Electrical connector with accurately secured contacts

A connector for electrically connecting an electronic package with a circuit substrate, the connector comprising:

• an insulative housing defining a plurality of passages therein;
• and
• a plurality of contacts secured in corresponding passages;
• wherein each of the contacts comprises a body portion, and the body portion comprises a first part adapted to be snugly received in a corresponding passage, and a tapered second part connecting with the first part for guiding the first part into the corresponding passage.

An electrical connector comprising:

• an insulative housing defining a plurality of passageways therein and communicating with a housing face thereon, each of said passageways including a main receiving portion and at least one fastening recess communicated with said main receiving portion;
• and
• a plurality of contacts respectively inserted into and retainably disposed in the corresponding passageways from the housing face, each of said contacts formed from sheet metal and including a main vertical body portion with a solder portion, a contact portion and an engaging portion directly or indirectly extending thereform, respectively, said engaging portion being received in the fastening recess;
• wherein
• a thickness of the engaging portion of the contact is slightly larger than a thickness of the recess so as to form an interference between the engaging portion and the corresponding recess in a direction perpendicular to a main plane of said engaging portion;
• wherein
• a tapered structure is formed on at least either in the recess adjacent to the housing face or on a distal end of the engaging portion which first approaches the recess during insertion of the contact into the corresponding passageway for facilitating insertion of the engaging portion into the recess while still keeping sufficient interference between said engaging portion and said recess when the contact is completely inserted into the passageway.
