1. Field of the Invention
The present invention relates to a fan, and in particular to a heat-dissipating fan applicable to an electronic product and the method for manufacturing the same.
2. Description of Prior Art
With regard to the existing compact electronic products, such as PDA or mobile phone, they are designed to be convenient to carry. As a result, the internal space thereof is small. If a fan is to be additionally provided therein to facilitate the heat-dissipating operation, the fan frame of the existing fan will impede the installation thereof. Especially, with regard to a plug connecting to a power source, an electric line is used to connect with the plug and the circuit board of the fan. Therefore, when such structure is to be installed in a small space, it will inevitably occupy too much space.
Moreover, the fan also plays an important role on a common personal computer or notebook computer. Since the heat dissipation is a critical problem in the operation of a computer, the failure of the fan may easily lower the operation efficiency of the computer or even stop the operation. However, the installation and detachment of the traditional fan of the computer is not convenient due to its structure, so that it is not easy for the user to replace with a new one by himself. Further, since the installation and detachment are not easy, it is inconvenient for the user to perform periodical cleaning. As a result, dirt may be adhered onto the fan to affect the magnitude of the generated wind. According to the above, the existing fan indeed has some drawbacks and problems.
In view of the above, the inventor proposes the present invention to overcome the above problems based on his expert experiences and deliberate researches.
The present invention is to provide a fan frame having embedded power source contact terminals and the method for manufacturing the same, by which the fan and the contact terminals connected to the power source can be directly disposed on the fan frame without any electric lines, thereby to reduce the installation space occupied by the fan and facilitate the installation and detachment thereof
The present invention provides a fan frame having embedded power source contact terminals, which comprises a fan frame and a pair of contact terminals for connecting to a power source. The pair of the contact terminals is embedded into the fan frame. Each contact terminal has a contact portion, and each contact portion is exposed to the outside of the fan frame.
In order to achieve the above objects, the present invention provides a method for manufacturing a fan frame having embedded power source contact terminals. When a fan frame is made by means of plastic injection molding, two contact terminals for connecting to the power source are formed in the fan frame by means of coating injection. Only the contact portions of the pair of contact terminals are exposed for conductive contact.
In order to make the Examiner to better understand the characteristics and technical contents of the present invention, a detailed description relating thereto will be made with reference to the accompanying drawings. However, it should be understood that the drawings are illustrative but not used to limit the scope of the present invention.
According to the above, in the present invention, when the fan frame 1 is made by means of plastic injection molding, two contact terminals 10 for connecting to a power source are formed in the fan frame 1 by means of coating injection. Only the contact portions 100 of the pair of contact terminals 10 are exposed to bring into conductive contact with a corresponding conductive seat 30 on the motherboard 3. The contact terminals 10 coated in the fan frame 1 are electrically connected with the circuit board in the fan frame 1, thereby to provide the stator of the fan with necessary electricity. In the first embodiment of the present invention, the contact terminal 10 is a male insert pin and located at a corner of one side of the fan frame 1. The corner is provided with insertion slots 11 for exposing the contact portions 100 of the contact terminals 10. The insertion slot 11 exactly mates with the piece-like conductive terminal 300 of the conductive seat 30, so that the conductive terminals 300 can be inserted into the insertion slots 11 to contact with the contact portions 100 of the contact terminals 10.

Further,
Finally,
Therefore, according to the present invention, the contact terminals for connecting the fan with the power source can be directly disposed on the fan frame without any electric lines, thereby to reduce the installation space occupied by the fan and facilitate the installation and detachment thereof
According to the above, the present invention indeed achieves the desired objects and overcomes the drawbacks of prior art. Further, it has novelty and inventive steps and thus conforms to the requirements for an invention patent.
Although the present invention has been described with reference to the foregoing preferred embodiments, it will be understood that the invention is not limited to the details thereof. Various equivalent variations and modifications can still be occurred to those skilled in this art in view of the teachings of the present invention. Thus, all such variations and equivalent modifications are also embraced within the scope of the invention as defined in the appended claims.
