Description

Technical Field

[0001] This utility model relates to the field of wire connector technology, and in particular to a wire connector with electromagnetic shielding and anti-mismating structure. Background Technology

[0002] With the trend of electronic devices moving towards high integration and high transmission rates, wire connectors, as the core interface for signal and energy transmission, directly determine the stability and reliability of equipment operation. From the perspective of functional requirements, on the one hand, the dense circuit modules inside electronic systems and the complex external electromagnetic environment generate a large amount of electromagnetic noise. If the connector lacks effective electromagnetic shielding capabilities, noise can easily invade the transmission link through the interface, leading to signal distortion, data transmission errors, and even equipment failure. Therefore, electromagnetic shielding has become a key requirement to ensure the integrity of connector signals. Its core is to block the radiation and coupling of electromagnetic energy through specific structures or materials. On the other hand, in multi-interface devices, connectors with different functions often have similar shapes and interface specifications. During manual insertion and removal operations, misinsertion is very likely to occur. Misinsertion can not only cause physical damage to the interface, but also burn out the internal circuit due to voltage and signal type mismatch, resulting in serious economic losses. Therefore, anti-misinsertion structures have become a necessary design to avoid operational errors and protect equipment safety.

[0003] Against this backdrop, wire connectors with electromagnetic shielding and anti-mismating structures have emerged. These are defined as connector assemblies that integrate electromagnetic shielding components and anti-mismating mechanical structures to achieve stable connections between wires and devices, while also providing electromagnetic interference resistance and preventing incorrect insertion / removal. Early connectors were prone to gaps at the junction of the electromagnetic shielding layer, the housing, and the wire, leading to decreased shielding effectiveness. Especially after frequent insertion and removal, the shielding layer was prone to loosening and damage. Anti-mismating structures, due to their simple design, still posed a risk of mismating in complex operating environments. Furthermore, some anti-mismating structures were poorly designed, resulting in excessive insertion and removal forces, affecting operational convenience. To address these shortcomings, existing technologies achieve sealing by enhancing the mechanical fit between the shielding layer and the connector housing and wire, and by using irregularly shaped interfaces to prevent the insertion of non-compatible connectors. However, the durability of the electromagnetic shielding structure is insufficient, and assembly deviations can easily lead to uneven crimping of the shielding layer, resulting in localized electromagnetic leakage and low practicality. Utility Model Content

The inner wall of the insulating shell 201 is fixedly connected to the outer wall of the male connector 5. An interference shell 202 is fixedly connected to the outer wall of the insulating shell 201. The interference shell 202 is a high-conductivity metal shell, such as a copper alloy, and has a closed ring structure. It can wrap the insulating shell 201 and part of the male connector 5, and block the intrusion of external electromagnetic waves through a reflection mechanism, while suppressing internal signal radiation. An elastic conductive component 203 is provided on the inner wall of the interference shell 202. A locking component 304 is provided on the left side of the square shell 1. The elastic conductive component 203 includes a coarse rubber ring 2031. The outer wall of the coarse rubber ring 2031 is fixedly connected to the inner wall of the interference shell 202. Multiple fine rubber rings 2032 are fixedly connected to the inner wall of the interference shell 202. The fine rubber rings 2032 are made of the same material as the coarse rubber ring 2031 and are spaced apart. They can further fill the tiny gaps not covered by the coarse rubber ring 2031, forming a multi-layer seal and enhancing the shielding effect. A locking component 204 is provided on the outer wall of the interference shell 202. Specifically, the square shell 1 serves as the external foundation support component of the connector, housing and protecting the internal core component, the female connector 6. It also provides a fixed carrier for the absorption mesh 4, ensuring the stability of the overall structure. The absorption mesh 4, made of high magnetic permeability or high electrical conductivity metal braided material, is fixedly connected to the outer wall of the square shell 1. Its core function is to initially reflect and absorb some electromagnetic waves upon contact, reducing the electromagnetic load on the subsequent shielding structure and laying the foundation for the overall shielding effect.

Mechanical locking is achieved after the male connector 5 and female connector 6 are correctly connected. The elastic conductive component 203 includes a coarse rubber ring 2031. The outer wall of the coarse rubber ring 2031 is fixedly connected to the inner wall of the interference shell 202. The coarse rubber ring 2031 contains conductive particles and has a large cross-sectional size, which can cover the main gaps in the inner wall of the interference shell 202. When it is squeezed by the interference shell 202 and the insulating shell 201, it deforms, causing the conductive particles to contact and form a conductive path, blocking electromagnetic leakage. The outer wall of the interference shell 202 is provided with a locking component 204, which is used to fix the interference shell 202 to the external structure to prevent the interference shell 202 from loosening and affecting the shielding effectiveness.

Specifically, the locking assembly 304 includes a U-shaped plate 3041, the right side of which is fixedly connected to the left side of the square shell 1.

By rotating the screw 2052, the square plate 2042 can be moved closer to the square shell 1 until the annular plate 2041 drives the interference shell 202 to fit tightly against the square shell 1, eliminating assembly gaps.

[0022] Working principle: When electromagnetic waves come into contact with the absorption mesh 4, a portion of the electromagnetic waves are reflected by the absorption mesh 4. Subsequently, the electromagnetic waves are interfered with and shielded by the insulating shell 201 and the interference shell 202. The elastic conductive component 203 is located between the insulating shell 201 and the interference shell 202. When it is squeezed, the rubber deforms and the conductive particles come into contact with each other to form a conductive path, ensuring the continuity of the overall conductivity of the shielding shell after assembly and reducing electromagnetic leakage. Then, by tightening the screw 2052, the shielding effect is enhanced and the practicality is improved. When connecting the male connector 5 and the female connector 6, the positioning component 303 first guides the connection, and then the corresponding convex ring 301 enters the corresponding groove 302, achieving the effect of preventing incorrect insertion. By rotating the rotating plate 3042, the rotating plate 3042 is engaged with the locking plate 3043, and the guide post 3051 is inserted into the corresponding guide hole 3052, thereby locking the male connector 5 and the female connector 6, preventing loosening, and enhancing practicality.
