Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Embodiment：
Referring to Fig. 1, the utility model provides a kind of technical scheme：A kind of high-frequency inductor, including plastic frame 1, it is described
The bottom of plastic frame 1 is inlaid with support base 2, and the plastic frame 1 and the inside of support base 2 are groove structure, recessed
Wound core 3 is installed with inside groove, the surface of the wound core 3 is uniformly wrapped with inductance coil 4, the electricity clockwise
The two ends of sense coil 4 lead to wiring pin 5, and the wiring pin 5 is spread out of from support base 2, pair of the support base 2
Answer to dig on position and have mounting hole 6；The input of left side wiring pin 5 is connected with resettable fuse 7, right-hand member wiring pin
It is connected with indicator lamp 8 at 5, the indicator lamp 8 is connected with wiring pin 5 by wire and is fixed on the upper surface of plastic frame 1；
The inductance coil 4, which is located on the position in the middle of wound core 3, is provided with auxiliary electrode 9, wound core 3 and auxiliary electrode 9 it
Between leave air gap 10；
