Description

This invention relates to a lever-type connector having a connector position guarantee mechanism. To ensure the proper mating state of the connector, a Connector Position Assurance (CPA) mechanism is used. For example, the connector described in Patent Document 1 allows for detection of the proper mating state by inserting a mating detection member (CPA member) into a housing formed in the first housing after the first housing has been mated by rotating and sliding a lever. The mating detection member is movably supported by a lever provided in the second housing, and is pushed into the housing of the first housing after the lever operation is completed.

[Overall schematic structure] As shown in Figures 1 to 3, the lever-type connector 1 (hereinafter referred to as connector 1) comprises, as its main components, a plug housing 10 that holds a plurality of female contacts (not shown), a lever 20 provided on the plug housing 10, and a CPA member 30 provided on the lever 20. The plug housing 10, lever 20, and CPA member 30 are all formed from resin material by injection molding. The lever 20 is configured to allow lever operation to engage the plug housing 10 with the mating housing 80 of the mating connector 8 by rotational displacement from the first position P1 shown in Figure 1(a) to the second position P2 shown in Figure 1(b). When the plug housing 10 and the mating housing 80 are mated, the female contact of the connector 1 and the male mating contact (not shown) of the mating connector 8 are electrically connected. Note that, as a component of the mating connector 8, only the mating housing 80 is shown, and other components, such as the mating contacts held in the mating housing 80, are not shown. The CPA member 30 is configured to detect the correct mating state between connector 1 and mating connector 8. As described later, the plug housing 10 and mating housing 80 are mated by completing a lever operation in which the lever 20 is rotated to the second position P2 while pressing the CPA member 30, which is locked by the lever 20. The locking of the CPA member 30 by the lever 20 is released simultaneously with the completion of the lever operation when the CPA member 30 is pushed by a part of the plug housing 10. Therefore, immediately after the completion of the lever operation, the CPA member 30 is pushed in and activated by the load continuously applied to the CPA member 30 from before the lever operation was completed. Figures 1 to 5 show the state in which the CPA member 30 is not pressed in. The detailed configurations of the plug housing 10,
