Abstract: A power connector system having a right-angle type plug connector or a straight type plug connector engageable with a header connector. The right-angle type plug connector is a plug connector having a mating direction, which is 90 degrees from the centerline of the cables exiting from the plug connector. The straight type plug connector is a plug connector having a mating direction, which is parallel to the centerline of the cables exiting the back of the plug connector. The header connector holds at least a female receiving terminal or receptacle made of a high electrical conductivity material. The female receiving terminal or receptacle includes fingers that extend parallel to each other, and are spaced apart from each other, and further includes a reinforcing spring member. The plug connector holds at least a male rectangular tab terminal, the male rectangular tab terminal having a short edge and a long edge.

Abstract: An electric connector 1 has an integrally-molded connector housing 2 and contact terminals 3 installed therein. The connector housing 2 has a supporting base 2A with front and rear surfaces, a pair of arm parts 2C, 2C extending outward, with a particular spacing therebetween, from the rear surface of the supporting base 2A, and a terminal attachment part 2B to which the contact terminals 3 are installed and which extends outward from the front surface of the supporting base 2A. The contact terminals 3 are installed to the terminal attachment part 2B. At each tip of the pair of arm parts 2C, 2C there is provided a latching parts 2D1, 2D1 with release finger which is detachably attached to a printed circuit board 5. An electric connector having an attaching means enabling simple installation to and removal from a circuit board is provided.
