1. An electrical connector comprising:

a housing; and

a plurality of first ground contacts connected to the housing, where the first ground contacts each comprise a first end configured to be connected to a first component and a second end, where the second end forms a male contact blade configured to be inserted into a contact channel of a housing of a mating electrical connector, where the male contact blade is configured to make a removable connection with a deflectable beam of a mating contact of the mating electrical connector,

where the male contact blade has a portion configured to contact the housing of the mating electrical connector during connection of the electrical connector to the mating electrical connector, after the male contact blade makes electrical contact with the deflectable beam, to move the male contact blade in the contact channel, increase deflection of the deflectable beam by the male contact blade, and increase or maintain normal force between the mating contact and the ground contact generally perpendicular to a direction of insertion of the male contact blade into the contact channel.

2. An electrical connector as in claim 1 where the portion comprises a lateral jog in a rear end of the male contact blade.

3. An electrical connector as in claim 1 where the ground contacts are formed from one or more sheet metal members such that the male contact blade has a cross sectionally flat shape, and where the portion comprises a bent portion of the cross sectionally flat shaped male contact blade.

4. An electrical connector as in claim 3 where the portion comprise a general lateral rounded hill shape.

5. An electrical connector as in claim 1 where the male contact blade is substantially straight except for the portion, where the portion extends laterally outward from a center axis of the substantially straight male contact blade between coaxially aligned front and rear sections of the male contact blade which are located on opposite ends of the portion.

6. An electrical connector as in claim 1 where the portion is sized and shaped to cause the male contact blade to pivotably deflect in a general cantilever fashion proximate a rear end of the male contact blade as the portion contacts and moves along the housing of the mating electrical connector.

7. An electrical connector as in claim 1 further comprising second signal contacts connected to the housing, where the signal contacts comprise male contacts blades at a same side of the housing as the male contacts blades of the first ground contacts, where the signal contacts and the ground contacts are formed from one or more sheet metal members having a same thickness such that the male contact blades of the first ground contacts and second signal contacts have a substantially same thickness.

8. An electrical connector as in claim 7 where the male contact blades of the second signal contacts are straight without the portion.

9. An assembly comprising:

an electrical connector as in claim 7 ; and

a mating electrical connector connected to the electrical connector, where the mating electrical connector comprises a housing with contact channels, and mating contacts with deflectable beams.

10. An assembly as in claim 9 where the mating contacts comprise mating ground contacts having their respective deflectable beams on only one side of the first ground contacts.

11. An electrical connector comprising:

a housing;

a plurality of ground contacts connected to the housing, where the ground contacts comprise first male contact blades; and

a plurality of signal contacts connected to the housing, where the signal contacts comprise second male contact blades at a same side of the housing as the first male contact blades, where the signal contacts and the ground contacts are formed from one or more sheet metal members having a same thickness such that the first and second male contact blades have a same thickness,

where, each of the first male contact blades have a portion configured to contact a housing of a mating electrical connector during connection of the electrical connector to the mating electrical connector which, after the first male contact blade makes electrical contact with a deflectable beam of a mating contact in the mating electrical connector and after a majority of insertion of the first male contact blade into the mating electrical connector, and during further insertion of the ground contact into the housing of the mating electrical connector contact, causes the first male contact blade to move in a direction to increase deflection of the deflectable beam and thereby increase or maintain normal force between the deflectable beam and the first male contact blade.

12. An electrical connector as in claim 11 where the portion comprises a lateral jog proximate a rear end of the first male contact blades.

13. An electrical connector as in claim 11 where the ground contacts have a cross sectionally flat shape, and where the portion comprises a bent portion of the cross sectionally flat shaped first male contact blade.

14. An electrical connector as in claim 13 where the portion comprise a general lateral extending arc shape.

15. An electrical connector as in claim 11 where the first male contact blade is substantially straight except for the portion, where the portion extends laterally outward from a center axis of the substantially straight first male contact blade between coaxially aligned front and rear sections of the first male contact blade which are located on opposite ends of the portion.

16. An electrical connector as in claim 11 where the portion is sized and shaped to cause the first male contact blade to pivotably deflect in a general cantilever fashion proximate a rear end of the first male contact blade as the portion contacts and moves along the housing of the mating electrical connector.

17. An electrical connector as in claim 11 where the second male contact blades of the signal contacts are straight without the portion.

18. An assembly comprising:

an electrical connector as in claim 11 ; and

a mating electrical connector connected to the electrical connector, where the mating electrical connector comprises a housing with contact channels, and mating contacts with deflectable beams.

19. An assembly as in claim 18 where the mating contacts comprise mating ground contacts having their respective deflectable beams on only one side of the first ground contacts.

20. A method comprising:

inserting first male contact blades of a plurality of ground contacts of a first electrical connector into first contact channels of a second electrical connector; and

inserting second male contact blades of a plurality of signal contacts of the first electrical connector into second contact channels of the second electrical connector,

where the ground and signal contacts are formed from one or more sheet metal members having a same thickness such that the first and second male contact blades have a substantially same thickness,

where, after the first and second male contact blades have moved deflectable beams of mating contacts of the second electrical connector and slid along the deflectable beams along a majority of length of the first and second male contact blades, a portion of the first male contact blades contacts a housing of the second electrical connector and, with further insertion of the first male contact blade into the second electrical connector, the portion and the housing cause the first male contact blade to deflect and move the respective deflectable beams to increase or maintain normal force.

21. An electrical connector comprising:

a housing; and

a plurality of first contacts connected to the housing, where the first contacts each comprise a first end configured to be connected to a first component and a second end, where the second end forms a male contact blade configured to be inserted into a contact channel of a housing of a mating electrical connector, where the male contact blade is configured to make a removable connection with a deflectable beam of a mating contact of the mating electrical connector,

where the male contact blade has a portion configured to contact the housing of the mating electrical connector during connection of the electrical connector to the mating electrical connector, after the male contact blade makes electrical contact with the deflectable beam, to move the male contact blade in the contact channel, increase deflection of the deflectable beam by the male contact blade, and increase or maintain normal force between the mating contact and the contact generally perpendicular to a direction of insertion of the male contact blade into the contact channel.
