Description
Technical field
The utility model relates to filter, particularly the ultra-thin line filter of one.
Background technology
Current line filter is widely used in various electronic product, and line filter version is varied, and a large amount of in producing be handwork.When present human resources are more in short supply, change the traditional structure of line filter, redesign line filter structure, make it standardization, reach the requirement of electronic product to EMC, and meet automated production, thus greatly enhance productivity, be very necessary and urgent.
As everyone knows, the version of current ultra-thin line filter is very many, and a lot of what adopt is directly coiling and go out pin on ferrite bead, because terminal pin is not easily fixed, is not easy to very much assembling, is not suitable for producing in batches.Design a kind of version of applicable automated production, complete coiling by automatic coil winding machine, and pins of products is fixed on the contact pin of frame special, carried out the production of line filter, greatly can improve the automaticity of transformer production like this.For reaching complete machine EMC requirement, coiling adopts the method for a point multistage coiling (traditionally general not segmentation), reduces device distributed capacitance, reaches the technical requirement of EMC.
Utility model content
The purpose of this utility model is to provide a kind of novel line filter structure.
The line filter that the utility model provides, comprise pedestal, dividing plate, magnet ring and coil, described coil winding is on magnet ring, and described pedestal is container cavity, described magnet ring is placed in container cavity inside, and described dividing plate is placed in magnet ring inside and is vertically fixed on the bottom of container cavity.
Particularly, described container cavity is circular container cavity, and the transverse diameter of described circular container cavity is greater than vertical footpath, and the corner of described container cavity is respectively arranged with extension, and described extension is fixed with contact pin.A kind of preferred scheme is: the transverse diameter scope of described container cavity is 23.2mm to 23.8mm, vertical footpath scope is 19.6mm to 20.0mm, the width range of described bar shaped extension block is 6.1mm to 6.3mm, the length range of described dividing plate is 9.25mm to 9.55mm, and the depth bounds of described container cavity is 7.6mm to 8.0mm.The concrete structure of container cavity is not the circle being necessary for regulation, can be other shape yet, and possessing under the condition holding magnet ring, other various structure is all fine, and the casting of general employing one-shot forming technique forms, and circle herein includes round and oval.
Particularly, described coil is wound on magnet ring with multistage coiling version, and the pin of coil is fixed on described contact pin, and a kind of scheme of comparative optimization adopts to divide the version of three sections to carry out coiling.Described contact pin is cylindrical rectangular, and the diameter of cylinder is 0.8mm, and the concrete length of contact pin designs according to demand.
Particularly, the outward flange of described container cavity is provided with extension block on transverse diameter direction, and described extension block is bar shaped extension block.A kind of preferred size is: described container cavity is 18.7mm to 19.3mm along the distance on transverse diameter direction between two extension central points, and the distance on vertical direction, footpath between two extension central points is 22.7mm to 23.3mm.
The beneficial effects of the utility model are: filter of the present utility model, pedestal is fixedly connected with dividing plate, superthin structure and the standardized production of product can be realized, magnet ring internal diameter is large, be applicable to automatic coil winding machine to produce, coil adopts a point multistage coiling form, can reduce the distributed capacitance of product, improve the frequency characteristic of product, reach complete machine EMC requirement.
Accompanying drawing explanation
Fig. 1 is pedestal and the diaphragm structure schematic diagram of embodiment.
Embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is further described, but this should be interpreted as that the scope of the above-mentioned theme of the utility model is only limitted to following example.Do not departing from the above-mentioned technological thought situation of the utility model, the various replacement made according to ordinary skill knowledge and customary means or change, all should be included in scope of the present utility model.
The utility model is for existing filter assembling inconvenience, dividing plate and pedestal need separately assemble, be not suitable for batch production, affect the problem of production efficiency, propose a kind of novel filter construction, comprise pedestal, dividing plate, magnet ring and coil, described coil winding is on magnet ring, described pedestal is container cavity, and described magnet ring is placed in container cavity inside, and described dividing plate is placed in magnet ring inside and is vertically fixed on the bottom of container cavity.
Embodiment
Line filter of the present utility model, include pedestal, dividing plate, magnet ring and coil, coil is wound on magnet ring with syllogic winding method, multistage coiling form can reduce the distributed capacitance of coil greatly, be conducive to suppressing interference, the magnet ring being wound with coil is fixed on base interior, pedestal adopts circular container cavity, the structure of pedestal and dividing plate as shown in Figure 1, possessing under the condition holding magnet ring, also other can be adopted to have the structure of accommodation function, such as square or polygonized structure, because the shape of coil is close to circle, therefore container cavity adopts circular best, and in order to mate with coil shape, the transverse diameter of container cavity will slightly be longer than vertical footpath.Four angles of container cavity are provided with extension, extension and container cavity are integral type structure, produce container cavity process in can one-shot forming obtain, the back side of four extensions is all provided with contact pin, can see when the back side is and uses with filter that face of coil for front as a reference.After coiling, the end of a thread of coil to be wrapped on contact pin and to weld, and sufficient space is left in lower end and the container cavity bottom surface of extension, can not exceed container cavity bottom surface after kinking.The outward flange of container cavity is provided with extension block on transverse diameter direction, and described extension block is bar shaped extension block, and the effect of bar shaped extension block is fixing plug pin.The transverse diameter of container cavity is 23.2mm to 23.8mm, and vertical footpath is 19.6mm to 20.0mm, and the width of described bar shaped extension block is 6.1mm to 6.3mm, and the length of described dividing plate is 9.25mm to 9.55mm, and the degree of depth of described container cavity is 7.6mm to 8.0mm.Container cavity is 18.7mm to 19.3mm along the distance on transverse diameter direction between two extension central points, and the distance on vertical direction, footpath between two extension central points is 22.7mm to 23.3cm.Contact pin is cylindrical rectangular, and the diameter of cylinder is 0.8mm.Above sized data can adjust accordingly according to concrete environment for use, originally exemplifies out concrete sized data and is only used to help reader to understand the technical solution of the utility model better, not in order to limit the protection range of the application.
