Abstract

A circular power connector that can accommodate plugs of varying diameters includes a plurality of electrical terminals that include a contact beam extending from and monolithic with base, where the contact beam includes a contact portion, and a mounting portion that extends from and monolithic with a base for mounting the terminal to a substrate. The terminals are cylindrically arranged to receive a plug. Alternatively, each electrical terminal includes a frame portion, a first contact beam extending from the frame in a first direction, and a second contact beam extending from the frame in a second direction. Multiple electrical terminals are oriented so that the first and second contact beams for one terminal extend at an angle, preferably perpendicular, to the first and second contact beams of another electrical terminal, in a still further embodiment, an electrical terminal having two halves is provided.

First claim

What is claimed:

1. An electrical connector, comprising:
a housing; and
a plurality of terminals supported by the housing, at least two of said plurality of terminals comprise:
an electrically conductive base;
a contact beam that extends from said base and is monolithic with said base, said contact beam including a contact portion; and
a mounting portion that extends from said base and is monolithic with said base for mounting said terminal to a substrate, wherein at least a portion of the mounting portion extends from the housing to form an interface to the substrate;

wherein:
said plurality of terminals are arranged cylindrically around an insertion axis to form a receptacle for receiving a plug therein, wherein:
contact portions of said at least two terminals face said insertion axis and any two of said at least two terminals lie on a chord across said receptacle; and
the chord intersects the electrical connector only at the two terminals.

2. The electrical connector as recited in claim 1 , wherein the mounting portion is configured as a press fit tail.

3. The electrical connector of claim 1 , wherein the mounting portion extends away from said respective base in a direction generally opposite said contact beam.

4. The electrical connector of claim 1 , wherein the mounting portion curves away from the respective base at an angle.

5. The electrical connector of claim 1 , wherein the contact beam extends from the base in a first direction, and the mounting portion extends from the base in a second direction opposite the first direction.

6. The electrical connector of claim 1 , wherein the contact beam extends from the base in a first direction, and the mounting portion extends from the base in the first direction.

7. The electrical connector of claim 1 , further comprising a solder ball positioned proximate said mounting portion, for electrically connecting said base to a substrate.

8. The electrical connector of claim 1 , wherein each of the at least two of said electrical terminals further comprise an insertion portion on the end of said contact portion furthest from said base, wherein said insertion portion includes a first side and a second side, wherein said first side is at an angle relative to said second side.

9. An electrical connector comprising:
an electrically insulative connector housing defining a receiving chamber configured to receive a cylindrical plug, the receiving chamber bound by an insulative wall of the housing; and
a plurality of electrical terminals supported by the connector housing, each of the plurality of electrical terminals including:
a base;
a contact beam extending from said base, said contact beam including a contact portion; and
a mounting portion that extends from said base and is monolithic with said base for mounting said terminal to a substrate;
wherein at least a portion of the terminal is disposed within said insulative wall and at least a portion of said contact portion extends from said insulative wall into said chamber.

10. The electrical connector of claim 9 , wherein the contact beam further includes an insertion portion having first and second sides, said housing defines an opening to said receiving chamber, and said plurality of terminals are positioned in said housing so that said insertion portions are positioned proximate said opening wherein the distance between said first and second sides of said insertion portions become greater along said insertion portion in a direction from said opening toward said base.

11. The electrical connector of claim 10 , where said housing defines an angled surface surrounding said opening.

12. The electrical connector of claim 9 , wherein said receiving chamber defines an insertion axis and wherein said beam extends away from said base at an angle towards said insertion axis.

13. The electrical connector of claim 9 , wherein said contact portion includes a first contact side and a second contact side, wherein said first contact side is at an angle relative to said second contact side wherein the distance between said first and second contact sides becomes greater along said contact portion in a direction away from said base.

14. The electrical connector of claim 13 , wherein the first contact side is linear along a direction away from the base.

15. The electrical connector of claim 14 , wherein the second contact side is linear along a direction away from the base.

16. The electrical connector of claim 9 , wherein each of the at least some electrical terminals further includes an insertion portion positioned at an end of said contact portion furthest from said base, wherein said insertion portion includes a first insertion side and a second insertion side, wherein said first insertion side is at an angle relative to said second insertion side.

17. The electrical connector of claim 9 , wherein said housing comprises a base portion and a central portion extending from said base portion.

18. The electrical connector of claim 16 , wherein the distance between said first and second insertion sides becomes smaller along said insertion portion in a direction away from said base.

19. The electrical connector of claim 16 , wherein the first insertion side is linear along a direction away from the base.

20. The electrical connector of claim 16 , wherein the second insertion side is linear along a direction away from the base.

21. The electrical connector of claim 18 , wherein said first insertion side has an arcuate shape oriented so that the distance between said first and second sides becomes smaller in a direction away from said base.

22. The electrical connector of claim 17 , wherein said central portion includes a frustoconical surface.

23. An electrical connector comprising:
an electrically insulative connector housing defining a receiving chamber configured to receive a cylindrical plug, the receiving chamber bound by an insulative wall; and
a plurality of electrical terminals supported by the connector housing, each of said plurality of electrical terminals including:
a base;
