Connection apparatuses are provided, in which at least one isolation transformer comprises a primary coil and a secondary coil each comprising a first end, a second end and a tap, and a high voltage impulse protector is disposed between the primary coil of the isolation transformer and a ground terminal, discharging an overcurrent caused by a high voltage impulse to the ground terminal by point discharge when a high voltage impulse event occurs.

Connection apparatus with high voltage impulse protection

A surge protection circuit and a connector and an electronic apparatus using the circuit are provided. The connector includes a plurality of metal lines, a plurality of resistors, a ground metal, and a capacitor. Each metal line has a pointed end. There is a distance between the pointed end of the metal lines and a pointed end of the first end of each resistor corresponding to the metal line. The capacitor is coupled between the ground metal and second end of the resistors. Thus the surge endurance of product can be increased by the invention, and the damage to the internal components of product can be prevented.

Circuit for preventing surge, connector and electronic apparatus thereof

The present invention provides an electro-magnetic interference protection circuit for a clock buffer. The present invention not only uses a ferrite bead that is serially connected with the power source of the clock buffer to protect the clock buffer from electro-magnetic interference. The ferrite bead also connects in parallel with a capacitor to reduce the distortion of a clock signal out-putting by the clock buffer due to the ferrite bead, thereby making the communication devices work properly.

Electro-magnetic interference protection circuit and method for a clock buffer

A connecting cable for bridging a computer host and a peripheral device including a signal line for data transmission and a power cable. A portion of the power cable is wrapped around the signal line to form the coil wire. Therefore, rapid noise variation of a braided wire on the signal line can pass the coil wire to induce a rapid change of magnetic flux and then further to generate a reverse induced current for eliminating the noise intensity on the power cable.
