Example

[0016] Reference will now be made to the drawings to describe the present invention in detail.

[0017] Referring to FIG. 1, an LGA connector 10 in accordance with a preferred embodiment of the present invention is provided for electrically connecting a CPU chip 80 to a PCB 90 (best seen in FIGS. 4 and 6). The LGA connector 10 may, of course, be applied in other environments such as for electrically interconnecting two PCBs and so on. The connector 10 comprises a rectangular insulative housing 30 and a plurality of terminals 50 received in the housing 30.

[0018] The housing 30 is configured with a bottom wall 32 and four side walls 34 extending upwardly from peripheries of the bottom wall 32. A receiving cavity 31 is defined between the bottom wall 32 and the side walls 34, for accommodating the CPU chip 3 therein. Guiding slant surfaces 340 are formed on the side walls 34 around a top mouth of the cavity 31, for facilitating insertion of the CPU package 90 into the cavity 31.

Abstract

A land grid array connector (10) for electrically connecting a CPU package to a printed circuit board includes a housing (30) having a top surface (320) and a number of terminals received in passageways (31) of the housing. Each of the terminals has a retention portion (52), a spring arm (54) extending from the retention portion beyond the top surface. A contacting portion (58) is formed on a topmost part of the spring arm for electrically mating with a corresponding pad formed on a bottom of the CPU package. A plurality of protrusions (324) is formed on the top surface for protect the terminals from being accidental damaged, A common supporting surface (326) is formed cooperatively by the protrusions, above the contacting portion in a direction perpendicular to the top surface. This can protect the contacting portion of the terminal from being collided. As a result reliable electrical connection between the package and contacts of the land grid array connector is secured.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the invention [0002] The present invention relates to electrical connectors, and more particularly to a land grid array (LGA) connector for electrically connecting an electronic package such as a CPU chip, to a circuit substrate such as a printed circuit board (PCB). [0003] 2. Description of the Prior Art [0004] Land grid array (LGA) electrical connectors are widely used in the connector industry for electrically connecting CPU chips to PCBs. A conventional LGA electrical connector is disclosed in U.S. Pat. No. 6,695,624. The electrical connector generally comprises an insulative housing and a plurality of electrical terminals received in the housing. Each terminal has a relatively long spring arm extending beyond outside the housing, for electrically mating with a corresponding pad on a CPU chip. However, the connector has a shortcoming that there is no protecting means for the terminals. When the connector is collided by an exterior o...
