Abstract
A socket connector includes a metallic stiffener, an insulative housing, a load plate, a load lever and a plurality of washers. The stiffener defines a central opening in a middle portion thereof, the opening being surrounded by two pairs of inner surfaces. The housing defines a recessed conductive zone surrounded by sidewalls. The housing partially received in the opening of stiffener, and sidewalls interferentially engage with the inner surfaces in a direction parallel to the opening. The stiffener defines a plurality of through holes around the opening. Each of the through holes has two washers assembled therein from both sides of the stiffener; and every two washers assembled in a same through hole define a passageway in the middle thereof.

A socket connector for carrying an integrated circuit package, comprising:
- an insulative housing defining a recessed zone surrounded by two pairs of sidewalls;
- a plurality of conductive terminals received in the recessed zone;
- a metallic stiffener defining an upper side and a bottom side opposite to each other, and an opening surrounded by two pairs of inner surfaces, the opening surrounding the housing;
- a load plate and a load lever a pivotally assembled to the stiffener;
- the stiffener defining a plurality of through holes through both said upper and bottom sides and around the opening;
- wherein
- the connector further comprises a plurality of washers, each of the through holes having two washers assembled therein from both sides of the stiffener;
- wherein every two washers assembled in a common one of said through holes, define a passageway in the middle thereof;
- wherein each of the washers comprises a body portion having an upper surface and a lower surface opposite to upper surface, a passage defined between the upper surface and the lower surface;
- wherein the body portion of one of said two washers defines a snapped portion and the body of the other of said washers defines a slot into which said snapped portion is engaged;
- wherein
- the body portion of at least one of said two washers extends through said common through hole so as to have said snapped portion engaged within the slot for pre-assembling said two washers with each other and further to the stiffener under a condition that the stiffener is sandwiched between said two washers.
A socket connector, for electrically connecting an integrated circuit package to a circuit board, comprising:
- an insulative housing having a plurality of contacts receiving therein;
- a stiffener surrounding the housing;
- a load plate and a load lever pivotally assembled to the stiffener;
- wherein the stiffener defines a plurality of through holes, in assembly, a plurality of posts inserted into the through holes and holes of the circuit board for connecting the stiffener to the circuit board;
- wherein each of the through holes has two washers assembled therein and engageable with a post, so steady mechanical connection between the stiffener and the circuit board is possibly provided;
- wherein the two washers assembled therein and two washers are snapped together from both sides of the stiffener;
- wherein each of the washers defines a body portion having an upper surface and a lower surface opposite to upper surface, a passage defined between the upper surface and the lower surface;
- wherein
- the two washers are pre-assembled to each other and further to the stiffener before the post is engaged therewith under a condition that the stiffener is sandwiched between said two washers, and the post extends through the passages of both said washers during mounting the stiffener to the circuit board.
A socket connector assembly comprising:
- an insulative housing;
- a metallic stiffener surrounding the housing under a condition that no permanent securement between the stiffener and the housing;
- a plurality of first through holes defined in the stiffener;
- and
- a plurality of washer structures attached to the stiffener around the corresponding first through holes, respectively, each of said washer structures including upper and lower washer halves fastened to each other;
- wherein
- the upper washer half is located upon the stiffener while the lower washer half is located under the stiffener, under a condition that the stiffener is essentially tightly sandwiched between the upper washer half and the lower washer half so as to no relative vertical movement between the washer structure and the stiffener;
- wherein
- in each of said washer structures, at least one of said upper washer half and said lower washer half extends through the corresponding first through hole to the other of said upper washer half and said lower washer half for pre-assembling said upper washer and said lower washer half together and further having said washer structure fastened to the stiffener before said stiffener is mounted to a printed circuit board on which the housing is seated.
