Description

Technical Field

[0001] The utility model relates to the field of electronic connectors, in particular to a novel connector for a server fan. Background Art

[0002] In electronic devices, especially servers, power connectors play an important role in providing stable power to the system.

[0003] However, faced with increasingly severe market and technical challenges, traditional power connectors are facing multiple difficulties:

[0004] 1. Poor spatial adaptability: Existing power connector designs tend to be large, which runs counter to users' urgent need to save space and achieve device miniaturization. In many high-end application scenarios, such as high-efficiency data centers, bulky connectors not only take up valuable space, but also may interfere with air circulation and cause overheating.

[0005] 2. Insufficient current supply: As device power consumption increases, the demand for fast, high-current charging continues to rise. Conventional connectors on the market are mostly designed for lower currents. When encountering situations where large amounts of current need to be injected quickly, these accessories are often insufficient and cannot meet fast charging requirements while ensuring safety.

[0006] 3. Conflict between operational convenience and connection security: Under certain operating conditions, such as server maintenance and upgrades, it may be necessary to blindly plug and unplug the power connector without shutting down the device. Traditional power connector designs often fail to account for this special requirement and lack flexible floating docking capabilities, making it difficult to ensure both convenient and secure connections under non-ideal conditions.

[0007] Given this, the market urgently needs an innovative power connector design that is compact enough to accommodate space-constrained applications. It must also be able to handle high current loads, ensuring safe operation of devices under conditions like high-current fast charging. More importantly, the new design should allow for reliable electrical connection despite a certain degree of positional deviation, providing floating capability in both the X and Y directions to maintain efficient and safe power supply even during blind insertion and removal.

[0008] In this way, the birth of a new type of power connector will be the key to responding to the development of modern electronic devices. Its innovations will revolve around the miniaturization of the structure, the improvement of high current handling capabilities and enhanced plug-in tolerance, aiming to solve the limitations of traditional designs and meet more stringent market demands.
