摘要： An electronic device enclosure includes a rear panel and a blocking board. The rear panel comprises a front surface and a back surface opposite to the front surface. A through opening is defined in the rear panel. The blocking board comprises a main body, a first flange and a second flange opposite to the first flange. A first stopping piece is extends from the first flange. A second stopping piece is extended from the second flange. A latch portion is located on the first flange. A first protrusion is located on the second flange. The latch portion and the second protrusion extend through the through opening by being elastically deformed, the latch portion and the second protrusion abut on the front surface, and the first stopping piece and the second stopping piece abut on the back surface.
