Description

The common-mode inductor of insulation shell is housed

Technical field

The utility model relates to a kind of common-mode inductor that insulation shell is housed, and belongs to technical field of electronic components.

Background technology

At present, domestic and international most of common-mode inductor is in order to there be better magnetic closed-loop path, the winding that general use high magnetic permeability magnet ring coiling two Same Name of Ends are contrary, to realize the clutter in filtering circuit, reduce electromagnetic conductive and radiated interference, directly draw after four stretching scolding tin of pin, then at the additional insulating tape parcel of product ontology surrounding, like this to realize the isolation of complete machine plug-in unit and other device.

There is following defect in above-mentioned conventional common mode inductor: 1, draw after four stretching scolding tin of pin, the more difficult location of slotting pcb board, is unfavorable for plug-in unit; 2, at the additional insulating tape parcel of product ontology surrounding, top does not have encapsulate, is difficult to whole product and other device are effectively isolated, and there is withstand voltage insulation hidden danger.

Utility model content

The purpose of this utility model is, provides a kind of common-mode inductor that insulation shell is housed, to solve above-mentioned technical problem.

For achieving the above object, the technical scheme that the utility model adopts is:

A common-mode inductor for insulation shell is housed, comprises magnet ring and be wrapped in a winding on magnet ring, No. two windings; It is characterized in that: also comprise insulation shell, described insulation shell adopts mould one-shot forming, and be provided with longitudinal front wire casing in the middle part of the inwall of its front side wall, the left and right sides of described front wire casing is respectively arranged with a pin, No. three pins; The inwall of the rear wall of described insulation shell is provided with longitudinal rear wire casing, the left and right sides of described rear wire casing is respectively arranged with No. two pins, No. four pins; Described magnet ring is arranged in the inner chamber of insulation shell, and bottom is fixed on insulation shell intracavity bottom by epoxide-resin glue; Two lead ends of a described winding are separately fixed on a pin, No. two pins; Two lead ends of described No. two windings are separately fixed on No. three pins, No. four pins.

Say further, the top of the left side wall of described insulation shell is provided with left plate, and the top of the right side wall of described insulation shell is provided with right plate.

Beneficial effect: compared with prior art, the utility model is equipped with the insulation shell of band four pins, draw the end of a thread and be separately fixed on four pins for four of common-mode inductor, it is succinct, convenient to produce, and slotting pcb board is also easily located, and, the periphery of product does not need to add bag insulating tape, just can be completely isolated with other components and parts by insulation shell, insulation property are better, and anti-electromagnetic interference capability is stronger.
