Abstract: An apparatus for power source protection with automatic latch-off is provided for use in an electronic apparatus. The electronic apparatus includes a power supply and a main functional circuit, such as a notebook computer. The power supply is coupled to the main functional circuit via an electronic switching device, so as to power the main functional circuit via a power source terminal of the electronic switching device. The apparatus for power source protection with automatic latch-off includes a low-voltage-triggered latch-off device and a low-voltage-triggered responding device. The low-voltage-triggered latch-off device is coupled to the electronic switching device, so as to control the on or off state of the electronic switching device. The low-voltage-triggered responding device is coupled to the power source terminal and the low-voltage-triggered latch-off device.

Abstract: In a low insertion force connector, cam grooves are formed in a slider for imparting a motion, and guide pins are formed on a connector holder for receiving the motion, and the slider and the holder are connected together, with the guide pins engaged respectively in the cam grooves, and when the slider is moved, the guide pins are moved respectively along the guide grooves, thereby moving the holder, so that the connector is fitted into a mating connector. Radiused grooves 22 of an arcuate cross-section are formed in those surfaces from which the guide pins 21 project, each of the radiused grooves being continuous with a proximal end of the associated guide pin 21.
