Embodiment 1

[0033] Embodiment 1: the multi-pole combined magnetic core with magnetic shielding, such as figure 1 As shown, it is composed of a top plate 1, a bottom plate 2, a frame 3, and several magnetic core posts 4. Two threading hole slots 5 are arranged on the bottom plate. The magnetic core posts 4 are split structures, and the frame 3 is also a split body. structure, the upper magnetic core column 41 and the upper frame 31 are integrated with the top plate 1, the lower magnetic core column 42 and the lower frame 32 are integrated with the bottom plate 2, and the upper magnetic core column 41, the upper frame 31 and the top plate 1 are formed. The magnetic core is installed symmetrically with the lower magnetic core composed of the lower magnetic core column 42, the lower frame 32 and the bottom plate 2, and the five magnetic core columns 4 are all arranged in the magnetic shielding cavity formed by the top plate 1, the bottom plate 2 and the frame 3, as Figure 9 shown.

Abstract

A multi-polar combined magnetic core with magnetic shielding function consists of a top board, a bottom board, a side frame and a plurality of magnetic core columns, and all the magnetic core columns are arranged in a magnetic shielding cavity which consists of the top board, the bottom board and the side frame. As a plurality of magnetic circuits are combined together, a separate assembly structure is adopted, the magnetic shielding cavity consists of the top board, the side frame and the bottom board, and all the magnetic core columns are arranged in the magnetic shielding cavity, the magnetic core with the combined structure can not only optimize the distribution of the magnetic circuits, reduce the size of an electronic component, expand the functions of the electronic component and meet the requirements of electronic devices on miniaturization and multiple functions, but also carry out the magnetic shielding on the electronic element, thus leading the electronic component to have the anti-electromagnetic interference ability and simultaneously greatly reducing the electromagnetic interference generated by the electronic component to the outside.

Description

Technical field: [0001] The invention relates to a multi-pole combined magnetic core used for installing multiple inductors, transformers or other electronic components. Background technique: [0002] With the rapid development of the electronics industry, high performance, miniaturization, and multi-function are the future development directions of electronic equipment. In order to achieve this goal, it is common practice for people to simply combine several electronic components and install them densely. In this way, Although the volume has been reduced, there is relatively large interference between the various components, and the assembly is complicated, the cost is high, and the performance is not ideal. If multiple components with different functions can be combined in the same multi-pole combined magnetic core with magnetic shielding, the assembly density of components can be improved, the size can be reduced, the cost can be greatly reduced, and excellent shielding e...
