|20120270414||Freely Rotatable Electrical Conduction Structure And Receptacle Using The Same - The present invention provides a freely rotatable electrical conduction structure including at least two cylindrical electrical conduction portions, an insulated material portion and at least two electrical conduction terminals. The at least two cylindrical electrical conduction portions are arranged separately along an axis, wherein the inner surface of each cylindrical electrical conduction portion is welded with an end of a conducting wire. The insulated material portion is combined with the at least two cylindrical electrical conduction portions via injection molding to form a circular shaft assembly. The at least two electrical conduction terminals correspond to the at least two cylindrical electrical conduction portions respectively, and each electrical conduction terminal partially projects to form an arc contact portion configured to abut onto the outer peripheral surface of its corresponding cylindrical electrical conduction portion. Each electrical conduction terminal is allowed to rotate around its corresponding cylindrical electrical conduction portion with its arc contact portion keeping contacting and conducting with the outer peripheral surface.||10-25-2012|
|20120156915||POWER ADAPTER ASSEMBLY - The invention provides a power adapter assembly including an adapter body, a replaceable plug and a rotation locking collar. The adapter body comprises a cylindrical casing and a circular plug receiving base fixed on top of the cylindrical casing. The plug receiving base has a recess on the top thereof and a circular peripheral surface, wherein the recess has an engagement block on the side wall thereof. The circular peripheral surface has a flange with an indentation on the top edge thereof, and a guiding groove formed from the indentation and extending downward to the bottom edge thereof. The replaceable plug is detachably mounted onto the plug receiving base and comprises a cylindrical support base comprising an upper portion and a lower portion sized to fit into the recess of the plug receiving base. The upper portion has an elongated engagement groove along its peripheral surface with one end extending to the bottom edge thereof and alignable with the guiding groove. The lower portion has an engagement groove adapted to engage with the engagement block. The rotation locking collar is detachably sleeved onto the plug receiving base and the support base, wherein the locking collar has a tab member on the inner top edge thereof adapted to enter the guiding groove and said one end of the elongated engagement groove. The tab member is further allowed to rotate into and engage with the elongated engagement groove by rotation of the locking collar.||06-21-2012|
|20120139674||MICRO SWITCH - A micro switch is disclosed and includes a bracket, at least one conductive terminal assembly, a push rod and an electro-magnet. The conductive terminal assembly has a first terminal, an elastically conductive plate, a spring and a second terminal. A first end of the spring is hooked on the first terminal, and a second end thereof is hooked on the elastically conductive plate. The push rod is slidably installed on the bracket, and has a recess, a sliding inclined surface and a top flat surface. The push rod can be slid to cause the spring to slide into the recess and onto the top flat surface. Thus, the spring can actuate the elastically conductive plate to pivotally rotate and abut against the second terminal. Thus, the structure of the micro switch is simplified and the installation thereof is easier.||06-07-2012|
|20100304620||A POWER PLUG WITH A ROTARY BODY INCLUDING A PIVOTING PORTION - A power plug connector for connecting with a wire includes a shell with a receiving cavity being opened through a rear end thereof, a pin assembly fastened in a front of the shell and stretching forward beyond the shell, and a rotating body including a pivoting portion rotatably pivoted in the receiving cavity of the shell. The rotating body defines a perforation penetrating through the pivoting portion. One end of the wire is passed through the perforation of the rotating body and then electrically connected with the pin assembly. The rotating body can rotate in the receiving cavity of the shell so that can avoid the wire twisting and fracturing in use and is further easy to arrange the wire in order. Therefore, it prolongs the use life of the power plug connector.||12-02-2010|
|20100270985||DC-DC CONVERTER - A DC-DC converter includes a voltage input module receiving an input voltage from an exterior power supply, a voltage transforming module connected with the voltage input module for transforming the input voltage into a proper output voltage, a voltage output module connected with the voltage transforming module for supplying the proper output voltage to an exterior electric appliance, a first detecting module connected with the voltage output module for detecting an output current of the voltage output module and sending a corresponding current signal, a second detecting module connected with the voltage output module for detecting the output voltage of the voltage output module and sending a corresponding voltage signal, and a control module for receiving and analyzing the corresponding current and voltage signals and then generating a corresponding control signal so as to control the output voltage of the voltage transforming module for protecting the electric appliance.||10-28-2010|
|20100136812||Safety Socket - A safety socket adapted for receiving a terminal of a plug includes a socket housing with a plurality of electrodes being mounted thereon, a socket cover coupled with the socket housing and an insulating case mounted between the socket housing and the socket cover. The socket cover has a plurality of insertion holes corresponding to the electrodes. And the insulating case is located above the electrode for holding the terminal separated from the electrode and has a through hole aligned with the electrode and the insertion hole.||06-03-2010|
|20090017669||SOCKET CONNECTOR WITH LOOSENING-PROOF STRUCTURE - A socket connector with loosening-proof structure includes an insulating housing which defines insert holes in a front surface thereof and at least a receiving hole at one side thereof. The insulating housing has an upper cover and a lower cover. Electric terminals are received in the insulating housing respectively. Every electric terminal has a fix arm, an elastic arm locating at one side of the fix arm and a connecting portion extending from the rears of the fix arm and the elastic arm for connecting with a cable member. The elastic arm defines a guide portion at the front. The inner side of the guide portion defines a hook which tilts rearward to form a bevel plane. A button is configured in the receiving hole of the insulating housing. The button protrudes inward to form a shaft which is against the elastic arm.||01-15-2009|
