Abstract
The utility model discloses a coil magnetic core assembly. The coil magnetic core assembly comprises a coil, a magnetic core and a PCB. The coil surrounds a middle pillar of the magnetic core, and the PCB is connected with a pin of the flat coil by arranging a pin of a metal nail into the PCB and a pin hole of the coil and welding the pin. According to the flat coil magnetic core assembly, the pin outlet reliability is high, and the good machining and welding performance is achieved.
Description
Technical field
The utility model relates to coil at the leg structure that goes out of magnetic core, belongs to electric component technical field.
Background technology
In large current product, for meeting properties of product, by coil windings, be directly wound on magnetic core and by coil and directly go out pin, guarantee with magnetic core bottom coplanarly, then carry out paster.But in process practice, find, because product easily occurs that when crossing Reflow Soldering glue is softening, to follow metal heat-expansion shrinkage effect simultaneously, cause patch products coplanar bad, failure welding, has affected the productive rate of product.
Summary of the invention
For the defect of prior art, the utility model discloses a kind of coil core assembly, do not affecting under the prerequisite of product encapsulation, use peg as switching pin, and fix by pcb board, guarantee that product has good welding performance man-hour adding.
For achieving the above object, the utility model is achieved through the following technical solutions:
A coil core assembly, comprises coil, magnetic core, pcb board, and wherein coil encircling is on the center pillar of magnetic core, and pcb board is connected with flatwise coil pin, and connected mode is for peg pin being packed into the pin bores of pcb board and coil, by its welding.
Mode by adopting peg to be welded and fixed, has effectively guaranteed that paster adds the reliability in man-hour.
Preferably, in order to guarantee heat dispersion and anti-EMI performance, described coil is flatwise coil, includes but not limited to FPC or FFC.
Wherein, above-mentioned peg adopts the good metal material of electric conductivity, and for example iron nail, fastener, aluminium nail, be preferably fastener.
In order to prevent that peg from affecting welding operation, peg bottom is coplanar with magnetic core bottom.
For the ease of manufacturing processing, described magnetic core is preferably combining structure, upper magnetic core and lower magnetic core, consists of.
Accompanying drawing explanation
Figure 1A, 1B, 1C are respectively front view, vertical view and the right view of coil core assembly of the present utility model.
Embodiment
With reference to accompanying drawing 1A, 1B, 1C, coil core assembly of the present utility model, magnetic core 2 used, by upper magnetic core 22, lower magnetic core 21 combining structures, first packs pcb board 3 in lower magnetic core 21 into when assembling, then packs flatwise coil 1 into, fastener pin 4 is packed in pcb board and flatwise coil pin bores again, reinstall magnetic core 22, then by welding manner by pcb board, flatwise coil, the welding of fastener pin guarantees that fastener bottom is coplanar with magnetic core bottom simultaneously.
Claims (5)
1. a coil core assembly, is characterized in that comprising coil, magnetic core, pcb board, and wherein coil encircling is on the center pillar of magnetic core, and pcb board is connected with flatwise coil pin, and connected mode is for peg pin being packed into the pin bores of pcb board and coil, by its welding.
