Abstract

An electrical connector (1) for connecting a land grid array (LGA) chip (2) with a printed circuit board includes an insulative housing (12), a frame (11) engaged with the housing, and a plurality of terminals (13) received in the housing. The housing defines two adjacent sides (122, 123). A plurality of arcuate protrusions (1220, 1230) is formed on said sides. The frame has four sidewalls (110, 113, 114, 115) defining a central cavity (111) therebetween for receiving the LGA chip therein. Two adjacent of the sidewalls define a plurality of cutouts (1110, 1130) in respective inner faces thereof, corresponding to the protrusions respectively. The frame is mounted on the housing, with the protrusions being engagingly received in the corresponding cutouts. When the LGA chip is engaged with the connector, the protrusions elastically deform to accurately guide and securely fix the LGA chip in the connector.

Claims

1. An electrical connector for connecting an electronic package with a circuit substrate, the electrical connector comprising:

an insulative housing defining a space thereabove for receiving the electronic package;

a rectangular frame engaged with the housing and mounted on the circuit substrate, the frame comprising four sidewalls, at least two of the sidewalls each defining a cutout in inner faces of the frame;

wherein

the housing defines a plurality of edge, at least two of the edges each having a protrusion thereat, the protrusion being received in the cutout; and

the cutout enlarges the periphery of the space, whereby the protrusion elastically deform to contact and engage the electronic package in the electrical connector.

2. The electrical connector as claimed in claim 1, wherein a cross-section of each of the protrusion is arcuate.

3. The electrical connector as claimed in claim 1, wherein upper portions of the protrusion are beveled, with bevels facing generally toward a middle of the housing.

4. The electrical connector as claimed in claim 1, wherein two latches are provided on two diagonally opposite corners of the housing.

5. An electrical connector assembly, comprising:

an insulative housing defining a space thereabove for receiving the electronic package; and

a rectangular frame mounted to the housing and the frame having four raised sidewalls, at least two of the sidewalls together defining a plurality of cutouts in respective inner faces thereof;

wherein the housing further defines at least two edges having a plurality of protrusions arranged thereat, the protrusions being engagingly received in the cutouts of the frame and partially protruding beyond the inner faces into the space.

6. The electrical connector assembly as claimed in claim 5, wherein a cross-section of each of the protrusions is arcuate.

7. The electrical connector assembly as claimed in claim 5, wherein upper portions of the protrusions are beveled, with bevels facing generally toward a middle of the housing.

8. An electrical connector assembly comprising;

a housing defining a mating face thereon and a plurality of resiliently deformable protrusions at two edges thereof;

a frame fixed to the housing and being substantially rectangular and including four raised sidewalls, a plurality of cutouts defined in inner faces of two of the sidewalls and receiving the protrusions therein; and

an electronic component located above the mating face of the housing;

wherein

the protrusions of the housing physically contact and position the electronic component between the sidewalls of the frame.

9. The electrical connector assembly as claimed in claim 8, wherein a cross-section of each of the protrusions is arcuate.

10. The electrical connector assembly as claimed in claim 8, wherein upper portions of the protrusions are beveled, with bevels facing generally toward a middle of the housing.
