. At the same time, the rubber pad arranged on the lower surface of the pressure plate can be deformed under pressure to prevent the pressure plate from excessively squeezing the antenna and causing damage to the antenna. It can also further increase the friction between the pressure plate and the antenna to ensure the stable buckling effect of the antenna.

[0004] However, in actual use, there may be electromagnetic compatibility issues between the tag and the antenna. The antenna and the tag may affect each other's electromagnetic performance and may have a certain impact on each other's functions. Therefore, a DFN tag with a built-in antenna is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide a DFN tag with a built-in antenna, wherein the antenna assembly and the DFN tag assembly are connected by a connector, wherein the tag shielding cover is installed with a tag circuit board, the tag circuit board facilitates the circuit connection of the tag body, and facilitates the subsequent DFN tag assembly to provide information to the antenna assembly. The tag shielding cover can be made of metal material, and in subsequent use, it can prevent electromagnetic compatibility problems between the tag body and the antenna assembly, and can improve the stability of the performance between the tag body and the antenna assembly.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A DFN tag with a built-in antenna comprises an antenna assembly, a DFN tag assembly is installed on the top of the antenna assembly, and the DFN tag assembly is adapted to the antenna assembly; the DFN tag assembly comprises a tag shielding cover, the tag shielding cover is installed above the antenna assembly, a tag circuit board is installed inside the tag shielding cover, a tag body is installed on the top of the tag circuit board, the tag body is electrically connected to the tag circuit board, and a connector is installed at the bottom of the tag shielding cover, and the connector is connected to the antenna assembly;

[0008] The antenna assembly and the DFN tag assembly are connected through a connector, wherein the tag shielding cover is installed with a tag circuit board, which facilitates the circuit connection of the tag body and the subsequent DFN tag assembly to provide information to the antenna assembly. The tag shielding cover can be made of metal material, which can prevent electromagnetic compatibility problems between the tag body and the antenna assembly in subsequent use, and can improve the stability of the performance between the tag body and the antenna assembly.

[0019] (2) This solution facilitates the displacement of the movable plate by means of a tension spring, and when the movable plate is not pulled by an external force, the movable plate can be pulled back, so that the movable plate drives the spring and the anti-slip rubber head to be squeezed inward, and the spring facilitates the anti-slip rubber head to form a soft squeeze. When the card block is located in the base, the anti-slip rubber head squeezes the card block, restricting the position of the card block in the base, thereby connecting the welding block to the base, and connecting the antenna shielding cover to the label shielding cover. When the antenna shielding cover and the label shielding cover need to be separated later, the movable plate is pulled apart, so that the movable plate drives the spring and the anti-slip rubber head to move outward, so that the position of the card block is no longer restricted, and the antenna shielding cover can be separated from the label shielding cover.
