Description

Technical Field

[0001] The utility model relates to the field of magnetic cores, in particular to a magnetic core assembly convenient for wire routing. Background Art

[0002] The structure of an inductor mainly consists of a coil winding and a magnetic core. To reduce external interference to the inductor, many inductors are provided with a protective shell on the outside. However, after the protective shell is provided, the wire routing of the two end joints of the coil winding (i.e., the two joints connected to the external circuit) becomes very inconvenient. The current inductor chooses to wind fewer turns of the coil to reserve wire routing space for the two end joints of the coil, but this reduces the number of turns of the coil and will reduce the performance of the inductor.

[0003] In the Chinese utility model patent with the publication number of CN217788168U, a magnetic core assembly convenient for wire routing is disclosed. The coil is wound on the magnetic core body. After winding, the protective shell and the magnetic core body are bonded by glue. The two joints of the coil pass through the wire passing space and the groove to be connected to the external circuit. In this way, there is no need to reserve wire routing space, and the number of turns of the coil wound on the magnetic core body can reach the maximum under the condition that other conditions are the same, improving the performance of the inductor.

[0004] In the above structure, the outside of the magnetic core body contacts the protective shell through a limiting ring. Among them, the contact between the limiting ring and the protective shell is a line contact, and the contact area between the two is small, which makes the connection firmness poor. For this reason, we have designed a magnetic core assembly convenient for wire routing. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a magnetic core assembly convenient for wire routing.

[0006] The utility model is realized by adopting the following technical solutions: a magnetic core assembly convenient for wire routing, including a magnetic core body, a front cover shell is sleeved on the front side of the outside of the magnetic core body, a rear cover shell is sleeved on the rear side of the outside of the magnetic core body, and the inner sides of the front cover shell and the rear cover shell are connected by interference fit;

[0007] The magnetic core body includes a magnetic core column, a side ring is fixed at each of the front and rear ends of the outer circle of the magnetic core column, six communication notches are formed by concave depressions on the outer surface of the side ring, and the six communication notches are circumferentially and arrayedly distributed. The outside of the magnetic core body is connected to the inside of the front cover shell and the rear cover shell through the communication notches.

[0008] As a further improvement of the above solution, three groups of annularly distributed wire routing notches are opened on the front side of the front cover shell, and the wire routing notches extend backward through both ends of the rear cover shell. The three groups of wire routing notches are correspondingly arranged with the six communication notches. The design of the wire routing notches enables the inside of the front cover shell and the rear cover shell to have a special space for wire routing, facilitating the wires to be placed outside through the communication notches and the wire routing notches.

[0009] As a further improvement of the above solution, three groups of mating blocks are arranged on the inner sides of the front cover and the rear cover near one end of the side ring. The three groups of mating blocks inside the same front cover and rear cover are respectively placed between two adjacent wire routing notches. The mating blocks are snapped into the communication notches. The shape and size of the mating blocks match those of the communication notches, and the two are connected by interference fit, so that the front cover and the rear cover can be firmly fixed to the magnetic core body, facilitating subsequent processing.

[0010] As a further improvement of the above solution, the two ends of the communication notch are rounded at the connection with the outer ring of the side ring to form an arc-shaped extension surface, and the two ends of the wire routing notch are rounded to form an arc surface. The design of the arc-shaped extension surface and the arc surface avoids scratches caused when the circuit is placed inside the communication notch and the wire routing notch.

[0011] As a further improvement of the above solution, three groups of docking interfaces distributed in a ring are provided on the rear side of the front cover, and three groups of docking blocks distributed in a ring are provided on the front side of the rear cover. The docking blocks are inserted into the docking interfaces by interference fit, facilitating the quick installation and fixation of the front cover and the rear cover.

[0012] As a further improvement of the above solution, the front end of the front cover is flush with the outer surface of the front side of the side ring, and the tail end of the rear cover is flush with the outer surface of the rear side of the side ring, with the overall lengths being the same.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The outer rings of the side ring, the front cover and the rear cover of the present utility model are all circular structures, and the outer ring of the side ring is in contact with the inner rings of the front cover and the rear cover. With the multiple mating blocks provided in cooperation, they can be quickly connected to the side ring, and the contact area between the three is large, improving the connection firmness.

[0015] 2. By providing a communication notch on the outer ring of the side ring and multiple wire routing notches on the inner rings of the front cover and the rear cover, the coils in the magnetic core assembly can be routed through the communication notch and the wire routing notches, and the design of the arc-shaped extension surface and the arc surface avoids scratches caused when the circuit is placed inside the communication notch and the wire routing notches.
