Below in conjunction with specific embodiment specific implementation of the present utility model is described in detail:
Embodiment one:
Fig. 2 shows the structural representation of the laminated chip inductor that the utility model first embodiment provides, and for convenience of explanation, only shows the part relevant with the utility model embodiment.
This inductor comprises loam cake 1, lower cover 2 and a plurality of insulating barrier 3, all is provided with electrode unit 4 at each surface of insulating layer, and the electrode unit 4 on a plurality of insulating barriers has formed several complete coils, constitutes the basic structure of inductor.Existing laminated chip inductor mostly is 3/4 interior electrode structure, promptly 4 single-layer electrodes unit form 3 complete coil, present embodiment improves the coil composition, electrode unit in the individual layer is prolonged, around a circle half, make 2 single-layer electrodes unit form 3 complete coil, promptly form 3/2 interior electrode structure.Like this, for the inductor of equal length, the inductance value of 3/4 interior electrode structure inductor that 3/2 interior electrode structure inductor that present embodiment provides is more traditional doubles at least.
This 3/2 interior electrode structure adopts the lamination sheet type component manufacturing technology to make, and concrete making flow process is as follows:
The first step: form first insulating barrier, in first Jie's insulation, form the ground floor electrode unit;
Second step: above the ground floor electrode unit, form second insulating barrier, and on second insulating barrier, offer through hole, in through hole, fill conductor, the end of ground floor electrode unit and conductor are joined with the terminal corresponding position of ground floor electrode unit;
The 3rd step: on second insulating barrier, form second layer electrode unit, the initiating terminal of second layer electrode unit and the conductor in the through hole are joined, first, second layer electrode unit is connected;
Form the 3rd insulating barrier, triple electrode unit successively according to the aforesaid operations flow process, the 4th insulating barrier, the 4th layer of electrode unit, until last layer insulating and electrode unit, and make between the adjacent layer electrode unit by the conductor in the through hole on each insulating barrier and to connect.
In the above-mentioned electrode structure, be loaded with 1.5 circle electrodes on every layer insulating, 2 single-layer electrodes unit can form 3 complete coils, form 3/2 interior electrode structure.Be appreciated that, in the practical operation flow process, factors such as the complexity of comprehensive manufacturing process and operating efficiency, electrode on ground floor insulating barrier and last layer insulating can not be 1.5 circles, its concrete length is decided according to the practical operation situation, and its minute differences there is no considerable influence to the performance of inductor.
Following form is the relevant parameter table of comparisons of described 3/2 the interior electrode structure of present embodiment and traditional 3/4 interior electrode structure inductor:
Table one. the performance parameter table of comparisons when printing tie point number is identical
| The electrode structure type | Printing tie point number | The electrode number of | Inductance value | |
| 3/4 interior electrode | 10 | 7.5 circle | 4.7 |
|
| 3/2 interior electrode | 10 | 14.5 circle | 12uH |

| The electrode structure type | The internal electrode number of turns | Printing |
| 3/4 interior electrode | 14.5 circle | 19 |
| 3/2 interior electrode | 14.5 circle | 10 |
By above table as can be known, when tie point number (the total number that is equivalent to the through hole on the insulating barrier) was identical, the inductance value of 3/2 interior electrode structure inductor generation was more than two times of 3/4 interior electrode structure inductor of tradition; In the time will obtaining the electrode coil of equal number, 3/2 required tie point number of interior electrode structure only is about 1/2 of 3/4 interior electrode structure of tradition.By above table as seen, under the identical situation of inductance value, the inductor that present embodiment provides can be saved a plurality of tie points, saves and makes man-hour, enhances productivity.
