摘要： An electrical connector is provided for insulation displacing termination of ribbon cable having insulated conductors in predetermined close centerline spacing. The connector includes a dielectric housing having a mating face, an opposed cable-receiving face and a plurality of terminal-receiving passages extending between the faces for receiving a plurality of terminals. Each terminal includes a mating portion toward the mating face and slotted U-shaped insulation displacement portion toward the cable-receiving face. The insulation displacement portions of the terminals are arranged staggered in at least two rows. A dielectric cover forces the conductors into the U-shaped insulation displacement portions and embraces the cable between the cover and the cable-receiving face of the housing. The cover includes a surface for engaging the cable and recesses in the surface for receiving the U-shaped insulation displacement portions of the terminals. The surface of the cover defines a plurality of parallel conductor support channels. Each channel defines upper and lower conductor support levels arranged such that a lower conductor support level of one channel is between two upper conductor support levels of adjacent channels. Projections are formed in each channel to hold a respective conductor therein. Therefore, the ribbon cable can be pressed into the conductor support channels of the cover and held on the cover for subsequent termination of the cable to the terminals on the connector housing.

摘要： An electrical connector assembly having a low insertion force, high normal force mating contact structure comprising a male terminal and a female terminal. The contact portions of the female terminal are adapted to electrically engage the lead-in portion of the male terminal as the male terminal is inserted into the mouth between the contact portion of the female terminal. The lead-in portion of the male terminal is split and defines a pair of diverging beams extending forwardly and angled outwardly from the final contact area. The beams have inwardly facing, laterally offset, opposing camming portions adapted to engage and increasingly deflect the contact portions of the spring arms of the female terminal as the male terminal is moved from an initial position to a final position wherein the female contact portions are in engagement with the final contact area of the male terminal. The normal forces between the contact portions of the spring arms and the corresponding camming portion gradually increase until the final mated position is achieved. The split male configuration allows for increased terminal mating length and adjustment of the wiping action of the contacts as desired.

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.
