Electrical system with device for preventing electrostatic discharge

摘要

An electrical system includes a first connector ( 1 ), a second connector ( 2 ), and a printed circuit board (PCB) on which the second connector is mounted. The first connector has a mating portion ( 112 ) with numbers of contacts ( 13 ) therein and an elastic post member ( 14 ) standing higher than the mating portion. The second connector defines a mating connector fitting section ( 212 ) with numbers of contacts ( 23 ) therein and a through hole ( 217 ) for guiding and receiving the post member. The post member functions as first conductor that contacts a second conductor ( 31 ) located on the PCB exposed in the through hole.
