Description

Technical Field

[0001] This utility model relates to the technical field of modular electrical connectors, and in particular to a small, high-density, high-speed modular electrical connector. Background Technology

[0002] Electrical connectors are widely used components in electrical signal transmission. As their applications expand, simply transmitting ordinary electrical signals is no longer sufficient. Various electrical devices place increasingly stringent demands on connectors regarding functionality, size, waterproofing, dustproofing, and signal transmission quality. Signal transmission quality, in particular, has become a crucial indicator of connector quality in certain fields.

[0003] In traditional electrical connectors, the shielding structure design primarily considers the metal housing and tail accessories. When multiple electrical connectors are adjacent, the signal transmitted by each connector is affected by the electromagnetic signals generated by other connectors; and as the frequency of the signal transmitted by the connector increases, the influence of external electromagnetic signals on the signal transmitted by the connector increases the probability of electronic equipment failure.

[0025] 4. Contact unit. Detailed Implementation

[0026] like Figures 1 to 5 As shown, in this embodiment, the present invention includes a fixed frame 1, which has a plurality of connecting cavities 11. A shielding pin plate 12 for absorbing internal electromagnetic signals is slidably connected between two adjacent connecting cavities 11 in the vertical direction; a mounting cover 2, which is engaged with the locking mechanism of the fixed frame 1. Two sets of shielding rods 21 for absorbing electromagnetic signals for grounding are fixedly connected to the middle of the mounting cover 2. Each shielding rod 21 is disposed between two adjacent connecting cavities 11 in the horizontal direction; a shielding plate group 3, which is guided and connected to the mounting cover 2 and is used to connect to the grounding system to absorb electromagnetic signals; and a plurality of contact units 4, each of which is correspondingly disposed in a corresponding connecting cavity 11.

[0027] Specifically, the shielding pin plate 12, the shielding plate group 3, and the shielding rod 21 are all made of ferromagnetic materials with high magnetic permeability. The contact unit 4 forms a low-frequency magnetic field with high penetration during signal transmission. The shielding pin plate 12, the shielding plate group 3, and the shielding rod 21 can shunt the interference magnetic field, so that most of the magnetic flux is concentrated in the shielding body, thereby reducing the magnetic flux passing through the air and reducing the impact on the contact unit 4. By connecting to the grounding system, a low-impedance discharge path is provided, so that the electromagnetic interference current induced on the shielding pin plate 12, the shielding plate group 3, and the shielding rod 21 can flow into the ground quickly, avoiding the generation of potential difference, thereby reducing the risk of interference to the equipment or circuit caused by the shielding pin plate 12, the shielding plate group 3, and the shielding rod 21 themselves, and enhancing the shielding effect.

[0028] The fixed frame 1 adopts a connecting cavity 11 design, which enables each contact unit 4 to be quickly installed and fixed, allowing more transmission ports to be connected within a unit space. With the installation cover 2 with several locking blocks 13 for limiting and cooperating, modular installation is achieved, and the overall structure is compact. The electromagnetic signals transmitted by the contact unit 4 are absorbed between the two connecting cavities 11 through the shielding pin plate 12 and the shielding rod 21 structure. With the help of the shielding plate group 3, internal and external electromagnetic signals are blocked and shielded, reducing the impact on the contact unit 4 and improving the stability of signal transmission.

[0029] like Figures 4 to 5 As shown, in this embodiment, the outer wall of the fixing frame 1 is provided with a plurality of locking blocks 13, and the inner peripheral wall of the mounting cover 2 is provided with a corresponding locking groove 22 that is limited and matched with the corresponding locking block 13.

[0030] Specifically, the locking block 13 is provided with an inclined surface. During installation, the locking groove 22 is inserted along the inclined surface, and a locking block 33 is formed in the locking groove 22 to lock and limit the corresponding locking block 13, thus simplifying the installation process.

[0031] like Figure 4 As shown, in this embodiment, the middle part of the fixed frame 1 is symmetrically provided with guide grooves 14 corresponding to the guides of the corresponding shielding rods 21, and a slot 15 is provided between two adjacent connecting cavities 11 in the vertical direction for guiding and connecting the shielding pin plate 12.

[0032] Specifically, the guide groove 14 is provided with two horizontal connecting cavities 11 for guiding the installation of the shielding rod 21, improving installation efficiency. At the same time, it can absorb the electromagnetic interference transmitted laterally by the shielding baffle 212 of the shielding rod 21. The slot 15 is designed to facilitate the insertion and fixing of the shielding pin plate 12 during use.

[0033] like Figure 5 As shown, in this embodiment, the edge of the mounting cover 2 is provided with a plurality of positioning grooves 23 for guiding and connecting the shielding plate group 3.

[0034] like Figures 7 to 8 As shown, in this embodiment, the shielding plate assembly 3 includes a first connecting plate 31 and a second connecting plate 32. Both ends of the first connecting plate 31 are provided with locking blocks 33. The end of the second connecting plate 32 is provided with a corresponding locking slot 34 that engages with the corresponding locking block 33. One side of the first connecting plate 31 is provided with a first positioning block 35 that engages with the corresponding positioning groove 23. One side of the second connecting plate 32 is provided with a second connecting block 36 that engages with the corresponding positioning groove 23.

[0035] Specifically, the first connecting plate 31 and the second connecting plate 32 are made of metal plates spliced ​​together, which simplifies the molding process, makes mold cutting simple, and saves materials. The design of the clip 33 and the slot 34 only requires them to be snapped into the corresponding positions to complete the installation, thus improving the performance.

[0036] As shown in the figure Figure 5 As shown, in this embodiment, one side of the mounting cover 2 is formed with a first opening 24 through which the connection ends of the plurality of contact units 4 pass, and a second opening 25 through which the plurality of shielding pin plates 12 pass is provided below the plurality of first openings 24.

[0037] Specifically, the second opening 25 is located below the first opening 24. The second opening 25 allows the shielding pin plate 12 to pass through, and the first opening 24 allows the contact unit 4 to pass through, thereby improving the connection efficiency of the electrical connector.

[0038] like Figure 6 As shown, in this embodiment, the shielding rod 21 includes a grounding rod 211 that corresponds to and cooperates with the corresponding guide groove 14, and a shielding baffle 212 disposed between the two grounding rods 211 for absorbing electromagnetic signals. The shielding baffle 212 is connected to the shielding pin plate 12 of the corresponding height.

[0039] Specifically, both the grounding rod 211 and the shielding baffle 212 are made of metal. The grounding rod 211 is used to guide the wire through the guide groove 14 to improve installation efficiency, and at the same time connects to the grounding system so that the electromagnetic interference current can flow into the ground quickly.

[0040] The working principle of this utility model:

[0041] In use, multiple contact units 4 are individually installed in the connection cavity 11. The grounding rod 211 passes through the guide groove 14, the contact feet of the contact unit 4 pass through the corresponding first opening 24, the shielding pin plate 12 passes through the corresponding second opening 25, and the mounting frame locking groove 22 is inserted along the inclined surface. The locking groove 22 has a locking block 33 that is locked and limited by the corresponding locking block 13. The electromagnetic signals around each contact unit 4 are absorbed by the shielding pin plate 12, the shielding plate group 3 and the shielding rod 21, reducing the impact of internal and external electromagnetic signals on the transmission efficiency.

[0042] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
