An electrical connector for mating with a male contact of a mating connector is capable of exerting a selectively variable contact force. The electrical connector includes a conducing member having a lead and a contact beam electrically coupled to the lead. The contact beam is adapted to resiliently engage the male contact. The electrical connector further comprises a contact housing. At least a portion of the lead is disposed within the contact housing. At least a portion of the contact beam is disposed within the contact housing so that the contact beam is urged into and restrained by the contact housing when the contact beam resiliently engages the male contact. A contact force is thereby generated between the contact beam and the contact pin. The contact housing is capable of being selectively positioned in relation to the contact beam so that a point of restraint on the contact beam is selectively variable. The contact force between the contact beam and the male contact can thereby be varied on a selective basis.

Electrical socket for substrates

An electrical socket for substrates and particularly ceramic substrates. More particularly, the socket includes a U-shaped receptacle and a mounting section for attaching the receptacle to the substrate. The mounting section is attached to one leg of the receptacle and includes a solder foot for being soldered to a circuit pad on the substrate.

Electrical connector with grounding system

An electrical connector (10) comprising a housing (12) and electrical contacts (32, 34) connected to the housing (12). The electrical contacts (32, 34) comprise paired signal and ground contacts, and additional ground contacts (34a). The additional ground contacts (34a) are arranged relative to the paired contacts to divide the paired contacts into subdivisions of equal numbers of the paired contacts. The subdivisions and the additional ground contacts (34a) are arranged to allow for multiple relative orientation connections of a mating connector (100).

Printed circuit board stiffener assembly

A stiffener assembly for mechanically supporting the main body of an electrical connector to a circuit substrate, such as a daughterboard Printed Circuit Board (PCB). The PCB stiffener assembly is utilized to minimize bowing in the PC Board. The stiffener assembly includes a two-piece or split body having a top clamp and a bottom channel. A latch formed on the top clamp fits over and connectively engages a retention structure disposed on a rear surface of the connector housing. A bottom portion of the top clamp is disposed with in the bottom channel. The bottom channel rests on the PCB and the legs of the bottom channel extend upward form the surface of the PCB. One leg of the bottom channel rest against the rear panel and fits under the retention structure. Fasteners pass through the PCB and the bottom channel and engage the top clamp thereby retaining the connector on the PCB. The stiffener assembly simultaneously aligns one or more connector modules to one another creating a one piece "mo no- block" like effect while at the same time acting to stiffen the PCB thereby reducing any PCB bowing. The two-piece stiffener assembly allows for individual connector modules to be removed from the PCB by simply removing the top clamp portion of the PCB stiffener assembly. The stiffener provides a mechanism for mechanically supporting the main body of a connecto r module to a daughterboard PCB in a manner that is easy to manufacture and cost effectiv e.

Electrical connector capable of exerting a selectively variable contact force

An electrical connector (11) for mating with a male contact of a mating connector is capable of exerting a selectively variable contact force. The electrical connector (11) includes a conducting member (20) having a lead (26) and a contact beam (24a, 24b) electrically coupled to the lead (26). The contact beam (24a, 24b) is adapted to resiliently engage the male contact. The electrical connector (11) further comprises a contact housing (15). At least a portion of the lead (26) is disposed within the contact housing (15). At least a portion of the contact beam (24a, 24b) is disposed within the contact housing (15) so that the contact beam (24a, 24b) is urged into and restrained by the contact housing (15) when the contact beam (24a, 24b) resiliently engages the male contact. A contact force is thereby generated between the contact beam (24a, 24b) and the contact pin (28). The contact housing (15) is capable of being selectively positioned in relation to the contact beam (24a, 24b) so that a point of restraint on the contact beam (24a, 24b) is selectively variable. The contact force between the contact beam (24a, 24b) and the male contact can thereby be varied on a selective basis.
