Inductor, automobile and preparation method of inductor

Abstract

The invention discloses an inductor, an automobile and a preparation method of the inductor, and particularly relates to the technical field of electronic semiconductors. The inductor comprises a cover plate, a magnetic core, two insulators, conductive terminals and a coil, the insulators are located at the two ends of the magnetic core respectively, and at least one conductive terminal is clamped between the magnetic core and each insulator; the conductive terminals extend out of the surface of the insulator, and the extending parts are protruding parts of the conductive terminals; the coil is wound on the magnetic core, and the wire end of the coil extends towards one end of the magnetic core and is connected to the protruding part of the conductive terminal at the corresponding end; and the wire tail of the coil extends towards the other end of the magnetic core and is connected to the protruding part of the conductive terminal at the corresponding end. The protruding parts of the conductive terminals ares connected with the wire head and the wire tail of the coil respectively, so that the outgoing line of the coil is not directly connected with the welding part, the situations that an enameled wire is not removed completely and the connection between the outgoing line of the coil and the welding part is unstable due to the use of a thermocompression welding process are avoided, furthermore, the connection strength of the inductance element is stable, and the working performance of the inductance element is ensured.

Description

technical field [0001] The present application relates to the technical field of electronic semiconductors, and in particular to an inductor, an automobile and a method for manufacturing the inductor. Background technique [0002] like figure 1 As shown, it is an inductance element used in the prior art. The inductance coil wire head 10 of the inductance element is connected to the metallized electrode 20 of the magnetic core by thermocompression welding. The film is not easy to remove cleanly, and the surface cleanliness of the magnetic core metallized electrode 20 is also difficult to ensure (for example, the enameled wire paint film remains), and the electrode surface is not easy to clean and the copper wire paint film remains, resulting in solder joints formed by hot pressure welding The internal resistance increases; when the temperature of the solder joints increases, the solder joints are softened, thus resulting in a decrease in the connection strength between the i...
