Description

FIELD OF THE INVENTION

The present invention relates to a hot-swap fan terminal mount structure; and more particularly to a hot-swap fan terminal mount structure that can be manufactured at reduced cost and allows a terminal mounted thereon to have a self-alignment function. The present invention also relates to a fan using the above-described hot-swap fan terminal mount structure.

BACKGROUND OF THE INVENTION

Due to the progress in different technological fields, most of the currently available electronic products have largely increased functions. However, these functionally enhanced electronic products also produce more heat during operation thereof. The produced heat must be timely removed with proper means, so as to avoid lowered stability and performance or even burnout of the electronic products.
Presently, fans are the most common means for dissipating heat produced by electronic products. Generally, an electronic product is equipped with only one fan. However, for some advanced electronic systems that produce more heat during operation, they need more fans to thoroughly remove the produced heat and to increase the system stability. For example, when one of the fans is failed, the system can still maintain at stable working temperature by upgrading the heat dissipation efficiency of other remaining fans.
For this purpose, an advanced electronic system would usually use hot-swap fans. That is, any fan becoming failed during the operation of the system can be swapped for a new one through online manipulation without the need of shutting down the system. Therefore, the system can maintain continuous operation. For example, the hot-swap fans are particularly useful for a server of a computer system.
There are several hot-swap fan terminal structures currently available in the market. However, these hot-swap fan terminal structures are relatively complex in construction and include a large number of components to increase difficulty in assembling. In addition, with the existing hot-swap fan terminal structures, the conducting material thereof is exposed from a terminal mount and tends to become oxidized if the fan is not in use for a long time. The oxidized conducting material will inevitably cause problem in the electrical connection performance of the terminal.
In brief, the conventional fans and the terminal structures thereof have the following disadvantages: (1) requiring higher manufacturing cost; (2) not easy to assemble; (3) having narrow applications; and (4) tending to become damaged easily.
It is therefore tried by the inventor to work out a way for solving the problems and overcoming the disadvantages in the prior art fans and their terminal structures.
