Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

As shown in fig. 1 to 4, the shielding type i-shaped inductor comprises an i-shaped magnetic core 3, a winding 4 is wound on the i-shaped magnetic core 3, a shielding cover 1 is sleeved outside the i-shaped magnetic core 3, a sealing cover 6 is clamped at the bottom of the shielding cover 1 through a clamping component 2, a pin 7 is welded at the bottom of the i-shaped magnetic core 3, and the bottom of the pin 7 penetrates through the sealing cover 6.

As shown in fig. 4, in this embodiment, the clamping assembly 2 includes a clamping post 21 penetrating through the shielding case 1, a sliding groove 22 is formed in an outer side of the clamping post 21 of the shielding case 1, a sliding block 24 is slidably disposed inside the sliding groove 22, the sliding block 24 is fixedly connected to the clamping post 21, a spring 23 is fixedly connected between the sliding block 24 and a side wall of the sliding groove 22, a clamping groove is formed in the sealing cover 6, and the clamping post 21 is matched with the clamping groove.

It should be noted that, by providing the locking post 21 and cooperatively providing the sliding slot 22, the sliding block 24, the spring 23 and the locking slot, the sealing cover 6 can be fixed on the shielding cover 1 by matching the locking post 21 with the locking slot.

As shown in fig. 4, in the present embodiment, a pulling plate 25 is fixedly mounted on a side of the locking column 21 away from the locking slot.

It should be noted that, here, by providing the pulling plate 25, the pulling of the catch 21 can be facilitated.

Referring to fig. 3, in the present embodiment, an air cushion 5 is disposed between the top of the i-shaped magnetic core 3 and the top inner wall of the shielding can 1.

It should be noted that, by providing the air cushion 5, the magnetic resistance of the magnetic circuit is increased, the linearity is improved, and the saturation current is increased, thereby eliminating the saturation of the inductance due to the addition of the shield case 1.
