ABSTRACT:
Terminal insertion methods for preventing a terminal and a connector housing from being broken in the event that a secondary insertion fails. The distance from a rear end of a terminal to secondary insertion claws, which are behind primary insertion claws, is set approximately to the required insertion stroke. When the terminal interferes with the connector housing during the secondary insertion process, a wire between the rear end of the terminal and the rear insertion claws is made to buckle to release an overload acting on the terminal and connector housing. A primary chuck cylinder for the front insertion claws is connected to a rod of a primary insertion cylinder; the primary chuck cylinder is secured to a guide plate; a secondary insertion cylinder 10 is secured to the guide plate; and a secondary chuck cylinder for the rear insertion claws is connected to a rod of the secondary insertion cylinder. In the terminal insertion apparatus of the above construction, the pressure of the primary insertion cylinder is set smaller than that of the secondary insertion cylinder so as to release the overload, which is produced when the terminal interferes with the connector housing during the secondary insertion process, to the primary insertion cylinder.
