Arrangement for connecting an electrical connector to a printed circuit board

Claim 2

In an arrangement for connecting an electrical connector to a mating printed circuit board, the connector including a dielectric housing having top and bottom walls joined by spaced apart side walls, means defining an elongated slot between the top and bottom walls for receiving the mating printed circuit board, and a plurality of terminals mounted in the housing with contact portions along the slot for engaging contact pads on the circuit board, wherein the improvement comprises at least one pair of aligned apertures passing through the top and bottom walls of the housing, an aperture in the circuit board adapted for alignment with the apertures in the housing when the circuit board is inserted into the slot, and a fastener adapted to be received in the housing apertures and the aligned board aperture to maintain the board in mating relationship with the connector, the fastener being adapted to clamp against the top and bottom walls of the housing, and the width of the slot being greater than the thickness of the printed circuit board so that clamping forces of the fastener against the top and bottom walls of the housing are not transmitted to the printed circuit board, said housing apertures being located in a wing portion of the housing located outside one of said side walls and said printed circuit board including a tongue portion insertable into slot and an end wing portion having the board aperture therein, the end wing portion being located outside the one side wall and separated from the tongue portion by a notch.

Claim 3

In an arrangement for connecting an electrical connector to a mating printed circuit board, the connector including a dielectric housing having top and bottom walls joined by spaced apart side walls, means defining an elongated slot between the top and bottom walls for receiving the mating printed circuit board, and a plurality of terminals mounted in the housing with contact portions along the slot for engaging contact pads on the circuit board, wherein the improvement comprises two pairs of aligned apertures passing through the top and bottom walls of the housing near opposite ends of the slot, a pair of apertures in the circuit board adapted for alignment with the two pairs of apertures in the housing when the circuit board is inserted into the slot, and a pair of fasteners adapted to be respectively received in the pairs of housing apertures and the respective aligned board apertures to maintain the board in mating relationship with the connector, the fastener being adapted to clamp against the top and bottom walls of the housing, and the width of the slot being greater than the thickness of the printed circuit board so that clamping forces of the fastener against the top and bottom walls of the housing are not transmitted to the printed circuit board, each pair of apertures in the top and bottom walls of the housing being located adjacent and outside a respective one of said side walls in the wing portions whereby the side walls provide reinforcement against the clamping forces of the fasteners, and the printed circuit board including a tongue portion insertable into said slot and a pair of end wing portions having apertures therein, the end wing portions being located outside the side walls and separated from the tongue portion by notches.

Claim 4

In an arrangement for connecting an electrical connector to a mating printed circuit board, the connector including a dielectric housing having top and bottom walls joined by spaced apart side walls, means defining an elongated slot between the top and bottom walls for receiving the mating printed circuit board, and a plurality of terminals mounted in the housing with contact portions along the slot for engaging contact pads on the circuit board, wherein the improvement comprises two pairs of aligned apertures passing through the top and bottom walls of the housing near opposite ends of the slot, a pair of apertures in the circuit board adapted for alignment with the two pairs of apertures in the housing when the circuit board is inserted into the slot, and a pair of fasteners adapted to be respectively received in the pairs of housing apertures and the respective aligned board apertures to maintain the board in mating relationship with the connector, the fastener being adapted to clamp against the top and bottom walls of the housing, and the width of the slot being greater than the thickness of the printed circuit board so that clamping forces of the fastener against the top and bottom walls of the housing are not transmitted to the printed circuit board, each pair of apertures in the top and bottom walls of the housing being located adjacent and outside a respective one of said side walls in the wing portions whereby the side walls provide reinforcement against the clamping forces of the fasteners, and the printed circuit board including a tongue portion insertable into said slot and a pair of end wing portions having apertures therein, the end wing portions being located outside the side walls and separated from the tongue portion by notches.
