Description
Technical field
The present invention relates to printed circuit board (PCB) substrate mounted type inductors, relate more specifically to a kind of cut off to outside
Magnetic field shielding type inductor.
Background technique
In general, inductor is to utilize the work of electromagnetism that occurs to the coil flowing electric current for being wound in magnetic core (Core)
Passive part, as the spiral quantity increases, inductance value becomes larger.Inductor and capacitor bank and constitute resonance electricity
Road is simultaneously used in filter circuit, is also used in impedance matching.In the characteristic of observed frequency, it is however generally that, frequency is higher, reactance
Ingredient increases, but because of the feature of the geometry of the characteristic and inductor that are used in the material that inductor manufactures and between coil
Parasitic capacitance of generation etc. influences, and the behavior changes.
Also, electromagnetic property needed for frequency of suit (set) that inductor is applicable according to it etc. and divide into spiral
Formula, stacked, diaphragm type, laser spiral (laser helixing type) etc..Winding wire type Q due to the resistance value of conducting wire is small
Value is high, and because the parasitic capacitance value generated between coil is small, magnetic resonance frequency (Self Resonant Frequency) is high, and has
There are an outstanding characteristics such as high capacity, high voltage-resistent characteristic, but exists and be difficult to relatively small and production is low and lead to price height
The shortcomings that.It is stacked to embody outstanding characteristic, but there is limitation, there is miniaturization and outstanding and cheap excellent of production
Point, thus, it is widely used, diaphragm type is used in the fine capacity for requiring tight tolerance (tight tolerance) characteristic
The field of control, but there is limitation in the capacity for realizing wide scope, and have the shortcomings that production is low and price is high.
In addition, being made with being mounted on the master control borad of the electric field of the household appliances such as TV, automobile (Main Control Board)
Shielding type inductor and know.
Fig. 1 is the exploded perspective view for showing the shielding type inductor 1 of the prior art, and (a) of Fig. 2 is the display prior art
The plan view of shielding type inductor 1, (b) of Fig. 2 are the bottom view for showing the shielding type inductor 1 of the prior art.
Shown in showing such as Fig. 1 to Fig. 2, the shielding type inductor 1 of the prior art includes: connecting terminal 21, passes through soldering
It is connect with coil 40；Pedestal 10 has the attachment terminal 22 connecting with PCB substrate (not shown)；Magnetic core 30, it is vertical to be mounted on institute
Pedestal 10 is stated, for convolute coil 40；Coil 40 is wound in the magnetic core 30, is connect by soldering with the connecting terminal 21；Outside
Shield (shield outer) 50 is formed with through hole 51 with up and down direction, outer to be inserted into the magnetic core 30 for being wound with the coil 40,
Lower end is installed on the pedestal 10, and covers the magnetic field of the coil 40.
Also, the terminal receiving channel groove being outwardly concaved by inner peripheral surface 50a is formed in the inner peripheral surface 50a of outer shield 50
52, the connecting terminal 21 being bent upwards is contained in the inside of outer shield 50.
Also, the manufacturing method of the shielding type inductor 10 of the prior art is as follows.
Firstly, preparing that there is connecting terminal 21 and mounting the pedestal 10 of terminal 22.
After magnetic core 30 is mounted on pedestal 10, by coil 40 wound on magnetic core 30, and coil 40 is passed through into soldering
And it is wired to connecting terminal 21.
Also, with insulating tape winding institute coiled coil 40 (not shown), for insulating.
Later, it by the perpendicularly inward lateral bend of connecting terminal 21 with 40 wiring of coil, is wound with being inserted into outside outer shield 50
The magnetic core 30 of coil 40.
At this point, the connecting terminal 21 of vertical curve is contained in terminal receiving channel groove 52, outer shield 50 is smooth as a result,
The magnetic core 30 for being wound with coil 40 is inserted into outside ground.
Finally, adhesive 60 is injected the space between outer shield 50 and magnetic core 30, bonding outer shield 50 and magnetic core 30.
But there is following problem in the shielding type inductor 1 of the prior art.
Currently, it is necessary to upward vertical curve connecting terminal 21, to be used for outer insertion outer shield 50.Vertical not curved upwards
In the case where song, it is difficult to be inserted into outer shield 50.
Because need to by the upward vertical curve of connecting terminal 21, thus, it is desirable to be bent connecting terminal 21 upward vertical curve dress
It is standby, and there are problems that the manufacturing expense for increasing flow chart and increasing product on the whole.
Also, necessary to be because of the upward vertical curve operation of connecting terminal 21, for connecting terminal 21 and coil occurs
The case where being contacted between 40, and there are short circuit phenomenons.
Also, as described above, there is following problem, in order to accommodate the connecting terminal 21 to upside vertical curve, outside
The inner peripheral surface of shield 50 must form four terminal receiving channel grooves 52.
In order to solve the problems, such as the short-circuit of terminals, it is necessary to by the process of winding insulating tape, become and increase manufacturing process
With improve product manufacturing cost the reason of.
Also, when considering current characteristics, it need to ensure to be bent the space of connecting terminal 21, as a result, in order to ensure bending is empty
Between, the spiral quantity of a large amount of coil 40 can not be formed.As a result, because the spiral quantity of coil 40 cannot be too many, and there is sense
The problem for answering coefficient (magnetic volume) few.
Also, when considering current characteristics, therefore, to assure that the curved space of connecting terminal 21, as a result, in order to ensure bending
There is the shortcomings that outer diameter (sectional area of coil) that can not increase line in space.As a result, the case where can not increase the outer diameter of line
Under, there is also can not apply big electric current.
Also, because connecting terminal 21 is bent, and it is packed into the inside of outer shield 50, connecting terminal can not be carried out as a result,
The visual inspection of 21 soldering.
Also, injection adhesive 60 is also needed in four terminal receiving channel grooves 52, the amount of adhesive 60 is made more as a result,
At a large amount of wastes of material, and, it is difficult to four terminal receiving channel grooves 52 all are uniformly injected into, and adhesive is caused to be infused
It is very low to enter workability, and during injection, do not keep uniformly, because of non-uniform injection, and leads to that bonding work has occurred
The bad problem of industry.
