Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0036] Combined inductors, such as Figure 1 to Figure 10 As shown, it includes a drum-shaped magnetic core 1 and a magnetic sleeve 2 for shielding magnetic flux leakage. The drum-shaped magnetic core 1 is wound to form a coil winding 3; the outer periphery of the drum-shaped magnetic core 1 is also nested and fixed without using mold positioning and The part adopts epoxy resin to fix the connection, and is used to integrally position the drum-shaped magnetic ...

Abstract

The invention provides a combined inductor, and the inductor comprises a drum-shaped magnetic core and a magnetic sleeve used for shielding magnetic flux leakage; a multifunctional isolation hood which does not need to be positioned by a mold, is locally and fixedly connected by epoxy resin and is used for integrally positioning the drum-shaped magnetic core and the coil winding and self-tensioning, clamping and fixing the drum-shaped magnetic core and the coil winding in the center of the magnetic sleeve after being inserted is further nested and fixed at the periphery of the drum-shaped magnetic core; the multifunctional isolation hood is composed of a pair of symmetrically-arranged bottom metal terminal sheets and an isolation cylinder, the bottom end of a drum-shaped magnetic core is bonded and fixed to the centers of the pair of symmetrically-arranged bottom metal terminal sheets through epoxy resin, and a coil winding is wound on the drum-shaped magnetic core; the isolation cylinder is inserted into the magnetic core and the coil winding, and the outer edge of the top end of the isolation cylinder is clamped and connected to the inner side edge of the magnetic sleeve; the inductor is simple in structure, convenient to mount and process, convenient to position and fix, high in coplanarity and capable of effectively improving the production efficiency and the automatic production degree, and die positioning and curing processes after epoxy resin sealing in the prior art are omitted.

Description

【Technical field】 [0001] The invention relates to inductance technology, in particular to combined inductors. 【Background technique】 [0002] At present, with the development of computers, servers, telecommunication systems and other electronic products in the direction of miniaturization and low power consumption, electronic components are developing in the direction of small size, high efficiency, surface mount mounting, low surface mounting height, low weight, and low electromagnetic interference. , it is required that the power supply must also be small, thin and light, making the terminal products more and more miniaturized and ultra-thin, which puts forward higher requirements for the further miniaturization of components, and the size of the ferrite core The requirements are getting higher and higher. This type of equipment requires power conversion devices such as ultra-small, ultra-high-precision DC-DC converters, filter inductors, and signal amplification power ind...
