[0003] However, the first core and the second core of the inductance are only combined by each combined part and each combination part in a concave-convex complementary manner, and there is no connection between the inductance and the substrate. If not properly fixed, the inductance may move or fall when it is placed on the substrate, which will affect the stability and reliability of the circuit. Or more seriously, there is no correct contact or connection point on the substrate, which may cause poor contact between the inductance and the substrate, and further cause unstable circuit, signal attenuation, or even complete failure to work.

[0004] Therefore, how to eliminate the above-mentioned defects is the technical difficulty that the present inventor wants to solve. UTILITY MODEL CONTENTS
