DETAILED DESCRIPTION OF THE INVENTION

[0021] Firstly, please refer to FIGS. 1 to 2. The invention is based on an adapter 1 with a heat dissipation fan 2, the adapter 1 is applied in high-current workplaces. One end of the adapter 1 is provided with a plug 11, and another end of the adapter 1 is provided with a socket 12, the plug 11 and the socket 12 are electrically connected, for example, a material with good conductivity is used for connection. A main structure on which the invention is based is that the heat dissipation fan 2 is disposed on one side or two sides of the adapter 1 at the same time. The heat dissipation fan 2 is activated by a small amount of electric power from the adapter 1. When the adapter 1 is connected to electric power, the heat dissipation fan 2 is capable of drawing/sending air from or to the adapter 1 internally so as to reduce heat inside the adapter 1 and achieve a function of heat dissipation. Therefore, the adaptor 1 is capable of reducing heat generation and prolonging service life, suitable for using in work locations where high electric current is adopted, and capable of maintaining stability and safety in work. In addition, the adapter 1 can be used in series connection, that is, for ordinary plugs and sockets that would otherwise generate high heat, a structure of the adapter 1 can be connected in series between a plug and a socket to be capable of discharging heat by the heat dissipation fan 2 to achieve efficient heat dissipation.

[0022] The heat dissipation fan 2 can be a DC electric fan or an AC electric fan. For the heat dissipation fan 2 using DC power, a conventional rectifier can be disposed between the adapter 1 and the heat dissipation fan 2, so that an AC power supply connected to the adapter 1 after being rectified can be used by the heat dissipation fan 2. In addition, to match and cooperate with the structure of the adapter 1, one end of the adapter 1 can be directly provided with a power input line, and another end of the adapter 1 is provided with the socket 12, the input line is used to import electric power and the socket 12 is used to output electric power. In this way, the adapter 1 forms a power socket design, which can be used for plugging in other electrical appliances. By the same token, one end of the adaptor 1 can also be provided with the plug 11, and the other end of the adapter 1 is provided with an output line. The output line is used to output electric current to other electrical appliances. Thereby, the adaptor 1 can directly become a power plug for an electrical appliance. If a number of pins of the plug 11 of the adapter 1 is two, it will be the same as two pins of a general plug, and if a number of jacks of the socket 12 is two, it will be the same as two holes of a general socket.

[0023] In addition, the invention does not limit number and size of the pins of the plug 11 or the socket 12, for example, as shown in FIGS. 1 and 2, numbers of pins of the plug 11 and the socket 12 are six respectively. Of course, other changes in quantity or size are also included in the invention.

[0024] Furthermore, FIGS. 3 and 4 show an internal structure of the adapter 1 of the invention. The adapter 1 comprises a circuit board 14 in a middle internally (circuit in the circuit board 14 is omitted here), the circuit board 14 comprises an upper guide rod 15 disposing in a direction facing toward a power output end, and the circuit board 14 also comprises a lower guide rod 16 disposing in a direction facing toward a power input end; as shown in FIG. 5A, inside an inner edge of the upper guide rod 15 is a jack for inserting a pin of other electronic products, and the lower guide rod 16 is a pin of the adapter 1, which can be inserted into a jack of other electronic products.

[0025] FIGS. 6 and 7 are respectively perspective view and plan view of the upper guide rod 15 sleeved with an embossed heat dissipation layer inside the adapter 1 of the invention. Because the upper guide rod 15 facing toward a direction of the power output end often has a temperature higher than the lower guide rod 16 facing toward a direction of the power input end (due to large electric current), the upper guide rod 15 facing toward a direction of the power output end is sleeved with an embossed heat dissipation layer 151 as shown in FIG. 5B, the embossed heat dissipation layer 151 has a rough surface with creases to increase an air contact surface, with this principle the upper guide rod 15 enclosed therein is capable of effectively diffusing heat, providing excellent heat dissipation effect in an electrical connection environment of high voltage, high temperature and high electric current.

[0026] FIGS. 8 and 9 are respectively perspective view and plan view of the upper guide rod 15 and the lower guide rod 16 respectively sleeved with the embossed heat dissipation layer inside the adapter 1 of the invention. The lower guide rod 16 facing toward a direction of the power input end is also sleeved with an embossed heat dissipation layer 161, as shown in FIG. 5C, the embossed heat dissipation layers 151, 161 are capable of achieving better heat dissipation effect.

[0027] Particularly, when the adapter 1 of the invention is used on a load device that generates heat, the load device is capable of transferring heat outwardly from inside of the device through pins of the device to the adapter 1. The embossed heat dissipation layers 151, 161 inside the adapter 1 are capable of achieving excellent heat dissipation effect. FIG. 10 is a perspective view to exemplify the adapter 1 being connected to a load 13 that generates heat.

[0028] While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
