参考如下定性分析的比较图所示，由其比较图得知，本发明确实能对传统意义上的电感进行性能上的明显改进，大大提高产品的性能，丰富产品的特性表现形式，能为用户某些特定的需求提供切实的解决方案，具有很强的新颖性、进步性和实用性。Referring to the comparison diagram of the following qualitative analysis, it can be seen from the comparison diagram that the present invention can indeed significantly improve the performance of the traditional inductor, greatly improve the performance of the product, enrich the characteristic expression of the product, and provide users with Some specific needs provide practical solutions, with strong novelty, progress and practicality.
此本发明组装式叠层电感装置可以通过片状体5、6的厚度来控制电感内的气隙大小并获得所须的电感量，其可以分成三种情形：The assembled laminated inductor device of the present invention can control the size of the air gap in the inductor and obtain the required inductance through the thickness of the sheets 5 and 6, which can be divided into three situations:
情形1：两个电感在同一电流下饱和时，电感可以当成是一个普通的电感使用。Case 1: When two inductors are saturated at the same current, the inductor can be used as an ordinary inductor.
情形2：当一圈电感量气隙小、电感比较高时，在电路的电流加大时先达到饱和，可以实现电感在小功率的情况下电感量比较高，在大电流的时候可以维持一定的电感水准。Situation 2: When the inductance of a circle is small and the inductance is relatively high, it will reach saturation first when the current of the circuit increases, so that the inductance of the inductance can be relatively high under the condition of low power, and can maintain a certain value under the condition of high current. inductance level.
情形3：当一圈电感量气隙电感比较低时，在电路的电流加大时两圈电感先达到饱和，此时一圈电感还维持接近原来的电感量，在小功率的情况下电感量比较高，在大电流的时候可以维持一定的电感水准，增加电路的可靠度。Situation 3: When the inductance of one circle and the air gap inductance are relatively low, the inductance of the two circles reaches saturation first when the current of the circuit increases, and the inductance of one circle remains close to the original inductance. Relatively high, it can maintain a certain level of inductance when the current is high, and increase the reliability of the circuit.
如图4至图6所示，由本发明实施时可将下铁心体4制成与下层容纳空间17相若大小，并将下铁心体4填入下层容纳空间17内，其实施是先将近似8字型金属片线圈1的弯脚15预先制成朝下或向外状，待置入下铁心体4后再其向内折弯，使其达到最大高度空间利用。As shown in Figures 4 to 6, the lower iron core body 4 can be made into the same size as the lower storage space 17 when the present invention is implemented, and the lower iron core body 4 is filled in the lower storage space 17. The bent leg 15 of the 8-shaped sheet metal coil 1 is pre-made downward or outward, and then it is bent inward after being placed in the lower iron core body 4, so as to achieve the maximum height space utilization.
如图7所示，由于电感间隙在不同的应用情形下要求不一样，其上铁心体2、中铁心体3、下铁心体4间的电感间隙也并非是必不可少，即由本装如上主要结构中于铁心体2、中铁心体3、下铁心体4间不加入片状体5、6，依然具有多层次线圈而获得电感装置良好电感量的组装式叠层电感装置。As shown in Figure 7, since the requirements for the inductance gap are different in different application situations, the inductance gap between the upper iron core body 2, the middle iron core body 3, and the lower iron core body 4 is not essential, that is, the main In the structure, there are no sheets 5 and 6 between the iron core body 2, the middle iron core body 3 and the lower iron core body 4, and there are still multi-layer coils to obtain an assembled laminated inductance device with good inductance of the inductance device.
