Abstract: An LGA connector contact (30) includes a base (31), and a pair of spring arms (32) extending from the base. Each of the spring arms includes an extending section (320), a connecting section (321), and a contacting section (322) adapted for engaging a circuit board's contact pad. The contacting section has an exterior side and an interior side with a recess (323) on the exterior side of the contacting section around a middle portion of the contacting section so as to define at least a pair of contact regions (324) adjacent the recess. The LGA contacting portion is configured to have its contact regions electrically engage with an un-oxidized portion of the circuit board's contact pad, thereby achieving an effective electrical connection between the LGA connector contact and the corresponding circuit board pad.

Abstract: A contact module with connectors adapted to engage with first and second electrical conductors such that when resiliently interfaced with the conductors there is a net zero moment of inertia exerted on the conductors. Each individual connector exerts a resilient spring force to engage with an electrical conductor. When such resilient forces, as in the prior art are aggregated, they can exert a considerable vectored moment of inertia on the electrical conductors to which they are connected. The connectors of the present invention are arranged so that each individual connector has an opposing connector somewhere in the module to offset each individual moment of inertia so that the net sum of all moments on the interfacing electrical conductor is zero.

Abstract: Provided is an electrical connector (3) including an insulative housing (20) defining a number of passageways (202) and a number of contacts (1) received in the corresponding passageways, respectively. Each passageway defines a T-shaped cross-sectional configuration including a narrow fastening slot (2021) and a wide receiving slot (2022) communicated with each other.
