Bracket having a recoverable door

A bracket for receiving an external electrical device, the bracket comprising:

• a dielectric frame;
• a door rotatably positioned on the dielectric frame by a shaft traversing the door, the shaft terminating as a cam portion at each distal end thereof;
• and
• a metal shielding fixingly attached to the dielectric frame and comprising spring arms proximate to the cam portion of the door;
• wherein the cam portion of the door is rotated to deform the spring arm of the metal shielding when the external electric device is inserted into the bracket from the door, the door being normally biased closed by the spring arms;
• wherein the dielectric frame has a bottom and two side walls extending upright from two sides of the bottom;
• wherein each side wall of the dielectric frame has a top surface and an opposite bottom surface and a post extends downwardly from the bottom surface of the side wall;
• wherein a beam is connected between front ends of the side walls thus forming a gate for entrance of the external electrical device;
• wherein a pair of positioning recesses are defined in opposite positions defined in the side walls of the dielectric frame for positioning the door;
• wherein each of the positioning recesses is a cutout formed at a top surface of the side wall.
