Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically to an electrical connector with a shielding structure. Background Technology

[0002] Electrical connectors are primarily used to establish or disconnect electrical connections between different circuits. As electronic devices evolve towards higher performance and greater integration, electrical connectors not only need to meet the requirements of highly reliable physical connections, but also need to achieve stable signal transmission in complex electromagnetic environments.

[0003] However, many electrical connectors still have shortcomings in shielding performance. Due to incomplete contact points between the shielding shell and the connector base, shielding "blind spots" can easily form under high-frequency interference, allowing external electromagnetic interference to penetrate into the interior. Furthermore, the shielding effectiveness of the connector terminals can decrease due to vibration or thermal expansion and contraction. These problems not only lead to signal distortion and attenuation but can also cause electromagnetic interference between devices, affecting the overall performance and stability of the system.

[0004] Therefore, an electrical connector with a shielded structure is needed to solve the above-mentioned technical defects. Utility Model Content

[0005] The purpose of this invention is to provide an electrical connector with a shielding structure to solve the problem of reduced shielding effectiveness of electrical connectors mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electrical connector with a shielding structure, comprising a housing, an inner connector seat processed on the right side of the housing, an outer connector seat processed on the left side of the housing, an outer connector terminal installed in the outer connector seat, an inner connector terminal installed in the inner connector seat, a waterproof sleeve fitted onto the outer wall of the inner connector seat, a shielding ring welded at the connection between the waterproof sleeve and the inner connector seat, and an anti-rotation ring provided at the connection between the inner wall of the waterproof sleeve and the inner connector terminal.

[0007] As a further technical solution of this utility model, the inner connection terminal and the outer connection terminal are electrically connected.

[0008] As a further technical solution of this utility model, a dust cover is provided around the outside of the external connection terminal, and the edge of the dust cover protrudes from the external connection terminal.

[0009] As a further technical solution of this utility model, a reinforcing ring is provided at the connection between the external connecting terminal and the outer shell, and the reinforcing ring and the external connecting terminal form a concentric circle structure.

[0010] As a further technical solution of this utility model, the outer wall of the outer shell is machined with four sets of fixing holes, and the depth of the fixing holes is one-third of the thickness of the outer shell.

[0011] As a further technical solution of this utility model, the waterproof sleeve is made of insulating rubber, and the shielding ring is made of aluminum alloy.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the electrical connector with shielding structure not only achieves enhanced shielding performance and strong dustproof capability, but also achieves stable installation and high strength;

[0013] By incorporating an outer shell, shielding ring, waterproof sleeve, anti-rotation ring, and inner connector, the outer shell, shielding ring, and inner connector form a continuous conductive circuit, effectively shielding external electromagnetic interference and preventing signal leakage. During operation, the inner and outer connectors are electrically connected. The surrounding structure of the shielding ring isolates electromagnetic interference sources, ensuring the stability of signal transmission. The fixed design of the anti-rotation ring ensures a tight fit between the shielding ring and the inner connector, further enhancing shielding performance. This solves the problem of reduced shielding effectiveness of electrical connectors and improves anti-interference capabilities.

[0014] By incorporating a waterproof sleeve, a dustproof sleeve, and a reinforcing ring, the device features a dustproof sleeve on the outside of the external connection terminal. The edge of the dustproof sleeve protrudes from the external connection terminal, achieving a dustproof effect by covering the connection port. This prevents dust and moisture from entering the interior and avoids dust penetration due to loose material bonding. It solves the problem of insufficient dustproof capability of electrical connectors in outdoor environments and improves the applicability of electrical connectors in harsh environments.

[0015] The device is equipped with a housing, fixing holes, and reinforcing rings. Four sets of fixing holes are machined on the outer wall of the housing. The depth of each fixing hole is one-third of the thickness of the housing. The connector is fixed to the inside of the equipment by bolts. The evenly distributed spacing of the fixing holes can ensure the stability after installation, disperse the external impact force on the connector, ensure the shock resistance of the connector in high-frequency vibration environment, and improve the service life and safety of the connector.
