ABSTRACT:
A connector for a printed circuit board having a housing defining a hollow. There is a plurality of slits in the back wall and a terminal is inserted in each one. The terminal includes a pressing piece which is capable of flexing under the influence of the introduction of a retainer so that it is spaced apart from the circuit board. The gap therebetween is greater than the thickness of the board. The housing is also provided with weakened areas, including slits in the sides of the housing and a line of reduced thickness on an upper wall of the housing, which facilitate movement of the upper wall and the pressing piece into the flexed position. The gap therebetween is greater than the thickness of the board. After the retainer and circuit board have been fully inserted, the pressing piece returns to its rest position, in which the gap is equal to or less than the thickness of the circuit board. This provides a good electrical contact between the pressing piece and the board. The retainer, which may be integral with the board, has a cavity which receives a portion of the circuit board. Attached thereto is a connecting member which enters the hollow and presses the terminal into a flexed position separated from the board. In this way, the terminal is out of contact with the circuit board until the board has been fully inserted. This not only prevents damage to the board by abrasion, but also allows entry of a very flexible board without any danger of crumpling, even if the assembly is carried out with one hand.
