摘要： Disclosed is an inductor without a gap spacer. The inductor includes a bobbin having at least one round of wire wound thereon to serve as a coil of the inductor, a first magnetic member coupled with the bobbin, and a second magnetic member having a first end and a second end, wherein the second magnetic member is inserted into the bobbin from the second end thereof and the first end has a protrusion for allowing the second magnetic member to be partially inserted into the bobbin, thereby forming a gap between these two magnetic members.

摘要： Disclosed is a method for adjusting the inductance of an inductor at least including a bobbin, a first magnetic member having a concavity on a side wall thereof, and a second magnetic member having a protrusion at a first end thereof for preventing the second magnetic member from being completely inserted into the bobbin so as to form a gap between the first and second magnetic members. The method includes the steps of selecting a reference piece with a suitable thickness to be disposed between the protrusion of the second magnetic member and the side wall of the first magnetic member with the concavity and closely attached to both of them t as said second magnetic member is inserted into said bobbin, and partially removing the second magnetic member from a second end thereof according to the thickness of the reference piece so as to obtain a predetermined inductance value. This method further includes a step of determining whether the inductance of the inductor is identical to the predetermined inductance value after the reference piece is disposed between the protrusion of the second magnetic member and the side wall of the first magnetic member with the concavity and the second magnetic member is partially inserted into the bobbin. If the inductance of the inductor is not identical to the predetermined inductance value the thickness of the reference piece can be changed to repeat the above-described steps until the predetermined inductance value is obtained.
