Abstract

A heat dissipation connector of the invention is not only an externally auxiliary heat dissipation device used beside relative electric appliance such as PC or the like to do heat dissipated away from relative electric appliance, but also an externally auxiliary connector to provide one or more USB ports to be used for other electric appliance.

A heat dissipation connector of the invention is provided with at least two USB ports, one USB port can get electric power of DC 5V, supplied from an USB port of relative electric appliance such as PC, to drive DC fans to rotate for heat dissipation. Therefore, no AC/DC converters or DC/DC converters are needed.

Claims

1. A heat dissipation connector with at least two USB ports comprising:

a front cover, which is a rectangle cover with four outwardly extended edges and at least one air outlet openings on its rectangle face;

a back cover 1, which is relative to said front cover and is a rectangle cover with four outwardly extended edges and with at least one air inlet openings relative to said air outlet openings of said front cover, and which is provided with four positioning strips formed at each corner of its rectangle face used as a spacer respectively;

a pair of U-shaped supports, which are respectively positioned against two spaced positioning strips of said back cover to capably make said front cover and said back cover stood up securely;

at least one DC fans, which air outlet is positioned relative to said air outlet openings of said front cover and air inlet is positioned relative to said air inlet openings of said back cover;

at least two USB ports , which are installed on lateral end of both said front cover and said back cover, and one USB ports used to supply power with DC 5V to said DC fans by an USB cable; and

an electronic control circuit boards, which is installed inside said back cover to control one USB port to get electric power of DC 5V supplied from relative electric appliance to drive DC fans to rotate for heat dissipation, and to control the other USB port to provide a function for transmission speeds of 12 megabits per second and supply DC 5V for other use.

2. The heat dissipation connector according to claim 1, wherein said front cover is provided with two openings, said back cover is provided with two relative openings and two DC fans are relatively positioned between two opposite openings of said front cover and said back cover.

3. The heat dissipation connector according to claim 1 or claim 2, further comprises a DC 12V socket and a switch, which said DC 12V socket can get electric power of DC 12V supplied from cigarette lighter of a motor vehicle when said switch is switched on and converted as DC 5V under control of said electronic control circuit boards.

4. The heat dissipation connector according to claim 3, wherein four supporting blocks further formed on each corner of the rectangle face of said front cover
