Combined type filter inductor

Abstract

The invention discloses a combined type filter inductor. The combined type filter inductor comprises a plurality of magnetic cores, wherein two ends of each magnetic core are fixedly connected with afirst plate and a second plate respectively; an electromagnetic wire is wound on the outer side of each magnetic core; a first binding post is fixedly installed at the bottom of one side of each firstplate; a second binding post is fixedly installed at the bottom of one side of each second plate; one end of each electromagnetic wire is electrically connected with the corresponding first binding post, and the other end of each electromagnetic wire is electrically connected with the corresponding second binding post; a wiring groove adaptive with each first binding post is formed in one end ofthe corresponding second binding post; one end of each first binding post extends to the interior of the corresponding wiring groove and is movably connected with the corresponding wiring groove; a first groove is formed in one side of the top of each first plate; and a clamping plate is movably installed inside each first groove. The combined type filter inductor is reasonable in design and highin practicability, a plurality of inductors can be combined together according to actual requirements by a user, and the combined type filter inductor is stable in connection and convenient to use.

Description

technical field [0001] The invention relates to the technical field of filter inductors, in particular to a combined filter inductor. Background technique [0002] The characteristic of the filter inductor is to block high frequency and pass low frequency, that is to say, it acts as a filter, so that the ripple voltage in the entire electronic circuit is reduced to meet the higher requirements of digital equipment for system stability. For example, the patent document with application number 201820013974.7 discloses a filter inductor, including a magnetic bar and two winding brackets. The winding bracket is composed of a socket and a winding splint. Between the splints, magnet wires are wound on the outside of the magnetic rod, and the magnet wires have wire ends A and B; a shielding sheet is connected between the winding splints of the two winding brackets, and the winding splints of the two winding brackets There is an encapsulation shell sealed between the two sockets, a...

Problems solved by technology

[0003] However, most of the existing filter inductors are used as a single inductor and do not have a combination function. It is inconvenient to combine multiple inductors according to actual needs during use. Therefore, we propose a combined filter inductor to solve the above problems.
