Description

Technical Field

[0001] The utility model relates to the technical field of anti-interference inductors, in particular to an anti-interference high-current magnetic core structure. Background Art

[0002] An inductor is a component that converts electrical energy into magnetic energy and stores it. Its structure is similar to that of a transformer, but it has only one winding. An inductor has a certain inductance, which only blocks changes in current. If no current flows through the inductor, it will attempt to block current flow when the circuit is connected; if current flows through the inductor, it will attempt to maintain the current flow when the circuit is disconnected. Inductors are also called chokes, reactors, and dynamic reactors. Existing ferrite cores are all monolithic, making winding difficult due to the obstruction of the frame during winding. Utility Model Content

[0003] The utility model aims to provide an anti-interference large current magnetic core structure, which solves the problem of difficult winding.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an anti-interference high-current magnetic core structure, comprising a skeleton, a coil wound on the skeleton, and an inner magnetic core and an outer magnetic core. The skeleton is provided with a socket for inserting the inner magnetic core, and the outer magnetic core is a frame structure surrounded by a first magnetic core seat and a second magnetic core seat. The outer magnetic core is sleeved on the skeleton, and the two ends of the inner magnetic core are detachably connected to the first magnetic core seat.

[0005] By adopting the above technical solution: the inner magnetic core and the outer magnetic core adopt an assembled structure, the inner magnetic core is installed on the frame, and the outer magnetic core is spliced ​​by the first magnetic core seat and the second magnetic core seat. The inner magnetic core can be wound first and then connected to the outer magnetic core to complete the frame structure.

[0006] At least two connecting columns are fixed at each end of the first magnetic core seat, a clamping block is fixed at one end of the connecting column, and a buckle groove for slidingly engaging with the clamping block is opened on one side of the second magnetic core seat. The buckle groove is symmetrically arranged on the first magnetic core seat and is slidably engaged from the middle to both sides.

[0007] By adopting the above technical solution: the first magnetic core seat is provided with a connecting column and a clamping block, and the second magnetic core seat is provided with a buckle groove, so that the first magnetic core seat and the second magnetic core seat can be slidably clamped. Since the skeleton and the inner magnetic core are arranged in a frame structure surrounded by the first magnetic core seat and the second magnetic core seat, when the inner magnetic core is installed, the first magnetic core seat can be squeezed toward both ends, thereby making the connection between the first magnetic core seat and the second magnetic core seat more secure.

[0008] After the clamping block is connected to the buckle groove, the outer end surface of the first magnetic core seat is flush with the side surface of the second magnetic core seat.

[0009] By adopting the above technical solution, the aesthetics of the first magnetic core seat and the second magnetic core seat after being connected is ensured.

[0010] Grooves are provided on both side end surfaces of the skeleton, and ribs connected to the grooves are provided on the inner wall of the first magnetic core seat.

[0011] By adopting the above technical solution, the skeleton and the first magnetic core seat are connected via the grooves and the convex ribs, so that the skeleton has a positioning effect in the frame structure of the magnetic core.

[0012] Positioning grooves are provided at both ends of the inner magnetic core, and positioning blocks connected to the positioning grooves are provided on the inner wall of the first magnetic core seat.

[0013] By adopting the above technical solution: the positioning groove is connected with the positioning block, so as to ensure that the inner magnetic core and the outer magnetic core have a precise position after being connected, thereby improving the reliability of the magnetic core structure when in use.

[0014] Technical effects and advantages of this utility model:

[0015] 1. In this solution, the inner magnetic core and the outer magnetic core adopt an assembled structure. The inner magnetic core is installed on the frame, and the outer magnetic core is spliced ​​by the first magnetic core base and the second magnetic core base. The inner magnetic core can be wound first and then connected to the outer magnetic core to complete the frame structure.

[0016] 2. In this solution, the first magnetic core seat is provided with a connecting column and a clamping block, and the second magnetic core seat is provided with a buckle groove so that the first magnetic core seat and the second magnetic core seat can be slidably clamped. Since the skeleton and the inner magnetic core are arranged in a frame structure surrounded by the first magnetic core seat and the second magnetic core seat, when the inner magnetic core is installed, the first magnetic core seat can be squeezed toward both ends, thereby making the connection between the first magnetic core seat and the second magnetic core seat more secure.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] This embodiment provides Figure 1 The figure shows an anti-interference high-current magnetic core structure, which includes a skeleton 1, a coil 2 wound on the skeleton 1, and an inner magnetic core 3 and an outer magnetic core. The skeleton 1 is provided with a jack for inserting the inner magnetic core 3. The outer magnetic core of this embodiment is a frame structure surrounded by a first magnetic core seat 4 and a second magnetic core seat 5. The outer magnetic core is sleeved on the skeleton 1, and the two ends of the inner magnetic core 3 are detachably connected to the first magnetic core seat 4. The inner magnetic core can be wound first and then connected to the outer magnetic core to complete the frame structure, which facilitates the winding operation.

[0023] Furthermore, if Figure 2 As shown, at least two connecting posts 6 are fixed to each end of the first core seat 4, and a clamping block 7 is fixed to one end of the connecting post 6. The cross-section of the clamping block 7 and the connecting post 6 are T-shaped when combined. A buckle groove 501 is provided on one side of the second core seat 5, which is slidably engaged with the clamping block 7. The cross-section of the buckle groove 501 in this embodiment is L-shaped. The buckle groove 501 is symmetrically arranged on the first core seat 4 and the buckle groove 501 slides from the middle to both sides. The inner core 3 and the outer core adopt an assembled structure. The inner core 3 is inserted into the skeleton 1, and the outer core is spliced ​​by the first core seat 4 and the second core seat 5. The core material can be adjusted according to actual usage to meet the needs of high power and high current.

[0024] The first core seat 4 is provided with a connecting column 6 and a clamping block 7, and the second core seat 5 is provided with a buckle groove 501 so that the first core seat 4 and the second core seat 5 can be slidably clamped. Since the skeleton 1 and the inner core 3 are arranged in a frame structure surrounded by the first core seat 4 and the second core seat 5, when the inner core 3 is installed, the first core seat 4 can be squeezed toward both ends, thereby making the connection between the first core seat 4 and the second core seat 5 more secure.

[0025] Furthermore, after the clamping block 7 is connected to the buckle groove 501, the outer end surface of the first magnetic core base 4 is flush with the side surface of the second magnetic core base 5, thereby ensuring the aesthetics of the first magnetic core base 4 and the second magnetic core base 5 after connection.

[0026] like Figure 3 As shown, grooves 101 are provided on both side end surfaces of the skeleton 1, and ribs 401 are provided on the inner wall of the first core base 4, which are connected to the grooves 101. The skeleton 1 and the first core base 4 are connected by the grooves 101 and the ribs 401, so that the skeleton 1 has a positioning effect in the frame structure of the magnetic core.

[0027] Furthermore, in this embodiment, positioning grooves 301 are formed at both ends of the inner magnetic core 3, and positioning blocks 8 are formed on the inner wall of the first magnetic core base 4, which are connected to the positioning grooves 301. The connection between the positioning grooves 301 and the positioning blocks 8 ensures that the inner magnetic core 3 and the outer magnetic core are precisely positioned after connection, thereby improving the reliability of the magnetic core structure during use.
