Electrical coupler
A coupler for connection to a substrate for mounting electronic devices. The coupler includes a coupling contact formed from metal and having opposing planar surfaces. The coupling contact includes a body having a pair of arms and a pair of legs joined thereto. The coupling contact is pivotally mounted to a frame formed from metal. The frame includes a body having a center plate with front and rear appendages joined thereto. The center plate has a top edge about which the coupling contact may pivot. The frame further includes a pair of holders having holding slots formed therein, respectively. The holders are disposed on opposing sides of the center plate, respectively, whereby portions of the arms are disposed in the holding slots, respectively.

3 . The coupler of claim 2 , wherein the frame is monolithic.
4 . The coupler of claim 1 , wherein the frame further includes a plurality of feet joined to a bottom portion of the center plate, the feet extending laterally outward from the center plate.
5 . The coupler of claim 4 , wherein the feet are disposed at about right angles to the center plate.
6 . The coupler of claim 5 , wherein a first one of the feet is disposed on a first side of the center plate and a second one of the feet is disposed on a second side of the center plate, whereby the first and second feet extend in opposite directions.
7 . The coupler of claim 1 , wherein the front and rear appendages are each generally C-shaped and each comprise an end panel joined by bends between side panels.
8 . The coupler of claim 7 , wherein the front appendage opens rearwardly and the rear appendage opens forwardly.
9 . The coupler of claim 7 , wherein the body of the frame is generally S-shaped.
10 . The coupler of claim 7 , wherein the coupler is configured to be mounted in an opening in the substrate.
11 . The coupler of claim 10 , wherein a first flange tongue is joined to a top edge of the end panel of the front appendage and extends forwardly therefrom, and a second flange tongue is joined to a top edge of the end panel of the rear appendage and extends rearwardly therefrom.
12 . The coupler of claim 11 , wherein a third flange tongue is joined to a top edge of an outer one of the side panels of the front appendage and extends laterally outward therefrom, and a fourth flange tongue is joined to a top edge of an outer one of the side panels of the rear appendage and extends laterally outward therefrom.
13 . The coupler of claim 7 , wherein the tangs are joined to outer panels of the side panels of the front and rear appendages, respectively.
