Description

Technical Field

[0001] The utility model relates to the technical field of inductance, in particular to an inductance. Background Art

[0002] The coil inside the inductor will generate a magnetic field when power is supplied, and the magnetic core material covering the coil cannot shield the magnetic field generated by the coil, which eventually leads to magnetic leakage of the inductor. The magnetic leakage of the inductor will cause the subsequent inductor to interfere with other electronic components during use, so the inductor needs to be shielded from the magnetic field. In the prior art, a layer of metal cover is usually coated on the outside of the inductor to prevent the phenomenon of magnetic leakage of the inductor. However, the shielding cover currently used generally extends from the side of the inductor to the bottom, so that the inductor and the shielding cover are tightly set. However, since the shielding cover is generally made of metal, after it is set to the bottom of the inductor, it is easy to form a short circuit at the integrated circuit during the use of the inductor, thereby affecting the performance of the inductor. Utility Model Content

[0007] Optionally, a first adhesive layer is disposed between the first side cover and the first side portion to bond the first side cover and the first side portion together.

[0008] Optionally, a second adhesive layer is provided between the second side cover and the second side portion to bond the second side cover and the second side portion together.

[0009] Optionally, there are a plurality of the at least one inductor element, the plurality of inductor elements are arranged in parallel, and the first side portion and the second side portion are side portions of the first and last two inductor elements respectively, which are away from other inductor elements.

[0010] Optionally, a third bonding layer is provided between two adjacent inductor elements to bond the two adjacent inductor elements together.

[0011] Optionally, the electrode sheets of the first and last inductor elements extend from the bottom of the corresponding inductor element to the corresponding first side portion or the second side portion.

The second side cover 122 extends from the top of the second side portion 112 to between 1 / 2 of the height of the second side portion 112 and the bottom.

[0030] Specifically, in this embodiment, the first side portion 111 and the second side portion 112 are the sides through which the magnetic field of the inductor 100 passes, and if there is no shielding cover 120, the inductor 100 is prone to magnetic leakage at the first side portion 111 and the second side portion 112. Generally speaking, the shielding cover 120 is made of metal.

[0031] Specifically, in this embodiment, a first side cover 121 is provided at the first side portion 111 of the inductor element 110, and a second side cover 122 is provided at the second side portion 112. The first side cover 121 and the second side cover 122 respectively shield the magnetic field leaking from the first side portion 111 and the second side portion 112. In addition, since the first side cover 121 extends from the top of the first side portion 111 to between 1 / 2 of the height of the first side portion 111 and the bottom, and the first side cover 121 extends from the top of the first side portion 111 to between 1 / 2 of the height of the first side portion 111 and the bottom, the first side cover 121 and the second side cover 122 can shield the first side portion 111 and the second side portion 112, and avoid a short circuit phenomenon when the inductor 100 is used.

[0036] As a specific embodiment of the present invention, the number of at least one inductor element 110 in this embodiment is multiple, and the multiple inductor elements 110 are arranged in parallel, and the first side portion 111 and the second side portion 112 are the side portions of the first and last two inductor elements 110 away from other inductor elements 110 respectively.

[0037] Specifically, Figure 3 As shown, taking the number of inductance elements 110 as 2 as an example, the inductance 100 in this embodiment includes a first inductance element 110a and a second inductance element 110b, respectively, and each inductance element 110 includes a coil and a magnetic material wrapped outside the coil. The coil axis of this embodiment is arranged horizontally, so the left side of the first inductance element 110a is the first side portion 111, and the right side of the second inductance element 110b is the second side portion 112. The first side cover 121 of this embodiment is arranged on the left side of the first inductance element 110a, and the second side cover 122 is arranged on the right side of the second inductance element 110b. Thereby, magnetic leakage on the left and right sides of the inductance 100 is avoided.

[0038] In addition, since the inductor 100 in this embodiment is composed of a plurality of inductor elements 110 arranged in parallel, and the axis of the coil in each inductor element 110 is arranged horizontally, the inductance value under the same occupied area can be increased, and the inductance value per unit area can be increased.

[0044] Specifically, Figure 1 , Figure 3 or Figure 5 As shown, each inductor element 110 is provided with a groove 116 at the position where the electrode sheet 113 is provided, so that the electrode sheet 113 can be disposed in the groove 116 , thereby preventing the electrode sheet 113 from protruding.

[0046] Specifically, the top cover 123 of the present embodiment connects the first side cover 121 and the second side cover 122 on one hand, and also serves to shield the top of the inductor 100 on the other hand.

[0047] Specifically, the shape and size of the top cover 123 are the same as the shape and size of the top of the inductor 100 .

[0048] As a specific embodiment of the present invention, at least one inductor element 110 of this embodiment may further include a third side portion 114 and a fourth side portion 115 opposite to each other. The shielding cover 120 may further include a third side cover 124 and a fourth side cover 125 connected to the top cover 123, wherein the third side cover 124 extends from the top cover 123 to the third side portion 114, and the fourth side cover 125 extends from the top cover 123 to the fourth side portion 115.
