Abstract: A card edge connector with an improved manner of creating a preload force on conductive elements held by a housing. The housing may include a member and an opening at a mating end. Each conductive element may have a contact portion curving inwardly relative to the opening and a tip extending from the contact portion towards the mating end. Each contact portion may form an electrical connection with an edge pad of a card to be inserted into the opening. The conductive elements may be configured to have a rest state in order to create a proper force to be exerted on the edge pads. The member may preload the conductive elements by contacting the conductive elements from a location farther from the mating end than the contact portion, which may avoid damage upon insertion of a card into the connector without the need for long tips of the conductive elements. As a result, the connector may operate at high frequencies.

A second electrically conductive trace is providing on the substrate proximate the first electrically conductive trace. A solder mask is provided at the first and the second electrically conductive traces. A portion of the first electrically conductive trace is free of any portion of the solder mask covering thereon.

The switching regulator includes a peak detector configured to receive a clock signal and detect a peak voltage of the clock signal, a comparator configured to generate a soft start signal for controlling a soft start of the switching regulator based on a result of comparing a level of the peak voltage of the clock signal to a preset reference voltage level, a counter configured to switch a state of the soft start signal at a time point when a preset soft start time arrives, and a ramp voltage generation unit configured to generate a ramp voltage by adjusting a resistance of a variable resistor based on the soft start signal.

Abstract: A card edge connector with latching that enables a compact connector. The connector includes a latch, centrally located along the connector. The latch may be aligned with an alignment rib of the connector housing, reducing the space required for the latch. In some embodiments, portions of the latch may be bifurcated so that the latch may straddle the rib. In this way, space for a latch in a circuit assembly using the connector may be less than in conventional connector with latches on each end.

Abstract: An input/output connector system with a cable assembly that routes signals over a circuit board to which a receptacle connector is attached.

The cage has an opening in a top surface through which a plug may be inserted into the channel to mate with the receptacle. The cage may be formed with one or more keys that engage channels on the plug to constrain motion of a plug inserted through the top surface to a direction perpendicular with the circuit board until the plug is inserted sufficiently into the cage that it can slide towards the receptacle without damaging the plug or receptacle. The plug may have one or more latch components on the sides, which engage with corresponding latch components on the cage when the plug is slid into engagement with the receptacle connector.

The mounting ends of the signal contacts may be disposed in pockets in a surface of the connector housing. In some embodiments, solder balls may be fused to an edge of the signal contact, with the length of the edge extending beyond locations at which the solder ball is fused to. The edge may extend through a wall of the pocket, so as to set a desired impedance in the mounting region of the connector.
