[0002] As a high-voltage electrical equipment, high-voltage connectors are widely used in automobiles, power systems, industry and other fields. High-voltage connectors will generate large currents during operation. In order to avoid the influence of external electromagnetic fields on the signals generated by the connectors, electromagnetic shielding components are provided in conjunction with the connectors.

[0003] In the related art, the electromagnetic shielding component is an integrally molded shielding shell, which is electrically connected to the harness end of the connector through a number of elastic sheets.

[0055] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0056] The core of the present invention is to provide a shielding device. Through the arrangement of several shielding monomers, the shielding device can be freely assembled and designed to meet the shielding requirements of different products, reducing the processing and use costs. Through the close contact between the first contact part and the circumferential direction of the wire - end shielding case, the comprehensiveness, tightness and reliability of the contact are ensured, and shielding is carried out from all directions in the circumferential direction of the wire - end shielding case to ensure the shielding effect. Another core of the present invention is to provide a connector system including the above - mentioned shielding device.

[0057] The shielding device provided by the present invention includes a wire - end shielding case 1, a board - end shielding case and a current - guiding part 5. Please refer to Figures 1 - 6 、 Figure 20 。

[0058] Among them, the wire - end shielding case 1 is sleeved outside the shielded wire 4 to achieve a shielding effect and prevent the shielded wire 4 from being interfered by external electromagnetic fields during operation.

[0059] The board - end shielding case includes several shielding monomers. When it is necessary to form a certain angle between the board - end shielding case and the wire - end shielding case 1, the shape of the shielding monomers can be changed for flexible assembly, and the assembled board - end shielding case is then electrically connected to the wire - end shielding case 1.

[0060] It should be noted here that the wire-end shielding shell 1 and several shielding monomers are all independent structures. Compared with the integral manufacturing process, they have higher flexibility, lower manufacturing costs and process requirements, and are more suitable for the shielding requirements of different types of connectors. The different types here can be the size of the connector, the shape structure of the connector, etc.

[0061] Several shielding monomers surround to form a closed structure, and the closed structure ensures the shielding effect on the shielding wire 4. The specific closed structure is not limited to a circular structure, a square structure or an irregular structure.

[0062] The closed structure is provided with a first contact portion 21. The first contact portion 21 is the part for realizing the electrical connection between the wire-end shielding shell 1 and the board-end shielding shell, and can be an elastic protrusion, a spring piece, etc. When the wire-end shielding shell 1 contacts the first contact portion 21, a certain pre-tightening force can be provided to ensure the tight and reliable connection between the wire-end shielding shell 1 and the board-end shielding shell.

[0063] In one embodiment, a first contact portion 21 is provided on one of several shielding monomers, and the number of the first contact portions 21 can be set to two, corresponding to the input and output sides of a group of shielding wires 4.

[0064] In one embodiment, the first contact portion 21 is provided on two or more of several shielding monomers, corresponding to one group of shielding wires 4 or multiple groups of shielding wires 4, and is specifically designed in combination with the actual shielding requirements.

[0065] In a more specific embodiment, taking the first contact portion 21 as an elastic protrusion as an example, a plurality of closely arranged elastic protrusions are provided on the shielding monomer corresponding to the closed structure. The shape of the closely arranged here corresponds to the shape of the outer side of the wire-end shielding shell 1, and the shape of the inner side of the wire-end shielding shell 1 corresponds to the outer shape of the shielding wire 4.

[0066] Please refer to Figures 7 - 11 , the shape of the outer side of the wire-end shielding shell 1 in contact with the first contact portion 21 can be circular, or large semi-circular, or semi-circular, or square, etc., which is not limited here, as long as the shape of the first contact portion 21 corresponds to the outer shape of the wire-end shielding shell 1.

[0067] Taking Figure 7 as an example, the wire-end shielding shell 1 includes an inner wall surface 11, an outer wall surface 12, a first side surface 13, and a second side surface 14, wherein the inner wall surface 11 is in contact with the shielding wire 4, and the structure formed by the outer wall surface 12 and the first side surface 13 and the second side surface 14 is in close fit contact with the first contact portion 21.

[0068] With the first contact portion 21 being an elastic protrusion, the elastic protrusions are arranged circumferentially on the shielding monomer and are in close contact with the circumference of the wire-end shielding shell 1. When in contact, the elastic protrusions are compressed to provide a certain reverse pressing force, ensuring a tight and reliable fit between the wire-end shielding shell 1 and the first contact portion 21 and avoiding the occurrence of loose connections. In addition, multiple elastic protrusions are arranged circumferentially along the wire-end shielding shell 1 to ensure an all-round tight fit, thereby ensuring a good shielding effect.

[0069] The current guiding member 5 is electrically connected to the shielding monomer, and the external interference current received on the wire-end shielding shell 1 is led out through the board-end shielding shell and then led out to the ground or an insulator through the current guiding member 5 to prevent external magnetic field interference signals and protect the signals from being damaged or interfered with during the operation of the shielded wire.

[0070] In one embodiment, a plurality of shielding monomers are connected and surrounded to form a closed structure, and the current guiding member 5 is electrically connected to at least one shielding monomer to lead out the current.

[0071] The above-mentioned shielding device includes a wire-end shielding shell 1, a board-end shielding shell, and a current guiding member. The wire-end shielding shell 1 is sleeved outside the shielded wire 4. The board-end shielding shell includes a plurality of shielding monomers, and the plurality of shielding monomers surround to form a closed structure. The closed structure is provided with a first contact portion 21, and the first contact portion 21 is in close contact with the circumference of the wire-end shielding shell 1 to achieve electrical connection. The current outside the wire-end shielding shell 1 is conducted to the board-end shielding shell through the first contact portion 21. Further, the current on the board-end shielding shell is led out through the current guiding member 5. When the shielded wire 4 is operating normally, the external interference current can be led out through the wire-end shielding shell 1, the board-end shielding shell, and the current guiding member 5 to prevent external magnetic field interference signals and protect the signals from being damaged or interfered with during the operation of the shielded wire. The above-mentioned shielding device, through the arrangement of a plurality of shielding monomers, enables the shielding device to be freely assembled and designed to meet the shielding requirements of different products, reduces the processing and use costs, and through the close contact between the first contact portion and the circumference of the wire-end shielding shell, ensures the comprehensiveness, tightness, and reliability of the contact, and shields from all directions along the circumference of the wire-end shielding shell to ensure the shielding effect.

[0072] On the basis of the above-mentioned embodiment, the board-end shielding shell includes a female-end shielding shell 2 and a male-end shielding shell 3 electrically connected thereto, and at least one of the female-end shielding shell 2 and the male-end shielding shell 3 includes a plurality of shielding monomers.

[0073] Please refer to Figure 3 , the board-end shielding shell includes a female-end shielding shell 2 and a male-end shielding shell 3. The first contact portion 21 is provided on the female-end shielding shell 2. The external interference current passes through the wire-end shielding shell 1, the female-end shielding shell 2, the male-end shielding shell 3 and then to the current guiding member 5 to prevent external magnetic field interference signals and protect the signals from being damaged or interfered with during the operation of the shielded wire within the shielding device.

[0074] At least one of the female - end shielding case 2 and the male - end shielding case 3 includes a plurality of shielding units, that is, at least one of the female - end shielding case 2 and the male - end shielding case 3 is an assembled structure, which is convenient for flexible assembly of the board - end shielding case, improves the flexibility of the shielding device, reduces the processing cost and the use cost, and improves the applicability.

[0075] In a more preferred embodiment, both the female - end shielding case 2 and the male - end shielding case 3 include a plurality of shielding units. The number of shielding units included in the female - end shielding case 2 and the number of shielding units included in the male - end shielding case 3 can be the same for easy one - to - one docking and installation, or can be different to meet the integrity requirements of the board - end shielding case.

[0076] Take Figure 17 as an example. The male - end shielding case 3 includes two shielding units. There may be an overlapping area between the two shielding units for easy welding or riveting, or the two shielding units may not be connected and directly obtain support on the connector.

[0077] Take Figure 19 as an example. The male - end shielding case 3 includes four shielding units. There may be an overlapping area between the four shielding units for easy welding or riveting, or the four shielding units may not be connected and directly obtain support on the connector.

[0078] Take Figure 12 as an example. The male - end shielding case 3 includes three shielding units. Only the shielding unit forming the first contact part needs to be connected, and the other shielding units can be connected through the second connection point 215 or may not be connected.

[0079] The above - mentioned obtaining support on the connection actually means that there is a structure for limiting the shielding unit on the connector, and the shielding unit can be fixed by directly installing it on the limiting structure.

[0080] Based on any of the above - mentioned embodiments, the first contact part 21 is provided on the shielding unit corresponding to at least one side of the female - end shielding case 2;

[0081] The male - end shielding case 3 is provided with a circumferentially - arranged second contact part 31 and a third contact part 32.

[0082] Please refer to Figure 5 、 Figure 6 、 Figure 12, the first contact portion 21 is provided on the shielding monomer corresponding to at least one side portion of the female terminal shielding case 2. For example, if the female terminal shielding case 2 is a square structure with four side portions, the first contact portion 21 is provided on at least one side portion. In this case, two side portions can form a group of first contact portions 21, or two side portions form two groups of first contact portions 21, or one side portion forms two groups of first contact portions 21, which can be flexibly designed according to the structural form of the specific product applied.

[0083] Please refer to Figures 17 - 18 , the male terminal shielding case 3 is provided with a circumferentially arranged second contact portion 31 and a third contact portion 32. The second contact portion 31 and the third contact portion 32 can also be set in the structural form of elastic protrusions or elastic sheets. The specific structural forms of the three contact portions can be the same or different. The forms of the second contact portion 31 and the third contact portion 32 need to be combined with the structures of the female terminal shielding case 2 and the current guiding member 5 to ensure close fitting to conduct interference current and avoid interference with the normal operation of the shielded wire 4.

[0084] Through the arrangement of the circumferentially arranged second contact portion 31 and third contact portion 32, any azimuth in the circumferential direction of the male terminal shielding case 3 is in close contact with the female terminal shielding case 2 and the current guiding member 5, ensuring the all-round conduction of interference current and ensuring the shielding effect.

[0085] In a specific embodiment, neither the second contact portion 31 nor the third contact portion 32 is exposed, which plays a protective role while ensuring the safety of current conduction.

[0086] Based on any of the above embodiments, the shielding monomer includes:

In this embodiment, both the female terminal shielding case 2 and the male terminal shielding case 3 are split structures, which can be freely assembled and disassembled to meet the shielding requirements of different forms of products, reduce the processing cost, and improve flexibility and applicability.

[0091] Each common terminal shielding monomer 301 is provided with a second contact portion 31 and a third contact portion 32, so that the interference current on the female terminal shielding shell 2 is completely and comprehensively conducted to the current guiding member 5, ensuring the shielding effect.

[0092] The female terminal shielding monomer is electrically connected to the male terminal shielding monomer 301 to conduct the current on the first contact portion 21 out through the second contact portion 31 and the third contact portion 32 on the male terminal shielding monomer 301, ensuring the shielding effect.

No matter which way, a comprehensive shielding effect can be ensured.

[0094] It should be noted that each female terminal shielding monomer is riveted or welded to the female terminal closing cover 202 to ensure the comprehensiveness of the current conduction from the top to the current guiding member 5.
