Locking device for locking an edge card to an electrical connector

A locking device for securing an edge card to an electrical connector in which the edge card has a lower edge to be inserted into the electrical connector to electrically connect therewith, the locking device comprising:

• a first locking portion having an elongated locking body and two clips extending from opposite ends of the locking body, wherein each clip includes two resilient arms formed at a distal end thereof;
• a pair of second locking portions formed on two opposite ends of the electrical connector;
• wherein the resilient arms of the first locking portion are resiliently inserted into the second locking portions to make a secure connection therein, and upper and side edges of the edge card can securely engage the first locking portion, thereby securing the edge card to the electrical connector;
• wherein a connecting portion is formed between the locking body and each clip and includes two parallel ribs forming a receiving space therebetween for receiving two upper corners of the edge card;
• wherein each clip defines a slot extending from a free end to a middle portion of the clip thereby separating a lower portion of the clip into the two resilient arms;
• wherein each clip of the first locking portion forms two oppositely directed barbs on the free ends of the arms and the second locking portions each include a pair of holes on each of opposite faces of the electrical connector corresponding to the barbs of the first locking portion for securing the barbs;
• wherein each clip further has two oppositely directed pressing portions at the middle portion thereof for being pressed together to actuate the resilient arms to move inwardly.
