Generally for mechanization production is realized, adsorbing mechanism can be generallyd use when shifting inductance device, for the ease of inhaling
It is attached, need to be arranged the adsorption plane for being easy absorption on inductance device.For inductance device, upper magnetic core 3 is away from lower magnetic core 4
One side surface 32 is the biggish full surface of area, therefore usually as adsorption plane.However, small-sized with inductance device
Change, the area on surface 32 also decreases and becomes increasingly difficult to meet absorption needs.
In order to improve miniaturization inductance device adsorption effect, as shown in Fig. 2, the present embodiment is also set on the 100a of top surface
Be equipped with through slot 100b, insertion hole 106 extends to through slot 100b, it should be noted that due to lower magnetic core 4 need to auxiliary around
Line portion 12 is avoided, and upper magnetic core 3 and lower magnetic core 4 needs are oppositely arranged, thus the extending direction of upper through slot 100b with it is auxiliary
Helping the extending direction of winding section 12 will be mutually perpendicular to.At the same time, it also needs that adsorption structure 6 is arranged in inductance device, is carrying out
When the assembly of upper magnetic core 3 and inductance framework 1, upper magnetic core 3 is buckled on upper through slot 100b, and surface 32 is flat with top surface 100a
Together, adsorption structure 6 covers surface 32 and at least part top surface 100a simultaneously (referring to Fig. 8).It is removed in adsorption area at this time
