DETAILED DESCRIPTION

[0019] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0020] according to Figure 1-5As shown, this embodiment proposes a connector with a shielding structure, including a positioning disk 1, a contact 2 and an assembly sleeve 3, the assembly sleeves 3 are symmetrically arranged on both sides of the positioning disk 1, the interior of the assembly sleeve 3 includes the contact 2, one end of the assembly sleeve 3 is provided with a clamping mechanism, and the outer side of the assembly sleeve 3 is fixed with a shielding magnetic ring 8 by a snap-fit ​​mechanism. When the connector is in use, the wires are first connected to the contacts 2, and then the assembly sleeve 3 is fixed to the positioning disk 1 by the clamping mechanism, wherein the assembly sleeve 3 wraps the contacts 2, and the shielding magnetic ring 8 is installed on the outer side of the assembly sleeve 3 by the snap-fit ​​mechanism, and the material of the shielding magnetic ring 8 has a shielding effect, which can increase the shielding capability of the connector.

[0021] The clamping mechanism includes a clamping block 10, a connecting block 11 and a clamping slot 12. One end of the assembly sleeve 3 is fixedly connected with a plurality of clamping blocks 10. Both sides of the positioning disk 1 are symmetrically provided with a plurality of connecting blocks 11. The connecting blocks 11 are provided with clamping slots 12. One end of the assembly sleeve 3 is clamped and connected with the connecting block 11 through the clamping block 10. The clamping block 10 at one end of the assembly sleeve 3 is attached to one side of the positioning disk 1 by bypassing the connecting block 11, and the clamping block 10 and the clamping slot 12 inside the connecting block 11 are on the same circumference. The assembly sleeve 3 is rotated to clamp the clamping block 10 into the inside of the clamping slot 12, so as to install the assembly sleeve 3 on one side of the positioning disk 1. When disassembly is required, the clamping block 10 only needs to be rotated out of the inside of the clamping slot 12.

[0022] The engaging mechanism includes an insert block 7 and a slot 9. A plurality of insert blocks 7 are provided on the outer side of the assembly sleeve 3, and a plurality of slots 9 are provided on the inner side of the shielding magnetic ring 8. The assembly sleeve 3 is engaged with the slots 9 through the insert blocks 7. One side of the shielding magnetic ring 8 is fitted and connected with one side of the positioning disk 1. The outer side of the shielding magnetic ring 8 is smaller than the distance between the connecting block 11 and the center of the positioning disk 1. The shielding magnetic ring 8 is made of magnetic material. The slot 9 inside the shielding magnetic ring 8 is aligned with the insert block 7 on the outer side of the assembly sleeve 3. The shielding magnetic ring 8 is pushed forward so that the slot 9 is engaged with the insert block 7, so as to fix the shielding magnetic ring 8 on the outer side of the assembly sleeve 3. The shielding magnetic ring 8 is usually made of magnetic material with high magnetic permeability, such as ferrite, nickel-zinc ferrite or cobalt ferrite. These materials can effectively absorb and disperse external magnetic field energy, thereby reducing electromagnetic interference.

[0023] One end of the assembly sleeve 3 is fixedly connected to a clamp 4, and a threaded surface 6 is provided on the outer side of the clamp 4. A tensioning sleeve 5 is threadedly connected to the outer side of the clamp 4 through the threaded surface 6. The tensioning sleeve 5 and one end of the clamp 4 are both provided with inwardly inclined chamfers, and a plurality of separation grooves are provided inside the clamp 4. A sealing ring 14 is provided at one end of the tensioning sleeve 5. When the wire is connected to the contact 2, it passes through the inside of the clamp 4, and the tensioning sleeve 5 is twisted to move in the direction of the assembly sleeve 3. The clamp 4 is squeezed by the inclined inner wall at one end of the tensioning sleeve 5, so that the clamp 4 clamps the outer wall of the wire, thereby limiting the wire, and making the connection between the wire and the contact 2 more stable. When it is necessary to release the limit on the wire, the tensioning sleeve 5 is twisted away from the assembly sleeve 3, and the sealing ring 14 can fill the gap between the tensioning sleeve 5 and the wire to ensure the sealing between the tensioning sleeve 5 and the wire.

[0024] A circular groove 15 is provided inside the contact 2, and a threaded hole 13 is provided on the top of the circular groove 15. A fastening bolt is connected to the internal thread of the threaded hole 13. The wire is inserted into the contact 2 through the circular groove 15, and then the fastening bolt is screwed into the threaded hole 13. The fastening bolt moves downward to clamp the wire to connect the wire to the contact 2. Since the two contacts 2 are connected to each other, the two wires can transmit electrical energy to each other.

[0025] The connector aligns the slot 9 inside the shielding magnetic ring 8 with the plug-in block 7 outside the assembly sleeve 3, and pushes the shielding magnetic ring 8 forward so that the slot 9 and the plug-in block 7 are engaged together, so as to fix the shielding magnetic ring 8 on the outside of the assembly sleeve 3. The shielding magnetic ring 8 is usually made of a magnetic material with high magnetic permeability, such as ferrite, nickel-zinc ferrite or cobalt ferrite. These materials can effectively absorb and disperse external magnetic field energy, thereby reducing electromagnetic interference.
