Electrical connection system

摘要

An electrical connection system includes (1) a jack holding a pair of pins, (2) a plug holding a pair of electrical terminals respectively engaging with the above pins, (3) a shorting clip provided in the above jack for electrically shorting out the pins each other, (4) a latch unit provided in the above plug and (5) a cover provided in the above jack so as to be freely rotatable. The latch unit is movable between a first position where the shorting clip shorts out the pins and a second position where the shorting clip is moved to a non-shorting position. Rotation of the cover allows the plug to engage with the jack and the above latch unit to move to the above second position.
