摘要： A method and structure of an electrical connector is provided for tuning the impedance of the connector according to a given impedance of an electrical circuit in which the connector is interconnected. The connector includes a dielectric housing having a receptacle for receiving a complementary electrical component. A plurality of terminals are mounted on the housing. The terminals include body portions located in the housing and contact portions for engaging respective contacts on the electrical component. The body portions include mechanically nonfunctional sections of a given area which effect a given capacitance. The mechanically non-functional sections are selectively trimmable to selectively vary the area thereof and thereby vary the capacitance of the terminals and, therefore, the impedance of the connector to match the given impedance of the electrical circuit. The connector includes a plurality of signal terminals and a plurality of ground terminals. The ground terminals have at least two points of contact for engaging a common ground circuit on the printed circuit board for reducing the inductance between a particular ground terminal and its respective circuit trace.

摘要： A method is disclosed for terminating a coaxial connector to a coaxial cable. The coaxial connector has an elongated signal pin surrounded in part by an insulating jacket and an elongated shield member surrounding the insulating jacket while the coaxial cable has a signal wire surrounded by an inner insulating member, ground means surrounding the insulating jacket and an outer insulating sheath surrounding the ground means. The method includes providing an elongated conductive shield member having a front portion and a rear portion. The front portion of the shield member is secured onto the insulating jacket surrounding the signal pin whereby a portion of the signal pin is positioned within the rear portion. The ground means is electrically and mechanically bonded to the rear portion of the shield member. The signal wire is then electrically and mechanically bonded to an exposed portion of the signal pin within the rear portion of the shield member while the signal pin is held by the shield member. The rear portion of the shield member is then closed around the bonded portions of the signal wire and the ground means.

摘要： A female electrical contact is disclosed to include an elongate body having a terminal portion at one end and a receptacle portion at the other end for receiving a complementary male pin. A pair of cantilevered arms are provided of substantially equal length and in opposed relationship to each other with contact portions at their distal ends. The cantilevered arms are axially offset from each other in the longitudinal direction of insertion of the complementary male pin, whereby the male pin engages the contact portions sequentially. The cantilevered arms are bowed inwardly so that the contacted portion of one of the arms engages the other arm under a preload.

摘要： A card edge electrical connector is shown for providing electrical connections between a printed circuit card and a printed circuit board wherein the printed circuit card has either a 32 bit or a 16 bit capacity. The connector includes a housing having a retaining post that is inserted into an aperture of the printed circuit board to retain the connector to the printed circuit board. The retaining post is tubular having an axial slot extending through the sidewall thereof so as to be resilient and durable. Further, each of the contacts disposed within the connector housing includes a stabilizing arm that opposes the forces created by the insertion of the printed circuit card into the connector housing so as to distribute the opposing forces between the stabilizing arm and the base of the contact. Contacts of alternating sizes and having beams of different angles with the base are employed in the connector. However the contacts have equal path lengths between the printed circuit board and the top of the connector housing through the respective contacts.
