Publication number: 20240291200Abstract: A lever-type connector of the present disclosure is provided with a housing, a lever and a detecting member. A transportation position is set between a temporary locking position and a complete locking position in a movement path of the lever. The lever includes a lever lock portion and a transportation lock portion. The housing includes a complete locking portion for holding the lever at the complete locking position by being locked to the lever lock portion and a temporary locking portion for holding the lever at the transportation position by being locked to the transportation lock portion. The detecting member is held at the standby position by being locked by the lever lock portion at the transportation position, and allowed to move from the standby position to the detection position by releasing locking with the lever lock portion by the complete locking portion at the complete locking position.Type: ApplicationFiled: February 16, 2024Publication date: August 29, 2024Inventor: Masanori HIROTA
