Abstract

A plug connector is disclosed that has a body portion and a circuit card extending forwardly of a mating face of the connector. The circuit card is protected in place by one or more protective flanges that extend forwardly from the body portion and which flank the circuit card to protect it from stubbing and to provide a means for aligning the plug connector with the receptacle connector. The body portion has a hollow frame that supports the circuit card and the interior of the frame is filled with a molding material, such as plastic.

Claims

1. A plug connector for connecting wires to a mating connector, comprising:

a connector housing, the connector housing including an insulative body portion, the connector housing body portion including a forward face;

a circuit card, the circuit card including a leading edge with contacts for mating with the mating connector and a trailing edge with contacts for termination to a plurality of wires, said circuit card being disposed in said connector housing such that the circuit card leading edge extends forwardly of the connector body portion forward face for a preselected length and the circuit card trailing edge being disposed within said connector housing;

a plurality of wires terminated to the circuit card trailing edge contacts;

said connector housing body portion including a first flange extending a first preselected distance from said connector housing body portion and spaced apart from said circuit card, and a second flange extending a second preselected distance from said connector housing body portion and spaced apart from said circuit card; and

,

said connector housing body portion including a front wall and two side walls, the front wall defining said connector housing body portion forward face and the two side walls defining a hollow termination nest between themeselves and rearwardly of said front wall, said circuit card trailing edge being disposed in the termination nest and said wires being terminated to said circuit card trailing edge contacts in said termination nest.

2. The plug connector of claim 1, wherein said connector housing body portion is partially overmolded to fill said termination nest with a moldable insulative material and enclose said wire terminations in the moldable material.

3. The plug connector of claim 1, wherein said connector housing body portion includes a longitudinal slot that receives at least one side edge of said circuit card and said connector housing body portion includes a transverse slot through which said circuit card extends to expose said circuit card leading edge forwardly of said connector housing body portion forward face.

4. The plug connector of claim 1, wherein said second flange extends a second preselected distance from said connector housing body portion forward face and is spaced apart from said the first flange, said first and second flanges flanking said circuit card.

5. The plug connector of claim 4, wherein said first flange first preselected distance is greater than said second flange second preselected distance.

6. The plug connector of claim 1, wherein said circuit card leading edge and first and second flanges all have respective widths, the width of said circuit card leading edge being less than the width of said first flange but greater than the width of said second flange.

7. The plug connector of claim 1, wherein said first flange includes an angled lead-in configuration along side edges thereof.

8. The plug connector of claim 1, wherein said connector housing body portion includes means for registering it with an guide member associated with a mating connector, the registration means including a T-shaped projection.

9. The plug connector of claim 8, wherein each of said connector housing body portion two sidewalls includes a T-shaped projection disposed on an outer surface thereof.

10. The plug connector of claim 3, wherein said connector housing body portion includes at least one stop member and said circuit card includes at least one card-locating shoulder formed therein, the stop member contacting the circuit card to locate said circuit card in place within said connector housing.

11. The plug connector of claim 10, wherein said connector housing body portion includes a pair of stop members and said circuit card includes a pair of card-locating shoulders, the card-locating shoulders being disposed along two opposing side edges of said circuit card, said stop members limiting the distance said circuit card projects through said transverse slot.

12. The plug connector of claim 2, wherein said circuit card has a notch formed therein that permits the flow on moldable material to areas of said termination nest on opposite sides of said circuit card.

13. The plug connector of claim 1, further including a pre-formed cover portion that fits over and closes off said termination nest.

14. A plug connector for connecting wires to a mating connector, comprising:

a connector housing, the connector housing including an insulative body portion, the connector housing body portion including a forward face;

a circuit card, the circuit card including a leading edge with contacts for mating with the mating connector and a trailing edge with contacts for termination to a plurality of wires, said circuit card being disposed in said connector housing such that the circuit card leading edge extends forwardly through the connector body portion forward face for a preselected length and the circuit card trailing edge extends rearwardly within said connector housing;

a plurality of wires terminated to the circuit card trailing edge contacts;

said connector housing body portion including a first flange extending a first preselected distance from said connector housing body portion and spaced apart from said circuit card, and a second flange extending a second preselected distance from said connector housing body portion and spaced apart from said circuit card; and

,

said connector housing body portion including a front wall and two side walls, the front wall defining said connector housing body portion forward face and the two side walls defining a hollow termination nest between themselves and rearwardly of said front wall, said circuit card trailing edge being disposed in the termination nest and said wires being terminated to said circuit card trailing edge contacts in said termination nest, said side walls including longitudinal slots that receives side edges of said circuit card therein, and said connector housing body portion includes a transverse slot through which said circuit card extends to expose said circuit card leading edge forwardly of said connector housing body portion forward face.

15. The plug connector of claim 14, wherein said connector housing is partially overmolded to fill said termination nest with a moldable insulative material and enclose said wire terminations in the moldable material.

16. The plug connector of claim 14, wherein said second flange extends a second preselected distance from said connector housing body portion forward face and is spaced apart from said the first flange, said first and second flanges flanking said circuit card.

17. The plug connector of claim 16, wherein said first flange first preselected distance is greater than said second flange second preselected distance.

18. The plug connector of claim 14, wherein said circuit card leading edge and first and second flanges all have respective widths, the width of said circuit card leading edge being less than the width of said first flange but greater than the width of said second flange.
