Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a connector for a high-speed grounding shield group. Background Technology

[0002] Connectors are key components in electronic devices used to achieve electrical connections or signal transmissions, connecting two or more circuits, devices, or systems together through physical contact or non-contact methods.

[0003] Prior art (Chinese Patent Publication No. CN105337107B, Publication Date: 2018-01-16) discloses an electrical connector and a cable connector having the electrical connector. The electrical connector includes an insulating shell; a first module including a first insulating element and a set of first conductive terminals; a second module including a second insulating element and a set of second conductive terminals; two conductive retaining elements; a shielding plate including a plate body and two grounding portions, wherein the plate body spaced apart from the first and second conductive terminals, and the grounding portions contacting and electrically connecting with the conductive retaining elements; two conductive springs mounted on the outside of the insulating shell; and an outer shielding shell surrounding the conductive springs, the conductive retaining elements, and the outer periphery of the insulating shell. The cable connector includes the aforementioned electrical connector, a shielding shell mounted on the rear end of the electrical connector, an insulating outer shell covering the outer periphery of the shielding shell, and a cable electrically connected to the electrical connector. This invention can improve signal quality during high-speed data transmission.

[0004] Although existing technologies have shielding layers for shielding operations, they mostly use interference fits to ensure tight contact. However, during the injection molding process, due to the continuous increase in injection pressure, the position of the auxiliary pressing material is deformed due to the injection pressure on the mold workpiece, which can easily lead to gaps in the contact between the three components, causing an open circuit.

[0005] Therefore, we propose a connector for a high-speed grounding shield group to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a high-speed grounding shielded connector to solve the problem mentioned in the background art, where, during the injection molding process, due to the continuous increase in injection pressure, the auxiliary pressing position is deformed by the injection pressure on the mold workpiece, which easily leads to contact gaps between the three components and causes a circuit break.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a connector for a high-speed grounding shield group, including a housing, wherein a high-speed component for signal transmission is disposed inside the housing, and a shielding mechanism is disposed inside the housing, which is disposed on the side of the high-speed component to achieve full-band interference blocking.

[0008] Furthermore, a rear cover is provided on the rear side of the housing, and a connecting plate is provided inside the housing, with the high-speed component disposed on the connecting plate.

[0009] Furthermore, two sets of high-speed components are symmetrically arranged about the center point of the housing, and the high-speed components are arranged at equal intervals along the horizontal direction of the connecting plate.

[0010] Furthermore, the shielding mechanism includes an upper material layer, which is an electric field shielding layer and is made of high-conductivity copper material, thereby blocking external high-frequency electric field interference.

[0011] Furthermore, the shielding mechanism also includes a middle material layer, which is a magnetic field shielding and grounding transition layer, and is made of stainless steel. The middle material layer is used to shield low-frequency magnetic fields.

[0012] Furthermore, the shielding mechanism also includes a lower material layer, which is a mechanical protective layer and is made of high-conductivity copper material. The lower material layer is used to shield low-frequency magnetic fields.

[0013] Furthermore, the upper material layer and the lower material layer are located on the upper and lower sides of the middle material layer, respectively, and welding points are provided through the upper material layer, the middle material layer and the lower material layer to ensure that the three material layers will not separate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. It is equipped with three material layers: an upper material layer, a lower material layer, and a middle material layer. These three material layers are set on the side of the high-speed component. Through the cooperation of the upper material layer, the lower material layer, and the middle material layer, a full-band interference blocking effect can be formed, effectively protecting the high-speed component from the influence of external electromagnetic interference and ensuring the stability and reliability of signal transmission.

[0015] 2. The upper material layer is made of high-conductivity copper and serves as an electric field shielding layer. It can effectively block external high-frequency electric field interference and provide a safe electric field environment for high-speed components. The middle material layer is made of stainless steel and has both magnetic field shielding and grounding transition functions. It can effectively shield low-frequency magnetic fields and ensure good grounding performance, further improving the connector's anti-interference capability. The lower material layer is also made of high-conductivity copper and serves as a mechanical protection layer. It can not only shield low-frequency magnetic fields but also provide additional mechanical protection for the entire connector, enhancing its durability and reliability.

[0016] 3. The upper, middle, and lower material layers are tightly connected by welding points to ensure that the three layers will not separate during use, thus guaranteeing the durability and stability of the shielding effect. The tight fit between the components effectively solves the electromagnetic interference problem existing in the prior art, improves the quality and stability of signal transmission, and is suitable for occasions with high requirements for the electromagnetic environment.

[0017] 4. The high-speed components are arranged symmetrically above and below the center point of the housing and at equal intervals laterally, which makes the signal transmission more balanced and stable. It avoids signal interference or attenuation problems caused by unreasonable component layout, and improves the overall working performance of the connector. The mating arrangement between the back cover and the housing provides good protection for the internal components of the connector, preventing external dust, moisture and other impurities from entering, ensuring the cleanliness and dryness of the internal environment of the connector, and helping to extend the service life of the connector.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: As Figures 1-4The technical solution shown is provided by the present utility model as follows: A connector for a high-speed grounding shield group is disclosed, wherein a high-speed component 8 for signal transmission is disposed inside the housing 1, a rear cover 2 is disposed on the rear side of the housing 1, and a connecting plate 3 is disposed inside the housing 1. The high-speed component 8 is disposed on the connecting plate 3. Two sets of high-speed components 8 are symmetrically arranged about the center point of the housing 1, and the high-speed components 8 are arranged at equal intervals along the horizontal direction of the connecting plate 3.

[0022] The high-speed component 8 adopts a symmetrical vertical and horizontal spacing arrangement around the center point of the housing 1. The back cover 2 and the housing 1 are precisely mated together. The two are tightly connected by a specific snap-fit ​​structure or sealing process, which builds a solid protective barrier for the internal components of the connector. It can effectively block the intrusion of external dust, moisture and other impurities, keep the internal environment of the connector clean and dry, reduce the risk of short circuits, corrosion and other failures caused by impurities, extend the service life of the connector and reduce maintenance costs.

[0023] The device employs a three-layer material structure: an upper material layer 4, a lower material layer 5, and a middle material layer 6. All three layers are positioned along the sides of the high-speed component 8. Through the coordinated operation of these three layers, interference blocking across the entire frequency band is achieved, thus constructing a reliable electromagnetic shield for the high-speed component 8. This effectively resists external electromagnetic interference and ensures the stability and reliability of signal transmission. The upper material layer 4 is made of high-conductivity copper and serves as an electric field shielding layer. Its superior conductivity efficiently blocks external high-frequency electric field interference, creating a safe and stable electric field for the high-speed component 8. In terms of environment, the middle material layer 6 is made of stainless steel and has the dual functions of magnetic field shielding and grounding transition. On the one hand, it can effectively shield low-frequency magnetic fields and reduce the impact of low-frequency magnetic fields on high-speed components 8; on the other hand, it can ensure good grounding performance, further optimize electromagnetic compatibility, and significantly improve the connector's anti-interference ability. The lower material layer 5 is also made of high-conductivity copper and mainly plays the role of mechanical protection layer. It can not only work with the upper and middle material layers to shield low-frequency magnetic fields, but also provide additional mechanical protection for the entire connector, enhance the structural strength of the connector, and thus improve its durability and reliability.

[0025] The upper material layer 4, the middle material layer 6, and the lower material layer 5 are tightly connected via welding point 7. This connection method ensures that the three layers will not separate during long-term use. The stable connection structure guarantees the durability and stability of the shielding effect. The close cooperation between the components forms an efficient and reliable electromagnetic protection system, improving the quality and stability of signal transmission. It is especially suitable for applications with stringent electromagnetic environment requirements, such as the operating environment of high-precision electronic equipment and electromagnetically sensitive areas.
