Problems solved by technology

For example, the stake section can increase signal loss by acting as an antenna that discharges power from the connector
In addition, stake sections can negatively impact the impedance at the mating interface, which increases the resistance at the mating interface
Additionally, the stake section may provide a path for electrical resonance to reflect back and forth along the length of the contact, causing standing waves that degrade signal transmission performance

Embodiment Construction

[0013] figure 1 is a front perspective view of electrical connector system 100 showing components in an unmated state and ready for mating, according to an exemplary embodiment. The electrical connector system 100 includes a circuit board 102 and a receptacle connector 104 mounted to the circuit board 102 . The receptacle connector 104 is configured to be electrically connected to the header connector 105 to provide a conductive signal path between the circuit board 102 and the header connector 105 . Receptacle connector 104 may be a high speed connector that transmits data signals at speeds in excess of 10 gigabits per second (Gbps), such as in excess of 25 Gbps. The receptacle connector 104 may also be configured to transmit low speed data signals and / or power. The receptacle connector may alternatively be an input output (I / O) connector.

[0014] The receptacle connector 104 includes a housing 106 extending between a front end 108 and an opposite rear end 110 . As used ...

Abstract

A receptacle connector 104 includes a housing 106 and a plurality of contacts (116) held in the housing. The housing extends between a front end 108 and an opposite, rear end 110. The housing definesa card slot 112 that is open at the front end for receiving a mating plug connector 105 into the card slot through the front end. The contacts include deflectable spring beams 134 exposed in the cardslot and configured for electrical connection with the plug connector. Each of the spring beams extends continuously from an arm 170 to a distal tip 172. The spring beams include bends 174 between thearms and the distal tips. The bends are located at front ends 176 of the contacts such that the distal tips and the arms of the spring beams are disposed rearward of the bends.

Description

technical field [0001] The subject matter herein generally relates to a receptacle connector with stakeless contacts. Background technique [0002] High-speed electrical connectors typically transmit and receive data signals across a mating interface. For example, some known receptacle connectors are mounted to a circuit board and include a card slot that receives a card edge of the plug connector at a mating interface. The receptacle connector has contacts at the mating interface with deflectable spring beams that are spring loaded against the plug connector when the plug connector is loaded into the slot. [0003] However, known socket connectors are not without disadvantages. For example, the spring beam in some known receptacle connectors includes a lead-in portion extending from the contact location (which is the area of ​​the spring beam that engages the plug connector) to the distal tip or end of the spring beam. As the plug connector is loaded into the bay, the le...
