Technical field
The present invention relates to a kind of core structure of the industries such as electronic transformer, magnet coil.
Background technology
In order to solve electromagnetic interference, reduce the problems such as volume of transformer, raising homogeneity of product and transmission efficiency, monolithic devices
The application of iron core increases year by year, and extends a variety of, and wherein main flow has two major classes, and one kind is hollow circular ring shape, during one kind is
Empty rectangle.But either which kind of structure, fail to solve pin fixation problem very well, but either inductance or transformer conduct
One electronic component, it is nearly all to be all integrally fixed on circuit board, so how to fix pin just into individual subject matter.
Fixation pin mode above existing market has two kinds, and a kind of is by lead being fixed on the small circuit board of customization according to product
On, it is welded on after lead is made standard installation on main circuit board, second is to do pin by detaining copper sheet on magnetic core, in copper sheet
Upper anchor leg.
The first scheme：Lead fix weld on circuit boards on circuit boards, after shaping, this scheme to copper cash outside
Footpath, hardness etc. are all required, so the scope of application is not wide, the circuit board for anchor leg need to be joined according to magnet ring size and coiling
The diversity and uncertainty for the species that to adjust, can so cause raw material are counted, prices of raw materials height is caused, equally to complete
The production of automaton metaplasia brings difficulty, causes production cost high, the finished product produced is to be used as pin, pole using after copper cash scolding tin
It is yielding to be inconvenient to pack and transport.
Second scheme：Copper sheet is detained on magnetic core, copper cash both ends are stuck on copper sheet, and this scheme copper cash can not complete automatic hanging feet
Action, copper cash subsequently need to be pressed into fixing groove, with mechanism action in copper cash riveting to copper sheet, welded after fixed.Such a side
Formula copper sheet fixing groove is easily deformed, and is caused cost of transportation high, can all be improved using rear finished product fraction defective and scrappage.And client makes
Because the shape after riveting has unstable setting in, it is welded on circuit board and has the skimble-scamble situation of profile.
