Abstract

本实用新型涉及一种工字型电感器。它有一根磁芯(2),磁芯外绕有线圈(3)由接线柱(1)引出,其特征在于所述的磁芯两端各有圆磁片(2-1)、(2-1),其截面为一体的工字型。有了工字型线槽,既简化了绕线工艺,又提高了磁芯与线圈的耦合,可以节约铜材的使用,在相同电感量中是一种体积最小的电感器。

Description

工字型电感器
                         技术领域
本实用新型涉及一种工字型电感器。
                         背景技术
现有的棒式电感器，有一根磁芯，磁芯外绕有线圈，由接线柱引出。此电感器有如下不足：一是在磁芯上绕规整线圈的工艺要求较高；二是外层线圈与磁芯的耦合较弱，使电感量减小，为了达到同样电感必须增加线圈匝数，即增加铜线用量。
                         发明内容
本实用新型的工字型电感器，有一根磁芯，磁芯外绕有线由接线柱引出，其特征在于所述的磁芯两端各有圆磁片，其截面为一体工字型。有了工字型线槽，既简化了绕线工艺，又提高了磁芯与线圈的耦合，可以节约铜材的使用，在相同电感量中是一种体积最小的电感器。
                         附图说明
图1是本实用新型示意图。
                       具体实施方式
下面结合实施例和附图对本实用新型作进一步描述。
见图1，本例的电感器，有一根磁芯2，磁芯一般采用DR6～DR14，本例为DR10×12mm；磁芯2两端各有圆磁片2-1、2-2，成一体的工字截面。磁芯的工字槽绕有线圈3，线圈一般采用φ0.15～0.55mm的漆包线绕制，通常绕49-395TS，本例用φ0.29mm的漆包线绕225TS，由接线柱1引出。本例产品的电感量为2.0mH。工字型磁芯外套有塑料护套4，以提高对裸露磁芯的保护，当工作电压较高时，可提高产品的安全系数。

Claims (2)

1、一种工字型电感器，有一根磁芯(2)，磁芯外绕有线圈(3)由接线柱(1)引出，其特征在于所述的磁芯两端各有圆磁片(2-1)、(2-2)，其截面为一体的工字型。
2、根据权利要求1所述的气隙电感器，其特征在于所述的线圈外套有护套(4)。
