[0002] Chip inductors are electronic components that are small, light, and easy to install. They are widely used in the electronics field. Chip inductors consist of a magnetic core and a coil. The coil is wrapped around the magnetic core to form a certain inductance, and the two ends of the coil are connected to the circuit through lead wires. The material of the magnetic core is usually ferrite, magnetic material, or alumina ceramic. Chip inductors can be divided into many types according to material, structure, operating frequency band and other conditions, such as ferrite chip inductors, magnetic material chip inductors, lead-free chip inductors, etc. According to different operating frequency bands, they can be divided into several series such as low frequency, medium frequency, high frequency and ultra-high frequency.

The upper end of the connecting seat 205 is slidably connected inside the guide port 209. The setting of the guide port 209 can play a role of limiting and guiding the connecting seat 205.

[0028] A connecting plate 5 is fixedly mounted on the upper end of the upper cylinder 1 , and the inclined wall of the upper inclined block 203 contacts the inclined wall of the lower inclined block 204 , so that the lower inclined block 204 can be pushed to move by the downward movement of the upper inclined block 203 .

[0029] A limiting side plate 4 is fixedly installed inside the lower cylinder 3. There are three upper inclined blocks 203, and the three upper inclined blocks 203 are fixedly installed at the bottom of the push plate 202 at equal intervals.
