Abstract:
A connector is provided. The connector includes a connector body, a signal transmitting unit, a cover, a fastening plate, and an extension plate. The connector body has side walls to enclose an assembly hole. The signal transmitting unit is disposed in the assembly hole. The cover has a first end, a second end, and a first pivot and is disposed outside the assembly hole. The first end and the first pivot are disposed on two ends of a side case of the cover. The second end is opposite to the first end while the first pivot is axially connected to one side of the assembly hole. The fastening plate has a second pivot opposite and parallel to the first pivot. The second pivot axially connected to the side wall around the assembly hole. One end of the extension plate has a third pivot parallel to the first pivot and is rotatably connected to the fastening plate. The other end of the extension plate has a pressing portion to press the second end of the cover from outside to make the cover rotates toward the connector body and press the signal transmitting unit.
Abstract:
A security socket for use with a panel having at least one assembly hole is provided. The security socket includes a socket and a security unit. The socket has a slot and is inwardly connected to the assembly hole of the panel. The security unit is outwardly assembled with the assembly hole of the panel to be engaged with the socket. The security unit has a protrusion and a through hole corresponding to the slot of the socket, and the protrusion perpendicularly extends from one side of the through hole, wherein the protrusion further has an insertion hole.
Abstract:
A wheel rim device with patterned light capable of automatically generating electric power has a wheel rim, an automatic generating assembly, a rectifier/filter circuit, a circuit board, a programmable chip and several light emitting components. The automatic generating assembly is accommodated on an end face of a wheel axle of the wheel rim. The circuit board is disposed on a wheel spoke of the wheel rim. The rectifier/filter circuit, the programmable chip and the light emitting components are disposed on the circuit board. Input terminals of the rectifier/filter circuit are connected to lead out wires of the automatic generating assembly. The programmable chip has a power source terminal, a trigger terminal and several I/O terminals. The power source terminal is connected with the output terminal of the rectifier/filter circuit. Each of the I/O terminals is connected with one of the light emitting components.
Abstract:
A method and an apparatus measure an actual responsive time for a relay and control the open/close timing for the relay. The apparatus comprises a microprocessor and two conversion units. One conversion unit processes an input sinusoidal signal for the microprocessor and the microprocessor sends a control signal to energize or de-energize a coil of the relay at an arbitrary time point. Another conversion unit senses a waveform change after the switch of the relay and sends a state signal to the microprocessor. Therefore, the microprocessor can obtain an actual responsive time of the relay by the difference between the control signal and the state signal. The microprocessor will apply next control signal with a time lead of the responsive time before next zero-crossing point to achieve zero-crossing switch for the relay.
