Abstract
A plurality of contact are received within the corresponding passageways of the insulative housing of an electrical connector, respectively. Each contact has juxtaposed first body and second body angled with each other via a connecting section linked therebetween. A resilient contacting section extends upwardly from the first body. The bottom portion of the second body forms sideward spaced first blade and second blade with a slit therebetween, wherein a soldering tail further extends from the first blade, and the second blade is sideward farther from the first body than the first blade is. The bottom edge of the first body is lower than the bottom edge of the connecting sections o as to form another slit between the first body and the second body under the connection section.
Claims11
An electrical connector for electrically connecting an electronic package to a printed circuit board, comprising:
- an insulative housing forming a plurality of passageways to securely receive a plurality of corresponding contacts, a plurality of solder balls being attached to the corresponding contacts, respectively;
- a stiffener surrounding the housing a load plate pivotally mounted to one end of the stiffener for holding the electronic package in the housing, and a lever pivotally mounted to the other end of the stiffener for securing the load plate in position;
- each of said contacts formed by sheet metal and including:
- a first body and a second body sideward spaced from and angled with each other and linked to each other via a connecting section;
- a spring arm extending upwardly from an upper portion of the first body;
- a first blade and a second blade extending downwardly from a lower portion of the second body and sideward spaced from each other with a slit therebetween;
- and
- a horizontal soldering tail linked at a bottom end of the first blade;
- wherein
- the second body forms a barbed structure on a lateral outer edge for retaining the contact in the corresponding passageway, and said barbed structure is higher than the first blade and the second blade in the vertical direction;
- wherein
- the connecting section is higher than the first blade and the second blade in the vertical direction;
- wherein
- a width of the slit is around 0.10 mm˜0.25 mm and a length of the slit is around 0.25 mm˜0.40 mm.
