Abstract

A preferred embodiment of a connector system includes a first electrical connector for mounting on a first substrate. The first electrical connector has a housing, and a contact mounted on the housing. The connector system also includes a second electrical connector for mounting on a second substrate. The second electrical connector includes a housing having a projection formed thereon, and a contact mounted on the housing. The second electrical connector is capable of mating with the first electrical connector so that the contact of the first electrical connector electrically contacts the contact of the second electrical connector and the projection contacts the first substrate so that at least a portion of the weight of the second electrical connector and the second substrate is transmitted to the first substrate by way of the projection.
