Claim Text:
1. A wire-to-board connector comprising: a plug connector including a plug contact to which a wire is attached, and a plug housing that holds the plug contact; and a receptacle connector that is mounted on a connector mounting surface of a board and includes a receptacle contact corresponding to the plug contact, and a receptacle housing that holds the receptacle contact, the plug connector being mated with the receptacle connector to thereby allow the plug contact to contact the receptacle contact, wherein in a mated state in which the plug connector is mated with the receptacle connector, a vicinity portion of the wire, the vicinity portion being located in the vicinity of the plug connector, extends along the connector mounting surface of the board, a mating direction in which the plug connector is mated with the receptacle connector is a direction approaching the connector mounting surface of the board, the plug housing includes a plug side surface as a side surface of the plug housing, the receptacle connector includes a side surface opposing portion that is opposed to the plug side surface in the mated state, the plug side surface is provided with a claw portion projecting toward the side surface opposing portion, the claw portion includes a plug lock surface that faces in a direction away from the connector mounting surface of the board and extends in a wire direction specified as a longitudinal direction of the vicinity portion in the mated state, the side surface opposing portion of the receptacle connector includes a receptacle lock surface that faces in a direction approaching the connector mounting surface of the board and is opposed to the plug lock surface in the mated state, the plug lock surface includes a lock maintaining surface disposed on a side in a connector wire direction in which the wire is viewed from the plug connector in the wire direction, and an unlocking surface disposed on a side in a wire connector direction which is opposite to the connector wire direction, and in a cross-section orthogonal to the wire direction, wherein that an angle formed between the lock maintaining surface and a reference plane that is a portion of the plug side surface located on a side farther from the connector mounting surface of the board than the claw portion is a lock maintaining angle θ
