The secondary coil holder and the primary coil holder are respectively provided with a separate winding seat and a separate external pin, wherein a primary winding and a secondary winding are respectively wound on the winding seat, and are respectively connected with the corresponding external pins; since the winding seats of the secondary coil holder and the primary coil holder are mutually sleeved, and form separation, the primary-secondary coil holder has good separation effect, in addition, since the secondary coil holder and the primary coil holder are respectively provided with a winding seat and an external pin, the primary winding and the secondary winding of the transformer can self-form modules in the production, the assembly can be easily accomplished only by adopting a simple combination operation, thereby the transformer and the primary-secondary coil holder thereof have the advantages of both simplified process technology and reduced cost.

Description

Transformer and primary-secondary type coil holder thereof
Technical field
The utility model is about a kind of transformer, refers to especially a kind ofly have the primary-secondary type coil holder and be convenient to modular transformer.
Background technology
General high frequency transformer roughly comprises: coil holder (bobbin), iron core (core) and coil windings.As shown in Figure 7, it is a kind of traditional single-layer type coil holder 70, when these coil holders 70 of transformer adopting, adopt at coil holder 70 with wire rod (enamelled wire) and to mix around mode to constitute elementary winding and secondary winding respectively, particularly, first winding elementary (primary side) winding, and after finishing first class F insulation, then winding secondary (secondary side) winding is finished time class F insulation again.And between elementary winding and secondary winding, also certain quarantine measures must be arranged.
Must impose certain quarantine measures owing to aforementioned between elementary and secondary winding to mix the transformer that constitutes the primary and secondary winding around mode, not only making technology is complicated and manufacturing cost is higher relatively.
And for example shown in Figure 8, the another kind of coil holder that existing high frequency transformer often adopts, be called primary-secondary type coil holder 80, so-called primary-secondary type coil holder 80 comprises a sub-coil holder 81 and a bus-bar frame 82, has a rectangular box-like bobbin winder base 810 on this sub-coil holder 81, and set up separately in relative two ends and to draw pin 811 outside several, 812, this bobbin winder base 810 is for winding secondary winding (not shown), winding secondary winding season, one the end of a thread was fixed on sub-coil holder 81 1 ends earlier winds the line after drawing pin 811 outward, makes another the end of a thread be fixed on another outer drawing on the pin 811 of same end on the sub-coil holder 81 after coiling is finished; Has a rectangular box-like bobbin winder base 820 again on the bus-bar frame 82, its inner width is be matched with bobbin winder base 810 on the sub-coil holder 81 maximum outer wide, by with on the bobbin winder base 810 that is set in sub-coil holder 81,820 of the bobbin winder bases of this bus-bar frame 82 supply the elementary winding (not shown) of winding, the elementary winding of winding one the end of a thread in season is fixed on outer the drawing on the pin 812 that sub-coil holder 81 is held in addition earlier, wind the line again, another the end of a thread of winding was fixed on the sub-coil holder 81 with another outer drawing on the pin 812 of holding.
With aforementioned primary-secondary type coil holder 80 because of elementary winding and secondary winding respectively winding thereby have preferable isolation effect on sub-coil holder 81 and the bus-bar frame 82 separately independently on the bobbin winder base 810,820.But the winding mode of its coiling program and individual layer coil holder is several no different, and is also unreduced with regard to making technology, also has no way of reducing cost.
Summary of the invention
Therefore the utility model main purpose is to provide a kind of modular separately transformer of elementary winding and secondary winding that makes things convenient for, and it can effectively simplify the assembling processing procedure, and significantly reduces cost.
For reaching the major technique means that aforementioned purpose takes is to make aforementioned transformer have a primary-secondary type coil holder, and this primary-secondary type coil holder comprises:
One sub-coil holder mainly is that the side in one first bobbin winder base forms one first connecting seat, and first connecting seat is provided with several outer pins that draw; Wherein, first bobbin winder base is for winding one first winding, and the wire rod two ends of this first winding are connected with the outer pin that draws on aforementioned first connecting seat respectively;
One bus-bar frame mainly is that the side in one second bobbin winder base forms one second connecting seat, and second connecting seat is provided with several outer pins that draw; Wherein, first bobbin winder base that second bobbin winder base can be sub-coil holder places, and for winding one second winding, and the wire rod two ends of this second winding are connected with the outer pin that draws on second connecting seat respectively;
Have independently bobbin winder base and connecting seat on the aforementioned primary-secondary type coil holder factor, the bus-bar frame, its winding operation can fully independently make elementary winding and secondary winding have module of one's own, and only must simply make up action to these modules, can finish assembling, so processing procedure can significantly be simplified and reduce cost.
