Inductor

Abstract

The invention relates to an inductor comprising an integral magnetic core, a coil, a magnetic core, a first electrode sheet and a second electrode sheet. The magnetic core includes a first end and a second end which are laterally separated, and a front end surface and a rear end surface which are longitudinally separated. The magnetic core is provided with a recess extending from the front end surface through the rear end surface and extending from the first end toward the second end but is separated from the second end; the magnetic core has upper and lower magnetic core portions separated bythe recess, and the upper and lower magnetic core portions have a gap on the first end of the magnetic core. The coil includes a winding portion and first and second electrode pins extending from both ends of the winding portion, the winding portion is sleeved around the outer periphery of the lower magnetic core portion, and the first electrode pin is located outside the recess and extends toward the first end along the lateral direction, and the second electrode pin being located outside the recess and extending along the lateral direction toward the second end. The first electrode sheet iscoupled to the first end of the magnetic core to connect to the first electrode pin. The second electrode sheet is coupled to the second end of the magnetic core to connect the first electrode pin.

Description

technical field [0001] The present invention relates to an inductor, especially an inductor suitable for being combined on a circuit board by surface mount technology (SMT). Background technique [0002] Due to the increasing demand for miniaturization of electronic equipment, inductors also need to be developed towards miniaturized components. At the same time, the packaging technology requirements for inductors mounted on circuit boards are also higher. The packaging technology of inductors is generally divided into dual in-line packaging (DIP) and surface mount technology (SMT). Among them, SMT packaging technology is suitable for mass production, reduces the demand for operators, and can reduce the area and layers required for circuit boards. Etc. [0003] Surface mount inductors generally include a magnetic core, a coil wound on the magnetic core, and two electrode pieces combined at the bottom of the magnetic core to be fixed on a circuit board. Although the structur...

Problems solved by technology

Although the structure of conventional inductors has achieved partial results in implementation, however, the assembly of conventional inductors still has troublesome and time-consuming problems, resulting in the inability to effectively reduce costs

Specifically, the magnetic core of a conventional inductor is generally composed of two separate magnetic core elements, and the assembly of the two magnetic core elements and the coil is cumbersome and time-consuming.
