Arc-proof structure of noise filter

Abstract

The invention relates to an anti-arc structure with foreign-save filter, which comprises annular magnetic corn formed by magnetic material; two windings whose two ends are connected to power source and electric device; and the insulated line axle at the surface of magnetic corn, to avoid generating electric arc between winding and magnetic corn. The inventive structure can avoid generating arc between magnetic corn and winding.

Description

technical field [0001] The invention relates to a clutter filter, in particular to an anti-arc structure of the clutter filter which can prevent electric arcs between the magnetic core and the coil of the clutter filter by improving the internal structure of the clutter filter. Background technique [0002] Generally, a noise filter (noise filter) is to attenuate the electromagnetic wave clutter transmitted to the electronic equipment, and prevent the operation error and failure of the electronic equipment caused by the clutter. [0003] In particular, due to the use of various electronic devices recently, the density of electromagnetic waves in the surrounding environment is gradually increasing. Therefore, electronic devices in an electromagnetic wave environment that negatively affects cannot function normally as originally intended. [0004] The clutter filter is set on the clutter source or the affected electronic equipment to prevent the electronic equipment from malfu...

Problems solved by technology

[0011] However, the noise filter of the conventional technology has the following problem: In order to prevent mutual conduction between the magnetic core 6 and the coil 8, the surface of the coil 8 is coated with an insulating film 9, but when the coil 8 is wound, the insulating film 9 may Damage occurs, or when coating the magnetic core 6, the insulating film 9 may not be completely coated, resulting in damage to the insulation state between the magnetic core 6 and the coil 8, causing the problem of arcing (arc)

[0016] In addition, the baffle 10 has a structure simply bonded on the inner periphery of the baffle 10 by an adhesive 12; since the durability of the baffle 10 is low, it is easy to drop

That is, when there is an external shock or is applied to a device with large vibration, the baffle plate 10 will be detached from the magnetic core 6 due to the decrease in the adhesive force of the adhesive 12, and the performance of the noise filter 1 will be reduced.
