Abstract

An electrical power interconnection system is described. The electrical interconnection system may comprise an electrical power connector and a substrate, such as a printed circuit board. The electrical power connector may comprise a housing and a plurality of electrical power contacts supported by the housing. The electrical power contacts may comprise a mounting end, a mating end, and a contact body disposed between the mounting end and the mating end. The electrical power contacts may have planar portions. The mating ends may comprise opposing first second beams defining a slot. The slot may be configured to receive the substrate therein, such that the first beam contacts the first side of the substrate and the second beam contacts the second side of the substrate.

First claim

The invention claimed is:

1. An electrical power connector comprising:
an electrically insulative connector housing that defines a mating interface, wherein the mating interface further defines a slot, the connector housing further defining a mounting interface;
a plurality of electrical power contacts supported by the connector housing and spaced along a longitudinal direction, each of the electrical power contacts defining a mating end disposed proximate to the mating interface, a mounting end that is opposite the mating end and disposed proximate to the mounting interface, and a contact body that extends from the mating end to the mounting end, the plurality of electrical power contacts being planar and disposed perpendicularly with respect to the longitudinal direction; and
wherein each of the mating ends includes a first beam that extends from the contact body and a second beam that extends from the contact body, the first beam and the second beam disposed at opposed sides of the slot with respect to a transverse direction that is perpendicular to the longitudinal direction, such that a first substrate is configured to be received between the first beams of the electrical power contacts and the second beams of the electrical power contacts along a lateral direction that is perpendicular to each of the transverse direction and the longitudinal direction,
wherein the electrical power contacts comprise a first group of electrical power contacts alternating, along the longitudinal direction, with a second group of electrical power contacts, and wherein the mounting ends of the first group of electrical power contacts are spatially offset, along the lateral direction, relative to the mounting ends of the second group of electrical power contacts,
wherein mounting ends of electrical power contacts of the first group are adjacent to mounting ends of electrical power contacts of the second group; and
wherein each electrical power contact of the first group has a first number of mounting ends and each electrical power contact of the second group has a second number of mounting ends, wherein the first number is different from the second number.

2. An electrical power connector as recited in claim 1 , wherein the plurality of electrical power contacts are spaced equidistantly along the longitudinal direction.

3. The electrical power connector as recited in claim 1 , wherein, when the substrate is received in the slot, the first beam is configured to form a first electrical contact with a first pad disposed on a first surface of the substrate.

4. The electrical power connector as recited in claim 3 , wherein, when the substrate is received in the slot, the second beam is configured to form a second electrical contact with a second pad disposed on a second surface, opposite the first surface, of the substrate.

5. The electrical power connector as recited in claim 1 , wherein the mounting ends of electrical power contacts of the first group and the mounting ends of the electrical power contacts of the second group are adjacent to a common side of the electrically insulative connector housing that is opposite the mating interface.

6. The electrical power connector as recited in claim 1 , wherein the plurality of electrical power contacts are spaced, along the longitudinal direction, by a distance that is between approximately 0.7 mm and approximately 2 mm.

7. The electrical power connector of claim 1 , wherein each of the first and second beams comprises a first edge and a second edge opposite the first edge, the first and second edges being configured, when the substrate is received in the slot, to contact respectively a first pad, disposed on a first surface of the substrate, and a second pad, disposed on a second surface of the substrate opposite the first surface.

8. The electrical connector of claim 1 , wherein the mounting ends of the first group of electrical power contacts are offset with respect to the mounting ends of the second group of electrical power contacts along the lateral direction.

9. An electrical power connector comprising:
an electrically insulative connector housing that defines a mating interface, wherein the mating interface further defines a slot, the connector housing further defining a mounting interface;
a plurality of electrical power contacts supported by the connector housing and spaced along a longitudinal direction, each of the plurality of electrical power contacts defining a mating end disposed proximate to the mating interface, a mounting end that is opposite the mating end and disposed proximate to the mounting interface, and a contact body that extends from the mating end to the mounting end, each of the plurality of electrical power contacts having a portion that is planar and is disposed perpendicularly with respect to the longitudinal direction;
wherein each of the mating ends includes a first beam that extends from the contact body and a second beam that extends from the contact body, the first beam and the second beam are disposed at opposed sides of the slot with respect to a transverse direction that is perpendicular to the longitudinal direction, such that a first substrate is configured to be received between the first and second beams along a lateral direction that is perpendicular to each of the transverse direction and the longitudinal direction,
wherein each of the first and second beams includes a first beam portion and a second beam portion, the first beam portion being disposed between the second beam portion and the contact body along the lateral direction, the second beam portion being wider than the first beam portion along the transverse direction, and
wherein a ratio between a width of the first beam portion and a width of the second beam portion is between 0.3 and 0.45.

10. The electrical power connector as recited in claim 9 , wherein the first beam portion has a width that is between approximately 0.3 mm and approximately 0.7 mm.

11. The electrical power connector as recited in claim 9 , wherein the first beam portion has a length that is between approximately 2 mm and approximately 4 mm.

12. The electrical power connector as recited in claim 9 , wherein a ratio between a length of the first beam portion and a length of the second beam portion is between 0.3 and 0.55.

13. An electrical power connector comprising:
an electrically insulative connector housing that defines a mating interface, wherein the mating interface further defines a slot, the connector housing further defining a mounting interface;
a plurality of electrical power contacts supported by the connector housing and spaced along a longitudinal direction, each of the plurality of electrical power contacts defining a mating end disposed proximate to the mating interface, a mounting end disposed proximate to the mounting interface, and a contact body that extends from the mating end to the mounting end, each of the plurality of electrical power contacts having a portion that is planar and is disposed perpendicularly with respect to the longitudinal direction;
wherein each of the mating ends includes a first beam that extends from the contact body and a second beam that extends from the contact body, the first beam and the second beam are disposed at opposed sides of the slot with respect to a transverse direction that is perpendicular to the longitudinal direction, such that a first substrate is configured to be received between the first and second beams along a lateral direction that is perpendicular to each of the transverse direction and the longitudinal direction,
