Abstract

A power contact includes a fixing portion, an engaging arm extending backwardly from a front end of the fixing portion along a first direction and a support member extending towards the engaging arm. The support member is positioned between the engaging arm and the fixing portion along a second direction perpendicular to the first direction. The support member is adapted for abutting against the engaging arm so as to increase insertion/withdraw force and avoid over deformation of the engaging arm.

First claim

What is claimed is:

1. A power contact comprising:
a fixing portion extending in a front-to-back direction, each of the fixing portion defining a front end;
an engaging arm extending backwardly and slantwise from the front end of the fixing portion, the engaging arm having a front arm extending backwardly from the front end of the fixing portion and being obliquely away from the fixing portion, a rear arm connecting with the front arm and being bent toward the fixing portion and a contact portion formed at a boundary of the front arm and the rear arm; and
a support member stamped from the fixing portion and extending forwardly and inwardly towards the engaging arm, wherein the support member is a cantilevered arm having an engaging portion at a distal end thereof, the engaging portion being disposed between the rear arm and the fixing portion in such a manner that the engaging portion is correspondingly aligned with the rear arm of the engaging arm in an inward-to-outward direction perpendicular to the fixing portion, and wherein the engaging portion is adapted for abutting against the rear arm.

2. The power contact as claimed in claim 1 , wherein the power contact is of a symmetrical configuration with a base portion in a shape of sheet and defines an up-to-down direction, the fixing portion being a pair of the fixing portions bent perpendicularly from a pair of linear side of the base portion near an up end thereof, the engaging arm being a pair of the engaging arms extending backwardly from a front ends of the fixing portions, respectively, the support member being a pair of the support members stamped from the pair of fixing portions, respectively.

3. The power contact as claimed in claim 2 , further comprising a soldering portion extending downwardly from the base portion.

4. A power contact essentially of a symmetrical configuration and comprising:
a base portion, which is in a shape of sheet and defines an up-to-down direction and an up end thereof;
a pair of fixing portions arranged in parallel relationship with each other, which are bend perpendicularly from a pair of linear side of the base portion near the up end thereof and extend in a front-to-rear direction perpendicular to the up-to-down direction, each of the fixing portion defining a front end;
a pair of engaging arms extending backwardly from the front ends of the fixing portions, respectively, the pair of engaging arms being located between the fixing portions, each of the engaging arms having a front arm extending rearwardly from the front end of the fixing portion and away from the fixing portion, a rear arm connecting with the front arm and being bent toward the fixing portion and a contact portion formed at a boundary of the front arm and the rear arm; and
a pair of support members respectively stamped from the fixing portions and extending forwardly and inwardly towards the engaging arms, wherein each the support members is a cantilevered arm having an engaging portion at a distal end thereof, the engaging portion being disposed between the rear arm and the fixing portion in such a manner that the engaging portion is correspondingly aligned with the rear arm of the engaging arm in an inward-to-outward direction perpendicular to the fixing portion, and wherein the engaging portion is adapted for abutting against the rear arm.

5. The power contact as claimed in claim 4 , wherein the support member and the corresponding engaging arm from the same base portion extending essentially along two different directions, the two different directions intersecting with each other in an obtuse angle.

6. The power contact as claimed in claim 5 , wherein each fixing portion is wider than the engaging arm measured along the up-to-down direction, and wherein the engaging arm is also wider than the resilient arm along the up-to-down direction.

7. A power connector mated with a complementary plug, comprising:
an insulative housing comprising a front surface, a rear surface, a slot extending through the rear surface and a chamber extending through the front surface and the rear surface; and
a power contact comprising a fixing portion fixed in the slot, an engaging arm extending backwardly from a front end of the fixing portion and a support member stamped from the fixing portion, the engaging arm extending into the chamber mating with the complementary plug, the engaging arm having a front arm extending backwardly from the front end of the fixing portion and being obliquely away from the fixing portion, a rear arm connecting with the front arm and being bent toward the fixing portion and a contact portion formed at a boundary of the front arm and the rear arm, the contact portion contact with the complementary plug, the support member extending forwardly and inwardly towards the engaging arm, wherein the support member is a cantilevered arm having an engaging portion at a distal end thereof, the engaging portion being disposed between the rear arm and the fixing portion in such a manner that the engaging portion is correspondingly aligned with the rear arm of the engaging arm in an inward-to-outward direction perpendicular to the fixing portion; and
wherein when the complementary plug inserted into the chamber, the contact portion of the engaging arm is pressed by the complementary plug and the engaging portion of the support member is adapted to abut against the rear arm of the engaging arm.

8. The power connector as claimed in claim 7 , wherein the resilient arm and the engaging arm extending essentially along two different directions, the two different directions intersecting with each other in an obtuse angle.

9. The power connector as claimed in claim 7 , further comprising a soldering portion extending from the fixing portion along the first direction.

10. The power connector as claimed in claim 7 , wherein the power contact is of a symmetrical configuration with a base portion in a shape of sheet and defines an up-to-down direction, the fixing portion being a pair of the fixing portions bend perpendicularly from a pair of linear side of the base portion near an up end thereof, the engaging arm being a pair of the engaging arms extending backwardly from a front ends of the fixing portions, respectively, the support member being a pair of the support members stamped from the pair of fixing portions, respectively.

11. The power contact as claimed in claim 10 , further comprising a soldering portion extending downwardly from the base portion.

12. The power contact as claimed in claim 10 , wherein the fixing portion is wider than the engaging arm measured along the up-to-down direction and wherein the engaging arm is also wider than the resilient arm along the up-to-down direction.
