Abstract

The terminal crimping quality decision device determines the quality of a terminal crimped on a core of an electrical cable by a terminal crimping apparatus. The device uses a characteristic value envelop obtained when the terminal is crimped on the core. A reference value envelop is obtained from a characteristic value envelop obtained when a terminal is correctly crimped on the core. An increment envelop of the reference value envelop is calculated to obtain at least one singular point of the reference value envelop. The quality of a terminal crimped by the terminal crimping apparatus based on a characteristic value envelop of the crimped terminal. The characteristic value envelop is obtained in an envelop division separated by the singular point.
