1. A CPA attachment structure comprising:
a CPA-side lock structure provided at a CPA member, the CPA member being configured to be temporarily locked to a connector housing and to be finally locked to the connector housing at a time of fitting to a mating connector housing to ensure fitting, the CPA-side lock structure being configured to bring the CPA member temporarily locked to the connector housing and finally locked to the connector housing at the time of the fitting; and
a connector-side lock structure provided at the connector housing and configured to bring the CPA member temporarily locked and finally locked at the time of the fitting,
wherein the CPA-side lock structure includes:
a pair of arms each extending in a direction corresponding to a fitting direction and aligned in an in-plane direction of a housing outer surface at a time when the CPA member is temporarily locked to the connector housing, the pair of arms being bendable in the in-plane direction; and
CPA-side lock portions provided at the pair of arms, respectively, the CPA-side lock portions being configured to be temporarily locked to the connector-side lock structure, the CPA-side lock portions being configured to be released from the temporary locking by the pair of arms being bent in the in-plane direction by the mating connector housing at the time of the fitting, and the CPA-side lock portions being configured to be finally locked to the connector-side lock structure by the CPA member being pushed in the fitting direction, and
wherein the connector-side lock structure includes:
a pair of ribs standing on the housing outer surface at an interval corresponding to an arrangement interval of the pair of arms, the pair of ribs each extending in the fitting direction;
temporary lock portions which are provided at the pair of ribs, respectively, and to which the CPA-side lock portions are temporarily locked; and
final lock portions which are provided at the pair of ribs, respectively, on a front side in the fitting direction with respect to the temporary lock portions, and to which the CPA-side lock portions are finally locked.
