Press-fit joint, gas sensor comprising same, and method for manufacturing same

A crimp contact, a gas sensor including the crimp contact for outputting a signal from a sensing portion of a sensor element to an external device, and a method for manufacturing the crimp contact. The crimp contact includes a barrel portion crimped so as to fix a plurality of lead core wires of an electrical lead connected to the external device. A hold portion constituting the barrel portion is formed such that the lead core wires of the electrical lead are disposed in an U-shaped hold portion so as to be crimped between an anvil and a crimper. An outer surface of the U-shaped hold portion has a plating layer thereon to thereby constantly secure slidability between a sliding face of the crimper and the outer surface of the U-shaped hold portion. The crimp contact is able to secure slidability between an outer surface of a hold portion and a sliding face of a crimper without applying any lubricant to the sliding face of the crimper, and can be used under a high temperature environment.
