Patent ID: 8251728

Claim:
A card edge connector for connecting an electrical card to a printed circuit board comprising: an elongated housing defining a mating cavity extending along a longitudinal direction and a pair of arms disposed at opposite ends of the mating cavity, each arm having a locking arm and a stopping arm spaced from each other while commonly extending forward from the housing, a receiving space being defined between the pair of locking arms for receiving said electrical card while the stopping arm located at a lateral side of the locking arm beyond said receiving space; a plurality of contacts, divided into upper row contacts and lower row contacts, respectively secured on opposite sides of the mating cavity; a pair of retaining device, each comprising a base plate attached to the locking arm and a retaining portion extending toward the housing and secured in the housing; wherein a blocking portion extends outwardly from the base plate of the retaining device and stands at an exterior side of the stopping arm for preventing the locking arm from moving inwardly overly; wherein the blocking portion surrounds a bottom edge of the stopping arm; wherein a pair of supporting portions unitarily extend from opposite ends of the housing and located under the corresponding arms to support the card edge connector standing on said printed circuit board, and an interval is defined between corresponding stopping arm and the supporting portion for receiving said blocking portion; wherein a receiving slot is defined on a front face of the supporting portion and extends rearward for receiving a soldering pad therein; wherein each of said upper row contact and lower row contact respectively comprise a body portion and at least one retaining portion extending from the body portion, the upper row contact further comprises a contacting portion extending forward from an end of the body portion, while the lower row contact further comprises a contacting portion extending forward from an end of the at least one retaining portion; wherein the upper row contacts are inserted into housing from a rear side while the lower row contacts are inserted into the housing from a front side.
