Crimping apparatus
View Patent ↗A crimping apparatus includes an anvil for supporting a metal terminal including a base plate portion for mounting an electric wire thereon and a pair of crimping piece portions extending upwardly respectively from opposite side edges of the base plate portion, and a crimper which has a press-fastening portion for press-fastening the crimping piece portions. The anvil and the press-fastening portion of the crimper cooperate to press-fasten the crimping piece portions for crimping the crimping piece portions to the electric wire mounted on the metal terminal. The press-fastening portion is subjected to a mirror finish.
1. A crimping apparatus, comprising:
an anvil for supporting a metal terminal including a base plate portion for mounting an electric wire thereon and a pair of crimping piece portions extending upwardly respectively from opposite side edges of the base plate portion; and
a crimper which has a press-fastening portion for press-fastening the crimping piece portions,
wherein the anvil and the press-fastening portion of the crimper cooperate to press-fasten the crimping piece portions for crimping the crimping piece portions to the electric wire mounted on the metal terminal, and
wherein the surface of the press-fastening portion has a mirror finish and a hard chrome plating layer provided thereon.
2. The crimping apparatus according to claim 1 , wherein the mirror finish has surface roughness Ra of not more than 0.1 μm.
3. The crimping apparatus according to claim 1 , wherein the hard chrome plating has a hardness of Hv 850 to 1000, and a thickness of 3 to 5 μm.
