Abstract

An electrical connector connecting with a chip module includes a base with a receiving space and a cover covering on the base. The cover includes a first edge, a second edge, a third edge and a fourth edge. The four edges connect with each other to form four engaging portions, and a rectangular opening surrounded therein. The first edge is pivotally connected to the base. The cover includes an extending portion extending from the second edge. The cover includes four pressing portions located at four inner corners of the cover.

First claim

What is claimed is:

1. An electrical connector connecting with a chip module, comprising:
base with a receiving space for bearing the chip module; and
a metallic cover covering on the base, the cover comprising a first edge, a second edge opposite to the first edge in a front-to-rear direction, a third edge and a fourth edge opposite to the third edge, the four edges connected with each other to form a rectangular opening, the first edge pivotally connected to the base, and an extending portion extending forwardly from the second edge;
wherein the metallic cover comprises at least four first pressing portions located at four inner corners of the cover to press the chip module;
wherein the first pressing portions are formed by stamping, and four concave spaces are formed at a top side of the cover;
wherein the four first pressing portions are disposed on four corners of the rectangular opening, and each of the pressing portions is of an L-shaped configuration;
wherein the base comprises an insulative housing, a plurality of terminals retained in the insulative housing and a metallic fixing member surrounded around the insulative housing, the fixing member with a mounting space comprises a first mounting portion and a second mounting portion opposite to the first mounting portion, four projections extend from the four inner corners of the mounting space, and the cover comprises four cutouts corresponding to the four projections; and
wherein the base comprises a first pivot member mounted on the first mounting portion, the cover is pivotally connected to the fixing member by the first pivot member, and the first mounting portion comprises two first standoffs protruding upwardly from the two opposite sides thereof.

2. The electrical connector as claimed in claim 1 , wherein two of first pressing portions located on the third edge connect with each other, and the other two first pressing portions located on the fourth edge connect with each other.

3. The electrical connector as claimed in claim 1 , wherein the cover comprises two second pressing portions located on the third edge and the fourth edge respectively, and each of the second pressing portions is located between two first pressing portions.

4. The electrical connector as claimed in claim 3 , wherein a center line is defined on the cover along a transverse direction perpendicular to the front-to-rear direction, and the center line passes through the two second pressing portions.

5. The electrical connector as claimed in claim 1 , wherein the first pivot member comprises a first locking portion and a first operating portion extending therefrom, and a gap is formed between the first locking portion and the first mounting portion because of the two lateral sides of the first locking portion standing on the two first standoffs.

6. An electrical connector comprising:
an insulative base forming a rectangular receiving space for snugly receiving a chip module therein; and
a metallic cover moveably positioned upon the insulative base in a pivotal manner, and having a rectangular configuration with opposite first and second sides and opposite third and fourth sides commonly define a rectangular opening, said first side and said second side parallel to each other, said third side and said fourth side parallel to each other, said first side and said second side perpendicular to said third side and said fourth side,
wherein at least four downwardly protruding pressing portions are located on four corners of said metallic cover and aligned with four corners of the rectangular receiving space for downwardly pressing in the receiving space;
wherein said four downwardly protruding pressing portions are formed by stamping with four concave spaces at a top side of the cover and directly formed from four corners of the rectangular opening;
wherein the electrical connector further including a metallic fixing member including four interconnected bars commonly in a horizontal plane to form an opening snugly surrounding the insulative base, wherein a pair of L-shaped levers pivotally mounted upon two opposite sides of the fixing member, the cover is pivotally mounted upon one of said levers, and a pair of standoffs are formed around two diagonally opposite corners of the fixing member outside of the corresponding two corners of the insulative base, respectively, for supporting the levers, respectively; and
wherein the metallic fixing member including four interconnected bars commonly in a horizontal plane to form an opening snugly surrounding the insulative base and forming a pair of elongated receiving slots along corresponding third and fourth sides of the insulative base, and the cover includes a pair of downwardly extending walls to be received within the pair of elongated receiving slots, respectively.

7. The electrical connector as claimed in claim 6 , wherein said metallic cover extends in a horizontal plane in a full flat manner except said at least downwardly protruding pressing portions.

8. The electrical connector as claimed in claim 6 , wherein said downwardly protruding pressing portions commonly define a rectangular peripheral boundary which is essentially aligned with a periphery of the rectangular receiving space in a vertical direction.

9. The electrical connector as claimed in claim 6 , wherein said four downwardly protruding pressing portions are discrete from one another without any interconnection between every adjacent two downwardly protruding pressing portions.

10. An electrical connector comprising:
an insulative base forming a rectangular receiving space for snugly receiving a chip module therein; and
a metallic cover moveably positioned upon the insulative base, and having a rectangular configuration with opposite first and second sides and opposite third and fourth sides commonly define a rectangular opening, said first side and said second side parallel to each other, said third side and said fourth side parallel to each other, said first side and said second side perpendicular to said third side and said fourth side, a pair of downwardly extending walls formed along the third side and the fourth side;
a metallic fixing member including four interconnected bars commonly in a horizontal plane to form an opening snugly surrounding the insulative base and forming a pair of elongated receiving slots beside the corresponding third and fourth sides of the insulative base to receive said pair of downwardly extending walls therein, respectively;
wherein the metallic cover is pivotal about the first side and at least a pair of downwardly protruding pressing portions are respectively formed at corners on the corresponding third and fourth sides of the metallic cover for downwardly pressing the chip module received in the receiving space;
wherein said at least two downwardly protruding pressing portions are formed by stamping having four concave spaces at a top side of the metallic cover and located within a boundary of the receiving space in a top view;
wherein a bottom end of each of said pair of downwardly extending walls is lower than a bottom end of each of the two downwardly protruding pressing portions;
wherein each of said pair of downwardly extend walls has a pair of cutouts at two opposite ends which are located within corresponding receiving slot.
