Embodiments of electrical connectors include features that facilitate circulation of air through and around the electrical connectors. The air can cool the power contacts of the electrical connectors, thereby allowing the power contacts to operate at higher currents that would otherwise be possible.

The connector system of claim 1, wherein a another aperture is formed in the first housing and is aligned with the first aperture and the mating portion of the first power contact, whereby air heated by the first power contact can circulate over the mating portion of the first power contact by way of the apertures. 3. The electrical connector system of claim 1, wherein the first aperture of the first electrical connector overlaps with the second aperture of the second electrical connector when the first and second electrical connectors are mated together. 4. The electrical connector system of claim 1, wherein the first electrical connector further comprises the third power contact. 5. The connector system of claim 1, wherein the first power contact comprises a terminal pin that engages the substrate, and a portion of the terminal pin is located within the first recess formed in the bottom portion of the first housing. 6. The connector system of claim 5, wherein the first power contact further comprises a plate-like body member and a substantially S-shaped portion that adjoins the body member and the terminal pin, wherein the a portion of the S-shaped portion is located within the first recess. 7. The connector system of claim 1, wherein the first power contact comprises a plurality of contact beams and the first aperture is aligned with the contact beams. 8. The connector system of claim 7, wherein the contact beams are located in a cavity defined by the first housing and the first aperture places the cavity in fluid communication with the environment around the first electrical connector. 9. The connector system of claim 8, wherein the first aperture is located above the contact beams, and another aperture is formed in the first housing below the contact beams whereby air can circulate through the cavity and over the contact beams by way of the apertures. 10. The connector system of claim 8, wherein the first aperture facilitates air circulation in a first direction, and the first recess facilitates air circulation in a second direction substantially perpendicular to the first direction. 11. The connector system of claim 10, wherein an end of the cavity is in fluid communication with the environment around the first electrical connector, and the cavity extends substantially in a third direction substantially perpendicular to the first and second directions whereby the cavity facilitates air circulation in the third direction. 12. An electrical connector, comprising: an electrically insulative housing; and a first power contact mounted in the housing and having a mating portion, wherein the housing has an aperture formed therein and aligned with the mating portion of the first contact whereby air heated by the power contact can exit the power contact by way of the aperture; and a second power contact, wherein (i) each power contact comprises a tab, (ii) the housing comprises a first and a second cavity formed therein that receive the respective first and second power contacts, and (iii) the tab of the first power contact interferedly contacts the housing when the first power contact is partially inserted into the second cavity thereby preventing installation of the first power contact in the second cavity, and the tab of the second power contact interferedly contacts the housing when the second power contact is partially inserted into the first cavity thereby preventing installation of the second power contact in the first cavity. 13. The electrical connector of claim 12, configured to mate with a corresponding connector such that the aperture overlaps with a complementary aperture of the corresponding connector. 14. The electrical connector of claim 12, wherein (i) a passage is defined by the housing and a substrate when the electrical connector is mounted on the substrate, (ii) the passage extends from a first side of the housing to an opposite second side of the housing, (iii) a portion of the power contact extends into the passage, (iv) at least a portion of the aperture terminates at the passage, and (v) whereby air from the environment around the electrical connector can pass between the housing and substrate and over the power contact. 15. The electrical connector of claim 12, wherein the housing has a top portion having the aperture formed therein, and a bottom portion having another aperture formed therein and aligned with the mating portion of the contact. 16.
