20130037701 | STANDBY CIRCUIT - The present invention discloses a standby circuit. The standby circuit is coupled to an electric device for providing a standby voltage to the electric device when the electric device is not turned on. The standby circuit includes a light emitting module and an energy converter. The light emitting module receives an AC current and is driven by the AC current to generate light. The energy converter receives the light generated by the light emitting module and converts the light into the standby voltage. Therefore, the present invention can simplify the design of traditional standby circuit in a television. | 02-14-2013 |
20130076471 | TRANSFORMER AND ASSEMBLING METHOD THEREOF - A transformer includes a winding frame, a primary coil, an insulating cover, a secondary coil, and a core assembly. The winding frame has a winding portion formed with a first side portion and a second side portion oppositely. A plurality of first pins and second pins are disposed on the first and second side portions, respectively. The primary coil is wrapped around the winding portion of the winding frame and connected to the first pins. The insulating cover is fitted over the primary coil. The secondary coil is wrapped around the insulating cover and connected to the second pins. The core assembly is arranged on the winding frame. A transformer assembling method is also disclosed. The coil wrapping process for the transformer can be expedited and associated cost can be reduced. | 03-28-2013 |
20130076473 | TRANSFORMER - A transformer includes a bobbin, a primary coil, a secondary coil, and a core assembly. The bobbin has a winding portion. At least one first winding groove and at least one second winding groove are formed on the winding portion. The first winding groove and the second winding groove are separated by a barrier. A notch is formed on the fringe portion of the barrier. The primary coil is wrapped in the first winding groove, and the secondary coil is wrapped in the second winding groove. The notched barrier increases the creepage distance between the primary coil and the secondary coil in meeting the safety standards. | 03-28-2013 |

20140133207 | CURRENT CONVERTOR - The current convertor comprises a current converting device and a combinative plug. The current converting device comprises a casing and a current converting module arranged in the casing. The casing has at least one track extended from an outer surface of the casing along a sliding direction. The combinative plug comprises an insulating body and a conductive pin set disposed on the insulating body. The insulating body has a quick releasing portion conformed in shape to the track. The quick releasing portion is detachably sliding on the track of the casing along the sliding direction for maintaining the relative position between the current converting device and the combinative plug and for establishing electrical connection between the conductive pin set and the current converting module. | 05-15-2014 |
20140134857 | CURRENT CONVERTOR - The current convertor comprises a current converting device and a sliding cover. The current converting device comprises a casing, a current converting module arranged inside the casing, two conductive terminals electrically connected to the current converting module, and a first sliding module disposed on the casing. The conductive terminals are partially exposed from the casing. The sliding cover has a second sliding module having two thru holes. The second sliding module is slidably disposed on the first sliding module for enabling the sliding cover to slide between a first position and a second position relative to the casing. When at the first position, the conductive terminals pass through the thru holes of the sliding cover for inserting into the conventional outlet, and when at the second position, the conductive terminals are arranged in a space surrounded by the sliding cover and the casing. | 05-15-2014 |
20140140010 | CURRENT CONVERTING DEVICE - A current converting device comprises a casing, a current converting module arranged in the casing, a buffer structure, and a heat dissipative structure abutting on at least half of an outer surface of the casing. The current converting module has a circuit board. The buffer structure has a first and a second buffer portions disposed on the inner surface of the casing and facing to each other. The circuit board has a thru hole, the second buffer portion passes through the thru hole and inserts into the first buffer portion, the first buffer and the second buffer portions surroundingly define a buffer space and a gap in communication with the buffer space. When the casing is pressed, the air in the buffer space flows out via the gap for reducing the relative speed between the first and the second buffer portions. | 05-22-2014 |
