Abstract

PROBLEM TO BE SOLVED: To surely hold the connecting state between a plug and a plug socket by the locking of a lock claw to a locking groove by providing the lock claw on at least either one of the plug and the plug socket, and providing the locking groove to which the lock claw is attachably and detachably locked on the other. SOLUTION: A plug socket 4 is formed in such a manner that its tip part can be fitted to a fitting recessed part provided on the tip part of a plug, and has a pin terminal insert hole 12 for inserting a pin terminal on the end surface. A contact part formed of a contact spring is provided opposite to the pin terminal hole 12 in the inner part of the plug socket 4. When the terminal pin protruded from the plug is inserted to the pin terminal insert hole 12, the terminal pin makes pressure contact with the contact part formed of the contact spring to electrically connect it. Thus, the connecting state between the plug and the plug socket can be held, and even in a cord having a large wire diameter, the connecting state can be held.
