Description

Technical Field

[0001] The utility model relates to the technical field of multi-pole magnetic rings, in particular to a ferrite multi-pole magnetic ring. Background Technique

[0002] Ferrite magnetic rings mainly include nickel-zinc ferrite magnetic rings and manganese-zinc ferrite magnetic rings, and these two types of magnetic rings have strict distinctions for different frequencies of use. Nickel-zinc ferrite magnetic rings are suitable for suppressing electromagnetic interference in the high-frequency band; manganese-zinc ferrite magnetic rings are suitable for suppressing electromagnetic interference in the low-frequency band.

[0003] When the existing ferrite multi-pole magnetic rings are in use, they are usually directly sleeved on the cable through the provided mounting holes, which makes the mounting holes of the ferrite multi-pole magnetic rings need to be customized according to the diameter size of the cable, resulting in poor applicability of the ferrite multi-pole magnetic rings. How to design a ferrite multi-pole magnetic ring that can be suitable for cables with various diameter sizes has become a problem that needs to be urgently solved by the staff in this field. In this regard, we propose a ferrite multi-pole magnetic ring. Content of the Utility Model

[0004] The purpose of the utility model is to provide a ferrite multi-pole magnetic ring to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A ferrite multi-pole magnetic ring, comprising:

[0006] A multi-pole magnetic ring body, a socket hole is provided on the multi-pole magnetic ring body, two symmetrically arranged arc-shaped fixing plates are provided in the socket hole, a pair of fixing rods are fixedly bonded to the opposite side walls of the two arc-shaped fixing plates, a sliding rod is provided on the fixing rod, two arc-shaped clamping plates are provided between the two arc-shaped fixing plates, the two arc-shaped clamping plates are respectively fixedly bonded to two pairs of sliding rods, a bidirectional screw rod is rotatably installed on each of the two pairs of fixing rods, two moving blocks are threadedly connected to the bidirectional screw rod, a connecting rod is rotatably installed on the moving block, and the end of the connecting rod away from the moving block is rotatably installed on the arc-shaped clamping plate.

[0007] Preferably, the two arc-shaped fixing plates are fixedly welded to the inner wall of the socket hole.

[0008] Preferably, a chute is opened on the fixing rod, a slider is fixedly bonded to the sliding rod, and the slider is slidably connected in the chute.

[0009] Preferably, one end of each of the two bidirectional screw rods is fixedly provided with a screwing seat, and a cross groove is opened on the screwing seat.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] Through the cooperation of components such as the arc-shaped fixing plate, fixed rod, sliding rod, bidirectional lead screw, arc-shaped clamping plate, and moving block installed in the socket hole of the multi-pole magnetic ring body, when installing the multi-pole magnetic ring body, the cable can be inserted into the socket hole. By rotating the screwing seat with an auxiliary tool, the bidirectional lead screw is driven to rotate. When the bidirectional lead screw rotates, the two moving blocks on the bidirectional lead screw can move towards or away from each other, thereby driving the connecting rod to flip and driving the arc-shaped clamping plate to move, so that the two arc-shaped clamping plates can tightly clamp on the cable, thus fixing the multi-pole magnetic ring body on the cable. The arc-shaped clamping plate can be adjusted, so as to facilitate the installation of the multi-pole magnetic ring body on various cables with different sizes, greatly improving the applicability of the multi-pole magnetic ring.

Detailed Embodiment

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-4 , the present utility model provides a technical solution: a ferrite multi-pole magnetic ring, including:

[0019] Multi-pole magnetic ring body 1, on which there is a socket hole 2, and in the socket hole 2 there are two symmetrically arranged arc-shaped fixing plates 3. On the opposite side walls of the two arc-shaped fixing plates 3, a pair of fixing rods 4 are fixedly adhered respectively. On the fixing rods 4, there are sliding rods 5. Between the two arc-shaped fixing plates 3, there are two arc-shaped clamping plates 6. The two arc-shaped clamping plates 6 are fixedly adhered to the two pairs of sliding rods 5 respectively. On both pairs of fixing rods 4, there are rotatably installed bidirectional lead screws 7. On the bidirectional lead screws 7, there are threadedly connected two moving blocks 8. On the moving blocks 8, there are rotatably installed connecting rods 9. The end of the connecting rod 9 away from the moving block 8 is rotatably installed on the arc-shaped clamping plate 6.

[0020] Both of the two arc-shaped fixing plates 3 are fixedly welded on the inner wall of the socket hole 2.

[0021] On the fixing rod 4, there is a chute 10. On the sliding rod 5, there is a slider 11 fixedly adhered. The slider 11 is slidably connected in the chute 10. Through the sliding fit of the set slider 11 and chute 10, it is convenient to guide when the sliding rod 5 slides.

[0022] On one end of both of the two bidirectional lead screws 7, there is a rotatable seat 12 fixedly installed. On the rotatable seat 12, there is a cross slot 13. The cross slot 12 can use auxiliary tools such as a screwdriver to rotate the rotatable seat 12, drive the bidirectional lead screw 7 to rotate, and realize the adjustment of the arc-shaped clamping plate 6.

[0023] Working principle: When this utility model is in use, the cable can be inserted into the socket hole 2. By using an auxiliary tool to rotate the rotatable seat 12, the bidirectional lead screw 7 is driven to rotate. When the bidirectional lead screw 7 rotates, the two moving blocks 8 on the bidirectional lead screw 7 can move towards or away from each other, thereby driving the connecting rod 9 to flip and driving the arc-shaped clamping plate 6 to move, so that the two arc-shaped clamping plates 6 can tightly clamp the cable, and thus fix the multi-pole magnetic ring body 1 on the cable.
