Abstract: An electrical connector includes at least a pair of metal latches embedded in two opposite end portions of the connector, each latch having a pair of snapping leg members engageably locked in a recess portion recessed in each end portion of the connector and two latches insertably fixed on two opposite end portion of the connector for clamping a daughter printed circuit board on the connector so that the daughter board will be electrically connected with a mother printed circuit board secured under the connector.

Abstract: An electrical connector includes a plurality of contact elements each contact element formed with two spring arm members and two contacting protrusions disposed in a slot formed in a connector base for homogeneously exerting multiple elastic forces on the contact element for firmly clamping a daughter printed circuit board thereon in order to efficiently clamp the daughter board to a mother printed circuit board connected with the electrical connector. The electrical connector also includes a pair of metal latches respectively embedded on two opposite end portions of a connector base of the electrical connector for resiliently holding the daughter board for prolonging a service life of the latches of the connector.

Abstract: An electrical connector includes a contact element formed with a main spring arm member protruding inwardly from a side engaging member of the contact element embedded in a slot formed in a connector base of the electrical conenctor defining a bow portion between the main spring arm member and the side engaging member for forming an essential elastic force by the bow portion for enhancing a resilient clamping effect for efficiently clamping a daughter printed circuit board by two contacting protrusions of the contact element.
