摘要： A land grid array connector (1) for electrically connecting a CPU package (3) to a printed circuit board includes a housing (2) and a number of contacts received in passageways (284) of the housing. The housing has a bottom wall (28) and sidewalls (22,24,26). The bottom wall and the sidewalls cooperatively define a receiving space (20) for accommodating the package therein. Protrusion member (228) is formed on the sidewalls and extends inwardly into the receiving space. A through hole (280) below the protrusion member is defined in the bottom wall for facilitating molding the protrusion member. The protrusion member is configured with a vertical abutting surface (2280) formed at a lateral end toward the receiving space thereof. The bottom wall forms a mounting surface (2820) for sustaining the CPU chip thereon. A vertical shortest distance is formed between a lowest end of the abutting surface of the protrusion member and the mounting surface of the bottom wall. This configuration can protect the sidewalls of the housing from being scraped during insertion of the package into the housing. Reliable electrical connection between the package and contacts of the land grid array connector is secured.

摘要： The electrical connector has an insulative housing and a number of contacts embedded in the housing and distributed in rows and columns. Each of the contact has a pair of contacting arms with a contacting portion thereon for electrically connecting with a pad of the electronic package. The contacting portions of the contacts are arranged in a pattern of contact portions of two adjacent contacts in same row can engage with a same pad on the electronic package when the electrical connector is coupled with the electronic package, such that the contacts of the row are coupled with each other in series. By way above mentioned, pitch between two adjacent contacts can be reduced and a high density of the contacts can be achieved.

摘要： An electrical connector for electrically connecting an integrated circuit package to a circuit substrate includes a first and a second unit sections, and each unit section has a number of terminals received therein. Each unit section includes a mating surface, an opposed mounting surface, a fixing edge, and an engaging edge. The engaging edge of the first unit section has a protruding tongue, and the engaging edge of the second unit section defines a recessed portion for engaging the protruding tongue. An interlocking device is formed between the protruding tongue and the recessed portion, so that the protruding tongue is capable of overlapping and combined with the recessed portion via the interlocking device to make the first and the second unit sections become a unitary structure.

摘要： Disclosed is an electrical connector assembly including an insulative housing (10) with a plurality of passageways (103) therethrough from a top mating interface (100). A plurality of terminals (20) is inserted into the passageways with upper connecting portions (202) thereof have projections overlapped. A floating cover (30) is movably mounted above the base, and defines at least one slot (305) extending in a row direction along which, from a top view, the whole upper connecting portions direct to. The slot is configured to allow for upper mating sections (2021) of the whole row of terminals to be simultaneously extended therethrough when the floating cover is pressed downwardly to engage with the base. Thus, no damage will bring to the terminals that have overlapped configuration.
