1. A terminal fitting connection structure which presses contact spring pieces provided in a first terminal fitting to contact surfaces provided in a second terminal fitting so as to contact thereto, so that the first terminal fitting and the second terminal fitting are electrically connected to each other, wherein
the first terminal fitting includes:
a first terminal body which extends on a center axis of the first terminal fitting and has a base end to which an electric wire is connected substantially coaxially with the center axis of the first terminal fitting,a first annular portion which is formed at a tip end of the first terminal body in an annular shape concentrically with the center axis of the first terminal fitting, anda plurality of the contact spring pieces which are provided at a plurality of points arranged on an outer periphery of the first annular portion at predetermined intervals in a peripheral direction of the first annular portion, the contact spring piece includes:
a spring support portion which extends outward in a radial direction of the first annular portion from the outer periphery of the first annular portion,an elastic piece which extends from the spring support portion along the outer periphery of the first annular portion and has a tip end side that is displaceable in a direction of the center axis of the first terminal fitting, anda contact protrusion which protrudes from the elastic piece so as to protrude further toward a mated terminal side than a tip end of the first annular portion, and the second terminal fitting includes:
a second terminal body which extends on a center axis of the second terminal fitting and has a base end to which an electric wire is connected substantially coaxially with the center axis of the second terminal fitting,a second annular portion which is provided at a tip end of the second terminal body in the same annular shape as that of the first annular portion of the first terminal fitting concentrically with the center axis of the second terminal fitting,a plurality of the contact surfaces which protrude outward in a radial direction of the second annular portion from an outer periphery of the second annular portion at the same intervals as those of the plurality of the contact protrusions in the first terminal fitting, anda plurality of contact release portions which are positioned between the adjacent contact surfaces and allow the contact protrusions to be inserted into the contact release portions. |
