Abstract
The utility model provides a flat flat line of annular magnetic core is immediately around inductance, includes annular magnetic core, flat flat line circle, flat flat line ring is around setting up on the annular magnetic core, wherein two terminal wiring ends that are used for the connecting circuit board of respectively drawing of adjacent flat flat line circle in the flat flat line circle, annular magnetic core annular ring direction one side is located to the wiring end, the annular magnetic core is the magnetic metal powder core, flat flat line circle is flat enamelled copper wire, immediately around annular magnetic core winding displacement one deck. The utility model discloses use the magnetic metal powder core, flat flat line circle adopts the vertical wire winding of individual layer, and not only inductance distributed capacitance is little, EMC is effectual, moreover the coil radiating effect also better, the loss is low, can not take place the turn -to -turn short circuit for the during operation is more stable, and efficiency is higher.
Description
Technical field
This utility model relates to inducer field, and espespecially a kind of toroidal core flat wire is vertical around inductance.
Background technology
In prior art, ring-shaped inductors generally comprises toroidal core and the insulated conductor coil being wound on toroidal core.In order to change the power of ring-shaped inductors, often through changing the line footpath of insulated conductor or changing the number of turns that insulated conductor is wound around.When magnet ring radius is fixed, to increase the power of ring-shaped inductors, the insulated conductor using line footpath bigger is then needed to be wound on magnet ring or increase the number of turns that insulated conductor is wound around, both modes are used to make ring-shaped inductors the most crowded, and the method using flat-wise coil, flat more around the number of plies, product turn-to-turn capacitance is big, and work long hours poor radiation.
Utility model content
For solving the problems referred to above, this utility model provides a kind of toroidal core flat wire being beneficial to dispel the heat, distribution capacity is low, efficiency is high vertical around inductance.
For achieving the above object, the technical solution adopted in the utility model is: a kind of toroidal core flat wire is vertical around inductance, including toroidal core, flatwise coil, described flatwise coil is circumferentially positioned on toroidal core, the flatwise coil end that two of which in described flatwise coil is adjacent respectively draws one for connecting the terminals of circuit board, described terminals are located at side, toroidal core annular distance direction, described toroidal core is metal magnetic powder core, described flatwise coil is flat enamel covered wire, vertical around toroidal core winding displacement one layer.
Specifically, described toroidal core is Sendust Cores or ferrocart core magnet ring.
The beneficial effects of the utility model are: this utility model uses metal magnetic powder core, flatwise coil uses the vertical coiling of monolayer, not only inductance distribution capacity is little, EMC is effective, and coil radiating effect also more preferably, be lost low, turn-to-turn short circuit will not occur, when making work more stable, in hgher efficiency.
Accompanying drawing explanation
Fig. 1 is the vertical perspective view around inductance of toroidal core flat wire.
Drawing reference numeral illustrates: 1. toroidal core；2. flatwise coil；3. terminals.
Detailed description of the invention
Refer to shown in Fig. 1, this utility model is vertical around inductance about a kind of toroidal core flat wire, including toroidal core 1, flatwise coil 2, described flatwise coil 2 is circumferentially positioned on toroidal core 1, flatwise coil 2 end that two of which in described flatwise coil 2 is adjacent respectively draws one for connecting the terminals 3 of circuit board, described terminals 3 are located at side, toroidal core 1 annular distance direction, described toroidal core 1 is metal magnetic powder core, described flatwise coil 2 is flat enamel covered wire, vertical around toroidal core 1 winding displacement one layer.
Compared with prior art, this utility model uses metal magnetic powder core, and flatwise coil 2 uses the vertical coiling of monolayer, not only inductance distribution capacity is little, EMC is effective, and flatwise coil 2 radiating effect also more preferably, be lost low, turn-to-turn short circuit will not occur, when making work more stable, in hgher efficiency.
Specifically, described toroidal core 1 is Sendust Cores or ferrocart core magnet ring.
Below by specific embodiment, this utility model is further described.
Refer to shown in Fig. 1, this specific embodiment magnetic core 1 is metal magnetic powder core, use flat enamel covered wire vertical around, use automatic coil winding machine coiling, flatwise coil 2 end that wherein two in flatwise coil 2 are adjacent respectively draws one for connecting the terminals 3 of terminal and electronic wire, terminals 3 are positioned at the side in toroidal core 1 annular distance direction, and flatwise coil 2 is vertical around toroidal core 1 winding displacement one layer, and the also column distance between flatwise coil 2 is remote, inductance distribution capacity is little, good heat dissipation effect, is lost low, reduces temperature rise.
Embodiment of above is only to be described preferred implementation of the present utility model; not scope of the present utility model is defined; on the premise of without departing from this utility model design spirit; various deformation that the technical solution of the utility model is made by this area ordinary skill technical staff and improvement, all should fall in the protection domain that claims of the present utility model determine.
