    Abstract: A plug-in circuit board assembly requires reduced insertion force during connection to a plurality of shorting contacts in a socket or receptacle. The connector portion of the circuit board assembly has a pair of end sections with beveled insertion edges that extend substantially perpendicular to the insertion direction of the circuit board. A shallow V-shaped cut-out with non-beveled insertion edges is located between the end sections. Electrically conductive fingers are carried by the connector portion of the circuit board assembly and extend toward the insertion edges of the end sections and V-shaped cut-out. The electrically conductive fingers adjoining the V-shaped cut-out are positioned to make contact with shorting contacts in the socket or receptacle, while the electrically conductive fingers of the beveled end sections are positioned to make contact with conventional (non-shorting) contacts in the socket or receptacle. The angled insertion edges of the V-shaped cut-out cause the electrically conductive fingers adjoining the cut-out to make contact with the shorting contacts in a sequential or progressive manner when the circuit board assembly is inserted into the socket or receptacle, thereby reducing the insertion force that would otherwise be encountered due to the absence of a bevel on the insertion edges of the cut-out

    Abstract: A circuit card capable of live insertion into an activated electronic system includes a terminal edge from which an edge connector extends a first length. An input decoupling capacitance resides across the edge connector. A backplane within the activated electronic system receives the circuit card, wherein the backplane includes at least one voltage plane, a backplane receptor, and card guide receptor means. The backplane receptor electrically couples the edge connector to the voltage plane when the edge connector engages the backplane receptor. Card guide means are provided for guiding and connecting the circuit card into the backplane, and include at least one conductive member for engaging the card guide receptor means. The conductive member extends a second length from the terminal edge, wherein the second length is greater than the first length. At least one conductive path electrically couples the conductive member across the input capacitance. A voltage supply applied to the card guide receptor means ensures that during insertion of the circuit card into the backplane, but prior to the backplane receptor engaging the edge connector, the input capacitance will pre-charge through the conductive member, thereby preventing arcing and voltage dropout.

    Abstract: An electrical connector includes a body and two or more electrical contacts. The body has a guide member that is elongated between a first end and a second end along a first axis and has a connector block at the first end. The connector has a very low profile (preferably, less than about 10 mm high), and the bottom of the body is surface-mountable on a circuit board. The height of the connector can be defined by a vertical axis perpendicular to the first axis. The connector block retains the contacts, which are spaced from one another in the direction of the first axis. The body also has a camming element that, in response to a force of a mating connector being moved along the first axis, brings the contacts of the connector and mating connector together in a generally vertical direction. The camming element may have two oppositely inclined ramp sections. When a mating connector having complementary contacts is, guided by the guide member, moved into engagement with the camming element, the first ramp lifts the mating connector, including its contacts, above the connector block, and the second ramp lowers the mating connector onto the connector block, with the contacts of the mating connector lowering onto and making contact with the contacts of the electrical connector. The camming motion minimizes wiping between the mating contacts and largely confines the relative motion of the contacts to a vertical direction. The contacts may be arrayed in two or more rows.

    Abstract: A circuit card is interfaced to a powered electrical bus by applying power to the circuit card before it interfaces to the electrical bus or by removing power from the circuit card after it has been removed from the bus. This is accomplished using a power cord that connects the equipment's power supply to a mating connector on the card to be inserted or removed. Attaching the power cord to the mating connector of the card disables the output drivers that provide output signals to the equipment's communication bus and places the card in a reset state. This prevents introducing error signals onto the communication bus. Additionally, the contacts on the edge connector are sequenced to prevent applying power to the circuit card before a ground is available. Additionally, the power cord and circuit card are keyed to prevent improper insertion and the power card includes an inductor to provide surge protection.

    Abstract: An insulation displacement contact comprises first and second contact portions each of which comprises a cantilevered split beam. The upper split beam, which receives insulated wires, comprises a pair of tynes which are folded about the axis of a slot separating the tynes such that the internal angle between the tynes is approximately 90.degree.. The width of the times is larger than that of prior art devices resulting in increased stiffness and the length of the tynes is sufficiently long to receive two wires therebetween.The contacts are mounted in a housing which includes a plurality of teeth provided with means for retaining lugs on the end of the tynes to ensure bowed opening of the tynes on insertion of a wire. The contacts are arranged along the central axis of the housing such that the folded tynes of alternate contacts extend on opposite sides of the central axis.

    Abstract: An electrical connector includes a spring contact member mounted in a housing which has an opening for receiving an edge of a printed circuit card. The spring contact member has a contact area urged into electrical connection with a contact pad on the printed circuit card as the edge of the board is inserted into the opening. The spring contact member has a dog-legged portion extending from the contact area in the direction of insertion of the printed circuit card to define a recessed area of the spring contact member facing the board in the opening. The recessed area of the spring contact member is aligned with the contact pad when the printed circuit card is fully inserted into the opening in the housing.
