Description

Technical Field

[0001] This utility model belongs to the field of inductor technology, and in particular relates to an inductor. Background Technology

[0002] An inductor is a component that converts electrical energy into magnetic energy and stores it. The structure of an inductor is similar to a transformer, but it has only one winding. An inductor has a certain inductance, which only impedes changes in current. If no current is flowing through the inductor, it will attempt to impede the current flow when the circuit is closed; if current is flowing through the inductor, it will attempt to maintain a constant current when the circuit is open. Inductors are also called chokes, reactors, or dynamic reactors.

[0003] Existing inductors have poor heat dissipation during use, resulting in low overall heat dissipation performance and inconvenience in use. Furthermore, during use, when the wire and the wound magnetic core are intertwined, the lack of a protective structure on the outer surface of the wire makes it easy for the wire to wear against the wound magnetic core.

[0004] The purpose of this invention is to provide an inductor that solves the problems mentioned above by designing the wound magnetic core, wire, heat dissipation ring, and convex insulating cotton tube.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an inductor, including a wound magnetic core and a wire. The wire is wound circumferentially on the surface of the wound magnetic core. Heat dissipation rings are fixedly sleeved on the top and bottom of the wound magnetic core. Convex insulating cotton tubes are respectively sleeved and fixed on the fixed part and bottom of the two heat dissipation rings.

[0007] Both ends of the wound magnetic core are provided with a first bonding groove in a ring array; a heat dissipation through hole is provided at the bottom of the first bonding groove; the heat dissipation through hole penetrates the wound magnetic core.

[0009] As a preferred technical solution of this utility model, an annular groove is formed on the top of the heat dissipation ring near the inner side.

[0010] The top of the convex insulating cotton tube is provided with a second bonding groove in a ring array; the bottom of the second bonding groove is sleeved with the top of the arc-shaped bonding plate.

[0013] As a preferred technical solution of this utility model, annular insulating cotton is snapped and fixed inside the two annular grooves; the outer peripheral side of the annular insulating cotton is provided with several winding arc grooves.

[0014] The outer surface of the wire body is slidably engaged with the inner surface of the winding arc groove; the outer surface of the wire body is slidably engaged with the inner top of the second fitting groove in the convex insulating cotton tube.

[0015] As a preferred embodiment of this utility model, the outer surface of the wire body is slidably engaged with the outer surface of the convex insulating cotton tube, and the convex insulating cotton tube is made of polyester insulating cotton.

Specific Implementation Example 2:

[0035] Based on Specific Embodiment 1, the difference in this embodiment is as follows:
