Abstract: A connector comprises a housing and a connector position assurance (CPA) member. The housing is provided with a repositioning portion, a lock portion and a stopper. The CPA member has a base end portion, a regulating portion, a first arm portion, a distal end portion and a second arm portion. The distal end portion is provided with an abutment portion. The abutment portion is selectively positionable at a facing position or at a non-facing position. At least one of the first arm portion and the distal end portion is provided with a release projection. The release projection projects in a perpendicular direction from the at least one of the first arm portion and the distal end portion. Upon connection of the connector with a mating connector, the release projection is pushed by a mating release portion and moves the abutment portion from the facing position to the non-facing position.

Abstract: A board waterproofing connector includes a circuit board having a flexible plane conductor, a fitting cover having a fitting portion, and a seal member that demonstrates a sealing property and that is sandwiched between the circuit board and the fitting cover. The fitting cover has a lock portion attached to the circuit board, and the circuit board has a locked portion onto which the lock portion is locked. In a state wherein the seal member is sandwiched between the circuit board and the fitting cover, the lock portion of the fitting cover is locked onto the locked portion of the circuit board such that the seal member waterproofs a space between the circuit board and the fitting cover.
