Description
Technical field
This utility model relates to inductive technologies field, refers in particular to assembled common mode inductance.
Background technology
Common mode inductance is also common mode choke, is usually used in the Switching Power Supply of computer filtering the electromagnetic interference signal of common mode.In board designs, common mode inductance has also been the effect of EMI filtering, for the electromagnetic wave outside radiation-emitting suppressing HW High Way to produce.Existing inductance is all to use integral structure, and its die sinking difficulty is big, and cost is high.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that the assembled common mode inductance that a kind of compact conformation, using effect are good, die sinking difficulty is low.
For achieving the above object, technical scheme provided by the utility model is: assembled common mode inductance, it includes upper cover, lower cover, seat board, modular ring body, wherein, seat board two ends are provided with up-small and down-big trapezoidal jack, lower cap body is n shape, modular ring phosphor bodies is annular, the n shape main body of lower cover is through after ring in modular ring body, its two side vertical wall embeds in corresponding trapezoidal jack along modular ring body sidewall vertically downward, perpendicular wall both sides embed fixing by triangle fixed block, upper cover inserts from modular ring body top, modular ring body ring it is positioned at bottom upper cover after insertion, and be connected to form one by connecting plate bottom upper cover and between lower tops, some arc fins it are provided with in the axial direction on the external side face of modular ring.
Bottom described seat board, two ends are provided with to the wire casing being centrally recessed into.
Being equipped with, with upper tops, the link slot coordinated with connecting plate bottom described upper cover, link slot inner chamber both sides are provided with screens.
This utility model is after using such scheme; car coat type is used to assemble between all parts; without using metal fixing; use rib structures that modular ring body can be separated to form several regions; when preventing coiling, coil concentrates on local; compact conformation after this programme assembling, using effect is good, and die sinking difficulty is low.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is modular ring body structural representation of the present utility model.
Detailed description of the invention
nullBelow in conjunction with all accompanying drawings, the utility model is described in further detail，Preferred embodiment of the present utility model is: see accompanying drawing 1 and accompanying drawing 2，Assembled common mode inductance described in the present embodiment includes upper cover 1、Lower cover 2、Seat board 4、Modular ring body 5，Wherein，Seat board 4 two ends are provided with up-small and down-big trapezoidal jack 6，Bottom seat board 4, two ends are provided with to the wire casing 10 being centrally recessed into，Lower cover 2 main body is n shape，Modular ring body 5 main body is annular，After the n shape main body of lower cover 2 passes modular ring body 5 internal ring，Its two side vertical wall embeds in corresponding trapezoidal jack 6 vertically downward along modular ring body 5 sidewall，Perpendicular wall both sides embed fixing by triangle fixed block 7，Upper cover 1 inserts from modular ring body 5 top，Modular ring body 5 internal ring it is positioned at bottom upper cover 1 after insertion，And be connected to form one by connecting plate 8 bottom upper cover 1 and between lower cover 2 top，Bottom described upper cover 1 and upper cover 1 top is equipped with the link slot coordinated with connecting plate 8，Link slot inner chamber both sides are provided with screens 3，Some arc fins 9 it are provided with in the axial direction on modular ring body 5 outer peripheral face.Use car coat type to assemble between all parts of the present embodiment, it is not necessary to use metal fixing, use rib structures that modular ring body can be separated to form several regions; when preventing coiling, coil concentrates on local; compact conformation after the present embodiment assembling, using effect is good, and die sinking difficulty is low.
The embodiment of the above is only the preferred embodiment of this utility model, not limits practical range of the present utility model with this, therefore the change that all shapes according to this utility model, principle are made, all should contain in protection domain of the present utility model.
