Abstract

A receptacle assembly includes a main housing having a header interface end configured to mate with a header assembly. The main housing has a board reception end that retains a plurality of electrical contacts arranged in at least two parallel rows. At least two rows of the electrical contacts are configured to contact one surface of a circuit card while at least one row of electrical contacts is configured to contact an opposite surface of the circuit card. The receptacle assembly may also include at least one ground shield that at least partially covers the main housing.

Claims

1. An electrical connector, comprising a header assembly configured to be mounted on a first circuit board and a receptacle assembly configured to mate with a second circuit board, said receptacle assembly comprising:

a main housing including a top surface, a bottom surface, a header interface end having a plurality of contact cavities, and a board reception end having a plurality of contact receptacles, each of said contact receptacles communicating with a corresponding one of said contact cavities;

a plurality of electrical contacts retained within said contact receptacles;

a ground contact retained within one of said contact receptacles

a first ground shield having a first shield strip overlying one of said top and bottom surfaces; and

a ground clasp formed integrally with said first shield strip, said ground clasp extending from said first shield strip and engaging said ground contact.

2. The electrical connector of claim 1, further comprising a second ground shield having a second shield strip overlying another of said top and bottom surfaces, said second shield strip including a ground tail extending outwardly from said second shield strip, said ground tail being aligned with the second circuit board.

3. The electrical connector of claim 1, wherein said ground clasp is bent downward to extend into alignment with a corresponding one of said plurality of contact receptacles, said ground clasp interconnecting said first shield strip to said ground contact extending outwardly from said one of said plurality of contact receptacles.

4. The electrical connector of claim 1, wherein said electrical contacts are aligned in at least a first row, said ground contact being aligned in said first row of said electrical contacts.

5. The electrical connector of claim 1, wherein each of said plurality of electrical contacts includes a retained portion integrally formed with a contact tail, each of said contact tails extending outwardly from one of said plurality of contact receptacles, and each of said retained portions being housed within one of said plurality of contact cavities.

6. The electrical connector of claim 1, wherein said plurality of electrical contacts are arranged in at least two parallel rows and are configured such that the first circuit board is sandwiched between said at least two parallel rows.

7. The electrical connector of claim 1, wherein said first ground shield includes housing securing members that fold over side portions of said main housing.

8. The electrical connector of claim 1, wherein said header assembly is one of a right-angled and straight header assembly.

9. A receptacle assembly, comprising:

a main housing having a header interface end configured to mate with a header assembly, said main housing having a board reception end that retains a plurality of electrical contacts arranged in at least three parallel rows, wherein at least two rows of said electrical contacts are configured to contact one surface of a circuit card while at least one row of said electrical contacts is configured to contact an opposite surface of the circuit card; and

at least one ground shield at least partially covering said main housing, said at least one ground shield being formed integrally with a ground contact that directly engages a ground pad on the circuit card.

10. The receptacle assembly of claim 9, wherein said at least two rows of electrical contacts include first and second contact tails that are spaced first and second different distances from said board interface end to engage first and second rows of contact pads on the circuit card.

11. The receptacle assembly of claim 9, wherein said at least one ground shield includes housing securing members that fold over side portions of said main housing.

12. The receptacle assembly of claim 9, wherein said at least one ground shield includes a shield strip, said shield strip includes a ground clasp formed integrally therewith, said ground clasp engaging a ground contact retained within said main housing.
