Description
Technical field
The utility model relates to surface attaching type magnetic elements.
Background technique
Current assembly type power inductance needs for coil windings to be pre-formed as a specific shape when being assembled
Shape needs to carry out one to semi-finished product 12 at this time as shown in Figure 1, obtaining semi-finished product 12 after coil windings 10 are packed into magnetic core 11
The process of pressure side makes coil windings 10 be shaped to final shape 13, is then loaded on magnetic core 14, obtains final product
15.In Fig. 1, dotted arrow represents assembly and assembly direction, realizes that arrow represents process flow trend.Such assembling side
The process of formula, pressure side needs to occupy production time and processing step, will certainly reduce packaging efficiency and increase production
Cost.
Utility model content
The main purpose of the utility model is that proposing a kind of assembly type magnetic device without carrying out the sub- process of pressure side, group
Coil windings can be directly shaped to the shape when final products form when dress, be housed to after magnetic core no longer need to carry out terminal it is whole
Shape saves processing step and cost, substantially reduces the production period.
The utility model proposes following technical scheme for the above-mentioned purpose:
A kind of surface attaching type magnetic elements, including the first magnetic core, the second magnetic core and coil windings；First magnetic
There is coil accommodation groove on core；The coil windings have the bending shape consistent with the coil accommodation groove before assembling,
The coil windings are embedded into the coil accommodation groove in such a way that side enters slot, and the coil windings are exposed outside after insertion
Side flushed with the one side of first magnetic core, formed middle contact；Second magnetic core and the middle contact
It is bonded by glue, to form air gap between second magnetic core and the middle contact, obtains air gap perpendicular to attachment
The magnetic elements in face.
Further, the both ends of the coil windings are exposed to the both ends of first magnetic core；The coil windings
Two bottoms be exposed to the bottom of first magnetic core, as pasted electrode.
The surface attaching type magnetic elements of the aforementioned offer of the utility model, coil windings are just made as it in advance before assembling
Shape in the final product, therefore coil windings are packed into after the coil accommodation groove of magnetic core, without carrying out shaping again, directly
Another magnetic core is mixed in tipping.So as to saving a procedure, saving production cost and shortening the production period.
Detailed description of the invention
Fig. 1 is the structure and process flow for assembling figure of existing assembly type power inductance；
Fig. 2 is the structure and process flow for assembling figure of the assembly type power inductance of the utility model.
Specific embodiment
Below against attached drawing and in conjunction with preferred embodiment, the utility model is described in further detail.
It is to be appreciated that "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom",
Orientation or positional relationship indicated by the term of the indicating positions such as "inner", "outside" is that orientation based on the figure or position are closed
System is merely for convenience of description and simplification description, rather than the device or element of indication or suggestion meaning must have specifically
Orientation is constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.
In addition, the dotted arrow in attached drawing indicates to carry out the direction of component assembly and assembly, solid arrow indicates assembly
Process flow trend.
Specific embodiment of the present utility model provides a kind of surface attaching type magnetic elements, which can be with
It is inductance component or transformer, with reference to Fig. 2, the magnetic elements include the first magnetic core 21, the second magnetic core 22 and coil
Winding 20, wherein there is the coil accommodation groove for accommodating coil windings on the first magnetic core 21, and the setting of coil accommodation groove makes
Coil windings can only be embedded in such a way that side enters slot when must assemble；The coil windings 20 have and the coil before assembling
The consistent bending shape of accommodation groove, and be embedded into the coil accommodation groove in such a way that side enters slot, the line after insertion
The circle exposed side of winding 20 is flushed with the one side of first magnetic core 21, forms middle contact；Second magnetic
Core 22 is Nian Jie by glue with the middle contact, to form gas between second magnetic core and the middle contact
Gap obtains air gap perpendicular to the magnetic elements 40 in attachment face.For coil windings 20 after being embedded in the first magnetic core, both ends are naked
It is exposed to the both ends of the first magnetic core 21；And two bottoms (two terminals of coil windings) are exposed to the bottom of the first magnetic core 21, just
It is used as component mounter electrode well.That is, the air gap formed between two magnetic cores of the magnetic elements of the utility model is
Perpendicular to attachment face.
For aforementioned magnetic elements provided by the utility model in assembling, coil windings 20 are directly to be bent into finally to exist
Shape in product, such as Fig. 2 are embedded into the coil accommodation groove of the first magnetic core 21 after bending is good in such a way that side enters slot,
Obtain semi-finished product 30；Then again that the second magnetic core 22 is Nian Jie using glue with semi-finished product 30, assembling is completed, final air gap is obtained
Perpendicular to the magnetic elements 40 in attachment face.Assembling procedure is simple, and packaging efficiency is high.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For those skilled in the art of the present invention
For, without departing from the concept of the premise utility, several equivalent substitute or obvious modifications, and performance can also be made
Or purposes is identical, all shall be regarded as belonging to the protection scope of the utility model.
