<p><P>PROBLEM TO BE SOLVED: To extend a life of a crimper type blade. <P>SOLUTION: In a terminal crimping machine 30 of an electric wire connection terminal 1 crimping and fixing a conductive core material S of an electric wire E between wire standing pieces 4a and 4b, an anvil type blade 31 supporting the electric wire connection terminal 1, and a crimper type blade 32 pressing the electric wire connection terminal 1 to the anvil type blade 31 are arranged. A guide groove 34 for accessing the electric wire connection terminal 1 and the anvil type blade 31 comprises guide inner walls 35a and 35b guiding the electric wire connection terminal 1 and the anvil type blade 31 to a deep part of the groove, arch groove bottoms 36a and 36b caulking the wire standing pieces 4a and 4b, and chamfering parts 38a and 38b along a ridge line of the arch groove bottoms 36a and 36b, the groove inner walls 35a and 35b, and a blade surface 37 of the crimper type blade 32. Lateral width W1 of the chamfering parts 38a and 38b is larger than lateral width W2 of the arch groove bottoms 36a and 36b. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
