POWER SUPPLY JACK, JACK COVER USED FOR THIS POWER SUPPLY JACK, AND ELECTRONIC DEVICE USING THE SAME

摘要

A power supply jack that is used to effect reductions in size and thickness. A pipe 2 has a stop ring groove 2a in the outer periphery. A power supply minus spring 3 is fixed at a portion thereof to the pipe 2 in the interior of the latter and has elasticity so as to contact the outer periphery of a power supply plug 11. A pin 5 for contact with the inner periphery of the power supply plug 11 is fixed to the pipe 2 by an insulation pipe 6. At this time, the insulation pipe 6 ensures insulation between the power supply minus spring 3 and the pin 5.
