Description

Technical Field

[0001] The utility model relates to the technical field of soft magnetic cores, in particular to a soft magnetic core provided with an electromagnetic shielding cover. Background Art

[0002] Soft magnet core is a special magnetic material, mainly used as a component of the magnetic circuit in electromagnetic equipment. This type of core is characterized by high magnetic permeability and low coercive force. It can be easily magnetized under the action of an external magnetic field, and can be quickly demagnetized after the external magnetic field is removed, with almost no residual magnetism. The soft magnet core with an electromagnetic shielding cover is designed to reduce the impact of the external magnetic field on the core itself and reduce the electromagnetic interference generated by the core to the external environment.

[0003] When using the current soft magnetic cores with electromagnetic shielding covers, workers often find that most of the current electromagnetic shielding covers are installed by welding. Since many electromagnetic shielding covers are small in size, it is difficult for workers to limit them during welding. During the welding process, the electromagnetic shielding covers are prone to shifting, which affects product quality. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a soft magnetic core with an electromagnetic shielding cover.

[0006] The effect achieved by the above components is: the magnetic core body is placed in the lower shielding cover, and the four mounting posts are respectively inserted into the corresponding mounting grooves, so that the lower shielding cover and the upper shielding cover can be quickly installed together, thereby avoiding the current electromagnetic shielding covers that are mostly installed by welding. Since many electromagnetic shielding covers are small in size, it is difficult for workers to limit them during welding. During the welding process, the electromagnetic shielding cover is prone to displacement, which affects the product quality.

[0007] Preferably, two sides of the upper shielding cover are respectively provided with sliding grooves, in which sliding blocks are slidably connected, and two sides of the lower shielding cover are respectively provided with clamping grooves.

[0008] The effect achieved by the above components is: sliding the slider downwards so that the slider is inserted into the slot, thereby improving the stability of the installation.

[0009] Preferably, two sides of the lower shielding cover are respectively fixedly connected with fixing plates, and sliding columns are slidably inserted on the fixing plates.

[0010] The effect achieved by the above components is: sliding the two sliding columns so that the sliding columns limit the sliding blocks, which can further improve the stability of the installation.

[0011] Preferably, a first spring is sleeved on the sliding column, one end of the first spring is fixedly connected to the fixing plate, and the other end of the first spring is fixedly connected to the sliding column.

[0012] The effect achieved by the above components is that when the sliding column limits the slider, the first spring is in a stretched state, so the rebound elastic force of the first spring acts on the sliding column, making the limiting of the slider by the sliding column more stable.

[0013] Preferably, sliding grooves are respectively provided on inner walls on both sides of the sliding groove, and sliding blocks are slidably connected in the sliding grooves, and the sliding blocks are fixedly connected to the sliding blocks.

[0014] The effect achieved by the above components is that the two sliding grooves slide in the sliding block to limit the position of the sliding block, thereby limiting the sliding block and preventing the sliding block from sliding out of the limit position of the sliding groove.

[0015] Preferably, a connection structure is provided on the lower shielding cover, and the connection structure is mainly composed of two connection blocks, the two connection blocks are respectively fixedly connected to the lower shielding cover and the upper shielding cover, and two connection grooves are opened on the magnetic core body.

[0016] The effects achieved by the above components are: by inserting the two connection blocks into the corresponding connection grooves, the magnetic core body can be limited and the magnetic core body can be easily disassembled.

[0017] Preferably, four rectangular grooves are formed in the lower shielding cover, and limit blocks are slidably connected in the rectangular grooves.

[0018] The effect achieved by the above components is: after the magnetic core body is connected to the lower shielding cover, four limit blocks are slid so that the limit blocks limit the magnetic core body, making the connection of the magnetic core body more stable.

[0019] Preferably, a second spring is fixedly connected to the inner wall of the rectangular groove, and one end of the second spring is fixedly connected to the limiting block.

[0020] The effect achieved by the above components is: when the magnetic core body is inserted into the lower shielding cover, the lower end of the magnetic core body will push the inclined surface of the limit block, causing the limit block to slide outward, squeezing the second spring to contract, and when the limit block slides to the outermost end, the limit block slides inward under the action of the rebound force of the second spring, and the planes of the four limit blocks limit the magnetic core body, further improving the stability of the connection.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are that, in the utility model, by setting the installation structure, the magnetic core body is placed in the lower shielding cover, and the four installation posts are respectively inserted into the corresponding installation grooves, so that the lower shielding cover and the upper shielding cover can be quickly installed together, and the slider is slid downward so that the slider is stuck in the slot, which can improve the stability of the installation, and the two sliding posts are slid so that the sliding posts limit the slider, which can further improve the stability of the installation. When the sliding post limits the slider, the first spring is in a stretched state, so the rebound elastic force of the first spring acts on the sliding post, so that the sliding post limits the slider more stably, and the two sliding grooves limit and slide in the sliding block, which can limit the slider and prevent the slider from sliding out of the limit of the sliding groove, thereby avoiding the current electromagnetic shielding covers are mostly installed by welding. Since many electromagnetic shielding covers are small in size, it is difficult for staff to limit them during welding. During the welding process, the electromagnetic shielding cover is prone to offset, which affects the product quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Embodiment 1, as Figure 1 As shown, a soft magnetic core with an electromagnetic shielding cover comprises a core body 1 , a lower shielding cover 2 is arranged on the core body 1 , and an upper shielding cover 3 is arranged on the lower shielding cover 2 .

[0028] Reference Figures 1 to 3 , the lower shielding cover 2 and the upper shielding cover 3 are provided with a mounting structure 4, the mounting structure 4 is mainly composed of four mounting posts 41, the four mounting posts 41 are fixedly connected to the upper shielding cover 3, the lower shielding cover 2 is provided with four mounting slots 42, the mounting posts 41 are adapted to the mounting slots 42 in size, the magnetic core body 1 is placed in the lower shielding cover 2, the four mounting posts 41 are respectively inserted into the corresponding mounting slots 42, the lower shielding cover 2 and the upper shielding cover 3 can be quickly installed together, thereby avoiding the current electromagnetic shielding covers are mostly installed by welding. Due to the small size of many electromagnetic shielding covers, it is difficult for staff to limit them during welding. During the welding process, the electromagnetic shielding covers are prone to offset, which affects the product quality. Slide grooves 43 are respectively provided on both sides of the upper shielding cover 3, and sliders 44 are slidably connected in the slide grooves 43. Card slots 45 are respectively provided on both sides of the lower shielding cover 2. The sliders 44 are slid downward so that the sliders 44 are stuck in the card slots 45. To improve the stability of installation, fixed plates 46 are fixedly connected to the two sides of the lower shielding cover 2, and sliding columns 47 are slidably inserted on the fixed plate 46. The two sliding columns 47 are slid so that the sliding columns 47 limit the slider 44, which can further improve the stability of installation. A first spring 48 is sleeved on the sliding column 47, one end of the first spring 48 is fixedly connected to the fixed plate 46, and the other end of the first spring 48 is fixedly connected to the sliding column 47. When the sliding column 47 limits the slider 44, the first spring 48 is in a stretched state, so the rebound elastic force of the first spring 48 acts on the sliding column 47, so that the limiting position of the slider 44 by the sliding column 47 is more stable. Sliding grooves 49 are respectively provided on the inner walls of the two sides of the slide groove 43, and sliding blocks 410 are slidably connected in the sliding groove 49. The sliding block 410 is fixedly connected to the slider 44. The two sliding grooves 49 limit and slide in the sliding block 410, which can limit the slider 44 and prevent the slider 44 from sliding out of the limit position of the slide groove 43.

[0029] Reference Figure 1 and Figure 4The lower shielding cover 2 is provided with a connection structure 5, which is mainly composed of two connection blocks 51. The two connection blocks 51 are respectively fixedly connected to the lower shielding cover 2 and the upper shielding cover 3. The magnetic core body 1 is provided with two connection grooves 52. The two connection blocks 51 are inserted into the corresponding connection grooves 52 to limit the magnetic core body 1 and facilitate the removal of the magnetic core body 1. Four rectangular grooves 53 are provided in the lower shielding cover 2. The rectangular grooves 53 are slidably connected with the limit blocks 54. After the magnetic core body 1 is connected to the lower shielding cover 2, the four limit blocks 54 are slid so that the limit blocks 54 are on the magnetic core. The main body 1 is limited, so that the connection of the magnetic core body 1 is more stable. A second spring 55 is fixedly connected to the inner wall of the rectangular groove 53, and one end of the second spring 55 is fixedly connected to the limit block 54. When the magnetic core body 1 is inserted into the lower shielding cover 2, the lower end of the magnetic core body 1 will push the inclined surface of the limit block 54, so that the limit block 54 slides outward, squeezing the second spring 55 to contract. When the limit block 54 slides to the outermost end, the limit block 54 slides inward under the action of the rebound force of the second spring 55. The planes of the four limit blocks 54 limit the magnetic core body 1, further improving the stability of the connection.

[0030] Working principle: place the magnetic core body 1 in the lower shielding cover 2, insert the four installation columns 41 into the corresponding installation grooves 42 respectively, and the lower shielding cover 2 and the upper shielding cover 3 can be quickly installed together, thereby avoiding the current electromagnetic shielding covers are mostly installed by welding. Since many electromagnetic shielding covers are small in size, it is difficult for workers to limit them during welding. During the welding process, the electromagnetic shielding cover is prone to offset, which affects the product quality. Slide the slider 44 downward so that the slider 44 is stuck in the slot 45, which can improve the stability of the installation. Slide the two sliding columns 47 so that the sliding column 47 limits the slider 44, which can further improve the stability of the installation. When the sliding column 47 limits the slider 44, the first spring 48 is in a stretched state, so the rebound elastic force of the first spring 48 acts on the sliding column 47, so that the sliding column 47 limits the slider 44. The limit is more stable, the two sliding grooves 49 slide in the sliding block 410 to limit the slider 44 and prevent the slider 44 from sliding out of the limit of the sliding groove 43. The two connecting blocks 51 are inserted into the corresponding connecting grooves 52 to limit the magnetic core body 1, and the magnetic core body 1 can be conveniently disassembled. After the magnetic core body 1 is connected to the lower shielding cover 2, the four limit blocks 54 are slid so that the limit blocks 54 limit the magnetic core body 1, making the connection of the magnetic core body 1 more stable. When the magnetic core body 1 is inserted into the lower shielding cover 2, the lower end of the magnetic core body 1 will push the inclined surface of the limit block 54, so that the limit block 54 slides outward, squeezing the second spring 55 to contract. When the limit block 54 slides to the outermost end, the limit block 54 slides inward under the action of the rebound elastic force of the second spring 55, and the planes of the four limit blocks 54 limit the magnetic core body 1, further improving the stability of the connection.
