Embodiment Construction

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0025] In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the quantity of indic...

Abstract

The invention provides a large-power wire-wound plate type inductor. The large-power wire-wound plate type inductor comprises a magnetic core and a coil wound on the magnetic core; two mounting pins are arranged at the bottom surfaces of the magnetic core at interval, two ends of the coil are electrically connected with two mounting pins, and a ring slot is arranged around the magnetic core; the coil is wound on the magnetic core and arranged in the ring slot; the coil comprises two conductors; two conductors are wound on the magnetic core in parallel; two ends of each conductor are electrically connected each of two mounting pins. The ring slot is arranged around the magnetic core to hold the coil, thereby guaranteeing that the coil is stably arranged on the magnetic core, and the impactresistance of the manufactured inductor is improved; two conductors are wound on the magnetic core in parallel to form the coil, the DC resistance can be reduced, the current resistance is greatly improved under the same volume, and then the miniaturization and the large power are realized.

Description

technical field [0001] The invention belongs to the field of power inductors, and more specifically relates to a high-power wire-wound chip inductor. Background technique [0002] Chip inductors are also called surface mount inductors. High-power chip inductors generally refer to chip inductors with a current resistance above 1A. With the continuous development of electronic technology, electronic components are gradually developing in the direction of high frequency, miniaturization, and power. High-power chip inductors are designed to meet the needs of electronic equipment, especially the electromagnetic compatibility requirements of the power supply. interference. "Chip inductor" is the name of the classification of inductor structure. Chip inductors are divided from the manufacturing process. There are four main types of chip inductors, namely wire-wound, laminated, braided and film-type chip inductors. Among them, the wire-wound chip inductor is the miniaturization ...
