Abstract:
1. A plug-in connector for DC wiring comprising: an insertion plug having blades, a plug receiver comprising insertion holes and a connection member, said insertion holes being configured such that said blades are inserted into the insertion holes, said connection member being electrically connected to said blades which are inserted through said insertion holes, said connection member comprising inversion springs, said inversion spring having electrical conductivity and having one end which is fixed, said inversion spring has an inversion portion which is invertible to move between a contact position and a non-contact position past a line segment which connects both ends of said inversion spring, when said inversion portion is in the contact position, said inversion portion is projected toward said blade which is inserted from said insertion hole such that said inversion portion is elastically contacted to said blade, when said inversion portion is in the non-contact position, said inversion portion is spaced from said blade by a predetermined distance or more, the predetermined distance is defined by a distance for cutting a flow of arc, at least one of an on-operation for moving said inversion portion of said inversion spring toward the contact position and an off-operation for moving said inversion portion of said inversion spring toward the non-contact position is performed by pushing said inversion portion with a part of said insertion plug according to operation of moving a body of said insertion plug when said insertion plug is attached and detached.
