Furthermore, it should be understood that the terms "comprises" or "comprising," when used in various embodiments of the present disclosure, are intended to specify the presence of stated features, integers, operations, elements, components, or groups thereof, but do not preclude the presence or addition of one or more other features, integers, operations, elements, components, or groups thereof.

It will be understood that when an element (e.g., a first element) is "connected" to another element (e.g., a second element), the element can be directly connected to the other element, or there can be an intervening element (e.g., a third element) between the element and the other element.

The embodiment of the utility model provides a vertical combined inductor, as shown in fig. 1 and 2, which comprises a first inductor 100, a second inductor 200 and a connecting piece 300, wherein the first inductor 100 and the second inductor 200 are independent and complete inductors, and have functions and characteristics of the inductors. Specifically, the first inductor 100 includes a first magnetic powder block 110, a first coil 120 and two first electrodes 130, where the first magnetic powder block 110 may be formed by pressing magnetic powder, and wraps the first coil 120, and the two first electrodes 130 are fixed at the bottom of the first magnetic powder block 110 and electrically connected to the first coil 120 for connecting an external circuit. The second inductor 200 includes a second magnetic powder block 210, a second coil 220, and two second electrodes 230, wherein the second magnetic powder block 210 may be formed by pressing magnetic powder, which wraps the second coil 220, and the two second electrodes 230 are fixed at the bottom of the second magnetic powder block 220 and electrically connected to the second coil 220 for connecting an external circuit. The side surfaces of the first magnetic powder block 110 and the second magnetic powder block 210 are adhered together, specifically, the side surfaces of the first magnetic powder block 110 and the second magnetic powder block 210 can be adhered together through glue, and the connecting piece 300 is arranged on the top surfaces of the first magnetic powder block 110 and the second magnetic powder block 210 and is respectively connected with the first magnetic powder block 110 and the second magnetic powder block 210, so that the first magnetic powder block 110 and the second magnetic powder block 210 are secondarily fixed through the connecting piece 300.

In this embodiment, the two independent inductors of the first inductor 100 and the second inductor 200 are fixed together to form a combined inductor, and compared with the case that the first inductor 100 and the second inductor 200 are respectively fixed on a circuit board, the combined inductor greatly compresses the distance between the first inductor 100 and the second inductor 200, and can effectively reduce the space occupation of the circuit board. Meanwhile, the side surfaces of the first inductor 100 and the second inductor 200 are stuck together, and the top surfaces are connected together through the connecting piece 300, so that the connection between the first inductor 100 and the second inductor 200 is more stable.

In some embodiments, the top surface of the first magnetic powder block 110 is provided with a first groove 111, the top surface of the second magnetic powder block 210 is provided with a second groove 211 opposite to the first groove 111, and the first groove 111 and the second groove 211 both form openings on the side surface of the magnetic powder block, and the openings of the two are opposite. The connector 300 is disposed in the first recess 111 and the second recess 211. On the one hand, the first groove 111 and the second groove 211 can play a role in positioning the connecting piece 300, so as to limit the movement of the connecting piece 300, and on the other hand, the top surface of the combined inductor can be flatter.

In some embodiments, two ends of the connecting piece 300 are respectively adhered to the first magnetic powder block 110 and the second magnetic powder block 210, and the adhering manner is not easy to damage the magnetic powder blocks, so that the performance of the inductor can be ensured. The connector 300 may be an adhesive plate with adhesive.

In some embodiments, the connector 300 is an adhesive tape that is easier to handle and less costly than other means of attachment.

In some embodiments, the height of the first magnetic powder block 110 is greater than the length of the first magnetic powder block 110 and also greater than the width of the first magnetic powder block 110; the height of the second magnetic powder block 210 is greater than the length of the second magnetic powder block 210 and also greater than the width of the second magnetic powder block 210. The two inductors are erected, so that the area of the bottom surface of the inductor is smaller, and the space occupation of the circuit board can be further reduced.

Further, the first electrode 130 includes a first bending portion 131, and the first bending portion 131 is bent to the outer side surface (the side surface away from the second magnetic powder block 210) of the first magnetic powder block 110; the second electrode 230 includes a second bending portion 231, and the second bending portion 231 is bent to an outer side surface (a side surface away from the first magnetic powder block 110) of the second magnetic powder block 210. Thus, the exposed area of the electrode is larger, and the electrode is easier to weld and fix.

Further, the bottom of the outer side surface of the first magnetic powder block 110 is provided with a first accommodating groove, the first bending part 131 is located in the first accommodating groove, the bottom of the outer side surface of the second magnetic powder block 210 is provided with a second accommodating groove 212, and the second bending part 231 is located in the second accommodating groove 212, so that the first bending part 131 and the second bending part 231 shrink inwards, the distance of the outer side surface of the protruding magnetic powder block is reduced, and the space occupation is further reduced.

The foregoing is a further detailed description of the utility model in connection with specific embodiments, and it is not intended that the utility model be limited to such description.
