Electronic device and securing structure for fixing printed circuit board

A securing structure for a printed circuit board, comprising:

• a housing configured to form a cavity and having an opening, the housing having a first interior surface opposite the opening;
• a flange extending inward into the cavity from the first interior surface, the flange having an outer end furthest from the interior surface;
• and
• at least one support block, each support block comprising:
• a first rib;
• a second rib, the second rib opposite to and substantially parallel to the first rib;
• a connector element positioned between, and substantially perpendicular to, the first rib and the second rib;
• wherein, the at least one support block is attached to the outer end of the flange with the first rib and second rib substantially parallel to the flange;
• and
• wherein, a printed circuit board with at least one notch is receivable in the housing so that the connector element of the at least one support block is insertable within the notch allowing the first rib and the second rib support the printed circuit board.

An electronic device receiving a printed circuit board, the electronic device comprising:

• a housing;
• a cover detachably covered on one end of the housing;
• and
• at least two securing structure, one of the at least two securing structures located inside the housing and adjacent to the other end of the housing opposite to the cover, another one of the securing structures located inside the cover, the securing structure comprising:
• a flange;
• a first rib attached to the flange;
• a second rib, the second rib opposite to and substantially parallel to the first rib;
• and
• a connector element positioned between, and substantially perpendicular to, the first rib and the second rib;
• wherein the printed circuit board is located between the first rib and the second rib, and the block is locked the printed circuit board.
