Embodiment Construction

[0031] Referring to Figures 1 to 4, there is shown a magnetic element 100 according to a first embodiment of the present invention. As shown in FIG. 1 , the magnetic element 100 roughly includes a coil support 1 , a coil 6 , an insulating spacer 3 and a pair of magnetic cores 2 . The magnetic core 2 is a magnetic core similar to an "E" shape, which can be made of manganese-zinc alloy. The coil support 1 is a conventional type of coil support, which preferably consists of a liquid crystal polymer (LCP) material. The coil holder 1 includes a main body and bases 4 at both ends thereof. In the body of the coil holder 1 there is provided an opening 14 which is sized to allow the middle arm of the E-shaped magnetic core 2 to be inserted thereinto. Several coil terminals 5 are provided on each substrate 4 , two coil terminals 5 are shown in the figure. The insulating spacers 3 are likewise preferably made of a liquid crystal polymer (LCP) material and have a thickness of, for exam...

Abstract

The invention relates to a magnetic element, which comprises winding support with terminal base; winding coiled on the winding support; insulated baffle plate with hollow open to cover the base via the winding support; and the magnetic corn inserted into the winding support, wherein said base has the first positioning part; the baffle plate has second positioning part; the first and second positioning part can form adhesive stuff part through to the magnetic corn via mounting winding support, magnetic corn and insulated baffle plate together; therefore, it only needs to fill stuff into stuff part, to fix winding support, magnetic corn and baffle plate together. The invention can reduce cost and simplify process.

Description

technical field [0001] The invention relates to a magnetic element, in particular to a magnetic element comprising a coil support, a coil, a magnetic core and an insulating spacer. Background technique [0002] Magnetic components are a basic component with a wide range of applications. In order to meet the needs of modern communication, computer, audio-visual equipment, and automotive electronic systems, it is hoped to provide miniaturized magnetic components with stable electrical characteristics at low cost. [0003] For example, Japanese Laid-Open Utility Model Publication Kokai Hei 7-29812 discloses a magnetic element. As shown in FIG. 13 , the magnetic element roughly includes a coil support 2 , a coil 4 , an insulating spacer assembly 6 and a pair of E-shaped magnetic cores 5 . The coil holder 2 includes a main body provided with a central through hole 2b, and a base 1 with terminals 3a at both ends thereof. The insulating spacer assembly 6 includes an insulating s...
