Description

一种功率型电感
技术领域
本实用新型涉及电感技术领域，尤其是指一种功率型电感。 
背景技术
电感器(Inductor)是能够把电能转化为磁能而存储起来的元件。电感器的结构类似于变压器，但只有一个绕组。电感器具有一定的电感，它只阻止电流的变化。如果电感器在没有电流通过的状态下，电路接通时它将试图阻止电流流过它；如果电感器在有电流通过的状态下，电路断开时它将试图维持电流不变。电感器又称扼流器、电抗器、动态电抗器。现有技术中，作为功率电感，通常采用具有绕设于磁芯上的线圈，然后再包覆在一基体内的封闭式电感器，该类电感器在通电时容易达到磁饱和状态，具有较大的功率损耗，并因此增大了电感磁芯的损耗。 
发明内容
本实用新型的目的在于提供一种结构紧凑、功率损耗小的功率型电感。 
为实现上述目的，本实用新型所提供的技术方案为：一种功率型电感，它包括有磁芯以及绕卷在磁芯上的线圈；线圈外侧包覆有塑封层，磁芯由一体成型的主体及端盖构成，端盖位于主体两端，且端盖两端为对称的弧状构成，弧面中心设有U形的导线槽；磁芯外侧设有外壳，外壳的其中一组对角设有倒角；外壳上设有与导线槽相配合的扣罩；线圈的引脚穿过导线槽后由外壳底部伸出。 
所述的扣罩为两个，分别位于外壳两端。 
本实用新型的结构具有较理想的感值并可有效减小磁芯的损耗，且结构简单、组装方便。 
附图说明
图1为本实用新型的磁芯结构示意图。 
图2为本实用新型的整体结构示意图。 
具体实施方式
下面结合所有附图对本实用新型作进一步说明，本实用新型的较佳实施例为：参见附图1和附图2，本实施例所述的功率型电感包括有磁芯1以及绕卷在磁芯1上的线圈2；线圈2外侧包覆有塑封层3，磁芯1由一体成型的主体及端盖构成，端盖位于主体两端，且端盖两端为对称的弧状构成，弧面中心设有U形的导线槽4；磁芯1外侧设有外壳5，外壳5的其中一组对角设有倒角；外壳5上设有与导线槽4相配合的扣罩6；线圈2的引脚7穿过导线槽4后由外壳5底部伸出。扣罩6为两个，分别位于外壳5两端。上述结构具有较理想的感值并可有效减小磁芯的损耗，且结构简单、组装方便。
