Abstract
An LGA connector, for interconnecting an IC package with a printed circuit board, includes an insulative housing having a number of electrical terminals received therein, a metal stiffener mounted to the insulative housing, a cover and a lever pivotally engaged to two opposite ends of the stiffener, respectively. The insulative housing defines an opening for receiving the IC package and two walls extending upwardly thereof, and each wall disposes a first cutout. The stiffener surrounding the insulative housing defines two side walls adjacent and parallel to the walls of the insulative housing. Each side wall disposes a second cutout corresponding to the first cutout so as to so as to remove the IC package easily.
Claims16
A land grid array connector for interconnecting an electronic package and a circuit substrate, comprising:
- an insulative housing receiving a plurality of terminals, including a base portion and two opposite peripheral walls extending upwardly from the base portion, and each wall defining a first cutout for removing the electronic package easily;
- a stiffener surrounding the insulative housing and comprising a bottom plate, two sidewalls extending upwardly from the bottom plate and adjacent to the walls of the insulative housing and two opposite ends extending between said two sidewalls, and each sidewall defining a second cutout corresponding to the first cutout of the insulative housing;
- and
- a cover pivotally mounted to one of said opposite ends of the stiffener.
A fastening device, for fixing an electronic package to an electrical connector, comprising:
- a stiffener comprising a bottom plate, two longitudinal sidewalls extending upwardly from the bottom plate and two ends extending between said two longitudinal sidewalls, each longitudinal sidewall defining a cutout in center thereof and running through a top edge of the sidewalls;
- a cover pivotally mounted to one end of the stiffener;
- and
- a lever pivotally mounted to the other end of the stiffener;
- wherein
- the lever includes a pivotal arm and an operational arm extending perpendicularly from one end of the pivotal arm;
- wherein
- a handle extends upwardly and forwardly from a distal end of the operational arm, and the handle and the operational arm are located in a vertical plane paralleled to one of the sidewalls.
An electrical connector comprising:
- a rectangular metallic stiffener defining a bottom plate with a rectangular configuration having thereof two longitudinal sides extending along a longitudinal direction and two transverse ends extending along a transverse direction perpendicular to said longitudinal direction, said stiffener including two opposite side plates extending upwardly from two opposite edges of the two longitudinal sides of the bottom plate;
- a hook unitarily formed on one of said side plate;
- an insulative housing located between said opposite side plates in said transverse direction for receiving an electronic package;
- a load plate pivotally mounted to one end of the stiffener;
- and
- a lever pivotally mounted to an opposite end of the stiffener to lock the load plate in position, and defining an operation arm moveable in a vertical plane closer to one of said opposite side plates;
- wherein
- said one of said opposite side plates defines a downward cutout located around said hook and configured to be long enough in said longitudinal direction to allow a finger to enter in said transverse direction for not only easy operation of said operation arm but also less interference between the load plate and the stiffener.
