Abstract

The invention provides a multiple-inductor terminal comprising a magnetic core wound with a copper wire and a terminal, wherein the copper wire is connected with the terminal; the upper part of the outer end of the terminal is provided with a bulge; the lower bottom surface of the magnetic core is connected with the surface of the terminal; and the lower part of the magnetic core is provided with a surface which is jointed with the inner side of the bulge of the terminal. The multiple-inductor terminal has the characteristics of stable adhesion, high heat dissipation efficiency and no circuit board module restriction.

Description

technical field [0001] The present invention relates to a terminal for multiple inductors. Background technique [0002] Generally, inductors are components used in power conversion of TVs, radios, communication equipment, etc., to convert voltage or current into other energy, and to stabilize the current. [0003] As mentioned above, the basic structure of the inductor is an air-core coil (copper wires are twisted together in a spiral shape, and there is nothing inside), but compared with an air-core coil, the copper wire is wound on a magnetic core or an object solidified by iron powder, and the performance will be lower. Better; such a coil can also be formed into a pair by one or more. [0004] Usually, the inductor used on the circuit board is composed of a housing ring core and a drum core (drum core, also known as a drum core). Pillars, assemble the pillars from the bottom to the lower half of the side and the terminal (clip) together, and the magnetic core is place...
