Description
Technical field
The utility model relates to technical field of electronic components more particularly to a kind of structures of novel inductor coil.
Background technique
With the development of electronics technology, all kinds of electronic components have obtained wider application, especially inductance, wherein answering
It is high current one inductance with relatively broad inductance, uses the coil of flat type copper wire or circular copper wire around the home and iron powder using special
Different technique die casting one-pass molding, has the features such as resistance to high current, Low ESR.
In the prior art, inductance before the forming, needs for inductive type circle to connect with tablet spot welding one by one, then die casting
Insulated iron powder, it is silver-plated or tin plating in the electrode foot of inductance, then the inductor being fixed on tablet is separated by cutting machine
Out.Since coil dimension is small, rosin joint, burn-through, crackle or solder skip are be easy to cause when carrying out spot welding connection with tablet
The defects of, influence the quality and using effect of inductor.
Utility model content
The utility model mainly solves defect existing for present technology, provides a kind of structure of novel inductor coil.
In order to solve the above technical problems, the technical solution adopted in the utility model is:
A kind of structure of novel inductor coil, including tablet ontology, wire coil and electrode foot, the tablet ontology are two
Item the first metal plate and the second metal plate parallel to each other, the wire coil are uniformly arranged in first metal plate and second
Between metal plate, the electrode foot is integrally formed with the wire coil, is suppressed by the metal wire at the wire coil both ends
It forms, the free end of described two electrode foots is connect with the first metal plate and the second metal plate spot welding respectively.
Preferably, the wire coil turns to oval coil.
Preferably, the electrode foot is pressed into flat, electroplating surfaces with tin processing.
Preferably, the wire coil is formed by copper wire winding, and the copper line surface is coated with insulated paint.
The utility model has the beneficial effects that
The utility model provides a kind of structure of novel inductor coil, and electrode foot is the metal wire by coil both ends itself
It suppresses, eliminates the process that electrode foot and wire coil are subjected to spot welding connection originally, saved the production time, eliminated
The security risks such as rosin joint, solder skip, while decreasing resistance；It is integrated since electrode foot is suppressed using copper wire, and with tablet
Molding electrode foot is compared, high strength and deformation, make fixed inductance coil tablet when, do not need adjacent inductive it
Between increase support chip and fix, save material.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the structure of novel inductor coil of the utility model；
Fig. 2 is the partial enlargement structural representation of Fig. 1；
The cross-sectional view of Fig. 3 the utility model.
Figure label is as follows:
Tablet ontology 1；First metal plate 11；Second metal plate 12；Wire coil 2；Electrode foot 3.
Specific embodiment
The following figure be described with reference to the drawings and specific embodiment the present invention will be further described.
As depicted in figs. 1 and 2, the utility model provides a kind of structure of novel inductor coil, including tablet ontology 1, gold
Belong to coil 2 and electrode foot 3, the tablet ontology 1 is two the first metal plates 11 and the second metal plate 12 parallel to each other, described
Wire coil 2 is uniformly arranged between first metal plate 11 and the second metal plate 12, the electrode foot 3 and the metal wire
Circle 2 is integrally formed, and is suppressed by the metal wire at 2 both ends of wire coil, the free end difference of described two electrode foots 3
It is connect with the first metal plate 11 and 12 spot welding of the second metal plate.
In the present embodiment, 1 structure of tablet ontology is simple, only by the first metal plate 11 being parallel to each other and the second metal plate
12 composition, before eliminating with the integrally formed support chip of tablet ontology 1 and electrode foot.Due to electrode foot using copper wire suppress and
At, and compared with the integrally formed electrode foot of tablet, high strength and deformation, when making the tablet of fixed inductance coil, no
It needs to increase support chip between adjacent inductive to save material to fix.
In the present embodiment, the wire coil 2 turns to oval coil, and oval coil is the electricity with specific shape
Sensor, which matches, to be used, to obtain higher inductance and magnetic efficiency, for common circular coil, it is possible to use the structure,
It flattens the head and end of coil to form electrode foot, saves point welding process.
In the present embodiment, cross-sectional view as shown in Figure 3, the electrode foot 3 are pressed into flat, electroplating surfaces with tin processing.
In the present embodiment, the wire coil 2 is formed by copper wire winding, and the copper line surface is coated with insulated paint.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure made based on the specification and figures of the utility model is applied directly or indirectly in other relevant technologies
Field is also included in the patent protection scope of the utility model.
