Abstract

Electrical connectors and contacts for transmitting power are provided. One power contact embodiment includes a first plate that defines a first non-deflecting beam and a first deflectable beam, and a second plate that defines a second non-deflecting beam and a second deflectable beam. The first and second plates are positioned beside one another to form the power contact.

Claims

1. An electrical connector system comprising:

a first electrical connector comprising a first housing, and a first plurality of electrical contacts disposed in the first housing, the housing defining a first plurality of apertures extending therethrough; and

a second electrical connector comprising a second housing, and a second plurality of electrical contacts disposed in the second housing, the housing defining a second plurality of apertures extending therethrough,

wherein (i) a first aperture of the first plurality of apertures extends through the first housing above a first contact of the first plurality of electrical contacts, (ii) a second aperture of the first plurality of apertures extends through the first housing below the first contact of the first plurality of electrical contacts, (iii) a third aperture of the second plurality of apertures extends through the second housing above a second contact of the second plurality of electrical contacts, (iv) a fourth aperture of the second plurality of apertures extends through the second housing below the second contact of the second plurality of electrical contacts, (v) the first aperture is aligned with the third aperture when the first electrical connector is mated with the second electrical connector, and (vi) the second aperture is aligned with the fourth aperture when the first electrical connector is mated with the second electrical connector.

2. The electrical connector system of claim 1 wherein the first housing has a mating face and the first plurality of apertures extend through the first housing proximate to the mating face.

3. The electrical connector system of claim 1 wherein the second housing has a mating face and the second plurality of apertures extend through the second housing proximate to the mating face.

4. The electrical connector system of claim 1 wherein the first and second plurality of electrical contacts are power contacts.

5. The electrical connector system of claim 1 wherein the first electrical connector is a header connector and the second electrical connector is a receptacle connector.

6. The electrical connector system of claim 1 wherein the apertures of the first and second plurality of apertures are heat dissipation apertures.

7. The electrical connector system of claim 1, wherein at least one of the apertures is aligned with a respective electrical contact.

8. The electrical connector system of claim 7, wherein each of the apertures is aligned with a respective electrical contact.

9. An electrical connector comprising:

a housing defining an aperture extending vertically therethrough at a location proximate to a mating face of the housing; and

an electrical contact retained in the housing, the electrical contact defining a contact blade disposed proximate to the mating face of the housing,

wherein the aperture is vertically aligned with the contact blade so as to allow heat from the contact blade to freely dissipate through the aperture after the electrical connector has been mated with a second electrical connector.

10. The electrical connector of claim 9, wherein the aperture is disposed above the contact blade.

11. The electrical connector of claim 9 wherein the electrical connector is a female connector.

12. The electrical connector of claim 9 wherein the electrical connector is a male connector.

13. The electrical connector of claim 9 wherein the housing defines a second aperture extending through the housing, wherein the second aperture is disposed below the contact blade and aligned with the contact blade.

14. The electrical connector of claim 9 wherein the electrical contacts are power contacts.

15. The electrical connector of claim 9, wherein the aperture extends through the housing in a first direction, and the electrical contact extends toward the mating face in a second direction that is perpendicular to the first direction.

16. The electrical connector of claim 9, wherein the aperture is substantially unobstructed after the electrical connector has been mated with the second electrical connector.

17. The electrical connector of claim 9, wherein the aperture is aligned with an aperture of the second electrical connector after the electrical connector is mated with the second electrical connector.

18. An electrical connector configured to mate with a second electrical connector, the electrical connector comprising:

a housing defining mating face and a mating interface disposed proximate to the mating face, the housing defining an aperture extending vertically therethrough into the mating interface; and

an electrical contact retained in the housing, the electrical contact having a contact portion disposed in the mating interface,

wherein the aperture remains unobstructed by a housing of the second electrical connector after the electrical connector has been mated with the second electrical connector such that heat from the contact portion of the electrical contact and heat from a mated contact of the second electrical connector can freely dissipate through the aperture.

19. The electrical connector of claim 18, wherein the heat from the contact portion and heat from the mated contact flow vertically into the mating interface prior to dissipating through the aperture.

20. The electrical connector of claim 18, wherein the aperture is aligned with the contact portion.
