The inductance coil comprises a magnetic core and a copper wire, the copper wire is wound on the magnetic core in a spiral shape, hardware terminals are assembled at the two ends of the magnetic core, an upper end electrode and a lower end electrode are arranged on the two sides of each hardware terminal in the vertical direction respectively, and the two ends of the copper wire are fixedly connected with the upper end electrodes of the two hardware terminals respectively. The upper end of the hardware terminal is fixedly connected with a plane structure. According to the invention, the magnetic core and the hardware terminal are assembled, then the winding is carried out, two ends of the coil are respectively welded to the upper end electrode of the hardware terminal and the lower end electrode of the hardware terminal as product electrodes, and a single product is obtained after the upper plane structure is bonded, so that batch production is realized, the production efficiency is improved, the production cost is reduced, and the anti-falling and anti-vibration performance of the product is enhanced; meanwhile, the plane structure effectively protects the electrode and the copper wire, and the situation that the copper wire is artificially damaged is avoided.
Description
technical field [0001] The invention relates to an inductance coil and a manufacturing method thereof. Background technique [0002] Inductance coils are more and more widely used in automobile tire pressure monitoring systems, and there are more and more types of inductance coils appearing on the market. Commonly, magnetic core metallization is used as electrodes, and the mechanical reliability of products in this way is low; or through Molded by injection molding, this method has good mechanical reliability, but the process is complicated, the cost is high, and magnet cracks are prone to occur. Contents of the invention [0003] The purpose of the present invention is to provide an inductance coil and its manufacturing method, which solves the problems of low mechanical properties of the existing metallized magnetic core, high cost of the injection molded packaged magnetic core, and easy occurrence of magnet cracks. [0004] In order to achieve the above object, the pre...
