Electrical connector for an electronic package

Claim 1

An electrical connector for mounting a planar leadless electronic component package on a substrate, comprising a housing of electrically insulating material carrying a plurality of electrical contacts providing first contact points for engagement with conductors on the package and second contact points for engagement with conductors on the substrate, and a lid which when connected to the housing in a closed condition serves to urge a package mounted on the housing, into contact with the first contact points of the contacts, and to secure the package to the connector, characterised in that the housing is formed at its periphery with a plurality of holes each to receive a bolt by which the connector is to be secured to the substrate, the lid being in the form of a spring member having a plurality of forked portions engageable under the heads of respective bolts when securing the connector to the substrate and having hold-down portions resilient relative to the forked portions and arranged to engage the package and hold the package on the housing said lid being comprised of an inner planar frame formed by side strips which in use serve as package hold-down portions, each side strip carrying outside the frame a pair of oppositely extending arms which extend parallel to the side strip and upwardly relative to the plane of the frame, adjacent free end portions of the arms together constituting the forked portions engageable under the heads of the bolts.
