Description

Technical Field

[0001] This utility model relates to a ferrite core connector, specifically an E-type ferrite core connector, belonging to the field of magnetic core technology. Background Technology

[0002] The characteristics of soft magnetic ferrite are: low saturation magnetic flux density, low permeability, low Curie temperature, low mid-to-high frequency loss, and low cost. It is widely used in filters, tuned filters, load coils, impedance matching transformers, proximity sensors, transformers, etc. Moreover, there are many types of soft magnetic ferrite cores, including E, U, EC, square and round, among which E-type soft magnetic ferrite is very widely used and convenient.

[0003] Currently, most E-type ferrite cores are installed by connecting the bottom terminal block with bolts. The installation process is relatively cumbersome and can only fix the bottom of the E-type ferrite core. This causes the top of the E-type ferrite core to wobble during use, which can lead to poor contact.

[0004] Therefore, an E-type ferrite core connector is proposed here. Utility Model Content

[0005] This invention proposes an E-type ferrite core mounting bracket, which simultaneously fixes the side and top of the core using a side positioning bracket and a top positioning bracket, enabling rapid installation of the E-type ferrite core.

[0006] This utility model is achieved through the following technical solution: an E-type ferrite core mounting base, including a support frame, a limit frame fixed on the top surface of the support frame, a first transmission hole and a second transmission hole respectively opened on the top surface of the support frame on both sides of the limit frame, a connecting plate slidably connected to one side of the support frame, and a mounting assembly for fixing the magnetic core provided between the connecting plate and the support frame, the mounting assembly including a first transmission block fixed on the upper surface of the connecting plate, a top positioning frame rotatably connected to the top of the first transmission block, the top of the top positioning frame slidably passing through the second transmission hole and threaded with a second bolt, a second transmission block fixed on the upper surface of the connecting plate, a pull rod rotatably connected to the top of the second transmission block, a side positioning frame rotatably connected to the top of the pull rod, and a first bolt threadedly connected to the top of the side positioning frame.

[0007] Furthermore, a transmission groove is provided on one side of the top positioning frame, and a second positioning shaft fixed to one side of the support frame is slidably connected inside the transmission groove.

[0008] Furthermore, a first positioning shaft is fixed to one side of the support frame, and the first positioning shaft is rotatably sleeved on the middle section of the side positioning frame.

[0009] A limiting groove is provided on one side of the support frame, a movable plate is fixed on one side of the connecting plate, and a positioning component for moving the movable plate is provided on one side of the support frame.

[0010] Furthermore, the top end of the transmission rod slides through the top of the support frame and extends to the outside of the support frame, and a set of anti-slip grooves are provided at the top end of the transmission rod.

This causes the second bolt to fix the top of the E-type ferrite core. The second transmission block and the pull rod drive the side positioning frame to rotate around the first positioning shaft, bringing the first bolt into contact with the side of the E-type ferrite core, thus facilitating the quick installation of the E-type ferrite core.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0026] Please see Figures 1-4 The present invention proposes the following implementation scheme: an E-type ferrite core mounting base, including a support frame 1, a limiting frame 2 fixed on the top surface of the support frame 1, a first transmission hole 7 and a second transmission hole 8 respectively opened on the top surface of the support frame 1 on both sides of the limiting frame 2, a connecting plate 4 slidably connected to one side of the support frame 1, a mounting assembly 3 for fixing the magnetic core is provided between the connecting plate 4 and the support frame 1, the mounting assembly 3 includes a first transmission block 30 fixed on the upper surface of the connecting plate 4, a top positioning frame 36 rotatably connected to the top of the first transmission block 30, the top of the top positioning frame 36 slidably passing through the second transmission hole 8 and threadedly fitted with a second bolt 37, a second transmission block 35 fixed on the upper surface of the connecting plate 4, a pull rod 34 rotatably connected to the top of the second transmission block 35, a side positioning frame 31 rotatably connected to the top of the pull rod 34, and a first bolt 32 threadedly fitted to the top of the side positioning frame 31.

[0027] In the above scheme, a washer is provided at the end of the first bolt 32 and the second bolt 37 that is close to the magnetic core.

[0028] Please refer to this carefully. Figure 4 A transmission groove 38 is provided on one side of the top positioning frame 36, and a second positioning shaft 39 fixed to one side of the support frame 1 is slidably connected inside the transmission groove 38.

[0029] A first positioning shaft 33 is fixed on one side of the support frame 1, and the first positioning shaft 33 is rotatably sleeved on the middle section of the side positioning frame 31.

[0030] In the above scheme, the connecting plate 4 is moved together by the moving plate 5, and the first transmission block 30 and the second transmission block 35 are moved at the same time. The first transmission block 30 drives the top positioning frame 36 to slide the surface of the second positioning shaft 39, so that the top positioning frame 36 can move obliquely downward closer to the limiting frame 2. The top of the E-type ferrite core is fixed by the second bolt 37. The side positioning frame 31 is rotated around the first positioning shaft 33 by the second transmission block 35 and the pull rod 34, and the first bolt 32 contacts the side of the E-type ferrite core, and the side of the E-type ferrite core is fixed in conjunction with the limiting frame 2.

[0031] Please refer to this carefully. Figure 2 , Figure 3 and Figure 4 A limiting groove 9 is provided on one side of the support frame 1, a movable plate 5 is fixed on one side of the connecting plate 4, and a positioning component 6 is provided on one side of the support frame 1 to drive the movable plate 5 to move. The positioning component 6 includes a transmission rod 61 fixed on the upper surface of the movable plate 5, and positioning blocks 63 are fixed on both sides of the transmission rod 61. A first connecting block 64 is rotatably connected to one side of the positioning block 63, and a telescopic rod 65 is fixed to one side of the first connecting block 64. A connecting sleeve 68 is slidably sleeved on the end of the telescopic rod 65 away from the first connecting block 64, and a second connecting block 67 is fixed to the end of the connecting sleeve 68 away from the telescopic rod 65, and the second connecting block 67 is rotatably connected to one side of the support frame 1.

[0032] Please refer to this carefully. Figure 3 The top end of the transmission rod 61 slides through the top of the support frame 1 and extends to the outside of the support frame 1. A set of anti-slip grooves 62 are provided at the top end of the transmission rod 61.

[0033] A compression spring 66 is fixed between the first connecting block 64 and the connecting sleeve 68, and the compression spring 66 is sleeved on the outside of the telescopic rod 65.

[0034] In the above scheme, the transmission rod 61 is moved downward, and the moving plate 5 slides inside the limiting groove 9. The compression spring 66 pushes the first connecting block 64, and the telescopic rod 65 slides inside the connecting sleeve 68. When the telescopic rod 65 and the connecting sleeve 68 tilt downward, the position of the transmission rod 61 can be supported.

[0035] Please refer to this carefully. Figure 4 The limiting groove 9 has a fixed limiting shaft 51 inside, and the limiting shaft 51 is slidably sleeved inside the moving plate 5.

[0036] In use, the support frame 1 is mounted on the surface of the circuit board. The E-type ferrite core is placed on the top surface of the support frame 1 and initially fixed by the limiting frame 2. Then, the transmission rod 61 is moved downward, causing the moving plate 5 to slide inside the limiting groove 9. The compression spring 66 pushes the first connecting block 64, causing the telescopic rod 65 to slide inside the connecting sleeve 68. When the telescopic rod 65 and the connecting sleeve 68 tilt downward, the position of the transmission rod 61 is supported. The moving plate 5 moves the connecting plate 4 together. The first transmission block 30 and the second transmission block 35 move simultaneously. The first transmission block 30 drives the top positioning frame 36 to slide the surface of the second positioning shaft 39, which allows the top positioning frame 36 to move obliquely downward toward the limit frame 2. This causes the second bolt 37 to fix the top of the E-type ferrite core. The second transmission block 35 and the pull rod 34 drive the side positioning frame 31 to rotate around the first positioning shaft 33, and cause the first bolt 32 to contact the side of the E-type ferrite core, so as to facilitate the quick installation of the E-type ferrite core.
