Description

Technical Field

[0001] This utility model relates to the field of M.2 connectors, and in particular to a signal-stabilized M.2 connector. Background Technology

[0002] Electronic connectors, also known as circuit connectors or electrical connectors, are conductor devices that bridge two conductors in a circuit, allowing current or signals to flow from one conductor to the other. An electronic connector is an electrical system that provides a separable interface for connecting two electronic systems. Simply put, a connector is a component used to complete the electrical connection between circuits or electronic devices; it is the bridge between the two. Examples include power plugs / sockets, IC sockets, telephone line plugs, etc.

[0003] Electronic connectors are widely used in various electrical circuits to connect or disconnect current or signals. This connection can be temporary and easily plugged in and out, or it can be a permanent connection between electrical equipment or wires. Electronic connectors are generally divided into two categories: female connectors and male connectors. Female connectors and male connectors are used in sets, and by mating the female connector and male connector, the circuit is made conductive to achieve data transmission.

[0004] The M.2 connector, or M.2 interface, is a next-generation interface standard tailored for Ultrabooks, replacing the original mSATA interface. Whether in terms of smaller size or higher transfer performance, M.2 far surpasses mSATA.

[0005] Current M.2 connectors generally consist of an insulating body, upper row of terminals, and lower row of terminals. The insulating body has multiple rear mounting slots at its rear end and multiple front mounting slots at its front end. The upper row of terminals is positioned in the rear mounting slots, and the lower row of terminals is positioned in the front mounting slots. The contact portions of the upper and lower rows of terminals extend to the upper and lower sides of the insertion cavity for mating and conductive connection with the male connector. This structure is relatively simple and, while it can basically achieve the function of connecting the connector's conductive circuit, it suffers from several drawbacks during use. The connector is prone to high-frequency resonance, which is detrimental to signal transmission. Furthermore, the connector's electromagnetic shielding performance is poor, making it susceptible to external electromagnetic interference (EMI) and signal transmission. It is also easily affected by high-frequency crosstalk during signal transmission, resulting in unstable signals, poor product quality, and a short lifespan. This causes inconvenience for users, makes the product less competitive, and fails to meet current needs. Therefore, it is necessary to research a new technical solution to improve current M.2 connectors. Utility Model Content
