Abstract

An electrical connector (1) comprising: an insulative housing (2), multiple pairs (3) of conductive signal contacts (4, 5) distributed along an insulative divider (7) within the housing (2) and adapted to be connected to respective pairs of signal wires (27), at least one conductive power contact (6) having a pair of contact fingers (9) on opposite sides of the divider, (7), the contact fingers (9) having a surface area sufficiently broad to radiate heat resulting from electrical power dissipation.

Claims

1. An electrical connector comprising:

an insulative housing, multiple pairs of conductive signal contacts distributed along an insulative divider within an interior of the housing, the divider separating one of the signal contacts from the other of the signal contacts of each pair, and at least one conductive power contact having a pair of contact fingers on opposite sides of the divider, the contact fingers having a surface area sufficiently broad to radiate heat from electrical power dissipation, and the fingers extending parallel to the signal contacts in the cavity.

2. An electrical connector as recited in claim 1, comprising:

the fingers being connected to a body portion having a surface area sufficiently broad to radiate heat from electrical power dissipation, a pocket in the housing behind the divider receiving the body portion, and contact receiving cavities in the housing behind the divider receiving the contacts, each of the cavities being smaller than the pocket.

3. An electrical connector as recited in claim 1 wherein each of the fingers is of greater mass than each of the signal contacts.

4. An electrical connector as recited in claim 2, comprising:

the body portion having a thickness, and the contact fingers having the same thickness, and the fingers being bent to extend outward from the body such that the thickness of the body is in a plane perpendicular to a plane of each thickness of the contact fingers.

5. An electrical connector as recited in claim 4, comprising:

arms extending laterally of each body portion, the arms being bendable to encircle and connect with an electrical wire.

6. An electrical connector as recited in claim 1, wherein the signal contacts are distributed along opposite sides of the divider.

7. An electrical connector as recited in claim 1, wherein each pair of signal contacts are on opposite sides of the divider and are connected to a twisted pair of signal wires, and the fingers of the power contact are on opposite sides of the divider and are connected to a single wire larger in diameter than each of the signal wires.

8. An electrical connector as recited in claim 7 wherein each of the fingers is of greater mass than each of the signal contacts.

9. An electrical connector as recited in claim 7, comprising:

the fingers being connected to a body portion having a surface area sufficiently broad to radiate heat from electrical power dissipation,

the body portion having a thickness, and the contact fingers having the same thickness, and the fingers being bent to extend outward from the body such that the thickness of the body is in a plane perpendicular to a plane of each thickness of the contact fingers.

10. An electrical connector as recited in claim 7, comprising:

arms extending laterally of each body portion, the arms being bendable to encircle and connect with an electrical wire.

11. An electrical connector as recited in claim 7, wherein the signal contacts are distributed along opposite sides of the divider.

12. An electrical connector comprising:

an insulative housing, multiple pairs of conductive signal contacts distributed along an insulative divider within an interior of the housing and adapted to be connected to respective pairs of signal wires, at least one conductive power contact having a pair of contact fingers on opposite sides of the divider, the contact fingers having a surface area sufficiently broad to radiate heat from electrical power dissipation, and the fingers of the power contact are on opposite sides of the divider and are connected to a wire larger in diameter than each of the signal wires.

13. An electrical connector as recited in claim 12, wherein, each pair of signal contacts are on opposite sides of the divider.

14. An electrical connector as recited in claim 12, wherein the fingers are parallel to the signal contacts.
