Abstract: A connector for a printed circuit board which minimizes the deformation of the positioning member for aligning terminals. The engaging members are located at the outside of guide surfaces formed on the outer surfaces of the housing of the connector. The spacing between the engaging members is longer than if they were located inwardly of the guide walls projecting from the front surface of the housing. Accordingly, the deformation per unit length of the positioning member is small. Such a small deformation of the positioning member minimizes the misalignment of the holes into which the terminals are to enter. Thus, the terminals can be aligned with great accuracy.
