Abstract

An electrical connector includes a lengthwise housing and two rows of terminals. The housing defines two rows of passageways running through opposite first surface and second surface thereof to load with terminals. Each terminal includes a middle portion and two contacting arms extending from opposite ends of the middle portion. The two contacting arms of the terminals respectively extend beyond the first and second surfaces and curving inwards. Each terminal further includes a stopping rib and a spring rib at opposite lateral sides of the middle portion. Each passageway defines a first stopping shoulder adjacent to the second surface and a second stopping shoulder adjacent to the first surface. The stopping ribs are lodged against the first stopping shoulder or the spring ribs are lodged against the second stopping shoulder so that the terminals are moveable limited in the passageways.

Claims

1. An electrical connector adapted for connecting with two circuit boards, comprising:

a lengthwise insulating housing defining a first surface and a second surface opposite to the first surface confronting with said two circuit boards respectively, the insulating housing comprising two rows of passageways arranged along a lengthwise direction thereof and running through the first surface and the second surface; and

two rows of conductive terminals respectively disposed in the two rows of passageways, each terminal comprising a middle portion and two contacting arms extending from opposite ends of the middle portion for elastically pressing against said two circuit boards, the two contacting arms of said terminals respectively extending beyond the first and second surfaces and curving inwards;

each terminals further comprising a stopping rib at a first lateral side of the middle portion and a spring rib at a second lateral side opposite to the first lateral side of the middle portion, each passageway defines a first stopping shoulder adjacent to the second surface and a second stopping shoulder adjacent to the first surface;

wherein the stopping ribs are lodged against the first stopping shoulder or the spring ribs are lodged against the second stopping shoulder so that the terminals are moveable limited in the passageways in a condition that a distance between the first stopping shoulder and the second stopping shoulder is larger than that between the stopping rib and the spring rib along a height direction perpendicular to the first and second surface.

2. The electrical connector as described in claim 1, wherein the stopping rib is in a same planar of the middle portion and each spring rib defines a first spring arm and a second spring arm at opposite ends thereof extending slantwise in opposite directions to offset the planar of the middle portion, the first spring arm are lodged against the second stopping shoulder.

3. The electrical connector as described in claim 2, wherein each passageway comprises a first portion and a second portion orthogonally to the first portion, the first stopping portion and the second stopping shoulder are located in the second portion and at opposite sides of the first portion of the passageway.

4. The electrical connector as described in claim 3, wherein the first spring arms bend with a larger angle than the second spring arms.

5. The electrical connector as described in claim 4, wherein the passageway defines a third stopping shoulder adjacent to the second surface at an opposite side of the second stopping shoulder against which the second spring arm is lodged.

6. The electrical connector as described in claim 5, wherein the terminals of said two rows are aligned with each other one by one in a transverse direction perpendicularly to the lengthwise direction and the height direction, the contacting arms are perpendicular to the planar of the middle portion.

7. An electrical connector adapted for connecting with two circuit boards, comprising:

a housing defining a first surface and a second surface opposite to the first surface confronting with said two circuit boards respectively, the housing comprising passageways running through the first surface and the second surface; and

two parallel rows of terminals respectively disposed in the passageways, each terminal comprising a middle portion and two contacting arms extending from opposite ends of the middle portion for elastically pressing against said two circuit boards, the two contacting arms of said terminals respectively extending beyond the first and second surfaces and curving inwards;

the middle portions of the terminals being received in the passageways and shifting in the passageways along a second direction from the first surface to the second surface;

each terminals further comprising a stopping rib and a spring rib at opposite lateral sides of the middle portion, each passageway defines a first stopping shoulder adjacent to the second surface and a second stopping shoulder adjacent to the first surface;

wherein the stopping ribs are lodged against the first stopping shoulder when the terminals move towards the second surface and the spring ribs are lodged against the second stopping shoulder when the terminals move towards the first surface.

8. An electrical connector comprising:

an insulative housing defining a plurality of passageways extending therethrough along a vertical direction between opposite upper and bottom surfaces thereof;

a plurality of contacts disposed in the corresponding passageways, respectively, each of said contacts defining a main body spanning in a lengthwise direction of the housing with resilient contacting arms extending therefrom oppositely in said vertical direction and beyond the corresponding upper and bottom surfaces; and

a pair of opposite spring arms extending oppositely in said vertical direction from one side of the main body of each of the contacts under condition that the pair of spring arms also extend in opposite lateral directions perpendicular to said vertical direction and said lengthwise direction.

9. The electrical connector as claimed in claim 8, wherein a guiding rib is formed on the other side of the main body opposite to the pair of spring arms in the lengthwise direction.

10. The electrical connector as claimed in claim 9, wherein said guiding rib extends coplanar with the main body.

11. The electrical connector as claimed in claim 8, wherein the housing defines a pair of corresponding stepped structures in each of the passageways in the vertical direction, against which the corresponding spring arms abut, respectively.

12. The electrical connector as claimed in claim 11, wherein each of said passageways defines an L-shaped opening in the one of the upper and bottom surfaces, and a T-shaped opening in the other of the upper and bottom surface.

13. The electrical connector as claimed in claim 11, wherein each of the contacts is floatable between the corresponding pair of stepped shoulder.
