Electrical connector with low profile contacts

An electrical connector comprising:

• an insulating housing having a plurality of passageways;
• a plurality of contacts retained in said passageways of the insulating housing, said contact having a retaining beam engaged with the insulating housing, a first contacting beam extending from said retaining beam, a second contacting beam opposite to said first contacting beam and a connecting portion connected with said first and second contacting beam;
• wherein said second contacting beam and said connecting portion define an acute angle between 10° to 40° the insulating housing has a blocking portion protruding into the passageway to downwardly block the second contacting beam from upwardly moving, wherein said blocking portion defines a concave room located under the blocking portion and running through the passageways, wherein said first contacting beam and said connecting portion define an acute angle between 30° to 60°, wherein the second contacting beam has a lower arc portion connecting with said connecting portion, said lower arc portion further extends into the concave room and is upwardly blocked by the blocking portion.
