PROBLEM TO BE SOLVED: To make a barrel of an open-barrel crimp terminal unlikely to be buckled by caulking forces applied to a pair of caulking pieces when caulking and fixing a wire to the barrel by means of the caulking pieces.SOLUTION: When a core wire caulking piece 50 or a wire caulking piece 55 of a wire connection part 52 is curved and deformed inside at a certain degree, neighboring two protrusions 50a and 50a (55a and 55a) on an inner surface are abutted to each other to prevent the caulking piece from being curved and deformed inside anymore. Therefore, after the protrusions 50a and 50a (55a and 55a) are abutted to each other, a portion of the core wire caulking piece 50 or the wire caulking piece 55 closer to a distal end than the protrusion 50a (55a) is surely curved and deformed inside in a concentrated manner. Thus, the wire connection part 52 is prevented from being buckled and deformed or cracked by disabling the core wire caulking piece 50 or the wire caulking piece 55 from being curved and deformed, and a crimp defect of a crimp terminal 51 to a wire 61 or a conduction defect between both the wire 61 and the crimp terminal 51 can be prevented. 【課題】オープンバレル型の圧着端子のバレルに電線を一対の加締め片により加締め固定する際に、加締め片に加わる加締め力によるバレルの座屈が起こりにくくする。【解決手段】電線接続部５２の芯線加締め片５０や電線加締め片５５がある程度内側に湾曲変形されると内面の隣り合う２つの凸部５０ａ，５０ａ（５５ａ，５５ａ）同士が当接してそれ以上内側への湾曲変形を阻止する構成とした。このため、凸部５０ａ，５０ａ（５５ａ，５５ａ）同士が当接した以後は、芯線加締め片５０や電線加締め片５５の凸部５０ａ（５５ａ）よりも先端側の部分を集中的かつ確実に内側に湾曲変形されるようになる。このため、芯線加締め片５０や電線加締め片５５が湾曲変形できないことに起因する電線接続部５２の座屈変形や亀裂の発生を防ぎ、電線６１に対する圧着端子５１の圧着不良や両者間の導通不良を防ぐことができる。【選択図】図４
