Abstract
A magnetic device, comprising a body and a coil disposed in the body, wherein a terminal part of the conductive wire forming the coil comprises a first portion and a second portion, wherein the first portion is exposed from the body for forming an electrode, wherein the second portion of the terminal part is deformed for increasing the distance between the terminal part of the conductive wire and the coil for preventing a short circuit.
Claims10
A magnetic device, comprising:
- a T-core. comprising a base and a pillar on the base;
- and
- a coil, formed by a conductive wire, wherein at least one portion of the pillar is disposed in a hollow space of the coil, wherein a first terminal part of the conductive wire comprises a first portion and a second portion, wherein the first portion of the first terminal part is exposed from the body for forming a first electrode of the magnetic device, and the second portion extends from a top portion of the coil to an endpoint of the first portion of the first terminal part, wherein a top surface of the base and a horizontal plan form an angle between 20 degree and 60 degree, wherein the first portion of the first terminal part of the conductive wire is placed on the top surface of the base.
A method to form a magnetic device, said method comprising:
- forming a U-core;
- disposing a coil in a U-core, wherein the coil is formed by a conductive wire, wherein a first terminal part of the conductive wire comprises a first portion and a second portion, wherein the first portion and the second portion of the first terminal part of the conductive wire forms an angle between 110 degree and 150 degree;
- disposing a T-core on the coil, wherein the T-core comprises a base and a pillar on the base with a through-opening formed on a corner of the base, wherein at least one portion of the first terminal part of the conductive wire is disposed in the through-opening;
- and
- pressing the T-core and the first portion of the first terminal part of the conductive wire for forming the magnetic device, wherein the base is located above the pillar when the T-core is pressed.
2 more elements
