Socket with improved load plate
A socket for electrically connecting an IC package to a printed circuit board, comprises an insulative housing, a stiffener surrounding the housing and having a front wall defining a hole; and a load plate pivotably mounted to the front wall of the stiffener. The load plate has a pivotal portion with a hook, the hook has a latching finger engaging with the latching hole of the stiffener, a protruding finger and a gap defined between the latching finger and the protruding finger. The protruding finger resists the stiffener when the load plate deflects on a top-to-bottom direction relative to the stiffener. The protruding finger also can engage with the stiffener to guide the load plate to rotate in a correct direction.
1. A socket for electrically connecting an IC package to a printed circuit board, comprising:
an insulative housing; a metallic stiffener surrounding the insulative housing and having a front wall defining a latching hole; and
a metallic load plate pivotably mounted on a top wall of the insulative housing and to the front wall of the stiffener and rotating relative to the stiffener, the load plate provided with a hook which has a latching finger latching with the latching hole of the stiffener and a protruding finger extending forwardly, the protruding finger disposed lower than the latching finger and resisting the stiffener when the load plate deflects in a horizontal direction during a downward rotation of the load plate;
wherein a gap is defined between the latching finger and the protruding finger, the protruding finger is disposed on an outside of the gap;
wherein the protruding finger of the load plate is lower than the latching finger, so the protruding finger can resist the stiffener to prevent the load plate from further deflection;
wherein the stiffener comprises a bottom wall, the front wall and a rear wall oppositely extending upwardly from the bottom wall, respectively;
wherein the front wall of the stiffener is formed with a top edge and a linking rib connecting the top edge with the bottom wall, the gap of the load plate receives the linking rib; and
wherein there are two spaced hooks, the load plate has a tail between the spaced hooks.
2. The socket as claimed in claim 1 , further comprising a lever pivotally assembled to the rear wall of the stiffener.
3. A socket for electrically connecting an IC package to a printed circuit board, comprising:
an insulative housing;
a metallic stiffener surrounding the insulative housing and having a front wall which having a latching hole and a top edge above the hole and a linking rib connecting to top edge and disposed on an outside of the latching hole, and
a metallic load plate pivotably mounted to the front wall of the stiffener, the load plate having a hook, which has a protruding finger and a latching finger, the latching finger inserting into the latching hole of the stiffener and rotating around the top edge, a gap defined between the latching finger and the protruding finger to receive the linking rib of the stiffener;
wherein the protruding finger engages with the linking rib to guide the load plate to rotate in a correct direction;
wherein the protruding finger of the load plate is lower than the latching finger, and resists the stiffener when the load plate deflects on a top-to-bottom direction relative to the stiffener;
wherein there are two spaced hooks, and the load plate has a tail between the spaced hooks;
wherein the stiffener comprises a bottom wall, the front wall and a rear wall oppositely extending upwardly from the bottom wall, respectively; and
wherein the front wall of the stiffener is formed with a top edge and a linking rib connecting the top edge with the bottom wall, the gap of the load plate receives the linking rib.
