Technology Field

The invention relates to an inductor, in particular to a winding inductance coil component and a manufacturing method thereof.

技术领域

本发明涉及电感器,特别是涉及一种绕线电感线圈部件及其制作方法。深圳英语翻译

 

Background Technology

In recent years, while the winding inductance coil component needs to be miniaturized, more attention is paid to the manufacture cost and the use reliability of the product, and the product is required to maintain the use performance and prevent substantial degradation under the conditions of severe change of the temperature as well as external strong impact. Known to various winding inductance coil components, among the types, Patent Document 1: Publication No. CN 1637964A discloses a coil existing in a bobbin part of a drum-type magnetic core, and magnetic powder package resin with characteristic of special solidification is arranged around the coil; besides, Patent Document 2: Publication No. CN 101004967A discloses a product structure that magnetic resin is used to cover the drum-type magnetic core and a terminal component is arranged on the bottom of the coil part..

背景技术

近年来,要求绕线电感线圈部件小型化的同时,更加注重产品制作成本及使用可靠性,要求产品在温度剧烈变化及外部强力冲击的情况下,仍能保持产品使用性能而不出现大幅度劣化。已知多种类型的绕线电感线圈部件,在这些类型中,专利文献1:公开号CN 1637964A 公开了在鼓型磁芯的线轴部存在线圈,在该线圈周围配置有具有特殊固化特性的磁性粉封装树脂;另外,专利文献2:公开号CN 101004967A 公开了用磁性树脂覆盖鼓型磁芯,在线圈部件底部安装端子部件的产品结构。

 

As disclosed in Patent Document 1, the drum-type magnetic core is filled with package resin containing the magnetic powder, the package resin is in a state of rubber after solidification, because resin plays a weaker gluing role between the magnetic core, the upper magnetic core blade, the lower magnetic core blade and the internal winding in the state of rubber, the problems of electrical offset and physical impact resistance can easily occur when the product is severely impacted externally.

专利文献1 所公开构成中在鼓型磁芯的填充含有磁性粉的封装树脂,其固化后为橡胶状态,由于橡胶状态下树脂对磁芯、上下磁芯叶片、内部绕线之间的粘结作用较弱,故产品在外围剧烈冲击波动下,易出现电性偏移及耐物理冲击性能降低广州英语翻译
