Ball grid array socket

A socket contact being mountable on a substrate and matable with a ball contact comprising:

• contact retention points disposed on resilient arms extending substantially perpendicular to a bottom wall, the contact retention points extend into an opening defined by the resilient arms, the resilient arms being configured to allow for the elastic deflection thereof as a mating ball contact is brought into engagement with the socket contact, such that when the mating ball contact is fully inserted, the resilient arms will return toward an unstressed position to cooperate with the periphery of the mating ball contact to maintain the mating ball contact in position.

A substrate mating assembly comprising:

• a first substrate with at least one mating contact mounted thereon, the at least one mating contact having an arcuate surface and dimensioned to be received in a contact receiving opening of at least one socket contact,
• a second substrate with the at least one socket contact mounted thereon, the at least one socket contact having contact retention points disposed on resilient arms extending into a contact receiving opening thereof, the resilient arms are configured to allow for the elastic deflection thereof as the at least one mating contact is brought into engagement with the at least one socket contact, such that when the at least one mating contact is fully inserted, the resilient arms will return toward an unstressed position to cooperate with the arcuate surface of the at least one mating contact.

A socket assembly for establishing an electrical connection to a ball contact comprising:

• a socket being mountable on a substrate at a bottom wall and having contact retention points disposed on resilient arms extending from the bottom wall, the contact retention points extend into an opening defined by the resilient arms, the resilient arms being configured to allow for the elastic distortion thereof as a mating ball contact is brought into engagement with socket, such that when the mating ball contact is fully inserted, the resilient arms will return toward an unstressed position to cooperate with the periphery of the mating ball contact to maintain the mating ball contact in position.
