Member and structure for fixing core

Abstract

The present invention provides atechnology for reducing sizes, weight and even cost of a reactor by simplifying the core fixing structure of the reactor. A reactor (10) is provided with a case (101) for storing a core (109) and a coil (105). A core fixing member fixes the core (109) in the case (101). The core fixing member is constituted by integrally forming a first spring section (S1), which urges the side surface of the core (109) in the horizontal direction, with a second spring section (S2), which urges the upper surface of the core (109) in the vertical direction. Furthermore, a stopper section (ST), which regulates removal of the core (109) from the inside of the case (101), is integrally formed on a boundary to the second spring section (S2), through a cut (105) to cover a part of the upper surface of the core (109).

Description

technical field [0001] The present invention relates to a fixing member and its structure for fixing an electronic component in a housing, and particularly relates to a fixing member and its structure for fixing a magnetic core of a reactor in a housing with a spring member. Background technique [0002] Generally, a reactor has a winding and a magnetic core as a magnetic body, and obtains impedance by winding the winding around the magnetic core to form a coil. In the prior art, reactors are used in booster circuits, conversion circuits, active filter circuits, etc., and the reactors mostly adopt the following structure: the magnetic core and the coil wound on the magnetic core are combined with other insulating components It is housed in a case made of metal or the like (for example, refer to Patent Document 1). [0003] figure 1 It is a figure which shows the magnetic core fixing part in the said conventional reactor, (1) is its top view, (b) is its side view. That is,...

AI Technical Summary

Problems solved by technology

[0008] In the above-mentioned conventional magnetic core fixing structure, the magnetic core is fixed by a plurality of fixing parts, so the arrangement of the parts and the fixing method are complicated, and the space efficiency is deteriorated

As a result, the miniaturization and weight reduction of the reactor becomes difficult, and the cost also increases.

In addition, the movement (vibration) in the vertical direction of the magnetic core is absorbed by the rubber bearing, but the reliability of the rubber product is not good, and the function cannot be fully exerted

In the past, electronic components such as reactors have been processed to reduce waste as much as possible and reduce costs. However, the magnetic core fixing parts of reactors are very important parts from the viewpoint of vibration conditions and shock safety, but they are A structural component where cost reduction is difficult
