Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
216 words
An electric terminal, comprising: tab receptacle means including a bottom wall portion, two lateral wall portions, an upper wall portion formed by a tip portion of each of the lateral wall portions, and an opening portion defined by the wall portions and into which a male terminal is to be inserted; contact means provided on the bottom wall portion of the tab receptacle means and resiliently biased toward the upper wall portion of the tab receptacle means so as to support the male terminal in cooperation with the upper wall portion; and a concave portion for ensuring electrical connection between the male terminal and the upper wall portion, the concave portion being formed on the upper wall portion of the tab receptacle means along the entire width thereof, which is perpendicular to the insertion direction of the male terminal, by drawing the tip portion of each of the respective lateral wall portions with respect to the remaining part of the lateral wall portions in such a manner that each of the top portions is bent substantially perpendicularly to the remaining part of the respective lateral wall portions so as to form respective corners therebetween and to make a central portion of the top portions depressed, characterized by the absence of a slit at said respective corners.
