Description

Core with improved yield

This creation is a coil core, especially a core that increases the yield.

A common lan-transformer, or Ethernet Transformer, is used for signal processing or filtering noise. It is typically placed between the Ethernet chip and the (RJ45) connector, mainly for isolating the chip. And the connector to improve the quality and speed of the data signal transmission, thereby providing distortion-free signal transmission or suppression of radiation emission. Of course, network transformers can also be divided into inductive or capacitive network transformers.

In the network transformer, the main structure disclosed may include a common mode choke, a transformer (or auto transformer), an inductor and a capacitor (or a coupling capacitor), and the coil type thereof as described above. Components such as common mode filters and inductors (or transformers) are more commonly arranged as separate components/parts (ie, two-piece) and are electrically connected to the substrate or circuit board. Therefore, when the common mode filter and the inductor (or transformer) in the network transformer are two-piece components, it is not only time-consuming in the manufacturing process (for example, it takes at least twice as long to manufacture the core and the winding). And the two-piece component has the problem of high material cost.

Therefore, how to improve the above-mentioned problems, that is, the technical difficulties that the applicant of this case wants to solve.

In view of the use of the application, this creation aims to solve and improve the problems and defects of the application.

In order to achieve the above object, the present invention provides a magnetic core capable of improving yield, comprising: a magnetic core body having a first winding portion and a second winding portion, and the magnetic core A first flange and a second flange are respectively disposed on two sides of the body, and a third flange is disposed on the magnetic core body between the first flange and the second flange, and a bottom surface of the first flange a first end electrode and a second end electrode are disposed on the bottom surface of the second flange, and a third end electrode and a fourth end electrode are disposed on the bottom surface of the second flange, and a fifth end electrode is disposed on the bottom surface of the third flange And a sixth end electrode, a first groove is disposed on the first side of the third flange, and a second groove is disposed on the second side of the third flange.

Preferably, the first end electrode and the second end electrode are both disposed as a seventh end electrode, and the seventh end electrode is disposed on a bottom surface of the first flange.

Therefore, by the arrangement of the first groove and the second groove, the entanglement can make the winding (winding) winding on the magnetic core (including electrical connection to each terminal electrode), and the winding can be made. A portion of the (winding) is wound on the first groove or the second groove, the first groove or the second groove generating a support point or a fixed point for the winding (winding) to be wound (winding) The winding has a large elasticity and a large change, and it can control the winding direction of the winding (winding) (clockwise winding or counterclockwise winding), thereby achieving easy production and thus improving yield.

In order for your review board to have a clear understanding of the content of this work, please refer to the following examples with diagrams and symbols, please refer to it.

Referring to the first to third figures, the present invention provides a magnetic core which can improve the yield. Please refer to the first figure and the second figure first, which includes: a magnetic core body 1.

The core body 1 has a first winding portion 11 and a second winding portion 12, and a first flange (flange or frame) 13 and a first portion are respectively disposed on two sides of the core body 1. a second flange 15 is disposed on the core body 1 between the first flange 13 and the second flange 14. The first flange electrode 13 is provided with a first end electrode 2 And a second terminal electrode 3, a second terminal electrode 4 and a fourth terminal electrode 5 are disposed on the bottom surface of the second flange 14, and a fifth terminal electrode 6 is disposed on the bottom surface of the third flange 15 and A sixth end electrode 7 is disposed on the first side of the third flange 15 and a second recess 152 is disposed on the second side of the third flange 15. The bottom surface of the flange is such that each end electrode is mounted on the surface of the substrate or the circuit board by surface-mount technology (SMT).

Therefore, by the arrangement of the first groove 151 and the second groove 152, the present invention enables the winding (winding) to be wound on the magnetic core (including electrical connection to each terminal electrode).
