摘要： An electrical connector for electrically connecting a module to a printed circuit board, comprises an insulative housing receiving the module, a plurality of contacts received in the insulative housing and a cover pivotally assembled to the insulative housing. The cover presses upon the module and extends beyond a rear end of the insulative housing to further limit or press a part of the module exposed outside the insulative housing. The electrical connector can reliably retain the module.

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： 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.

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： An electrical socket for interconnecting an LGA chip with a PCB includes an insulative housing (2) and a multiplicity of terminals (1). The housing includes a plurality of passageways (26) extending therethrough for engagingly accommodating corresponding terminals. Each terminal includes a locating plate (10) arranged in rows, and a mating beam (12) connected to the locating plate and extending along the corresponding row. The terminals and the mating beams are arranged so that a projection A of each mating beam along the corresponding row is longer than a distance B between each two adjacent locating plates of two adjacent terminals arranged in the same row. Accordingly, when the mating beams are engaged with electrodes of the LGA chip, the mating beams are long enough to provide excellent resilient deflection characteristics, thereby ensuring good mechanical and electrical connection between the mating beams and the electrodes.
