Triaxial receiving antenna and manufacturing method therefor

Abstract

The invention discloses a triaxial receiving antenna and a manufacturing method therefor. The triaxial receiving antenna comprises a magnetic core, three groups of wire coils wound around the magneticcore and a packaging body, wherein the three groups of wire coils are respectively wound around three wire winding parts of the magnetic core in an orthogonal manner, and wire ends of each group of wire coils are connected to corresponding electrodes of the magnetic core; after the magnetic core and the winding wire coils are packaged following winding of the three groups of wire coils, the packaging body is formed; the magnetic core and the wire coils are enabled to be completely positioned in the packaging body; a bottom part of the packaging body is provided with a plurality of electric conduction parts of which double faces are conductive, the electric conduction parts are the same as the electrodes on the magnetic core in terms of quantity, each electrode is connected with one conductive face of a corresponding conductive part, and the other conductive face of each conductive part is exposed from the packaging body. Via the method disclosed in the invention, the magnetic core onwhich the wire coils are wound is directly attached to a packaging substrate equipped with the conductive parts, single items are formed via cutting operation after overall packaging is conducted through use of glue, and the wire ends are connected with the conductive parts via the electrodes and are led beyond the packaging body.

Description

technical field [0001] The invention relates to the communication field, in particular to a three-axis receiving antenna and a manufacturing method thereof. Background technique [0002] Three-axis receiving antennas are more and more widely used in car keyless entry systems, and there are more and more types of three-axis receiving antennas appearing on the market. For example, the patent document with the application number of 201020281914.7 discloses a three-axis receiving antenna. Although the three-axis receiving antenna can meet the basic requirements of automobile smart keys, it has certain defects: the manufacturing process is complicated and the production efficiency is low; The wire leads are exposed outside, and the periphery is protected by a foam plastic sheet and a plastic shell, which has low reliability and cannot effectively protect the product. [0003] In addition, most customers often have different requirements for three-axis receiving antennas, and nee...

For example, the patent document with the application number of 201020281914.7 discloses a three-axis receiving antenna. Although the three-axis receiving antenna can meet the basic requirements of automobile smart keys, it has certain defects: the manufacturing process is complicated and the production efficiency is low; The wire leads are exposed outside, and the periphery is protected by foam plastic sheets and plastic shells, which has low reliability and cannot effectively protect the product

[0003] In addition, most customers often have different requirements for the three-axis receiving antenna, and need to match different pads. For the manufacturers of the three-axis receiving antenna, it is necessary to re-develop correspondingly, which increases repetitive work and cost input.
