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.

Abstract: A plug cap freely mountable on or removable from an elongated bore, especially for a spark plug in internal combustion engines or the like. The plug cap is provided with a rain cover, seal, and a pipe-holding portion. The latter has, on its internal face, a circular groove and a plurality of protrusions projecting radially inwardly. These grooves and protrusions, and the deflection thereof on insertion into the bore, give elasticity to the seal and to the pipe-holding portion. When the plug cap is pressed into the bore, there is no curling up of the pipe-holding portion, thereby ensuring a reliable seal. After insertion, the protrusions of the pipe-holding portion, which are formed integrally with the seal, are pressed against the external face of the ignition pipe, so that the latter can be held more reliably.
