Embodiment Construction

[0034] Such as Figure 1 to Figure 5 As shown, one embodiment of a wirewound inductor assembly includes a ferrite drum core and a wirewound coil. The drum-shaped magnetic core has an upper magnetic core blade 11, a lower magnetic core blade 12 and a cylindrical winding core portion 13 connecting the upper and lower magnetic core blades, and the winding coil 31 is wound on the winding core portion 13, and its two ends are electrically connected. Connected to the external connection electrode 22 on the lower core blade 12 . The wound inductance coil component also has a magnetic mixed material mixed with magnetic powder and glue. After the magnetic mixed material is cured, a glue curing part 4 between the upper and lower magnetic core blades is formed, which covers the upper and lower magnetic core blades. The winding coil is filled in the space between the upper and lower magnetic core blades 11, 12. Wherein, the weight ratio of magnetic powder to glue is not lower than 10:8....

Abstract

The invention discloses a coil element of a winding inductor, which comprises a magnetic core, a winding coil winding on the magnetic core and a gluewater solidifying part. The gluewater solidifying unit covers the winding coil and fills a gap between the winding coil and the magnetic core. The gluewater solidifying part is formed by solidifying a magnetic mixed material comprising the gluewater and magnetic powder. The weight ratio of the magnetic powder to the gluewater is no less than 10:8. The invention further discloses a method for manufacturing the coil element of a winding inductor. By adopting the invention, the coil structure is beneficial to being stabilized, the impact resistance of the magnetic core is improved, and the electrical property and the reliability of the product can not be degraded in a process of drastic external vibration.

Description

technical field [0001] The invention relates to an inductor, in particular to a wire-wound inductor coil component and a manufacturing method thereof. Background technique [0002] In recent years, while the miniaturization of wire wound inductor coil components is required, more attention is paid to the production cost and reliability of the product, and the product is required to maintain the performance of the product without significant deterioration in the case of drastic temperature changes and external strong impacts. . Various types of wire-wound inductance coil parts are known, among these types, Patent Document 1: Publication No. CN 1637964A discloses that there is a coil in the bobbin portion of the drum-shaped magnetic core, and magnetic powder having special curing properties is arranged around the coil. Encapsulating resin; In addition, Patent Document 2: Publication No. CN 101004967A discloses a product structure in which a drum-shaped magnetic core is covere...
