Patent ID: 7048597

Claim:
A female terminal for heavy current, with reference to a depth direction, a width direction and a height direction being perpendicular to each other, into which and from which a blade of a blade-type male terminal having a substantially plate-shaped blade having a width greater than a height thereof and extending frontward in the depth direction is inserted and withdrawn, said female terminal comprising a body part being of a tubular form extending in the depth direction and being provided therein with a receiving space for receiving the blade from a rear side in the depth direction, said female terminal further comprising a connecting part being provided at a front in the depth direction of the body part and being adapted to be connected with a conductor, said body part having a first elastic piece being provided at least on one side in the height direction of the receiving space such that the first elastic piece can undergo elastic deformation in the height direction and being provided, on an inner face thereof, with a first contacting part extending for a certain width, said body part further having a second elastic piece being provided at least on one side in the width direction of the receiving space such that the second elastic piece can undergo elastic deformation in the width direction and being provided, on an inner face thereof, with a second contacting part extending for a certain height, said female terminal for heavy current being so structured that upon insertion of the blade into the receiving space the first contacting part of the first elastic piece will contact, with a contact pressure, a first end face in the height direction of the blade and the second contacting part of the second elastic piece will contact, with a contact pressure, a second end face in the width direction of the blade, said first and second elastic pieces being so configured and arranged such that both said first contacting part will contact said first end face and said second contacting part will contact said second end face on a single common contact plane extending normal to the depth direction, and said body part including a tubular front end part at a front end of said body part and a tubular rear end part at a rear end of said body part, and said front end part and said rear end part being connected to each other by said first elastic piece and by said second elastic piece respectively extending continuously and integrally therebetween.
