Title: Plug-in connector for DC wiring

Abstract: An objective is to produce the plug-in-connector for DC-wiring with safety by preventing degradation of contact points by shortening of period when arc is caused due to detaching and attaching the plug. An electrical outlet comprises an inversion-spring electrically connected to the plug's blade inserted from the insertion-hole. Both the ends of the inversion-spring are fixed to the inversion-spring's body, whereby the inversion-spring's intermediate-portion is moved between the contact position of making an elastically contact with the blade and the non-contact position of making a space having a predetermined distance or more for cutting the arc. The blade pushes the intermediate-portion to move it to the non-contact position by twisting the plug having a contact condition between the intermediate-portion and the blade. The intermediate-portion is inverted to have an elastic contact to the blade by pushing the push button to move the intermediate-portion, with non-contact position, by the driving member.
