A first contact beam of a receptacle contact may define an indentation and a second contact beam may define a protrusion such that the protrusion may at least partially extend into the indentation. The protrusion may extend across the center of the receptacle contacts, and therefore the normal force created by each contact beam may be exerted against the normal force created by the other contact beam. Thus, rotation of a blade contact inserted into the receptacle contact may be reduced or eliminated. The contact beams of the receptacle contact may each include a formed area placed at different locations on the receptacle contact. A blade contact may overcome the normal force and mechanical resistance of a formed area of one of the contact beams before being confronted by the normal force and mechanical resistance of the other beam's formed area.

What is claimed: 1. An electrical connector, comprising: a contact block; and a receptacle contact received in the contact block, said receptacle contact comprising first and second contact beams that each extend along a first direction, the receptacle contact defining a center reference line between the first and second contact beams in the first direction, wherein (i) the first contact beam is opposed to the second contact beam in a second direction and is offset from the second contact beam in a third direction perpendicular to the first and second directions, (ii) the first contact beam defines a first indentation and the second contact beam defines a second protrusion at least partially extending toward the first indentation in the third direction and beyond the center reference line such that the protrusion is at least partially received in the first indentation, the second protrusion for contacting a contact element received between the first and second contact beams of the receptacle contact, and (iii) the second contact beam defines a second indentation and the first contact beam defines a first protrusion at least partially extending toward the second indentation, the first protrusion for contacting the contact element. 2. The electrical connector of claim 1, wherein the receptacle contact extends in the first direction from the contact block, and wherein the contact block defines a shape such that the first protrusion is located a first distance in the first direction from the contact block and the second protrusion is located a second distance in the first direction from the contact block. 3. The electrical connector of claim 1, wherein the first contact beam defines a first formed area extending toward the second contact beam, the first formed area for contacting the contact element. 4. The electrical connector of claim 3, wherein the first protrusion is at least partially within the first formed area. 5. The electrical connector of claim 1, wherein the receptacle contact is formed from a single sheet of conductive material. 6. The electrical connector of claim 1, further comprising a second receptacle contact, wherein the contact block provides a first normal force to the receptacle contact and a second normal force to the second receptacle contact. 7. The electrical connector of claim 6, wherein the first normal force is approximately equal to the second normal force. 8. An electrical connector, comprising: a contact block; and a receptacle contact received in the contact block, defining a first contact beam and a second contact beam that each extend along a first direction, wherein (i) the first contact beam is opposed to the second contact beam in a second direction and is offset from the second contact beam in a third direction perpendicular to the first and second directions, (ii) the first contact beam defines a first formed area extending toward the second contact beam in the second direction, and further defines a first indention, and the second contact beam defines a second formed area extending toward the first contact beam and further defines a second protrusion extending toward the first indention in the third direction, (iii) the second contact beam further defines a second indentation and the first contact beam further defines a first protrusion extending at least partially toward the second indentation, and (iv) the first formed area is located to receive a blade contact inserted between the first and second contact beams such that the blade contact abuts the first formed area before abutting the second formed area. 9. The electrical connector of claim 8, wherein the first protrusion is at least partially located within the first formed area of the first contact beam. 10. The electrical connector of claim 8, wherein the receptacle contact is formed from a single sheet of conductive material. 11. The electrical connector of claim 8, wherein the first formed area is located to receive a rectangular blade contact. 12. The electrical connector of claim 8, wherein the receptacle contact extends in the first direction from the contact block, and wherein the contact block defines a shape such that the first formed area is located a first distance in the first direction from the contact block and the second formed area is located the first distance in the first direction from the contact block. 13. The electrical connector of claim 8, wherein the contact block defines a well and wherein the second contact beam is received in the well. 14. An electrical connector, comprising: a contact block; and a receptacle contact received in the contact block, said receptacle contact comprising first and second contact beams that extend along a first direction, wherein (i) the first contact beam is opposed to the second contact beam in a second direction and is offset from the second contact beam in a third direction perpendicular to the first and second directions, (ii) a portion of the first contact beam overlaps with a portion of the second contact beam in the third direction, (iii) the first contact beam includes a first formed area that is curved and protrudes toward the second contact beam, and the second contact beam includes a second formed area that is curved and protrudes toward the first contact beam, (iv) both the first formed area and the second formed area intersect a common line about the second direction, (v) the first and second formed areas are formed such that, as a contact element is inserted between the first and second contact beams, the contact element at least partially overcomes a normal force exerted by the first contact beam before the second contact beam exerts a normal force on the contact element, and (vi) the normal force exerted by the first contact beam is in the second direction. 15. The electrical connector of claim 14, wherein the first contact beam defines a first indentation and the second contact beam defines a second protrusion at least partially extending toward the first indentation, the second protrusion for contacting the contact element received in the receptacle contact.
