Terminal connector, electric wire with terminal connector, and method of connecting terminal connector and electric wire
An object is to obtain a stable electric connection resistance under a mild crimping condition. The present invention is a terminal connector 12 that includes a crimp portion 30 to be crimped to an electric wire. The crimp portion 30 includes a base material, an aluminum layer or an aluminum alloy layer a surface on the base material, and a hard layer on a surface of the aluminum layer or the aluminum alloy layer. The hard layer is harder than the base material. The present invention may be an electric wire with a terminal connector 10 that includes the above terminal connector 12 and a covered electric wire 40 that includes a core wire 42 made of aluminum or aluminum alloy. The crimp portion 30 of the terminal connector 12 is crimped to the core wire 42.
