But, the pin of the base bottom of known coil adopts the design of plug-in type, can't be welded on the circuit board with the surface adhesion technology, its range of application is restricted, and known enamel-cover line end all needs drawing to outside, be welded in the pin of base bottom behind the wire casing of pile warp pedestal side, make enamelled wire comparatively bother with the operation that is connected of pin.

Main purpose of the present utility model, be to provide a kind of improvement structure of fixed pedestal of magnetic bobbin core, it is the design of the pin of pedestal both sides being adopted welded type, so that utilize the surface adhering technology to be welded on the circuit board, make its range of application more extensive, and on pedestal, be provided with line hole and wire casing, can be convenient to this enamel-cover line end and directly pass through this iron core inside, by wearing the pin that cable-through hole and wire casing are fixedly welded on this pedestal, it is comparatively easily simple to make that enamelled wire is connected operation with pin, to promote speed of production, reduce labour cost, effectively reduce production costs.

In order to reach above-mentioned purpose, the utility model provides a kind of improvement structure of fixed pedestal of magnetic bobbin core, it mainly is to be provided with a plurality of lines hole in this pedestal, this line hole is to run through this pedestal top and bottom, this coil bottom is provided with a plurality of wire casings, this wire casing is connected with this line hole, this enamel-cover line end is to run through this line hole, the wire casing of this base bottom of pile warp, be fixed in the pin of this pedestal again, so that the pin of pedestal both sides can be fixed on the circuit board by welding manner, and this enamel-cover line end can directly pass through this iron core inside, by wearing the pin that cable-through hole and wire casing are fixedly welded on this pedestal, make enamelled wire and pin to be connected operation comparatively easily simple.

In order to further specify feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing.Yet accompanying drawing only provides reference and explanation usefulness, is not to be used for the utility model is limited.

Fig. 1 is the utility model three-dimensional exploded view;

Fig. 2 is a three-dimensional combination figure of the present utility model;

Fig. 3 is a front elevation of the present utility model;

Fig. 4 is the three-dimensional combination figure of another angle of the present utility model.

As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, the utility model is a kind of improvement structure of fixed pedestal of magnetic bobbin core, this coil 10 is made up of a

pedestal

11 and 12 of iron cores, this pedestal 11 is that insulation materials such as plastic cement or chock are made, this pedestal 11 is provided with a plurality of line holes 13 that are moon shape, this pedestal 11 napexes and bottom is run through in this line hole 13, this line hole 13 is corresponding with these coil 10 internal diameters, be provided with most wire casings 17 in addition in these coil 10 bottoms, this wire casing 17 is connected with this line hole 13, this wire casing 17 is to extend to this pedestal 11 both sides by line hole 13, the dual-side of this pedestal 11 is fixed with the pin 14 that a plurality of conductors are made, this pin 14 can be welded on the circuit board, and these pedestal 11 end face centre convex with a reference column 15, and this reference column 15 has and the corresponding suitable height of this iron core 12 width, and these reference column 15 external diameters are little than these iron core 12 hollow space internal diameters, this reference column 15 can have centre bore, is hollow form, convexes with a plurality of reference columns 18 at four jiaos of places of these pedestal 11 end faces in addition.

Unshakable in one's determination 12 are one circular, this iron core 12 places this pedestal 11 end faces with parastate, and make the sheathed reference column 15 that is configured in these pedestal 11 end faces of these iron core 12 hollow spaces, and twine the required number of turns on these iron core 12 surfaces with suitable envelope curve 16, and can borrow these enamelled wire 16 ends to run through this line hole 13, be connected and fixed on the pin 14 of this pedestal 11 behind the wire casing 17 of these pedestal 11 bottoms of pile warp, with should iron core 12 secure bond in these pedestal 11 end faces, this reference column 18 that is positioned at four jiaos of pedestal 11 end faces can provide positioning action, prevents 12 displacements unshakable in one's determination; Form a loop construction with this.
