Abstract
The utility model relates to a coil iron core, comprising an iron core body. The iron core body contains a straight plate body and a horizontal cylinder which protrudes from the central part of the right flank of the straight plate body towards right. The straight plate body and the horizontal cylinder form a horizontal T-shaped configuration, and the coil winds on the horizontal cylinder. The iron core body also contains a cover, which is positioned on the right flank of the iron core body. At least, the left surface and the top surface of the cover form a communicated open hollow part, and the horizontal cylinder and the coil is positioned in the open hollow part. The rectangular shape formed by assembling the iron core body and the cover can effectively improve the space availability. By the opposite movements or the dorsad movements of the iron core body and the cover, the interval between the iron core body and the cover can be adjusted, and therefore, the inductance or the impedance of the coil can be adjusted. In addition, due to the horizontal T-shaped configuration of the iron core body with an open end, the coils can be manufactured by a great number separately or in advance, and one end of the horizontal T-shaped iron core body is sheathed and assembled on the horizontal cylinder of the iron core body, and as a result, the production rate is improved and the deliverability is increased.
