Abstract
A dummy tab is detachably held in a female connector housing. A dummy spring is detachably held in a male connector housing. When a male and female connection terminals are connected, the dummy tab comes into contact with the dummy spring before a contact protrusion comes into contact with a contact spring. This arrangement generates an arc discharge in the contact between the dummy tab and the dummy spring before the contact protrusion comes into contact with the contact spring, thereby to protect the female and male connection terminals as original contacts from deterioration or damage under an arc discharge.
