Abstract: An electrical connector such as a miniature power jack contains a single snap-fit post for connection to a printed circuit board. A plurality of alignment posts and electrical terminals also extend from the bottom of a housing. The snap fit post is located off-center in an asymmetrical arrangement and is located closer to an access opening which receives an external plug which is removably insertable over a cylindrical pin connected to one of the terminals. A spring forms a make and break electrical power jack. The snap fit post has an enlarged head with tapered end surfaces and canted shoulders located intermediate between the tapered surfaces and the housing to form a snug interference fit with the printed circuit board aperture. The electrical connectors can be located within specially designed pockets provided on a carrier tape for automatic insertion machinery.
